As the field of climate adaptation continues to evolve, so too does our understanding of how to secure investments that support climate adaptation strategies and resilient communities. Many local jurisdictions across California have started incorporating climate change considerations into local planning efforts, however many jurisdictions face significant barriers to implementation due to financing and funding challenges. Given the relative newness of the field of practice, there are a limited number of guidance resources currently available. 

In an effort to support this emergent area, the Governor's Office of Planning and Research, through the Integrated Climate Adaptation and Resilience Program (ICARP), developmed a climate adaptation finance book, authored by Jesse M. Keenan from Harvard University. Climate Adpatation Finance and Investment in California is available as both an e-book and as a PDF.

Additionally, research projects funded through California’s Fourth Climate Change Assessment  provide further insight into the local government barriers to implementation – including financing and funding.
