An ad hoc committee of the National Academies of Sciences, Engineering, and Medicine will organize a two-day workshop on the benefits, applications, and opportunities of natural infrastructure (i.e., aspects of the natural landscape such as coastal wetlands, beaches, dunes, marshes, mangrove forests, municipal green infrastructure, and living shorelines)which can provide multiple benefits, e.g., for natural hazard risk reduction and ecosystem functioning. The workshop will convene experts from federal, state and/or local government, the private sector, the philanthropic community, academia, and nongovernmental organizations to discuss natural infrastructure applications and efficacy in areas such as natural hazard resilience, climate change adaptation, and sustainable, multi-purpose infrastructure. Participants will also explore opportunities to link the benefits of natural infrastructure across geographic scales and multiple objectives, and to advance and mainstream natural infrastructure and nature-based solutions in public and private engineering practice. A proceedings of a workshop in brief will be prepared by a designated rapporteur. Following the publication of the proceedings, a dissemination event will be held to discuss natural infrastructure in context of more comprehensive and equitable evaluation of benefits from nature based solutions.
