In intensive animal husbandry areas
surface water N and P concentrations often remain
too high. The Water Framework Directive calls for
additional nutrient emission abatement measures.
Therefore, costs and benefits for possible agricultural
measures in Flanders were first analysed in
terms of soil balance surplus. Finally, abatement
measures for agriculture, households and industry
were set off against each other and ranked according
to their cost-efficiency by the Environmental
Costing Model. Increased dairy cattle efficiency,
winter cover crops and increased pig feed efficiency
turn out very cost efficient. Other agricultural
measures are less cost efficient than for instance
collective treatment for households and industry
