This document discusses using GIS for research and development in agriculture, specifically for cocoa production in West Africa. It summarizes that GIS can be used for spatial targeting, mapping disease distribution, and identifying suitable areas for intensifying cocoa production while avoiding deforestation. The document provides examples of using GIS to analyze cocoa suitability in Nigeria based on climate and soil factors, and to identify suitable local government areas for investment based on biophysical, socioeconomic and demographic criteria. It also discusses using GIS for disease monitoring and training agricultural researchers and technicians.
