This paper analyses the Austrian water footprint of consumption (WF(cons)) for different diets: the current diet, a healthy diet (based upon the dietary recommendations issued by the German nutrition society, or DGE), a vegetarian diet and a combined diet between both latter diets. As in many western countries, the current Austrian diet consists of too many products from the groups sugar, crop oils, meat, animal fats, milk, milk products and eggs and not enough products from the groups cereals, rice, potatoes, vegetables and fruit. Especially the consumption of animal products accounts for high WF amounts. These diets result in a substantial reduction (range 922-1,362 l per capita per day (lcd)) of the WF(cons) for agricultural products, which is currently 3,655 lcd. However, the Austrian water footprint of agricultural production (WF(prod) = 2,066 lcd) still remains lower than even the WF(cons) for a vegetarian diet (2,293 lcd). As a result the country is a net virtual water importer regarding agricultural products for all analysed scenarios.
本文分析了奥地利不同饮食的消费（WF（cons））的水足迹：当前饮食、健康饮食（基于德国营养学会的饮食建议，或 DGE）、素食和这两种饮食的组合。与许多西方国家一样，奥地利当前的饮食中含有过多来自糖、农作物油、肉类、动物脂肪、牛奶、奶制品和鸡蛋的产品，而来自谷物、大米、土豆、蔬菜和水果的产品却不足。特别是动物产品的消费占很高的 WF 量。这些饮食导致农产品消费的 WF（cons）大幅减少（范围为每人每天 922-1362 升（lcd）），而目前的 WF（cons）为 3655lcd。然而，奥地利的农业生产水足迹（WF（prod）=2066lcd）仍然低于素食饮食的 WF（cons）（2293lcd）。因此，对于所有分析的情景，该国在农产品方面都是净虚拟水进口国。
