SIG ET TÉLÉDÉTECTION POUR L'ÉTUDE DE L'ENSABLEMENT
DANS UNE ZONE ARIDE : LE CAS DE LA WILAYA DE NAÂMA (ALGÉRIE).

Abstract : n Algeria, nearly 20 million hectares are threatened by wind erosion. For a long time, the phenomenon of wind erosion and its harmful effects on the natural environment constitute a serious problem, especially in the arid regions of the country. These last years, following the irrational exploitation of the natural resources (fodder) and with the setting in culture of the fragile grounds (clearing) this process was particularly accentuated. The extent of degradation in the arid region of the wilaya of Naâma generated a new situation characterized by the reduction of vegetable cover, the decrease in the production as well as the extension of the fast stranding on the zones development.

With through this study, we tried to show on the one hand, the potential of the use of the remote sensing and the GIS for the characterization of the condition of the land use and its space-time evolution from the treatments carried out on a series of Landsat TM and MSS imagery of various dates (1972, 1987 and 2002).
In addition to place at the disposal of the potential users and the decision maker's information on the environment and the natural resources of these zones, via the installation of a prototype integrated in a geographical information system. The prototype is conceived based on the principle of double-prototyping method. The system will be a tool of decision-making aid, useful for the management of the natural phenomena, and more particularly the land degradation and the stranding of the grounds of the wilaya of Naâma.
