Veehouderij (RAV) 61Appendix 4a The extra costs that farmers who are located near nature areas have to make when expanding are strongly related to the rules that apply. In Denmark, the rules for farms located within 400 m of Natura 2000 areas are stricter than in the Netherlands, and as a result the extra costs when expanding the farm are also higher. In both countries the extra costs are housing costs due the situation that farmers close to nature areas had to build stables which reduce the ammonia emission further than farmers who have no influence on nitrogen deposition on nature. For the finisher case farm with more than one neighbour, the extra costs in Denmark are about €32,000 per farm and in the Netherlands when no room for development is available €20,500 (Table S.1).When a farm is located between a distance of 400 and 2,000 m from a Natura 2000 area, the rules in the Netherlands are stricter and the extra costs are higher (Table S.1). So if the finisher case farm is located 2,000 m from a Natura 2000 area and the extra deposition is more than 0.014 kg of nitrogen per ha per year at the Natura 2000 area, then there are no extra costs in Denmark, whereas in the Netherlands the extra costs are €20,500 when no room for development is available. For dairy and broiler farms, the situation between both countries is quite similar.
S.2 Complementary findingsThe ammonia-emission regulations around nature areas are very different in Denmark and the Netherlands. In the Netherlands, the rules apply to extra emission, and it is always possible to emit the same amount of ammonia as before expanding. In Denmark, the rules are stricter in case of expansion in that a farm that is located close to a Natura 2000 area (<400 m) must have a lower emission than before expanding (this applies to the whole farm).
| Wageningen Economic Research Report 2018-009When a farm is located at 2,000 m from Natura 2000 areas, a farm in Denmark has to take no extra measures when expanding. In the Netherlands, the type of measures a farm has to take does not necessarily depend on the distance from a Natura 2000 area. It all boils down to whether the expanding farm will cause too much extra nitrogen deposition in nitrogen-sensitive nature areas.When the extra deposition is more than 1 mol or 0.014 kg of nitrogen deposition per ha, t...
