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.
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]

Water is a basic need of life and presently, an estimated one billion persons do not have access to safe drinking water, and even more have inadequate sanitation. [5] Global institutions, including the United Nations, warn of the impact of a growing global population and the effects of climate change on the ability of people to access freshwater. [3]
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]
The other is economic water scarcity. These terms were first defined in a 2007 study led by the International Water Management Institute. This examined the use of water in agriculture over the previous 50 years. It aimed to find out if the world had sufficient water resources to produce food for the growing population in the future.
