The Institut Nationale Recherche Agromique (INRA) is the biggest insitute for agronomic research in Europe. Reactive nitrogen is an issue which is mostly related to agricultural by the way of crop fertiisation and livestock farming (especially manure management(. INRO could provide INMS with (i) databases on nitrogen use, nitrogen, carbon and water fluxes; (ii) crop models including carbon and nitrogen cycling, economic models, actor models; (iii) decision support tools for nitrogen ferilisation and estimating nitrogen losses; and (iv) long term observation sites. INRA has strong partnerships with many agricultural stakeholders and French decision makers. The invovlement will see to distill and sythesise key experiences from French agricultural allowing technology sharing with regional studies and analysis of barriers to change.
