Water efficiency is the practice of reducing water consumption by measuring the amount of water required for a particular purpose and is proportionate to the amount of essential water used. [ 1 ] [ 2 ] Water efficiency differs from water conservation in that it focuses on reducing waste, not restricting use. [ 3 ]
The total volume of water on Earth is estimated at 1.386 billion km 3 (333 million cubic miles), with 97.5% being salt water and 2.5% being freshwater. Of the freshwater, only 0.3% is in liquid form on the surface. [ 2][ 3][ 4] Because the oceans that cover roughly 70.8% of the area of Earth reflect blue light, Earth appears blue from space ...

The Cape Town water crisis in South Africa was a multi-year period in 2015–2020 of water shortage in the Western Cape region, most notably affecting the City of Cape Town. Dam water levels began decreasing in 2015 and the Cape Town water crisis peaked during mid-2017 to mid-2018 when water levels hovered between 14 and 29 percent of total dam ...
Groundwater is an important water resource for the supply of drinking water, especially in arid countries. The Arab region is one of the most water-scarce in the world and groundwater is the most relied-upon water source in at least 11 of the 22 Arab states. Over-extraction of groundwater in many parts of the region has led to groundwater table ...
With rising demand, the quality and supply of water have diminished. [7] Water use has been increasing worldwide by about 1% per year since the 1980s. Global water demand is expected to continue increasing at a similar rate until 2050, accounting for an increase of 20–30% above 2019 usage levels. [6]
