Pacific Island Countries and Territories are highly exposed to natural disasters, intensified by increases in frequency and force of extreme weather events. Pacific societies, like in Vanuatu, have been shaped in many ways by such natural disasters; reflected in customary practices and social fabric of rural coastal communities. When a natural disaster occurs, government attention justifiably focuses on channelling and coordinating international humanitarian aid to fill gaps in capacity and resourcing national recovery efforts. However, central to disaster recovery, particularly in the immediate aftermath of disruption, are the ways that local people support each other (within and between communities). Disconnects between national and local recovery efforts are common and stand to inhibit effective responses. This study aims to understand horizontal, self-organised community-to-community support systems and communities’ post-disaster engagement with external aid. It draws from two different datasets: i) the observations collected through the emergency relief work led by the National Disaster Management Office in Vanuatu shortly after the 2023 twin tropical cyclones Judy and Kevin hit the country, as well as ii) the loss and damage survey led by the Vanuatu Fisheries Department to estimate the level of damage these cyclones caused in various regions of Vanuatu. Through this process, we highlight the social systems that enable community-to-community support, as well as potential opportunities for external-aid to support communities in a more efficient manner. Results reveal that community-to-community support is critical in the first weeks post-disaster. Recognizing the roles that different support networks play at different stages of disaster response is critical not only to improving people's and institutions' ability to bounce back from particular disruptions, but also in broader efforts to strengthen community resilience in the face of climate change.
