This Staff Working Document provides an overview and assessment of existing EU policies, instruments and practices addressing displacement and migration of populations caused by disasters4 , the adverse effects of climate change and environmental degradation. This document underlines the increased exposure to disasters and the consequences of the current state of management of natural resources and weakened ecosystems. Furthermore, it highlights the actions taken by the EU in third countries to prevent and prepare for such displacement, to assist persons displaced or at risk of displacement, to strengthen their resilience and protection as well as to enhance the systems which provide support and services to them. It covers both internal and crossborder movements, including displacement related to disasters (such as those caused by floods, earthquakes and tropical cyclones) and mobility linked to the adverse effects of climate change and environmental degradation (such as desertification, coastal erosion, pollution, prolonged or frequent droughts). This document does not address the impact of disasters, climate change and environmental degradation on population movements within the EU. This document builds on existing EU policies and documents that address the issue of disaster and climate-related displacement, including the Green Deal5 and the Pact on Migration and Asylum . It aligns to internal policy and stems from the urgency for the European Union (EU) to give a comprehensive external response to this global challenge, which is growing in scale and impact, and affects more people around the world every year. This Staff Working Document is the result of extensive consultations with a number of international organisations, non-governmental organisations and United Nations (UN) entities engaged in addressing disaster and climate-related displacement globally.
