The global population never stops increasing year by year in the recent several decades. Well as the population increases, we need more and more fresh water every day and this demand will escalate alarmingly. However, not everyone knows that the fresh water on earth is only 2.5 percent of all water sources. And less 1% of all the water is available to us. This is because 70% of the fresh water on earth is frozen in the icecaps of Antarctica and Greenland and 30% is mostly found underground.
Demand vs supply
In the future, we will meet many problems, like a large population, a changing climate and extensive urbanization. These problems will increase the demand for fresh water. It is estimated that the demand for fresh water will increase by 30% in 2030. On the other hand, our fresh water resources on earth are limited and only Accounts for a very small proportion.
Besides the increasing domestic demand for fresh water, the development of agriculture and industry also depends on much more fresh water supplies. Domestic water use only accounts for 10% of global water consumption, while agriculture and industry account of 90%. – 70% and 20% respectively. This also means industry and agriculture cannot develop without fresh water.
The leakage of water is also a big issue for the increasing cities in density and urbanization expands. For example, in London, about 1,000 million liters of water is wasted because of pipe leakage. This also means about 40% of the city’s fresh water supply is wasted. In Italy, leakage problems are more serious. Up to 70% of water pumped is wasted due to the poor city pipes.
Access to clean, safe water
Today, about 800 million people don’t have access to clean, safe fresh water to drink. And as the climate changes dramatically, this issue will become more serious. Therefore, water challenges become a global issue that every country should have to face.
How to Reduce Our Water Footprint?

In our daily lives, there are something we can do to really help to reduce our water footprint. And you can learn more ways on the following infographic about water challenges in the 21st century.
