Q. What does "Water Security" mean?
A. Water security can be defined as the ability to access sufficient quantities of clean water to maintain adequate standards of food and goods production, proper sanitation, and sustainable health care.
Q. But, we live on a water-rich planet; why are we concerned about water security?
A. Water, in absolute terms, is not in short supply planet-wide. But, according to the United Nations water organization, UN-Water, the total usable freshwater supply for ecosystems and humans is only about 200,000 km3 of water – less than one percent (<1%) of all freshwater resources.
The total usable freshwater supply for ecosystems and humans is less than 1 percent of all freshwater resources.
And, water use has been growing at more than twice the rate of the population increase in the last century. Specifically, water withdrawals are predicted to increase by 50 percent by 2025 in developing countries, and 18 per cent in developed countries. By 2025, 800 million people will be living in countries or regions with absolute water scarcity, and two-thirds of the world population could be under stress conditions.*
