Dubai's artificial islands have high environmental cost
The Price of "The World": Dubai's Artificial Future

From south to north, the artificial island sites in this image are Palm Jebel Ali, Palm Jumeirah, The World, and Palm Deira. Palm Jebel Ali and Palm Jumeirah appear largely complete in this image, looking like giant palm trees enclosed in huge arcs. Palm Deira, intended to be an even bigger palm tree when complete, is in the earliest stages of construction. In between Palm Jumeirah and the site for Palm Deira is the site for The World, which, when complete, will resemble a world map.

EDITOR's NOTE: Dubai, a city-state in the United Arab Emirates with a population of around one million, would be one of the world's smallest but wealthiest countries on its own thanks to the oil wealth of its inhabitants.
In addition to its penchant for acquiring records for the Guinness Book of World Records, Dubai has lately embarked on an ambitious plan to boost its international standing in the eyes of the world's rich (and its neighbors) by building a number of artificial islands. These islands, which will house luxury residences, villas, and hotels, are a growing concern for environmentalists due to their impact on the local marine ecology. Dubai should be concerned as well for the long-term viability of the plan -- rising sea levels from global climate change could spell trouble for its audacious and ostentatious investments. As Earth Island Journal puts it, "How ironic that the very people who drive rising sea levels through their businesses, which emit much of the world's greenhouse gases, will undoubtedly be some of the first to experience the devastating effects of climate change."
The Price of "The World": Dubai's Artificial Future
While there have been numerous articles written recently about the proliferation of artificial island projects, the astounding "The World" venture among them, few have addressed or assessed the environmental impact of such massive undertakings and the transformation of both the sea and landscape. Until recently, Nakheel, the government-controlled corporation developing these ambitious projects, has been able to focus predominantly on promoting rather than defending the islands, but new evidence of environmental detriment is bringing the company and its projects under fire from certain groups.
From the air, The World and Palm projects create a highly visible impression on the landscape of Dubai. And back down at sea level, significant changes in the marine environment are leaving a visual scar of another type. As a result of the dredging and redepositing of sand for the construction of the islands, the typically crystalline waters of the gulf of Dubai have become severely clouded with silt. Construction activity is damaging the marine habitat, burying coral reefs, oyster beds and subterranean fields of sea grass, threatening local marine species as well as other species dependent on them for food. Oyster beds have been covered in as much as two inches of sediment, while above water, beaches are eroding with the disruption of natural currents.
This optimistic outlook aside, another archipelago project, the Palm Jebel Ali, is located in a formerly protected marine reserve. The management of Jebel Ali marine reserve, the Persian Gulf's second most biodiverse marine system, was taken away from the Dubai Municipality Protected Areas Unit and passed over to Nakheel developers to build the island. Few can argue that the replacement of these natural formations with artificial structures can be a true substitute for what is being destroyed and result in a net gain in marine biodiversity. Further, ecologists fear that standardizing of the marine environment will alienate native species and encourage the likely introduction of new, foreign and possibly destructive species.
Palm Island Resort, Dubai, United Arab Emirates, is featured in this image photographed by Expedition 10 Commander Leroy Chiao from the International Space Station. The resort is under construction on reclaimed land silhouetted against the dark waters of Dubai's Persian Gulf coast. Advertised as "being visible from the Moon," this man-made palm-shaped structure displays 17 huge fronds framed by a 12-kilometer protective barrier. When completed, the resort will sport 2,000 villas, 40 luxury hotels, shopping centers, cinemas, and other facilities. When completed, the resort is expected to support a population of approximately 500,000 people. Photo courtesy of NASA.
Troubled waters are nothing new for Dubai or any other marine region. The health of the coral reefs has been in a state of continuous decline over the past 50 years. The Arabian Gulf is one of the most grievously affected areas, with recent estimates of habitat loss pegged at 35 percent. Increases in temperature and salinity have previously been attributed as the leading factors in reef habitat degradation, but the new pressure from dredging serves only to exacerbate the declining state of the environment.
Nakheel concedes that its various artificial archipelago projects have indeed buried reefs and changed the environment, but argues that the company will try to alleviate and even reverse some of the detrimental effects by building artificial reefs upon completion of the islands. What is more, the company has employed a marine biologist to monitor and rehabilitate damaged reefs. Imad Haffar, the research and development manager of Nakheel predicts local fauna will flourish in the newly constructed environment, but ecologists fear otherwise.
Environmentalists and scuba divers alike report that so much silt has been stirred up from dredging that organisms and the reef itself are slowly being choked by the sediment particles. The current activity has essentially destroyed Dubai's diving industry even if temporarily, and enthusiasts have left the area for clearer waters. Once dredging and construction are complete, the waters should clear, but will anyone recognize what has been left behind?

I just read your article on Nakheel's marine projects off the coast of
Dubai. I must say that it was very well written and I enjoyed it
If I can take a minute of your time, I'd like to pass on some news regarding the colonization of our Palm projects by a diverse array of marine biota.
Just recently we discovered that the channels between the fronds of the Palm projects seem to be ideal habitat for seagrass meadows. We've discovered large tracts of two species of seagrasses establishing in these areas. The protection offered by the crescent offers a sheltered environment favourable to seagrasses. The Palm Jumeirah crescent itself represents about 40 hectares of rocky reef. I dive on it every week and it is flourishing with invertebrate and vertebrate fauna. We've recorded dolphins, manta rays, sharks, trevally and more within the waters of Palm Jumeirah.
You've raised a good point though. There is a philosophical question as to whether habitat creation through rocky reefs, seagrass meadows and extensive intertidal beaches (70km on Palm Jumeirah) is sufficient mitigation for our island building activities. The previous habitat beneath the footprint of Palm Jumeirah was an open pelagic environs above denuded benthic sediments. Such habitat type is very important to numerous species, however, this habitat type is also very well represented in the Arabian Gulf. The richness of flora and fauna taking advantage of the habitat offered by our projects does indeed exceed the diversity previously found on the site. However, looking at the scale of our projects relative to the Gulf, this shift in the species composition is very minor and localized and most unlikely to have an adverse effect on the broader marine environment. In an ideal World, no one would interfere with any natural environment but at least our projects continue to provide healthy habitat unlike say agriculture, mining, most terrestrial residential developments or any project on a greenfield site for that matter.
