Water Wars May Lie Ahead

By Neena Rai

There is a famous Chinese proverb that warns “not only can water float a boat, it can sink it also.”

And with global water shortages on the horizon, climate change supporters say an extreme response will be needed from international governments to stem the potential for conflict it will create around the world.

Professor Patricia Wouters at the IHP-HELP Centre for water law, policy and science at University of Dundee, said the world could face a future of “water wars” as deterioration in climatic patterns and global population growth leave people struggling to stake their claim to the natural resource.

The World Bank in a report said that 1.4 million people could be facing water scarcity by 2025. But the Organization for Economic Co-operation and Development (OECD) forecast is even more gloomy. It estimates that 47% of the world’s population could face water stress in the same period – equivalent to more than three billion people.

The issue isn’t restricted to countries that typically see temperatures soar, such as Cyprus, which in 2009 was forced to import water in tankers and ration its use. Northern hemisphere nations like the U.K. are also finding themselves in the midst of a drought in some regions, forcing governments to start to take action. The U.K. government, for instance, plans to issue a Water White Paper this December that will focus on the future challenges facing the water industry and measures to increase protection of river flows during summer months.

Parts of the U.K. are currently marked as having drought status and other areas of the country are deemed to be at risk of drought. The U.K.’s Department for Environment Food and Rural Affairs held a second drought summit Monday, at which Secretary of State Caroline Spelman warned the prospect of a dry summer and dry winter could have a serious impact on the country’s water reserves.

“We’re going to keep working with farmers, water companies and environmental groups to minimize the impacts of drought, because this year is sign of things to come,” she said. “The climate is changing and these extreme weather events will become more common. How we deal with that problem will be one of the key parts of our Water White Paper, which will be published later this year.”

This may be a far cry from a declaration of war on other more water-abundant nations, but reaching this stage in some countries isn’t beyond the realms of imagination. Egypt and Ethiopia have been battling the issue for the share of the Nile’s water reserves, and Israel – already fighting Palestine for territory that includes precious water reserves – has started to charge the agricultural sector high rates for using the resource.

Even in the U.K., the armed forces are being prepared for potential conflicts over water.

Professor Wouters said that military plans are being prepared on a 30-year horizon, but that the water security topic had somewhat fallen off the table since the financial crisis. Portugal and Spain are facing serious water scarcity issues but the agricultural sector there is having to shout loudly for its voice to be heard above the noise of the countries’ current financial woes.

Maybe Israel’s entrepreneurial approach to the issue is the way forward. Nevertheless, the fact remains that water scarcity is now firmly on the agenda of the world’s governments, and isn’t going to vanish overnight.
