Good Practice Guidelines from the Okavango
Delta Case Study on the Integration of Freshwater
Biodiversity Information into Development Planning
Jessica Jones, William Darwall, Cornelis van der Post, Susan Ringrose
Wetlands provide many important goods and services ranging from food and building materials, to water
filtration, flood and erosion control, and are a critical resource for the livelihoods of many of the world’s
poorest communities (Millennium Ecosystem Assessment 2005). While freshwater systems make a big
impact in terms of global biodiversity, they are under growing pressure worldwide as flow patterns are
disrupted and the load of waste substances increases. Runoff from agricultural and urban areas, the
invasion of exotic species, and the creation of dams and water diversion are key threats.
Overexploitation, flow modification including water abstraction, destruction or degradation of habitat, and
invasion by alien species and pollution also threaten freshwater species. Predicted global climate change
will compound these threats (Dudgeon et al. 2006; Millennium Ecosystem Assessment 2005). In fact
climate change is a much worse treat if the current global climate models are to be believed (Wolski et al
2002). Botswana’s Okavango Delta illustrates the kinds of threats typically faced by wetlands in Africa.
A case study was carried out in Botswana’s Okavango Delta in 2007-2008 aiming to get information
about freshwater biodiversity utilised practically within the development planning process. This project
was one of four IUCN-supported pilot efforts across Africa with the same aim, but piloting different
mechanisms and with different circumstances. The Okavango Delta case used the mechanisms of a long-
term water quality monitoring programme and an outreach book for stakeholders and decision-makers. A
freshwater biodiversity baseline was applied through wetland health monitoring tool (index of biological
integrity) that is being piloted and will yield management-oriented information for years to come. The
visually appealing book highlighting freshwater species and issues will reach decision-makers rapidly and
serve to pilot a reporting tool for communication about the status of freshwater biodiversity and wetland
health. The Okavango case was unique in being preventative – addressing largely perceived rather than
actual threats to the Delta.
Numerous lessons were learned from the process of trying to get decision-makers to use freshwater
biodiversity in a strategic and efficient manner within the day-to-day reality of decision-making processes.
Recommendations arising from this experience are applicable to other similar efforts within similar
circumstances.

Introduction
The Okavango Delta case study was one of four pilot efforts across Africa trying to integrate information
about freshwater biodiversity into the development planning process. The Okavango Delta case used the
mechanism of a long-term water quality monitoring programme and later, an outreach book. The available
freshwater biodiversity information was integrated into a wetland health monitoring tool (index of
biological integrity) that is under development for long-term use, and the Delta book will reach decision-
makers more immediately and pilot a reporting tool for communicating about freshwater issues. Varying
degrees of success were achieved trying to get decision-makers to use freshwater biodiversity datasets in
planning and numerous lessons were learned from the process of trying. Recommendations arising from
this experience applicable to other similar efforts are offered in this report.
The global importance of freshwater biodiversity
Water is the basis of life, and fresh water systems are among the most productive life-support systems in
the world. Wetlands in particular provide many important goods and services ranging from food and
building materials, to water filtration, flood and erosion control, and are a critical resource for the
livelihoods of many of the world’s poorest communities (Millennium Ecosystem Assessment 2005). While
having a relatively small coverage, freshwater systems make a big impact in terms of global biodiversity.
Freshwater biodiversity refers to the natural variety, abundance, and distribution of species found in these
freshwater ecosystems. The diversity of species in freshwater habitats is disproportionately high as
compared to other ecosystems. Freshwater habitats cover less than a percent of the world’s surface, yet
they provide a home for over 25% of all described vertebrates, more than 126,000 known animal species,
and approximately 2,600 macrophyte plants (Darwall et al 2008). An estimated 12,500 fish, 5,700
amphibian and 4,000-5,000 mollusc species depend on freshwater habitats (IUCN 2009). Other major
groups dependent upon freshwater habitats include reptiles, insects, plants, and mammals. In total, there
could be up to a million species included in the definition of freshwater biodiversity.
There are three major categories of ecosystem services provided by freshwater biodiversity: provisioning,
supporting, and cultural (Millennium Ecosystem Assessment 2005). Provisioning services include: the
delivery of clean water, providing food (e.g., rice, fish, crayfish) or goods used by humans (e.g., reeds as
building material), and resilience to anthropogenic impacts (e.g., pollution, excessive nutrients release).
Supporting include: suppression (a service) or enhancement (a disservice) of water-borne diseases, flood
attenuation in flood prone areas, delivery of sediments to coastal areas (e.g., beach and dune formation).
Cultural services include: recreation, tourism value, inspiration, and religious applications. These goods
and services are valued comparably to the GDP of some countries in the top third of the world’s
economies (Darwall et al 2008).
The overriding value of freshwater biodiversity is scale dependent. At the global level, freshwater
biodiversity is primarily seen in terms of its great role in maintaining our biosphere. Though freshwater
covers only 0.8% of the world’s surface, it contains 12% of all described species and supports the
maintenance of most others forms of biodiversity. Freshwater ecosystems in continuous flux can make a
range of habitats available at different times of the year to terrestrial and arboreal animals, supported by
freshwater species, which are thus critical for the maintenance of global biodiversity (McAllister et al 1997;
Abramovitz 1996). Nationally, the value of freshwater biodiversity can be measured in terms of
contribution to Gross National Product through national accounts and satellite natural resource accounts.
The most prominent examples of freshwater connected economic value are related to fisheries and
6
tourism. Locally, freshwater biodiversity directly and indirectly
supports livelihoods. Many people, but most acutely the
world’s poor, depend on the services provided by freshwater
biodiversity for their livelihoods. It supplies food, water
purification, flood regulation, and protection. Most fish caught
in freshwater is done so using the least sophisticated methods
and eaten very close to source, demonstrating that freshwater
fish species supports the nutrition of the poor. Additionally,
many serious human diseases are water-borne or spread
through aquatic vectors (e.g. malaria, schistosomiasis,
onchocerciasis, cholera, dysentery) so the maintenance of
freshwater biodiversity is a key link in preventative health
strategies.
Freshwater biodiversity has already begun to decline, and it
has declined faster compared to terrestrial or marine species
over the past 30 years (Xenopoulis 2005). Rapidly growing
global human populations demand increasing volumes of
water. Freshwater systems are under growing pressure, as
flow patterns are disrupted and the load of waste substances
increases. Runoff from agricultural and urban areas, the
invasion of exotic species, and the creation of dams and water
diversion are key threats. Overexploitation, flow modification
including water abstraction, destruction or degradation of
habitat, and invasion by alien species and pollution also
threaten freshwater species (Dudgeon et al. 2006; Millennium
Ecosystem Assessment 2005). Predicted global climate
change will compound these threats. Temperature changes
and shifts in precipitation and runoff patterns will have knock-
on effects to freshwater biodiversity (Dudgeon et al. 2006).
Another major issue is acidification which along with warming
threatens a number of species. Ones with calcareous shells
such as Crustaceans are highly vulnerable. Water monitoring
exercises at HOORC are currently assessing pH changes.
In order to help mitigate the threats and better inform the
development and conservation planning process, we need to
know where freshwater species occur, how important they are
for human livelihoods and ecosystem functioning, and how
threatened they are and by what. To achieve this, information
on species distributions, population status and trends, habitats
and ecology, threats and utilisation are collated and used to
conduct assessments of extinction risk. The information is all
made available on the IUCN Red List of Threatened
Species™ (IUCN 2008).
Box 1: The Ramsar Convention
The Convention on Wetlands, signed in Ramsar, Iran, in 1971, is an intergovernmental treaty which provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources. There are presently 158 Contracting Parties to the Convention, with 1822 wetland sites, totaling 168 million hectares, designated for inclusion in the Ramsar List of Wetlands of International Importance.
The Convention’s mission is the “conservation and wise use of all wetlands through local, regional and national actions and international cooperation, as a contribution towards achieving sustainable development throughout the world.” Its three pillars of implementation are: (1) the wise use of all wetlands; (2) special attention to internationally important wetlands; and (3) international cooperation.
The Convention has recognized the interdependence of people and their environment, and is the only global convention addressing interactions between water and ecosystems.

The Okavango Delta Site
The demonstration site of the case study is the Okavango Delta (see Figure 1: Map of the Okavango ),
Botswana, forming one of the world’s largest area Wetland of International Importance. The Okavango
Delta is protected through the Ramsar Convention on Wetlands (see Box 1 at right).
As a site of global importance for biological conservation and diversity, the Delta is a significant habitat for
terrestrial and water bird species with 444 bird species confirmed. Thirteen resident bird species,
including the Wattled Crane (Burgeranus carunculatus) and the Slaty Egret (Egretta vinaceiqula), are
globally threatened and many data deficient species may also be classified as such. The Delta contains
high densities of large mammal species particularly elephant (Loxodonta Africana). It is also the habitat of
one of the largest remaining populations of the African wild dog (Lycaon pictus) and is a stronghold for
the Sitatunga antelope (Tragelaphus spekii), the Nile crocodile (Crocodilus niloticus), and leopard
(Pathera pardus). There is ahigh floral diversity with 208 aquatic and semi-aquatic species, 675 herbs
and grasses and 195 woody species. One endemic has been identified, the ground orchid (Habenaria
pasmithii). A number of other plant species found in the Delta have been identified as rare or endangered
(Ramberg et al 2006).
At a national scale, the Delta contributes 2.1% of Botswana’s Gross National Product (Turpie 2006)
primarily through tourism but also through limited fisheries and other subsistence resource uses. The
measurable economic value of the Delta is overwhelmingly dominated by non-consumptive uses of the
resource through ecotourism. Tourism provides around 50% of formal employment in northern Botswana,
and 9.2% of total employment in Botswana -- or 1 in every 10.8 waged jobs (Arntzen 2005; WTTC 2007).
Tourism is the second-highest earner of foreign currency for Botswana after diamonds (WTTC 2007).
Households in and around the Delta earn an estimated total of $31USD million per year from natural
resource use, sales, salaries and wages in the tourism industry, and rents and royalties in community-
based natural resource management (locally known as Community Trust) arrangements (Turpie 2006).
Many are directly dependent on the Delta for subsistence, and consequently, the population is clustered
in a band of settlements around the Delta. Options for subsistence outside the Delta are limited as the
natural resource base of northern Botswana is marginally productive. Soils are generally poor, rainfall is
low and unreliable and although significant mineral deposits have recently been discovered, mines have
not yet been developed (Turpie 2006). The Delta’s wetland resources are a lifeline for thousands of
Botswana’s poor.

