WP6 is a central component of the project. The WP will be mainly driven by the involvement of stakeholders. This will include both a macro framework of action wherein the development of adaptation measures across the multiple sectors and scales through a participatory mode involving interactions at the institutional and community levels. The development of adaptation measures across the multiple sectors and scales will follow a two phase approach (after Manez et al., 2007). Phase I makes an inventory of the changes around water and water management and their impacts. Stakeholders in both upstream and downstream areas are identified as well as present perception of problems and strategies and measures. The knowledge required for different measures will be identified (input to WP3, 4 and 5). Possible measures include floods, droughts, water harvesting, small dams, irrigation, change of land-use, change of forest cover, ecological changes, changes in energy supply and consumption. In Phase II the participatory assessment of measures will take place, bringing the different stakeholders, from different sectors together, to discuss the combined effect of measures, the selection of modelling scenarios and the common prioritization of measures.
For each sector targeted i) water supply, ii) hydropower, iii) agriculture, iv) health, v) ecosystem experts will elaborate with local stakeholders for their perspectives on the multi-sector interventions to define adaptation measures. Using the information from the individual test sites at characteristic hydrological and socio-economical conditions the design of virtual measures will be elaborated. Using the indicator system elaborated in WP5, the impact of measures on water quantity, water quality, socio-economy and adaptive capacity will be formulated. Results from WP6 will be reconsidered in a feedback loop at WP1, WP2 and WP3. As part of WP6 four case studies are foreseen, combining both the regional and the sub-regional level and the possible differences in priorities for adaptation in the upstream and downstream area.
