Farming Flood Tolerant Crops on Peatlands: Nature and Climate Benefits

Wetland farming stores more carbon while restoring wildlife habitat

Researchers at the RSPB and University of Cambridge have confirmed that growing crops on waterlogged peatlands cuts greenhouse gas emissions, brings back wetland species, and keeps farms productive. The practice, known as paludiculture, involves cultivating flood-tolerant plants like bulrush, common reed, and sphagnum moss on peat soils with deliberately high water tables.

This approach tackles a pressing problem. When peat soils are drained for conventional farming, they release huge amounts of stored carbon. UK peatlands hold around 3.2 billion tonnes of carbon. Once exposed to air through drainage, that carbon escapes as carbon dioxide, contributing significantly to national emissions.

Paludiculture reverses this process. Keeping water levels high prevents peat decomposition. At the same time, farmers can still grow commercially useful crops adapted to wet conditions. Field trials in Somerset, led by FWAG South West and the RSPB, have tested these systems on working agricultural land. Early results show measurably lower emissions compared to drained peat farming, alongside visible improvements in habitat quality.

The research builds on a comprehensive 2024 review funded by the Natural Environment Research Council. That study examined paludiculture projects worldwide, analysing both small-scale and commercial operations. It found consistent benefits: reduced emissions, higher biodiversity, and alignment with ten United Nations Sustainable Development Goals. The findings suggest this farming method works across different geographies and farm types.

Somerset trials demonstrate practical viability despite yield differences

Current UK trials focus on three main crop types. Typha, commonly known as bulrush, produces biomass suitable for insulation materials, thatching, and animal bedding. Common reed serves similar markets, particularly for traditional roof thatching. Sphagnum moss, once established, can be harvested for horticulture, replacing peat extracted from pristine bogs.

In 2025, researchers hand-harvested experimental plots to measure yields accurately. The crops produced less biomass per hectare than conventional farming on drained peat. However, the trials proved the concept works. Farmers can grow and harvest these plants with adapted equipment. Consequently, research teams are now testing mechanical harvesters designed for wet ground conditions.

Biodiversity monitoring revealed significant gains. Bird surveys on Typha plots recorded species abundance comparable to natural wetlands. This matters because intensive drainage has eliminated most wetland habitat from UK farmland. As a result, specialist birds like snipe, lapwing, and reed bunting have declined sharply. Paludiculture sites create habitat that bridges the gap between productive farmland and nature reserves.

Parallel research on solar farm sites reinforces these findings. The RSPB compared solar installations managed for nature against standard designs. Sites with wetland features and diverse vegetation supported three times more birds. Species like corn bunting and yellowhammer, which have suffered steep population crashes on conventional farmland, thrived in these managed landscapes. Dr Joshua Copping from the RSPB noted that solar farms managed well for nature could make an important contribution to the long-term survival of farmland birds.

Government commits £85 million to peat restoration by 2030

The UK government’s Environmental Improvement Plan 2025 allocates £85 million specifically for peat restoration and paludiculture development by 2030. This represents a substantial policy shift toward recognising wetland agriculture as a legitimate land use option. Previously, most peatland funding supported only complete rewilding or traditional conservation management.

The Paludiculture Exploration Fund entered its second round in 2023, distributing £5 million across twelve demonstration projects. These trials test different crop species, water management techniques, and harvesting equipment. A further funding round opens in June 2026, targeting both dedicated wetland cropping and conventional farming adapted to higher water tables. This flexibility acknowledges that not all peat soils suit complete rewetting, yet modest water level increases still cut emissions substantially.

Defra has registered over fifteen paludiculture projects across England. The largest concentrations appear in East Anglia and Somerset, regions with extensive lowland peatlands historically drained for agriculture. Moreover, the government set a target to restore 40,000 hectares of degraded peatland by April 2030. Paludiculture will contribute to this goal alongside other restoration methods.

Additional funding streams support farmers making the transition. The Co-op Foundation’s Carbon Innovation Fund added £3.5 million in 2024 specifically for wetland farming pilots. Skills grants of up to £20,000 per year help farmers and contractors learn new cultivation and harvesting techniques. These grants recognise that paludiculture requires different knowledge than conventional farming, particularly around water management and specialist crop handling.

