I. INTRODUCTION
Past attempts to manage drought and its impacts through areactive, crisis management approach have been ineffective,poorly coordinated, and untimely, as illustrated by the hydro-illogical cycle in Figure 1. The crisis management approachhas been followed in both developed and developing countries.Because of the ineffectiveness of this approach, greater inter-est has evolved in recent years in the adoption of a moreproactive risk-based management approach in some countries(see Chapter 6). Other countries are striving to obtain ahigher level of preparedness through development of nationalaction programs that are part of the United Nations Conven-tion to Combat Desertification (UNCCD) or as part of separatenational initiatives. In part, these actions directly result fromthe occurrence of recent severe drought episodes that havepersisted for several consecutive years or frequent episodesthat have occurred in succession with short respites for recov-ery between events. Global warming, with its threat of an

increased frequency of drought events in the future, has alsocaused greater anxiety about the absence of preparation fordrought, which is a normal part of climate. Other factors thathave contributed to this trend toward improved drought pre-paredness and policy development are spiraling costs orimpacts associated with drought, complexity of impacts onsectors well beyond agriculture, increasing social and envi-ronmental effects, and rising water conflicts between users.
Progress on drought preparedness and policy develop-ment has been slow for a number of reasons. It certainlyrelates to the slow-onset characteristics of drought and thelack of a universal definition. These characteristics (definedin more detail in Chapter 1) make early warning, impactassessment, and response difficult for scientists, naturalresource managers, and policy makers. The lack of a universal

definition often leads to confusion and inaction on the part ofdecision makers because scientists may disagree on the exist-ence of drought conditions and severity. Severity is also diffi-cult to characterize because it is best evaluated on the basisof multiple indicators and indices rather than a single vari-able. The impacts of drought are also largely nonstructuraland spatially extensive, making it difficult to assess the effectsof drought and respond in a timely and effective manner.Drought and its impacts are not as visual as other naturalhazards, making it difficult for the media to communicate thesignificance of the event and its impacts to the public. Publicsentiment to respond is often lacking in comparison to othernatural hazards that result in loss of life and property.
Another constraint to drought preparedness has been thedearth of methodologies available to planners to guide themthrough the planning process. Drought differs in its charac-teristics between climate regimes, and impacts are locallydefined by unique economic, social, and environmental char-acteristics. A methodology developed by Wilhite (1991) andrevised to incorporate greater emphasis on risk management(Wilhite et al., 2000) has provided a set of guidelines or achecklist of the key elements of a drought plan and a processthrough which they can be adapted to any level of government(i.e., local, state or provincial, or national) or geographicalsetting as part of a natural disaster or sustainable develop-ment plan, an integrated water resources plan, or a stand-alone drought mitigation plan. We describe this process here,with the goal of providing a template that government ororganizations can follow to reduce societal vulnerability todrought.
II. PLANNING FOR DROUGHT: THE PROCESS
Drought is a natural hazard that differs from other hazardsin that it has a slow onset, evolves over months or even years,affects a large spatial region, and causes little structuraldamage. Its onset and end are often difficult to determine, asis its severity. Like other hazards, the impacts of drought spaneconomic, environmental, and social sectors and can bereduced through mitigation and preparedness. Because

Drought Preparedness Planning: Building Institutional Capacity 97
droughts are a normal part of climate variability for virtuallyall regions, it is important to develop drought preparednessplans to deal with these extended periods of water shortagein a timely, systematic manner as they evolve. To be effective,these plans must evaluate a region’s exposure and vulnera-bility to the hazard and incorporate these elements in a waythat evolves with societal changes.
The 10-step drought planning process developed by Wil-hite (1991) was based largely on interactions with many statesin the United States, incorporating their experiences and les-sons learned. This planning process has gone through severaliterations in recent years in order to tailor it to specific coun-tries or subsets of countries (Wilhite et al., 2000). It has alsobeen the basis for discussions at a series of regional trainingworkshops and seminars on drought management and pre-paredness held throughout the world over the past decade.With the increased interest in drought mitigation planningin recent years, this planning process has evolved to incorpo-rate more emphasis on risk assessment and mitigation tools.
The 10-step drought planning process is illustrated inFigure 2. In brief, Steps 1–4 focus on making sure the rightpeople are brought together, have a clear understanding ofthe process, know what the drought plan must accomplish,and are supplied with adequate data to make fair and equi-table decisions when formulating and writing the actualdrought plan. Step 5 describes the process of developing anorganizational structure for completion of the tasks necessaryto prepare the plan. The plan should be viewed as a process,rather than a discrete event that produces a static document.A risk assessment is undertaken in conjunction with this stepin order to construct a vulnerability profile for key economicsectors, population groups, regions, and communities. Steps6 and 7 detail the need for ongoing research and coordinationbetween scientists and policy makers. Steps 8 and 9 stressthe importance of promoting and testing the plan beforedrought occurs. Finally, Step 10 emphasizes revising the planto keep it current and evaluating its effectiveness in the post-drought period. Although the steps are sequential, many ofthese tasks are addressed simultaneously under the leader-ship of a drought task force and its complement of committees
DK2949_book.fm Page 97 Friday, February 11, 2005 11:25 AM
98 Wilhite et al.
and working groups. These steps, and the tasks included ineach, provide a “checklist” that should be considered and maybe completed as part of the planning process.
