Detailed explanation-1: -Water scarcity is a relative concept. The amount of water that can be physically accessed varies as supply and demand changes. Water scarcity intensifies as demand increases and/or as water supply is affected by decreasing quantity or quality.
Detailed explanation-2: -Water scarcity refers to the situation where potable, unpolluted water is lower than the demand in a region.
Detailed explanation-3: -Rainwater harvesting and recycled wastewater also allow to reduce scarcity and ease pressures on groundwater and other natural water bodies. Groundwater recharge, that allows water moving from surface water to groundwater, is a well-known process to prevent water scarcity.
