DIAGNOSIS ON THE CURRENT SITUATION OF CERTAIN WETLANDS OF THE OUED RIGH REGION (ALGERIAN SOUTHEAST)

Abstract

Water plans are many in Algeria and shelter very precious and diversified biological resources. These environments are of fresh, brackish, salty or hyper-salty water. The first ones are widely used for the irrigation. Other environment can be valorized by a rational and long-lasting exploitation for their fauna or for the salt which they produce. Wetlands situated in arid and semi arid zones (chotts, sebkhas, lakes, geltas and oasis) are important water reservoirs for the local communities and which receive several species: either aquatic (fishes, crustaceous, seaweeds …), or no-migratory and migratory birds. They have to benefit, in the future, from a particular attention on behalf of the State and of the international community. The wetlands of the region of Oued Righ (Algerian southeast) constitute particularly sensitive environments. They play a very important ecological role within the hydro-system and an economic role for the local actors. In the valley of Oued Righ, the physical chemical quality of surface water of these last year’s knew a big deterioration. The discharges of the urban areas and the industrial park are directly often forwarded at the courses of waters and they are the causes of the ecological disturbances of the wetlands of the region subscribed on the list RAMSAR.
