Rewetting peatlands is a simple way to fight climate change, keeping carbon locked in the soil, reducing emissions, and helping prevent fires by maintaining wet conditions.
Fight Climate Change with Peatland Restoration
Estimated reading time: 6 minutes
Earth often has a carbon problem. Too much gas will heat up our planet. But one of the smart solutions sits under our feet. Peatlands are really wet swamps. They will store massive amounts of carbon inside them. Dr. Hans Joosten is a scientist who found this solution. People often call him “Bogfather”. He often rewets the drained peatlands. This will stop the carbon emissions instantly. This is like a cheap and fast fix. No fancy machines are required for this activity. Science often proves this will work well. In this article, let’s deep dive through this innovation to combat climate change.
Fight Climate Change with Peatland Restoration: Key Takeaways
- Peatlands, known as nature’s carbon vaults, can significantly store carbon and help fight climate change.
- Rewetting drained peatlands can stop carbon emissions instantly and prevent wildfires.
- This restoration technique requires no advanced technology and has immediate climate benefits.
- Unlike tree planting, peat restoration stores carbon faster, is more permanent, and uses less land.
- Awareness and policy changes are essential for increasing peatland restoration efforts globally.
What Are Peatlands and Why Do They Matter to fight climate change?
Nature’s carbon vaults
Peatlands are often soggy and acidic wetlands. Dead plants often pile up there on the land. They do not rot and destroy completely. This process will lock up the carbon inside the soil. The carbon will stay trapped in the soil for thousands of years.
Massive storage capacity
To enumerate this further, peat will cover only 3% of the Earth’s land. But it will only hold up to 30% of all the soil carbon. This will double the carbon present in all trees on the Earth surface.
The damage we cause
Farmers often drain the peat for all crops. This will dry the soil. Oxygen and carbon together will turn into carbon dioxide. This process will create upto 5% of global human-caused emissions.

How Rewetting Peatlands fights Climate Change
Simple technique, big results to fight climate change
Scientists often block drainage ditches. This will raise the water table for our environment. Wet moss will return to the surface of the Earth. The peat will start storing all the carbon in the soil again. No high-tech tools are required for this purpose. This will help to fight climate change.
Emissions will stop instantly
Prior to this rewetting, all this drained peat will slowly lose all the carbon. After all of that happens, those emissions will stop immediately. This peat will become a carbon sink again. It will store all the carbon year after year. (Günther et al., 2020)
Methane is not a problem
This wet peat will release all of the methane gas. But this methane gas emission will stop after a few years. The carbon storage benefit is much larger than that. Over 20 years, rewetted peat will cool the climate altogether.
Prevents deadly fires
Drained peat is highly considered flammable. It will burn easily during the droughts season. These fires will release tons of smoke and carbon. Re-wetting this will keep the peat wet. It cannot be burnt anymore.
Why Peat Restoration Beats Tree Planting for ?
Speed matters a lot.
Firstly, trees take 20 years to absorb this significant amount of carbon. In contrast, peat will start storing all the carbon immediately in soil after rewetting it. Therefore, we do not have to wait for 20 years.
Permanence is better.
While trees can easily burn with forest fires, and drought can also kill the forests, releasing all their stored carbon, peat is different. Since peat is always wet, it cannot catch fire easily.
Less land needed.
Moreover, peat will store more carbon per square meter than forests. As a result, you will need less land for the very same benefit. This, in turn, allows room for further food production as well.
Double climate benefit.
Additionally, wet peat helps reflect sunlight, which cools the ground further. Conversely, dry peat helps absorb heat. By rewetting the peat, we both store carbon and reduce global warming.
List: Top 5 Benefits of Peatland Restoration to fight climate change
- Stops carbon emissions immediately after rewetting.
- Prevents wildfires that release toxic smoke.
- Filters drinking water naturally.
- Reduces flood risk by holding rainwater.
- Protects rare species like cranes and otters.
What’s more? These five benefits make peat a star climate tool. Indeed, no other natural system checks so many boxes.
All things considered, this solution is cheap and scalable. With this we can fight climate change. Thus, we can deploy it now.
Why Aren’t We Doing This Everywhere?
Firstly, lack of awareness: most people do not know about peatlands. They often think trees are the only solution. However, peat is better at storing carbon. Hence, we need to spread this knowledge. Secondly, policy barriers: some governments subsidize draining peat by paying farmers to dry the land. We must flip these incentives and pay farmers to rewet instead. Thirdly, slow adoption: restoration projects take time to plan, and local communities must agree. Nevertheless, the science is clear: it works everywhere.
Finally, cost is not the issue: rewetting one hectare costs about $500, while a carbon capture machine costs millions. Therefore, peat is the cheaper option.
Conclusion:
Peatlands are nature’s hidden climate tool. They store massive carbon and cost little to restore. The science is clear, rewetting works. We just need to act now, stop draining, start rewetting, and cool the planet. It is that simple. These steps can help us to fight climate change.
Frequently Asked Questions (FAQs)
Does rewetting peat release methane?
Yes, initially, but the methane stops after a few years. Importantly, the carbon storage benefit is much larger. Over 20 years, rewetted peat cools the climate.
Can you farm on rewetted peat?
Yes, you can grow wet crops like cranberries or sphagnum moss. This practice, called paludiculture, keeps the carbon locked in place.
How much peatland has been restored so far?
Globally, about 500,000 hectares have been restored. However, that is a small fraction. We need to restore 100 million hectares to make a big climate dent (Leifeld & Menichetti, 2018).
Is peat restoration expensive?
No, it is cheap. Restoring one hectare costs $500–1,000, which is far less than direct air capture machines