III. STEP 1: APPOINT A DROUGHT TASK FORCE
A key political leader initiates the drought planning processthrough appointment of a drought task force. Depending onthe level of government developing the plan, this could be thepresident or prime minister, a provincial or state governor, ora mayor. The task force has two purposes. First, it supervisesand coordinates development of the plan. Second, after theplan is developed and during times of drought when the planis activated, the task force coordinates actions, implements

mitigation and response programs, and makes policy recom-mendations to the appropriate political leader.
The task force should reflect the multidisciplinary natureof drought and its impacts, and it should include appropriaterepresentatives of government agencies (provincial, federal)and universities where appropriate expertise is available. Ifapplicable, the governor’s office should have a representativeon the task force. Environmental and public interest groupsand others from the private sector can be included (see Step3), as appropriate. These groups would be involved to a con-siderable extent in the activities of the working groups asso-ciated with the Risk Assessment Committee discussed in Step5. The actual makeup of this task force would vary consider-ably, depending on the principal economic and other sectorsaffected, the political infrastructure, and other factors. Thetask force should include a public information official that isfamiliar with local media’s needs and preferences and a publicparticipation practitioner who can help establish a processthat includes and accommodates both well-funded and disad-vantaged stakeholder or interest groups.
IV. STEP 2: STATE THE PURPOSE AND OBJECTIVES OF THE DROUGHT PLAN
As its first official action, the drought task force should statethe general purpose for the drought plan. Government offi-cials should consider many questions as they define the pur-pose of the plan, such as the
• Purpose and role of government in drought mitigationand response efforts
• Scope of the plan• Most drought-prone areas of the state or nation• Historical impacts of drought• Historical response to drought• Most vulnerable economic and social sectors• Role of the plan in resolving conflict between water
users and other vulnerable groups during periods ofshortage
DK2949_book.fm Page 99 Friday, February 11, 2005 11:25 AM
100 Wilhite et al.
• Current trends (e.g., land and water use, populationgrowth) that may increase or decrease vulnerabilityand conflicts in the future
• Resources (human and economic) the government iswilling to commit to the planning process
• Legal and social implications of the plan• Principal environmental concerns caused by drought
A generic statement of purpose for a plan is to reducethe impacts of drought by identifying principal activities,groups, or regions most at risk and developing mitigationactions and programs that alter these vulnerabilities. Theplan is directed at providing government with an effectiveand systematic means of assessing drought conditions, devel-oping mitigation actions and programs to reduce risk inadvance of drought, and developing response options thatminimize economic stress, environmental losses, and socialhardships during drought.
The task force should then identify the specific objectivesthat support the purpose of the plan. Drought plan objectiveswill vary within and between countries and should reflect theunique physical, environmental, socioeconomic, and politicalcharacteristics of the region in question. For a provincial,state, or regional plan, objectives that should be consideredinclude the following:
• Collect and analyze drought-related information in atimely and systematic manner.
• Establish criteria for declaring drought emergenciesand triggering various mitigation and response activ-ities.
• Provide an organizational structure and delivery sys-tem that ensures information flow between and withinlevels of government.
• Define the duties and responsibilities of all agencieswith respect to drought.
• Maintain a current inventory of government programsused in assessing and responding to drought emergen-cies.
DK2949_book.fm Page 100 Friday, February 11, 2005 11:25 AM
Drought Preparedness Planning: Building Institutional Capacity 101
• Identify drought-prone areas of the state or region andvulnerable economic sectors, individuals, or environ-ments.
• Identify mitigation actions that can be taken toaddress vulnerabilities and reduce drought impacts.
• Provide a mechanism to ensure timely and accurateassessment of drought’s impacts on agriculture, indus-try, municipalities, wildlife, tourism and recreation,health, and other areas.
• Keep the public informed of current conditions andresponse actions by providing accurate, timely infor-mation to media in print and electronic form (e.g., viaTV, radio, and the World Wide Web).
• Establish and pursue a strategy to remove obstaclesto the equitable allocation of water during shortagesand establish requirements or provide incentives toencourage water conservation.
• Establish a set of procedures to continually evaluateand exercise the plan and periodically revise the planso it will stay responsive to the needs of the area.
V. STEP 3: SEEK STAKEHOLDER PARTICIPATION AND RESOLVE CONFLICT
Social, economic, and environmental values often clash as com-petition for scarce water resources intensifies. Therefore, it isessential for task force members to identify all citizen groups(stakeholders) that have a stake in drought planning andunderstand
their interests. These groups must be involvedearly and continuously for fair representation and effectivedrought management and planning. Discussing concerns earlyin the process gives participants a chance to develop an under-standing of one another’s various viewpoints and generate col-laborative solutions. Although the level of involvement of thesegroups will vary notably from location to location, the powerof public interest groups in policy making is considerable. Infact, these groups are likely to impede progress in the devel-opment of plans if they are not included in the process. Thetask force should also protect the interests of stakeholders who
DK2949_book.fm Page 101 Friday, February 11, 2005 11:25 AM
102 Wilhite et al.
may lack the financial resources to serve as their own advo-cates. One way to facilitate public participation is to establisha
citizen’s advisory council as a permanent feature of thedrought plan, to help the task force keep information flowingand resolve conflicts between stakeholders.
State or provincial governments need to consider if dis-trict or regional advisory councils should be established.These councils could bring neighbors together to discuss theirwater use issues and problems and seek collaborative solu-tions. At the provincial level, a representative of each districtcouncil should be included in the membership of the provincialcitizens’ advisory council to represent the interests and valuesof their constituencies. The provincial citizens’ advisory coun-cil can then make recommendations and express concerns tothe task force as well as respond to requests for situationreports and updates.
