  1. 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

  2. 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?

  3. Case of the Nam Gnouang storage reservoir Typical cross section Keosaenkham Nam Gnouang Dam

  4. Decision support: linking reservoir operation with livelihood options • How would affected communities best use the land and water resources at their disposal to enhance their livelihoods? • Can reservoir operation rules accommodate their livelihood needs with minor impact on hydropower production? • Recession agriculture on seasonally-exposed reservoir and river banks • Fish resources enhanced with constructed wetlands •  Modeling and simulation to explore win-win situations

  5. A suite of modeling and simulation tools Land use planning & analysis system (LUPAS) - Explore cost-effective options of livelihood activities based on land and labour resources at their disposal Examine the interaction between reservoir operation & livelihood opportunities GIS modeling & analysis - Spatial analysis and mapping support Reservoir simulation (ResSim) - Simulate fluctuation of water level

  6. Slope suitability Physical access by boat & road Least A suite of modeling and simulation tools Least Least Most suitable EP LUPAS Most suitable Most suitable ResSim GIS Overall suitability for recession agriculture Exposure period Keosaenkham An opportunity to create constructed wetlands ?

  7. Slope steepness A suite of modeling and simulation tools Evaluate quality and access to land resources THPC designated land use zones for Keosaenkham LUPAS Accessibility taking account of road travel only Accessibility taking account of road and river travel Accessibility taking account of road travel only Easy access ResSim GIS Easy access KSK KSK Increased difficulty of access without boat travel Difficult access Difficult access KSK Designated zone for upland rice Division of labour for livelihood activities KSK

  8. Year 5 Year 1 Year 2 LUPAS simulation: income scenarios Baseline 10 M 22 M 13 M Pilot 14 M 18 M 26 M

  9. 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?
