 Regional Crop Modeling: How Future Climate May Impact Crop Yields in SwitzerlandJournal of Socio-Economics in Agriculture (Until 2015: Yearbook of Socioeconomics in Agriculture), 2011, vol. 4, issue 1, 269-291 Abstract: Crop yield levels and crop yield variability depend to a high extent on climate conditions. Due to climate change the local crop growth conditions in Switzerland are expected to change. This study addresses the question how weather, soil and management factors influenced mean wheat yield levels in twelve study regions in the Swiss Plateau during the period 1990 – 2008. In addition, we assess potential impacts of climate change on wheat yield levels and yield variability. Applying a multiple regression model based on historical yield, weather, soil and management data in the period 1990 – 2008 at a regional scale, we find clear relations between yield levels and weather as well as management and soil factors. We show that global warming is assumed to decrease wheat yield levels in all study regions between 4-10%. Nevertheless, negative impacts of climate change on wheat production can be minimized or even overcompensated if the CO2 fertilization effect and possible adaptation measures are taken into account.
