  2. 2. Projects, Partners and UsersProjects: NBDC (CPWF), Afromaison (EU)Partners:International- ILRI, ICRAF, IFPRI, ODI, NBI,Cemagraf, Cornell University.National- Ethiopian Universities, Regionalresearch authorities, Ministry of Agriculture,Ministry of Water and Energy, Nat. Met.Agency, River Basin Authorities, NGO’s Water for a food-secure world www.iwmi.org
  3. 3. Problem• In Ethiopia 95% of agriculture is rainfed. Subject to high variability in rainfall and access to water. In these areas rural communities are vulnerable to food insecurity and a high incidence of poverty.• What are the opportunities and constraints (biophysical, social, economic) to changing this at a landscape scale? (Knowledge, Attitudes and Skills) Water for a food-secure world www.iwmi.org

  8. 8. Climate Forecast and Reanalysis System Use as input to models as secondary data at regional scale to provide a consistent methodology 1979 – 2010 (will be updated to present > near real-time) Coupled atmosphere-ocean-land-sea ice system Finer spatial (~38km) and temporal (hourly and daily) resolution 700 600 y = 0.568x + 21.37 R² = 0.876 500 400 300 STN 200 100 0 CFSR -100 100 300 500 700 Water for a food-secure world www.iwmi.org

Issues Site Main Issue Related Issues Unrestricted Land Fogera grazing degradation Land Termite Diga degradation infestation * Jeldu Soil erosion Deforestation Fodder interventions have been selected by stakeholders in all three sites to address these issues* Interventions in Diga linked to CPWF Termite Action ResearchProject Water for a food-secure world www.iwmi.org
  14. 14. Demand Driven Action Research-Innovation Fund • 5000 USD allocated to platforms to fund activities which address RWM issues • Proposals and action plans developed by stakeholders according to defined criteria • Actions are cross-sectoral, participatory, designed to address RWM issues and targeted to suitable area • Sites have been selected in areas within the designated NBDC watersheds • Action at household level, farmland and communal land Water for a food-secure world www.iwmi.org

Learning so farResearch outputs Inform policyInformation on: •Suggestions for alternatives to current• Livelihood strategies and constraints practices• Factors influencing adoption/lack of adoption • Piloted processes that can be tested and• Social, economic and political drivers of replicated for use in planning andlandscape change implementation• Development of research/implementation •Concrete outcomes that can be fed toprocesses national level platform• Experiences, lessons, best practice Water for a food-secure world www.iwmi.org
