Locations in the Global South have limited public budgets allocated to coastal adaptation and may rely on international donor aid . Such aid is often inconsistent and short term, which limits long-term maintenance of the knowledge, equipment and infrastructure needed to sustain adaptation measures beyond initial funding periods , with resultant negative consequences in places as different as Kiribati  and Bangladesh . Donor-funded adaptation programs aimed at promoting behavioural change, for example through coastal planning or new decision-making systems, require enduring training and institutional capacity, which is difficult to upkeep after aid is depleted. Donor funding is often project based and there are few avenues available to fund the additional permanent and long-term staff needed to bolster climate change institutions. Without funding to support additional staff, existing institutions often lack the human capacity and resources needed for coastal adaptation .
