Biodiversity, the diversity of life at all scales, is a characteristic feature of our planet and a precondition for human life. However, only during the last two decades biodiversity has become an important research topic. Scientific projects deal with the measurement of biodiversity, the factors that affect biodiversity and with effects biodiversity itself has on ecosystems and other variables. The topography of Switzerland is very complex and the ecological conditions vary over small scales. This probably explains the large local biodiversity. Since human population pressure and economic activity are also particularly high in Switzerland, our country has a special responsibility to develop a comprehensive strategy for the conservation and sustainable use of biodiversity. At the same time, it could play a major role in global biodiversity policy.
In wheat crops, pesticides can be used more sparingly without sacrificing cost-efficiency. With oilseed rape the situation is more difficult, since the reduced yields are not offset by higher revenues. These are the findings of the analysis of the first two harvest years of the PestiRed project.
Soil samples can be measured directly in the field by means of spectroscopy. Agroscope researchers have tested mobile devices and shown how to make the best use of them.
Three widely used and newly revised approaches that optimally complement each other are available to practitioners, trainers and educators. Videos and apps have been designed to facilitate their use.
