Nature-based solutions (NbS) are generally effective and often superior to conventional methods for adapting to climate change impacts, though evidence on cost-effectiveness and global equity is limited. This resource management research insight is drawn from a 2020 study published in Global Change Biology. Using Systematic mapping of evidence, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing for climate adaptation, consider nature-based solutions as a primary strategy, but be mindful of specific ecosystem types and the need for more comprehensive evidence, especially concerning economic viability and equitable global application.

Key Findings
- 01Most nature-based interventions in natural or semi-natural ecosystems effectively ameliorated adverse climate impacts.
- 02Interventions in created ecosystems showed trade-offs, often reducing water availability.
- 03Nature-based interventions were frequently as effective or more effective than alternative interventions.
- 04Substantial evidence gaps exist, particularly regarding cost-effectiveness and integrated assessments of broader outcomes.
- 05Evidence is biased towards the Global North, despite higher vulnerability in the Global South.
Application
Design takeaway
When designing for climate adaptation, consider nature-based solutions as a primary strategy, but be mindful of specific ecosystem types and the need for more comprehensive evidence, especially concerning economic viability and equitable global application.
How to apply
When developing climate adaptation plans or projects, conduct a thorough review of existing nature-based solutions relevant to the specific context, paying attention to reported synergies and potential trade-offs, and identify areas where further research or pilot studies are needed to fill evidence gaps.
Project actions
- 01When researching solutions for environmental challenges, look for studies that compare different approaches, including natural ones.
- 02Be aware of where research comes from and consider if it applies to your specific project's location and context.
- 03Identify and discuss the limitations of the evidence you find, especially regarding cost and broader impacts.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +First global systematic map of evidence on NbS for climate adaptation.
- +Comprehensive analysis of synergies, trade-offs, and comparisons with alternative interventions.
Limitations
The study relies on existing published research, which may have its own inherent biases and limitations. The definition and scope of 'nature-based solutions' can also vary, affecting comparability.
Reliability & validity
The systematic mapping approach enhances reliability by standardizing evidence retrieval and analysis. Validity is supported by the broad scope of the search and the inclusion of diverse intervention types, though the reliance on reported findings introduces potential for publication bias.
Think critically
Given the evidence gaps, how can designers and researchers ethically and effectively advocate for and implement nature-based solutions in regions with limited supporting data?
Design Principles
"Integrate ecological processes into design solutions for enhanced resilience and multi-benefit outcomes, while critically evaluating evidence limitations."
This research highlights the significant potential of leveraging natural systems for climate resilience. Designers and engineers can integrate these findings into project planning to advocate for and implement more sustainable and effective adaptation strategies, moving beyond purely engineered solutions.
What This Means for Your Design
Using nature, like forests or wetlands, to help us deal with climate change is usually a good idea and often works better than just building things. However, we don't have enough proof about how much it costs or how well it works everywhere, especially in poorer countries that need it most.
How to use in your project
- 1.Cite this study when discussing the effectiveness of nature-based solutions compared to traditional engineering approaches in your design project.
- 2.Use the findings on trade-offs to justify design choices or identify areas for further investigation in your design process.