The Okavango Delta is under threat. Global climate change will lead to higher ambient and water
temperatures and faster evaporation, resulting in faster drying up of seasonal swamps. The increase in
CO2 concentrations may alter the composition of the vegetation, and increase the woody biomass.
Changes in rainfall levels in Angola and rainfall variability will have an impact on the inflow, but the nature
of the impact is not known at the moment (Wolski and Murray-Hudson 2008).
The Delta depends on the water inflow from Namibia and Angola. Increased upstream water abstraction
and pollution form the major threats from these countries. Local uses (agriculture, fishing, resource
collection and use) could alter the resource base and biodiversity due to growing commercial and
subsistence use of the Delta and its resources. The Government of Botswana, through the Department of
Environmental Affairs, has expressed concern about the depletion of some veld products, overgrazing
and land degradation and the environmental impacts of the growing number of tourists.
If these threats are not addressed, they will have a profound impact on the freshwater biodiversity.
Commercial and artisinal fish species, threats to aquatic and terrestrial plant life, and animals such as the
Sitatunga are significant and also the wider structure and functioning of the Delta is at risk. Specific
changes are likely to directly affect local communities that are heavily dependent on the Delta for their
livelihoods, including consumptive and non-consumptive tourism
The available evidence suggests that, without appropriate intervention, the Okavango Delta of the future
will be potentially very different from what exists today.

The African Freshwater Biodiversity Project
The African Freshwater Biodiversity Project, “Integration of
freshwater biodiversity in the development process throughout
Africa: mobilising information and site demonstrations” is
implemented through the IUCN Species Programme
Freshwater Biodiversity Unit (see box at right). It has been
funded by the European Commission Program on
Environment in Developing Countries (Program on Tropical
Forests and other Forests in Developing Countries).
In the first phase of the project, regional Biodiversity
Assessments collated all existing information on African
freshwater biodiversity (fish, molluscs, odonates, crabs,
aquatic plants) (see figure 2 below). IUCN has completed
comprehensive assessments for eastern Africa and southern
Africa and ongoing assessments for the rest of Africa are to be
completed in 2009. These regional assessments provide a
comprehensive picture of the status of freshwater biodiversity.
They also allow for the basins that contain high numbers of
species or threatened species to be identified. The
conservation status of freshwater species was assessed,
species ranges were mapped, and findings were presented in
a suitable format (regional reports). This effort represents the
most comprehensive dataset ever compiled on Africa’s
freshwater biodiversity.
Box 2: IUCN Freshwater
Biodiversity Unit
The IUCN Freshwater Biodiversity Unit (FBU) aims to put in place a factual basis for efforts to conserve and manage freshwater biodiversity globally.
The FBU works in conjunction with the IUCN Species Survival Commission’s Specialist Groups (including the Freshwater Fish, the Dragonfly, and the Mollusc Specialist Groups), regional scientists, experts in freshwater biodiversity, and policy makers. The FBU has a key partnership with Conservation International's Center for Applied Biodiversity Science, working to undertake regional and global freshwater biodiversity assessments.

In this second phase, four Demonstration Sites in major regions of Africa are used to demonstrate (all are
still ongoing into 2009) how to integrate biodiversity information within the development planning process
of their respective countries. Each site faces different conditions and approaches the task through
different means:
Southern Africa: The Okavango Delta is unique in largely facing both potential and
than actual threats, and thus has the opportunity to establish information gathering
from a baseline state. This site demonstrated a process for the integration of
biodiversity information in the development and implementation of the Okavango Delta
Management Plan (ODMP), a comprehensive and integrated management plan
developed to meet Ramsar Convention requirements. This Delta faces threats from
the developments of its upstream neighbours, Angola and Namibia in addition to
inceasing tourism pressures thus lessons derived from this demonstration can also be
useful when considering a basin-wide context. Locally, lessons can be learned from
the ongoing process of implementation of the ODMP, including its challenges.
Eastern Africa: In Burundi, the Rusizi
case study demonstrates the process
for applying biodiversity information for
the development of a transboundary
environmental management plan in an
inland Delta and river system subject to
the impacts of heavy agricultural use
and shared by three neighbouring
countries: Burundi, Democratic Republic
of Congo and Rwanda. This project
focuses on the collection, analysis and
dissemination of biodiversity information
for integration within management
processes within its lower Delta. It is
also an area which has experienced
conflict and has current security
concerns, which presents a significant
dimension for analysis.
Northern Africa: Morocco’s Moulouya
River case study will demonstrate a
process for integrating biodiversity
information for determining
environmental flows in a river basin
subject to high demands on water
resources for agriculture and potable water and
for flood control measures. The project assist to
define the downstream flow needs from river
regulation infrastructure (hydropower and
irrigation dams) that would be required to
maintain downstream biodiversity values and
ecosystem functions.

Western Africa: The Gambia River Basin demonstration site will track the impacts of
a hydro-electric dam on the Gambia River. The aim is to develop a system for
continuous monitoring of biodiversity by local stakeholders as well as national
environmental agencies which will be integrated into a formal structure. The creation
of an observatory is one of the priorities. This project is in direct response to an acute
threat to the river.
Together the four demonstration sites will, having collated the most comprehensive set of data on African
freshwater biodiversity, offer insight on how to take the next crucial step of integrating this available data
into development and environment decision-making and planning processes. It is at the demonstration
site stage that this project really stands out from other biodiversity assessments. Many assessments have
gone so far as producing data and reports aimed at decision-makers, without going the extra step to help
ensure that these are utilised effectively by their target audiences. In practice, many conservation
assessments have failed to ensure that their outputs are useful to local planners and do not sufficiently
address the local applications in which such data could be utilised. The pan-African IUCN project has
aimed to excel in that respect. Significantly, each of the four demonstration sites has had a local
coordinator specifically tasked with ensuring the information produced is used by decision-makers
through the available local mechanisms. These are all pilot efforts; lessons from and consideration of this
process form the heart of these site-level Good Practice Guidelines to inform similar future efforts. By
synthesising these four sets of lessons, taking their different contexts into consideration, the overall IUCN
project will then (in 2009-2010) be able to make recommendations of actions suitable for Africa-wide
application.
Overview of the Good Practice Guidelines
These Good Practice Guidelines are targeted to others planning and carrying out similar conservation
initiatives, specifically the application of biodiversity datasets in development and conservation planning
as a project or programme (sustained long-term strategic effort). The Okavango case study is an example
where this was envisaged primarily through integration with a programme of water quality and wetland
health monitoring. Another key vehicle for biodiversity information was a book aimed at decision-makers
and stakeholders to raise awareness of the importance of freshwater biodiversity, and build anticipation
for the results of the monitoring programme. The Guidelines reflect on how the IUCN Okavango Delta
Case Study was carried out. At the site level and from the perspective of the local coordinator, these
Guidelines offer guidance on how the objectives could be reached. The Guidelines could be applied
either in the context of a similar project or for sustained work at the same location.
The report is laid out in four parts:
Part 1: Aims of the IUCN Okavango case study. Reviews the objectives of the Okavango Delta
demonstration site and how it is useful as a case study.
Part 2: General recommendations emerging from the case study. Provides recommendations
which might be applied to similar projects or long-term efforts, substantiated through the
experience of the Okavango case study.
12
Part 3: Case-specific experience and lessons learned. Gives an overview of the progress
made through the Okavango demonstration site in its specific context. Lessons learned which
form the basis of the recommendations in Part 2 are explained in more detail.
Part 4: Guidance for successful interventions in the Okavango Delta. This section is
specifically targeted to future conservation projects, programmes or interventions formulated for
the Okavango Delta. It aims to enhance the “tacit” knowledge of individuals and institutions
undertaking similar conservation efforts in the Okavango Delta.
Part 1: Aims of the IUCN Okavango case study
The objective at the Okavango Delta demonstration site was to successfully apply the southern Africa
freshwater data set in the development of a long-term biological monitoring programme within the
Okavango Delta Management Plan (ODMP) secretariat. The monitoring programme is meant to provide a
scientific basis to inform adaptive management efforts under the ODMP and according to Ramsar
Convention guidance. The Secretariat of ODMP, hosted in the Department of Environmental Affairs
(DEA) in north-west Botswana, would then ensure that freshwater biodiversity data will be used to plan
future development projects in the Delta and to assess those proposed by Botswana’s upstream
neighbours, Angola and Namibia. Another mechanism of the case study was to reach decision-makers’
desks more immediately through a book which both raises awareness of the Delta’ freshwater biodiversity
and generate excitement for the monitoring programme’s results. A significant output of this pilot
demonstration process is the recording of how it occurred, what worked or did not work, in order to
provide guidance for other similar efforts. These three key outputs are reviewed briefly here, and then in
more detail in Part 3 of these Good Practice Guidelines.
1. Long-term monitoring programme
The ODMP was developed as a requirement of the Delta’s declaration as a Ramsar site and in response
to potential and actual (realised) threats to the current existence and functioning of the Delta. These
threats include the proposed and actual large scale water abstractions, construction of hydroelectric
dams upstream, potential and actual impact of increased population in the catchment (after cessation of
the Angolan civil war), increases in large-scale irrigated and commercial faming, and the environmental
impacts of tourism and other local activities.
The Department of Environmental Affairs (DEA) has overall responsibility for the implementation of
ODMP while sector specific implementation is distributed among a dozen government departments and
agencies. Data and information needs are to be met by the University of Botswana’s Harry Oppenheimer
Okavango Research Centre (HOORC). A database, the Okavango Delta Information System (ODIS) is
meant to cover all aspects of the Delta and its surrounding area and act as a repository for any and all
information that is already thought to be, or might be in the future, relevant to current or future
development plans, and monitoring of global climate change effects. One of the Department of Water
Affairs’ (DWA) roles is to develop a water quality (chemistry) monitoring programme, a task which has
since been taken up by HOORC.
13
The IUCN case study has sought to develop a “freshwater biodiversity monitoring system” that can be
used in conjunction with, or instead of, the chemical monitoring or biological monitoring of specific
indicators such as macro-invertebrates. It was envisaged that DWA could collect and collate this
information on a regular basis and use it to conduct such a freshwater biodiversity monitoring programme.
Capacity restrictions have since spread responsibility for implementation of this programme to HOORC
(lab support), tourism operators (sampling and logistics), and the Biokavango project (funding, equipment,
training, staff support).
The value-added of the IUCN demonstration site to the development of a freshwater monitoring
programme lies primarily in the development of species-based indicators for water quality and wetland
health and provision of a baseline condition against which to monitor for change. While chemical and
physical analyses are reliable (accurate, repeatable) and provide ‘instant’ snapshots’, they are: limited to
the period of sample collection, limited to the constituents measured, expensive (if comprehensively
done), and limited by sensitivity of the methods used (for example low concentrations cannot be
detected). Species of living freshwater organisms, however, provide for a longer-term reflection of
environmental conditions view and are continuous monitors: they integrate effects of time and multiple
pollutants. Freshwater species can be cheap and easy to assess, can be used for different purposes, and
can account for synergistic (magnifying) and antagonistic (reducing) effects (e.g. pH).
Combined with or instead of chemical monitoring, biological indicators can constitute a powerful wetland
health monitoring tool. In a biological assessment, investigators evaluate the condition of one or more
biological "assemblages"; examples of assemblages are macroinvertebrates, plants, or fish. For example,
diatoms are good indicators/pointers/markers for understanding aspects of water chemistry, macrophytes
can measure are indicators of hydroperiod / water level, fishes are sensitive to forms of pollution that
chemical tests may miss, and benthic macro-invertebrates can indicate generalised impairment of water
quality. Macro-invertebrates are particularly advantageous indicators. They represent important links in
the food chain as recyclers of nutrients and food for fish, and as relatively sedentary residents of the
stream bottom, benthic macro-invertebrates often become a pollutant's captive audience. While fish can
swim away from some pollution problems and even regular chemical tests of the water column may fail to
detect transitory or short-lived events, macro-invertebrates cannot swim away from pollution. Therefore,
they can be affected by even subtle levels of degradation within the substrate, even though the chemical
make-up of the water itself may be clean. Some are intolerant of pollution. Their presence in the stream
suggests healthy conditions. However, others are quite tolerant of pollution. Taken together, the presence
or absence of tolerant and intolerant types can indicate the overall health of the stream. Many macro-
invertebrates tend to have short life cycles, usually one season or less. Macro-invertebrates are easy to
collect and the equipment used is fairly simple and inexpensive. They are also fairly easy to identify at
family level and lend themselves well to situations with limited capacity.
Numerous bioassessment techniques have been developed over the last three decades, varying in the
level of complexity and region of implementation. Within Africa, South Africa has an exemplary history in
this field, culminating in the refinement of invertebrate and other techniques and their application in a
National River Health Programme. The highly successful SASS (South African Scoring System) method
(Chutter 1994) forms the backbone of this programme. SASS is now in its fifth iteration (SASS5), and has
been tested and is being refined locally as the Okavango Scoring System (OKAS).
14
Through a meeting of experts on the Okavango’s freshwater biodiversity and one-on-one meetings with
the OKAS developer, available information on the Delta’s freshwater biodiversity is known and available
to the individual developing and testing the OKAS. By setting up communication channels between
information providers and the consultant hired by the Biokavango project to test and refine the method, it
can be assured that all available information on freshwater species will be incorporated into the OKAS.
Thus, the information collated by IUCN on freshwater biodiversity will directly improve development
planning in the basin over the long-term through this tool, forming a major part of a long-term water
quality and wetland health monitoring programme.
2. Freshwater biodiversity profile
As many aspects of the long-term monitoring programme are slower to be realised than was anticipated
during the planning stage, development of a more immediate tool to get biodiversity information to
decision-makers was undertaken. The freshwater biodiversity profile of the Okavango Delta is a
collaborative book which will serve to:
- Bring biodiversity data to decision-makers;
- Pilot a communication tool for the results of the biological monitoring programme (derived through
indices of biological integrity);
- Raise awareness among stakeholders and particularly decision-makers about the importance of
freshwater biodiversity;
- Contribute to understanding about the usefulness of FWBD as an ecosystem health indicator at
the local scale and its global/regional biodiversity importance particularly as human
encroachment and climate change impact other African wetlands; and
- Describe the potential threats to the Okavango Delta and methods to reduce these, e.g.,
incorporating FWBD information into monitoring, Environmental Impact Assessment (EIA) and
awareness at the political level, e.g., through OKACOM.

