An application of an agro-economic model to environmental issues in the EC: A case study
应用IIASA的基本关联系统（BLS）构建欧共体农业营养平衡，结合模型情景分析，发现BLS适合中长期政策分析，且环保措施不一定与农业收入目标冲突。
This paper provides an application of IIASA's Basic Linked System (BLS) to environmental issues in EC agriculture. In order to find out whether such an integrative exercise can be done without exceeding the limits of the model, a nutrient balance of EC agriculture was constructed, which reflects the differences between nutrient extraction and delivery of nutrients to the soil; this balance was then run together with selected model scenarios. One of the conclusions is that the BLS can indeed be considered a suitable instrument for policy analysis, because it provides insights into the possible economic and environmental consequences of certain EC policies for the medium to long term. A second important conclusion drawn is that policy measures to protect and improve the environment do not need to be at variance with agricultural income objectives. The resulrs provide a basis for further research, which may become possible with a more detailed EC model of the same type, developed at the Centre for World Food Studies, which specifies the EC countries separately and distinguishes a larger number of agricultural commodities.
