    The CINDERELLA project:Paludiculture for GHG emissions mitigation in peatlands

    Wendelin Wichtmann

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

    Cinderella Syndrom

  • 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

  • Drainage based management of peatlands

    Subsidies• Direct payments

    • Renewable energy (biogas, biofuel)

    • Agri-environment-climate schemes

    • Organic farming

    In Germany peatland agriculture causes annually a climatedamage of € 3.6 billion, and gets 300 million EU-grants (CC)

  • Use of peatlands and GHG emissions

  • Rewetting

    • 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

  • Natural succession after rewetting


  • peat preservation, climate protection + agriculture:


  • 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

  • Wet grasslands

    Reed canary grass (Phalaris arundinacia)

    productivity: 3.5 – 15 t DM/ha*a

    emissions: 12 t CO2eq/ha*a

  • Common Reed (Phragmites australis)

    productivity: 3 – >25 t DM/ha*a

    emissions: 10 t CO2eq/ha*a

  • www.kuleuven-kulak.be

    Sedges (Carex spp.)

    3 – 12 t DM/ha*a

    0 – 8 t CO2 -eq / ha*a

  • Cattail (Typha spec.)

    Productivity : 5 - 22 t DM/ha*a

    Emissions: 10 - 15 t CO2eq/ha*a

  • Black Alder (Alnus glutinosa)

    productivity: 3 – 10 t DM/ha*a

    emissions: 0 t CO2eq/ha*a

  • General aims of CINDERELLA

    • Increase knowledge

    • Make paludiculture accessible to farmers and land authorities

    promote paludiculture

  • • Nutrient retention

    • Characterisation of plant species

    • Economics

    • productivity/site conditions

    • Yield and nutrient uptake

    • Surveys/incentives

  • Field days and stakeholder meetings

    Consultancy on all levels urgently necessary

  • rrr2017 Conference

    • 200 participants from

    • 26 countries

    Conference statement

  • – Recognition of paludiculture as agriculture

    – Stop counterproductive incentives

    – Application of the polluter pays principle

    – Rewarding ecosystem services

    – Accounting of GHG emissions from peatland use in the reporting for UNFCCC

    Adjustment is required on national and on EU level

    Framework conditions for paludiculture

  • Peatlands must be wet: for the climate, for the land, for

    the people, for ever…
