Detailed explanation-1: -Four billion people-almost two thirds of the world’s population-experience severe water scarcity for at least one month each year. Over two billion people live in countries where water supply is inadequate. Half of the world’s population could be living in areas facing water scarcity by as early as 2025.
Detailed explanation-2: -As the global population increases, and resource-intensive economic development continues, many countries’ water resources and infrastructure are failing to meet accelerating demand. Climate change is making water scarcity worse. The impacts of a changing climate are making water more unpredictable.
Detailed explanation-3: -Focus Areas. The Middle East and North Africa (MENA)* is the most water-scarce region of the world. Home to 6.3 percent of the world’s population, the region contains only 1.4 percent of the world’s renewable fresh water. As population pressures in the region increase, the demand for water resources rises.
Detailed explanation-4: -Climate change. Natural calamities such as droughts and floods. Increased human consumption. Overuse and wastage of water. A global rise in freshwater demand. Overuse of aquifers and its consequent slow recharge.