15
The point of the book is to make this information attractive and digestible for its target audiences: policy-
makers, decision-makers, politicians (including Ministers and Parliamentarians), OKACOM (the
permanent Okavango River basin commission) members, upriver environmental agencies/groups, donor
agencies, local project administrators, private sector (especially tourism operators), researchers and
students, the media, interested residents, tourists to the Delta, and others. These partners can then play
an advocacy role to ensure that the FWBD is considered in the development planning process.
This tool was central to the impact of the Okavango demonstration site and met the objectives in a
complementary manner to the monitoring mechanism. By providing a tool for advocacy by stakeholders
the Okavango site added another mechanism through which IUCN can ensure its datasets are used to
improve development planning in the Delta.
3. Good Practice Guidelines
Although a difficult area of application for the IUCN dataset, it is critically important to understand how to
get decision-makers to use the available information on biodiversity for development planning. A major
component of the demonstration site was thus to document the process of how this could be achieved
and to share lessons learned in various efforts through this Good Practices Guide. This report aims to
provide guidance on taking that next crucial step – from the availability of biodiversity information to better
decision-making – based on the Okavango Delta case study.

Part 2: General recommendations from the case study
Documenting and reviewing the experience of the Okavango Delta case study has produced a range of
lessons learned which can provide guidance on what is likely to work in such a situation. Naturally, these
recommendations vary from tightly project-specific, to those which are more general, and are therefore
more widely relevant and replicable. This section reviews the general recommendations from this case
study, focusing on those which have broader relevance, and forming recommended approaches and
courses for other similar projects.
The recommendations are organised into these three overriding themes: strategies for designing
interventions; tools and methods for getting biodiversity information utilised; and adaptive management of
the implementation process. The specific recommendations under each theme are listed below and,
following that, described in more detail.
Recommendations for design strategy
1. Be demand-driven and value-added.
2. Conduct projects as part of a long-term and sustained engagement and partnership.
3. Stimulate local leadership for long-term monitoring through institutions, rather than
projects.
4. Provide “training, training, training” and tools to maintain capacity.
Tools and methods
5. Identify and work with critical local stakeholders who can carry out advocacy.
6. Build trust and identify incentives for information collation and exchange.
7. Understand incentives for academic participation in development work.
8. Be creative in the design of communication tools.
Adaptive implementation
9. Be realistic about the capacity and motivations for each stakeholder group to
contribute to monitoring.
10. Recognise where need exists for external support.
11. Be willing to adapt to changing circumstances in order to reach project objectives.
The expected benefits of sharing these recommendations are better, more focused and effective
strategies, tools and management approaches for integrating freshwater biodiversity datasets into
development planning at the site level.

Recommendations for design strategy
1. Be demand-driven and value-added.
There needs to be a strong ‘host’ with vision and power/capacity in order to successfully direct different
projects towards a common vision. In the Okavango case, there was an evident demand for the
freshwater biodiversity tool, but complicated arrangements without anyone with both the mandate and in-
house capacity to lead made it difficult to contribute effectively to its development. It would be difficult for
a project without a large budget and long-term engagement to lead such efforts. A similar project would
also need to find specific gaps in which they can contribute based on their relative strengths.
The IUCN project had four key points of value to add to ongoing work - IUCN’s freshwater species expert
networks, its own species dataset, research leading to an overall picture of the different/overlapping
initiatives occurring in the Delta, and momentum behind the development of the freshwater profile book.
The IUCN Okavango project was able to find a niche through which the project could make a tangible and
immediate contribution. Having a clear niche which addressed a widely-acknowledged gap made bringing
key stakeholders on board and working with partners much easier.
2. Conduct projects as part of a long-term and sustained engagement and partnership.
Much has been written about the utility of projects as a modality for conservation initiatives (for example,
McShane and Wells 2004; Jenkins and Williamson 2002; Honadle and Rosengard 1983). In an ideal
world funds would be available for long-term, sustained conservation efforts because, as with medical
care, conservation is better served by preventative measures rather than reactive measures or crisis
management. However, long-term programmatic funds are not the predominant modality of the donor
community, given their host of different pressures involved in accessing and distributing funds.
The benefits of sustained engagement for conservation work at the site level are highly valuable,
however. A long-term affiliation with an ecosystem and the players within can address many critical
bottlenecks to successful conservation efforts such as trust, limited background knowledge, and lack of
relationships or history. Because of the complexity of the operational environment in
conservation/development projects, particularly when local individuals view with suspicion the
involvement of short-term, external staff, organisational challenges are inevitable. Winning "hearts and
minds" is necessary for most conservation initiatives to succeed, but it can take a very long time.
Where IUCN is not or cannot be engaged locally through a country office, it should work to actively
develop partnerships in anticipation of the development of more projects. Ongoing engagement at both
the technical and political levels can be maintained with deliberate forward planning by funded projects.
Where a local office cannot be sustained, it may be worthwhile hiring a Liaison Officer for at least a few
hours a month to attend meetings, give presentations about the organisation, and otherwise remind
stakeholders of its presence and interests in sustaining conservation efforts. Tangible products such as
videos, books, websites/webgroups, user-driven email discussion lists and brochures also outlive project
life-spans and can maintain an important virtual presence.
3. Stimulate local leadership for monitoring through institutions, rather than projects.
18
As monitoring is by its nature a long-term endeavour, it should be led from within a permanent institution
to see it through. The Okavango Delta’s long-term monitoring programme has not yet been led from an
institution but has been input to by a patchwork of projects without a strong overall vision. Major funding
has come from a UNDP-GEF biodiversity project, but initiatives as of yet have not been driven from a
permanent, local institution. Ideally, a champion could be identified from government or the University
who could lead and organise efforts into a coherent and demand-driven programme. Encouraging such a
champion could be done through funding incentives, creation of a dedicated position, and awards. The
kinds of communication tools, management reactions possible, and ways to sustain capacity after current
training funding has ended also need forward-thought from the outset. However, recently the DEA has
been promised funding from central government under Botswana’s 10th National Development Plan
(NDP10) for monitoring work to be carried out in partnership with HOORC
Dr Jenny Day’s presentation to the Okavango Freshwater Biodiversity Experts meeting (Day 2007)
emphasised that monitoring for the sake of monitoring just does not yield valuable results. There must be
a vision for what kinds of information is sought, how this information can be collected efficiency (given the
great expense of regular field sampling), whom can be relied on to maintain oversight and quality, and
how results will then be utilised to influence
decision-making. Projects are by definition
time-limited whereas the demand for
monitoring is necessarily long-term. A
permanent institution needs to lead this
process.
4. Provide “training, training, training”
and tools to maintain capacity.
The importance of training and capacity
building efforts for the sustainability of a long-
term biological monitoring programme cannot
be overstated. To maintain quality and
ensure reliable results, appropriate
individuals need to be well-trained and
capable of carrying out the critical tasks at
each stage of the monitoring process. The
process of conducting a long-term monitoring
programme is only worthwhile if the
results/output are of a high quality; low
quality results/outputs will seriously
undermine the viability of the programme.
While a period of piloting through trial-and-
error is required, human capacity will be the
make-or-break factor in the success of a
monitoring programme.
In the case of the Okavango Delta, the
potential candidates for training in monitoring

