The consequences of climate change on migration present humanity with an unprecedented challenge. The numbers of storms, droughts and floods have increased threefold over the last 30 years with devastating affects on vulnerable communities, particularly in the developing world. In 2008, 20 million persons have been displaced by extreme weather events, compared to 4.6 million internally displaced by conflict and violence over the same period. How many people will be affected by climate change by 2050? Forecasts vary from 25 million to 1 billion people with a figure of 200 million being the most widely cited estimate. The main purpose of this new book is to suggest concrete ways in which the international community can begin to address the huge gaps in our knowledge relating to the likely impact of climate change on migration. The book does this by taking stock of the existing evidence on the effects of climate change and environmental degradation on migration, providing a comprehensive overview of the findings of recent research studies. Throughout, our focus is centred on how research can best inform policy and provide the evidence which decision-makers will need in the future to plan for and respond to environmentally induced migration.
