How do agricultural production systems differ in view of climate change mitigation? As in general multiple greenhouse gases are simultaneously released, which all need to be considered, narrow-focused studies can be delusive. In contrast, the whole production chain needs to be assessed and optimized for effective and real climate change mitigation. Furthermore indirect effects need to be considered triggered by differences in the use of production supplies, e.g. the purchase of mineral fertilizer or the consumption of fossil energy.
We integrate the results of our own and of external studies to systemic assessments of climate relevance. We include synergies and trade-offs on the production process, yields and other environmental targets such as water and soil protection.
Our research acitivities focus on
We focus on open questions regarding the valuation of contrary effects of greenhouse gas mitigation measures on emissions. Will the rewetting of peatlands cause significant methane emissions? Will measures aimed at reducing NH3 emissions or at carbon sequestration in agricultural soils trigger increased N2O emissions?
