L' aménagement des périmètres publics irrigués en zones arides

Fackeldey, Eric
In the arid and desert areas of southern Tunisia, the government has for several years been developing cases in the Sahara (Ibn Chabet at Tozer, Régim Maatoug at Kebeli, etc.) and irrigated areas in the "steppes". These oases and irrigated areas are based on the use of non-renewable fossil layers of water ("Continental Intercalaire" and "Complexe Terminal"). In the governorate of Tataouine, more than twenty irrigated areas have been created of which 16 are presently functional. However, the targets fixed for these areas have still not been rearched and some of them, above all those in the southern part of the governorate, face problems of non exploitation, poor management of resources and sometimes even abandonment. The present study is the contribution of an ICRA interdisciplinary research team towards the searh for solutions for the existing irrigated areas and the development of new orientations for the creation of future irrigated areas in the region. This study analyses the many constraints both socio-economic (lack of financial resources, great distance between the irrigated areas and the residential zones of the beneficiaries, etc.) and technical (lack of specific norms for the region, etc.). The permanent request for government intervention to resolve these problems, despite the important efforts already realised exposes the problem of the utility and purpose of these government interventions with regard to the adopted strategy of disengagement.
