Water scarcity resulting from climate change is the number one issue the world will have to grapple with in the future, according to chief climate scientist and Nobel Peace Prize-winner Dr. Rajendra K. Pachauri.

On the one hand, we will have more water around us with sea level rising. On the other hand, though, drought caused by climate change will leave possibly billions of people without clean water.

This will cause great health and global security issues. Most of these problems will be caused by water imbalances.

The North American Great Lakes contain 6 quadrillion gallons of freshwater, about one-fifth of the world’s available freshwater supply.

For more than 25 years, residents of the Great Lakes region have feared large-scale public works projects to take freshwater from the Lakes to thirsty, faster-growing areas of North America. That’s why the eight Great Lakes states and Congress last year approved a compact barring most water diversions of the Lakes, which contain 80% of the continent’s fresh water. But ideas about turning the Lakes into a cash cow, floating around for years, are not dead yet. At the same time, relatively little attention has been paid to the idea of “sharing” the water of the Lakes to alleviate a global humanitarian emergency in an era of freshwater scarcity.

As land and water become scarce, competition for these vital resources intensifies within societies, particularly between the wealthy and those who are poor and dispossessed. The shrinkage of life-supporting resources per person that comes with population growth is threatening to drop the living standards of millions of people below the survival level, leading to potentially unmanageable social tensions.

Access to land is a prime source of social tension. Expanding world population has cut the grainland per person in half, from 0.23 hectares in 1950 to 0.10 hectares in 2007. One tenth of a hectare is half of a building lot in an affluent U.S. suburb. This ongoing shrinkage of grainland per person makes it difficult for the world’s farmers to feed the 70 million people added to world population each year. The shrinkage in cropland per person not only threatens livelihoods; in largely subsistence societies, it threatens survival itself. Tensions within communities begin to build as landholdings shrink below that needed for survival.

The Sahelian zone of Africa, with one of the world’s fastest-growing populations, is an area of spreading conflict. In troubled Sudan, 2 million people have died and over 4 million have been displaced in the long-standing conflict of more than 20 years between the Muslim north and the Christian south. The more recent conflict in the Darfur region in western Sudan that began in 2003 illustrates the mounting tensions between two Muslim groups–camel herders and subsistence farmers. Government troops are backing Arab militias, who are engaging in the wholesale slaughter of black Sudanese in an effort to drive them off their land, sending them into refugee camps in neighboring Chad. At least some 200,000 people have been killed in the conflict and another 250,000 have died of hunger and disease in the refugee camps.

“Water is the new carbon,” said Gil Friend, President and CEO of Natural Logic, during his moderation of a session on “The Outlook for Water Supply Shortages.”

The conference, held December 2 and 3 and organized by Green Power Conferences, engaged corporations to discuss how to become more proactively involved in the water management of their facilities. Companies such as The Coca-Cola Company, PepsiCo International, Nestle Waters, MillerCoors, and Cadbury were represented. Professors, water experts and consultants from a variety of firms, including Business for Social Responsibility and Natural Logic, also participated in panels.

There is a growing recognition that there are two convergent crises facing the world: energy and water. Scientific American launched a dedicated environmental publication this month, Earth 3.0, with the cover story Energy Vs Water. The article explores the dichotomy between the fact that we need energy to produce water and we need water to produce energy. As we are reaching Peak Oil, we also appear to be  approaching Peak Water. This creates an interesting dilemma—one which will require no small amount of innovation to solve.

Since the 1960’s, when Canadians learned of plans to privatize and divert large quantities of Canada’s water, many in the country have been wary that the US will view Canada as a “great, green sponge” and come after its water resources. They may not be far from the mark. Since he came into office, President Bush began using his dry home state of Texas in talks to push then Prime Minister Jean Chretien to turn on the tap of Canada’s water. Past US Ambassador to Canada, Paul Celucci, also made regular attempts to convince Canada that water should be a trade commodity, like oil. Moreover, in a time when much of the American public seems to rely on South Park for information about Canada, there’s very little understanding in the US about Canadians’ sensitivity over the issue of resource exports (and water exports in particular) to the United States.

First, the Department of Energy released a report that confirmed what the wind industry has already claimed: wind could power 20% of the United State’s energy needs by 2030. Even with growing energy demands, our ample wind resources could meet one-fifth of our needs with continued growth and innovation. Other nations, especially Denmark, are already deriving significant fractions of their energy from wind, sometimes with impressive results. The truth is, wind energy is booming even as the specter of the expiring Production Tax Credit moves to the House of Representatives for a vote.

Another large announcement this week came from ex-oilman T. Boone Pickens, who proved (once again) that every thing’s bigger in Texas.

He just ordered $2 billion worth of wind turbines from GE to build the world’s largest wind farm.
