Whether it’s from drought or lack of access, more than a billion people around the world don’t have enough clean water

Acute drought conditions and dwindling natural water resources are focusing more attention on what continues to be a worldwide problem: a lack of access to fresh, potable water.

Water scarcity can be defined as a lack of sufficient water, or not having access to safe water supplies.

Water is a pressing need in many areas of the world. That scarcity is spreading as water is needed to grow and process food, create energy, and serve industry for a continually growing population. Climate change is a key contributing factor.

Clean water is an essential ingredient of a healthy human life, but 1.2 billion people lack access to water, according to recent estimates from the International Water Management Institute cited in The World’s Water: Volume 8, edited by Peter H. Gleick. By 2025, two-thirds of the world’s population may be facing water shortages, according to the World Wildlife Federation. Available freshwater supplies worldwide continue to dwindle. By 2030, water demand is forecast to increase by 40%, according to Even Kuross, a management consultant based in Oslo, writing in Fair Observer. The world population is expected to reach 9 billion, placing pressure on water supplies.
