The goal of the Nile BDC is to improve rural livelihoods and their resilience through a landscape approach to rainwater management

RMStrategiesTo operationalize the concept of Rainwater Management the Nile BDC:

• Rainwater management = management of all the water in a landscape, green and blue water, rainfall and rivers, soil water and ground water

• Guiding principle RMS must be framed in a way that is useful for communication and analysis at a variety of scales and purposes:– landscape to basin

– recommendation domains

– impact assessment

– scenarios

• Four elements: A goal and a strategy to reach that goal including the interventions needed to achieve change in practice at farm, landscape, or even higher levels.

RMS in the Nile BDCFor the Nile BDC we define the following

This session focus primarily on the practices

Goal: translation of the project goals/impact into measureable objective for the basin or landscape

Goal: Example from Jeldu: Increase and diversify tree cover, system intensification including increased storage of water, transition to new crop varieties

Strategy: plan to achieve the goal

Practice: a way of doing something that addresses single or multiple niches in the landscape, biophysical

Intervention: anything done to achieve a practice change, target actors who can make changes, social process

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 with human 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 belowNile BDC encompasses community to basin to nation

Landscape Rainwater Management

Landscape niches have various functions, services: HydrologicLivelihood

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

Scenarios• What scenarios are you planning to use?• How will you implement them?

Models - Impact of strategy, adoption

Story lines - vision and analysis of

complex futures

Quantitative (water -SWAT) or qualitative (livelihoods-participatory), static

What will happen to x if x is implemented?

Qualitative story line developmentHow will x play out in various possible futures?

Linked story lines and models

Semi-quantitative, dynamicWhat feedbacks drive change after an intervention?
