The INMS Modellers’ workshop took place on the campus of Wageningen University in the framework of Activities 1.5 and 2.1. The Purpose of the workshop was to:
- Take stock of status of the modelling work and coordinate/plan the work in second phase
- Prepare modelling contributions for the International Nitrogen Assessment (INA)
- Discuss how modelling results can be made useful for INMS demonstration areas
- Discuss how modelling can be adapted to make it more useful in terms of assessing N shares on impacts and use it for cost benefit-analysis (CBA)
The modelling Activities in INMS have been organised into two phases of 18 months each, with the first phase concentrating on developing methodologies and the model linkages. The meeting in Wageningen took place at the end of phase 1. With 21 participants and 15 presentations of progress, a very good overview was achieved, and the modelling will now enter its second phase.
Agreement was achieved in all major aspects; the need to inter-compare the major economic models that will take up emission scenarios according to the INMS protocols, the formation of model chains (based on or integrated into either of these economic models) to adequately reflect N pollution effects, and the collaboration with the demonstration areas. Specific offers that consider the need of these communities were also created and further discussed with demonstration area representatives at the Madrid workshop in November 2019. In addition, agreements were made on the co-ordinating lead authors and potential participants of the book chapters on modelling in part D of the International Nitrogen Assessment.
