Large-scale refugee movements and protracted refugee situations persist around the world. Protecting and caring for refugees is life-saving for the individuals involved and an investment in the future, but importantly needs to be accompanied by dedicated efforts to address root causes. While not in themselves causes of refugee movements, climate, environmental degradation and natural disasters increasingly interact with the drivers of refugee movements. In the first instance, addressing root causes is the responsibility of countries at the origin of refugee movements. However, averting and resolving large refugee situations are also matters of serious concern to the international community as a whole, requiring early efforts to address their drivers and triggers, as well as improved cooperation among political, humanitarian, development and peace actors.
