destinations, labour market choices and returns from migration may be more heavily constrained than those of other labour migrants .Within low- and middle-income countries, rural-urban migrant networks are important channels for remittances that may help build socioeconomic resilience to climate hazards in sending areas , with higher levels of wage-seeking labour participation observed in climate- sensitive locales in south Asia . Local-level research in China and south Asia shows, however, that the potential for remittances to generate improvements in household level adaptive capacity is highly context specific, has significant gender dimensions and depends on such factors as the nature of the hazard, the distance migrated and the length of time over which remittances are received . Social networks are a key asset in helping climate migrants overcome financial and structural impediments to their mobility, but these have their limits, particularly with respect to international migration . Since AR5, greater restrictions have emerged on movement between many low- and high-income countries , a trend that, if it continues, would generate additional constraints on destination choices for future climate migrants . Transnational diasporic connections are a potential asset for building resilience in migrant-sending communities highly exposed to climatic risks, with migrants' remittances potentially providing resources for long- term resilience building, recovery from extreme events and reducing income inequality . Safe and orderly labour migration is consequently a potentially beneficial component of wider cross-sectoral approaches to building adaptive capacity and supporting sustainable development in regions highly exposed to climate risks .
