Case Studies in the Upper Niger River Basin: Sustainable Livelihoods that Balance Natural Resource Conservation and Agricultural Production in the OHVN Zone and the Yatenga Plateau Cooperators: INSAH, OHVN, CONAGESE, and PNGIM; FEWS NET, SANREM/CRSP, CILSS, AGRHYMET, ICASA, ICRISAT/IER, French and Dutch researchers) Approach: Laboratory (Imagery 1965, 1988, 2000) Field Workshops

5. Case Studies in the Upper Niger River Basin: Hypotheses/Objectives: NRM Practices improve production, sustainability, environmental conservation Absence of practices resulted in land degradation Trends in Land Cover Performance can be monitored, documented, and quantified across the Sahel Practices and Performance are causally associated with climate/weather, cultural practices, economic drivers, and national and donor policies

6. Case Studies in the Upper Niger River Basin: Results/Deliverables: Cooperative Graphic, Statistical, Image analyses of three periods Digital Landsat and Corona Mosaics Analysis of Land Cover Performance with 1-km NDVI for Temporal and Spatial Anomalies Initiate an ArcIMS system for data querying and delivery at AGRHYMET Capacity Building and Regional Resource Development

13. The profile from the laser is used to measure the distance of the canopy from the ground and determine to relative tree heights in the disparity map generated from the 3D model.
