The reclamation of land from surrounding waters is used in Singapore to expand the  city-state’s limited area of usable, natural  land. Land reclamation is the process of creating new land by building outwards into local bodies of water. There are several different methods of reclaiming land, but the most basic approach involves the importation and dumping of large amounts of heavy rock and/or cement into the desired waters, creating a firm base onto which  clay and  dirt are added until the anticipated new land height is reached. Draining submerged wetlands or similar biomes in order to recover land also classifies as land reclamation.

Similarly useful to the relatively small, coastal territories of Hong Kong and Macau, the process of land reclamation allows for increased development and urbanization. Each of these coastal territories is restrained by its geographical boundaries, and is thus traditionally limited by the ocean’s reach. The use of land reclamation allows these territories to expand outwards by recovering land from the sea.

Land reclamation has been used in Singapore since the early 19th century, extensively so in this last half-century in response to the city-state’s rapid economic growth. At just 719 square kilometers, the entire country of Singapore is smaller than New York City (which is in fact almost one million square kilometers larger). , As such, the Singaporean government has found it necessary to reclaim land. Land reclamation projects have been used to supplement the city-state’s available commercial, residential, industrial, and governmental properties (the last of which entails military/official buildings). Land reclamation in Singapore also allows for the preservation of local historic and cultural communities, as the pressure for new land is lessened by the reclamation of land from the sea.

In 1960, Singapore was home to less than two million people; that number had more than doubled by 2008, to almost four and a half million people. To keep up with such an increase in population (as well as a concurrent surge in the country’s economy and industrialization efforts), Singapore has increased its land mass by 22% since the city-state’s independence in 1965, with land continuously being set aside for future use. , Though Singapore’s native population is no longer increasing as rapidly as it was in the mid-twentieth century, foreigners continue to flood into the city as the economy thrives, resulting in a continued investment in land reclamation by the Singapore government. , The government thus plans to expand the city-state by an additional 7-8% by 2030.

History


The early phases of land reclamation began not long after Sir Stamford Raffles arrived in what would become modern Singapore in 1819. Raffles had come to the area with the goal of developing a British port to rival that of the Dutch, and though contemporary Singapore was the ideal location for a harbor, it was at the time comprised of only a small fishing village. , undefinedConverting this village into a significant trading center required reorganization and better utilization of the land. After some alterations to his original plans, Raffles decided in 1822 that the commercial center of his new port should be located on the south bank of the Singapore River, close to the river’s mouth. At that time, the south bank was largely swamp area, covered in mangrove trees and sprinkled with creeks. As such, the land was also unoccupied. Though Singapore’s first British Resident, William Farquhar, expressed concerns about the cost and feasibility of reclaiming this land, it was eventually decided that the project was achievable. The southwest bank of the river was found to be prone to flooding, so Raffles decided to dismantle a small hill (located in today’s Raffles Place) and use the soil to raise and fill in the low-lying areas that would otherwise be affected by flooding. The project began in the second half of 1822, and was completed in three to four months (largely by Chinese, Malay, and Indian laborers). Once completed, the south bank was broken up into lots, which were then sold off to commercial investors.

After this first land reclamation project, there were no significant alterations to Singapore’s geography until 1849, which brought the building of port facilities that became increasingly important after the establishment of the British Straits Settlements in 1826 and the opening of the Suez Canal in 1869, both of which allowed for improved connections between the city-state and Europe. ,

After the turn of the century (particularly during the years 1919 to 1923), Singaporean land reclamation was primarily the result of a need for increased public utilities (including the construction of transport links, such as roads and railways) and military coastal protection. This development largely continued until World War II, when the Japanese occupied Singapore. The Japanese directed focus away from an improved Singapore and towards an extended Japanese culture, establishing a Japanese school and showing Japanese propaganda films in cinemas. There was thus a low rate of industrialization in Singapore during this period, a lull which continued throughout the 1950’s and early 1960’s (during which time Singapore experienced extensive political change) until the city-state’s participation in the founding of Malaysia in 1963. , As part of Malaysia (and continuing after independence in 1965), Singapore benefitted from economic development programs, which both enabled and required significant land reclamation projects. The city-state experienced a rapidly-increasing demand for industrial, infrastructural, commercial, and residential land, resulting in projects that reclaimed hundreds of hectares at a time. The Jurong Industrial Estate began development in the early 1960’s to meet industrial land needs, and by 1968 already housed 153 factories, with 46 in the midst of the construction process. Little, however, remains of the original Jurong, with much of the area’s original geography restricted to the areas around the Pandan Reservoir and Sungei Pandan. At around the same time as the development of the Jurong Industrial Estate, Singapore’s central business district (CBD) was similarly extended into land reclaimed from the sea. In this manner, Singapore’s weak economy was transformed through post-war industrialization and land reclamation.



