Gesunde Ernährung und Nachhaltigkeit – Grundlagen, Methodik und Erkenntnisse eines Forschungsprojektes in Rahmen des proVISION Programmes des BMWF

Impact of changes in diet on the availability of land, energy demand, and greenhouse gas emissions of agriculture

“…Other data, especially concerning the direct energy consumption of agriculture, were obtained from the literature [41][42][43][44][45][46] and from stakeholder interviews. For more details on this procedure and the data that were derived, read about the study of Zessner et al [47]. In GEMIS, a separate process exists for each agricultural product.…”

“…In this scenario, exports stay at the same level as in the baseline situation in absolute terms. Currently, about 26,000 t of meat and 361,700 t of milk are exported per year, with most of the meat exported being beef [47]. Once the main assumptions for the scenario definition have been settled, the different scenarios and sub-scenarios examined in this work can be described.…”

“…As the efficiency of agricultural production is assumed to be the same as in the baseline period, the same amount of resources is consumed in producing a given product conventionally as in the baseline situation. Agricultural production is not expanded to forest areas, and the amount of fallow land cannot increase beyond the level observed in the baseline period [47].…”

“…A distinction was made between ruminant animals and monogastric animals. This calculation yielded the area of arable land and grassland needed for animal feed production [47].…”

“…As already stated, in all the scenarios the impacts on the existing conventional agricultural system of changing nutritional habits among the population of Austria are examined. The scenarios have been developed on the assumption that only conventional farming methods are used [47].…”
