ISO 14 001 at the farm level: Analysis of five methods for evaluating the environmental impact of agricultural practices

Faced with societyʹs increasing expectations, the Common Agricultural Policy (CAP) review considers environmental management to be an ever more critical criterion in the allocation of farm subsidies. With the goal of evaluating the environmental friendliness of farm practices, Franceʹs agricultural research and extension services have built a range of agricultural/environmental diagnostic tools over recent years. jective of the present paper is to compare the five tools most frequently used in France: IDEA, DIAGE, DIALECTE, DIALOGUE and INDIGO. All the tools have the same purpose: evaluation of the impact of farm practices on the environment via indicators and monitoring of farm management practices. ested on a sample of large-scale farms in Picardie, the five tools sometimes produced completely different results: for a given farm, the most supposedly significant environmental impacts depend on the tool used. These results lead to differing environmental management plans and raise the question of the methods’ pertinence. lysis grid of diagnostic tools aimed at specifying their field of validity, limits and relevance was drawn up. sulting comparative analysis enables to define each toolʹs domain of validity and allows to suggest lines of thought for developing more relevant tools for (i) evaluating a farmʹs environmental performance and (ii) helping farmers to develop a plan for improving practices within the framework of an environmental management system.
