The Battle for Water

We are taught in school that the Earth has a closed hydrologic system; water is continually being recycled through rain and evaporation and none of it leaves the planet's atmosphere. Not only is there the same amount of water on the Earth today as there was at the creation of the planet, it's the same water. The next time you're walking in the rain, stop and think that some of the water falling on you ran through the blood of dinosaurs or swelled the tears of children who lived thousands of years ago.

While there will always be the same amount of water, we can render water unusable for ourselves and for the planet. The growing scarcity of potable water stems from a variety of causes. Per capita water consumption is doubling every 20 years, more than twice the rate of human population growth, which itself is exploding. Technology and sanitation systems, particularly those in the wealthy industrialized nations, have encouraged people to use far more water than they need. Yet even with this increase in personal water use, households and municipalities account for only 10 percent of water use.

Industry claims 20 to 25 percent of the world's fresh water supplies, and its demands are dramatically increasing. Many of the world's fastest growing industries are water intensive. For example, in the U.S. alone, the computer industry will soon use over 396 billion gallons of water each year.

Nonetheless, it is irrigation that is the real water hog, claiming 65 to 70 percent of all water used by humans. Increasing amounts of irrigation water are used for industrial farming. These water-intensive corporate farming practices are subsidized by governments and their taxpayers, and this creates a strong disincentive for farm operations to move to conservation practices such as drip irrigation.

Along with population growth and increasing per capita water consumption, massive pollution of the world's surface water systems has placed a great strain on remaining supplies of clean fresh water. Global deforestation, destruction of wetlands, dumping of pesticides and fertilizer into waterways, and global warming are all taking a terrible toll on the Earth's fragile water systems.

The world is running out of fresh water. By the year 2025, there will be 2.6 billion more people on Earth than there are today. As many as two-thirds of those people will be living in conditions of serious water shortage, and one-third will be living with absolute water scarcity. Demand for water will exceed availability by 56 percent.

Water as a commodity

The combination of increasing demand and shrinking supply has attracted the interest of global corporations who want to sell water for a profit. The water industry is touted by the World Bank as a potential trillion-dollar industry. Water has become the "blue gold" of the 21st century.

The move to privatize water coincides with the rise of the Washington Consensus as the dominant world economic philosophy. This philosophy calls for trade and investment liberalization, and turning responsibility for social programs and resource management over to the private sector. In this case, it is an assault on the ancient commons of water.

Global trade agreements have become perhaps the most important tool for corporations trading in water and their allies. All of the multinational governing bodies, the North American Free Trade Agreement (NAFTA), the General Agreement on Trade and Tariffs (GATT), and the World Trade Organization (WTO), define water as a commodity. As a result, water is now subject to the same rules and regulations governing other commodities, such as oil and natural gas. Under these combined international rules, a country cannot prohibit or limit the export of water without risking censure by the WTO. Nations are also restricted from denying the import of water from any country. NAFTA's "proportionality clause" means that if a country turns on the tap to export its natural resources, it cannot turn off the tap until it runs out of that resource.