techniques are highly transient; this poses a major risk to the success of
the programme.1 Government officials are rotated frequently from the
remote Delta posting, there is high turnover in lab staff at the University
research centre, and tourism operator staff are quickly moved around
camps to meet the demands of their core business. Additionally, HIV/AIDS
has taken an immense toll on the availability of individual capacity.
Individuals are often absent for medical appointments, funerals, are ill and
unable to work, or tending to family concerns in this region with 20-39%
HIV prevalence (GoB 2006). Given the expense of one-on-one training
and the degree to which such investment is quickly eroded, creative
strategies to sustain capacity are needed.
The Okavango demonstration site found that the production of durable
training materials such as video courses can be a more sustainable
method to maintain capacity than expensive one-on-one training. “User
friendly” training manuals should be available to act as a refresher for
those who have already been trained and assist in the familiarisation of
others in the monitoring techniques. IIED (Thompson 2002) has devised
guidelines for trainers in participatory learning and action methodologies.
These can provide some inspirational ideas for future monitoring training
methods.
One benefit of reliance on macro-invertebrate monitoring is that the level
of academic capacity required is much less than for chemical monitoring.
Trained volunteers have assisted biomonitoring using macro-invertebrates
since the Save Our Streams (SOS) programme was founded in 1969 in
the United States (Firehock and West 1995). The South African River
Health Programme (see Box 3, at right) successfully relies on volunteers
(amongst others, DWAF Regional Offices, provincial departments of the
environment, conservation agencies, universities and municipalities) to
generate information for improved management of its rivers. Skills
certification through an accreditation programme has been used in the
South African model to ensure that volunteers are adequately trained.
Qualifications for the South African Scoring System method expire and
must be renewed – a recommended method to maintain consistently high
standards of monitoring.
Tools and methods
5. Identify and work with critical local stakeholders who can carry out
advocacy.
1 This risk has been recognized since the initial project document for the pan-African project.
Box 3: South Africa’s River Health
Programme
South Africa’s River Health Programme (RHP) serves as a source of information regarding the overall ecological status of river ecosystems in South Africa. The RHP primarily makes use of in-stream and riparian biological communities (e.g. fish, invertebrates, vegetation) to characterise the response of the aquatic environment to multiple disturbances. The rationale is that the integrity or health of the biota inhabiting the river ecosystems provides a direct and integrated measure of the health of the river as a whole. The objectives of the RHP are to: 1. Measure, assess and report
on the ecological state of aquatic ecosystems;
2. Detect and report on spatial and temporal trends in the ecological state of aquatic ecosystems;
3. Identify and report on emerging problems regarding aquatic ecosystems;
4. Ensure that all reports provide scientifically and managerially relevant information for national aquatic ecosystem management.
The Department of Water Affairs and Forestry is the custodian of the programme and intends to institute legislation formalizing the RHP through the South African National Water Act (1998). The programme is supported by an accreditation programme in order to guarantee a high level of quality across all of South Africa’s provinces. More information on this programme can be obtained from www.csir.co.za/rhp/index.html.

The working environment of politicians and other decision-makers is a complex mixture of personal
feelings, technical inputs, social pressures, political considerations, and economic realities. Their jobs are
difficult, and involve difficult decisions. They are unlikely to be immediately influenced by detailed
technical reports alone. In reality, detailed technical reports are often not read by the people they are
targeted at. Time and competing priorities are the main culprits for this, rather than lack of interest or
capacity, but it is important to note that the latter do play their part.
Politicians and decision-makers do however respond more directly to pressure from within the
constituencies that they represent. It is thus critical to work with the local stakeholders groups who can
influence the political agenda. Community groups, local non-governmental organisations, industry
associations, traditional leadership structures and other bodies can campaign and raise public awareness
– and then decision makers may then take note of an issue. The role of IUCN or another scientific
organisation not involved in advocacy work is thus to provide appropriate information to support these
groups’ lobbying efforts. The Okavango freshwater profile produced by the IUCN case study is one such
example.
6. Build trust and identify incentives for information collation and exchange.
Open access to conservation information is essential to enable effective decision-making and to empower
those concerned with the management and conservation of biodiversity. Ideally all organisations and
individuals in this field would follow the principles of the Conservation Commons (see Box 4), which
promotes open access to sharing and use of conservation data, information, and knowledge resources by
all sectors of society.
21
Box 4: Principles of the Conservation Commons
Principle 1
Open Access: The Conservation Commons promotes free and open access to data,
information and knowledge for conservation purposes.
Principle 2
Mutual Benefit: The Conservation Commons welcomes and encourages participants both to use
resources and to contribute data, information and knowledge.
Principle 3
Rights and Responsibilities: Contributors to the Conservation Commons have full right to attribution for
any uses of their data, information, or knowledge, and the right to ensure that the original integrity of their
contribution to the Commons is preserved. Users of the Conservation Commons are expected to comply,
in good faith, with terms of uses specified by contributors and in accordance with these Principles.
The Principles of the Conservation Commons are in line with
• Principle 10 of the Rio Declaration on Environment and Development: environmental issues are
best handled with participation of all concerned citizens, at the relevant level, and that at the
national level each individual shall have appropriate access to information concerning the
environment that is held by public authorities, and the opportunity to participate in decision-
making processes;
• Article 8(j) of the Convention on Biological Diversity: each Party shall, subject to its national
legislation, respect, preserve and maintain knowledge, innovations and practices of indigenous
and local communities embodying traditional lifestyles relevant for the conservation and
sustainable use of biological diversity;
• Article 17 of the Convention on Biological Diversity: Parties shall facilitate the exchange of
information, from all publicly available sources, relevant to the conservation and sustainable use
of biological diversity, taking into account the special needs of developing countries.
The Conservation Commons Secretariat organised an alliance workshop at the 2008 IUCN World
Conservation Congress (WCC) in Barcelona to address barriers to data sharing. The workshop was
organised in collaboration with Conservation International, Global Biodiversity Information Facility, IUCN,
National Geographic Society, The Getty Research Institute, The Nature Conservancy, and UNEP World
Conservation Monitoring Centre.The purpose of this workshop was to draw attention to the barriers faced
by the conservation community which limit access to biodiversity data and information, and to identify
efforts to collectively address these challenges.
See www.conservationcommons.org for more information.
In practice, lack of trust among parties emerged as a significant barrier to exchange of biodiversity
information at the site level. Local researchers feel that they are usurped by outside agencies and foreign
researchers who access their knowledge and publish an analysis of it quickly, sometimes without due
22
credit for their efforts. There is thus great sensitivity about sharing data.
Some data was known to exist which was gathered with public funds.
Such data can be held on for several years without being made widely
available. Appropriate credit for authors in publications with wide
circulation is one incentive which can draw data from sources and the
prospect of having data well-presented and prominently displayed. In
the Okavango case study, production of the freshwater biodiversity
profile and association with the prominent lead author served as an
incentive to draw available data from researchers. The prospect of
having the book co-published between IUCN and the University of
Botswana was an incentive which generated great enthusiasm. The
lead author of the Okavango profile was able to access data which was
not previously available in the public domain for publication.
7. Understand incentives for academic participation in development
work.
Academics play a key role in the development of their (native and host)
countries. This role is most often emphasised in a developing country
context. As individuals, academics may have more or less incentive
beyond personal concern to contribute to development and
conservation. The Okavango Research Centre was initially formed with
a public mandate (see Box 5 at left). However, its placement within the
University structure meant that academic staff were not previously
being adequately incentivised through performance reviews to focus on
research and publication at an academic levelWhile applied research –
for example in the context of the ODMP – does take place, academic
staff time had not previously been specifically allocated for
development or conservation work. Geographic location is also an
issue – the research centre is physically removed from the Delta’s main
town and any stakeholders who do not have access to a private
vehicle. Access to and exchange of scientific results with government
and other stakeholders has not been structurally imbedded into the
modus of operation of government agencies or the research centre –
although in terms of HOORC this is in the process of changing radically
with a new Centre Director. .
Application of data collected to environmental actions through support
for lobbying, public outreach, and practical efforts should also be
rewarded during staff review. The Senior Librarian of HOORC has
sponsored an award for staff who share their knowledge with the wider
community. The Moabi Wa Kitso Award for Knowledge Sharing for the
Okavango Delta is awarded on behalf of HOORC's Library to annually
recognise a person who has made a significant contribution to sharing
of knowledge for the benefit of the Okavango community. Publication of
their results in the Okavango book was one incentive for academics to
contribute to development work. Similar initiatives should be pursued to
Box 5: Origins of the Okavango Research
Centre (ORC)
The origins of the University of Botswana ORC
lie with a government dredging project which
the Department of Water Affairs attempted to
launch in 1991. The project was to deepen,
widen and realign some river bends by
dredging and building bunds. The intention
was to improve the river's flow, enable it to fill
a proposed reservoir in Maun, thus providing
a more reliable and increased water supply to
the district.
A national and international furor arose over
the project. Many residents felt they had not
been adequately consulted; others said they
did not believe it would work, having seen
previous bunding projects fail. Many believed
it would bring a loss of natural resources such
as fish and reeds; others expressed concern
about increased health risks. Local and
regional NGOs and international
environmental organisations such as
Greenpeace protested the plan, and strongly
lobbied the Botswana government to
reconsider. A comprehensive Environmental
Impact Study was carried out by IUCN, which
reported a number of drawbacks to the
project, including environmental damage. the
Botswana government decided to stop the
project.
A major and very positive upshot of the
controversy, however, was Government's
realisation that it lacked sufficient background
knowledge and an adequate scientific base to
formulate policy and management decisions
on the Delta. Government also realised that
an impartial body was needed to monitor
developments in the Delta.
The idea to start a research centre focusing on
sustainable utilisation of the Okavango's
resources was floated. The University of
Botswana, through the Faculty of Science,
expressed interest; and eventually
Government took the decision to create a
research centre as a part of the national
university.

