This article is about how farming wet or rewetted lands—called paludiculture—could be one of the smartest and most sustainable moves we can make today.
“We don’t have to choose between farming and the environment—we just need to rethink where, how, and what we grow.”— The Economic Botanist
Farming isn’t just about growing food—it’s part of a much bigger story that connects land, water, people, and the climate we all share. That story is shifting, and one of the newest chapters is called paludiculture.
You’ve probably heard of sustainable farming and climate-smart agriculture, but paludiculture takes things a step further. It’s about farming in wet places—like peatlands and marshes—without draining them. It blends ecology, innovation, and traditional knowledge into a way of growing that protects nature while still producing valuable crops.
In this article, we’re diving into the world of wetland farming and paludiculture—from the plants that thrive in soggy soils to the ways this approach is helping restore ecosystems and fight climate change. Whether you’re a grower, a landowner, a climate advocate, or just curious about what the future of farming could look like, this guide will give you a fresh perspective on a greener, wetter way to grow.

What is paludiculture?
Let’s break it down: palus is Latin for “swamp.” So paludiculture is essentially wetland agriculture. Unlike traditional farming, which often drains wetlands to grow crops, paludiculture keeps wetlands wet—and turns them into productive, climate-friendly farmland.
This approach is all about growing suitable crops in peatlands, marshes, and other wet landscapes without drying them out. Why does that matter?
Because draining peatlands releases huge amounts of carbon into the atmosphere. Peatlands are like big carbon vaults. When we keep them wet, they stay locked. When we dry them out for farming or development, they release their stored carbon and become greenhouse gas hotspots.
So, with paludiculture, we can:
Farm sustainably
Protect biodiversity
Reduce carbon emissions
Support local economies
Adapt to climate change
Pretty good for something that looks like a soggy field, right?
Why North America is ready for paludiculture
We have the land
North America has millions of acres of peatlands, wetlands, and flood-prone agricultural land—especially in:
Canada’s Hudson Bay Lowlands, Boreal regions, and Maritime bogs
U.S. regions like the Great Lakes, Gulf Coast, Alaska, and the Prairie Pothole Region
Much of this land has been drained in the past for agriculture, and now we’re seeing the consequences: erosion, emissions, and declining productivity. Some of this land is even being abandoned.
Instead of writing it off, what if we could farm it differently?
We need the climate solutions
Peatlands cover only 3% of the Earth’s land, but store over 30% of all soil carbon. When we drain them, they release CO₂, methane, and nitrous oxide—all major greenhouse gases.
Paludiculture helps by:
Avoiding further emissions
Rebuilding peat (yes, it can grow back if we stop disturbing it)
Creating carbon sinks with crops like sphagnum moss and cattails
And we have the opportunity
With rising consumer interest in sustainable food, peat-free gardening, and low-emission materials, paludiculture crops could help supply the next generation of climate-smart products.
Plus, many Indigenous and local communities in North America have been stewards of wetland environments for generations. Paludiculture can honor that knowledge while offering new economic pathways.
Crops that thrive in wetland farming
You might be surprised at just how many paludiculture crops can grow in wet or rewetted soils. Here are a few that are especially promising in North America:
1. Cattail (Typha spp.)
Found naturally across wetlands in Canada and the U.S.
Can be used for insulation, paper, bioplastics, and even fuel
Harvested in pilot projects (like in Manitoba) for both phosphorus removal and biomass energy
2. Sphagnum Moss
Grows in northern bogs, especially in Canadian peatlands
Excellent for horticulture and growing media
A promising peat-free alternative as traditional peat becomes unsustainable
3. Wild Rice (Zizania spp.)
Culturally significant to Indigenous nations, especially in the Great Lakes
Grown in natural wetlands—could become a leading example of eco-friendly, culturally rooted food production
4. Blueberries and Cranberries
Already grown in wet soils, especially in parts of Maine, Quebec, and British Columbia
Paludiculture offers an even more sustainable production model
5. Reed Canary Grass, Sedges, and Reeds
Great for fodder, bioenergy, and erosion control
Could help support regenerative grazing practices
Growing markets for paludiculture products
Here’s where things get exciting. Paludiculture isn’t just an ecological fix—it’s a market opportunity.
According to research from the UK, wetland farming can supply raw materials for many fast-growing sectors. Here’s how that translates to North America:
Horticulture and Growing Media
Rising demand for peat-free potting mixes and sustainable gardening products
Sphagnum moss and wetland fibers could help fill that gap
Bioenergy and Biomass
Crops like cattails and reeds can be turned into:
Pellets for heating
Biofuels
Digestible biomass for anaerobic digestion
Construction Materials
North America’s green building movement is booming
Wetland fibers can be used for:
Insulation boards
Particleboard
Sustainable packaging
Fodder and Livestock Feed
In wetter regions of Canada and the northern U.S., low-input grazing could work well with reed or sedge-based fodder
Food and Nutraceuticals
Wild rice, blueberries, cranberries, and other wetland foods can command premium prices
Medicinal wetland plants like marshmallow root or water pepper could enter specialty health markets
Carbon Markets and Ecosystem Services
As carbon trading systems expand, farmers may be able to get paid to keep their land wet through credits or conservation incentives
Policy support and challenges in North America
Paludiculture isn’t mainstream yet—but there are signs of support building.
In the United States:
The USDA and NRCS are exploring climate-smart agriculture strategies, including wetland restoration.
Private carbon markets and programs like EQIP (Environmental Quality Incentives Program) could begin including paludiculture in their portfolios.
In Canada:
Provinces like Manitoba and Quebec are experimenting with wetland biomass.
The Canadian Sphagnum Peat Moss Association is also exploring more sustainable harvest methods and alternatives.
Challenges to Watch:
Lack of infrastructure for processing wetland crops
Regulatory hurdles—for example, wetland protections sometimes make farming difficult, even when it’s sustainable
Market awareness—many buyers still don’t know what paludiculture is (yet)
Lessons from the UK and around the world
In the UK, Germany, and the Netherlands, paludiculture has seen real investment and market growth. The UK’s Katy Ross estimated demand for over 180,000 hectares of rewetted land to meet market needs.
Examples worth watching:
Germany: Reeds and cattails turned into home insulation through local cooperatives
The Netherlands: Sphagnum farming on rewetted peatlands as a commercial peat alternative
Indonesia: Tropical paludiculture using crops like sago and kangkong to restore degraded peatlands
These models show us it’s possible—with the right incentives and public awareness.
The future of wetland farming
Paludiculture isn’t just a trend—it’s a bridge between environmental restoration and productive land use. Here's how it can scale:
Localized processing
Mobile biomass pelletizers or moss dryers make it easier for farmers to process products on-site
Indigenous and community partnerships
Respecting traditional knowledge while opening up co-managed business models
Certification and branding
Paludiculture-based products could carry eco-labels to signal sustainability to consumers
Education and storytelling
The more people understand the value of wetlands, the more support there’ll be for rewetted farming systems
And remember, many of these changes don’t need to happen overnight. Even small-scale paludiculture pilots can help test methods, grow markets, and show what’s possible.
The Bottom Line
Paludiculture is one of the most promising ways to farm for the future. It turns wet or rewetted land into something valuable—without damaging ecosystems, accelerating climate change, or draining our resources (literally).
In North America, we’ve got the land, the climate challenges, and the market opportunities. Now we need to start connecting the dots.
Whether you’re a farmer, policymaker, student, or someone who just really likes wetlands—this is your moment to think differently about farming. Wet doesn’t mean wasted. It might just mean what’s next.
