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 water scarcity. One is physical. The other is economic water scarcity. [2]: 560 Physical water scarcity is where there is not enough water to meet all demands.
Water stress is one parameter to measure water scarcity. It is useful in the context of Sustainable Development Goal 6. [16] Half a billion people live in areas with severe water scarcity throughout the year, [11] [14] and around four billion people face severe water scarcity at least one month per year.
People in urban areas (2.4 billion) will face water scarcity by 2050. [225] Water scarcity has been described as endemic, due to overconsumption and pollution. [227] The report states that 10% of the world's population lives in countries with high or critical water stress.

Water resource policy varies by region and is dependent on water availability or scarcity, the condition of aquatic systems, and regional needs for water. [18] Since water basins do not align with national borders, water resource policy is also determined by international agreements, also known as hydropolitics. [ 19 ]
Water scarcity: Water demand exceeds supply in many regions of the world. This can be due to population growth, higher living standards, general economic expansion and/or greater quantities of water used in agriculture for irrigation. Increasing water pollution and low levels of wastewater treatment, which is making local water unusable.
