Abstract
The European Common Agricultural Policy is shifting an increasing part of the subsidies to eco-conditionality. Henceforth, it becomes essential to evaluate the environmental effect of agricultural practices, and more generally performances of cropping and farming systems, in order to design and to develop more sustainable systems. This assessment is being implemented for the main cropping systems of some French regions, using environmental indicators. Eleven exposure indicators were chosen in order to represent a wide range of specific sustainability objectives dealing with water, soil, air, non-renewable resources, biodiversity, and landscape. The results present the sustainability assessment for the crop rotations of Champagne Berrichonne region in the Centre of France.

We described the succession of crops, the management of each crop from the preceding crop to its harvest, as well as the production results obtained
To sum up this study, 11 indicators were used. Is this number enough to deal with the main aspects of durable development ? Is it necessary considering the priority items for the concerned agricultural region ? These were inevitable questions
Summary
To evaluate the performance of durable development, the OECD proposed to study a whole set of impacts. We started from this multi-criteria approach and stressed out the different sets of possible impacts [3]:. We did not take into account the expensive indicators of environmental states, which are not sufficiently sensitive to modifications of practices in an isolated plot, as well as other producers' indicators which are less meaningful for the Society and offer no scientific validity to estimate the environmental impacts [5]. Considering the presently available methods [6, 7], the working group proposed eleven indicators gathered in four different fields of main impacts: the use of energy and water resources, the quality of water, soils and air, biodiversity and landscapes
