Department of the Interior Nature-Based Solutions Roadmap
Abstract
This comprehensive resource, created in collaboration with the US Department of the Interior, is a first-of-its-kind reference for implementing nature-based solutions (NBS). Nature-based solutions are actions to protect, sustainably manage, or restore natural or modified ecosystems to address societal challenges—including climate change—in ways that help people and the environment. Examples cited in the Roadmap range from urban stormwater and runoff management to prescribed burns to living shorelines to restoration of various ecosystems.
Nature-based solutions require planning and design specific to each site and strategy being employed, but some principles and considerations apply in every case. The first section of the Roadmap offers information on these cross-cutting principles and considerations, including community engagement, application of Indigenous Knowledges, equity and environmental justice, funding sources, and common barriers.
The bulk of the nearly 500-page Roadmap is devoted to details 29 individual NBS strategies. Each strategy summary contains these elements:
- A list of likely benefits, including climate threat reduction, socioeconomic and ecological benefits
- Example projects from throughout the United States
- Links to additional tools, training and resources for project planning, implementation and monitoring
- Details about site suitability, how the strategy is implemented on the ground, and operations and maintenance needs
This living document is part of the Nature-Based Solutions project at the Nicholas Institute for Energy, Environment & Sustainability. Explore more NBS content, including fact sheets on each of the strategies in the Roadmap.

Sara Mason
Sara Mason joined the Ecosystem Services Program at the Nicholas Institute for Energy, Environment & Sustainability as a policy associate after graduating from Duke with a master’s degree in environmental management. Her work focuses on the interdisciplinary nature of biodiversity conservation and how that can be leveraged to engage the public and policy makers in conservation efforts. Prior to joining the Nicholas Institute, Sara worked in ecological field research and endangered animal rehabilitation.

Lydia Olander
Lydia Olander is a program director at the Nicholas Institute for Energy Environment & Sustainability at Duke University and adjunct professor at the Nicholas School of the Environment. She works on improving evidence-based policy and accelerating implementation of climate resilience, nature-based solutions, natural capital accounting, and environmental markets. She leads the National Ecosystem Services Partnership and sits on Duke’s Climate Commitment action team. She recently spent two years with the Biden administration at the Council on Environmental Quality as Director of Nature based Resilience and before that spent five years on the Environmental Advisory Board for the US Army Corps of Engineers. She is a fellow of the American Association for the Advancement of Science (AAAS) and widely published researcher. Prior to joining the Nicholas Institute, she spent a year as an AAAS Congressional Science and Technology Fellow working with Senator Joseph Lieberman on environmental and energy issues. She was a college scholar at Cornell University and earned her Master of Forest Science from Yale University and Ph.D. from Stanford University.
