  1. N-surpluses and handling of the Water Framework Directive in Sweden Hans Nilsson Swedish Board of Agriculture

  2. Average N-surplus from nutrient balances in Greppa Näringen, 2000-2004

  3. N-surplus in plant production- Correlation to area

  4. N-surplus in plant production- Correlation to soil texture (% sand)

  5. N-surplus on farms milk production900 farms without manure import/export

  6. N-surplus on farms milk production- slurry vs farmyard manure (FYM)

  7. N-surplus on farms with pig production

  8. Calculations at SLU have shown that • N-leaching from arable land decreased by 7000 tonnes or 12% in the period 1995-2003 • Average N-leaching decreased from 21.8 to 20.0 kg N/ha arable land • The goal is 7500 tonnes by 2010 • The goal is 93% fulfilled already Source: Beräkning av förändringar av kväveutlakning från åkermark mellan 1995 och 2003PM from SJV, Magnus Bång, 2005

  9. Reasons for decreased N-leaching a Decreased arable land area b Increased nitrogen use efficiency c Use of catch crops and decreased autumn tillage d Increased proportion of manure spread in spring e Changes in crop rotation

  10. Decreased N-leaching in different regions West East North

  11. Investigation by SCB(Statistiska Centralbyrån) • Nitrogen balance for arable land • N-surplus 2003 = 46 kg N/ha (decrease of 4% from 2001) • Input 123 kg N/ha • Output 77 kg N/ha • Nitrogen balance including animal production • Total N-surplus 2003 = 168 ktonnes or 54 kg N/ha(decrease of 8% from 2001) Source: Kväve- och fosforbalanser för jordbruksmark och jordbrukssektor 2003, Rapport MI40SM0501 , SCB 2005, Link

  12. The Water Framework Directive (WFD) • Legislation for protection of all water bodies in Europe • Lakes, Rivers, Coastal Waters, Groundwater (drinking water) • Sweden has over 85,000 lakes >1 ha and over 60,000 rivers. Lakes >50 ha and rivers >1000 ha are going to characterize water protection areas • Good water status before 2015, but exceptions can be accepted for Heavily Modified Bodies. • Based on the state of reference, intercalibrated between the countries in EU • The water shall have a price and the polluter has to pay? PPP (Polluter Pays Principle).

  15. Questions • What is good water status? • What does Heavily Modified Bodies mean in different countries ? • How is PPP going to work?

  16. Good water status

  17. Intercalibration • All member states have identified water bodies with high and good ecological status • In 2006 the EU Commission will inter- calibrate the sites, which means the same objectives will apply for the same types of water bodies in all member states

  18. Little deviation from unaffected conditions Observed value EQR= Reference value Present and future (WFD) environmental objectives EQR=1 No or very little deviation from unaffected conditions High status Intercalibration 2006 Good status Moderate status Moderate deviation from unaffected conditions Unsatisfactory status Bad status EQR=0

  19. Biology Aquatic flora (macrophytes) Bottom fauna Fish Quality factors for classification of ecological status Phys/chem • Water temp • Oxygenation • Salinity • pH, alk, ANC • Nitrogen, Phosphorus • Toxic substances Hydromorp • Hydrological condition • Continuity • Morphological condition One out, all out principle

  21. Identified sensitive areas in EU:s Nitrate Directive

  22. Sensitive areas in Swedenaccording to the Nitrate Directive Problem in the Baltic sea? Phosphorus + Nitrogen Problem on the West coast? Nitrogen + Phosphorus

  23. Exceptions according toHeavy Modified Water Bodies

  24. Proportion of the flowing water that is characterized as Heavy Modified Water BodiesUnpublished material approx. • Belgian, average: 41% • Denmark, ? • Finland: 25% (km) • France: 26% • Ireland: 39% • Netherlands, average: 57% • Norway: 14% • Great Britain, average: 36% • Sweden: 8% • Germany: 37% Source: Anna Mcarthur, Federation of Swedish Farmers, unpublished

  25. Criteria in Sweden • Lakes with more than 3 m regulation depth • Lakes that were significantly lowered 1960 or later • Large dams for electricity production • Largest harbours

  26. Who has to pay and how is the price going to be established? PPP in WFD

  27. Some thoughts from LRF* in Sweden on how to divide PPP between the producer and the consumer- Example : Potatoes 1. Catch crop 2. Irrigation 3. Optimized fertilization 4. Minimized tillage Residual leakage * Federation of Swedish Farmers

  28. Some thoughts from LRF* in Sweden how to divide PPP between the producer and the consumer Example : Potatoes This leakage depends on HOW the farmer grows his potatoes This leakage is due to THAT potatoes is grown and is only affected by consumption. * Federation of Swedish Farmers

  29. Some thoughts from LRF* in Sweden how to divide PPP between the producer and the consumer Example : Potatoes Who is going to pay for the HOW-part? Who is going to pay for the THAT-part? * Federation of Swedish Farmers
