Aménagements anti-érosif des terres agricoles des piémonts Nord-Ouest du Dahra (W. Mostaganem)

Abstract

The problem of water erosion is global; Algeria is affected by this phenomenon, which remains dangerous as it accelerates the degradation of soil subjected to the combined energy of raindrops. We chose the farmland of Douar Naimia, southern Sidi Ali (Mostaganem), where water erosion is becoming important. It is a serious threat for agricultural soils, which can influences, badly, the productivity. The objective of this study is to identify sensitive areas and high erosion risk in order to achieve a priority area of intervention for card tried to proposed anti-erosion management plan for the three zones with a priority for each, for take on developed the developed of risk on this farmland. For each zone a combination of management measures both preventive (biological) and curative (mechanical) have been proposed but their sustainability is conditioned by the participation of the local population.
