Application of a Crop-Farm-Indicators modelling chain to assess the impact of the EU nitrate directive in the Midi-Pyrenees region

摘要

The rapid evolution of economic and environmental constraints on farming systems require cropping systems design or assessment to be conducted in the context of market instability as well as economic (e.g. CAP in EU) and environmental policy changes.The Nitrate Directive (91/676/EC) is one of the oldest EU environmental policy, designed to reduce water pollution by nitrate from agricultural sources, through a set of measures, defined at regional level, and mandatory for farmers of vulnerable zones.
