There are a number of encouraging examples of cities trying to slowly evolve themselves into a vision of urban sustainability. Implementing bike infrastructure, upgrading the ecology of alternative transit, increasing recycling and addressing the state of our energy production systems are all noteworthy efforts being tackled by numerous cities around the world. But despite the show of goodwill, there are other examples that force one to wonder if we are simply taking two steps back for each that we take forward. The city of Dubai, rising in defiance to the surrounding environment of coastal deserts in the United Arab Emirates, stands as the hallmark of a digressing trend taking us farther away from the goals of a new cultural reality. As a poster child of modern ingenuity driven by the perpetual desire of humanity for unbounded excess, the city of Dubai casts a long shadow over our path to a greener future.
Originally sited for its coastal access to shipping trade, the city has exploded infinitely from its historical size. With the discovery of oil in the mid 1960′s money flooded into the region, beginning to fill coffers that could one day be leveraged to lift life and prosperity out of the sands. Over the past quarter-century Dubai has fashioned itself as a temple to the unusual feats of how nature can be bested by humanity. Islands can be coaxed to rise from the sea. Mountains of snow can sit amidst lashing heat. The world’s tallest tower can sit in the sand and be visible for miles around.While the city lacks a Magic Kingdom, Epcot Center or its own Universal Studios, make no mistake–the creation is just another Disneyland, an attraction meant to draw people from around the world to be awed and impressed at the surreal.
Prone to sudden, heavy rains, sandstorms and hot, arid temperatures, the surrounding landscape has provided no shortage of reasons for why not to build a city in the desert, but the gait of the government-funded movement has been unfettered. The fact that sand is not the ideal medium for siting high-rise development did nothing to temper the race to build a current estimated stock of 43.6 million square feet of office space. One thing that natural ecosystems and capitalism have in common is a concept of supply and demand, equalizing forces that help balance population or production. Dubai, however, seemed to ignore such indicators given that according to Jones Lang LeSalle, the current vacancy rate for its commercial space is near 33%–a number that could rise as high as 65% with the new construction projects already in the pipeline. For comparison, the vacancy rate for office space in New York City was 11.1% in January and falling.
Of course, the crown jewel of Dubai’s high rise bonanza is Burj Khalifa, formerly known as the Burj Dubai and designed by architecture firm Skidmore Owings and Merrill. Towering 2,625 feet into the air, the building boasts the title of the tallest structure in the world. Amongst the 160 floors is a combination of residences, commercial office space, an observation deck and the Armani Hotel. Undeniably, the building is a testament to the capabilities of engineering. Getting glass and steel to stand a half-mile into the air in the middle of the desert is no easy task, one accomplished by using 110,000 tonnes of concrete to pour 192 piles that descend 540′ below the surface. Given the height of the building and high temperatures during the day, the pumping and pouring of the higher concrete floors was done at night where the curing process could be more gradual to avoid cracking and subsequent future instability. All impressive achievements, but necessary?
And yet within months of opening, the observation deck at the tower has already been closed to tourists indefinitely while precise reasons for the closure were unspecified. I found one tourist’s disappointment rather ironic. “It was the one thing I really wanted to see. The tower was projected as a metaphor for Dubai. So the metaphor should work. There are no excuses.’’ On the contrary, I think that the fact that the tower is a metaphor for Dubai is exactly why it does not work. It is a city destined to be punished for its misguided battle against an inexhaustible force: nature.
Unsurprisingly, there is not enough natural water to supply a city of over 2 million people in the desert. Instead taking such an impediment as cause for consideration, the city looked to the oceans. As of 2007, the city had a desalination capacity of 188 million gallons per day. Ocean desalination is a fleeting attempt at cheating the climate, requiring enormous amounts of energy. In her essay featured on The Oil Drum, former Mayor of Huntington Beach, CA, Deborah Cook notes that “The next worst idea to turning tar sands into synthetic crude is turning ocean water into municipal drinking water. Sounds great until you zoom in on the environmental costs and energetic consequences…There is no more energy intensive water source than ocean desalination.” It is important to note that Dubai residents are not exactly the image of conservation. With their swimming pools, fountains and lush green lawns, the emirate used 10% more water than the average American (formerly the largest consumer in the world) and six times more per capita than nearby Jordan as of 2009. Hundreds of thousands of barrels of oil and gas will be used to power these efforts in the years to come.
