Aim of the project: Progressing paludicultures after centuries of peatland destruction and neglect

After Paris agreement and COP in Bonn: No Paris without Peatlands
• like other sectors, also agriculture must reduce GHG emissions 0
• peatland utilisation must adapt to climate change
• peat soils can only be used on the long run, if peat is fully preserved: reducing speed of peat decomposition is no solution
• peatlands can be highly productive without being arable land or grassland

• Raise water tablesmaximum GHG emissionsreduction
– Winter: flooded conditions (full inundation)
– Summer: medium groundwater table at +25 – -25 cm
• Measures:
– Remove amelioration systems
• Stop/reduce pumping
• Damming of ditches
• Slopy areas: dams on contour lines

Paludiculture!

Paludiculture*
• Cultivation of biomass on wet and rewetted peatlands
bog: peat moss
fen: Common Reed, Reed Canary Grass, Sedges, Alder, Cattail...
• Utilisation of biomass for industry and energy
peat conservation
reducing GHG emissions
replacing fossil resources
*„palus“ – lat.: swamp
