To address climate change’s impact on the environment-health nexus, community collective action groups have emerged in Sitka, Alaska that focus on changing food systems, conservation, and disaster risk reduction. These groups fill gaps where formal institutions, such as governments and businesses, provide inadequate action. These community-based organizations, often non-profit and informal in nature, face classic collective action issues, such as inadequate funding, mobilization challenges, and relying on incentivizing members to participate. This research aims to understand how volunteer-based, local groups self-organize to address climate change and its environmental and health impacts, through local natural resource-based collective action. The methods utilized are semi-structured interviews with members and representatives of community-based environmental groups in Sitka, Alaska, to analyze the group’s activities, operations, challenges, and successes. The ongoing results show that groups are particularly successful in filling gaps in the provision of food, the conservation of certain species, and monitoring local environmental changes. Local interests and disinterests in natural resources, health, and climate change emerge, which create both opportunities and challenges for the groups’ successes. Furthermore, the COVID-19 pandemic has challenged community engagement efforts as it has exacerbated existing divisions in the community.
