HORTICULTURE

Detailed explanation-1: -The acts of compaction and erosion as a result of overgrazing can cause tremendous land degradation. In drier areas, the experience is even worse as a large percentage of pasture and land cover is destroyed, contributing to the relentless progression of desertification.

Detailed explanation-2: -CONSEQUENCES OF DESERTIFICATION Food insecurity due to crop failure or reduced yields. The loss of vegetation cover and therefore of food for livestock and humans. Increased risk of zoonotic diseases, such as COVID-19. Loss of forest cover, with a corresponding shortage of wood resources.

Detailed explanation-3: -Overgrazing reduces the usefulness, productivity and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds.
