The study found that, between 1982 and 2015, 6% of the world's drylands underwent desertification driven by unsustainable land use practices compounded by anthropogenic climate change. Despite an average global greening, anthropogenic climate change has degraded 12.6% (5.43 million km 2 ) of drylands, contributing to desertification and ...
The risk of desertification threatens arid and semi-arid regions throughout the world. Population growth, urbanization, an increase in cultivated land areas, overgrazing, and deforestation adding to the effects of climate change exacerbate the issues. Alfa grass cover has decreased while the quality of the grasslands itself is becoming ...
