Increasing attention has been given to how climate change relates to migration over the past decades. Given the wicked nature of climate change and the ways it impacts existing migration motivations and patterns, the relationsip between both is not straightforward. In this keynote, I will delve deeper into this relationship, by setting out who is impacted by environmental change, and how environmental changes impact mobility patterns. Afterwards, I discuss how this gives rise to challenges related to climate justice, at the global, regional and local level. In doing so, attention will be paid to participatory policy making, intersectionality, inclusion of local views, spiritual/religious beliefs and health outcomes.
