1 SYNERGIES BETWEEN MEASURES FOR ADAPTATION, EMISSIONS TO AIR AND WATER QUALITY IN AGRICULTURE Marianne Bechmann and Lillian Øygarden NIBIO Trondheim,

2 EVALUATION OF SYNERGIES AND CONFLICTS Environmental measures in agriculture Effects on water quality, emissions to air and climate adaptation Background for targeting of subsidies towards several objectives

3 ENVIRONMENTAL MEASURES IN AGRICULTURE Regional Env. Programme (RMP): 460 mill. kr. Special env. measures in agriculture (SMIL): 220 mill. kr. Production grants Photo: Landbruksdirektoratet

4 EVALUATED TARGETS Water quality: particles, nutrients and pesticides Biology in water: effects on fish, insects and algea Emissions to air: Ammonia, methane, nitrous oxide Carbon storage in soil Climate adaptation Sustainability: soil threats, resource utilisation Ecosystem services: food production, recreation Land use and land management Emissions from animal husbandry were not evaluated

12 SYNERGIES OF CHANGED TILLAGE

13 SYNERGIES OF CHANGED SOIL TILLAGE Water quality: ++/+++ Reduced conc. of soil particles, phosphorus and nitrogen -/-- Increased use of pesticides increased concentrations of pesticides in water Biology in water: +/++ Improved conditions for biology Emissions to air: 0 No effect on ammonia and methane emissions + Positive effect on nitrous gas emission 0/+ Carbon storage in soil: Variable effect ++ Climate adaptation: Positive effect + Sustainability: Less loss of soil and phosphorus Other ecosystem services: Lower food production, improved recreation

23 SYNERGIES: All measures mentioned have a positive effect on losses of soil and phophorus The positive effect on soil and phosphorus losses have a positive effect on biology in water The emissions of nitrous oxides are reduced by most of these measures Carbon storage is affected positively or not affected Several measures are needed for climate adaptation Sustainability: Phosphorus resources Soil resources Recreational values and landscape

24 CONFLICTS: Some measures cause risk of increased use of pesticides and hence pesticide concentrations in water Tile drainage may under certain circumstances cause increased nitrogen losses to water Several measures cause reduced food production

25 CONCLUSION There are more synergies than conflicts Cost-effectiveness of measures should include more than one target Variation due to climate, soil and agricultural production system need to be reflected Synergies may be a criteria for prioritising subsidies in future environmental programmes
