Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land.
Soil Erosion and Degradation: Simple Definition, Causes, Consequences
What is soil erosion and soil degradation? Although soil erosion is a natural process, human activities over the past decades have greatly accelerated it. In fact, according to the UNESCO , land degradation is undermining the well-being of two-fifths of humanity, driving species extinct and intensifying climate change. Soil erosion is a gradual process of movement and transport of the upper layer of soil topsoil by different agents — particularly water, wind, and mass movement — causing its deterioration in the long term. In other words, soil erosion is the removal of the most fertile top layer of soil through water, wind and tillage. Soil erosion is a consequence of unsustainable land use and other disturbances, such as fire, mining, or intensive agricultural uses.
Soil Erosion and Land Degradation: The Global Risks
Land degradation is the reduction or loss of the biological or economic productivity and complexity of rain—fed cropland, irrigated cropland, or range, pasture, forest or woodlands resulting from natural processes, land uses or other human activities and habitation patterns such as land contamination, soil erosion and the destruction of the vegetation cover UNCCD, Thirty-three per cent of global land area is degraded FAO, About 47 per cent of degrading land globally is forest; cropland accounts for approximately 18 per cent of the global total degraded land Bai et al. About two billion people and 1. The alarming rates of degradation globally have been recognized and accorded international efforts to help halt and reverse land degradation and combat desertification ibid.
Soil erosion leads to losses in soil and crop productivity, pollution of land and water resources, and a loss of farm income. Strategies to manage.
