Why Nature-Based Solutions Matter for Our Planet’s Future
How nature-based solutions can save the planet is one of the most important questions scientists, governments, and communities are working to answer right now.
Here’s a quick summary:
- Protect ecosystems like forests, mangroves, and wetlands to lock in carbon and shield communities from extreme weather
- Restore degraded land — restoring 350 million hectares could remove 13–26 gigatons of greenhouse gases by 2030
- Manage working landscapes like farms and urban areas to cut emissions and cool cities
- Deliver co-benefits including cleaner water, stronger biodiversity, and safer coastlines
- Scale up investment from the current US$154 billion per year to the US$384 billion needed annually
These five actions form the backbone of what nature-based solutions (NbS) can do — and why they matter so much.
The climate crisis is urgent. Sea levels are rising. Extreme storms are getting stronger. Wildfires and droughts are becoming more frequent. And biodiversity is disappearing at an alarming rate.
Traditional fixes — seawalls, carbon capture machines, chemical fertilizers — are expensive, slow, and often create new problems. But nature already has tools that work. Mangrove forests. Peatlands. Coral reefs. Urban green spaces. These ecosystems have protected life on Earth for millions of years.
The challenge is simple: we need to stop destroying them and start restoring them — fast.
Research shows that high-quality NbS projects could mitigate up to 10 gigatonnes of CO₂ per year — roughly 27% of current global annual emissions. That’s not a small number. That’s a planet-changing opportunity.

What Are Nature-Based Solutions (NbS)?
To understand how nature-based solutions can save the planet, we first need to define what they actually are. According to the International Union for Conservation of Nature (IUCN), Nature-based solutions are actions to protect, sustainably manage, and restore natural or modified ecosystems. These actions address societal challenges effectively and adaptively, while simultaneously providing human well-being and biodiversity benefits.
A common point of confusion is the difference between traditional conservation and NbS. While traditional conservation focuses primarily on protecting wildlife and ecosystems for their own sake, NbS is explicitly human-centric. It uses healthy ecosystems as active infrastructure to solve pressing human problems, such as water insecurity, food shortages, disaster risks, and climate change.
To paint a clearer picture, let’s look at how these approaches differ when tackling environmental issues:
| Feature | Traditional Engineering (Gray Infrastructure) | Traditional Conservation | Nature-Based Solutions (NbS / Green Infrastructure) |
|---|---|---|---|
| Primary Goal | Solve a specific human problem (e.g., build a concrete seawall to stop flooding). | Protect species and habitats from human interference. | Address a societal challenge while actively benefiting biodiversity and people. |
| Methods Used | Concrete, steel, and industrial machinery. | Creating protected reserves, banning resource extraction. | Restoring wetlands, planting mangroves, establishing urban green roofs. |
| Flexibility | Rigid; expensive to upgrade or adapt once built. | Passive; relies on keeping nature isolated. | Adaptive; ecosystems grow, self-repair, and strengthen over time. |
| Co-Benefits | Minimal or negative (e.g., destroys local marine habitats). | High biodiversity value, but limited direct economic benefits for local communities. | High; improves water quality, stores carbon, supports local livelihoods, and boosts biodiversity. |
By shifting our focus from merely “saving nature” to “working with nature,” we unlock a powerful set of tools that can address multiple crises at once.
How Nature-Based Solutions Can Save the Planet through Climate Mitigation
The climate math is daunting. To limit global warming to well below 2°C—and ideally 1.5°C as outlined in the Paris Agreement—we must rapidly transition away from fossil fuels. However, emissions from heavy industry and agriculture cannot be driven to zero overnight. This is where atmospheric carbon dioxide removal becomes vital.
Nature-based solutions are the most efficient, cost-effective carbon capture technologies we have. Research shows that NbS and the broader land sector could contribute up to 30% of the climate mitigation needed by 2050. High-quality, high-integrity NbS projects have the potential to mitigate up to 10 gigatonnes of carbon dioxide (GtCO2) per year. This corresponds to approximately 27% of our current global annual emissions.
