United States 1960 postal stamp advocating water conservation.

Water conservation makes it possible to avoid water scarcity. It covers all the policies, strategies and activities to reach these aims.
For example, access to water, sanitation and hygiene services is one part of water security. [37] Some organizations use the term water security more narrowly for water supply aspects only. Decision makers and water managers aim to reach water security goals that address multiple concerns.
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 ...
