Abstract

Experimental research and modelling of atmospheric-biospheric exchange processes of matter as well as related consequences for the energy balance of the atmosphere and for terrestrial ecosystems are current topics of climateimpact research. Agriculture is an important source and sink for a varietyof trace or "greenhouse" gases. The present contribution summarizes current results and open questions with regard to causes and consequences of changes in physical and chemical climate elements related to agriculture. This includes comments on the uncertainties of those data which form the basis for the prediction of changes of the physical climate, on the role of aerosols and on the contribution of agriculture to a potential "negative" climateeffect. It is concluded that in order to develop cause-effect relationships e.g. as a basis for abatement strategies additional experimental investigations of processes of the exchange of trace gases between the atmosphere and the biosphere and the development of adequate models to describe these processes are needed. Particularly, agricultural emission inventories for trace constituents with an adequate resolution in space and time and models describing the sink properties of whole landscapes are required. Agricultural climate research at the ecosystem level is likely to contribute to answering these questions.
