Use cases: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,

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.

2. Hydrological model:
-WaSiM-ETH Model for Atankwidi subcatchment,
- 12 months modeling period (01.01.2004 to 31.12.2004),
- validation done by one year runoff data “Kandiga Junction”,
- simulation run with a spatial resolution of 100m and a daily temporal resolution,
- the simulation included fictive reservoir and a fictive irrigation field,
