Water and wind erosion are now the two primary causes of land degradation; combined‚ they are responsible for 84% of degraded acreage‚ making excessive erosion one of the most significant global environmental problems. Industrial agriculture‚ deforestation‚ roads‚ anthropogenic climate change and urban sprawl are amongst the most significant human activities in regard to their effect on stimulating erosion. However‚ there are many available alternative land use practices that can curtail or limit
