Detailed explanation-1: -It is usually caused due to the removal of vegetation, or any activity that renders the ground dry. Farming, grazing, mining, construction and recreational activities are some of the causes of soil erosion.
Detailed explanation-2: -For areas with light erosion problems, replanting with vegetation and covering with mulch are good solutions. For erosion along footpaths, covering with mulch or stone is the best option. For heavy erosion in areas of concentrated flow, the most effective solutions are check dams or terraces.
Detailed explanation-3: -The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