VI. STEP 4: INVENTORY RESOURCES AND IDENTIFY GROUPS AT RISK
An inventory of natural, biological, and human resources,including the identification of constraints that may impedethe planning process, may need to be initiated by the taskforce. In many cases, various provincial and federal agenciesalready possess considerable information about natural andbiological resources. It is important to determine the vulner-ability of these resources to periods of water shortage thatresult from drought. The most obvious
natural
resource
ofimportance is water: its location, accessibility, and quality.
Biological resources
refer to the quantity and quality of grass-lands or rangelands, forests, wildlife, and so forth.
Humanresources
include the labor needed to develop water resources,lay pipeline, haul water and livestock feed, process citizencomplaints, provide technical assistance, and direct citizensto available services.
It is also imperative to identify constraints to the plan-ning process and to the activation of the various elements ofthe plan as drought conditions develop. These constraints maybe physical, financial, legal, or political. The costs associated
DK2949_book.fm Page 102 Friday, February 11, 2005 11:25 AM
Drought Preparedness Planning: Building Institutional Capacity 103
with plan development must be weighed against the lossesthat will likely result if no plan is in place. The purpose of adrought plan is to reduce risk and, therefore, economic, social,and environmental impacts. Legal constraints can includewater rights, existing public trust laws, requirements for pub-lic water suppliers, liability issues, and so forth.
In drought planning, making the transition from crisisto risk management is difficult because, historically, little hasbeen done to understand and address the risks associatedwith drought. To solve this problem, areas of high risk shouldbe identified, as should actions that can be taken to reducethose risks before a drought occurs. Risk is defined by boththe exposure of a location to the drought hazard and thevulnerability of that location to periods of drought-inducedwater shortages (Blaikie et al., 1994). Drought is a naturalevent; it is important to define the exposure (i.e., frequencyof drought of various intensities and durations) of variousparts of the state or region to the drought hazard. Some areasare likely to be more at risk than others. Vulnerability, on theother hand, is affected by social factors such as populationgrowth and migration trends, urbanization, changes in landuse, government policies, water use trends, diversity of eco-nomic base, cultural composition, and so forth. The droughttask force should address these issues early in the planningprocess so they can provide more direction to the committeesand working groups that will be developed under Step 5 ofthe planning process.
VII. STEP 5: ESTABLISH AND WRITE DROUGHT PLAN
This step describes the process of establishing relevant com-mittees to develop and write the drought plan. The droughtplan should have three primary components: (1) monitoring,early warning, and prediction; (2) risk and impact assess-ment; and (3) mitigation and response. We recommended thata committee be established to focus on the first two of theseneeds; the drought task force can in most instances carry outthe mitigation and response function.

The suggested organizational structure for the plan isillustrated in Figure 3.
The committees will have their owntasks and goals, but well-established communication andinformation flow between committees and the task force isnecessary to ensure effective planning.
A. Monitoring, Early Warning, and Prediction Committee
A reliable assessment of water availability and its outlook forthe near and long term is valuable information in both dryand wet periods. During drought, the value of this informationincreases markedly. The monitoring committee should includerepresentatives from agencies with responsibilities for moni-toring climate and water supply. Data and information oneach of the applicable indicators (e.g., precipitation, temper-ature, evapotranspiration, seasonal climate forecasts, soil

moisture, streamflow, groundwater levels, reservoir and lakelevels, and snowpack) ought to be considered in the commit-tee’s evaluation of the water situation and outlook. The agen-cies responsible for collecting, analyzing, and disseminatingdata and information will vary considerably from country tocountry and province to province.
The monitoring committee should meet regularly, espe-cially in advance of the peak demand season. Following eachmeeting, reports should be prepared and disseminated to thedrought task force, relevant government agencies, and themedia. The chairperson of the monitoring committee shouldbe a permanent member of the drought task force. If condi-tions warrant, the task force should brief the governor orappropriate government official about the contents of thereport, including any recommendations for specific actions.The public must receive a balanced interpretation of changingconditions. The monitoring committee should work closelywith public information specialists to keep the public well-informed.
The primary objectives of the monitoring committee are to
1. Adopt a workable definition of drought that could beused to phase in and phase out levels of local stateor provincial, and federal
actions in response todrought. The group may need to adopt more than onedefinition of drought in identifying impacts in variouseconomic, social, and environmental sectors becauseno single definition of drought applies in all cases.Several indices are available (Hayes, 1998), includingthe Standardized Precipitation Index (McKee et al.,1993, 1995), which is gaining widespread acceptance(Guttman, 1998; Hayes et al., 1999; also see
http://drought. unl.edu/ whatis/Indices.pdf
. The trend is to rely on multiple drought indices totrigger mitigation and response actions, which arecalibrated to various intensities of drought. The cur-rent thought is that no single index of drought isadequate to measure the complex interrelationshipsbetween the various components of the hydrologicalcycle and impacts.