However, not all nature-based climate strategies are created equal. In an Expert review of the science underlying nature-based climate solutions | Nature Climate Change , researchers evaluated dozens of pathways across multiple biomes. They found that while established strategies like tropical forest conservation have robust scientific backing, other pathways (such as deep-water macroalgae cultivation) still face major uncertainties in greenhouse gas measurement and accounting. To make NbS a reliable pillar of global climate policy, we must prioritize pathways with high scientific certainty while actively researching the rest.
Restoring Forests and Peatlands: How Nature-Based Solutions Can Save the Planet
Forests and peatlands are the heavyweights of terrestrial carbon storage. Forests store immense amounts of carbon in their biomass and soils. Yet, human activities like deforestation and forest degradation continue to contribute around 10% of global CO2 emissions. Preventing this destruction is the single most effective action we can take to keep carbon out of the atmosphere.
Beyond protection, active restoration is key. By 2030, the restoration of 350 million hectares of degraded land and water ecosystems could remove 13 to 26 gigatons of greenhouse gases from the Earth’s atmosphere. This can be achieved through:
- Assisted Natural Regeneration (ANR): Allowing forests to regrow naturally by protecting surviving wild saplings and using natural seed dispersal from nearby wildlife.
- Reforestation and Afforestation: Planting native, diverse tree species rather than monoculture timber plantations, which lack ecological resilience.
- Peatland Re-wetting: Peatlands cover only 3% of the world’s land area but store twice as much carbon as all the world’s forests combined. When drained for agriculture, they dry out, decay, and release massive amounts of carbon. Re-wetting and restoring these soggy ecosystems keeps that carbon safely locked underground.
Just as we look to protect terrestrial ice sheets to prevent global disruptions—as we discuss in our deep dive into Everything You Need to Know About Antarctica’s Sudden Sea Ice Loss—we must treat our forests and peatlands as critical global infrastructure.
Blue Carbon: Coastal Ecosystems as Climate Shields
When we think of carbon storage, we often picture vast green forests. But some of the most efficient carbon sinks on Earth are actually wet, salty, and coastal. These are “blue carbon” ecosystems—primarily mangroves, seagrass meadows, and salt marshes.
These coastal areas capture and store carbon up to ten times faster than mature tropical forests per hectare. They bury carbon in their waterlogged soils, where a lack of oxygen prevents organic matter from breaking down and releasing CO2 back into the atmosphere. Protecting these areas prevents massive carbon “bombs” from detonating, while restoring them provides an immediate boost to our global carbon sink.
Climate Adaptation and Disaster Risk Reduction
Mitigating future warming is only half the battle; we also must adapt to the climate impacts that are already locked in. Extreme weather events are increasing in frequency and intensity, threatening lives and infrastructure.
Traditional engineering often relies on hard “gray” infrastructure, like concrete seawalls or storm drains, which can be brittle and expensive to maintain. Nature-based solutions offer a dynamic alternative. As highlighted in Nature-Based Solutions for Environmental Management: A Comprehensive Review of Effectiveness, Co-Benefits, and Monitoring , integrating green infrastructure can significantly reduce disaster risks while providing economic and ecological co-benefits.
Furthermore, reducing our reliance on synthetic, non-biodegradable materials helps limit the strain on these natural defenses. For instance, managing plastic waste effectively is a crucial part of protecting our waterways, a topic we explore in The Complete Guide to California’s New Plastic Recycling Rules Controversy.
Mangroves and Coral Reefs: Natural Coastal Defenses
Coastal communities face rising sea levels and increasingly severe storm surges. Rather than building massive concrete sea barriers that degrade local marine ecosystems, we can look to mangroves and coral reefs as natural defenses.
During the devastating 2004 Indian Ocean tsunami, villages in Tamil Nadu, India, that were protected by dense, intact mangrove forests experienced significantly less damage than those where the mangroves had been cleared. The numbers are staggering: a 100-meter belt of mangroves can reduce tsunami flow pressure by over 90 percent, depending on how dense the forest is. Mangroves act as giant, flexible shock absorbers, slowing down violent waves and trapping sediment to prevent coastal erosion.