encourage academic support for environmental monitoring, reporting and outreach as part of the core
work of the Centre.
8. Be creative in the design of communication tools.
Information about the freshwater biodiversity of the Delta was already available in reports and academic
papers, but these tools were not necessarily reaching decision-makers. The Okavango case study saw a
potential niche where the project could add value. The USAID and SIDA-funded Okavango River: Flow of
a Lifeline book (Mendelsohn and el Obeid 2004) can be found on the desk or shelf of most decision-
makers and nearly all policy-makers in the Delta, and widely throughout all of the basin countries. The
reach of that book was unlike that which any academic publication or even magazine article would be
likely to have. The idea to produce a similar product with a distinct focus on freshwater biodiversity came
from the evident reach of the Flow of a Lifeline, in combination with the long-standing plan of HOORC and
others to produce an annual ‘State of the Delta’ report book. This product met several needs among
partners in terms of improving the visibility of relevant research, and stimulating interest in the future
results of the monitoring programme. HOORC produces fact sheets to try to get through to people at all
levels, some of which are scheduled to be translated into Setswana.
There are many ways to reach decision makers with information. The recommendation out of the
Okavango case study experience is to identify what has worked previously and interpret creatively to
meet identified gaps in communication. Such communication products may not have the depth of
information available in the academic material but do stimulate a demand for more and updated sources
of information and can have a significant impact.
Adaptive implementation
9. Be realistic about the capacity and motivations for each stakeholder group to contribute to
monitoring.
Many long-term monitoring programmes involve stakeholders in the sampling of an area through a
structure programme of training and support. The South African River Health Programme is an example
of where this has worked very well. The Okavango Delta’s proposed long-term monitoring programme,
however, relies heavily on the efforts of tourism operators to conduct most of the field sampling for
chemistry and macro-invertebrates. One reason for the shift in proposed responsibility is the evident
capacity restrictions of DWA and HOORC. Other driving rationales behind this shift is that the operators
have available staff, are already located in the Delta, have a business incentive to ensure long-term
conservation of the Delta, and given the availability of resources, should play a greater stewardship role
in the Delta’s management. It has been proposed that contributions to and results from monitoring efforts
are reflected as a milestone linked to the renewal of operators’ lease agreements. A Biokavango
consultancy on lease agreements is proposing such a methodology which could be adopted.
In practice, tourism operators are engaged in business, and must by necessity concentrate on providing a
service to their guests. Human resources are often already stretched to capacity with core tourism duties.
Furthermore, if monitoring targets and results are linked to lease renewals, it is unlikely that any operator
would report negative change - the reliability of the resulting data would therefore be questionable.
Although there are many good rationales behind the contribution of tour operators to the monitoring
24
programme, the overall approach seems as yet inadequately thought through. Stakeholders can play a
key role in long-term monitoring programmes, but the designers of these programmes need to be realistic
about how stakeholders can contribute. A strong central body (recall recommendation 3) is still necessary
to maintain quality control of the data. The Department of Water Affairs (DWA) and HOORC can play that
role by sampling at additional locations independent of tour operators. This is the way forward now
proposed.
10. Recognise where need exists for external support.
The Okavango Delta today is relatively pristine, partly as a result of very limited development in northern
Botswana, as well as in upstream countries, and the nature of its economy which is to a large degree
based on ecotourism. Given reasonably good ecological conditions and few actors competing for the
resource, the development of appropriate monitoring tools to start a record of the Delta from these
baseline conditions is essential in the light of increasing tourism and resource use (plus climate change
impacts) in the future. While biomonitoring tools are evidently valuable over a long-term, and to maintain
a record from baseline conditions would yield rich information, groups within the Delta are not
immediately investing in this process. Though the Darwin project (described in Part 3, Section A) is
assisting in the scientific components of this process, the ODMP has little momentum for preventive
interventions at this time.
The Okavango Delta demonstrates a case where the national economic dependence on a wetland
resource is actually quite low. Tthere is instead a heavy dependency in terms of poor people and tourist
commitments. While there is a growing push for nationalisation of the tourism industry, few educated
Batswana are taking up available government grants to establish tourism business and several
businesses in nationalised sectors (Class C mobile safari licenses) have no citizen buyers. Even when
calculating tourism satellite accounts, the Delta is not such a major earner for Botswana when compared
to mining. Diamonds alone account for fully one third of the nation's GDP, over 90% of earnings from
exports, and 50% of government revenues. However, low economic dependence on the Delta has had
the positive attribute that it remains in near-pristine condition.
This presents the difficulty of putting conservation on the political agenda when problems are not yet
acute. Prevention is better than cure is sometimes even difficult in the health sector, let alone the
conservation sector.
Many of the critical partners in the Delta’s conservation are in the upstream countries. Regional NGOs
exist which are concerned about the state of the Delta; for example, the Namibia Nature Foundation,
Desert Research Foundation of Namibia, and the Association for Environmental Conservation and Rural
Development (ACADIR) in Angola. Combined with additional external support, these organisations can
add considerable support and capacity to local efforts led by, for example, the Kalahari Conservation
Society. Since the international community is concerned about conserving the Delta, it needs to support
these NGOs and encourage the development of local civil society groups. Without external support, the
opportunity to conserve the Delta in its intact state could be lost within a generation or less.
Proposals for external conservation funding and technical aid should be considered. International
conservation groups can fill this gap through: technical support for better valuation of the resource (e.g.,
for global biosphere, natural capacity and existence values), improved natural resource accounts and
scenario modeling tools, and creative conservation financing tools such as payment for carbon offsets.
Similar recommendations could apply to other cases where local dependence on a resource is low.
25
11. Be willing to adapt to changing circumstances in order to reach project objectives.
The Okavango Delta case study had a set of project activities which had been negotiated and designed
during a planning phase. In subsequent (interim, pre-implementation and early implementation) periods,
some circumstances changed, other projects had addressed some components of the proposed study,
institutional capacity in the proposed host organisation was found to be insufficient, and some
assumptions or preconditions for project success (e.g., that a long-term monitoring programme would be
underway led by ODMP and DWA) had not materialised within the timeframe as originally envisaged.
The first mechanism for getting biodiversity information into development planning was the monitoring
programme, and IUCN’s dataset was in fact taken up in the design of the OKAS. This first phase of the
case study will have a long-term impact. The second mechanism was the Okavango freshwater profile,
and will have the more immediate impact of getting freshwater biodiversity information on the desks of
decision-makers. By developing the second mechanism, the Okavango book, additional benefits were
achieved which will strengthen the development of the long-term monitoring programme and ensure wide
awareness of freshwater biodiversity in the Delta.
In the case of the Okavango case study, benefits were obtained by revising the activities planned to meet
the projects desired results and objectives, rather than continuing to carry out the activities when
circumstances had changed which would have resulted in sub-optimal outcomes. A more detailed
overview of the project, the stages it went through, what changes were made, and what the outputs and
impacts were can be found in Part 3.
Part 3: Case-specific experience and lessons learned
The Okavango Delta demonstration site was one of four case studies across Africa aiming to get
decision-makers to use freshwater biodiversity information in the process of planning development. The
Okavango Delta site used the mechanisms (or entry points) of a long-term water quality monitoring
system and a book to realise its goal. Broader lessons on the process of getting biodiversity information
used in development planning can be drawn from this pilot experience. This section provides a more in-
depth analysis of implementation in the Okavango case study, first through a review of the activities
conducted (Section A) and then a discussion of lessons learned (Section B).
Section A: Activities of the Case Study
Planning and Design Phase (2005-07/2007)
The proposal for the Okavango Delta demonstration site emerged during the formulation of the Okavango
Delta Management Plan (ODMP) in 2005. The Chief Technical Advisor to ODMP identified the need for
improved freshwater biodiversity information to complement the proposed monitoring work which would
inform adaptive management of the Delta. At the IUCN pan-African project Steering Committee meeting a
representative of the (then-planned) GEF-funded Biokavango project fleshed out details of the proposed
case study, which would occur in parallel to the establishment of the monitoring programme. The “value
added” of the IUCN input at the site scale was to incorporate globally significant biodiversity criteria into
26
the monitoring work, meeting the GEF project’s need to address “incremental benefits” of global
conservation through their project.
The case study shared a staff coordinator at HOORC with the University College London DEFRA Darwin
Initiative funded project, “Monitoring and Simulating Threats to Aquatic Biodiversity in the Okavango
Delta.”
Two other projects were ongoing at HOORC with complementary objectives - the Biokavango Project
(www.orc.ub.bw/biokavango), and the Darwin project (www.orc.ub.bw/projects/darwin.html). The planned
outputs which were common to the three projects were:
(1) An overview of baseline information on freshwater biodiversity in the Delta,
(2) Development of indices of biological integrity (IBI) or similar ecosystem health assessment
tool(s),
(3) Piloting of a long-term water quality monitoring programme towards better decision-making
for implementation of the Okavango Delta Management Plan (ODMP), and
(4) Capacity building and training for biological monitoring (with different emphasis).
The stages of the project are now outlined and discussed in more detail.
Implementation Phase 1 ((07/2007 – 07/2008)
The first phase activities of the IUCN case study were:
1. An exchange of information on the aquatic freshwater biodiversity of the Delta through an
Okavango Freshwater Biodiversity Experts Meeting (October 2007);
2. Identifying information gaps which were filled through partners’ field surveys within the Delta;
3. Support for training to targeted groups in monitoring water quality through the use of bio-
indicators through the production of a training video;
4. Provision of data for the development of an Index of Biotic Integrity (the OKAS) upon which a
long-term programme for monitoring water quality will be based;
5. Support provided to the implementation of a long-term water quality monitoring programme,
through coordinating existing initiatives; and
6. Documentation of the process through which basic biodiversity information has been integrated in
the development of a long-term programme for monitoring water quality.
These individual activities are discussed in more detail.
Activity 1: Information Exchange and Freshwater Experts meeting
The Okavango Freshwater Biodiversity meeting was held from 24-27 October 2007. The meeting brought
together invited experts from the IUCN Southern African Freshwater Biodiversity Assessment and the
South African River Health Programme to interact with local natural resource managers.
Numerous sessions occurred over the four-day meeting to:
• Indicate and ensure government and partner support for the meeting, which is critical to having
recommendations taken up;
• Obtain detailed overviews of information available in all taxa of interest;
27
• Exchange information and consider different interfaces in a Geographic Information Systems
(GIS) and data management session;
• Identify gaps in the data and clarify additional information gathering necessary through field
surveys;
• Present an overview of bio-monitoring programme design theory and practice, with intervals for
interaction on issues of note for the Delta;
• Present long-term monitoring (government, HOORC and private sector represented) and discuss
how to better coordinating these initiatives;
• Enable ODMP to propose how bio-monitoring can best xtox assist in their decision-making
processes;
• Offer technical recommendations by the taxonomic group experts on the design of the monitoring
programme; and
• Collaborate in informal sessions on ongoing and planned initiatives of relevance.
The gathered experts felt that a vision for the biomonitoring programme needs to be more integrated and
work as a cohesive system. It is very possible to produce a useful programme with scarce capacity and
resources if the overall monitoring concepts and mechanisms are well-designed (Day 2007). The experts
recommended a balance in the intention of the effort as to whether the concern is for biotic integrity and
biodiversity versus physical changes in the environment (which could be addressed using different
methods). Indices of biological integrity are useful for fish and macro-invertebrates, but indices for aquatic
plants are hotly debated in terms of their efficacy. Capacity building and data warehousing are critical
components of sustainability of the programme. The availability of reference sites which can demonstrate
unimpaired, or “controlled” portions of the Delta’s different habitats is complicated by the integrated nature
of the Delta’s ecology. A reference collection of samples, therefore, is particularly critical for the Delta.
The “upside down” (neck to surface) flow and potential for “backwashing” (reverse flow) from downstream
Lake Ngami indicates there may not be reference or control sites in the event of flow alteration or
incidence of pollution.
28
One key agreement from the workshop was that a baseline "reference state"
would be preferable to "reference sites" as a key component of the monitoring
programme. This is important for the case study as it demonstrates the useful
application of the project’s Phase 1 Baseline Biodiversity Assessment
(Darwall et al) to site-level monitoring. The IUCN biodiversity data set is going
to be of direct practical use in the monitoring programme. A product of the
expert discussion was the review of how useful and complete are the IUCN
Phase 1 data sets; most were thought to be very comprehensive. Point
locality data (missing for plants) should also be collated whenever possible as
simple range maps (as produced in most of the other species assessments,
e.g. amphibians) are not nearly as useful for on-the-ground application.
Two studies which are known to exist and from which the databases would benefit include:
o Aquatic Rapid Assessment (AQUARAP) 2 – Feb 2003 - Low water survey. Funded by
Conservation International. Described in Dallas & Mosepele 2007.
o Spatial distribution of aquatic invertebrates in the Okavango Delta. WARFSA-funded Jan 2005 to
Jan 2006. Described in Dallas et al 2007.
Both of these data sets comprise part of the Biokavango project’s monitoring consultant’s data and
literature review deliverables. Thus, all available species-level data WILL be included in the IBI
development (a key objective of the IUCN project), if not yet in ODIS and the IUCN database. We hope
there will be an ongoing exchange of information between the two databases to ensure both are kept
current.