DK2949_book.fm Page 105 Friday, February 11, 2005 11:25 AM
106 Wilhite et al.
It is helpful to establish a sequence of descriptiveterms for water supply alert levels, such as “advisory,”“alert,” “emergency,” and “rationing” (as opposed tomore generic terms such as “phase 1” and “phase 2,”or sensational terms such as “disaster”). Review theterminology used by other entities (i.e., local utilities,provinces, river basin authorities) and choose termsthat are consistent so as not to confuse the publicwith different terms in areas where there may beauthorities with overlapping regional responsibili-ties. These alert levels should be defined in discus-sions with both the risk assessment committee andthe task force.In considering emergency measures such as ration-ing, remember that the impacts of drought may varysignificantly from one area to the next, depending onthe sources and uses of water and the degree of plan-ning previously implemented. For example, some cit-ies may have recently expanded their water supplycapacity while other adjacent communities may havean inadequate water supply capacity during periodsof drought. Imposing general emergency measures onpeople or communities without regard for their exist-ing vulnerability may result in political repercussionsand loss of credibility.A related consideration is that some municipal watersystems may be out of date or in poor operating con-dition, so that even moderate drought strains a com-munity’s ability to supply customers with water.Identifying inadequate (i.e., vulnerable) water supplysystems and upgrading those systems should be partof a long-term drought mitigation program.
2. Establish drought management areas; that is, subdi-vide the province or region into more convenientlysized districts by political boundaries, shared hydro-logical characteristics, climatological characteristics,or other means such as drought probability or risk.These subdivisions may be useful in drought man-agement because they may allow drought stages andmitigation and response options to be regionalized.
DK2949_book.fm Page 106 Friday, February 11, 2005 11:25 AM
Drought Preparedness Planning: Building Institutional Capacity 107
3. Develop a drought monitoring system. The quality ofmeteorological and hydrological networks is highlyvariable from country to country and region to regionwithin countries. Responsibility for collecting, ana-lyzing, and disseminating data is divided betweenmany government authorities. The monitoring com-mittee’s challenge is to coordinate and integrate theanalysis so decision makers and the public receiveearly warning of emerging drought conditions.Considerable experience has developed in recentyears with automated weather data networks thatprovide rapid access to climate data. These networkscan be invaluable in monitoring emerging and ongo-ing drought conditions. Investigate the experiencesof regions with comprehensive automated meteoro-logical and hydrological networks and apply theirlessons learned, where appropriate.
4. Inventory data quantity and quality from currentobservation networks. Many networks monitor keyelements of the hydrologic system. Most of these net-works are operated by federal or provincial agencies,but other networks also exist and may provide criticalinformation for a portion of a province or region.Meteorological data are important but represent onlyone part of a comprehensive monitoring system.These other physical indicators (soil moisture,streamflow, reservoir and groundwater levels) mustbe monitored to reflect impacts of drought on agri-culture, households, industry, energy production,transportation, recreation and tourism, and otherwater users.
5. Determine the data needs of primary users. Devel-oping new or modifying existing data collection sys-tems is most effective when the people who will beusing the data are consulted early and often. Solicit-ing input on expected new products or obtaining feed-back on existing products is critical to ensuring thatproducts meet the needs of primary users and, there-fore, will be used in decision making. Training on how
DK2949_book.fm Page 107 Friday, February 11, 2005 11:25 AM
108 Wilhite et al.
to use or apply products in routine decision makingis also essential.
6. Develop or modify current data and informationdelivery systems. People need to be warned ofdrought as soon as it is detected, but often they arenot. Information needs to reach people in time forthem to use it in making decisions. In establishinginformation channels, the monitoring committeeneeds to consider when people need what kinds ofinformation. These decision points can determinewhether the information provided is used or ignored.
B. Risk Assessment Committee
Risk is the product of exposure to the drought hazard (i.e.,probability of occurrence) and societal vulnerability, repre-sented by a combination of economic, environmental, and socialfactors. Therefore, to reduce vulnerability to drought, one mustidentify the most significant impacts and assess their under-lying causes. Drought impacts cut across many sectors andacross normal divisions of government authority. These impactshave been classified by Wilhite and Vanyarkho (2000) and areavailable on the website of the National Drought MitigationCenter (NDMC) (
http://drought.unl.edu
).The membership of the risk assessment committee
should represent economic sectors, social groups, and ecosys-tems most at risk from drought. The committee’s chairpersonshould be a member of the drought task force. Experience hasdemonstrated that the most effective approach to follow indetermining vulnerability to and impacts of drought is tocreate a series of working groups under the aegis of the riskassessment committee. The responsibility of the committeeand working groups is to assess sectors, population groups,communities, and ecosystems most at risk and identify appro-priate and reasonable mitigation measures to address theserisks. Working groups would be composed of technical special-ists representing those areas referred to above. The chair ofeach working group, as a member of the risk assessmentcommittee, would report directly to the committee. Following
DK2949_book.fm Page 108 Friday, February 11, 2005 11:25 AM
Drought Preparedness Planning: Building Institutional Capacity 109
this model, the responsibility of the risk assessment commit-tee is to direct the activities of each of the working groupsand make recommendations to the drought task force on mit-igation actions.
The number of working groups will vary considerablybetween countries or provinces, reflecting the principal impactsectors. The more complex the economy and society, the largerthe number of working groups is necessary to reflect thesesectors. Working groups may focus on some combination ofthe following sectors: agriculture, recreation and tourism,industry, commerce, drinking water supplies, energy, environ-ment, wildfire protection, and health.
