Public ISBD Titre : Sahel-Sudano Désertification study Type de document : texte imprimé Auteurs : Worcester, B. K. ; Dalsted, K. J. ; Moore, D. G. Mention d'édition : Departement of State Agency for International Developpement Editeur : Departement of State Agency for International Developpement Année de publication : 1978 ISBN/ISSN/EAN : CI-00313 Note générale : This stydy was initiated to evaluate the usefulness of landsat data for monitoring the effects of desertication on arid and semi-arid lands. A stydy area was selected which encompases parts of Mauritanie, Mali and Senegal. This is an area where evapotranspiration exceeds precipitation annually. It is therefore very susceptible to indicatirs of short, intermediate and long term desertication effects are illustrated and discussed. Short term effects are shown in a very fragile area where vegetation is evident during a higher precipitation year, 1976, but not during drier hears, 1972 and 1977. This amount of water in stream and river channels is illustred as a short term indicator. The extent of flooding in flood recession agriculture ares is also visualized...