Activity 2: Field Surveys
Field surveys were planned to fill identified gaps in knowledge of the Okavango’s freshwater biodiversity.
The surveys which occurred over the course of the project are reviewed below according to taxa: fish,
macro-invertebrates (including molluscs and odonates), and aquatic plants (including algae and
macrophytes). Given the fixed nature of the IUCN project schedule and remote location of the Delta for
researchers, it was often difficult to coordinate field sampling with other projects (see Table 1: Field
surveys proposed and conducted). It was felt that value could be better added to ongoing work in terms of
coordinating this data to a central source.
The ORC has hosted an Okavango Delta Information System (ODIS) database since 2005, which had not
been updated since its first release. ODIS has not been used actively since the development phase of the
ODMP. An updated and more dynamic online tool is proposed to collate data in a central store. As many
researchers of the Okavango are located in South Africa and abroad, this tool should be online and allow
researchers to input their data remotely. Potential risks of this approach for the research centre are
acknowledged. However, HOORC GIS staff are often chasing data which is known to exist but cannot be
released by researchers or government departments, or researchers cannot easily share it. A
comprehensive database would ensure that everyone, in line with the Principles of the Conservation
Commons, could access and use available data. An updated ODIS would also allow data to be
appropriately credited to its author (thereby increasing buy-in), and explain terms of use where
appropriate as some are unwilling to share data if it can be published prior to the author’s opportunity to
do so. There is also plant work being undertaken by researchers Roger and Alison Heath in conjunction
with Kew Gardens and the Biokavango project.
Table 1: Field surveys proposed and conducted
Taxa Status of addressing information gaps
Fish The South African Institute for Aquatic Biodiversity (SAIAB) was scheduled to conduct fish
surveys throughout the ‘panhandle’ region of the Delta under contract with the Biokavango
project. The IUCN case study discussed with SAIAB the possibility of extending their visit to
areas where information gaps were identified, e.g., south of Chief’s Island. The SAIAB team,
was in favour of the idea. However, the Biokavango contract for the fish survey had not been
finalised. It is still unclear when and if the survey will go ahead, and thus the opportunity for the
IUCN project to coordinate on the areas where information gaps exist has passed.
Macro-
invertebrates
The Biokavango project will fund further field sampling of the Delta in 2008 and 2009, to be
conducted by the University of Cape Town’s Freshwater Consulting Group. This group also led
the WARFSA study (high and low water sampling) and the macro-invertebrate component of the
second AquaRAP. Two of four sampling visits had been completed at the time of writing.
The Darwin project has also completed sampling of macro-invertebrates over two years during
four field visits and ongoing work of a locally-funded MSc student. Their data will be incorporated
into the design of Biokavango the macro-invertebrates field study.
Plants A HOORC staff on sabbatical has collected a great deal of field data on aquatic plants for his
PhD.
Combined with the dataset gathered by the Darwin project, there is sufficient information already
available to develop an index of biological integrity (Murray-Hudson, personal communication).

Activity 3: Training
Training sessions (led by Biokavango and Darwin) occurred partly at a different timescale to this project
but one event by each project overlapped. The IUCN coordinator provided assistance for advertising,
organisation, and production of a training video. The Biokavango project macro-invertebrate monitoring
training was attended by HOORC lab assistants, government officials and tour guides. The macro-
invertebrate monitoring programme at present is premised on the idea that the guides will carry out the
monitoring. Part of the Biokavango consultant’s assignment is to determine whether or not the guides will
be capable of carrying out the collection and identification of samples at family level.
The guides and other participants expressed difficulty in the identifications and requested perhaps to use
common names or some other methods to make the identifications easier. As there is no staff at HOORC
sufficiently trained in macro-invertebrate monitoring to supervise the programme and provide reliable
quality control, it is doubtful that a reliance on tour operators to conduct the monitoring can be effective. It
would be preferable to ensure first that sufficient capacity exists in HOORC to oversee and support the
programme prior to training tour guides to conduct the monitoring. We propose that guides collect the
samples and trained staff in HOORC identify samples and do the analysis. This approach would deal with
the problems of guides identifying things correctly and would also ensure a degree of independence
between the sampling and analysis (to avoid any conflict of interest). This is part of new initiatives
coming under the next National Development Plan.
The South African River Health Programme used a phased approach in establishing their monitoring
programme in each province of South Africa. Those involved in collecting and identifications as well as
quality control and supervision are certified with a recognised accreditation which must be updated at
regular intervals to ensure knowledge is up-to-date. Such an accreditation should be developed in order
to ensure capacity to carry out the programme to a high quality is in place. If the quality of the data
collected is poor, it will be of no use in providing any indication about water quality or wetland health.
Given high personnel turnover in the Delta, strong sustainability concerns regarding the value of face-to-
face training also became evident. The IUCN project added value through the production of a training
video (available at HOORC) in partnership with the Biokavango project’s ongoing macro-invertebrates
training. Sustainable training tools such as videos and manuals can assist to reduce cost of training a
larger number of people, improve the consistency of hand-over among staff assigned to monitoring, and
help to reinforce information gained during the hands-on training session. This strategy has been adopted
by DWA for the Salvinia molesta training. In combination with an accreditation programme (which could
be delivered partly online), these tools could ensure high quality and sustained capacity for monitoring in
the Delta.

Activity 4: Develop Index of Biological Integrity
IBIs have made great advances over the past ten years, especially in the selection and testing of metrics
and indices. Before an index can be built and tested, the metrics need to be carefully selected to meet
varying objectives (Day 2007). Most approaches today start from a list of dozens of potential metrics and
then use a systematic process to eliminate those metrics that do not meet certain criteria. In the case of
the Okavango Delta, Okavango Scoring System (OKAS), is based on the well-developed South African
Scoring System (in its fifth iteration, see Dickens & Graham 2002) version and is currently being tested by
the Biokavango project.

