  1. Results of the environmental assessments with the CCAT-Tool J.P. Lesschen, J. Kros, W. de Vries and B.S. Elbersen Alterra, Wageningen UR CCAT end-user meeting, 16 April 2009

  2. Outline • MITERRA-Europe model • Measures Nitrate Directive • Results environmental assessments • Final remarks

  3. Changes in management Costs of compliance CAPRI: Market response 1) Changes in cropping shares 2) Change in livestock type/number MITERRA: emissions to: 1) Water 2) Air 3) Soil MITERRA-Europe in CCAT tool Cross compliance obligations

  4. MITERRA-Europe • A tool for integrated assessment of N (C and P) emissions from agriculture in EU-27 at Member State and regional levels (NUTS2) • Developed for the European Commission • Based on information from CAPRI and RAINS/GAINS • Simple/rapid model; uniform approach for EU-27 • Scenario analysis • Outputs: NH3, N2O and CH4 emission; N balance, NO3 leaching and N runoff; P balance and soil carbon stocks

  5. N outputs: harvested crop Atmosphere Atmosphere NH3 N2O NOX N2 NH3 N2O NOX N2 N inputs: N fertilizer BNF, N deposition Crop production:- Crop type - Cropped area - Management Animal production: - Animal species - Animal number - Management N outputs: milk, meat, egg feed manure NH4+ NO3- DON Npart NH4+ NO3- DON Npart Groundwater & surface waters MITERRA-Europe

  6. Nitrate Directive • Aims at “to decrease water pollution caused or induced by nitrates from agricultural sources and prevent further such pollution” • No more than 50 mg NO3/liter in groundwater • Applicable in Nitrate Vulnerable Zones (NVZ)

  7. Nitrate Directive measures • Balanced N fertilizer application • Maximum manure N application (170 kg N/ha) • Limitation to N application in winter and wet periods • Limitation to N application on sloping grounds • Manure storage with minimum risk on leaching • Appropriate application techniques • Buffer zones • Growing winter crops

  8. Results environmental indicators

  9. Results environmental indicators N leachingbaseline N runoffbaseline

  10. NO3 concentration in groundwater Difference baselinevs 0-compl. NO3 concentrationbaseline

  11. Results NH3 emission NH3 emissionbaseline Difference baseline vs 0-compl.

  12. Results N2O emission N2O emissionbaseline Difference baseline vs 0-compl.

  13. Effect of measures

  14. Final remarks • Cross compliance levels uncertain • Only small changes in agricultural activities due to cross compliance • Nitrate Directive improved environmental quality • In 2005 the compliance levels for the Nitrate Directive are high • Efforts to comply are low, thus the easy (except the Netherlands) • Balanced fertilization can significantly reduce N emissions (currently only applied in 3 countries)
