This document discusses the relationship between environmental change and human migration. It provides context on definitions of "environmental refugees" and "environmental migrants." While some studies estimate millions of people could be displaced by 2050 due to climate change impacts, there is low confidence in precise projections. The document examines factors like drought, flooding, and sea level rise that may influence migration patterns. However, it also notes that most environment-related movement is temporary and within countries or regions. The document considers policy options around addressing protection gaps for people displaced by environmental impacts. It frames addressing migration as an adaptation strategy and discusses approaches like building resilience and flexibility into governance.
