Descripción
This workshop originated from a study sponsored by FAO and executed jointly by the Comité interafricain d'études hydrauliques (CIEH), the Laboratoire commun de télédétection Cemagref-Engref (LCT) and Orstom (Institut français de recherche en coopération). The study investigated the potential use of remote sensing and geographic information systems in water resources assessment of small watersheds in semi-arid areas of West Africa.This workshop was organized with the objective of reviewing the state of the art in the use of remote sensing for water resources assessment and management with special reference to operational techniques. Emphasis was placed on surface hydrology, with applications for arid and semi-arid areas in developing countries for which such techniques are believed to be of particular relevance.The workshop gathered experts from ten countries, as well as researchers and students from Montpellier and Toulouse. In total, there were one hundred participants. The conclusions presented in the summary are intended to clarify the state of the art in application of remote sensing for water resources, to identify current constraints and potential of existing techniques and to suggest avenues for further research and more efficient technology transfer.
