Controlling tsetse has several environmental impacts, separated into two distinct types: direct and indirect. Most of the former tsetse control programmes had direct impacts on natural resources. As a result of the vector control, people are likely to settle in newly cleared lands after these are freed of the tsetse fly. The indirect impacts on the environnent are the effects through the settlement of human populations on wild areas, the expansion of livestock populations, and land-use change. The environmental monitoring is partly based on the analysis of land use and land cover change. Indicators of land transformation for agriculture, land use changes and land cover evolution combine several statistical data combining land use mapping and socio-economic surveys, which are compared in a spatial location and within temporal interval of several years. The trends of environmental consequences can be deduced from these changes. This present consultacy is placed at methodological and training level, whose objectives are to help the ILRI GIS specialist working on the project and one or two members of national institutions to analyse high definition satellite imageries and produce land use mapping.
