New study An international team from Africa, Asia and Europe put forward three criteria for assessing the success of migration as an adaptation to climate change: well-being, equity and sustainability. The study shows that while migration is increasingly recognized as an effective way to address climate risks or a form of adaptation, it is far from the best solution. For example, remittances – which include flows of money, ideas, skills and goods between migrants and their places of origin – are considered key to facilitating adaptation to climate change.
