The increase in greenhouse gas emissions, primarily carbon dioxide, methane, and nitrous oxide, leads to global warming and climate change, which in turn affects arid and semi-arid regions, causing migration.

Rising sea levels are primarily associated with climate change impacts in coastal regions, not arid and semi-arid regions.

Climate change affects the livelihoods of people living in arid and semi-arid regions by reducing agricultural productivity, increasing water scarcity, and leading to the loss of grazing land, among other impacts.

People migrate from arid and semi-arid regions due to climate change primarily to seek better living conditions, including access to food, water, and other resources.
