Water demand will ‘outstrip supply by 40% within 20 years’ due to climate change and population growth

From the article:

Water demand in many countries will exceed supply by 40 per cent within 20 years due to the combined threat of climate change and population growth, scientists have warned.

A new way of thinking about water is needed as looming shortages threaten communities, agriculture and industry, experts said.

In the next two decades, a third of humanity will have only half the water required to meet basic needs, said researchers.

Agriculture, which soaks up 71 per cent of water supplies, is also likely to suffer, affecting food production.

Filling the global water gap by supply measures alone would cost an estimated £124billion per year, a meeting in Canada was told.

But this could be cut to between £31billion and £37billion by an approach which both raised supply and lowered demand, according to leading water economist Dr Margaret Catley-Carlson.

It’s kinda interesting that no one takes future technologies into consideration when they try to predict the future and by not doing that all their models fail horribly. I mean do you really think that our technology will stay the same as it is now? If your answer is yes then you should do more research. So by 2020 we will probably use solar energy to desalinate seawater to supply humanity with an endless supply of fresh water.
