To develop agriculture in mountainous areas, environmental analysis is a necessary step. However, the classical methods of agro-ecological diagnosis, which are numerous and diversified, do not allow to study large spaces in a reasonable period of time and often do not meet the expectations of the practitioner of the field. The aim of this project is to implement an approach consisting of conducting an environmental analysis with a preference for the choice of a spatial dimension ( level of perception ) in line with the needs of the farmer ( agricultural spatial unit ). This analysis will be based on the most relevant physical, biotic and socio-economic indicators using two distinct but complementary approaches: - Firstly, by the synthetic view of the landscape offered by satellite imagery by limiting the number of ground surveys, a space remote sensing approach will be adopted; - Then, by the performance allowed by the Geographical Information System (GIS) tool, the spatially referenced data will be combined; - Finally, on the basis of the results of the agro-ecological diagnosis using the geomatics tool (cartography, remote sensing and GIS), development guidelines will be outlined to develop mountain lands (soil, water) and preserve the agro-ecosystems weakened by three (03) Test sites selected on a north-south transect in the Tlemcen wilaya. |
