Paludiculture: Where Agriculture Meets Wetland Restoration
Paludiculture is an innovative agricultural practice that combines farming with wetland restoration. Instead of draining peatlands for traditional agriculture, paludiculture involves rewetting these ecosystems and growing crops suited to wet conditions, such as Sphagnum moss, reeds, cattails, sedges, and other native plants. This approach helps prevent the large annual release of greenhouse gases from drained peatlands, thereby contributing to climate change mitigation. It also allows continued use of the land for productive purposes while restoring ecosystem functions and providing environmental benefits like improved water quality, increased biodiversity, and ecosystem services.
The process typically involves rewetting drained peatlands and cultivating native plants that can be harvested sustainably. Sphagnum moss, for example, can be harvested for biomass and used as a renewable, peat-substitute in horticulture, reducing the need for extracting peat from wetlands. Other cultivated plants can be used in food, cosmetics, medicine, packaging, building materials, and energy.
The benefits of paludiculture include climate change mitigation through carbon preservation, conservation of peatland ecosystems, and the provision of raw materials for various industries. Currently, the market for paludiculture products is in early development stages, with some established markets for reed thatching, Sphagnum moss for horticulture, and construction wood. Other crops like hay or medicinal plants have regional markets or are still developing. Challenges remain for wider adoption, but ongoing research aims to overcome barriers and expand the market.
Overall, paludiculture offers a sustainable alternative to conventional agriculture on peatlands, aligning productive land use with environmental restoration and climate goals.

Key takeaways
- Paludiculture offers a sustainable land-use alternative to traditional drained peatland agriculture
- By cultivating native plants like Sphagnum moss, reeds, and sedges on rewetted peatlands, it promotes climate change mitigation through carbon sequestration and ecosystem restoration.
- Restoring peatlands through rewetting and paludiculture prevents further carbon release
- Preserving existing peat layers and avoiding drainage reduces the release of the 1.9 gigatonnes of CO2 equivalent that drained peatlands emit annually, supporting climate goals.
- Market development for paludiculture products is in early stages with regional variability
- Established markets exist for reed, Sphagnum mosses, and wood for construction, while crops like cattail and sedges are still in prototype and development phases, indicating potential for growth.
- Paludiculture provides multiple ecosystem services beyond climate mitigation
- It enhances water quality, water quantity, and biodiversity, contributing to broader environmental and ecological benefits.
- Challenges for widespread adoption include technical, economic, and market barriers
- While research continues, the application of paludiculture remains in the novel stage, requiring further development to overcome barriers to expansion.
