REMOTE SENSING AS AN AID FOR AREA ESTIMATION OF RAINFED CROPS IN SAHELIAN COUNTRIES
This paper presents a methodology under evaluation for the multi-level space stratification meant for the estimation of rainfed foodcrops. The experiments are carried out in the Republic of Mali in the frame of the JRC's "Joliba Project", in cooperation with the CILSS and local partners. Three different spatial levels are taken into account: 1) the agricultural regions, 2) the land-facets, and 3) the fields. For each level, the application of remote sensing is assessed, and if necessary, alternative solutions are proposed, especially for the third level. Finally, a series of actions initiated in 1986 are presented in order to assess some specific points of the methodology. Among them: acquisition of Landsat MSS and SPOT imagery, 1/10 000 IRFC air photos, large scale air photo and radiometry with ultralight, and field survey.