The World Wonders of Excess:
And then there are the islands. Oh, the islands. Construction began on the Palm Jumeirah island in June 2001. 94 million cubic meters of sands, 7 million tonnes of rock and $12 billion later, we have artificial islands in the shape of a palm tree. Eventually the island will be joined by the finished likenesses of Palm Deira and Palm Jebel Ali. At this point, Dubai World would not have to worry about being outdone by foreign endeavors (who else would build islands in the middle of the ocean) so they had to resort to trumping themselves. Started in 2003, the 300 world islands have risen from the waters only to halt in construction as Dubai developer Nahkeel recoils from $26 billion in debt.We can only hope it is never repaid.
Each of these islands requires the dredging of the ocean floor to lift sand up onto its new home. The damage to the aquatic ecosystems in the form of waste, pollution and noise must be far-reaching. Not to mention we have already seen what can happen when people decide to build a city on a Louisiana swamp lying somewhere in the vicinity of sea-level. While the coast of Dubai may not be in a prime path for hurricanes, creating a series of islands against the natural correlation of water movement in the middle of the ocean is destined to have future problems of maintenance and structural issues. We are in a world where regardless of the fact that island nations are at risk of being eradicated due to rising sea levels, oil funds are put towards building new islands in the water.
Perhaps the only thing that can trump the world’s tallest tower and man-made islands is Ski Dubai, an interior ski resort fashioned right in the middle of the desert. The experience comes equipped with multiple trails, life-like snow, chair lifts and temperatures of -5 degrees Celsius. Once again, the structure is architecturally impressive due to the level of engineering required to keep snow from melting with outside temperatures as high as 50 degrees Celsius (that’s 122 degrees Fahrenheit.) The wall is actually a double-skin construction with two high-insulating layers separated by an air-gap that serves as a buffer for heat transmission. In theory the system is similar to a double-skin glass curtain wall like the one in One Bryant Park that faces the New York Public Library and holds small interior gardens. Nevertheless, it should have been enough to know that such a feat could be accomplished. There is no pride to be taken from achieving a luxury at a limitless cost of energy and resources.
As an oasis of extravagance built as a tourist trap, Dubai is a frightening reality. There is no better urban example of disregard to the environment as it resets the limit of how far from rational evolution we will travel before we decide to turn around and retrace our steps. This is not the example we should be setting for developing nations who may soon encounter the ability to craft their own cities in the landscape. I find any mention of “sustainability” linked to this city insulting and degrading. Such efforts are beyond simply “greenwashing,” but rather dipping a project in a vat of green tinted resin before dumping the waste into a landfill built over an aquifer.
But we can travel up 160 floors on elevators going 25mph to look out over a series of islands completed fabricated by humans! Aren’t you impressed? Quite simply, no. I already have the utmost of confidence in humanity’s abilities in science and technology without wasting $4 billion to make a giant spire in the desert. Perhaps there is a silver lining yet. Dubai’s very existence epitomizes the opposite of sustainability. Its logical course is destined for failure with 25% of its economy based on property and construction–a service that is limited and threatened by rising vacancies and a world recession. Such an urban downfall may help hit home the concept of such hollow endeavors and help justify the efforts of local cities to distance themselves away from new urban theme parks. Maybe the loss of billions of dollars in investment capital may help lenders not make the same mistake again when some group of innovators decide they want to build a resort at the bottom of the ocean or open golf course on the slopes of a volcano or plant a massive orange grove on the peaks of the French Alps.
