ABSTRACT
Climate change has become widely accepted as an intensifying challenge to contemporary society (Smith et al. 2010). In many areas in the world, more erratic weather, rising sea levels and other climate change-related phenomena are expected to pose significant challenges in terms of their effect on development and livelihoods, settlement options, food production and disease. Human migration has been identified as the greatest single impact of climate change (IPCC 1990, IPCC 2007a), with the population involved in climate change-induced migration estimated at between 50 million and 1 billion people by 2050 (United Nations 2009).
