Types of Nature-Based Solutions

Nature-based solutions include varied practices that can be applied at many different scales, for example, to an entire watershed or a specific site. The common thread is that nature-based solutions mimic natural processes and offer diverse benefits.

Below, we've organized nature-based solutions into three categories:

Watershed or landscape-scale practices build interconnected systems of natural areas and open space. They require long-term planning and coordination. Examples include land conservation and greenways.

Neighborhood or site-scale practices manage rainwater where it falls to reduce stormwater runoff. They can often be built into a site or neighborhood without much extra space. Examples include permeable pavement and tree trenches.

Coastal practices stabilize the shoreline, reduce erosion and buffer the coast from storm impacts. While many watershed and neighborhood scale practices work in coastal areas, coastal systems are designed to support coastal resilience.

Examples of Nature-Based Solutions

Waterfront parks in coastal areas can be intentionally designed to flood during extreme events, reducing flooding elsewhere.

Waterfront parks can also absorb the impact from tidal or storm flooding and improve water quality.

Bike trails and nearby greenspace can absorb the impact from flooding. They also reduce the urban heat island effect.

Bike trails provide recreational opportunities and connect people to nature.

Living shorelines stabilize a shore by combining living components, such as plants, with structural elements, such as rock or sand.

Living shorelines can slow waves, reduce erosion, and protect coastal property.

Coral reefs serve as a natural breakwater. They absorb wave energy and protect the coast from erosion and flooding.

Coral reefs support about a quarter of the ocean’s biodiversity. They can also provide recreational opportunities and support local economies.

Oysters are often referred to as “ecosystem engineers” because of their tendency to attach to hard surfaces and create large reefs made of thousands of individuals.

In addition to offering shelter and food to coastal species, oyster reefs buffer coasts from waves and filter surrounding waters.

Coastal wetlands are found along ocean, estuary, or freshwater coastlines.

They are often referred to as “sponges” because of their ability to absorb wave energy during storms or normal tide cycles.
