Un système d'aide à la décision pour évaluer et réduire la pollution diffuse | A decision support system for evaluating and reducing agricultural non-point source pollution

Abrassart, J.
Pollution of surface water by nitrates has reached such an extent that the accepted levels for drinking water are often exceeded. The local decision makers need the means to assist them inimproving of the aeras affected by nitrate pollution so that they can make the appropriate decisions to restore water quality. We have shown that when it is linked to various regional data bases on the environment and standard Geographical Information System software is used to handle them, the Overall Balance method may be considered as an aid to decision-making in order to evaluate diffuse pollution and simulate agro-environmental measures. By using of this method it has already been possible to identify areas where, according to regional regulations, there is excess of slurry. It is used regionally to define watersheds where projects or demonstrations would be threatened. | La pollution par les nitrates atteint des niveaux dont la presse s'en fait l'écho régulièrement. Nous avons réalisé un outil d'aide à la décision en reliant un SIG et des données diverses du milieu agricole. Un modèle de bilan global a été réalisé et permet d'identifier les zones à problème (pollution nitrique des eaux de surface). Une première application a vu le jour pour déterminer du point de vue réglementaire les zones à excédents structurels de déjection. Des programmes régionaux pour restaurer la qualité des eaux se sont servis de ces outils pour avoir une première approche de problèmes et définir ainsi des bassins versants de démonstration ou expérimentaux de restauration de la qualité des eaux.
