Many small island, rural and indigenous peoples’ communities are on the frontlines of climate change. Arctic, high altitude, desert margin and small island communities suffer early impacts due to the particular vulnerability of their territories and their reliance upon resource-based livelihoods.These communities have first-hand knowledge of climate change impacts and strategies for response, due to their long-term observation and engagement with their environments.Despite broad recognition of their vulnerability, and unique knowledge and experiences, their voices have been largely unheard.Climate Frontlines aims to bring the knowledge and concerns of vulnerable communities into global climate change debates.
