Therefore, the traditional view of adaptation as a local process has now widened to recognise it as a multi-actor process that transcends scales from the local and sub-national to national and even international  . Many of the impacts of climate change are both local and transboundary, so that local, bilateral and multilateral cooperation is needed . National policies and transnational governance should be seen as complementary, especially where they favour transnational engagement with sub- and non-state actors . National governments typically act as a pivot for adaptation coordination, planning, determining policy priorities, and distributing financial, institutional and sometimes knowledge resources. National governments are also accountable to the international community through international agreements. National governments have helped enhance adaptive capacity through building awareness of climate impacts, encouraging economic growth, providing incentives, establishing legislative frameworks conducive to adaptation and communicating climate change information .
