Abstract
The FAO satellite remote sensing system ARTEMIS has recently been installed. It will support agricultural production and desert locust monitoring in Africa. In relation to these tasks, this study discusses and compares a rainfall and an evapotranspiration mapping technique for the Sahel region. Evapotranspiration maps reveal detailed soil moisture related patterns, resulting from rainfall. The mapping results indicate a potential of this technique for locust habitat monitoring and crop early warning.
