Artificial Islands:An Analysis of the Environmental Consequences
and International Legal Regime

Final PaperFall 2010
I. Introduction
The world’s population is growing persistently. In fact, the World Bank predicts that by
the year 2015, the global population will reach 7.1 billion.1 This figure represents an increase of
approximately one billion individuals over the course of 15 years.2 Without a doubt, this steady
rise will increase the strain on the available natural resources necessary for any given species to
thrive and survive,3 including land. Although habitable continental land may only be able to
support rapidly increasing populations for a finite duration of time, modern technology that
enables humans to build islands in the ocean where they would not otherwise exist may provide
relief. Between the sheer vastness of the oceans and the need to accommodate an overwhelming
number of people, the option is certainly attractive.
The history of such islands date back thousands of years.4 The earliest artificial islands
known were engineered for practical purposes such as protection from flooding and enemy
invasion.5 As early as the 1970s, artificial islands were seen not only as a solution to rapid
population growth, but also as fixtures that would one day be considered ordinary. As this idea
was put at the Conference on Seaward Advancement of Industrial Societies at the National
Academy of Sciences, “[b]arring a radical turn in the course of human events industrial societies
will advance seaward to the point that eventual ocean-sited urban/industrial complexes of some
size may become commonplace.”6 Consistent with the predictions of scholars, such projects are,
in fact, becoming increasingly common. However, manmade islands are now being engineered

for industrial and commercial purposes, and as time passes, they are being built increasingly
further away from shorelines.7
What exists today is a dichotomy between the current state of technology and human
advancement that enable the creation of manmade islands and the international legal regime that
governs their jurisdiction and construction. Put simply, the relevant laws have not kept in stride
with modernization. Unfortunately, while engineering and architectural expansion into the
oceans are certainly remarkable accomplishments, the price of progress is often paid in
environmental destruction. Recent island projects have proved harmful to the local ecosystems in
which they have been built and long-term consequences, though still largely under speculation,
are almost certain. If construction trends continue as predicted, the detrimental effects could
become widespread and irreversible.
The following sections seek to first identify the types of islands that are being built and
the functions they serve around the world. An overview of two specific projects will explore the
motives behind such immense endeavors and demonstrate the environmental impact that
succeeded the construction of each. Second, to explain the status of current international laws as
they are relevant to artificial islands. Third, to suggest changes to the existing legal regime that
would strengthen the commitment to environmental conservation while simultaneously
promoting sustainable seaward expansion.
II. The Facts
A. Artificial Islands Defined
To qualify as an artificial island, the installations must be “man-made, surrounded by
water from all sides, [and] above the water at high tide.”8 In addition, they must remain

stationary in the course of normal operation at sea.9 By meeting these criteria, manmade islands
follow at least a minimum standard of uniformity worldwide. Aside from this, however, the
islands that are springing up on coastlines are distinguishable because they vary in size, shape,
and distance from shore. Beyond this, and most notably, each nation that endeavors to undertake
such an enormous and costly project does so to serve a unique purpose based on that nation’s
individual needs. The follow sections seek to explore the various motives behind seaward
advancement, as well as the associated environmental implications.
B. Motives to Build Islands and the Functions they Serve
The seaward expansion phenomenon has spread worldwide, and this is hardly surprising.
As noted, the engineering capacity and resources are readily available. While there are countless
reasons a nation may opt to pursue this type of endeavor, one scholar has identified six broad
types of artificial islands: sea cities, islands for economic use, transportation and communication,
scientific investigation and weather forecasting, recreation, and military installations.10 Often,
islands retain characteristics of more than one of the above “types” because they are multi-
purpose endeavors. For example, as will be discussed in more detail below, Dubai’s Palm Islands
are sea cities that serve both recreational and economic purposes.
Broadly speaking, there are two main motives for a nation to construct an artificial island:
need and want. In reality, however, the two are often intertwined. For the purpose of this
analysis, two independent projects will be considered: the Kansai International Airport in Japan
and the Palm Islands in the United Arab Emirates (UAE). These are significant for various
reasons. First, because they are both ground-breaking, innovative projects that are setting the
standard for other nations that are following suit. Second, the motives for each project stand at

