3. University of Natural Resources and Applied Life Sciences, Vienna Department of Sustainable Agricultural Systems I Division of Agricultural Engineering I Dr. Barbara Amon  Countries must annually report emissions.  Emission inventories must be transparent, consistent, comparable, complete and accurate.  It is therefore necessary to estimate emissions by applying models that link activity data to emission factors to calculate net emissions. Those models should offer the possibility of showing the effect of mitigation measures.  The knowledge on activity data is still insufficient in many countries. Background

4. University of Natural Resources and Applied Life Sciences, Vienna Department of Sustainable Agricultural Systems I Division of Agricultural Engineering I Dr. Barbara Amon  Survey farm management techniques and practices  Detailed overview of Austrian animal husbandry  Improvement of the Austrian emission inventory  Modelling of typical farms and estimation of their emissions  Development of emission scenarios  Proposal of feasible mitigation measures Aims of the research project

5. University of Natural Resources and Applied Life Sciences, Vienna Department of Sustainable Agricultural Systems I Division of Agricultural Engineering I Dr. Barbara Amon  Questionnaire assesses relevant parameters in all stages of animal husbandry systems: o housing and exercise yard o grazing o waste and washing water o manure storage o manure application o animal feeding o mineral fertiliser application.  Adaptation of the Swiss DYNAMO questionnaire to Austrian conditions. Farm survey and questionnaire

6. University of Natural Resources and Applied Life Sciences, Vienna Department of Sustainable Agricultural Systems I Division of Agricultural Engineering I Dr. Barbara Amon  A representative sample of 5,000 Austrian farms was selected with the help of Statistics Austria  The survey differentiates three Austrian regions o Eastern Austria o Southern Austria o Western Austria  Farms with animal husbandry play a greater role in the emission inventory than arable farms and are more often represented in the survey sample. Representative sample of Austrian farms
