Public ISBD Titre : Application of erts products in range and water management problems- Sahelian zone, Mali, Upper Volta, and Niger. Type de document : texte imprimé Auteurs : Cooley, E. M. ; Turner, M. R. Mention d'édition : US Geological Survey Editeur : US Geological Survey Année de publication : 1975 ISBN/ISSN/EAN : CI-00054 Note générale : This reprt describes the results of a brief field investigation by the writers during April and May 1974 to evaluate application of ERTS imagery to range and water management problems in Mali, Upper Volta and Niger. The report concludes that the imagery can provide general overviews of regions or no good ground surveys exist/ can provide a basis for repetitive inventorying and monitoring transient environnemental changes on the earth's surface/ and aid in solving special problems of disese vector or control or Human activity. Specific application of ERTS imagery were identified in river-blindness control/ tse-tse fly control/ bush-burning evaluation/ disuntion of arable from non arable lands/ analysis of problems of accelerated erosion/ the annual flood of the Niger river/ and ground-water developpement in fratured rocks.