opposite ends of the spectrum. The Kansai International Airport falls represents “need” while the
Palm Islands represent “want.” Examining each will touch upon many of the most common
reasons individual nations opt to embark on such costly, large-scale projects. Third, each
presents a variety of environmental concerns. Thus, together the two provide a solid overview of
why and how islands are built, as well as the environmental implications inherent with such
projects.
1. The Kansai International Airport
Japan is a prime example of a country with a large population and few options for
expansion. Although the population growth rate is declining,11 the country still must
accommodate its 127 million people on a mere 145,902 square miles of land.12 In the mid-1980s,
this same dilemma was compounded by economic difficulties in the Kansai region as its cities
were struggling to compete with Tokyo, which handled a majority of the country’s imports and
exports.13 To compete, the region needed an international airport bigger than what was already
available,14 but finding the open land required for such an extensive project in a densely
populated country was next to impossible.15 Prompted by the need to spur the economy, an
absolute lack of space, and a desire to prove the country’s sophistication to the world,16 airport
officials decided to build in Osaka Bay.17
11 The U.S. Department of State reports that the estimated population growth rate in 2010 was -0.191%. See generally U.S. Department of State Background Notes: Japan, http://www.state.gov/r/pa/ei/bgn/4142.htm (last visited Nov. 12 2010).12 Id.13 Super Structures of the World: Kansai International Airport (Fireworks International television broadcast Apr. 14, 2000).14 The Osaka airport that already existed was both too small and situated precariously close to a residential area.

While building an airport at sea has certain undeniable benefits, including seemingly
unlimited space and noise reduction for nearby neighborhoods,18 building the Kansai
International Airport posed many problems, as well. The construction site was situated over three
miles from shore where the water reaches a depth of 60 feet.19 The island was to span over two
and one half square miles.20 In these respects, the airport’s plans marked many firsts in the arena
of artificial island construction: the farthest ever built from shore, built in the deepest waters ever
tested, and the largest in size.21 Prior to construction, engineers had never built on the diluvial
clay that lined the ocean floor,22 but predicted that the weight of an island coupled with that of a
massive airport would cause the entire structure to sink into the soft clay.23 Although experts
made various predictions on how far and how fast the project would sink by analyzing samples
of the ocean floor, officials opted to disregard the more cautious calculations in favor of those
that would allow them to save money.24
The building process itself was lengthy and overall successful thanks to the ingenuity of
engineers.25 To strengthen the clay layers, a five foot layer of sand was spread over the
construction site and one million columns of sand were drilled into the layers of clay.26 Next, a
wall of stones and concrete blocks were constructed around the area.27 Finally, workers
excavated three entire mountains to fill the area until it rose above sea level, creating the “land”
18 Id.19 Id.20 Id.21 Id.22 At the chosen site, there were two layers of ocean bottom clay. The first layer was the alluvial clay layer, which did not worry engineers because they had previously built structures on this type of sea bed before. However, below the alluvial layer was the dilluvial clay layer. These conditions were entirely new and nobody could predict with any certainty when construction began how the structure would work sitting on top of these two types of clay. See generally Id.23 Id.24 Id.25 Id.26 Id.27 Id.

on which to construct the airport.28 Before the airport itself was built, however, officials realized
that the island had already sunk more than had been allowed for under the predictions they opted
to follow.29 After adding extra layers of earth to the top of the already-sinking island, the
terminal was designed in a manner that would prevent it from cracking as the island continued to
sink.30
To this day, the island, though an overall success, is still sinking. This trend is expected
to continue for the next 30-50 years.31 Engineers have been able to overcome this problem for the
time being, but it has cost the company far more money than anyone originally anticipated.
Unfortunately, there is no certainty that these measures will continue to be successful for an
extended duration of time. Beyond this, the island still runs the risk of being destroyed by the
weather or natural disasters. Earthquakes and typhoons are both common occurrence in Japan,
and either could cause the liquefaction of the earth that was piled into the holding walls.32
Regardless, the airport and island have thus far endured the test of time for 15 years. A second
runway was recently built to ensure it remains competitive in Asian air transportation.33
2. The Palm Islands
In contrast to the earlier-built Kansai International Airport, the push to build the Palm
Islands in the United Arab Emirates was not driven by an absolute need to develop outward into
the sea, but it was similarly driven by an economic component. The UAE is a federation of seven
28 Id.29 The island was built based on predictions that it would sink 19 feet total. Before the airport terminal construction even began, the island had sunk 27 feet. Id.30 This was accomplished by including a ballast of 250,000 tons of iron ore to ensure that the terminal will sink at the same rate as the island.

