As the climate crisis worsens, the world is scrambling for scalable, affordable, and effective ways to reduce greenhouse gas emissions and protect communities from rising climate risks. While technology continues to play a vital role, there’s a powerful, time-tested tool right beneath our feet and above our heads: nature.
Nature-based solutions (NbS) are gaining global recognition as some of the most effective and multi-benefit strategies for combating climate change. From restoring forests to protecting wetlands and reviving coral reefs, these solutions leverage the power of ecosystems to absorb carbon, regulate temperatures, reduce disaster risks, and support biodiversity.
In this article, we’ll explore what nature-based solutions are, how they work, where they’re succeeding, and why they are essential to a sustainable future.

What Are Nature-Based Solutions?
Nature-based solutions (NbS) are actions that protect, sustainably manage, or restore natural ecosystems to address major societal challenges, such as climate change, water security, food supply, and disaster resilience.
They include:
- Conservation: preserving tropical rainforests.
- Restoration: reforesting degraded land.
- Sustainable use of resources: agroforestry or sustainable wetlands management.
These solutions are grounded in ecology but deliver social, economic, and environmental benefits, often at lower cost and higher resilience than engineered alternatives.
“NbS are actions to protect, sustainably manage, and restore natural or modified ecosystems, that address societal challenges effectively and adaptively, simultaneously providing human well-being and biodiversity benefits.”
Nature as a Climate Mitigation Powerhouse
Natural ecosystems are vital carbon sinks, absorbing and storing carbon from the atmosphere. The destruction of these systems, however, releases massive amounts of CO₂, accelerating global warming.
| Ecosystem | Role in Climate Mitigation |
|---|---|
| Forests | Absorb ~2.6 billion tons of CO₂ per year; critical for carbon sequestration |
| Peatlands | Store more carbon than all other vegetation types combined |
| Mangroves | Sequester up to 4 times more carbon than terrestrial forests |
| Oceans & Seagrass Meadows | Store 25% of the world’s carbon; essential in blue carbon ecosystems |
Nature-Based Solutions for Climate Adaptation
NbS are not just about removing CO₂, they also help communities adapt to climate impacts like extreme weather, rising sea levels, and droughts. Below are some examples of NbS for Adaptation:
- Mangrove forests protect coastal communities from storm surges, erosion, and tsunamis.
- Wetlands absorb floodwaters and recharge groundwater, reducing disaster risks.
- Urban green spaces reduce heat island effects and improve air quality in cities.
- Agroforestry enhances crop resilience and soil fertility in drought-prone regions.
Co-Benefits: More Than Just Climate
One of the greatest strengths of NbS is that they offer multiple benefits at once. Unlike most engineered solutions, which are single-purpose, nature-based solutions support entire ecosystems and communities.
| Benefit | Impact |
|---|---|
| Climate mitigation | Carbon capture and storage |
| Climate adaptation | Risk reduction from droughts, floods, storms |
| Biodiversity | Habitat protection and species recovery |
| Human health | Cleaner air, water, and green spaces |
| Livelihoods | Eco-tourism, sustainable fishing, agroforestry income |
| Food and water security | Improved soil, water retention, and pollination |
Challenges to Scaling Nature-Based Solutions
Despite their promise, NbS are underutilised and underfunded. They are often side-lined in favour of technological solutions or large-scale infrastructure projects. Some of the key barriers to NbS are:
- Short-term economic pressures such as land for agriculture or development.
- Lack of valuation of ecosystem services in economic systems.
- Unclear land rights and governance, especially in Indigenous territories.
- Greenwashing risks, where companies mislabel NbS efforts without measurable impact.
Integrating Nature-Based Solutions Into Policy
To scale up NbS, integration into national climate plans (NDCs), land-use strategies, and development frameworks is crucial. Fortunately, momentum is growing:
- 130+ countries mention NbS in their climate commitments under the Paris Agreement.
- Initiatives like the UN Decade on Ecosystem Restoration (2021–2030) are rallying global support.
- Financial tools such as green bonds, carbon credits, and blended finance are helping fund ecosystem restoration.
Frequently Asked Questions (FAQs)
Are nature-based solutions just about planting trees?
No. While reforestation is a key component, NbS includes conserving wetlands, restoring coral reefs, adopting sustainable farming, and more.
How are NbS different from engineered solutions?
NbS use natural systems to address problems, often with co-benefits for biodiversity, livelihoods, and resilience, unlike single-purpose gray infrastructure.
Do NbS really work at scale?
Yes. Projects like Brazil’s Atlantic Forest restoration and China’s reforestation have impacted millions of hectares and reduced carbon emissions.
Can cities use NbS?
Absolutely. Urban green infrastructure such as green roofs, wetlands, tree canopies, is a growing area of NbS.
How can I support NbS personally?
Support local conservation, reduce consumption, donate to verified restoration projects, and advocate for NbS in climate policies.
Conclusion
We are not separate from nature, we are part of it. And in the fight against the climate crisis, nature is one of our most effective, affordable, and immediate allies.
Nature-based solutions can sequester carbon, protect biodiversity, reduce disaster risk, and support livelihoods, if we protect, fund, and scale them responsibly. As we look toward a climate-resilient future, restoring the planet may be our most powerful act of survival and solidarity.
