A Review on: Management of Carbon in Dry Land Agriculture

Dry land areas are defined as regions in which the ratio of total annual precipitation to potential evapotranspiration (P:ET or the Aridity Index, AI) ranges from 0.05 to 0.65. Dry lands have a strong impact on the global C cycle, in which Land-use changes, land degradation and desertification holds the major share on emission of CO2 into the atmosphere. Carbon sequestration is the long-term storage of carbon in oceans, soils, vegetation...