states that was formed in 197134 and is situated along the Persian Gulf.35 The discovery of oil in
the 1960s allowed the country’s economy to flourish,36 but authorities have made efforts to
reduce the dependence on oil revenues by promoting the business, tourism, and construction
industries.37 In particular, tourism began to thrive. For example, in Dubai, the UAE’s main
commercial center, the tourism sector accounts for 22% of the city’s gross domestic product38
and had a goal of attracting 10 million tourists per year by 2010.39 However, because the entire
coastline had already been filled by hotels, the Palm Islands were proposed as a solution that
would meet daunting tourism goals by maximizing the amount of beachfront property
available.40
“The Palm Islands” is the collective name for three separate palm-shaped artificial
archipelago projects -- Palm Jumeirah, Palm Jebel Ali, and Palm Deira – that were built in the
Persian Gulf.41 All three islands were built with using the same engineering and construction
process,42 but each island constructed was bigger and more elaborate than its predecessor.43
Financing for such grandiose projects was obtained independent of banks. Described as “one of
history’s weirdest real estate pitches,” Dubai hosted the Arabian Travel Market trade show,
where people could purchase a portion of real estate on the soon-to-exist islands.44 Three-

quarters of the buyers were foreigners.45 Construction on Palm Jumeirah, the first of the islands,
began soon after in 2001.
The first task involved in creating the island was building the breakwater out of rocks to
protect the project from strong currents and winds.46 As built, it can withstand waves over 15 feet
and offers protection against rising sea levels.47 Once the crescent-shaped barrier was in place,
work began on the palm tree-shaped island began. This was done by configuring seven million
tons of rocks brought from quarries around the country and sand dredged from the Arabian Gulf
into the proper shape until they rose above sea level.48 To stabilize the sand and rocks, the
materials were compacted using a process known as vibro-compaction, in which the sand is
saturated with high-pressure water and air, and then vibrations were sent through it.49 This made
the structure sturdy enough to withstand the weight of the buildings to be constructed on top and
to withstand powerful earthquakes, rare as they may be in the area.50
A similar process was used to build the second two of the Palm Islands. Palm Jebel Ali,
however, was built on top of Dubai’s only protected marine area, where a coral reef once
thrived.51 Palm Deira, on the other hand, was only halfway through completion before the project
came to an abrupt stop due to financial troubles.52 Despite these setbacks, more similar projects
appear to be on the horizon for Dubai and other countries in the area. For instance, Nakheel
Properties, the developers behind the Palm Islands, already has plans for other islands in the
Persian Gulf that are expected to be as far as 12 miles from the shore and, if they pan out, will

double Dubai’s land mass and population.53 Similarly, Qatar, not to be outdone, embarked on a
similar endeavor when it began constructing The Pearl, a luxurious residential island that began
accommodating residents in 2009.54
C. Environmental Impact of Artificial Islands
Coastal areas,55 which have been explored and utilized by human beings for thousands of
years in a variety of ways, are home to an abundance of ecological resources, including
planktons, algae, and nutritional salts.56 The construction of artificial islands near shorelines has
a measurable effect on these organisms. After all, these resources are the backbone of regional
ecosystems: they serve as food for organisms higher on the food chain, act as water purifiers, and
prevent wave and sand drift.57 When damaged or destroyed, the area takes a significant amount
of time to return to its original form.58 This is why an increase in large-scale coastal projects,
such as manmade islands, could have a disastrous effect on the world’s oceans. An overview of
the subsequent environmental issues that arose from two projects discussed above provides
insight to the potential hazards that could become widespread if the construction of islands
continues.59

Additionally, it should be noted that any change, even seemingly small ones, can throw an ecosystem off balance. This means that with both projects, simply constructing the islands alone – dredging and adding sand that is not native to the environment – was capable of damaging the ecosystem. Exclusion from the analysis does not imply that they are insignificant impacts, but rather that they are the obvious side-effects of offshore construction. The analysis will focus on damages that are less often focused on.

