Échange de l'information environnementale : le prochain challenge ?

International audienceACTA Informatique is developing a two years project (2009-2010) on environmental information that is strongly related to the AgriXchange project, with a group of French organisations (including R&D institutes, AgroEDI Europe, and the association of French agricultural software programmes editors). We define environmental information as information about environmental factors impacting the agricultural production at farm level (e.g. weather data) and information describing the impact of agricultural activities on the environment (nitrogen leaks, chemical residues, manure, etc.). We tried to develop an inventory of environmental information as above defined. At first, we analysed relevant regulatory documentation. But we found that the analysis of data that are necessary to run decision support systems (e.g. for evaluating a risk at field or farm level), and evaluation tools (e.g. estimating the impact of cattle production on underground water quality) is more promising: we established lists of variables necessary to run many DSS and evaluation tools. We observed that these DSS and evaluation tools are not very much used. A reason for this situation seems to be the quantity of data to input. In this context, we investigated the interest of EDI links between farm management information systems (FMIS) used by farmers themselves and the above DSS and evaluation tools. Test beds were performed: the information exchanges between FMIS and DSS were proved quite efficient to make easier the use of DSS. We try to analyse the limits of this approach: - it makes necessary a strong co-operation between DSS producers and FMIS producers, - DSS producers have to use (at first!) information already input by farmers in their FMIS, - information exchange messages must be defined and normalised. In the example that we will present, we used two UN/CEFACT XML messages developed by AgroEDI Europe: the first one describes all operations performed at field level (eDAPLOS message) and the second one describes the phyto-sanitary situation of the field (Agronomical Observations Report Message). Our conclusion is that, providing a strong co-operation between DSS and FIS producers, the information exchanges dealing with environmental data could be very useful for farm management, and could increase very quickly. Exchanges of environmental information should thus become far more important than transmission of traceability information to co-operatives and industrial clients
