Land reclamation
Land reclamation, usually known as reclamation, and also known as land fill (not to be confused with a waste landfill), is the process of creating new land from oceans, seas, riverbeds or lake beds. The land reclaimed is known as reclamation ground, reclaimed land, or land fill.
In some jurisdictions, including parts of the United States,<ref>"American Society for Mining and Reclamation". Archived from the original on 2012-03-23. Retrieved 2012-04-01.</ref> the term "reclamation" can refer to returning disturbed lands to an improved state. In Alberta, Canada, for example, reclamation is defined by the provincial government as "The process of reconverting disturbed land to its former or other productive uses."<ref>Powter, Chris (2002).

History
One of the earliest large-scale projects was the Beemster Polder in the Netherlands, realized in 1612 adding 70 square kilometres (27 sq mi) of land. In Hong Kong the Praya Reclamation Scheme added 20 to 24 hectares (50 to 60 acres) of land in 1890 during the second phase of construction. It was one of the most ambitious projects ever taken during the Colonial Hong Kong era.<ref name="Bard">Bard, Solomon. [2002] (2002). Voices from the Past: Hong Kong 1842–1918. HK University press.

The city of Rio de Janeiro was largely built on reclaimed land, as was Wellington, New Zealand.
Methods
Land reclamation can be achieved by a number of different methods. The simplest method involves filling the area with large amounts of heavy rock and/or cement, then filling with clay and dirt until the desired height is reached. The process is called "infilling"<ref>Lambi, Cornelius Mbifung (2001). Environmental issues: problems and prospects. Bamenda, Cameroon: Unique Printers. p. 152. ISBN 978-9956-11-005-6.</ref> and the material used to fill the space is generally called "infill".<ref>"Wisconsin Supplement Engineering Field Handbook Chapter 16: Streambank and Shoreline Protection" (PDF).

Deep cement mixing is used typically in situations in which the material displaced by either dredging or draining may be contaminated and hence needs to be contained. Land dredging is also another method of land reclamation. It is the removal of sediments and debris from the bottom of a body of water. It is commonly used for maintaining reclaimed land masses as sedimentation, a natural process, fills channels and harbors.<ref>Administration, US Department of Commerce, National Oceanic and Atmospheric.

Agriculture
Agriculture was a driver of land reclamation before industrialisation.<ref>Curtis, Daniel R. (2014). "Into the frontier: medieval land reclamation and the creation of new societies. Comparing Holland and the Po Valley, 800–1500". Journal of Historical Geography. Academia.edu. 44: 93–108. doi:10.1016/j.jhg.2013.10.004.</ref> In South China, farmers reclaimed paddy fields by enclosing an area with a stone wall on the sea shore near a river mouth or river delta. The species of rice that are grown on these grounds are more salt tolerant. Another use of such enclosed land is the creation of fish ponds. It is commonly seen on the Pearl River Delta and Hong Kong. These reclaimed areas also attract species of migrating birds.
A related practice is the draining of swampy or seasonally submerged wetlands to convert them to farmland. While this does not create new land exactly, it allows commercially productive use of land that would otherwise be restricted to wildlife habitat. It is also an important method of mosquito control.
Even in the post-industrial age, there have been land reclamation projects intended for increasing available agricultural land. For example, the village of Ogata in Akita, Japan, was established on land reclaimed from Lake Hachirōgata (Japan's second largest lake at the time) starting in 1957. By 1977, the amount of land reclaimed totalled 172.03 square kilometres (66.42 sq mi).<ref>"The History of Ogata-Mura". Ogata-Mura. 2008. Archived from the original on 2015-09-24.</ref>
Artificial islands
Artificial islands are an example of land reclamation. Creating an artificial island is an expensive and risky undertaking. It is often considered in places with high population density and a scarcity of flat land. Kansai International Airport (in Osaka) and Hong Kong International Airport are examples where this process was deemed necessary. The Palm Islands, The World and hotel Burj al-Arab off Dubai in the United Arab Emirates are other examples of artificial islands (although there is yet no real "scarcity of land" in Dubai), as well as the Flevopolder in the Netherlands which is the largest artificial island in the world.
Beach restoration
Beach rebuilding is the process of repairing beaches using materials such as sand or mud from inland. This can be used to build up beaches suffering from beach starvation or erosion from longshore drift. It stops the movement of the original beach material through longshore drift and retains a natural look to the beach. Although it is not a long-lasting solution, it is cheap compared to other types of coastal defences. An example of this is the city of Mumbai.<ref name="Mumbai"/>
Landfill
As human overcrowding of developed areas intensified during the 20th century, it has become important to develop land re-use strategies for completed landfills. Some of the most common usages are for parks, golf courses and other sports fields. Increasingly, however, office buildings and industrial uses are made on a completed landfill. In these latter uses, methane capture is customarily carried out to minimize explosive hazard within the building.
An example of a Class A office building constructed over a landfill is the Dakin Building at Sierra Point, Brisbane, California. The underlying fill was deposited from 1965 to 1985, mostly consisting of construction debris from San Francisco and some municipal wastes. Aerial photographs prior to 1965 show this area to be tidelands of the San Francisco Bay. A clay cap was constructed over the debris prior to building approval.<ref>Paul B. Awosika and Marc Papineau, Phase One Environmental Site Assessment, 7000 Marina Boulevard, Brisbane, California, prepared for Argentum International by Certified. Engineering & Testing Company, Boston, Massachusetts, July 15, 1993</ref>
A notable example is Sydney Olympic Park, the primary venue for the 2000 Summer Olympic Games, which was built atop an industrial wasteland that included landfills.
Another strategy for landfill is the incineration of landfill trash at high temperature via the plasma-arc gasification process, which is currently used at two facilities in Japan, and will be used at a planned facility in St. Lucie County, Florida.<ref>"Florida county plans to vaporize landfill trash".

