Answer: Soil deterioration is a worldwide phenomenon. It includes both physical loss (erosion) and nutritional decline and contamination, as well as a reduction in topsoil quality.
The progressive conversion of habitable land to desert is known as desertification. Soil erosion has consequences that go beyond the loss of agricultural land. It has resulted in a rise in pollutants and sedimentation in streams and rivers, blocking them and causing fish and other species to decline.
Degraded areas are also less capable of retaining water, which can exacerbate flooding. Sustainable land use can help to mitigate the effects of agriculture and cattle, minimising soil degradation and erosion, as well as the desertification of valuable land. Farmers and the worldwide community are concerned about soil health because their livelihoods are dependent on well-managed agriculture, which begins with the dirt beneath our feet.
