Facing Water Woes, Abu Dhabi Greens the Desert

Abu Dhabi, UAE, March 31, 2008 — -- Across the Persian Gulf, oil-rich Arab cities are turning sand into skyscrapers, investing in and profiting from one of the world's greatest construction booms.

Dubai is building the tallest tower on Earth. The prestigious Louvre and Guggenheim museums are moving ahead with plans to open branches in Abu Dhabi.

Manama, the capital of Bahrain, has announced plans to build its own set of man-made islands.

But to grow takes water, and water is scarce in this desert-dominated region. Abu Dhabi, often called the richest city in the world, is 90 percent desert. With hot weather and high standards of living, the United Arab Emirates, home to Dubai and Abu Dhabi, has the highest water consumption per capita in the world, by some estimates.

Water doesn't come cheap in the UAE, a country where it costs more there to produce a gallon of water than a gallon of oil. Most water for domestic consumption comes from desalination, an expensive and energy-intensive process that purifies water drawn from the salty Persian Gulf. The fresh water is then piped into the homes, hotels and commercial buildings multiplying along the Gulf coast.

As construction expands so must key infrastructure, putting a strain on public services like water consumption and wastewater management.

"There is no economic growth without water," said Mohamad Dawoud, a water specialist with the Abu Dhabi Environment Agency.

"We have a rapid growth and a lot of infrastructure that needs water. You need recreation areas, parks, national parts and the green areas in the city, and this is a big challenge for the government," Dawoud told ABC News.

Water conservation efforts have begun to take shape in the Emirates, but construction megaprojects and an 8 percent annual population growth threaten to outstrip the scarce reserves of this desert country. Government figures show if the desalination plants shut down in an emergency, the UAE's public supply of water will last no longer than 24 hours.
