AR5 noted that whether migration is adaptive or maladaptive depends on the context and the individuals involved; however, it did not focus specifically on hydrological change-induced migration . Migration is often regarded as a transformational adaptation strategy in response to climate-induced hydrological changes  but rarely as the primary or only adaptation measure . Migration is among one of the top five adaptation responses documented in Asia and Africa  and confers several benefits to migrants, yet maladaptations are also documented . This strategy is not available to everyone. Vulnerable populations exposed to hydrological changes may become trapped due to a lack of economic and social capital required for migration  .