In drought management, making the transition from cri-sis to risk management is difficult because little has beendone to understand and address the risks associated withdrought. A methodology has been developed by the NDMC tohelp guide drought planners through the risk assessmentprocess. This methodology focuses on identifying and rankingthe priority of relevant drought impacts; examining theunderlying environmental, economic, and social causes ofthese impacts; and then choosing actions that will addressthese underlying causes. What makes this methodology dif-ferent and more helpful than previous methodologies is thatit addresses the causes behind drought impacts. Previously,responses to drought have been reactions to impacts. Under-standing why specific impacts occur provides the opportunityto lessen impacts in the future by addressing these vulnera-bilities through the identification and adoption of specificmitigation actions. This methodology is described below,divided into six specific tasks. Once the risk assessment com-mittee identifies the working groups, each of these groupswould follow this methodology.
1. Task 1: Assemble the Team
It is essential to bring together the right people and supplythem with adequate data to make fair, efficient, and informeddecisions pertaining to drought risk. Members of this groupshould be technically trained in the specific topical areas
DK2949_book.fm Page 109 Friday, February 11, 2005 11:25 AM
110 Wilhite et al.
covered by the working groups. When dealing with the issuesof appropriateness, urgency, equity, and cultural awarenessin drought risk analysis, include public input and consider-ation. Public participation could be warranted at every step,but time and money may limit involvement to key stages inthe risk analysis and planning process (public review vs. pub-lic participation). The amount of public involvement is at thediscretion of the drought task force and other members of theplanning team. The advantage of publicly discussing ques-tions and options is that the procedures used in making anydecision will be better understood, and it will also demon-strate a commitment to participatory management. At a min-imum, decisions and reasoning should be openly documentedto build public trust and understanding.
The choice of specific actions to deal with the underlyingcauses of the drought impacts will depend on the economicresources available and related social values. Typical concernsare associated with cost and technical feasibility, effective-ness, equity, and cultural perspectives. This process has thepotential to lead to the identification of effective and appro-priate drought risk reduction activities that will reduce long-term drought impacts, rather than ad hoc responses oruntested mitigation actions that may not effectively reducethe impact of future droughts.
2. Task 2: Drought Impact Assessment
Impact assessment examines the consequences of a givenevent or change. For example, drought is typically associatedwith a number of outcomes. Drought impact assessmentsbegin by identifying direct consequences of the drought, suchas reduced crop yields, livestock losses, and reservoir deple-tion. These direct outcomes can then be traced to secondaryconsequences (often social effects), such as the forced sale ofhousehold assets or land, dislocation, or physical and emo-tional stress. This initial assessment identifies droughtimpacts but does not identify the underlying reasons for theseimpacts.
DK2949_book.fm Page 110 Friday, February 11, 2005 11:25 AM
Drought Preparedness Planning: Building Institutional Capacity 111
Drought impacts can be classified as economic, environ-mental, or social, although many impacts may span more thanone sector. Table1 provides a detailed checklist of impacts thatcould affect a region or location. Recent drought impacts,especially if they are associated with severe to extremedrought, should be weighted more heavily than the impactsof historical drought, in most cases. Recent events more accu-rately reflect current vulnerabilities, the purpose of this exer-cise. Attention should also be given to specific impacts thatare expected to emerge in the future.
To perform an assessment using the checklist in Table1, check the box in front of each category that has beenaffected by drought in your study area. Classify the types ofimpacts according to the severity of drought, noting that inthe future, droughts of lesser magnitude may produce moreserious impacts if vulnerability is increasing. Hopefully, inter-ventions taken now will reduce these vulnerabilities in thefuture. Define the “drought of record” for each region.Droughts differ from one another according to intensity, dura-tion, and spatial extent. Thus, there may be several droughtsof record, depending on the criteria emphasized (i.e., mostsevere drought of a season or year vs. most severe multi-yeardrought). These analyses would yield a range of impactsrelated to the severity of drought. In addition, highlightingpast, current, and potential impacts may reveal trends thatwill also be useful for planning purposes. These impacts high-light sectors, populations, or activities that are vulnerable todrought and, when evaluated with the probability of droughtoccurrence, identify varying levels of drought risk.
3. Task 3: Ranking Impacts
After each working group has completed the checklist in Table1, the unchecked impacts should be omitted. This new listwill contain the relevant drought impacts for your location oractivity. From this list, prioritize impacts according to whatwork group members consider to be the most important. Tobe effective and equitable, the ranking should consider con-cerns such as cost, areal extent, trends over time, public

For example, if your drought planning was going to be based on the “drought of record,” you would need to complete a historical review to identify the drought of record for your area and assess the impacts of that drought. You would then record the impacts on this checklist by marking the appropriate boxes under the “historical” column. Next, with the knowledge you have about your local area, if another drought of record were to occur tomorrow, consider what the local impacts may be and record them on the checklist under the “current” column. Finally, consider possible impacts of the same drought for your area in 5 or 10 years and record these in the “potential” column.
If enough time, money, and personnel are available, it may be beneficial to conduct impact studies based on common droughts, extreme droughts, and the drought of record for your region. These analyses would yield a range of impacts related to the severity of the drought, which is necessary for conducting Step 3 of the guide and could be useful for planning purposes.

opinion, fairness, and the ability of the affected area torecover. Be aware that social and environmental impacts areoften difficult, if not impossible, to quantify. Each work groupshould complete a preliminary ranking of impacts. Thedrought task force and other work groups can participate ina plenary discussion of these rankings following the initialranking iterations. We recommend constructing a matrix (seean example in Table 2) to help prioritize impacts. From thislist of prioritized impacts, each working group should decidewhich impacts should be addressed and which can bedeferred.
