Climatic conditions, events and variability are important drivers of migration and displacement  , with migration responses to specific climate hazards being strongly influenced by economic, social, political and demographic processes  . Migration is among a wider set of possible adaptation alternatives and often emerges when other forms of adaptation are insufficient . Involuntary displacement occurs when adaptation alternatives are exhausted or not viable and reflects non-climatic factors that constrain adaptive capacity and create high levels of exposure and vulnerability  . There is strong evidence that climatic disruptions to agricultural and other rural livelihoods can generate migration  .
