Global map of countries by total renewable internal freshwater resources (billion cubic meters) in 2020, according to World Bank [1]. This is the list of countries by total renewable water resources for the year 2020, based on the latest data available in January 2024, by World Bank and Food and Agriculture Organization (AQUASTAT data). [2]
Global map of countries by total annual freshwater withdrawals (billion cubic meters) in 2020, according to World Bank [1] Spatial variability of water yield along the delineated near-offshore region of 200 km across the world [2] This is the list of countries by freshwater withdrawal for the year 2020, based on the latest data available in ...
Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
Map of global water stress (a symptom of water scarcity) in 2019. Water stress is the ratio of water use relative to water availability and is therefore a demand-driven scarcity. [1] Water scarcity (closely related to water stress or water crisis) is the lack of fresh water resources to meet the standard water demand. There are two types of ...
In 1960, the Aral Sea was the world's twelfth-largest known lake by volume, at 1,100 km 3 (260 cu mi). However, by 2007 it had shrunk to 10% of its original volume and was divided into three lakes, none of which are large enough to appear on this list. [17]
It is said that this vast underground reservoir could supply fresh drinking water to the world for 200 years. However, at closer inspection, if the world population were to stay at an equilibrium of about 6.96 billion, not even taking into account that babies need less water than grown adults, this figure reaches 1600 years, allowing about 9 ...
Groundwater is fresh water located in the subsurface pore space of soil and rocks.It is also water that is flowing within aquifers below the water table.Sometimes it is useful to make a distinction between groundwater that is closely associated with surface water, and deep groundwater in an aquifer (called "fossil water" if it infiltrated into the ground millennia ago [8]).
