ABSTRACT
Global climate change is the most serious environmental problem of the twenty-first century. The change in climate has already begun with a global increase in temperature during the twentieth century, and considering different scenarios, projected increase in temperature will continue until the end of the twenty-first century. The carbon (C) cycle plays a significant role in global climate change both in its causes and in its remediation. International conventions and the sustainable management of the land by agriculture can be important forces in using the carbon cycle for the remediation of global warming brought about by the greenhouse effect. Vegetation and soil can be either sources or sinks for atmospheric carbon. Entropic factors such as land use, land cover, and agricultural practices govern actual C stock in soils. Soil organic matter is also a key factor that plays a role in exacerbating desertification or in its prevention or remediation process.
