摘要

The increased exploration of the underground water and soil in the Northeast of the Algerian Sahara for the sake of drinking and irrigation has resulted in catastrophic hydro-geological and environmental problems, especially the rise of the level of the superficial layer that affects agriculture and environment. This is mainly a consequence of the mismanagement of the extracted water resources, that has in turn caused bio-climatic and geomorphologic problems, especially in the Oued Souf and Oued Righ region. This phenomenon has escalated, especially after the increase in the land cultivation projects, which were often practiced without prior hydro-cultural analyses, as well as a consideration for irrigation water drainage. This has in turn created other problems, such as a significant increase of the amount of salt in soil and which has resulted in the spoiled and desertification of large fertile plots of land. Besides, the aggressive livestock herding causes poor biological renovation of the wild plantation.rnIn addition, there are some social communities that consume high amounts of water, which exceed 500 L per day per capita, while the sewage system is underdeveloped and cannot cope with such high levels of drained water. As a result, water is drained in some traditional wells (septic pits). The poor management of water resources resulted in disastrous outcomes, which consisted mainly in the rise of the free level of the phreatic water and saltiness, which affect agriculture and infrastructure. Thus, this paper aims at shedding more lights on the desertification and degradation of the environment, as well as compiling additional scientific proofs for the research dealing primarily with the results of the human interference in the environment.rnIn order to lessen such catastrophic results, a reasonable management of underground water resources cannot be neglected, especially in regions supplied with such a strategic resource, for a sustainable development. Otherwise, the escalating mismanagement of our water resources, with no planning and policy, would lead to disastrous outcomes. A continued disrespect of this precious resource means an unwise consideration of the fate of the future generations. Therefore, directory plans for the arrangement and management of the soil and water resources, in terms of hydro-agricultural capacities, should be put in place. In addition, regular measuringrnof the piezometric levels of different underground napes exploited should be recorded. The technical outline of research in the hydro-agricultural and urban arrangement fields should be identified before hand. This would improve the management of soil and water resources, as well as stimulating search for irrigation systems suitable for the climate conditions of the region.
