Domestic use: By now, the water we use directly in our homes accounts for the smallest part of water use – yet it is essential for our survival: for drinking, preparing foods, and for washing ourselves. The consumption varies greatly – for example, from as little as 10 L per person an day in low-income areas in Ulan Bator (Mongolia) (World Bank 2010) to almost 600 L per person and day in the United States. A minimum of 50 L per day as a basic water need is recommended (FALKENMARK 2005; WATER ENCYCLOPAEDIA 2010).
Other uses: Furthermore, also other stakeholders such as fisheries, tourism, or transport use water resources.