Activity 5: Implement the long-term monitoring programme
The fifth activity involves actually implementing the proposed monitoring, putting the sampling protocol
into action, and collecting data. The design of the programme is critical. Design of a long-term water
quality monitoring programme involves:
• Developing a monitoring schedule and logistical plan;
• Determining where to monitor;
• Selecting methods and training on these methods;
• Developing the protocols;
• Providing guidelines to manage data quality;
• Identifying who will do the monitoring and analysis;
• Identifying who will analyse the data (probably HOORC academics);
• Deciding what kind of indicators will be useful for decision-making;
• Determining how the materials will be utilised in planning; and
• Planning for the development of outputs, e.g., a state of the Delta report (Silk and Ciruna 2005).
Initially the Department of Water Affairs had the mandate to lead the monitoring programme with ODMP,
but HOORC later absorbed that responsibility. The Biokavango project has in practice led the
establishment of the programme as it has resources and funding for equipment and consultancies. An
overall vision however, addressing the steps above, has not yet been elaborated. A clear vision for why
the monitoring should take place and for how data would be utilised. A champion within a permanent
institution needs to be identified in order to lead the process of developing the monitoring programme and
seeing it through from design, data collection to influencing decision-makers. The IUCN coordinator
played a role within HOORC to collate the monitoring activities which are ongoing and set targets for
future monitoring activities.
Activity 6: Document the process
The process of trying to get freshwater biodiversity mainstreamed into development planning is of interest
to others trying to undertake similar projects or a long-term effort of utilising biodiversity datasets at site
level. Thus, a major component of the demonstration site was to record this process and share lessons
learned and good practices. The project was documented through a number of modalities: a weekly
“Okavango Update” to the IUCN Project Manager and HOORC supervisor; minutes of weekly
coordination meetings with the Biokavango project circulated to all working on relevant matters, which
served to coordinate the freshwater biodiversity projects in HOORC; weekly meeting with the HOORC
Environmental Monitoring lead to coordinate activities with the ongoing work of HOORC; semi-annual
technical reports; and other one-off reports such as the Joint Projects Document and workshop reports.
An off-line project wiki (user-modified page often used for collaboration and knowledge management) was
later developed to track project issues in order to maintain a single documentation of all issues
encountered (see Figure 12). The Good Practice Guidelines document forms one of the project
deliverables, and intends to summarise the aforementioned sources into a readable yet comprehensive
source.
36
Figure 12: Off-line project wiki was used to record implementation
Project management tools from the PRojects In a Controlled Environment (PRINCE2) methodology were
also utilised to manage and monitor the project. Some outputs of this are useful to report on the
processes of the case study. A Product Breakdown Structure (available on request) indicating
dependencies between the IUCN case study activities and other partners was prepared. Risk monitoring
(see Figure 13) was also influential in understanding the potential success of the case study in reaching
its objectives. Like every project, the Okavango Delta demonstration was subject to constant change in its
wider environment and risks which might affect the potential success. The project’s priorities and relative
importance of risks will shift and change over the course of the process.

Steering Committee Meeting & Phase 2 Design
The IUCN pan-African Freshwater Biodiversity Project Steering Committee meeting was held in June
2008 at IUCN in Yaoundé, Cameroon. The demonstration site Coordinator proposed to the project’s
Steering Committee a change in approach. The idea of a freshwater biodiversity profile for the Okavango
Delta was introduced. The Steering Committee agreed that a change in approach would be necessary to
meet the objectives of the case study and to look into the potential of utilising remaining time and funds to
produce a profile of the Delta. It was observed that John Mendelsohn’s previous book, Okavango River,
the Flow of a Lifeline, had been extremely well received, particularly in Botswana and Namibia. That book
had resulted from a SIDA and USAID-funded basin-wide project to share information and had been
enormously for several years after the close of that project. The profile would get available freshwater
biodiversity information on the desks of decision-makers and build anticipation for the results of the
monitoring programme.
The Okavango Delta case study proceeded to re-orient activities in order to deliver the project objectives
through this second mechanism, or entry point, for getting the IUCN dataset used in development
planning. The (as yet untitled) freshwater biodiversity profile of the Okavango will fill a niche among
ongoing work to:
- Get reach decision-makers directly with freshwater biodiversity information;
- Raising awareness among stakeholders and particularly decision-makers about the importance of
freshwater biodiversity;
- Generate understanding about the usefulness of FWBD as an ecosystem health indicator at the
local scale and its global/regional biodiversity importance particularly as human encroachment
and climate change impact other African wetlands;
- Describe the potential threats to the Okavango Delta and methods to reduce these
- Understand how freshwater biodiversity fits with development planning and entry points for it such
as monitoring, Environmental Impact Assessment (EIA) and awareness at the political level, e.g.,
through OKACOM; and
- Piloting a reporting tool for the biological monitoring programme.
Most of the necessary information for the profile was already available in the public domain, collated
through the IUCN Southern African Freshwater Biodiversity Assessment and through academic reports of
surveys funded by Conservation International and WARFSA. The point of the book is simply to make this
information attractive and digestible for the target audience which includes policy-makers, decision-
makers, politicians (including Ministers and Members of Parliament), OKACOM, upriver environmental
agencies and civil society groups, donor agencies, local project administrators, private sector (especially
tourism operators), researchers and students, the media, interested residents, tourists to the Delta, and
others. These partners can then play an advocacy role to ensure that the FWBD is considered in the
development planning process.
Phase 2: Partners in Okavango freshwater biodiversity profile (09/2008-05/2009)
IUCN, HOORC, the Darwin project, the Biokavango project and SAIAB are all now partners in executing
the Okavango freshwater biodiversity profile. John Mendelsohn, lead author of the Flow of a Lifeline, has
been contracted by IUCN as the lead author on the project. Partners are utilising Huddle
(www.huddle.net), an online collaboration tool, to set deadlines, share folders and large documents and
38
eventually for collaborative document editing. At the time of writing2, the author had conducted a field visit
and obtained numerous agreements by HOORC staff (and other people) to contribute in different ways to
the book. Many see the book as a great opportunity to produce an accessible review of the Delta's
biology and functioning. The first run of the book funding by IUCN is targeted to 500 decision-makers in
the basin countries. Subsequent editions will be supported by partners who will ensure that the book
reaches a really wide audience.
Concerns around authorship were revised and researchers are incentivised by publication credits. A
hybrid between academic style publication and general interest publication style of crediting was devised.
It is expected that the writing and revision continue until February or March 2009, followed by professional
layout and printing in April or May of that year. An electronic (PDF) version of the book will be available
for download on the websites of the partners involved.
Ensuring sustainability of the investment (from 2009)
The IUCN case study was designed with sustainability of the EC investment at the scale level in mind.
The IUCN southern African freshwater biodiversity dataset (Darwall et al 2009) has been utilised in the
development of the Delta’s IBI, the OKAS. Thus, it will have a long-term impact through the development
of a long-term monitoring programme. The Okavango freshwater biodiversity profile will have an impact
beyond the lifespan of the project, as well, and likely remain on decision-makers desks for years to come.
Follow-on activities proposed to ensure that the objectives of the case study are strengthened and
ensured into the future. These are:
• To utilise IUCN’s convening power for a visioning exercise with stakeholders on the monitoring
programme and sense of how that information should be utilised, who should do what and what is
realistic, scaling up;
• Long-term funding support to develop a centre for freshwater biodiversity monitoring, with a staff
post dedicated to this endeavour. The centre could be within ODMP, HOORC or affiliated to
these with a development mandate;
• Funding to update ODIS into a dynamic web-based tool with reporting features and the ability to
be user-driven; and
• Relationship development in Botswana since the IUCN country office has closed. Hire a part-time
individual to represent IUCN at local meetings, keep up relationships, support future work, collate
news on relevant topics, and enable future project development.

Part B: Lessons learned
Many lessons were learned in carrying out the process of getting freshwater biodiversity information into
development planning in the Okavango case study. Lessons were learned in the process of designing the
demonstration site interventions, in developing tools and methods for getting biodiversity information
utilised, and in the adaptive management of the implementation process. These are presented bellow
with a brief description, relevance or application in the Okavango case, and link to the recommendation in
Part 2 which the lesson has substantiated.
Lessons for design
1. Smaller projects may need to find a specific niche in order to work very well.

Part 4: Practical guidance for successful interventions in the Okavango
Delta
This section aims to enhance the knowledge of individuals and institutions undertaking similar
conservation efforts in the Okavango Delta. Context is very important: countless projects fail because
they fail to understand the local culture, protocol, politics, stakeholder interests, individual relationships, or
the wider environment of the intervention. The Okavango case study focused on the Delta and was
administered from Maun, at the southern extreme of the Delta’s Boro River channel. A former HOORC
Adjunct Professor gives a useful introduction to the layered interests at play in managing the Delta in light
of its downstream position from Angola and Namibia (see Box 6).
44
Key aspects of the Delta and its biodiversity, economic value and other features can be found elsewhere
in published material. Useful sources of information are:
• The forthcoming profile of the Delta’s freshwater biodiversity (Mendelsohn et al 2009)
• Okavango River: the Flow of a Lifeline (Mendelsohn and el Obeid 2004)
• The Okavango Delta Management Plan, available from the Ramsar Convention Secretariat3
• Publications of the USAID Integrated River Basin Management Project (IRBM)4
• Flow : information for Okavango Delta Planning, the HOORC Library blog5
This section focuses primarily on those insights which can be gained through on-the-ground experience.
The notes below highlight issues which may change in importance over time, but should be considered in
future interventions: language and gender roles, protocol and the culture of consensus, the political
economy of the Okavango Delta, the establishment of regional governance mechanisms, barriers to data
sharing, the impacts of HIV/AIDS on capacity, and regional unrest.

