What Are Nature-based Solutions (NbS)? Why They Matter to Today's Architects and Landscape Designers.
What Are Nature-based Solutions (NbS)? Why They Matter and Why Every Modern Designer Should Understand Them
As the climate crisis continues to intensify, its impacts have become too great for any individual, community, or nation to address alone. Climate change is now one of the defining challenges of our time, fundamentally reshaping the way we design our cities, buildings, and landscapes.Today, design is no longer judged solely by aesthetics or functionality. It must also create resilience—the ability of our built environment to adapt to changing climate conditions while protecting both people and nature. This is where Nature-based Solutions (NbS) have emerged as a vital design approach that every architect, landscape architect, engineer, and urban designer should understand and embrace.
Nature-based Solutions (NbS) are actions that protect, sustainably manage, and restore natural or modified ecosystems to address major societal challenges, including climate change, water security, biodiversity loss, and natural disasters. By working with nature rather than against it, NbS provide benefits for both human well-being and healthy ecosystems.
The term Nature-based Solutions was first introduced by the World Bank in 2008 in its report Biodiversity, Climate Change, and Adaptation: Nature-based Solutions from the World Bank Portfolio. The report emphasized that biodiversity conservation should not be viewed solely as an environmental objective, but also as a key strategy for climate change adaptation and sustainable economic development. It highlighted the importance of protecting natural ecosystems as part of the global response to climate change.
This marked a fundamental shift in design thinking—from relying primarily on grey infrastructure, such as concrete structures and engineered drainage systems, to embracing green infrastructure that works in harmony with natural processes. Unlike conventional engineering solutions, green infrastructure is living, adaptive, and capable of providing long-term environmental, social, and economic benefits.
For today's designers, understanding Nature-based Solutions is no longer optional. It is an essential approach to creating resilient cities, restoring ecosystems, improving quality of life, and building a more sustainable future for generations to come.
Why Should Designers Understand Nature-based Solutions (NbS)?
In architecture and landscape design, Nature-based Solutions (NbS) shift the role of vegetation from being merely an aesthetic feature to becoming an integral part of a building's performance and ecological function.
Understanding NbS enables designers to move beyond creating beautiful spaces to designing resilient ecosystems. This transformation is driven by three key advantages:
- Climate Adaptation
Natural systems are inherently more adaptable to environmental change than conventional built infrastructure. They can effectively manage stormwater, reduce urban heat, improve air quality, and enhance climate resilience.
- Long-term Cost-effectiveness
Nature-based systems generally require lower maintenance and offer greater long-term value when properly designed and managed. They also reduce reliance on energy-intensive engineering solutions while extending the lifespan of surrounding infrastructure.
- Multiple Co-benefits NbS not only address technical and environmental challenges but also improve mental well-being, increase biodiversity, enhance public spaces, and create healthier, more livable communities.
Applying Nature-based Solutions Across Environmental Design Urban Planning & Landscape Architecture
At the urban scale, planners and landscape architects can apply Nature-based Solutions as a key strategy for developing resilient green infrastructure that protects, restores, and enhances the urban environment.
One of the best-known examples is the Sponge City concept, where permeable landscapes are designed to absorb, store, and naturally filter stormwater, reducing surface runoff and urban flooding.
Examples include:
- Permeable Surfaces – Designing pavements, parking areas, parks, and public spaces with permeable materials that allow rainwater to infiltrate the ground, helping reduce flash flooding. A notable example is Benjakitti Forest Park in Bangkok, which incorporates constructed wetlands to retain, treat, and manage stormwater.
- Constructed Wetlands – Creating engineered wetland systems that use aquatic plants and beneficial microorganisms to naturally treat wastewater before it is discharged into rivers or other natural water bodies.
- Ecological Corridors – Connecting parks and green spaces into continuous ecological networks, allowing wildlife, birds, and pollinating insects to move safely through urban environments while preserving biodiversity.