4. Task 4: Vulnerability Assessment
Vulnerability assessment provides a framework for identi-fying the social, economic, and environmental causes ofdrought impacts. It bridges the gap between impact assess-ment and policy formulation by directing policy attention tounderlying causes of vulnerability rather than the result,the negative impacts, which follow triggering events such asdrought (Ribot et al., 1996). For example, the direct impactof precipitation deficiencies may be a reduction of crop yields.The underlying cause of this vulnerability, however, may bethat the farmers did not use drought-resistant seeds,because they did not believe in their usefulness, the costswere too high, or there was some commitment to culturalbeliefs. Another example could be farm foreclosure. Theunderlying causes of this vulnerability might include small

farm size because of historical land appropriation policies,lack of credit for diversification options, farming on marginallands, limited knowledge of possible farming options, a lackof local industry for off-farm supplemental income, or gov-ernment policies. Therefore, for each of the identifiedimpacts from Table 1, begin asking why these impacts haveoccurred or might occur. It is important to realize that acombination of factors might produce a given impact. Itmight be beneficial to display these causal relationships insome form of a tree diagram (see examples in Figures 4 and5). Figure 4 demonstrates a typical agricultural example andFigure 5 a potential urban scenario. Depending on the levelof analysis, this process can quickly become somewhat com-plicated, which is why working groups must be composed of

the appropriate mix of people. Table 3 lists many factorsthat typically make an area vulnerable to drought; theseshould be considered when forming tree diagrams.
The tree diagrams illustrate the complexity of understand-ing drought impacts. The two examples provided are not meantto be comprehensive or represent an actual location. Basically,their main purpose is to demonstrate that impacts must beexamined from several perspectives to expose their true under-lying causes. For this assessment, the lowest causes on the treediagrams, the items in boldface, will be referred to as basalcauses. These basal causes are the items that have the potentialto be acted on to reduce the associated impact. Of course, someof these impact causes should not or cannot be acted on for awide variety of reasons (discussed in Step 5).
5. Task 5: Action Identification
Mitigation is defined as actions taken in advance of or in theearly stages of drought that reduce the impacts of the event.

Drought Preparedness Planning: Building Institutional Capacity 121
Once the group has set drought impact priorities and exposedthe corresponding underlying causes of vulnerability, it canidentify actions appropriate for reducing drought risk. Thematrix lists the impact as well as the described basal causesof the impact. From this point, the working group shouldinvestigate what actions could be taken to address each ofthese basal causes. The following sequence of questions maybe helpful in identifying potential actions:
• Can the basal cause be mitigated (can it be modifiedbefore a drought)? If yes, then how?
• Can the basal cause be responded to (can it be modifiedduring or after a drought)? If so, then how?
• Is there some basal cause, or aspect of the basal cause,that cannot be modified and must be accepted as adrought-related risk for this activity or area?
A list of potential actions to mitigate drought is availableat http://drought.unl.edu/plan/handbook/risk.pdf. As willbe discussed in the next section (Task 6), not all ideas areappropriate in all cases. Many of the ideas are more in therealm of short-term emergency response, or crisis manage-ment, rather than long-term mitigation, or risk management.Emergency response is an important component of droughtplanning, but it should be only one part of a more compre-hensive mitigation strategy.
6. Task 6: Developing the “To Do” List
After the group identifies the impacts, causes, and relevantpotential actions, the next step is to determine the sequenceof actions to take as part of the risk reduction planning exer-cise. This selection should be based on such concerns as fea-sibility, effectiveness, cost, and equity. Additionally, it will beimportant to review the impact tree diagrams when consid-ering which groups of actions need to be considered together.For example, if you wanted to reduce crop losses by promotingthe use of a different type of seed, it probably would not beeffective to educate farmers on the benefits of the new variety
DK2949_book.fm Page 121 Friday, February 11, 2005 11:25 AM
122 Wilhite et al.
if it is too expensive or there are government incentives forplanting other crops.
In choosing the appropriate actions, you may want to asksome of the following questions:
• What are the cost/benefit ratios for the actions identi-fied?
• Which actions do the general public consider feasibleand appropriate?
• Which actions are sensitive to the local environment(i.e., sustainable practices)?
• Do the actions address the right combination of causesto adequately reduce the relevant impact?
• Do the actions address short- and long-term solutions?• Which actions would fairly represent the needs of
affected individuals and groups?
This process has the potential to lead to the identification ofeffective and appropriate drought risk reduction activitiesthat may reduce future drought impacts.
7. Completion of Risk Analysis
Following Task 6, the risk analysis is finished. Remember,this is a planning process, so it will be necessary to periodi-cally reevaluate drought risk and the various mitigationactions identified. Step 10 in the planning process is associ-ated with evaluating, testing, and revising the drought plan.After a severe drought episode would be an appropriate timeto revisit mitigation actions in association with an analysisof lessons learned.
C. Mitigation and Response Committee
Mitigation and response actions may be the responsibility ofthe drought task force or be assigned to a separate committee.It is recommended that the task force, working in cooperationwith the monitoring and risk assessment committees, has theknowledge and experience to understand drought mitigationtechniques, risk analysis (economic, environmental, and socialaspects), and drought-related decision-making processes at
DK2949_book.fm Page 122 Friday, February 11, 2005 11:25 AM
Drought Preparedness Planning: Building Institutional Capacity 123
all levels of government. The task force, as originally defined,is composed of senior policy makers from various governmentagencies and, possibly, key stakeholder groups. Therefore, itis in an excellent position to recommend or implement miti-gation actions, request assistance through various federalprograms, or make policy recommendations to a legislativebody or political leader.
