Influence of overgrazing on the runoff and soil loss on hillslope [articol]

Abstract

Overgrazing is an actual problem especially in countries where the economy is largely based on animal husbandry. Overgrazing occurs when land are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods of vegetation. Overgrazing favors soil erosion, resulting in reduction of soil depth, soil organic matter content and soil fertility. These impair the land’s future natural and agricultural productivity. This paper studies the influence of overgrazing on the runoff and soil loss on hillslope. The modelling is performed using WEPP software.
