The shortage of fresh water has already begun in different parts of the world, and Cape Town is the recent one to hit by it. The capital of South Africa is being regarded as the first modern-day city to face the threat of entirely running out of drinking water.
But, the warnings of the scarcity have been given for almost two decades now. Even the United Nations World Water Development Report suggested that the demand for drinking water supply will go up by 40% as of 2030. Another survey indicated that more than one billion people have a lack of access to water whereas more than 2.7 billion people don't have sufficient water for at least a month every year.
These give us an idea of dangerous situation many other cities are about to face. So, let us take a look at them.
The financial capital of Brazil faced water crisis just like Cape Town in 2015. The city's main water reservoir has been under threat for a long time. The recent survey in January 2017 revealed that the city has only 15% of water reserved.
Beijing has not only been hit by degrading air quality, but also major water crisis. In 2014, there were only 145 cubic metres of fresh water per person and according to World Bank, if a city has less than 1000 cubic metres of water per person than there exists scarcity.
Water shortage has been a critical issue for the inhabitants of Mexico City since forever. The conditions are so bad that only one in five people gets a few hours in a week from a tap for gathering fresh water. It is also reported that the city loses 40% of their water because of problems in the supply network.
When I read about London's water crisis, I was shocked because I never expected it to be on the list of the cities facing this issue. But, due to less rainfall, it gets fresh water from rivers including the Thames. But, the Greater London Authority has warned that water supply problem will begin in the next five years.
Jakarta's main water supply comes from the ground, and the coastal city is facing threats from rising sea levels. Many people even use illegal water digging methods which is making them more helpless.
The capital of Egypt uses water from the River Nile, but due to increasing amounts of agricultural and residential waste, the water in the river is getting polluted. And, according to the United Nations, if the same thing continues, the city will face scarcity by 2025.
Tokyo's major water supply depends on rivers and lakes whose indirect source of water is rainfall, but like most of the cities, Tokyo has rainfall problems.
The water rate in Cape Town has been declining rapidly. The city will even have a 'Zero Day' on which taps will be switched off, and people will go to different selected points for collecting rationed water. This will take place on 11 May.
One of the major cities of India is also expected to run out of water in the coming years. According to the officials, the problem arose due to the pollution in 85% lakes of the city. Not even a single lake among those have the water for even bathing purpose.
The time has come when we as the people of Earth unite to stop wrong water usage. Be healthy and keep saving water!
