For example, managing a given watershed may make more sense than managing the amount of global freshwater consumption to stay below an arbitrary, sustainable «limit» of 4,000 cubic kilometers per year.

Roughly 70 percent of worldwide water use goes to food production, which is implicated in groundwater depletion and ecologically destructive freshwater consumption from California to the Indo - Gangetic Plain to Central Asia to northern China.

The most straightforward — and likely the least controversial — method for improving water productivity that Grant and his co-authors suggest is expanding efforts at reducing freshwater consumption, such as replacing single - flush toilets with dual - flush toilets or installing high - efficiency shower heads and washing machines.

Lead author Dr Robert Holland, also from the University's Centre for Biological Sciences, said: «Based on mapping patterns of freshwater consumption associated with energy sectors at subnational scales, our analysis also reveals that pressure on freshwater resources associated with energy production happens in a number of freshwater scarce river basins globally.

Thanks to increased energy demand and the growing popularity of freshwater - recirculating plants, which consume the most water of any thermal plant, freshwater consumption from Indian thermal utilities grew by 43 percent from 2011 - 2016, from 1.5 to 2.1 billion cubic meters a year.

«Reducing power plants» freshwater consumption with new silica filter.»

The collaborative study of freshwater consumption associated with energy usage, led by the University of Southampton and published in Proceedings of the National Academy of Sciences, found that petroleum demand within a nation typically drives consumption of freshwater resources internationally, whereas gas and electricity demand drives freshwater consumption within the nation itself.

While freshwater consumption by the electric and gas sectors largely occurs within countries where the demand for energy originates (91 per cent and 81 per cent respectively), over half of freshwater consumption for the petroleum sector comes from international sources (56 per cent).

In the UK, 75 per cent of freshwater consumption for the petroleum sector is from international sources, with 43 per cent of gas and 87 per cent of electric freshwater consumption coming from domestic sources.
