Migration

Climate change and migration: an overview (Global Encyclopaedia of Migration, 2013)

There is considerable historical and contemporary evidence that changes in climatic conditions have the potential to influence human migration patterns. Anthropogenic climate change will oblige human populations to undertake a range of adaptive strategies, which will happen at a variety of scales and levels from the individual or house­ hold through to higher­ level institutions. The range of adaptation options available to a given population will vary according to the broader social, economic, and political context that determines household well­being. Read more…


The numbers game (Forced Migration Review, 2008)

Estimates of the potential number of ‘climate change migrants’ vary hugely. In order to persuade policymakers of the need to act and to provide a sound basis for appropriate responses, there is an urgent need for better analysis, better data and better predictions. Read more…


Migration and Climate Change (IOM, 2008)

Predicting future flows of climate migrants is complex; stymied by a lack of baseline data, distorted by population growth and reliant on the evolution of climate change as well as the quantity of future emissions. Nonetheless this paper sets out three broad scenarios, based on differing emissions forecasts, for what we might expect. These range from the best case scenario where serious emissions reduction takes place and a “Marshall Plan” for adaptation is put in place, to the “business as usual” scenario where the large-scale migration foreseen by the most gloomy analysis comes true, or is exceeded.
