Les potentialités hydriques et la phoeniculture dans la vallée de l'Oued Righ : (Bas-Sahara algérien)

Abstract : Climatic conditions give to Oued Righ area a vocation of the Saharian agriculture dominated by palm-cultures. This vocation is explained by the existence of exceptional hydrological conditions. In fact, Oued Righ Valley is part of the Algerian Bas-Sahara which contains important subterraneous sheets of water, particularly the continental intercalation. However, if the use of these sheets has permitted the development and the expansion of cultures, their immoderate exploitation has considerably disturbed the balance of sheets (decline of the hydrostatic levels). Today, in order to safeguard oases and sheets, some requirements are indispensable. Important investments are necessary on thone hand, to achieve a modern and rational irrigation and a diversification of cultivations (by the regeneration of existing palm-groves, and the development of new areas) ; on the other hand, to a limitation of harnessing works and a strict control over the exploitation of water. All these actions lies within an over all development program concerning the whole region.
