Several million tons of matters are spread on the agricultural soils each year in France. Spreading is a usual way of recycling but it requires a meticulous monitoring in order to avoid all types of pollution. Likewise, an excessive and irrational spreading would be harmful for the natural environment. Presently, no national computerized system for spreading monitoring has been developed in France. The processing and the study of spreading project proposals is manually carried out i.e. without information system. However, a computerized tool will be really useful for the matter spreading data capture, the investigation, the data centralization and the crosschecking analysis. Thus, in the framework of a multi-actor project, Cemagref research institute is the contracting authority of the design step related to a French GIS-based information system called Sigemo. This e-government system is dedicated to the data centralization as well as the monitoring of the spreading operations through Internet. A main goal of the system is to improve the capability of producing easily analysis and indicators. After presenting the environmental stakes of spreading, this technical paper describes what Sigemo will be and emphasizes on the expected impacts of such a tool from an environmental and an organizational point of view.
