Cape Town has become the world's first largest city in south Africa, where there is a decrease in drinking water in modern times.

This is the problem that experts have been paying attention for a while.

Apparently, water is spread over 70 percent of the world, but only three percent of it is worth drinking which is proven to be inaccessible due to population growth, pollution and other reasons.

At least one billion people have a problem of water shortages in the world and 2.7 billion people are facing water scarcity at least one month of the year.

In 2014, five major cities of the world were surveyed in 2014, which showed that one of the four cities is 'water pressure'. According to the United Nations, it is the situation when the annual amount of water reduces 1700 cubic meter (17 lakh liters) per person.

According to the UN forecast, the demand for fresh water in the world of 2030 will increase by 40%, which is due to environmental change, population growth and change in human behavior.

In all cases, Cape Town is like a peak of iceberg, which only one part of the water is out of water and nine parts are inside.

Below the situation of six major cities of the world is being described, which is worried that they are in danger of water scarcity like Cape Town.

1: Banglore

2: Beijing

3: Qahira

4: Masco city

5: Istanbul
