Some definitions

  • Rainwater management practice = farmers’ choice to improve water retention or water productivity

    • Soil and water conservation (bunds, …)

    • Water harvesting

    • Tree (agro-forestry)

    • Livestock and grassland management

    • Crops and fertility management

  • Intervention = “external actor” to enable a practice change

Overview

  • Introduction

  • Concepts used (definitions)

  • Modeling framework with illustration

  • Using the maps

  • Up-coming research


Mapping rainwater management strategies at landscape scale nile 3 on targeting and scaling out

Using the maps

  • High uncertainty

  • Difficulty to validate the maps

  • Entry point to start a discussion with community

  • Towards an open source GIS tool for policy makers, research centers, NGO, extension service

Up-coming research

  • Map validation in 4 new watersheds

    • Using the “happy strategy game”

    • Farm household survey (600 farmers)

  • Impact assessment

    • on hydrology, ecosystem services, livelihoods

  • Explorative scenarios
