“.. Nuclear Power Revealed

So let me tell you what else they did. They just showed you what's wrong with nuclear power. "Safe to the maximum," they said. "Our devices are strong and cannot fail." But they did. They are no match for Gaia.

It seems that for more than 20 years, every single time we sit in the chair and speak of electric power, we tell you that hundreds of thousands of tons of push/pull energy on a regular schedule is available to you. It is moon-driven, forever. It can make all of the electricity for all of the cities on your planet, no matter how much you use. There's no environmental impact at all. Use the power of the tides, the oceans, the waves in clever ways. Use them in a bigger way than any designer has ever put together yet, to power your cities. The largest cities on your planet are on the coasts, and that's where the power source is. Hydro is the answer. It's not dangerous. You've ignored it because it seems harder to engineer and it's not in a controlled environment. Yet, you've chosen to build one of the most complex and dangerous steam engines on Earth - nuclear power.

We also have indicated that all you have to do is dig down deep enough and the planet will give you heat. It's right below the surface, not too far away all the time. You'll have a Gaia steam engine that way, too. There's no danger at all and you don't have to dig that far. All you have to do is heat fluid, and there are some fluids that boil far faster than water. So we say it again and again. Maybe this will show you what's wrong with what you've been doing, and this will turn the attitudes of your science to create something so beautiful and so powerful for your grandchildren. Why do you think you were given the moon? Now you know.

This benevolent Universe gave you an astral body that allows the waters in your ocean to push and pull and push on the most regular schedule of anything you know of. Yet there you sit enjoying just looking at it instead of using it. It could be enormous, free energy forever, ready to be converted when you design the methods of capturing it. It's time. …”

Micro apartments popular in Amsterdam as house prices rise Housing

DutchNews, March 1, 2023

Amsterdam is leading the way in the sale of micro apartments of between 20 and 50 m2, according to research by the Kadaster land registry

Last year, 1,925 small apartments were sold in the capital and cost an average of just over €400,000, the Kadaster said. That is 1.4 times the price in Utrecht and almost double that of other parts of the country. 

Just over half of the 5,100 small apartments sold last year changed hands in the big four cities and 38% were bought in Amsterdam. 

This is due in part to the capital’s attraction for young adults, who are prepared to live in smaller properties because house prices have risen so much, Kadaster economist Paul de Vries told Dutch News. 

Micro homes are typified by having plenty of shared amenities, such as work space, laundry facilities and cars or bikes.

China axes 15 coal plants abroad after Xi pledge, but loopholes remain: study

Yahoo – AFP, April 22, 2022

cover fossil-fuel investments abroad (AFP/JOHANNES EISELE) (JOHANNES EISELE)
 

More than a dozen Chinese coal power projects overseas were cancelled after a ban last year on funding such plants, but loopholes could allow 18 others to still go ahead, according to a study published Friday. 

China is the world's biggest emitter of the greenhouse gases driving global warming. It has vowed to peak carbon emissions by 2030 and become carbon-neutral by 2060, but these do not include its fossil-fuel investments abroad. 

It is also the largest public funder of overseas coal plants, and was planning to build 67 in more than a dozen countries when President Xi Jinping announced a ban on financing "new projects" in September. 

Since then, Chinese developers have cancelled 15 overseas coal projects as funding dried up and host countries demanded greener alternatives, a study by the Helsinki-based Centre for Research on Energy and Clean Air (CREA) said. 

The cancelled projects would have generated 12.8 gigawatts of electricity -- or the total power generation capacity in Singapore, the think tank added. 

But a lack of clear rules has allowed Chinese developers to continue to build new coal power projects, it warned. 

"The key concern is that China will continue to fund or build new coal projects to power industrial parks under the Belt and Road Initiative," said Isabella Suarez, a researcher at CREA, referring to Xi's $1 trillion global infrastructure push. 

"The loophole is that because the industrial parks have been years in the making, additional coal on these projects would not be considered new, even if... tenders are happening after the pledge to ban coal funding." 

Deadly impact 

China's top economic planner issued vague guidelines in March, telling developers to "proceed cautiously" on coal plants that were in the final stages of planning. 

These could potentially stop Chinese funding for 32 planned coal plants and prompt the "reexamination" of 36 others that are under way, according to the CREA report. 

However, "about 18 coal projects (in the pipeline) that can generate 19.2 Gigawatts of power have already secured financing and permits... and could still go ahead," Suarez said. 

AFP has sought comment on the report from the National Development and Reform Commission, China's economic planner. 

Most of these projects are in Indonesia, where China is investing billions to mine nickel and other minerals needed to build electric vehicles, according to data from the Global Energy Monitor. 

Vietnam and Bangladesh have in recent months requested China to build gas projects instead of the agreed coal projects, according to government notices. 

The deadly impact of climate change -- from extreme heatwaves to more intense superstorms -- is already being felt across the world. 

Experts say emissions must be halved within a decade to limit global warming to well below 2 degrees Celsius (36 degrees Fahrenheit) or ideally to 1.5C as stated in the Paris climate accord.

Montenegro learns true cost of China-backed $1 bn road to nowhere

Yahoo – AFP, Olivera Nikolic, May 27, 2021 

Chinese wprkers have spent six years carving tunnels through solid rock and
raising concrete pillars above gorges and canyons in Montenegro, but the road
in effect goes nowhere


Two sleek new roads vanish into mountain tunnels high above a sleepy Montenegrin village, the unlikely endpoint of a billion-dollar project bankrolled by China that is threatening to derail the tiny country's economy.
 

The government has already burnt through $944 million in Chinese loans to complete the first stretch of road, just 41 kilometres (25 miles), making it among the world's most expensive pieces of tarmac. 

