The objective of STIMUL Project is to assess the impacts of a reduction of 50% of mineral nitrogen fertilizers use in European agriculture.

Contributions:

• Mobilizing a set of economic, crop, and biodiversity models allowing us to cover the local and the global scale of the impacts of halving N use in Europe. These models differ in their methodologies, the scale of interest and resolution, but they are very complementary and are all relevant for a comprehensive analysis of the impacts of halving mineral nitrogen in Europe in terms of land use change and leakage.

• Accounting for different impacts: agronomic (yields), land use changes, economic (profit, welfare), carbon and biodiversity
