This report reviews the key conceptual questions and issues discussed at the ‘Environmental Change and Global Migration Futures’ workshop that was organised by the International Migration Institute (IMI) at the University of Oxford as part of its Global Migration Futures (GMF) project, and held from 21–22 June 2012. The workshop involved early/mid-career and senior migration, environment, and climate experts from different regions across the world. Its aim was to begin elaborating a shared conceptual starting point and common language, to explore appropriate methods and methodologies, and ultimately to develop an improved understanding of the reciprocal relationship between environmental change and migration that is strengthened by the rigour of both the environment/climate and migration fields.
