A huge portion of this freshwater is locked up in ice, with most of the remaining freshwater found below our feet as groundwater. Surface and other freshwater make up a very small fraction of total freshwater. See the Figure below. The top 5 countries in terms of annual renewable water resources include Brazil, Russia, Unites States, Canada and China (source). Brazil’s annual renewal water resources is 8,223 km3/year compared to Australia’s 336 km3/year. One-third of the world's population lives in water-stressed co
