EspañolLAND RECLAMATION
(Redirected from Reclaimed land)
'Land reclamation' is either of two distinct practices. One involves creating new land from sea- or riverbeds, the other refers to restoring an area to a more natural state (such as after pollution or salination have made it unusable).
'Land reclamation' is the creation of new land where there was once water. Notable examples include parts of New Orleans; Washington, D.C. (which is partially built on land that was once swamp); Helsinki (of which the major part of the city center is built on reclaimed land); the Cape Town foreshore; the Chicago shoreline, the Manila Bay shoreline, Back Bay, Boston, Massachusetts; Battery Park City, Manhattan; the port of Zeebrugge Belgium and the polders of the Netherlands.
Japan, the southern Chinese cities of Hong Kong and Macau and the city-state of Singapore, where land is in short supply, are also famous for their efforts on land reclamation. One of the earliest and famous project was the Praya Reclamation Scheme, which added 50 to 60 acres of land in 1890 during the second phase of construction. It was one of the most ambitious project ever taken during the Colonial Hong Kong era.[1] Some 20% of land in the Tokyo Bay area has been reclaimed[2]. Monaco and the British territory of Gibraltar are also expanding due to land reclamation. The city of Rio de Janeiro was largely built on reclaimed land.
Artificial islands are an example of land reclamation. Creating an artificial island is an expensive and risky undertaking. It is often considered in places that are densely populated and flat land is scarce. 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.
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 productive use of land that would otherwise be restricted to wildlife habitat. It is also an important method of mosquito control.

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.
'Land reclamation' or 'Land rehabilitation' is also the process of cleaning up a site that has sustained environmental degradation, such as strip mining. This can be done to allow for some form of human use (such as a housing development) or to restore that area back to its natural state as a wildlife habitat home.
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.
Hong Kong legislators passed the Protection of the Harbour Ordinance in 1996 in an effort to safeguard the increasingly threatened Victoria Harbour against encroaching land development[3].

Creating new land
