The Alliance of Regional Collaboratives for Climate Adaptation (ARCCA) is a network of leading regional collaboratives and allies from across California that work together to advance adaptation statewide and increase local capacity to build community resilience. Through ARCCA, adaptation practitioners connect with peers across the state to exchange knowledge, engage in targeted problem-solving, and implement joint campaigns, effectively breaking down silos across sectors and jurisdictions.
