As noted by AR5 , research on issues related to both climate-change impacts on livestock production-demand for which is expected to double by 2050 in a world of 10 billion people-and policy choices with regard to adaptation, especially at the local scale, is still limited but progressing . The promise of diversification of livestock animals , crop diversification and transition to mixed crop-livestock systems needs to be further explored. A study of livestock farmers in Pakistan showed that risk- coping mechanisms, such as purchasing livestock insurance and increasing land areas for fodder, are far more rewarding policy options in comparison with selling livestock and migrating to another place. Relatedly, the association of migration with adaptation measures is context specific and involves a number of factors pertaining to the socioeconomic circumstances of vulnerable agricultural groups in countries like India and Bangladesh . In the 2010 United Nations Framework Convention on Climate Change's Cancun Adaptation Framework, migration was recognised as a form of adaptation that should be included in a country's long-term adaptation planning where appropriate .