Mitigation and response actions should be determinedfor each of the principal impact sectors identified by the riskassessment committee. Wilhite (1997) assessed drought mit-igation technologies implemented by U.S. states in responseto drought conditions during the late 1980s and early 1990s.The transferability of these technologies to specific settingsor locations needs to be evaluated further. These droughttechnologies are available on the NDMC’s website(http://drought.unl.edu/mitigate/mitigate.htm).
The State of Georgia recently developed a drought man-agement plan and identified a broad range of pre-droughtmitigation strategies that could be used to lessen the state’svulnerability to future drought events. These strategies aredivided by sector into municipal and industrial, agriculture,and water quality. Selected examples of these actions areprovided in Table 4. These examples illustrate the types ofactions identified by states that have recently completed thedrought mitigation planning process.
Tribal governments in the United States, many of whichare located in extremely drought-prone areas, are also pursu-ing development of drought mitigation plans. For example, theHopi Nation followed the 10-step guidelines and the NDMC’srisk assessment methodology (Knutson et al., 1998) in its plandevelopment process. The plan is pending approval throughthe U.S. Bureau of Reclamation, which provided funding forits development. The vulnerability analysis revealed four sec-tors of concern: range and livestock, agriculture, village watersupplies, and environmental health. A unique feature of theHopi drought plan is the inclusion of current and proposedmonitoring systems to evaluate climatic conditions, soil, veg-etation, and water resources for farming, ranching, and domes-tic purposes. The drought plan describes establishing a

network of approximately 60 transects to provide a detailedanalysis of range conditions. The transects will be selected torepresent major climates, soils, water resources, and land usespresent on the Hopi reservation and will help identify trendsin vegetation health. These monitoring networks will not onlyhelp monitor and quantify the drought impacts, but also beused to assess the effectiveness of any mitigation actions thatare implemented.
As was the case with the Georgia plan cited above, theHopi drought plan developed a list of short- and long-termdrought mitigation and response actions for each impact area.For example, to mitigate range and livestock losses, the plansuggests that range management plans be completed for eachrange unit. To facilitate rotations and proper use of range-lands, the Hopi range management plan also includes fencingand water development projects for the unit range manage-ment plans. Water availability in these units will be improvedthrough a combination of rehabilitating surface waterimpoundments, additional wells at key locations, improvedwater distribution from the supply point to multiple stockwatering troughs, and other conjunctive uses. The Hopi plan-ners hope these mitigation actions will decrease the vulner-ability of the range and livestock economic sector.
In addition to identifying mitigation actions that willreduce the tribe’s drought risk, the Hopi drought plan isunique in that it identifies the responsible agencies, providesa timeline to complete the actions, and proposes a cost esti-mate for these actions. For example, a cost of $12 million isestimated to upgrade the water supply systems of 12 tribalvillages by improving pumping capacity, storage tank size,and pipe capacity. The tribe plans to seek funding for theseactions through a variety of agencies and sources whileenhancing water conservation at the same time.
Before the onset of drought, the task force should inven-tory all forms of assistance available from governmental andnongovernmental authorities during severe drought. The taskforce should evaluate these programs for their ability toaddress short-term emergency situations and long-term miti-

Drought Preparedness Planning: Building Institutional Capacity 129
gation programs for their ability to reduce risk to drought.Assistance should be defined in a very broad way to include allforms of technical, mitigation, and relief programs available.
D. Writing the Plan
With input from each of the committees and working groups,the drought task force, with the assistance of professionalwriting specialists, will draft the drought plan. After comple-tion of a working draft, we recommend holding public meet-ings or hearings at several locations to explain the purpose,scope, and operational characteristics of the plan. You mustalso discuss the specific mitigation actions and response mea-sures recommended in the plan. A public information special-ist for the drought task force can facilitate planning for thehearings and prepare news stories to announce the meetingsand provide an overview of the plan.
As mentioned previously, the plan should not be consid-ered a static document. The plan is dynamic. A copy of theplan should be available through the drought task force web-site and in hard copy form for distribution.
VIII. STEP 6: IDENTIFY RESEARCH NEEDS AND FILL INSTITUTIONAL GAPS
As research needs and gaps in institutional responsibilitybecome apparent during drought planning, the drought taskforce should compile a list of those deficiencies and make rec-ommendations to the appropriate person or government bodyon how to remedy them. You must perform Step 6 concurrentlywith Steps 4 and 5. For example, the monitoring committeemay recommend establishing an automated weather stationnetwork or initiating research on the development of a climateor water supply index to help monitor water supplies and trig-ger specific actions by state government.
DK2949_book.fm Page 129 Friday, February 11, 2005 11:25 AM
130 Wilhite et al.
IX. STEP 7: INTEGRATE SCIENCE AND POLICY
An essential aspect of the planning process is integrating thescience and policy of drought management. The policy maker’sunderstanding of the scientific issues and technical con-straints involved in addressing problems associated withdrought is often limited. Likewise, scientists generally havea poor understanding of existing policy constraints forresponding to the impacts of drought. In many cases, commu-nication and understanding between the science and policycommunities must be enhanced if the planning process is tobe successful.
Good communication is required between the two groupsin order to distinguish what is feasible from what is notachievable for a broad range of science and policy issues.Integration of science and policy during the planning processwill also be useful in setting research priorities and synthe-sizing current understanding. The drought task force shouldconsider various alternatives to bring these groups togetherand maintain a strong working relationship.
