Vienna is Austria’s Capital with 1,84 million inhabitants by 2016, located in the north-eastern of Austria and embedded in a larger functional urban area hosting around 3 million inhabitants (Vienna, 2018). Observing a net-migration of above 20 000 people per year, it is expected that Vienna will reach 2 million inhabitants latest 2025. The elevation range is between 150 and 542 m. Vienna’s areal extent is 414 km². The land use in Vienna is distributed to around 50% green space, 36% built-up space and 14% road space. The green space forms the green belt around the built-up area. It covers the forest areas of the hilly Wienerwald ranging from the West to the North and agricultural areas in the eastern and southern outskirts as well as nature protection areas along the Danube River. Inside Vienna various small to large parks and the 21 km long Danube Island (an artificial flood protection measure) support this greening strategy.

Food
In total, about one third of the vegetables consumed in Vienna are produced within the city, a very high value for a large city. Agriculture has a share of only 0.1% and therefore plays a minor role in the city’s economy (Vienna, 2017). However, the cultivation and production of wines within the city borders (in the 19th, 18th, 17th and 23rd district) have a high socio-cultural value.

Water
Vienna is fully supplied high quality water with daily 400 000 m³ fresh alpine spring water daily transported through a 330km long distance tranport network. The first spring water pipeline was opened in 1873, the second was built in 1910. A thrid one, built in 2006 is used in case of high demand if the spring water sources are not sufficient and if repair works along the spring water pipelines are reducing the daily spring water supply.
