In Central America, drought has caused increased unemployment and decreased food security - also causing migration of people. Similar impacts have been seen in rural parts of Mexico where about 1,000 km 2 of land have been lost yearly due to desertification. [74] In Argentina, desertification has the potential to disrupt the nation's food ...

Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
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 2018–2021 Southern Africa drought was a period of drought that took place in Southern Africa. The drought began in late October 2018, and negatively affected food security in the region. In mid-August 2019, the drought was classified as a level 2 Red-Class event by the Global Disaster Alert and Coordination System . [ 1 ]
