The first concern in semi-arid populated areas; it is the availability of water in relation to a growing societal demand.The immediate objective of a strategy for conserving and improving the productivity of water resources is to halt degradation with all its known forms and to promote a sustainable economy that will preserve and even enrich the quality of the assets And predispositions identified at the regional level. Tebessa is considered a semi-arid environment characterized by the rarity and the random nature of the resources, linked to an unpredictable climate and highly variable from one year to the next; The "sheep region", the "pastoralism", the "nomadism", the vegetable production very seriously compromised both by- The scarcity of the water resource, the fragility of the soil, the poverty of the mode of production, Pastoral type, based on the constant mobility of the herd in search of palatable plant cover, inducing a seemingly irreversible effect of desertification The progressive generalization of a mode of "mining" exploitation, made possible by the increasingly widespread use Modern means of transport, food, communication of information ...In this study, we examine the main water resources of Wadi Mellegue basin, available renewable water resources; The prospects for changing demand and the risks of scarcity.
