Nature-based Solutions to Address Flood Risks in Coastal Communities Report Series

April 29, 2025 45 pages Climate Change Ecosystems

Flood-risk management is a major concern for coastal communities, particularly when considering sea-level rise caused by climate change. Nature-based solutions (NBS) have the potential to meet many flood-risk management objectives while also providing social, environmental, and economic co-benefits.

This series of guidance documents was designed to support the uptake of NBS in coastal communities across Canada, Mexico and the United States, by providing decision makers and practitioners with practical information and guidance related to NBS co-benefits, retrofitting existing infrastructure using NBS, and monitoring NBS. The documents synthesize significant previous work, incorporate insights from an interdisciplinary community of practitioners gathered through intersectoral workshops, and propose new, practical decision frameworks and processes. They also include case studies from the three countries to provide real-world context and emphasize key concepts throughout the reports.

This report series was published as part of the CEC project Nature-based Solutions to Address Flooding in Coastal Cities.
