The document discusses rainwater management strategies for the Nile Basin Development Challenge. It presents a framework and analytical concepts for understanding rainwater management at different scales from landscape to basin. This includes defining goals, strategies, practices and interventions. Scenarios and recommendation domains are proposed to operationalize rainwater management strategies. The session will focus on identifying practices and discussing frameworks, concepts and scenarios. Understanding landscapes through site assessments and the basin through similarity analyses will also be covered.

6. Guiding principle RMS must be framed in a way that is useful for communication and analysis at a variety of scales and purposes:

7. landscape to basin

8. recommendation domains

9. impact assessment

10. scenarios

12. Landscape “A combined physical and social unit large enough to encompass the range of land uses on which local communities depend, either directly for provisioning ecosystem services (food, fiber, livestock, wood) or regulating services (watershed functions), and a range of social institutions which are directly responsible for resource management.” (N2 project proposal) “Landscapes are spatially defined units, whose character and functions are defined by the complex and region-specific interaction of natural processes withhuman activities that are driven by economic, social and environmental forces and values.” (Landscape Europe 2001) Meso-scale – consider at least one scale above and one scale below Nile BDC encompasses community to basin to nation

13. Landscape Rainwater Management Landscape niches have various functions, services: Hydrologic Livelihood Different niches call for different management Interaction amongst niches are biophysical and social Changes in the function or services in one niche cause feedbacks affecting others

14. Scenarios What scenarios are you planning to use? How will you implement them? Models - Impact of strategy, adoption Quantitative (water -SWAT) or qualitative (livelihoods-participatory), static What will happen to x if x is implemented? Story lines - vision and analysis of complex futures Qualitative story line development How will x play out in various possible futures? Linked story lines and models Semi-quantitative, dynamic What feedbacks drive change after an intervention?
