Recent literature has also put forward the concept of migration as a climate change coping mechanism. Climate change push factors are weighed against economic or social pull factors: the role of climate change in migration is thus not a linear one of cause and effect. Migration frequently requires would-be migrants to have access to social and financial capital, such as support networks in the chosen destination, and the funds to be able to move. It is frequently the last adaptive response households will take when confronted with environmental factors that threaten their livelihoods, and mostly resorted to when other mechanisms to cope have proven unsuccessful. 'Migration and Climate Change', a UNESCO publication, explores the dynamics of environmental migration and the role of migration as an adaptive response to climate change (Unescopress 2011).