1. The Aftermath of the Kansai International Airport
Prior to the construction of the Kansai International Airport, the prepared environmental
assessment report identified a handful of possible adverse effects on Osaka Bay, including noise,
air, and water pollution, seabed quality, seascape, radio wave interference, and marine animal
and bird habitation.60 The predicted impact of the island and airport complied with Japan’s
environmental protection regulations in 1985, allowing the company to go forth with its building
plans.61 Despite compliance with existing laws, the airport was not built without moderate
amounts of damage to its surrounding environment.
Aside from the aforementioned devastation of plankton and other organisms that support
the regional ecosystem inherent in any coastal development project, the impact on fisheries and
seaweed beds drew attention. Even prior to construction, officials knew that construction would
disrupt Osaka Bay’s fishing industry.62 Altering the conditions of the water would change the
migration patterns of fish living in the Bay, patterns the local fishermen knew well and depended
on.63 The Kansai International Airport Company negotiated with fishermen and agreed to pay
them exorbitant amounts of money to compensate for the loss of fisheries.64 This gave the
fishermen assurance that they would still be able to sustain themselves and the company could
proceed without worrying about strikes impeding progress.65
Similarly, seaweed beds in the area also deteriorated due to the construction of the island.
These beds play various important roles in the environment, including providing food and shelter
to commercially important fish and birds, absorbing carbon dioxide and discharging oxygen, and

serving as buffers of coastal water quality.66 Kansai International Airport, and the other similar
islands off the coast of Japan, has contributed to the depletion of the country’s once immense
supply of seaweed beds.67 To compensate for this problem, gentle slopes were built along the
perimeter of the island and adult plants are attached; this allows seaweed to grow and encourages
the restoration of the area’s original habitat.68 Even if this approach is ultimately successful, it
will be a slow, lengthy process.
As seen, in the case of both fisheries and seaweed beds, officials made the effort to
rectify problems they knew they were causing. However, as one scholar points out, neither of
these solutions is perfect because they are not ecological-based.69 Ideally, future efforts should be
focused on the habitat.70 While these problems appear to only affect the regional ecosystem, they
could have more widespread effects that are not yet apparent. Seemingly small human actions
can cause a tremendous impact. After all, deterioration of one link of the food chain will
inevitably have an effect on other levels.
2. The Aftermath of the Palm Islands
While the Palm Islands’ predecessors like the Kansai International Airport may have
escaped mainstream criticism fairly unscathed, the UAE’s projects were widely attacked by
environmentalists. In 2006, the World Wildlife Fund (WWF) announced the “UAE's human
pressure on global ecosystems (its ecological footprint) to be the highest in the world.”71 While
this ranking cannot be solely attributed to the artificial islands,72 they undeniably put a strain on
66 Kazuo Okuda, Coastal Environment and Seaweed-bed Ecology in Japan, 2-1 Kuroshio Sci. 15, 17 (2008). 67 Id.68 Id. at 18.69 Id. at 19.70 Id.71 The Impact of the Palm Islands: Environmental Impacts, http://sites.google.com/site/palmislandsimpact/environmental-impacts (last visited Oct. 18, 2010).72 The UAE ranked first for ecological footprint because energy consumption and carbon emissions are both high. Even though the UAE is a signatory state to the Kyoto Protocol on Global Warming, it is not required to cut emissions because it is considered a developing country. See generally Jim Krane, UAE Beats Americans’

the environment. As one critic put it, “[t]he profound underwater changes currently taking place
as a result of construction are only matched by the grandiose vision of Nakheel developers.”73
Even within a decade, the short-term consequences of large-scale island construction are already
becoming obvious, while the extent of future problems remain relatively unknown.
Similar to the case of the Kansai International Airport, the marine biota that flourished at
the construction site were decimated by the island-building process. While the UAE claimed that
no sea life existed in the area to begin with74 and public statements stressing that construction
would not harm marine life – more specifically, coral – were issued,75 this has long been
recognized as false. In fact, the seabed was rich with plankton, grasses, algae, oysters, coral
reefs, etc.76 However, the dredging necessary to redistribute the sand caused the organisms to
take flight, buried them,77 or asphyxiated them.78 The United Nations University Institute for
Water, Environment, and Health concluded that uncertain amounts of coral reef were damaged79
and “permanently modified wave patterns and coastal currents.”80 In short, even the marine biota
that were not killed during or because of construction was inevitably affected by the disruption to
the habitat, from loss of habitat and food.
Beyond the effects on marine life, the Palm Islands have also caused several other
problems, both environmental and economic. First, the construction of the islands have changed
the height and direction of waves near shore which has, in turned, caused erosion problems for

