Nature-Based Solutions Case Study Search

This database contains over 400 implementations of nature-based solutions. Use the filters to identify the case studies most relevant to you.

While all cases here exemplify applications of NBS strategies, they were gathered from various sources and not all were written using the framing of nature-based solutions. To qualify as a nature-based solution, a project must provide benefits to both people and nature. In some instances, the human benefits are present but not emphasized in the case write ups; these cases were included because they still provide useful information to learn from.

Crystal Springs Creek runs directly through the city of Portland, Oregon. This creek was disconnected from its floodplain from urban and agricultural development and channelization, leaving the water too warm for important salmonid species. This project restored 730 meters of the creek, improved salmonid habitat, and created a thriving urban park.
