Most salt-degraded cropland occurs in Asia and southwesternNorth America, which account for 75 and 15 percent of the worldwide total, respectively. In Asia, Iraq has lost over 70 percent of its irrigated land to salt accumulation. In Russia, much of the irrigated land located where theVolga...
Thedesertificationof America’s farmland is not the first. — Astra Lincoln,Outside Online, 15 Dec. 2022 There, a dearth of job opportunities and an increase indesertificationhad led to crop failures and migration away from the semi-arid land. ...
Today, desertification is devouring more than 20,000 square miles of land worldwide every year. In North America, 74% of the land in North America is affected by desertification while in the Mediterranean, water shortages and poor harvests during the droughts of the early 1990s exposed the acut...
Desertification is a land degradation problem of major importance in the arid regions of the world. Deterioration in soil and plant cover have adversely affected nearly 50 percent of the land areas as the result of human mismanagement of cultivated and range lands. North America and Spain have th...

Paleosols in the northern Chihuahuan Desert of North America indicate that there have been multiple geomorphic responses to bioclimatic changes over the late Quaternary. The nature and magnitude of these responses is being sought by investigating pedogenic horizons and redoximorphic features using thin ...
Since regional variations in climate are the main causes of the loss of dryland productivity, it is important to understand the influence of global warming in specific dryland regions. According to some models of climate change, many grasslands in western North America, for example, are predicted ...
And the regions of Africa, North America, and northern areas of China and India have an increased risk of desertification. The researchers called for a global action plan to reduce the risk of desertification and mitigate the effect of high-risk desertification expansion....
Counties with extreme or strong karst rocky desertification risk (43.48%, nearly half of the study area) were clustered in the north, central and southeast portions of the study area. Counties with low karst rocky desertification (30.43%) were located in the west, northeast and southwest of ...
