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 ...
Contamination of groundwater decreases the replenishment of available freshwater so taking preventative measures by protecting groundwater resources from contamination is an important aspect of water conservation. [8] An additional strategy to water conservation is practicing sustainable methods of utilizing groundwater resources. [8]
Watershed management is the study of the relevant characteristics of a watershed aimed at the sustainable distribution of its resources and the process of creating and implementing plans, programs and projects to sustain and enhance watershed functions that affect the plant, animal, and human communities within the watershed boundary.

Water being a finite resource, but also the most abundant resource of the three sectors is the most exploited. Water is primarily used in forestry and fishery, agricultural production (in its entire agri-food supply chain) and is used to create and/or transfer energy in varying forms.
Water resource policy varies by region and is dependent on water availability or scarcity, the condition of aquatic systems, and regional needs for water. [5] Since water basins do not align with national borders, water resource policy is also determined by international agreements, also known as hydropolitics. [6]
Geographic information systems (GISs) have become a useful and important tool in the field of hydrology to study and manage Earth's water resources.Climate change and greater demands on water resources require a more knowledgeable disposition of arguably one of our most vital resources.
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.