In 1981, Singapore Changi Airport opened after the clearing of roughly two square kilometers of swampland and the introduction of over 52,000,000 cubic meters of land- and seafill. As Changi Airport maintains a policy of continual development in preparation for the future, a third airport terminal was planned from the beginning, and was opened on the first day of January, 2007. Changi Airport was voted the best airport in the world every year between 2013 and 2016.

By 1991, 10% of Singapore was comprised of reclaimed land. By that year, industrial land on Singapore’s mainland had again grown scarce, and it was decided that seven islets south of Jurong would be merged to form one large island (today’s Jurong Island). By 2008, Singapore was one of the top three oil trading and refining hubs globally.undefined The necessary facilities for such an involvement in the oil industry requires an incredibly large amount of space, and today, Singapore’s facilities are housed almost entirely on Jurong Island and the Jurong Industrial Estates.

In 1992, the Marina Centre and Marina South land reclamation projects were completed after their commission in the late 1970’s, encompassing 360 hectares of waterfront development. The land reclamation process involved the removal of the Telok Ayer Basin and Inner Roads; the mouth of the Singapore River was also rerouted to flow into Marina Bay rather than directly into the sea, as it had naturally. The total Marina Bay project added significant waterside land adjacent to Singapore’s central business district, creating prime real estate that is used for commercial, residential, hotel, and entertainment purposes today.

Singapore continues to develop and expand, with current land reclamation projects currently under construction, and plans for an additional 7-8% of reclaimed land to be added to Singapore by 2030. ,“6-178e energy, see

Recent difficulties with sand mining
Land reclamation requires by nature a substance to fill in land reclaimed from the sea. In the case of the shallow waters surrounding much of Singapore, sand has been chosen as the best option for this process. Sand isn’t necessarily always used to fill in land (as noted earlier, Stamford Raffles used soil from a razed hill to raise the southwest bank of the Singapore River), but it is often the main substance involved with Singapore’s land reclamation. In fact, Singapore has used so much sand that it has run out of its own stores, and looks to import sand from surrounding areas in order to meet its land reclamation needs. Though industries around the world depend on sand, the United Nations Environment Programme found Singapore to be the largest importer of sand worldwide in 2014. In 2010 alone, Singapore imported 14.6 million tons of sand.

In recent years, however, sources of sand have become more scarce. In 1997, Malaysia announced a ban on the export of sand. Yet, local media continue to report rampant smuggling of sand into Singapore, leading Former Prime Minister Mahathir Mohamad to protest that these corrupt sand miners were “digging Malaysia and giving her to other people.”



In 2007, Indonesia enacted a ban against exporting sand specifically to Singapore. This ban followed tensions between Singapore and Indonesia regarding islands lying between the two countries: sand miners had reportedly all but demolished these islands, leaving barely anything behind. In 2007, more than 90% of Singapore’s imported sand had come from Indonesia. The ban resulted in an increase in constructions costs as well as the need to find new sand markets, the latter of which Singapore has increasingly struggled with as more of its neighbors institute their own bans and regulations regarding the exportation of sand.

In 2009, Vietnam followed Malaysia and Indonesia with its own ban against the exportation of sand to Singapore.

Also in 2009, Cambodia announced its own ban, though this country’s prohibition was less all-encompassing than those of its predecessors: though sand from some seabeds could still be exported, river sand could no longer be dredged and distributed. More recently, however, certain rivers that receive replenishments of sand naturally due to their proximity to seawater have been made exempt from this ban. In spite of these restrictions, Cambodia is now Singapore’s primary source of sand. Having provided just 25% of Singapore’s sand imports in 2010, this increase has dramatically changed local ecosystems. After the dredging of Cambodia’s Tatai River (exempt from the ban) began in 2010, locals saw an estimated 85% reduction in the catch of fish, crab, and lobsters; tourist numbers have similarly decreased as the amount of construction and noise have surged. Local Cambodians have petitioned for the end of this sand mining. Large-scale damage has been seen throughout the Cambodian province of Koh Kong Province as a result of this dredging.

The Singaporean government refuses to disclose where the sand it receives is imported from. The Ministry of National Development has said that the government buys sand from “a diverse range of approved sources”, but maintains that further details are not public information.

