  • 80% of agricultural production comes from rainfed, only 20% from irrigated, with significant regional variation.


  • 1. Nile Basin Development Challenge: Rainwater Management Systems Tilahun Amede and NBDC team Nile Basin Leader Kees Swaans and Ranjitha Puskur
  • 2. Phase 2
  • 3. SSA’s dependence on rainwater agriculture
  • 4. What is ‘RWMs’ in NBDC?
    • An integrated strategy: mapping, capturing, storing and efficiently using water at plot, farm, landscape and basin scales for both productive and domestic purposes;
    • Enhancing adaptation of communities to climate variability (e.g. floods and drought) by combining water, land and vegetation management across scales;
    • Facilitating collective action for managing natural resources at landscape scales (water, grazing, hills..);
    • Exploiting interface between diverse social and biophysical processes (i.e. water, soil, livestock, crops, pests, sedimentation) at landscape / basin, leading to resilience
  • 5. Five interlinked projects operating across scales
    • Nile 1: On learning from the past;
    • Nile 2: On integrated rainwater management strategies – technologies, institutions and policies;
    • Nile 3: On targeting and scaling out;
    • Nile 4: On assessing and anticipating consequences of innovation;
    • Nile 5: Nile Coordination and Change
  • 6. Linkages Sub-regional Landscape Farm level Impact Learning Communication Nile 5. Coordination / change Nile 4. Consequences, impact, tradeoffs Nile 2. Innovations, technologies , practices Nile 3. Mapping, targeting. Up-scaling Nile 1. Inventory and synthesis Linkages Linkages
  • 7.  
  • 8.
    • Interdisciplinary and inter-institutional team; work on cross cutting issues including resilience, systems, gender, social preferences;
    • Participatory M&E framework (OLMs) are used to monitor and evaluate progress and make adjustments;
    • Generic indicators against which the activities and expected results will be measured;
    • Development of common reporting formats allowing teams to better share lessons;
    • Capacity building (inc gender, M&E) built both into the whole Nile BDC implementation, individual activities based on needs assessment.
    Strongly interlinked NBDC projects
  • 9. Nile BDC Rainwater Management Systems
  • 10. Value-Addition by NBDC
    • Farm level
      • Participatory, integrated research approaches
      • Strategic entry points (‘turn keys’) on farm
      • Linkages among system components
    • Landscape level
      • Integrated research approaches (including water, land, vegetation, crop, livestock and other common property resources as components)
      • Strategic entry points (‘turn keys’) in landscapes, communities (increasing water storage for fruit production creates community enthusiasm and investments in landscapes around springs, etc.)
      • Collective action & negotiated land and water use practices ( drainage, niche compatibility in agroforestry, spring management, livestock grazing)
      • By-laws and institutional change in support of local resolutions
    • National / basin Scales
      • Analyzing and synthesizing scenarios & methods for out-scaling;
      • Facilitating knowledge sharing within Ethiopia, the basins and across;
      • Developing insights into basin level concerns e.g., Climate change food security, poverty alleviation & biodiversity conservation
      • RWMS and their widespread dissemination through informing policy; publications and guides to decision-makers, implementers and the scientific community at large
  • 11. Market incentives for Landscape Management
  • 12. Objectives of the workshop
    • Assessing science progress of the NBDC projects and the programme;
    • Reflect on Nile project complementarities and progress;
    • Consensus on core concepts and approaches
  • 13. Well come to NBDC!
