Climate change is disrupting traditional livelihoods, forcing millions of people worldwide to consider alternative options. These disruptions do not affect women and men, boys and girls equally. The options available to people are also not equal. While circular migration — within countries and regions — has long been a practice of livelihood security, climate change impacts are forcing new kinds of human mobility, for which people and states are not prepared. Although these mobilities may be complex and multi-dimensional, it is important to understand different “push factors” and “pull factors” through the lens of climate change impacts, because such impacts are well evidenced to have significant bearings on livelihood security across developing countries.
