Linking climate change, environmental degradation, and migration: An update after 10 years

Abstract

In WIREs Climate Change, Issue 1(4), 2010, I suggested a typology of the data and methods used to assess links between climate change, environmental degradation and migration (Piguet, 2010). My review of the literature included publications up to 2009. Since then, the number of empirically based scientific publications on this topic has risen substantially to average 40 articles per year and the scope of methods, stock of results and diversity of questions has widened. Based on the CLIMIG database—a systematic and analytic collection of scientific references published on migration and the environment—this new synthesis provides a methodological typology of an exceptionally large number of published case studies. This will complement existing reviews and meta‐studies and allow a global overview of the state of research by identifying consensus and disagreements, revisiting methodological challenges and mapping current and future research questions.