Environmental impact
Draining wetlands for ploughing, for example, is a form of habitat destruction. In some parts of the world, new reclamation projects are restricted or no longer allowed, due to environmental protection laws. Reclamation projects have strong negative impacts on coastal populations, although some species can take advantage of the newly created area.<ref>Borzée, Amaël; Kim, Kyungmin; Heo, Kyongman; Jablonski, Piotr G.; Jang, Yikweon (4 October 2017).

Environmental legislation
The State of California created a state commission, the San Francisco Bay Conservation and Development Commission, in 1965 to protect San Francisco Bay and regulate development near its shores. The commission was created in response to growing concern over the shrinking size of the bay.
Hong Kong legislators passed the Protection of the Harbour Ordinance, proposed by the Society for Protection of the Harbour, in 1997 in an effort to safeguard the increasingly threatened Victoria Harbour against encroaching land development.<ref name="bill">Wallis, Keith (February 12, 1996). "Bill seeks to protect harbour". Hong Kong Standard. Archived from the original on June 4, 2011. Retrieved 2007-03-23.</ref> Several large reclamation schemes at Green Island, West Kowloon, and Kowloon Bay were subsequently shelved, and others reduced in size.
Dangers
Reclaimed land is highly susceptible to soil liquefaction during earthquakes,<ref name=abag>"The REAL Dirt on Liquefaction" (PDF). ASSOCIATION OF SAN FRANCISCO BAY AREA GOVERNMENTS. February 2001. Archived from the original (PDF) on 2012-07-23.</ref> which can amplify the amount of damage that occurs to buildings and infrastructure. Subsidence is another issue, both from soil compaction on filled land, and also when wetlands are enclosed by levees and drained to create Polders. Drained marshes will eventually sink below the surrounding water level, increasing the danger from flooding.

In the 1980s, North Korea commenced a "find new land" program to reclaim 300,000 hectares of land (3,000 km2 or 1,160 mi2) in order to expand the country's supply of arable land. The project was unsuccessful and only reclaimed 20,000 hectares (200 km2 or 70 mi2) by the time it was cancelled after the death of Kim Il-sung in 1994. It also contributed to the collapse of the North Korean economy and the subsequent famine in the 1990s. Land reclamation efforts resumed in the 2010s under Kim Jong-un with more success. North Korea constructed artificial islands in the Yellow Sea containing Korean People's Army bases, possibly inspired by Chinese artificial islands in the South China Sea and possibly as bases for long-range ballistic missiles.<ref>Cha, Victor D.
