Experiments for improving model based recommendation for adaptation of agriculture to regional climate changes: feed back effects of future atmospheric CO2 concentrations on water balance in agroecosystems
Description:
According to the climate prediction of the IPCC the atmospheric CO2 concentration and the severity of summer drought will increase over the next decades. In the context of the BMBF-research project LANDCARE2020 the Institute of Biodiversity of the vTI will conduct a biennial field experiment for studying the effect of CO2 and water supply on maize. Special attention is paid to the effects of the treatments on water balance of the agroecosystems. The main objective is to investigate whether CO2 and water supply affect maize growth only by influencing transpiration and water use efficiency or whether there are other mechanisms involved. The experimental data will be provided to modellers for improving crop models and agroecosystems models, which will be integrated in a decision support system (DSS) assisting farmers and other agricultural services in adaptation strategies to regional climate changes.
