Presentation of Mark Sutton, from CEH, at Food, Fertilizers and Natural Resources Conference by Fertilizers Europe

  1. 1. ENA Launch11-15 April 2011EdinburghInternational Conference“Nitrogen & Global Change”ENA Authorship 200 experts, 21 countries & 89 organizationsScientifically independentprocesswww.nine-esf.org/ENA
  2. 2. Nitrogenin the News• International TV & Press Coverage• ENA summary in Nature• ENA 4-minute video on “Youtube” The Sun, Scotsman, Guardian, La Monde, VOK, Nature 14 April 2011
  3. 3. Objectives of the European Nitrogen Assessment• To review current scientific understanding of nitrogen sources, impacts and interactions across Europe,• Taking account of current policies and the economic costs and benefits, as a basis to• Inform the development of future policies at local to global scales.
  4. 4. Scaling up of issues through the European Nitrogen AssessmentUpscaling & Integration European Nitrogen policies & future challenges Part E Water Air Greenhouse Ecosystems Soil quality quality balance & biodiversity quality Part D Integrating nitrogen fluxes at the European Scale Geographic variation in terrestrial nitrogen budgets across Europe Nitrogen flows from Atmospheric transport European watersheds to & deposition of nitrogen coastal marine waters in Europe Nitrogen flows Nitrogen flows Part C and fate in rural and fate in urban landscapes landscapes. Nitrogen flows in farming systems across Europe. Nitrogen processing in the biosphereProcesses &Mechanisms Part B

  12. 12. Gothenburg Protocol: Options to reduce ammonia loss from fertilizers• Ammonium bicarbonate: ban (since 1999)• Urea: require low emission methods by e.g. 30% compared with reference (under negotiation) – Urease inhibitors – Coated pellets – Immediate incorporation – Substitute with alternative fertilizer• Ammonium phosphate and sulphate on high pH soils (under negotiation)• Focus on improving nitrogen use efficiency helps to reduce other N losses and impacts.

  14. 14. 5 priorities for ammonia in revision of the UNECE Gothenburg Protocol (1=highest priority)1. Low emission techniques for land spreading of cattle/pig/poultry manures and mineral fertilizers2. Animal feeding strategies, inc phase feeding3. Covers on new slurry stores4. Farm N balance on demonstration farms5. Low emission new pig & poultry housing
  15. 15. Outlook• Progress in UNECE and EU negotiations• Maximizing the policy benefits and the role of market leaders• Measuring the benefits of voluntary approaches• Linking agricultural, water, air, climate, biodiversity and soil policies• Life-cycle stewardship for nitrogen
