To develop, for and in partnership with the Walloon Region authorities, agricultural monitoring tools applicable to production as well as to environmental protection (agri-environmental measures). Several applications were developed thanks to the combined expertise of the various teams, optimising at best the spatial information supplied by the three particularly pertinent infor- mation sources: - The Integrated Administration and Control System (IACS) that has been operational in a cartographic version since 1997 at the Directorate-General for Agriculture. This system pro- vides annualy updated information on the shape, location and land occupation of almost all agricultural parcels in the Walloon Region. - The yield forecasting tool (B-CGMS) developed on the basis of the European yield forecasting system that uses spatial agrimeteorological observations (meteorological, pedological, phe- nological data). This provides a series of biophysical variables that can be useful in monitoring the state of agriculture (biomass, grain yields, leaf area index, water stress, etc.). - Remote sensing. The agricultural parcel was chosen as the reference spatial unit for the development of the various applications. The project produced a series of indicators of direct use to the authorities for the purposes of control, support and overall monitoring, including: - The optimal localization of grassy headlands alongside crop parcels. - Yield forecasting. - Farm crop diversity (crop rotation). - Assessment of crop succession quality. - Area of arable land left fallow in winter. - Risk of erosion. - Monitoring of crop parcel size. - Water stress monitoring. - Monitoring of grassy headlands alongside crop parcels. - Monitoring of plant cover of agricultural plots in winter. - Monitoring of nitrogenous fertilization of maize. - Identification of elements of the agri-ecological network. - Optimal localization of extensive field borders on permanent pastures. - Monitoring of extensive field borders on permanent pastures. - Parcel distribution on farms. In 2006 the Walloon Region began the operational implementation of some of these indica- tors.

AGRICULTURE SAGRIWATEL The world of agriculture today Agriculture in Wallonia is evolving along the same lines as elsewhere in Europe. Beside production activities, the need to manage rural areas and maintain the quality of the environ- ment is giving rise to a whole string of new activities. At the administrative level, it is the re- gional authorities that have had full responsibility for these activities since 2002, acting as the interface between the farmers and the constantly updated European directives. This interface role extends beyond the complex organisation required to distribute farming subsidies and includes management of the various agri-environmental interests, such as the preservation of ecosystems, maintenance of landscape diversity, conservation of the local rural heritage and sustainable agriculture. Geomatics Geomatics is extremely useful for such large-scale planning. It serves as an aid in developing the tools needed for supervision, monitoring and decision-making. Drawing on the expertise of four research centres, the SAGRIWATEL project integrated remote sensing alongside other information systems with the aim of developing applications of practical use in the field. These applications give access to valuable information on the agri-environmental practices that farmers can adopt, such as the optimal location of field borders, the crop succession and rotation, possible use of vegetation cover in winter, or the correct quantities of nitrogenous fertilizer to be used in maize fields. In return, the compilation of these material data can also serve to usefully support the agricultural world in a broader frame.
