Water scarcity is one of the biggest issues that the world is facing today. Defined as a problem that occurs when the demand for water exceeds the available water supply, water scarcity is seen as a problem that will only get worse, especially since water use continues to increase at an unprecedented rate globally.According to 2019 figures from UN-Water, an interagency mechanism that coordinates the efforts of United Nations (UN) entities and international organizations working on water and sanitation issues, global water demand is expected to continue increasing by 1 percent annually until 2050.
