NATURANCE is a 3.5-year Horizon Europe project which examines the technical, financial and operational feasibility and performance of solutions built on a combination of disaster risk financing and Nature-based solutions investments

Global review of peer-reviewed articles:
“71 % of studies indicated that NbS have consistently proven to be a cost-effective approach to mitigating hazards and 24 % of studies found NbS cost-effective under certain conditions.”
“Studies comparing the cost-effectiveness of NbS and engineering-based solutions for mitigating certain hazards showed that NbS are no less effective than engineering-based solutions. Among these studies, 65 % found that NbS are always more effective in attenuating hazards compared to engineering-based solutions and 26 % found that NbS are partially more effective.”

December 2024 - Report by White House Office of Science and Technology Policy (Biden Harris Administration).
This report integrates academic and practitioner perspectives to evaluate the effectiveness of 23 nature-based solutions to address hazards and to provide ecosystem services. It also provides recommendations, both to systematically consider nature-based solutions and to accelerate research, innovation and adaptive learning.

National Academies (US) Practice Forum
Video Recordings: https://www.nationalacademies.org/event/43697_02-2025_national-practice-forum-on-nature-based-solutions
The National Academies of Sciences, Engineering, and Medicine (NASEM), the Network for Engineering With Nature (N-EWN), and the University of California Santa Cruz (UCSC) Center for Coastal Climate Resilience convened a national forum focused on the practice of nature-based solutions. The two-day event was held February 4-5, 2025, at the National Academies' Beckman Center in Irvine, California.
The forum brought together national leaders and practitioners to discuss innovations in the application of nature-based solutions (NBS) for hazard mitigation and climate adaptation. Discussions focused on overcoming challenges in scaling NBS and finding collaborative, equitable solutions. The forum followed the 2024 N-EWN National Policy Forum conducted in collaboration with the National Academies in Washington DC.
Forum objectives included:
Showcase full-scale implementation of nature-based solutions and lessons learned
Promote equity and justice in hazard mitigation and adaptation projects
Identify challenges and opportunities to meet objectives for risk reduction and conservation
Strengthen partnerships to accelerate the pace of NBS implementation
