Land reclamation has been happening for centuries in low-lying countries like the Netherlands, where around 17% of the country’s current land has been reclaimed from the sea or lakes. Massive-scale land reclamation projects are a more recent phenomenon and have proved popular in places that have plenty of coast but not enough mainland to suit their needs.
These projects can create land where once there was sea for all sorts of uses, from creating super-modern housing developments to an entertainment archipelago full of hotels, restaurants, theatres and shops. Here are seven examples of the good, the bad and the ugly of global land reclamation.
The Palm Jumeirah, Dubai
The Palm is the world’s most instantly recognisable land reclamation site, shaped like a giant palm tree stretching out into the Persian Gulf. Surrounded by an 11km breakwater, it’s visible from space and comes complete with its own monorail to get you around the man-made archipelago. Don’t expect to find affordable housing on the Palm though – it is a millionaire’s playground.
Nearby, an even bigger land reclamation project called The World is designed like a map of the earth, with individual islands representing each country. Dredging work began in 2003 and while construction stalled during the global financial crash of 2008, many of the islands are now privately owned.
Result: Palm Jumeirah is one of the Middle East’s most popular tourist destinations, thanks to its unique design.
Cable Car at Ngong Ping, Hong Kong
Hong Kong is one of the most densely populated countries in the world and needs more space to house its growing population. Lantau Tomorrow Vision is a huge land reclamation project that’s going to create artificial islands off the coast of Lantau Island.
The incredibly high cost of the project (HK$624bn) has attracted criticism, with 40% of Hong Kong residents against the plans, despite Hong Kong CEO Carrie Lam claiming it could provide up to 1.1m new homes. The High Court in Hong Kong recently rejected a local journalist’s application for a judicial review of the project.
Result: Lantau Tomorrow Vision is a long way from being finished: the first set of residents won’t be moving in until 2034.
Resident walks near the sea wall in Jakarta, Indonesia
Jakarta, the fastest sinking city in the world, made a plan in 2014 to tackle rising sea levels and subsidence. It was called The Great Garuda (named after the shape of the mythical bird on Indonesia’s coat of arms) and meant creating 17 artificial islands off the island’s north coast. Consultants on the project hailed it as the only alternative to abandoning north Jakarta to the flood waters entirely.
Four of the islands were created, but work has been halted because of opposition to the project. That opposition included fishing communities, whose income was drastically reduced by the pollution created by the land reclamation work. In 2017, Jakarta elected a new governor and permission to create the remaining 13 islands was revoked the following year.
Result: Work on The Great Garuda has halted for now. A smaller project, called NCICD II is currently under way, focusing purely on flood defence (rather than combining it with housing).

Eko Atlantic City includes residential, commercial and financial properties in a project combining coastal protection and city expansion. Eventually providing housing for 250,000 people, it has an 8.5km-long sea wall, dubbed the Great Wall of Lagos, to protect Nigeria’s capital from coastal erosion and rising sea levels.
However, the land reclamation has created a change in the water flows, leading to greater erosion in some surrounding areas, says Emeka Eleh FRICS, a partner in Ubosi Eleh & Co, an estate surveyor and valuer in Nigeria. And environmental groups say dredging from the nearby ocean floor has left local residents more vulnerable to storm surges.
Result: Construction on the newly-formed land is well under way, with the 33-story Eko Pearl Towers one of the first to be completed in 2020.

Marina Bay, Sinagpore
Land reclamation work to create valuable waterfront real estate in Singapore began in 1969 and was completed in the 2000s. The Marina Bay area is incredibly popular with residents and visitors and is where you’ll find the famous triple-towered Marina Bay Sands – a massive resort and conference centre, as well as the durian-shaped Esplanade Theatre.
Result: Marina Bay has become one of the country’s top destinations for restaurants, hotels and attractions.

Much of the Netherlands is below sea level, meaning coastal protection and flood prevention measures are high on the national agenda. Katwijk is a coastal beach resort about half an hour north-east of The Hague that was at risk of being washed away, with a flood wall that was too low and a town that had expanded beyond the defences.
In 2015, Katwijk took advantage of the Netherland’s national flood relief fund to construct a 1km-long dune that slopes gradually out to sea over several hundred metres. Construction involved no deep dredging and the resulting dune incorporated a car park with 663 spaces.
Result: Another success story on the Dutch coastline. The dune blends in with the local landscape and contains areas of vegetation for wildlife.

Land reclamation of Gurney Wharf, Penang, Malaysia
Penang, on the north-west coast of Malaysia, plans to create three new islands. Danish architect firm Bjarke Ingels Group envisioned a futuristic design focused on biodiversity and dubbed it BiodiverCity.
Like Indonesia’s Great Garuda, critics worry it doesn’t go far enough to protect fish stocks. Fishermen have rejected the compensation offered by the government of RM20,000 (£3,406), as well as the Environmental Impact Assessment report on the project.
Malaysian authorities say the development is going to be socially and economically inclusive and have suggested that a quarter of new homes created could be in the affordable housing price bracket of around RM350,000 (£60,000).
Result: It looks set to be politically contentious and there are environmental concerns still to be addressed, but it’s going ahead.
