As a statewide network bringing together leading thinkers and doers of climate adaptation at all levels of society, ARCCA provides critical infrastructure to advance adaptation in California.

ARCCA is a robust network of leading regional collaboratives – each encompassing a diverse group of public agencies, nonprofits, universities, and private sector companies – working together to build resilience to climate change impacts throughout California. ARCCA also includes affiliate members working at the statewide, national, and/or international level to advance adaptation. ARCCA provides critical support to adaptation practitioners, including:

• Coordination between State, regional, and local goals and activities;
• Supporting for regional collaboratives to build effective local responses; and
• The exchange of best practices and replicable strategies to accelerate actions.
