اهمیت مدیریت و الگوی استفاده از اراضی در مهار فرسایش خاک (مطالعه موردی: آبخیز سد کمال صالح)

Climate Change and land use can affect the amount of erosion and the ability of the soil to maintain agriculture and, as a result, food security. On the other hand, the increase in population requires more food resources, which has caused more pressure on water and soil resources. One of the consequences of this pressure is the intensification of the soil erosion process, which, while reducing the soil fertility,. Therefore, the correct pattern of land use in watersheds should be observed in order to increase the profit from the available resources and reduce the damage caused by soil erosion. One of the solutions is to apply management programs and optimize land use accordingly. For this purpose, in this research, the amount of soil erosion was estimated in the Adina watershed in the Markazi province in three current conditions, the condition of management practices and the standard condition of the land. The results showed that the annual erosion rate for three management conditions is 9.31, 7.67 and 6.65 tons per hectare per year, respectively, and in the conditions of applying land management, the erosion rate is 17.61 compared to the current conditions, and in the standard conditions, it is 17.57 has decreased by 28%. Therefore, the implementation of management programs and paying attention to land capability has an important role in reducing the rate of erosion, but the prerequisite for its implementation is paying attention to the needs and income of the watershed residents.
