![]() The impacts of climate change are already being felt from the tropics (e.g., small island states, coral reefs) to the arctic (e.g., first nations communities). ![]() The need for adaptation to climate change is an emerging focus of international policy. Adaptation funding directed to these areas could simultaneously address multiple international policy goals, including poverty reduction, protecting agricultural production and safeguarding ecosystem services. Agreement among multiple climate models and emissions scenarios suggests that these priorities are robust. ![]() The priority areas are locations where changes in crop suitability affecting impoverished farmers intersect with changes in ranges of restricted-range species. An additional seven regional areas are identified as worthy of additional study. Here we show that human and natural adaptation needs related to maintaining agricultural productivity and ecosystem integrity intersect in ten major areas globally, providing a coherent set of international priorities for adaptation funding. Climate change adaptation funding may be most effective where it meets integrated goals, but global geographic priorities based on multiple development and ecological criteria are not well characterized. International policy is placing increasing emphasis on adaptation to climate change, including the allocation of new funds to assist adaptation efforts.
