Binational Resilience for a Sustainable Future

One Coastal Community is a collaborative initiative dedicated to promoting the expansion of resilience capacities of both natural and social-urban coastal systems, seeking to strengthen ecosystem sustainability, research, and community-driven actions. Our stakeholder network includes leading researchers, nonprofit organizations, and funding partners, interested in reducing vulnerability to climate change.
