Community resilience. Sustainable landscapes. These terms are becoming more commonplace and heard more often. Why? Because our collective and growing knowledge and experience tells us that global climate change is the impetus for increased catastrophic weather events.
What do these terms mean, exactly?
Taken one at a time, community resilience is the ability to anticipate risk, limit impact, and bounce back rapidly through survival, adaptability, evolution, and growth in the face of turbulent change, as defined by the Community and Regional Resilience Institute.
Turbulent change can include severe threats such as sea level rise, hurricanes, wildfires, drought, economic down-turns, social unrest, and other disruptions.
Environmental threats make up just one component—though significant—to the whole of turbulence that impacts resiliency, and designing landscapes that are sustainable is one way to help manage them.
The American Society of Landscape Architects defines sustainable landscapes best: “Sustainable landscapes are responsive to the environment, re-generative, and can actively contribute to the development of healthy communities. Sustainable landscapes sequester carbon, clean the air and water, increase energy efficiency, restore habitats, and create value through significant economic, social and, environmental benefits.”
It’s worth noting too, that a sustainable landscape is designed to be both attractive and to require minimal resources in terms of cost and ongoing maintenance.

A sustainable landscape can include:
- Reduction of stormwater run-off through the use of bio-swales, rain gardens and green roofs and walls
- Reduction of water use in landscapes through design of water-wise garden techniques (sometimes known as xeriscaping)
- Bio-filtering of wastes through constructed wetlands
- Landscape irrigation using water from showers and sinks (known as gray water)
- Integrated Pest Management (IPM) techniques for pest control
- Creating and enhancing wildlife habitat in urban environments
- Energy-efficient landscape design in the form of proper placement and selection of shade trees and creation of wind breaks
- Permeable paving materials to reduce stormwater run-off and allow rain water to infiltrate into the ground and replenish groundwater rather than run into surface water
- Use of sustainably harvested wood, composite wood products for decking and other landscape projects, as well as use of plastic lumber
- Recycling of products, such as glass, rubber from tires and other materials to create landscape products such as paving stones, mulch and other materials
- Soil management techniques, including composting kitchen and yard wastes, to maintain and enhance healthy soil that supports a diversity of soil life
- Integration and adoption of renewable energy, including solar-powered landscape lighting
That’s a lot. Let’s take a closer look at just two aspects of a sustainable landscape.
FIRST: Enhancing wildlife habitat. Habitat loss, and the corresponding loss of biodiversity, can be curbed when we connect properties into networks of attractive, wildlife-friendly neighborhoods, cities, and regions. Starting with the home landscape, fragmented habitats can be rewoven together, creating spaces that are not only healthier for wildlife but also for people.

SECOND: Reduction of stormwater run-off. In many communities, rain water flows into combined stormwater and sewer systems, which channel both sewage and rainwater together through underground pipes to central treatment facilities. Storms can quickly overrun these combined systems, leading to flooding with pollutant-laden water and even backed up sewage.

When these approaches are viewed with a wide scope and on a large scale, the potential impacts of sustainable landscaping are pretty powerful. At the same time, it’s important to recognize that change often starts on a small scale. And there might be no better place to start than in your own back yard.
