He stated that there were 25 million environmental refugees in the mid-1990s, further claiming that this figure could double by 2010, with an upper limit of 200 million by 2050. [19] Myers argued that the causes of environmental displacement would include desertification, lack of water, salination of irrigated lands and the depletion of ...
Climate migration is a subset of climate-related mobility that refers to movement driven by the impact of sudden or gradual climate-exacerbated disasters, such as "abnormally heavy rainfalls, prolonged droughts, desertification, environmental degradation, or sea-level rise and cyclones". [1]
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 ...
Desertification in Africa is caused by both natural and man-made forces. Climate change, which has resulted in increased aridity and decreasing rainfall in many regions, and soil erosion, which happens naturally but can be exacerbated by human activity, are the principal natural elements that lead to desertification.

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 ...
Climate migration is the displacement of people both internally within countries or internationally due to climate-related disasters, which include both rapid and slow onset events. Slow onset events describe natural disasters that are exacerbated by anthropogenic climate change and occur over several years or decades. [ 1 ]
The United Nations Convention to Combat Desertification in Those Countries Experiencing Serious Drought and/or Desertification, Particularly in Africa (UNCCD) is a Convention to combat desertification and mitigate the effects of drought through national action programs that incorporate long-term strategies supported by international cooperation and partnership arrangements.
The environment and all its inhabitants rely on biodiversity to recover from extreme environmental conditions. When too much biodiversity is lost, a catastrophic event such as an earthquake, flood, or volcanic eruption could cause an ecosystem to crash, and humans would obviously suffer from that. [ 55 ]
