The study reveals that individuals from agricultural regions in Mexico are increasingly crossing into the United States illegally in the wake of extreme weather events, such as droughts, and also face diminished prospects for returning to their home communities as weather conditions remain severe.
Researchers note that rising temperatures and prolonged droughts drain reservoirs and diminish agricultural output, particularly corn crops, creating significant economic distress for rural populations in Mexico, thus prompting increased migration.
According to projections, as global temperatures rise, rural communities dependent on agriculture in Mexico may face severe economic impacts, which researchers believe could significantly magnify migration rates between Mexico and the United States.
The connection between environmental stressors caused by climate change and migration is becoming increasingly evident, with scientists forecasting that rising sea levels and extreme weather could uproot millions worldwide in the coming three decades.