The RSPB’s Centre for Conservation Science coordinates this research through the Cambridge Conservation Initiative. This partnership links university scientists with conservation practitioners, ensuring research addresses real-world farming challenges. Field trials feed directly into policy development, creating an evidence base for expanding paludiculture nationally.

Flood-tolerant farming cuts emissions while maintaining farm income

Climate change is making conventional peat farming increasingly difficult. Winter flooding now regularly inundates fenland fields, sometimes for months. Subsidence caused by drainage lowers land levels, worsening flood risk. In some areas, peat soils have dropped by several metres since drainage began. This creates a vicious cycle where farms become harder and more expensive to protect from water.

Paludiculture offers a way out. Instead of fighting against water, farmers work with it. Flood-tolerant crops grow productively in conditions that would destroy wheat, potatoes, or salad vegetables. Consequently, land that becomes marginal for conventional farming can remain economically productive. This matters particularly for tenant farmers who cannot simply abandon difficult fields.

Carbon finance provides another income stream. The UK Peatland Code allows landowners to generate verified carbon credits from peatland restoration. Paludiculture projects can access these markets while maintaining agricultural production. In contrast, complete rewilding typically ends farming income entirely, making it unviable for many landowners.

Subsidence reduction brings measurable economic benefits. Continuing drainage requires constant pumping, regular ditch maintenance, and periodic land regrading. As peat shrinks, drainage infrastructure needs expensive upgrades. Raising water tables stops subsidence, cutting these maintenance costs significantly. Additionally, reduced subsidence lowers flood risk for neighbouring properties and infrastructure.

Water quality improvements offer broader catchment benefits. Drained peat soils release nutrients and dissolved organic carbon into waterways, degrading water quality and increasing treatment costs. Rewetted peatlands filter runoff naturally, improving downstream water quality. Water companies have shown interest in paludiculture as part of catchment management strategies to reduce treatment costs.

Market development remains the critical challenge. Unlike wheat or potatoes, wetland crops lack established supply chains and processing facilities. Early adopters face uncertainty about where they can sell their harvest and at what price. However, demand exists. Sphagnum moss can replace peat in horticulture, addressing an environmentally damaging industry. Typha and reed biomass suits insulation manufacture, a growing market as building regulations tighten. Thatching remains a skilled craft with consistent demand for quality materials.

Professor Andrew Balmford from Cambridge University has examined the economics of land use change more broadly. His research on land sparing showed that converting some farmland to habitat while intensifying production elsewhere delivers biodiversity and climate benefits at half the cost to taxpayers compared to spreading conservation thinly across all farmland. This finding supports targeted paludiculture on the most difficult-to-drain peat soils.

Current evidence confirms paludiculture reduces peatland emissions

Several key findings emerge from the research programme so far:

• Field measurements show paludiculture sites emit significantly less carbon dioxide and nitrous oxide than drained peat farmland, with the greatest reductions occurring where water tables stay within 10 centimetres of the surface year-round.
• Biodiversity surveys recorded wetland bird abundance on paludiculture plots matching levels found in nature reserves, representing a substantial improvement over conventional peat farming which supports very few wetland specialists.
• Hand-harvested trial yields in 2025 proved lower than conventional crops but demonstrated commercial viability, with ongoing machinery development expected to improve harvest efficiency and reduce costs.
• The 2024 NERC-funded review analysed global paludiculture evidence and confirmed benefits across climate mitigation, biodiversity recovery, water quality, flood management, and rural employment in both small-scale and commercial systems.
• Government funding through the Environmental Improvement Plan 2025 commits £85 million to peatland restoration by 2030, with the Paludiculture Exploration Fund supporting practical trials and the target of restoring 40,000 hectares including paludiculture contributions.
• Economic analysis confirms revenue potential through crop sales and carbon credits under the Peatland Code, though market development and processing infrastructure require further investment to achieve widespread viability.

Wetland cropping suits land facing increased flood risk

For many UK farms, paludiculture represents adaptation rather than revolution. Farmers already struggling with waterlogged fields recognise they need alternatives to conventional cropping. Drainage systems installed decades ago no longer cope with current rainfall patterns. Pumping costs have risen while crop yields on wet soils have fallen.

