A novel approach adopted by the trypanosomiasis control project GCP/TOG/013/BEL involves systematic, grid-based sampling to correlate all the geo-referenced data relevant to understanding the disease and its impact and to planning intervention. Data collected through field surveys are related to satellite imagery, provided by FAO ARTEMIS, as well as to other existing data sources on land-use pasterns end demography for prediction exercises and analysis using a geographical information system. The information obtained advocates practical control in the form of decentralized programmes involving livestock keepers and private veterinarians. This innovative approach may serve as a model for trypanosomiasis control in the onchocercosis-freed areas of West Africa as well as elsewhere in tsetse-infested sub-Saharan Africa.