both the newly constructed islands as well as the shore of the mainland.81 One shoreline model
simulation predicts varying degrees of damage to different points along the coastlines and notes
that the breakwater may collapse or fail to serve its purpose.82 Second, there have also been
economic ramifications. Not only has the displacement of fish affected the local fishermen,
certain aspects of tourism, such as the scuba diving industry, have suffered as a result to the loss
of coral reefs, fish, and clear water.83
D. Conclusions
Artificial islands are becoming increasingly popular options for nations worldwide for a
variety of reasons. As the Kansai International Airport and Palm Islands demonstrate, motives
are complex and intertwined, often a combination of economic need, lack of space, and a desire
to prove something to the world. These projects in particular have set the path that other nations
are following. While newer islands may be able to learn from past engineering and architectural
mistakes, there are obvious environmental issues that are unavoidable regardless of which
construction methods are utilized. Even more worrisome is that there are certainly long-term
consequences that are not yet apparent. For the time being, however, manmade islands are not
common offshore fixtures. Still, they are well on the way. For this reason, the environmental
implications should be brought to the foreground. The rising momentum for similar projects
around the globe suggests that it is time to reconsider the international legal regime that governs
artificial islands.

III. Current Laws
The United Nations Convention on the Law of the Sea (UNCLOS) was produced in
response to the increasing exploitation of the oceans.84 By the late 1960s, “[a]ctivities unknown
barely two decades earlier were in full swing around the world,” including oil exploration,
mining, and over-fishing.85 To prevent the total destruction of the oceans, the United Nations
called for the creation of “an effective international regime over the seabed and the ocean floor
beyond a clearly defined national jurisdiction.”86 Beginning in 1973, over 160 sovereign states
came together to discuss pertinent issues and negotiate what would become the provisions of
UNCLOS, which was adopted nine years later in 1982.87
The international laws governing artificial islands are contained in UNCLOS, but they
are not at all extensive. Part V of the Convention deals with the legal regime of the exclusive
economic zone (EEZ). The EEZ is “an area beyond and adjacent to the territorial sea”88 that
“shall not extend beyond 200 nautical miles from the baselines from which the breadth of the territorial
sea is measured.”89 According to Article 56 of the Convention, coastal states have sovereign rights
over the exclusive economic zone “for the purpose of exploring and exploiting, conserving and
managing the natural resources, whether living or non-living.”90 It additionally states that coastal
countries have jurisdiction over the establishment and use of artificial islands within their
respective EEZs.91

Article 60 of UNCLOS goes into further detail about artificial islands. It provides that
“the coastal State shall have the exclusive right to construct and to authorize and regulate the
construction, operation and use of artificial islands.”92 This provision further provides several
specific requirements for states that wish to construct an island in the EEZ. First, prior to
construction, due notice must be given and “permanent means for giving warning of their
presence must be maintained.”93 Second, where necessary, a state may establish safety zones of
no more than 500 meters around the island and that are reasonably related to the nature of the
island to ensure navigation safety; these zones also require due notice be given.94 Islands may not
be constructed in locations that would cause them to interfere with international navigation, such
as recognized sea lanes.95 Within this article of the Convention, the environment is explicitly
mentioned once. However, it is only in the context of islands that have been abandoned that must
be removed out of respect for, among other things, the environment.96
IV. Proposed Law
The international legal regime of artificial islands set forth in UNCLOS is inadequate in
light of emerging trends in coastal engineering. The provisions of the Convention give coastal
states a great deal of latitude in determining where, when, and how to construct artificial islands.
As discussed, artificial islands are becoming increasingly popular in the shores of coastal
nations. As drafted, there is extremely little concern for the environmental problems caused by
massive island construction projects in territorial waters. If left unrevised, these international
laws of artificial islands will continue to accept the unnecessary decimation of coastal
ecosystems.

