Case example from Lao PDR
Kam Suan Pheng, Chu Thai Hoanh, Julia Reis, Guillaume Lacombe, Teoh Shwu Jiau
Mekong Forum on Water, Food and Energy
Session 1 Starting Small: Hydropower dams for water, food and energy
13 November 2012
Decision support: for what purpose?• To maximize power supply; optimize multiple To maximize power supply; optimize multiple
water use water use focus on water management focus on water management
• Can reservoir operation rules accommodate Can reservoir operation rules accommodate livelihood options for affected communities?livelihood options for affected communities?
Case of the Nam Gnouang storage reservoir
Nam Gnouang Dam
Keosaenkham
Typical cross section
1. How would affected communities best use the land and water resources at their disposal to enhance their livelihoods?
2. Can reservoir operation rules accommodate their livelihood needs with minor impact on hydropower production?a) Recession agriculture on seasonally-exposed reservoir and
river banksb) Fish resources enhanced with constructed wetlands
Modeling and simulation to explore win-win situations
Decision support: linking reservoir operation with livelihood options
Reservoir simulation (ResSim)- Simulate fluctuation of water level
Land use planning & analysis system (LUPAS)- Explore cost-effective options of livelihood activities based on land and labour resources at their disposal
GIS modeling & analysis- Spatial analysis and mapping support
A suite of modeling and simulation tools
Examine the interaction between reservoir operation & livelihood opportunities

Points for discussion
• What DSS have been developed that may provide useful information to a hydropower company on how to change their operating rules to enhance local livelihood opportunities?
• What would be the enabling environment required for hydropower companies/operators to take account of the findings of these decision support systems?