Box 6: Views of the Okavango River
When one speaks of the Okavango River a variety of images come to mind. How one thinks about and values the
resources of that river depend very much on where one sits and what one does while sitting.
For a conservation desk officer located in Berlin or London or Washington, starved of green spaces and horizons,
whose senses are brutally assaulted by late-modern life, the Okavango is both idyllic symbol of the pre-modern and
functional storeroom of the biosphere. For a Motswana, squatting in a Delta reed bed during the high flow season,
collecting reeds or fish, livestock grazing and watering nearby, the river is a life-sustaining artery flowing variably
through a harsh physical environment. For a member of the Department of Water Affairs, sitting in Windhoek,
worrying about dam levels, AGOA-driven development directives and population influx, the river appears primarily
as a factor of production, a resource that must be harnessed if standards of living are to be maintained and
livelihood options improved not only in Windhoek but throughout the central highveld.
The value of the river differs slightly for a member of Botswana’s inner elite – someone in Cabinet, or a Permanent
Secretary perhaps. Well-paid and interested in business opportunities, you are late in recognising the economic
potential of tourism in the Delta region. The river for as long as you can remember has been very far from the cut
and thrust of every day politics in Gaborone, though there was that unfortunate incident some fifteen years ago
when a government proposal to dredge the lower Boro river, upstream of the village of Maun, and transfer water
to Orapa Mine did raise a significant public outcry among residents of Ngamiland. Thus, the tourism sector is
dominated by foreigners – tour operators from South Africa, Australia, England, the United States – and you are
now interested in getting in on the action. The lower Okavango, particularly the Delta, to you is also a factor of
production, but tourism is mainly a non-consumptive, post-industrial service industry.
Of all riparian state and basin dwelling actors, the Okavango resides furthest from the minds of policy makers in
Luanda. Beleaguered for decades by a pernicious rebel movement, UNITA, assisted variously by South Africa and
the United States, you have long been preoccupied with economic and political survival. Moreover, your party and
your interests are very much Luanda and north of Luanda-centred. The oil from Cabinda is your lifeline, not water
from the Cubango and Cuito river systems that ultimately join to form the Okavango. Indeed, there are many rivers
and much water in Angola; the Okavango is of little concern to you. But you do know that your neighbours,
Namibia and Botswana, long allies in the struggles against colonialism, apartheid and more recently war in the
DRC, are very interested in the resources of the Okavango River Basin (ORB). You want to accommodate them, but
you have interests in other river basins shared with Namibia. Perhaps you can use the Okavango as a bargaining
chip for mutual gain. At the same time, as a participating member of the Southern African Development
Community (SADC) in the post-civil war era, you would like to play by the regional rules – although, unsure of what
these mean for your sovereign right to act as a state, you have ratified almost none of the regional protocols.

Language and gender roles
While English is Botswana’s official language, Setswana is the national language. Much daily activity
occurs in Setswana, crucially in terms of negotiation and building informal links. Often key parts of
meetings take place in Setswana or another local language. Have a well trusted local-language speaker
on your team. Despite widespread adoption of English as the official language of government and
business, estimates of the proportion of Batswana who have any knowledge of English range from 35 to
40% (Bagwasi, 2003). Any individuals working in (or planning to work in) Botswana should at least have
familiarity with basic terms and working ability with greetings. This is valuable, and helps build trust, but
does not replace the above. A citizen of Botswana is referred to as a Motswana. The plural of this is
Batswana, and the language of the Tswana people is Setswana. Some of the basic phrases to get started
are available online.
Ikalanga is also widely spoken in academic, government and professional spheres. The Kalanga people,
though representing only 150,000 of Botswana’s population, invest heavily in education and thus are
strongly represented in advanced positions, for example in the management of the Delta. It may also be
worthwhile to invest time learning at least basic greetings in Ikalanga.
Botswana has a predominantly patriarchical culture, where men are assumed to be leaders and parallels
to traditional family life are often drawn. When considering candidates for a position or looking to
leadership in a meeting for example, gender as well as age can be key deciding factors. It is disrespectful
for women to wear trousers in a village. Particularly at a kgotla (public meeting), women must wear long
skirts. Women may be sent home to change or asked to leave the meeting if not attired correctly. Foreign
women may be excused from this rule in a town but it is best to demonstrate respect as best possible and
wear skirts to public events.

Protocol and the culture of consensus
In the workplace, appropriate protocol is of paramount importance and essential to demonstrate proper respect for Botswana’s institutions and senior/high-ranking individuals. The guidance (in Table 2) below reflects general experience.

Table 2: Notes on protocol
Address
Women as “Mma” or “Mme” for highest respect. Address men as “Rra” or “Rre” to
denote highest respect.
Greetings Greetings are very important. Make time to greet everyone in a room.
Titles
Anyone with a PhD is called Doctor, as well as medical doctors.
Meetings
Meetings are opened with prayers.
Budget at least two hours for speeches at the beginning of an open meeting.
Allow sufficient time for comments and discussions, around 50% of the agenda.
Requests,
Invitations
Send letters from the highest individual in an organisation, or as high as feasibly
possible.
Consultation is absolutely critical. The process of discussing to reach consensus is highly valued in
Botswana, with roots in the traditional kgotla system. For important decisions, a kgotla (public meeting),
must be arranged. It should be run by a senior official in concert with the traditional local leaders, and
outcomes are always arrived at by consensus. In fact, it’s a little more subtle than this: the outcome can
often be accurately predicted, even if the path to reaching it cannot. The kgotla does not let everyone
have a hand in making a decision, but in discussing it, and thereby feeling part of it. Anyone at all is
allowed to speak, and no one may interrupt while someone is "having their say". This custom of allowing
everyone their full say is carried over into meetings of all kinds, from discussing a budget to a staff
briefing, and can mean meetings last many hours. It is critical to allow enough time for this process,
because decisions just do not go forward without full support, and any decisions which do are likely to
suffer heavily and probably fail from lack of support.

The political economy of the Okavango Delta
Botswana is under pressure to diversify its economy away from a reliance on mining. Emphasis has
shifted to the tourism industry to provide more jobs and wealth (through ownership) for Batswana. While
the tourism industry has exceeded expectations in terms of environmental management, and some of the
Delta’s camps are world-renowned for environmental performance, it is worth noting the political tensions
that surround tourism development in the Delta. International organisations can easily be seen to be
siding with the largely foreign-owned tourism industry, for example as these companies are celebrated by
international recognition of their environmental initiatives and leadership.
A local view is that Delta tourism is “enclave” tourism, or “internal colonialism.” As described by a HOORC
researcher, it is held that, “socio-economic benefits such as better paying jobs, particularly those in
management, are occupied by expatriates. The dominance of the industry by foreign investors and the
non-local investment [has] reduced control over local resources … the loss of local autonomy is certainly
the most negative long-term socio-cultural effect of tourism in a destination area. A local resident may
also suffer a loss of sense of place, as his/her surrounding is transformed to accommodate the
requirements of a foreign-dominated tourism industry. Interviews with the local people in the Okavango
indicate that there is a general assumption that the Delta has been taken from them by government and
given to foreign tour operators” (Mbaiwa 2005). It is important to be aware of the strong feelings
presented by tourism development, and particularly the apparent linkages between international NGOs
and ecotourism operations. Internal correspondence from safari operations has been leaked to the
national media which demonstrate racism by safari operators. A balanced approach working in the Delta
should be taken where international conservation organisations do not work with tour operators to the
apparent exclusion of local groups.

Competitiveness
The establishment of regional governance mechanisms
The potential impact of regional governance mechanisms is yet to be truly tested. As Angola and Namibia
are still charting out their development paths, the nature of the pressure on the Delta is still unclear to
some degree and the effectiveness of these institutions cannot yet be determined. The establishment of
the OKACOM and Kavango-Zambezi Transfrontier Conservation Area secretariats in Maun mean that
conservation work for a very wide area will be concentrated in one location. These institutions comprise
governance mechanisms for the Okavango, Zambezi and the Kwando/Linyanti/Chobe systems, the “four

corners” tourism region (the point at which Botswana, Namibia, Zambia and Zimbabwe meet, around
Impalila Island), and Angola’s rivers (as the source of most of the regions’ rivers). The establishment and
application of these governance mechanisms are thus of great interest to the whole region’s
conservation.

Media, and Jornal de Angola (in Portuguse only) for details on emerging developments13
Barriers to data sharing
Data sharing and collation of available has proved to be a difficult issue in the Delta and the basin
countries. Johannessen’s (2007) review of this issue, through interviews with partners, found that lack of
trust in the Delta community is a significant barrier to data sharing and developing common
methodologies in data collection. Soderstrom et al’s (2005) recent experience in the basin found:
Even in the seemingly cut and dry task of assembling data into a searchable database,
trust between parties is of paramount importance. Data is perceived as power and
sharing data can be perceived as relinquishing power. Data requires significant
investment to collect and maintain. Data is the foundation for specialised knowledge and
many researchers, organizations, and other groups base their reputations and self-worth
on the specialised knowledge they provide. To share data can be interpreted as risking
one’s advantage.
Incentives to draw out data need to be explicitly developed for data collaboration to work.
Sources for further guidance:
- The recommendations of Good Practice Guidelines contain some tools (prominent publication,
awards) which have worked in the Delta
- User-driven and -owned monitoring tools like Namibia’s Event Book system place incentives up-front
at the collection stage: users share the data because they benefit from improved management. See
Stuart-Hill et al (2006) for guidance.
The impacts of HIV/AIDS on capacity
Botswana has one of the world’s highest rates of HIV infection. Prevalence fell from 36% in 2001 to 32%
in 2006, though largely due to mortality impacts. Prevention efforts have begun to work, though, and HIV
prevalence among women in Botswana between the ages of 15-19 and 20-24 has fallen to 17.8% and
30.6%, respectively, the lowest levels since 1992.

Impacts of high HV prevalence on the capacity for conservation work have been documents (e.g., in KCS
2008; Oglethorpe and Gelman 2005) and include:
- The loss of productivity for law enforcement, policy, research, education, tourism, community work
and protected area management;
- Loss of institutional memory;
- Threat to conservation partnerships and modalities;
- Loss of investments into training;
- Diversion of conservation funds to the morbidity and mortality costs associated with AIDS, including
funerals, sick leave, and training for new staff.
Combined other factors such as a lack of succession planning, lack of handover to incoming personnel,
and high turnover and mobility in the Delta’s organisation, investments in training eroded lost at an
astonishing rate. It is critical to design conservation interventions in recognition of these realities. Ideas to
mitigate loss of knowledge focus on investment knowledge management, database of reports, thematic
wikis, videos, etc. HIV/AIDS and Environment Working Groups (HEWGs) have formed in Namibia and
Botswana to address interlinkages between AIDS and environmental sustainability and can provide
detailed advice.

Regional unrest
The crisis in Zimbabwe has a destabilizing effect on the entire southern African region. Botswana’s
Chobe and Ngamiland Districts are frontlines for refugees exiting to through the northern and western
borders. The official number of Zimbabwean refugees according to government statistics in 2007 was
approximately 250,000 - a number which is growing as conditions in Zimbabwe continue to deteriorate
(e.g., the recent cholera outbreak). The crisis could already be diverting the time of government officials in
the region and resources institutions in Botswana.
