As it nears the end of its 4.5 year lifespan, the Deltas, Vulnerability and Climate Change: Migration and Adaptation (DECCMA) project has released a summary of its key findings on climate change, migration and adaptation. Deltas are home to 500 million people worldwide and play a key role in the economies of countries. Climate change exacerbates environmental change due to sea level rise, salinisation, flooding and coastal erosion, and different levels of social vulnerability create different risk profiles (including for men and women). Migration has long been evident in deltas (primarily from rural areas to urban areas) but environmental change alters the context in which migration decisions are taken, particularly when environmental factors reduce the ability to earn a living. As mobile environments, adaptation has always occurred, but more is likely to be required in the future. The publication also outlines some of DECCMA policy impacts building achievements. Kulima's role in DECCMA has been to ensure integration of gender, champion research impact activities, and contribute to adaptation research.