Similarly, healthy coral reefs act as natural, self-healing breakwaters. They can dissipate over 97% of wave energy before it reaches the shore, protecting low-lying coastal communities from flooding much more effectively—and cheaply—than human-built concrete structures.
Urban Cooling and Green Infrastructure: How Nature-Based Solutions Can Save the Planet
Climate change isn’t just a rural or coastal issue; it is heavily felt in our cities. Because of the “urban heat island” effect, concrete and asphalt absorb heat during the day and radiate it at night, making cities significantly hotter than surrounding rural areas.
We can combat this by building greener cities. Implementing urban NbS includes:
- Green and Blue Roofs: Covering rooftops with vegetation (green roofs) or water-retaining systems (blue roofs) to insulate buildings, lower air temperatures, and capture stormwater.
- Urban Forests and Green Walls: Planting street trees and vertical gardens to provide shade, filter air pollution, and create stepping-stone habitats for urban biodiversity.
- Permeable Pavements and Rain Gardens: Replacing nonporous concrete with natural systems that allow rainwater to soak back into the ground, reducing urban flooding during heavy downpours.
These measures not only cool our cities and clean our air, but they also make urban spaces far more beautiful and livable for the people who call them home.
Overcoming Barriers to Scale and Finance NbS
Despite the clear benefits, nature-based solutions are not being deployed at the scale needed to address our global crises. The biggest obstacle? A massive funding gap.
Currently, global investments in NbS stand at approximately US$154 billion per year. To meet our climate, biodiversity, and land degradation targets, we must more than double this flow of capital, reaching US$384 billion annually.
Compounding this issue is where the money comes from. Currently, only 17% of total investments in NbS are funded by private finance. The remaining 83% comes from cash-strapped public budgets and multilateral development banks. To close the gap, we must incentivize private capital to view nature not as an externality, but as a valuable asset class.
This financial mobilization is a core pillar of the Kunming-Montreal Global Biodiversity Framework, which serves as a global roadmap to halt and reverse biodiversity loss. As detailed in the scientific paper Frontiers | Nature Positive: halting and reversing biodiversity loss toward restoring Earth system stability (also available via the Potsdam Institute for Climate Impact Research ), achieving a “Nature Positive” future by 2030 requires us to stop treating nature destruction as a business-as-usual practice and start actively investing in the preservation of intact biomes.
Frequently Asked Questions about Nature-Based Solutions
Can nature-based solutions replace deep emission cuts?
Absolutely not. Nature-based solutions are a vital complement to decarbonization, not a substitute for it. If we do not rapidly phase out fossil fuels and make deep cuts to greenhouse gas emissions across all sectors, rising global temperatures will eventually trigger widespread ecosystem collapse. If our forests burn down in massive wildfires and our oceans become too warm for coral reefs to survive, our natural carbon sinks will turn into carbon sources. We must pursue both aggressive technological decarbonization and nature-based strategies simultaneously.
What is the difference between conservation and NbS?
Traditional conservation focuses on preserving biodiversity, wild species, and pristine habitats for their intrinsic value, often by limiting human access. Nature-based solutions, on the other hand, are designed to address specific human and societal challenges—such as flood risk, urban heat, or water pollution—by actively managing, restoring, or working alongside ecosystems. NbS aims for a “win-win” scenario where both human communities and local biodiversity benefit.
How do we measure the effectiveness of NbS projects?
Measuring the success of NbS requires robust Monitoring and Evaluation (M&E) frameworks. Instead of just counting how many trees are planted, modern projects use an “intervention-pathway-endpoint” indicator logic chain. This involves tracking concrete biophysical metrics (such as soil moisture, water flow rates, and canopy cover) alongside social metrics (like community health and local economic income). Long-term carbon accounting is also monitored using satellite telemetry, drone mapping, and field soil samples to ensure that stored carbon remains safely locked away.
Conclusion
At its core, how nature-based solutions can save the planet is about restoring the delicate balance of our biosphere. From coastal mangrove belts shielding communities from tsunamis to green roofs cooling our concrete jungles, working with nature is our most effective path toward long-term Earth system stability.
