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.

Drought, grazing, and monoculture have led to low infiltration and high erosion in New Mexico during the monsoon season. With funding from the New Mexico Healthy Soils Program, the owners of C-B Ranch and Esquibel Ranch are restoring infiltration and vegetation using keyline design techniques, such as swales and rip lines.

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.

State/Territory:

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.

To restore the rare riparian wetlands at the Rio Yaqui Basin, USFWS purchased conservation easements to protect water resources and increase connectivity of riparian and upland habitats. USFWS built trust with a local coalition of ranchers who support private land conservation. Two conservation easements were purchased: the 7,000-acre 99-Bar Ranch and the 13,713-acre Bar Boot Ranch.

Non-native Boer and Lehmann lovegrasses threatened the native grasslands at the Appleton-Whittell Research Ranch (AWRR). AWRR staff began experimenting with treatments of lovegrass in the late-1990s to discover effective methods to protect and rehabilitate native grasslands. Chemical treatment (glyphosate + colorant + surfactant) was the only method that was effective.

Wildlife Corridors LLC purchased a 189-lot, high-density housing development to create a single conservation easement project. They preserved the wildlife corridors and managed the land use for restoration and recreation. These wildlife corridors serve as linkages to enhance genetic flow and biodiversity of wildlife species.
