Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. These resources can be either freshwater from natural sources, or water produced artificially from other sources, such as from reclaimed water or desalinated water (). 97% of the water on Earth is salt water and only three percent is fresh ...
Natural resource management is a discipline in the management of natural resources such as land, water, soil, plants, and animals—with a particular focus on how management affects quality of life for present and future generations. Hence, sustainable development is followed according to the judicious use of resources to supply present and ...
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).

Water resources are natural resources of water that are potentially useful for humans, [104] for example as a source of drinking water supply or irrigation water. Water occurs as both "stocks" and "flows". Water can be stored as lakes, water vapor, groundwater or aquifers, and ice and snow.
Fresh water is a renewable and variable, but finite natural resource. Fresh water is replenished through the process of the natural water cycle, in which water from seas, lakes, forests, land, rivers and reservoirs evaporates, forms clouds, and returns inland as precipitation. [4]
Water resource treaties encompass many types of water like surface water, groundwater, watercourses, and dams. [19] [20] When a water resource can be shared equally, like a river acting as a border between nations, there tends to be less conflict than upstream/downstream water resource sharing agreements. [21]
Water conservation makes it possible to avoid water scarcity. It covers all the policies, strategies and activities to reach these aims. Population, household size and growth and affluence all affect how much water is used. Climate change and other factors have increased pressure on natural water resources.
Natural resources are resources that exist without actions of humankind; this includes characteristics such as magnetic, gravitational, and electrical properties and forces. Resources may be classified as renewable or nonrenewable .
