Desertification of Arid Lands (Advances in Desert and Arid Land Technology and Development,) by H.E. Dregne | Jan 1, Hardcover. Currently, the most endangered regions are near the world's five main deserts, including the Sonoran Desert which lies in Northwest Mexico and the Southwest United States; the Atacama Desert in South America; the Kalahari Desert in Southern Africa; most of Australia; and the large desert mass made up by the Sahara, Arabian, Great Indian, Taklimakan, Gobi and the deserts Author: Maria Trimarchi.

It is a global issue of huge importance, though its effects are felt especially strongly in Africa.
Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly more arid.
It is the spread of arid areas caused by a variety of factors, such as through climate change (particularly the current global warming) and through the overexploitation of soil.

This book (with a foreword by eminent desertification specialist, Dr. Alan Grainger of Leeds University) provides a synthesis of what desertification means in the present day context of worldwide concerns about land degradation in the face of global (including climate) change, burgeoning populations, urbanization, and loss of biodiversity.
Desertification offers a comprehensive overview of the subject and clearly emphasizes the link between local and global desertification processes and how past and current policy has affected arid environments and their populations.

Desertification is the degradation of land, especially in deserts and dry areas. Desertification occurs because of unproper land use, and drastic climate changes.Desert and Desertification Introduction.
Deserts are very dry regions that have seasonal high temperatures, low sporadic rainfall, and a high evaporation rate. Areas that receive less than 10 in ( cm) of rain a year are generally classified as deserts.Over one third of the world’s land surface (38 percent) is threatened with desertification, according to a new study published in the International Journal of Life Cycle study.
