Assessing Cost Effectiveness of Coastal Climate Adaptation Solutions in California: CoSMoS Adapts


California’s coast faces significant climate change challenges that threaten the coastal economy, critical infrastructure, communities, and a rich natural system. In response, State agencies and local communities have been scaling up adaptation efforts, increasingly embracing a “pathway” approach, but they have expressed a lack of tools to evaluate local adaptation options and the distribution of benefits at local and regional scales, especially nature-based solutions (NBS). Adaptation planning to date has also raised difficult questions about equity and justice, such as the harm to communities through displacement, or the distribution of costs and benefits of adaptation investments. The proposed research aims to address these gaps by developing (1) local coastal climate hazard information; 2) tools for evaluating adaptation strategies and pathways, and (3) assessments of coasts and benefits and their spatial and equitable distribution.