X. STEP 8: PUBLICIZE THE DROUGHT PLAN—BUILD PUBLIC AWARENESS AND CONSENSUS
If you have communicated well with the public throughoutthe process of establishing a drought plan, there may alreadybe better-than-normal awareness of drought and droughtplanning by the time you actually write the plan. Themes toemphasize in writing news stories during and after thedrought planning process could include:
• How the drought plan is expected to relieve droughtimpacts in both the short and long term. Stories canfocus on the human dimensions of drought, such ashow it affects a farm family; on its environmentalconsequences, such as reduced wildlife habitat; and onits economic effects, such as the costs to a particularindustry or to the state or region’s overall economy.
DK2949_book.fm Page 130 Friday, February 11, 2005 11:25 AM
Drought Preparedness Planning: Building Institutional Capacity 131
• What changes people might be asked to make inresponse to different degrees of drought, such asrestricted lawn watering and car washing or not irri-gating certain crops at certain times.
In subsequent years, you may want to do “drought planrefresher” news releases at the beginning of the most drought-sensitive season, letting people know whether there is pres-sure on water supplies or reason to believe shortfalls willoccur later in the season, and reminding them of the plan’sexistence, history, and any associated success stories. It maybe useful to refresh people’s memories about circumstancesthat would lead to water use restrictions.
During drought, the task force should work with publicinformation professionals to keep the public well informed ofthe status of water supplies, whether conditions are approach-ing “trigger points” that will lead to requests for voluntary ormandatory use restrictions, and how victims of drought canaccess assistance. Post all pertinent information on thedrought task force’s website so that the public can get infor-mation directly from the task force without having to rely onmass media.
XI. STEP 9: DEVELOP EDUCATION PROGRAMS
A broad-based education program to raise awareness of short-and long-term water supply issues will help ensure that peopleknow how to respond to drought when it occurs and thatdrought planning does not lose ground during non-droughtyears. Try to tailor information to the needs of specific groups(e.g., elementary and secondary education, small business,industry, homeowners, utilities). The drought task force or par-ticipating agencies should consider developing presentationsand educational materials for events such as a water awarenessweek, community observations of Earth Day, relevant tradeshows, specialized workshops, and other gatherings that focuson natural resource stewardship or management.
DK2949_book.fm Page 131 Friday, February 11, 2005 11:25 AM
132 Wilhite et al.
XII. STEP 10: EVALUATE AND REVISE DROUGHT PLAN
The final step in the planning process is to create a detailedset of procedures to ensure adequate plan evaluation. Periodictesting, evaluation, and updating of the drought plan areessential to keep the plan responsive to local, state, provincial,or national needs. To maximize the effectiveness of the sys-tem, you must include two modes of evaluation: ongoing andpost-drought.
A. Ongoing Evaluation
An ongoing or operational evaluation keeps track of how soci-etal changes such as new technology, new research, new laws,and changes in political leadership may affect drought riskand the operational aspects of the drought plan. Drought riskmay be evaluated quite frequently whereas the overalldrought plan may be evaluated less often. We recommend anevaluation under simulated drought conditions (i.e., droughtexercise) before the drought plan is implemented and period-ically thereafter. Remember that drought planning is a pro-cess, not a discrete event.
B. Post-Drought Evaluation
A post-drought evaluation or audit documents and analyzesthe assessment and response actions of government, nongov-ernmental organizations, and others and provides a mecha-nism to implement recommendations for improving thesystem. Without post-drought evaluations, it is difficult tolearn from past successes and mistakes, as institutional mem-ory fades.
Post-drought evaluations should include an analysis ofthe climatic and environmental aspects of the drought; itseconomic and social consequences; the extent to which pre-drought planning was useful in mitigating impacts, in facili-tating relief or assistance to stricken areas, and in post-recov-ery; and any other weaknesses or problems caused by or not
DK2949_book.fm Page 132 Friday, February 11, 2005 11:25 AM
Drought Preparedness Planning: Building Institutional Capacity 133
covered by the plan. Attention must also be directed to situ-ations in which drought-coping mechanisms worked andwhere societies exhibited resilience; evaluations should notfocus only on those situations in which coping mechanismsfailed. Evaluations of previous responses to severe droughtare also a good planning aid.
To ensure an unbiased appraisal, governments may wishto place the responsibility for evaluating drought and societalresponse to it in the hands of nongovernmental organizationssuch as universities or specialized research institutes.
XIII. SUMMARY AND CONCLUSION
For the most part, previous responses to drought in all partsof the world have been reactive, representing the crisis man-agement approach. This approach has been ineffective (i.e.,assistance poorly targeted to specific impacts or populationgroups), poorly coordinated, and untimely; more important,it has done little to reduce the risks associated with drought.In fact, the economic, social, and environmental impacts ofdrought have increased significantly in recent decades. A sim-ilar trend exists for all natural hazards.
This chapter presents a planning process that has beenused at all levels of government to guide the development ofa drought mitigation plan. The goal of this planning processis to significantly change the way we prepare for and respondto drought by placing greater emphasis on risk managementand the adoption of appropriate mitigation actions. The 10steps included in this process are generic so that governmentscan choose the steps and components that are most applicableto their situation. The risk assessment methodology isdesigned to guide governments through the process of evalu-ating and prioritizing impacts and identifying mitigationactions and tools that can be used to reduce these impacts forfuture drought episodes. Drought planning must be viewedas an ongoing process, continuously evaluating our changingvulnerabilities and how governments and stakeholders canwork in partnership to lessen risk.