Starting in November 2016, Singapore has started to use a new land reclamation method called the polder development method. Used by the Netherlands for many years, this method involves the building of a wall to keep out seawater from a polder, or low-lying tract of land, while drains and/or pumps control water levels. Use of the polder development method should lessen Singapore’s reliance on sand for its land reclamation projects. The method will first be used in Singapore on the northwestern tip of Pulau Tekong, a future military training base which will be expanded by 810 hectares.

Controversy with Malaysia
In 2003, Singapore received backlash from Malaysia over land reclamation projects at either end of the Straits of Johore, which separate the two countries. Malaysia claimed that Singapore’s plans infringed on Malaysian dominion and were detrimental to both the environment and the livelihoods of local fishermen. Malaysia legally challenged Singapore under the UN Convention on the Law of the Sea (UNCLOS). The dispute was settled after arbitration.

More recently, however, Singapore has issued its own complaints against Malaysia regarding the latter’s two land reclamation projects in the Straits of Johore. One project would involve the creation and linkage of four islands within the strait, creating a new metropolis called Forest City. Malaysia plans to advertise Forest City as a garden oasis, with buildings covered by greenery and an impressive expanse of public transport. Progress on the project came to a halt after Singapore protested its construction in 2014, but the Malaysian government reportedly approved a scaled-down version of the project in January 2015.

Environmental consequences
Singapore’s industrialization (particularly in terms of coastal development) and land reclamation projects have resulted in the extensive loss of marine habitats along the city-state’s shores. The large majority of Singapore’s southern coast has been altered through the process of land reclamation, as have large areas of the city-state’s northeastern coast. Many offshore islands have been similarly changed, often through the filling of waters between small islands in order to create cohesive landmasses.

Such development has led to the loss of 95% of Singapore’s mangroves. When Stamford Raffles arrived in Singapore in 1819, the land was largely mangrove swamp; today, mangrove cover comprises less than 0.5% of Singapore’s total land area. , undefinedThis loss has greatly diminished the beneficial effects of mangroves, which include protection against erosion and reduction in organic pollution. Both of these attributes serve to ameliorate coastal water quality.



Singapore has also suffered an enormous loss in coral reefs as the result of extensive land and coastal development. Prior to the land reclamation of the last several decades, Singapore’s coral reefs covered an estimated 100 square kilometers. By 2002, that number had dropped to 54 square kilometers. An estimated relative loss, however, shows that up to a full 60% of the habitat is no longer sustainable. Since coral reef monitoring was first instigated in the late 1980’s, a clear overall decline in live coral cover has been noted, as has a decline in the depths at which corals thrive. Fortunately, though there have been limited extinctions of local species, overall coral reef diversity has not diminished: the main loss has instead been a general, relatively equal decrease in the population abundance of each species. Coral reefs are valued for their work towards carbon sequestration and shore protection (particularly in the dispersal of wave energy), as well as for their contributions to fisheries production,  ecotourism, and scientific research.

Singapore has also seen the negative effects of industrialization impact several other coastal and marine habitats, such as seagrass, seabed, and seashores, all of which have suffered loss or degradation similar to that of the mangroves and coral reefs.

Though much harm has been done to Singapore’s aquatic ecosystems as the result of land reclamation projects and expansive industrialization, there has been more of an effort in recent years to accommodate and restore damaged environments. Since the mid-1990’s, more attention has been paid to Environmental Impact Assessments] (EIA), which identify the potential ecological consequences of a given developmental venture as well as possible solutions to lessen the environmental harm. In the development of the [[Pulau Semakau#Semakau landfill | Semakau Landfill, for example, an extensive EIA was carried out after the project’s commission in 1999. The assessment found that coral reefs and mangroves within the allotted 350-hectare project would be harmed. As such, plans were put in place to reforest the mangroves elsewhere, and sediment screens were installed to prevent silt from reaching reefs that would have otherwise been negatively affected. EIAs are not, however, required by any legislature, and thus are not mandatory for land reclamation projects. Yet, beneficially, the government has been increasingly open to public feedback regarding increased sustainability in future projects for the city-state.

In terms of restoration efforts, nature activists and public authorities alike have been working more and more towards the strengthening of biotic communities. Though Singapore has seen the extinction of more than 28% of native flora and  fauna, the city-state has also witnessed the introduction of foreign flora and fauna to its ecosystems, increasing the country’s  biodiversity. Similar efforts towards the development of nature reserves have helped to protect local wildlife, over half of which is present only in such nature reserves.
