Drought, flight, conflict: 'climate migration' as a driver for conflict?

So-called "climate migration", i. e. human mobility following prolonged drought periods, floods, or other climate-related environmental changes, has been singled out as an important factor connecting climate change effects and (violent) conflict. However, the existing studies on this relationship do not offer a clear picture. Nevertheless, Syria has evolved into a "show case study" for this assumed linear causality: A "century drought" and ensuing internal migration are seen as an untold prequel of the Syrian uprising. This alarmist, determinist, and simplifying image is questioned and reviewed in order to answer the following questions: Was the Syrian drought related to or caused by climate change? Which role, if any, did it play for internal migration in pre-revolutionary Syria? What do we know about "drought migrants" and their role in the Syrian uprising? The article summarizes available research and adds to it by way of interviews with Syrian refugees.
