Land degradation takes a number of forms, including depletion of soil nutrients, salinization, agrochemical pollution, soil erosion, vegetative degradation as a result of overgrazing, and the cutting of forests for farmland. When land is degraded there can be serious effects such as erosion, loss of soil fertility, reduced crop yields, flooding and water shortages. These impacts include compaction, loss of soil structure, nutrient degradation, and soil salinity. The locations surveyed were the Rano and Danbatta Agricultural Development Programme (ADP) zones of Kano State and the Funtua and Ajiwa ADP zones of Katsina State. Causes of Soil Erosion agricultural practices. Deforestation and degradation can impact heavily on small communities who are dependent on forests as a source of emergency income and food during famine or economic hardship. One of its main causes is the over grazing of land.

Consequences of Land Degradation. The degradation of agricultural and pastoral land in Australia is a matter of considerable concern. The logging and clear-cutting of rain forests are some of the leading causes of soil erosion worldwide. The environmental consequences from the industrial production of meat include air and water pollution ,land degradation and deforestation. In the Amazon rain forest of Brazil for example, an area the size of a football field is cut every second, leaving vast swaths of land vulnerable to wind, rains and floods that cause erosion. Over time, this causes land degradation, which in turn may have negative effects on. Land Degradation Soil degradation is the decline in soil quality caused by its improper use, usually for agricultural, pastoral, industrial or urban purposes. 1 Patterns and causes of resource degradation. While drought increases soil degradation, soil degradation, in turn, magnifies the impact of drought.
