2. Integrating Governance & Modeling Challenge Program White Volta Basin Sub-Project

3. Governance & Modeling Challenge Program Use cases: In consultation with Ministry of Food and Agriculture and the Water Resources Commission, Modeling Workshop in Jan. 2006, 1.Evaluating third cropping season strategy, 2.Evaluating the impact of Credit Market Reforms,

4. Governance & Modeling Challenge Program Modeling: 1.MAS: Optimization component: -New household survey not enough for input- output estimation, -Started with old Matrix, -Representing the third cropping season (maize) a challenge: -New proposal and no household level data, -MoFA did experiments but no recorded data, -Alternative CropWat, FAO report and data from case farmers visited during different survey times.
