As an example, the U.S. state of Illinois alone once held over 35,000 square miles (91,000 km 2) of prairie land and now just 3 square miles (7.8 km 2) of that original prairie land is left. The over farming of this land as well as periods of drought and its exposure to the elements (no longer bound together by the tall grasses) was responsible ...

Common attributes of soil degradation can be salting, waterlogging, compaction, pesticide contamination, a decline in soil structure quality, loss of fertility, changes in soil acidity, alkalinity, salinity, and erosion. Soil erosion is the wearing away of topsoil by water, wind, or farming activities. [54]
Illinois has received 3.41 inches of rain in the first half of July, 1.6 inches more than in the entire month of June, and leading to higher soil moisture across the state. Levels at 4 ...

Globally, the annual loss of 76 billion tons of soil costs the world about US$400 billion per year. In Canada, on-farm effects of land degradation were estimated to range from US$700 to US$915 million in 1984. The economic impact of land degradation is extremely severe in densely populated South Asia, and sub-Saharan Africa. [8]
Soil degradation means that soil quality has diminished, which causes ecosystem functions to decline. [1] One third of the globe's land has degraded soil; [1] especially the tropics and subtropics with around 500 million hectares. [1] Soil degradation occurs due to physical, chemical, and biological forces. [5] These forces can be natural and ...