As a preliminary matter, it is important to establish that state sovereignty is an important
aspect of international law that cannot be overlooked. State sovereignty gives nations
independence, the right to “exercise . . . the functions of a State such as the exercise of
jurisdiction and enforcement of laws” to the exclusion of other states.97 In other words, it gives
each country the right to govern independent of other states. However, state sovereignty stands at
odds with the fact that environmental problems are often global in nature, and improving
environmental conditions require cooperation among states.98 For this reason, while the
international laws that govern artificial islands should not mandate with specificity exactly what
states may and may not do when planning and constructing an island, they can – and should –
provide a framework that will allow individual nations to enforce environmental laws through
national legislation.
There are several revisions that could be made to the existing international laws that
govern artificial islands to strengthen the Convention’s commitment to environmental
conservation. Each of these revisions revolves around explicitly addressing the environment
within Article 60, which provides states with several guidelines to follow for the construction of
manmade islands. First, the laws should mandate that, prior to beginning construction of an
island, states should not only give due notice, but they should also be required to formally assess
multiple construction sites and building plans to determine which will have the least negative
impact on the surrounding ecosystems. This will require states to research construction sites, the
interactions of different species within the regional ecosystems, the implications of different
construction materials and methods, and which options are financially feasible.

By requiring assessment reports, Article 61, which states that nations shall ensure through
proper conservation and management that over-exploitation will not endanger the marine
resources,99 will be implicated. If a state is required to consider its options, it cannot claim
ignorance if the island it builds decimates entire populations of species. In essence, this revision
to the law will seek to promote accountability and a sense of responsibility to the local
environment. Beyond this, a mechanism that compels states to weigh its options will hopefully
steer it away from making decisions solely based on finances. For example, as was the case for
the Kansai International Airport directors, putting a budget ahead of the more conservative
scientific predictions turned out to be more costly in the end because the island began to sink far
more rapidly than the building strategy planned for.
Another revision that will promote environmental conservation is to create classifications
of protection for different marine environments. Although all organisms deserve equal protection
under law, this may not always be viable in light of increasing pressure on populations to spread
seaward. Locations that are rich in natural resources, living organisms, and that provide local
individuals with the source of their incomes should be given the highest degree of protection
under this system of classification. States will only be allowed to build islands in these areas in
exceptional circumstances.100 On the other hand, where there are fewer resources, organisms, and
less human dependence on the area, that area will be given a lower degree of protection. States
will be allowed to build in these locations only after they have acted in compliance with the
assessment reports provision described above to ensure its construction has the least detrimental
effects possible.
99 United Nations Convention on the Law of the Sea art. 61, Dec. 10, 1982, 1833 U.N.T.S. 397.100 For example, this type of provision would have prevented the UAE from construction the second Palm Island directly on top of its only protected marine environment.

One last addition to the laws would be to add a provision that increases a nation’s
responsibility to the environment even after an island is built. Without a doubt, progress should
not be hindered, but neither should it cause irreversible destruction. To promote sustainability,
UNCLOS should be altered to mandate that nations may only be allowed to construct islands as
quickly as the ecosystems can restore themselves and states should take every reasonable
measure to promote habitat restoration at construction sites. This provision will prevent nations
from building many islands within a relatively small geographic area101 without regard for
whether the natural resources can keep up. In addition, it will encourage nations to build in the
least destructive manner possible and take additional steps that will help attract the same
organisms that lived in the area prior to construction.102
These revisions and additions to the existing law will create an international framework.
From there, states can decide how to meet these goals through more specific national legislation.
For example, states will have the authority to mandate what exactly the environmental
assessment reports will entail and which sites are viable for building. Although it will impose
some limits on what each individual nation is allowed to do, it will still allow plenty of leeway so
that sovereignty is not entirely curtailed. States will still be allowed to build projects, but will
have to do so in a more environmentally-conscious manner. The approach, though imperfect,
attempts to promote research prior to construction and environmental sustainability without
impeding human progress.
V. Conclusion
Artificial islands will very likely become common fixtures in the future. Research and
recent projects show the various short-terms effects this will have on the environment, and long-

term impacts are still relatively unknown. At present, the laws that govern the jurisdiction and
construction of manmade islands fail to adequately address the implicit environmental concerns.
However, there is still plenty of time to revise the laws. Alterations should be made to the laws to
ensure that human development may continue to consistently develop while still promoting
environmental conservation and sustainability.
