River Basins And Other Water Bodies

Abstract
The welfare economic consequences of reductions in nitrogen loading to the
aquatic environment in Denmark are analysed with the purpose of assessing the
cost-effectiveness of different abatement measures and instruments. The analyses
cover a broad range of instruments and measures. These include: nitrogen taxes
at sector level implemented as deposit refund systems, fertiliser accounts and
nitrogen quotas, requirements on utilisation of livestock manure, restrictions on
livestock density, set aside, forestation and wetland restoration. Based on the
analyses the conclusions are that deposit refund taxes at sector level are the most
cost effective instrument at national level, while other instruments and measures
have to be used to reduce nutrient emissions further in especially sensitive areas.
These areas are not identified yet, and the cost of action will depend on the
localisation. However, voluntary wetland restoration seems to be the most
cost-effective because the effects on nitrogen loading are superior to forestation
and set aside.
Keywords: nitrogen loading, cost-effective measures, general and local
management.
1 Introduction
Nutrient enrichment and eutrophication of river systems and other water bodies
are unwarranted effects of the agricultural production in Denmark. Despite a
large political awareness of the negative exposures and impacts from nutrient
loads to the water bodies since the 1980’ies, this is still an important
environmental problem in Denmark (cf. Andersen et al. [1]). The Danish Action
Plans for the Aquatic Environment I and II from 1987 and 1998, respectively,

nitrogen loading, cost-effective measures, general and local
management.
