Half the world faces water shortage by 2080

Half the world's population could face a shortage of clean water by 2080 because of climate change, experts warned Tuesday.

Wong Poh Poh, a professor at the National University of Singapore, told a regional conference that global warming was disrupting water flow patterns and increasing the severity of floods, droughts and storms — all of which reduce the availability of drinking water.

Wong said the U.N. Intergovernmental Panel on Climate Change found that as many as 2 billion people won't have sufficient access to clean water by 2050. That figure is expected to rise to 3.2 billion by 2080 — nearly tripling the number who now do without it.

Reduced access to clean water — which refers to water that can be used for drinking, bathing or cooking — forces many villagers in poor countries to walk miles to reach supplies. Others, including those living in urban shanties, suffer from diseases caused by drinking from unclean sources.

At the beginning of the decade, the World Health Organization estimated that 1.1 billion people did not have sufficient access to clean water.

Asia, home to more than 4 billion people, is the most vulnerable region, especially India and China, where booming populations have placed tremendous stress on water sources, said Wong, a member of the U.N. panel.

"In Asia, water distribution is uneven and large areas are under water stress. Climate change is going to exacerbate this scarcity," he told the two-day Asia Pacific Regional Water Conference attended by policy makers, government officials, academics, businessmen and consumer group representatives.

Scientists have said global climate change takes many forms, causing droughts in some areas while increasing flooding and the severity of cyclones in others. Droughts reduce water supply, and floods destroy the quality of water. Rising sea levels, for instance, increase the salt content at the mouths of many rivers, from which many Asians draw their drinking water.

"As human civilization develops, the environment is increasingly affected in negative ways. Floods, drought, changing rainfall patterns and rising temperatures are signs of our misdeeds to nature," said Rozali Ismail, head of a state water association in Malaysia.

    • Ok I understand and agree with you completely, I too feel that way.
      Science is not an exact recipe yet when you combine all known human understanding with logic you come to a conclusion one that may offer you more truth than fiction. So you think the last 200 years of man and Oil have caused climate change? You’re going to have to widen the page because history is a misconception and has glorified many events, yet this is our forced perspective it has been trusted under our noses since you and I were children. It may have been designed to keeps knowledge from those who seek it. To put it another way it lacks substance. There is another cause to climate change, Chernobyl, Nuclear power, every nuclear disaster, Hiroshima and Area 55 world’s largest nuclear bomb testing site. I am going to stop here. You are going to have to do the research and it is not what you would have expected.

    • Forty percent of the world is now in some form of drought, much of it severe and real people are suffering because of it. So excuse me while I actually focus on that. Believe what you will about climate change, the EFFECTS of it are for sure real as is the science behind it. Unfortunately, not too many seem to care about water. And I have read some about the sun, etc. and some other "theories" and as far as I am concerned they have no basis in fact to what is causing the droughts we are now seeing globally. People burningfossil fuels and wasting water are not caused by the Earth's rotation, they are caused by greed, ignorance, and selfishness.

    • You should work out my asumption on this one perspective. Its a hum dinger.

      Climate change is a natural phenomenon, not one I entirely like. I am basing my ground work on the Sun the moon and astrophysics. CFC’s and all of that good stuff are not the true cause of what you perceive to be happening. There is a shift in normal global position. The earth’s rotation, pitch and magnetic hemispheres could be about to move how much is the debate. However it is not a media topic of conversation because it will imply too many questions about what if’s and buts and something called the 26000 year wobble otherwise known as a precession. Yet don’t read up on rubbish being put out on the internet. However do look at moon precipitation.

    • Sorry, global warming (climate change) is not speculative, it is now fact. Though I do agree that population especially in developing countries is certainly a big part of this entire issue that is not addressed nearly enough.

    • And just to add: This then will also tie into renewable energy. Concentrated solar power, photovoltaic solar power, wind, etc do not use the intense amounts of water in processing that coal and nuclear use. it simply will not be feasible to use these energy sources in a world of drought.

    • JanforGore,

      Again you are right on. I think clean water is the one issue that everyone, regardless of politics, beliefs, etc, can rally around. From there we can build a sustainable future. We really do have to live the bumper sticker: think globally, act locally.

      To everyone who reads these posts: is the water in your area clean? If not, what can you do?

      Yes, clean water is a human right and leads to health, dignity and I believe ultimately peace. I would suggest that anyone who has a question bring it to their municipal authority and local govt.That is what they are there for and we are absolutely entitled to see water surveys they do that test water quality and to know where it is coming from.

      You're welcome. I've been talking about this for years now. Water is very spiritual to me, and I am outraged at what I see happening globally. What gives Nestle the right to go to a drought stricken area and pump the water left there to put it in plastic pollution making bottles to sell for a profit? Climate change/wasteful practices particularly re: agriculture are already effecting 40% of this planet.Where are we going with all this? There is only one blunt sentence to tie this all in: Without water we die.

      It is the one resource I know I would fight for.

    • And that half world will be looking for clean water sources from those areas that may remain that have water. This is a recipe for disaster. How can humans see the impending disaster before their eyes and continue to not do enough to reverse it? What stops us from doing the morally right thing? Even though we know there is enough water in this world to stave off the thirst that kills, we will continue to allow multi national corporations to steal it and sell it for exhorbitant prices that the poor of this world cannot afford. We will continue to spew GHG pollution into the atmosphere at a rate of 70 million tons a day thus exacerbating drought, glacier melt, and erratic weather patterns.

      We will continue to allow governments working in tandem with global organizations fix prices that are out of the realm of reality in order to exacerbate war and suffering because it keeps them profitable and in power. We will continue to allow mismanagement of funds on every level that could be used to fix and build infrastructure. We will continue to pollute and waste the very source of life we need to sustain us.

      Or will we? Will it have to get this bad before we reach our epiphany as a species? Will we then see how much a part we are in the solutions to this crisis? We all have hands. We all have feet. We all have voices. We all have consciences. We need to use them all now to prove the title of this article wrong. I fear if we do not we are setting up the human species for its own extinction.