Architecture: Integrating Buildings with Natural Ecosystems
Architects can apply the principles of Nature-based Solutions (NbS) to reduce the environmental impact of buildings while improving energy efficiency. Rather than treating nature as an ornamental element, NbS integrates natural systems into the building itself, allowing architecture to work in harmony with the environment.Examples of NbS at the building scale include:
External Shading & Living Envelopes
Incorporating vegetation into building façades and external shading systems helps reduce heat gain and improve the Overall Thermal Transfer Value (OTTV). Combined with natural ventilation strategies, these living building envelopes can significantly reduce cooling loads and energy consumption. For example, rooftop rainwater storage systems can also help lower roof surface temperatures and improve thermal performance.Green Roofs & Green Walls
Green roofs and living walls provide passive cooling by reducing heat transfer into buildings, lowering indoor temperatures, and improving energy efficiency. They also help mitigate the Urban Heat Island effect while enhancing urban biodiversity and creating more comfortable outdoor environments.Bio-based Materials
Selecting renewable, nature-based construction materials with low embodied carbon—such as cross-laminated timber (CLT), mycelium-based materials, and rammed earth—helps reduce carbon emissions while supporting sustainable building practices.Natural Ventilation & Daylighting
Designing buildings to maximize natural airflow and daylight reduces dependence on air conditioning and artificial lighting. Orienting buildings according to prevailing winds and solar exposure creates healthier, more energy-efficient, and environmentally responsive spaces.Interior Architecture: Enhancing Well-being Through Nature
Within interior environments, Nature-based Solutions (NbS) focus on improving occupants' health, well-being, and the relationship between people and the built environment. Rather than viewing nature as a decorative element, NbS integrates natural systems and biophilic principles into interior spaces to create healthier, more comfortable, and more productive environments.Applying Nature-based Solutions in Interior Architecture
Biophilic Design & Phytoremediation Biophilic design goes beyond simply placing plants indoors. It incorporates natural elements such as vegetation, water features, natural materials, textures, daylight, and visual connections to outdoor landscapes to strengthen the relationship between people and nature. These design strategies have been shown to reduce stress, improve cognitive performance, and enhance overall well-being.Daylighting & Circadian Lighting
Maximizing natural daylight helps regulate the human circadian rhythm, supporting healthier sleep patterns, improved mood, and increased productivity. Thoughtful daylighting design also reduces dependence on artificial lighting and lowers building energy consumption.Indoor Air Quality (IAQ)
Indoor vegetation can contribute to healthier indoor environments through phytoremediation, while living wall systems integrated with mechanical ventilation can help improve air quality by filtering airborne particles, including PM2.5, and reducing volatile organic compounds (VOCs).Circular & Bio-based Materials
Selecting furniture, finishes, and interior materials made from renewable or bio-based resources—such as bio-composites, recycled materials, or biodegradable products—supports a circular economy while reducing environmental impacts throughout a building's life cycle.Nature-based Solutions in International Green Building Standards
Today, Nature-based Solutions (NbS) are no longer considered an alternative design approach—they have become an integral part of leading international green building standards. These certification systems recognize the environmental, social, and economic benefits of working with nature and provide measurable performance criteria for sustainable design.SITES (The Sustainable SITES Initiative)
Among global sustainability standards, SITES places the strongest emphasis on Nature-based Solutions. It promotes landscape designs that enhance ecosystem services, including soil restoration, on-site stormwater management, habitat creation, and the use of native plant species to improve biodiversity.LEED (Leadership in Energy and Environmental Design)
NbS contribute to several LEED credit categories, particularly Sustainable Sites (SS) through heat island reduction strategies, and Water Efficiency (WE) by incorporating natural stormwater management techniques and Low Impact Development (LID) practices.WELL Building Standard
The WELL Building Standard focuses on human health and well-being. Nature-based SolutionsConclusion: From Aesthetics to Measurable Long-Term Value
The fundamental principle of Nature-based Solutions (NbS) is a shift in perspective—from designing for aesthetics alone to designing for long-term system sustainability. Rather than treating nature as a decorative feature, NbS views natural systems as functional infrastructure that delivers measurable environmental, social, and economic value.
A Life Cycle Perspective
One of the greatest strengths of NbS is its long-term performance. Unlike conventional engineered materials that deteriorate over time, well-designed natural systems become more resilient, productive, and valuable as ecosystems mature. Healthy vegetation, restored soils, and functioning water systems continue to improve environmental performance throughout their life cycle.
Measurable Performance
The benefits of Nature-based Solutions can be quantified using clear performance indicators. At the urban scale, NbS can be evaluated by measurable outcomes such as:
- Temperature Reduction – Lowering surface and ambient air temperatures, helping mitigate the Urban Heat Island effect.
- Stormwater Management – Reducing stormwater runoff volume through infiltration, detention, and natural water retention.
- Carbon Sequestration – Capturing and storing atmospheric carbon dioxide (CO₂), contributing to climate change mitigation.
Creating Long-Term Economic Value
Nature-based Solutions also generate tangible economic benefits. They can reduce energy consumption, lower maintenance and flood recovery costs, extend the service life of infrastructure, and increase property values by creating healthier, more attractive, and higher-quality public spaces.
Looking Ahead
Perhaps the most important message for today's designers is that Nature-based Solutions are not simply about adding more plants to a project. They are about designing natural systems that function alongside people and the built environment.
Designers who understand and apply NbS create projects that deliver far more than visual appeal. They develop resilient, high-performing environments that address the needs of clients while generating lasting benefits for communities, ecosystems, and future generations. In doing so, they help shape cities that are not only more beautiful, but also healthier, more sustainable, and better prepared for the challenges of a changing climate.
