dc.description.abstract | Water and soil are the most valuable capital for man. These fragile resources are
undergoing unprecedented qualitative and quantitative degradation. The problem of soil
degradation that no country seems to escape, dangerously affects agricultural production
and therefore food security.
In Algeria, the problem of water and soil degradation remains a major concern.
The main causes are erosion and desertification, which are mainly linked to human
activities and climate change. About 6 million hectares are exposed to active erosion
today and averages of 120 million tons of sediment are washed away each year by the
waters threatening the dams (Heddadj, 1997). Population sustenance is increasingly
threatened by accelerating of erosion (Sari, 1977) mainly in mountains with more than 8
million people. (Taabni, 1998)
In this research work, we will develop the subject of climate change and its impact
on soil productivity. | en_US |
