Mutations socio-spatiales et environnementales du bassin minier de Gafsa (Sud Ouest de Tunisie) : apport des outils géomatiques

Abstract : Since the end of the 19th century, the mining area of Gafsa (south-west Tunisia) has specialized in the single-activity extraction and enrichment of phosphate for reasons of economic profits. With these exports, this area has suffered an intense degradation of soil resources, vegetation cover and an advanced deterioration of agricultural areas. The management of the mining infrastructure has failed to meet environmental standards, causing social and spatial inequalities and increasing the level of environmental risks.The mining activity was at the origin of the birth and genesis of the mining towns in the Basin of Gafsa (BMG). The formation of spontaneous cities has caused the disarticulation of the urbanization. Urban extensions, including the expansion of anarchic cities, extending to laundries and to mines, thus created conflicts with the phosphatier domain. All these factors make costly and complicated attempts at development and rehabilitation that mining companies do not dare to commit.Taking into account the complexity of the many social, spatial and environmental aspects of the BMG, we used both the classical geographical approach and the geomatics approach that seemed appropriate for better decision-making. The interest of this latter approach makes it possible to identify, analyze, and model the state of the sites, the urban and environmental mutations in relation to the spatial-mining growth.
