AR5  concluded that migration is often, though not in all situations, a potential form of adaptation initiated by households. Subsequent research indicates that the circumstances under which migration occurs and the degree of agency under which household migration decisions are made are important determinants of whether migration outcomes are successful in terms of advancing the well- being of the household and providing benefits to sending and receiving communities  . Evidence from refugee studies and general migration research indicates that higher agency migration, in which migrants have mobility options, allows migrants greater opportunities for integrating into labour markets at the destination, makes it easier to remit money home and generally creates conditions for potential benefits for migrant households and for sending and receiving communities . Bilateral agreements that facilitate labour migration have been identified as being especially urgently needed for Pacific small island states .
