Biodiversity in agriculture

Data and models to support pesticide reduction

The research project aims to uncover the data treasure on agriculture and biodiversity already available but still unexploited in ministries, environmental agencies, advisory networks, colleges and universities in Baden-Württemberg with modern computer model systems for advisory and training purposes. For this purpose, the model system MPMAS_XN developed at the University of Hohenheim will be used to simulate individual and groups of (hundreds or thousands of) farm holdings economically and biophysically (yield formation). Mechanical weed control measures to reduce pesticide use will serve as a concrete case study. Possible effects on the cultivation plan, labor and machinery use and, above all, on the economic outcome are analyzed with the model system. In order to compare the simulation results with reality, interactive modeling sessions with farm managers and their advisors in the state-level biodiversity farming network will take place. The model system thus validated can then serve as a platform for discussion and training, as well as for policy analysis.
