Climate change has had a devastating impact on many poor Central American farmers, which can contribute to food insecurity and may be prompting migration from the region's Dry Corridor. But the process is not straightforward. As this article explains, most poor farmers rely on a combination of buying, cultivating, and foraging for their food, which makes it difficult to predict how people will react to individual climate events.
In recent decades Russia has been increasingly reliant on Central Asian migrant workers. Those workers, in turn, have sent back remittances that have been crucial for their countries of origin.
