Presentation Transcript

  1. Crop and Livestock Water Productivity in BNB • Water productivity and runoff gains from water logged soils Other soils with in high rainfall areas Vertisols Topographic data (GIS) Non drainable (<2% Slope) Drainable (2-8% slope) Potential Interventions 2. Crop selection + Improved Crop Management 1. Drainage + WH + Improved Crop management Weather, Soil, Crop data Modeling: Crop Water Productivity Current VS option 1, 2 Potential Models: AquaCrop, Budget, CropWat, APSIM Crop WP Excess Water Met. Stations, RCM, research stations

  2. 2. Crop and livestock productivity through RWMS Livestock management practices Livestock WP Crop WP Feed +Water Modeling: Crop WP Current VS RWMS Potential Models: AquaCrop, Budget, CropWat, APSIM Feed from non agri. land Feed Water Other feed sources eg. concentrate Input data Field survey by students? Crop Map + Management practices (Students) Soil Laboratory data + Sediment quality (students) Weather RCM +weather stations Management: Current Vs Improved Senarios Review + Field survey

  3. Implications at Basin Scale • Results from 1 and 2 are at landscape/farming system scale • A similarity Analysis to identify areas in the basin represented by landscapes in 1 and 2 • Analysis at basin scale would be done under necessary assumptions • Simple spreadsheet may be used
