Income in Kip Figures in pie chart: number of labour days per year per household Baseline: optimized allocation based on projection of present activities Pilot: assuming interventions accommodated by reservoir operations (e.g. recession agriculture)
Decision Support Linking Reservoir Operation with Livelihood Options
DECISION SUPPORT LINKING RESERVOIR OPERATION WITH LIVELIHOOD OPTIONS 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 water use focus on water management• Can reservoir operation rules accommodate livelihood options for affected communities?
Case of the Nam Gnouang storage reservoir KeosaenkhamNam Gnouang Dam Typical cross section
Decision support: linking reservoir operation with livelihood options1. 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 banks b) Fish resources enhanced with constructed wetlands Modeling and simulation to explore win-win situations

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?
