The article presents studies on rock detention structures (RDS) at four sites, supporting their recognition as nature-based solutions (NbS) due to their potential for climate mitigation and adaptation. Decision-makers’ understanding of these impacts and commitment to funding is essential for effective climate change strategies. RDS, observed across the U.S.-Mexico border, provide multiple ecosystem services and have proven effective over centuries in managing water and restoring landscapes. The article emphasizes RDS’s scalability and long-term benefits, including flood mitigation and carbon sequestration.
RDS serve as sustainable solutions that protect and restore ecosystems compared to traditional green infrastructure, which focuses on passive water retention. However, their implementation requires significant investment, with costs estimated at $73 million for treating all Federal and Tribal riparian areas in Arizona. Despite installation costs, the potential economic returns could yield over 1,000 job-years and substantial economic output. RDS can improve water quality, biodiversity, and community resilience to climate impacts.
The author argues for RDS as NbS in the context of climate change by highlighting their long-lasting impact and the economic benefits they offer in restoration and job creation, thus promoting a restoration stewardship economy. The commentary calls for broader recognition and investment in RDS-NbS as part of strategies to address the challenges posed by climate change in vulnerable regions.
