North –the poorest in Laos & 70% residents ethnic minorities.
– diverse cultures & identities intimately linked to natural environments in which peoples live-pristine environment
– Poor living condition- infants death & child health the worst in Asia. Only 30% access to safe drinking water
– Traditional farm-rotational: rice maize, vegetables & livestock. Food from nature over 50% of total – mostly from forest & some rivers products.
– Seasonal food insecurities (4-6 months)
– Less NTFP now- because rapid forest loss push from regional economic integration, logging, concessions, land clearing -farming

Benefits from MRB resourcesBenefits from MRB resources Benefits from MRB resourcesBenefits from MRB resources
Highland peoples- very small demand for water – Water for drinking & washing from mountain springs or streams.
– Watershed in head water area for 1) farming- natural moisture. 2) animals grazing land for livestock & 3) forests for collection NTFP
– Few benefits from fish in their immediate stream- or by trading
N highland –Thai –bigger demand for water- – 1) Water for irrigation – orange orchards & dry season rice – 2) water for light industries and other urban uses – 3) clean water for tourists (food & drink, resorts- golf courses
bathing & drinking) – 4) clean healthy – scenic rivers for cruising /rafting – water sports– 5) cheap apples /fruits & electronic goods from china –via cargo
ship from China via bigger navigation route on mainstream

LMB Planning issuesLMB Planning issues LMB Planning issuesLMB Planning issues Land use changes in the catchment –can affects flows into the Mekong –
more sediment. Affects sustainability of upland agriculture & livelihoods of the ethnic highland peoples.
Managing the catchments is complex. The Lao Government committed to stop shifting cultivation, but ethnic minorities have not many alternatives.
– Are there ways to practice shifting agriculture more sustainably, through better erosion control method?
– Ways to increase cash income for poor ethnic communities? By making use of cultural resources via co-cultural tourism? so environment – development- ethnic culture - can co exist?
– How to articulate water allocation in Thailand? Commercial production( big farm) – river /water quality for tourism? Safe sufficient –unpolluted water sources for local domestic uses ?

Mekong Fish suppliers to Laos & Thailand – Both banks - many tributaries- has flood exchange with
Mekong- create many associated wetlands & rich in fish – Fish has food & cultural importance

Esan – more options for earning– Get from agriculture /farming
rice & cash industrial crops, Sticky rice for food, Jasmine for sale
– $$ wage income – various options in employment Agro processing & service sector in NE work in urban & big cities - mass migration
– Only 40 % Esan people get main income from agriculture
People in Central Laos – Majorities are subsistent food producer –rice. Some
vegetables – Local natural resources important base- important for all
earnings – Fishing & hunting for food important for mass rural folks->

– Laos- network for 290,000 ha for wet & 197,000 ha for dry season. 92,000 ha of dry season rice harvested in 2000. Low % of use due to high operation costs & low return
– Thai-network for 750,000ha primarily for wet season. Less than 15% are used for dry season -- since not economical & labor not available, too expensive
Instream water use – maintain fisheries. Natural fish very important food- most Lao rural folks little cash
earning to buy food. Family fish ponds largely trap natural fish for later food. Fisheeires-Thai side both economic and culture importance
– Clean rivers for aquaculture – Mekong + tributaries
Head water for hydro power – export-government income Water for Industrial & urban uses Water for home use-drinking washing- surface & undergorund In land Water - transports – 10 of thousands people in Laos for wet season

Irrigation -potential to improve livelihoods. At present use on high yield crops & riskier than traditional farm. Irrigation costs -> diesel pumping is expensive. So are investment costs for farms inputs
– What support is needed to ensure that irrigated agriculture give net benefits to farmers? How to make good use of existing systems & small farmer profits ?
Protecting the capture fishery is a priority for Thai government. \
– How can urban planning be improved- the floodplain which are important for fisheries are not lost?
Development in Thailand needs energy, and Laos has hydropower potentials ( one source of energy)
– How to plan hydropower developments so that they provide the best hydropower outcome for the least environmental, social and economic cost ?
– Are their different water used options without uprooting vulnerable people, but get similar national income gain?

There is good potential for hydropower in the southern highlands. The Yali Dam was built on the SeSan River in 1995 to produce hydropower .
The operation of the dam has resulted in un-seasonal flooding which has severely affected the people living downstream from the dam
7 more dams is being planned in South Laos-In river XePian , Xe Namnoy,
Xe Kham Marn

Planning IssuesPlanning IssuesPlanning IssuesPlanning Issues The region – main source of eater to MK. Local demand still small- but soon could
change due to rapid development - VN side. Changes in land use may have an impact on the water flow- more sediment & change ecology of fish
How to manage forest & land resource sustainably ? protect the water resource shared by all, and the forest resources important for highland people ?
How can the Mekong valuable fish species be maintained so common assets to all still exist ?
* Laos has water potential for hydro dams & Cambodia needs cheaper energy for its population & Thailand /Vietnam can use more energy
Can hydro potentials be exploited with least environment & social cost to groups already in dire poverty? Least impact on fisheries downsttream which is life sources for for millions?
What are the economic & social “ trade off “ between national income & local food security via various water use options?
How can water based development be done in balancing “ national –regional income growth with social equity ? –keeping humans’ diversities ( cultures) ecology?

Tonle sap & Mekong delta most productive in both agriculture
and fisheries production
The southern floodplains and delta
Covers 28 provinces ( 15 Cambodia & 12 Vietnam)
Population 25 millions
21
Tonle sap region ( Pop5.1 mil) is the poorest part of Cambodia estimated at 1.8 mil people
Life depend on annual flooding to bring fish to floodplain, also fertile soil and water for rice ( floating, receding & dry season rice)
High % landlessness so people here get large part of benefits from common/public space- flooded forest, open water, channels
Fish has economic, employment and food security important to Cambodia
Livelihood rice- fish & few cash earning opportunities outside agriculture
The southern Floodplains & Delta

Delta – 20 mil people ( 14. 7 mil in VN- 5.5 in Cambodia) poverty rate is 33% -but not too far below poverty line
Livelihood on rice cultivation & fishing & fish (cage) culture & elementary occupations- small scale trade & job in agro/ or garment industries
Smaller land holding 1 ha (Cambodia 1h/ family & VN below ½ ha)

Planning issues Planning issues Planning issues Planning issues
Level fertilizer /pesticide use is growing. Fertilizer run-off often results in eutrophication as the water becomes too nutrient rich-can affect fish. Chemicals in fish can affect people who consume the fish
Non –rice crops often require protection from floods and so there is an increasing number of levee banks being built on the delta.
Increasing urban populations is also increasing the amount of flood protection works being undertaken.
Aquaculture in the delta - done with little attention to disposal of waste products. The VN supports sustainable aquaculture by promoting rice-prawn systems, but the Government has few resources for extension.
