Through a capacity to evolve to keep pace with climate change, these approaches can impart self-sustaining and cost-efficient long-term protection in addition to serving as biodiverse, carbon sinks . Nature-based adaptation is generally less expensive and strengthens over time, as compared with built infrastructure which erodes with time  . Analysis of the impacts of Hurricane Sandy determined that communities located behind wetlands experienced 20% less damage . Coral reefs are providing 544 million USD yr-1  and mangroves 22 billion USD yr-1 in property protection for coastal communities in the USA and Mexico . By 2030, flooding from changes in storms, SLR  and increases in built infrastructure in the US Gulf Coast may result in net economic losses of
