Water scarcity can mean scarcity in availability due to physical shortage, or scarcity in access due to the failure of institutions to ensure a regular supply or due to a lack of adequate infrastructure. Water scarcity already affects every continent. Water use has been growing globally at more than twice the rate of population increase in the last century, and an increasing number of regions are reaching the limit at which water services can be sustainably delivered, especially in arid regions.

The city where you live may be the next to run out of water. Regions of the world are increasingly vulnerable to a severe water crisis scenario. Factors such as population growth and increased demands, pollution, governance problems, losses and waste, climate change, and decline in the volume of rainfall are among the main contributions to raising the risk of water in cities.

Water on the earth is constantly on the move from one location and physical state to another, it evolves and recycles over and over again. This movement is called the water cycle. Heat from the Sun and wind cause water to evaporate from oceans, lakes and streams. Evaporation occurs when liquid water on Earth’s surface turns into water vapor in our atmosphere. Warm water vapor rises up through Earth’s atmosphere. As the water vapor rises higher and higher, the cool air of the atmosphere causes the water vapor to turn back into liquid water, creating clouds. When a cloud becomes full of liquid water, it falls from the sky as rain or snow—also known as precipitation. Rain and snow then fill lakes and streams, and the process starts all over again.

The Earth is a watery place. But just how much water exists on, in, and above our planet? About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog. Water is never sitting still. Thanks to the water cycle, our planet's water supply is constantly moving from one place to another and from one form to another.

The Ministry of Environment and Tourism of Mongolia, based on the law of protecting the environment, government agenda from 2016 to 2020 and national agenda “Sustainable development education”, initiated and has been implementing a series of campaigns under the name “Let’s change our attitude” to increase youth’s participation in conservation of nature. Upon the initiative, the “Green Passport” campaign has been organized among the eco clubs of all secondary schools since 2018 in cooperation with the Freshwater Resources and Nature Conservation Center, an environmental conservation organization under the MET.

Water covers about 71% of the surface of our mother earth. However, only 2.5% of all water on the planet is freshwater, of which only about 31 percent is accessible for human uses due to geographical and seasonal variations and the rest is trapped in glaciers and snowfields.

To create one pint of beer it takes 303 litres of water 95 percent of cucumber's weight is water 70 percent of the human brain is water. The average human body is made of up to 65 percent water. Newborn babies have even more, ringing in at 78 percent water.

The Watergen, an Israeli company developed a groundbreaking technology that can create fresh drinking-quality water from nothing but plain air and introduced series of water-from-air generators to the market.
