Through no-till and cover-crop practices, the soil health management system an Ohio farmer practices restore and re-carbonize soil. The no-till practices increase crop yields by 36-44%, sequesters around 960 kg of carbon per hectare per year, and reduce fertilizer and herbicide use by 75 percent.

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.

Coastal Louisiana contains around 40% of the wetlands in the continental United States and accounts for approximately 80% of the nation’s wetland loss due to sea-level rise, storm surges, and subsidence. This project restored 1,600 hectares of bald cypress (Taxodium distichum) forest at Pointe-aux-Chenes Wildlife Management Area.
The Great Dismal Swamp, a 45,000-ha state and federally protected Coastal Plain peatland located on the border of North Carolina and Virginia, was degraded after centuries of drainage and logging. To restore its ecosystem structure and function, US FWS installed two adjustable water control structures (WCS).
The Portland Water District conducted a green-gray analysis to compare natural versus gray infrastructure for an EPA-granted filtration system to improve Sebago Lake's water quality. They ultimately chose to invest in forest-based natural infrastructure, including restoring riparian buffers and reforesting riparian zones.
The Herring River Restoration Project in Massachusetts will replace the restrictive dike at the mouth of the river with a bridge that will allow tidal water to flow freely between the river and Wellfleet Harbor. This will restore the biodiverse, productive, estuary that existed pre-dike construction.
Five years after the Allen Road Fire, the U.S. government established the Pocosin Lakes National Wildlife Refuge in the North Carolina cost to restore the ditched, dried, and burned peatlands and convert them back into carbon sinks. Refuge managers are working in a 19-year effort to construct an equally ingenious hydrologic system.
The Dixon Water Foundation utilizes rotational grazing regimes to rehabilitate grasslands at Mimms Ranch in the Chihuahuan Desert, which was previously degraded by overgrazing. Rotational grazing mimics historical bison movements, allowing pastures long periods of rest and recovery after short disturbances. This promotes soil health and reduces runoff and erosion.
The Dixon Water Foundation employs grazing techniques that mimic historical bison movements to rehabilitate the Chihuahuan Desert grassland from the impacts of overgrazing, which have led to increased erosion, runoff, reduced aquifer recharge, and carbon sequestration. Such rotationally grazed practices improve soil health as cattle fertilize soil with manure and break up surface to allow seeding and water infiltration.
The Nature Conservancy conducted research in the Saz-Zim Bog with the mission to measure carbon and methane emissions from the bog in order to learn more about its potential for mitigating climate change and the best approach for restoration. Long misunderstood and unappreciated, peatlands are gaining recognition for the carbon storage and other ecosystem benefits they provide.
