Soil Degradation: Food Security
2014Growing populations lead to an increasing demand for food. With decreasing per-capita areas of arable land, this leads to additional pressure and stresses on the limited land resources, especially the soils. As a consequence, large parts of the world are affected by soil degradation, and this has a direct effect on food security.

Estimates in 1991 suggest that about 240 M ha land is chemically degraded. Nutrient depletion has affected 136 M ha, salinization damaged 77 M ha, and acidification degraded 6 M ha. Another 11 M ha is affected by soil pollution. Agricultural mismanagement (58 %) and deforestation (28 %) are the main causes of chemical degradation of soil.

Land Degradation & Development, 2001
AbstractSoil degradation by accelerated erosion is a serious problem and will remain so during the 21st century, especially in developing countries of the tropics and subtropics. Yet, its extent, severity, and economic and environmental impacts are debatable. Estimates of global and regional land area affected are tentative and subjective.
