Gully in arid climate.

Gully erosion destroys agricultural and domestic grazing land in many countries, especially those with arid and semi-arid climates and easily eroded rocks and soils. It also generates large amounts of sediment that can adversely impact downstream river channels.Over 80 years, gully density has significantly increased to 1.59 km km −2 with less vegetation growing in their channel, but 66% of these gullies were treated with check dams. There was c. 3 km km −2 of indigenous SWC structures ( daget or lynchets) in 1935–1936 whereas a high density (20 km km −2 ) of introduced SWC structures (mainly ...Hyper-arid zones have an index of less than 0.03 and cover 4.2% of land on the planet, arid zones have an index range of 0.03 -0.20 and cover 14.6% while semi-arid zones have an index range of 0.20-0.50 and cover 12.2%.
