Main research question/goal
This research project involves the development of an up-to-date emission inventory for Flanders. The Flemish Environment Agency uses a mathematical model developed by Ghent University (Pollet, 1996) to report its ammonia emissions data to Europe. In 1996, the legislation changed significantly (Manure Decree, VLAREM II) and science has also made progress in the meanwhile. The model needs to be updated. In addition, a farm and location-specific approach is necessary to comply with the EU demands concerning IPPC exploitations.Research approach
First, the model for the period 1990-2000 is updated. The starting point is the NIS data from municipalities. The estimations of the ammonia losses are reviewed for the ‘stable’ and ‘external manure storage’ emission stages and for the use of chemical fertilizers. The second model also starts from the year 2000 with a user horizon of 2020. For this model, the database of the Flemish Land Agency (VLM) is used as a starting point. This provides detailed information on farm and location level which is further processed in the model EMAV2020.Relevance/Valorisation
The European NEC directive (2001/81/EC) imposes emission ceilings for some important air pollutants like ammonia on the EU member states. Furthermore, the member states are obliged to provide yearly emission reports on sector level and prognoses for 2010. In the near future, goals will also be agreed upon for 2020. Since 2010, the Flemish Environment Agency uses the EMAV2020 model, developed at ILVO, as its standard reporting and prognosis application.
