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

Page 9: N-surpluses and handling of the Water Framework Directive  in Sweden

Reasons for decreased N-leaching

a Decreased arable land areab Increased nitrogen use efficiencyc Use of catch crops and decreased autumn tillage d Increased proportion of manure spread in springe Changes in crop rotation

Decreased N-leaching in different regions

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)

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).

Page 13: N-surpluses and handling of the Water Framework Directive  in Sweden

Timetable

• 2003 Constuction of water administration boards in Sweden. 5 regions

• 2004 The first basis analysis, preliminary goals for the environment

• 2006 Publish and consult on timetable and work programmes for the

production of river management plans

• 2006 Intercalibration

• 2007 Publish and consult on significant water management issues for each

river basin district

• 2008 Publish and consult on drafts of the river basin management plans

• 2009 First water plan to be fulfilled

• 2012 Water plan operational

• 2015 Main environmental objectives to be fulfilled

• 2027 Last chance to meet the objectives after 2x6 year postponements

Questions

• What is good water status?• What does Heavily Modified Bodies

mean in different countries ?• How is PPP going to work?

Page 16: N-surpluses and handling of the Water Framework Directive  in Sweden

Good water status

Page 17: N-surpluses and handling of the Water Framework Directive  in Sweden

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

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

PPP in WFD

Who has to pay and how is the price going to be established?

Page 27: N-surpluses and handling of the Water Framework Directive  in Sweden

Some thoughts from LRF* in Sweden on how to divide PPP between the producer and the consumer

-

Residual leakage

1. Catch crop

2. Irrigation

3. Optimized fertilization

4. Minimized tillage

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.