Paludiculture gives these farmers productive options. Rather than abandoning difficult fields or spending heavily on upgraded drainage, they can switch to crops adapted to wet conditions. This maintains farm income and land values while solving a practical farming problem. It also positions farms to benefit from environmental payment schemes that increasingly reward carbon storage and habitat creation.

The approach suits different farm scales. Smallholders can integrate small paludiculture plots into mixed farming systems, perhaps using harvested reed for their own livestock bedding. Larger farms can dedicate whole fields to wetland crops, potentially supplying regional processing facilities. This flexibility helps spread adoption across different farm types and regions.

Skills development forms a crucial part of the transition. Most farmers and contractors lack experience with wetland crops and high water table management. Therefore, training programmes funded through the Paludiculture Exploration Fund help build this expertise. Early adopters share practical knowledge about planting techniques, water control, and harvest timing. This peer-to-peer learning accelerates adoption by reducing risk for later entrants.

Integration with broader land management creates additional benefits. Farms combining paludiculture with areas of complete rewetting and continued conventional farming on better-drained soils achieve diverse income streams and risk spreading. This mixed approach often proves more resilient than single land use strategies. It also creates landscape-scale habitat mosaics that support wider species ranges.

The RSPB’s Cumbria Connect project demonstrates this integrated approach at scale. The programme combines peatland restoration, sustainable farming, and community engagement across a large landscape. Paludiculture trials within this project test how wetland farming fits alongside upland grazing and woodland creation, providing evidence for landscape-level planning.

Tenant farmers face particular challenges and opportunities. Many farm on short-term agreements that make long-term land use changes difficult. However, paludiculture can improve rather than reduce land values by solving drainage problems and generating environmental income. Landlords increasingly recognise that degraded peat soils represent liabilities, while restored peatlands offer stable long-term returns through carbon finance and environmental schemes. This alignment of interests may encourage more collaborative tenancy agreements supporting paludiculture adoption.

Peatland farming reform supports net zero and nature recovery targets

UK climate commitments require substantial emission reductions from land use. Currently, drained peatlands contribute roughly 4% of total UK greenhouse gas emissions despite covering only 3% of land area. This makes peatland the most emission-intensive land use per hectare. Consequently, addressing peat emissions represents one of the most cost-effective climate actions available.

Paludiculture offers a practical path forward that maintains rural economies. Complete peatland rewilding removes land from production, raising food security concerns and rural opposition. In contrast, paludiculture keeps land productive while cutting emissions dramatically. This political and practical viability may prove crucial for achieving peatland restoration targets.

Nature recovery plans similarly depend on creating wetland habitat at scale. The UK has lost over 90% of its original wetlands, driving declines in specialist species. Small nature reserves cannot sustain viable populations alone. Therefore, integrating habitat into working farmland becomes essential. Paludiculture creates exactly this integration, producing economically valuable crops while supporting wetland biodiversity.

Water management benefits extend beyond individual farms. Landscapes with more wetland storage reduce downstream flood peaks, protecting urban areas and infrastructure. This flood management service has economic value, though payment mechanisms remain underdeveloped. Future policy may reward paludiculture farmers for these catchment services alongside carbon and biodiversity benefits.

The research underpinning these developments continues to expand. Field trials now entering their fifth to eighth years provide increasingly robust data on long-term productivity, emission reductions, and ecological change. This evidence base supports policy development and gives farmers confidence in paludiculture viability. It also helps refine best practice guidance for different soil types, climates, and farming contexts.

Businesses seeking support with carbon reduction and net zero planning should consider how land use fits into their strategies. Companies with supply chains touching agriculture may find paludiculture offers opportunities for scope 3 emission reductions. Those exploring nature-based solutions can examine whether peatland restoration aligns with their environmental commitments.

Organisations requiring compliance support for carbon reporting should account for land use emissions accurately. Peatland holdings represent material emission sources requiring specific calculation methods. Understanding paludiculture options helps businesses develop credible reduction plans rather than relying solely on offsetting.