Chinese workers have spent six years carving tunnels through solid rock and raising concrete pillars above gorges and canyons, but the road in effect goes nowhere. 

Almost 130 kilometres still needs to be built at a likely cost of at least one billion euros ($1.2 billion). 

"The construction looks impressive, but we must not stop at this," says 67-year-old Dragan who retired to the village of Matesevo. 

"It's like buying an expensive car and just leaving it parked in the garage." 

Critics question how the rest of the road will be paid for and highlight environmental damage caused by the construction along with corruption allegations over the awarding of work contacts. 

But locals are inclined to talk up the positives. 

"This story has some good sides for us villagers. Some managed to sell their land and leave, which was impossible before," said one villager, whose two-storey home now sits metres from gargantuan concrete pillars propping up the four-lane highway. 

"I manage to sell some vegetables and chickens to the workers," added the man who did not want to be named, reflecting also that dirt mounds from the construction site stop the river from flooding. 

If Montenegro cannot pay its debt to China, it faces arbitration in Beijing and could
be forced to give up control of key infrastructure, according to the contract.

'Big trouble' 

The section linking Matesevo to a town near the capital Podgorica -- the most difficult part to build -- is set to open in November. 

But the road is meant to connect the Adriatic port of Bar in the south with the Serbian border in the north, with the intention that the Serbians will then extend it to their capital, Belgrade. 

It is unclear where the money will come from or how Montenegro -- a country with a GDP of 4.9 billion euros -- will repay its existing debt to China. 

If Montenegro cannot pay, it faces arbitration in Beijing and could be forced to give up control of key infrastructure, according to a copy of the contract seen by AFP. 

China has been widely criticised for saddling small countries with unmanageable debt as part of its global Belt and Road Initiative. 

Critics worry that it will use financial leverage to boost its political power, in what they dub "debt-trap diplomacy". 

But Chinese officials have strenuously denied any ulterior motive to the investment in Montenegro and the wider region. 

"This cooperation is mutually beneficial and win-win," said China's Montenegrin embassy in a statement last month. 

"If someone puts negative labels on China's investment, it is not only unfair to China, but also disrespectful to the countries of the western Balkans." 

With Montenegro's first repayment due in July, it could become the first European country to put those claims to the test. 

"If we do not find sources of funding to build on, then we are in big trouble," Infrastructure Minister Mladen Bojanic told AFP, saying he was committed to finishing the road. 

Critics question how the road will be paid for and highlight environmental damage caused
by the construction along with corruption allegations over the awarding of work contacts.


'Out of public eye'
 

Bojanic is now trying to get help from the European Union to rescue a project he bitterly opposed when he was in opposition, labelling it risky and reckless. 

Risky, reckless and, according to campaigners, corrupt. 

More than one-third of local subcontractors chosen to work on the project had links to the former ruling socialists of President Milo Djukanovic. 

There were no public tenders and the relationship between payments received and the work carried out was not clear, according to anti-corruption watchdog MANS. 

"Decisions on construction were wrongly made out of the public eye, and that is something we will now have to pay for," said the group's Dejan Milovac. 

The government has promised to investigate any corruption claims. 

Further questions have been asked about the environmental impact after the construction work ruined a UNESCO-protected stretch of river near Matesevo, the Chinese firm agreeing to fund work to undo the damage.

Tolls not enough 

Problems with the project were not unforeseen -- experts queued up a decade ago to tell the government that it was not viable. 

They warned that any benefits to commerce and tourism on the Adriatic, or development for poorer northern regions, would never outweigh the costs. 

The current government has admitted revenue from tolls will not even cover the road's annual maintenance, estimated at 77 million euros ($94 million). 

"It would take at least 22-25,000 vehicles a day for the highway to pay off," civil engineer Ivan Kekovic told AFP, roughly four times the number he could envisage on the busiest stretch. 

Even this gloomy assessment may be optimistic if all Montenegrins do their sums like Zeljko Rajkovic, a 55-year-old teacher in Kolasin, close to Matesevo. 

He weighs up the benefits of heading to Podgorica on the new road: 30 minutes travel time rather than 90 minutes on the old road, improved safety. 

Then he considers the downsides: tolls each way, extra fuel consumption. 

"I'll only use the new road if there's a big storm or an emergency," he concludes.

Japan to limit financing of overseas coal power plants

Japan said Thursday it would tighten rules for investment in foreign coal-fired power stations on environmental grounds, but stopped short of ending government funding for projects.

The move comes with the world's third-largest economy under fire for financing projects to build coal plants at home and abroad -- notably in Southeast Asia.

Economy, Trade and Industry Minister Hiroshi Kajiyama told reporters the government "has decided to tighten" the rules for supporting investment.

Countries seeking investment would be required to change their "behaviour" towards decarbonisation, Kajiyama said, but added that the new policy was not about cutting back funding.

"There are developing nations in the world that can only choose coal as an energy source," he said.

Further details were not immediately available.

The government currently provides funding to Japanese companies if their projects meet certain criteria -- such as when a foreign country has no options but to choose coal due to economic reasons.

Major decision

The Global Energy Monitor watchdog said last year that Japan accounted for over US$4.8 billion in financing for coal power plants abroad -- particularly in Indonesia, Vietnam and Bangladesh.

Kimiko Hirata, international director of the environmental NGO Kiko Network, said the new investment decision was a "major decision."

"The coal-fired power stations were the pillar of infrastructure exports for Japan," she told AFP.

But Greenpeace criticised the decision as falling short, saying it showed "no clear policy".

Last week, the government promised to study ways of phasing out older, more polluting coal-fired power stations by 2030, following reports it plans to mothball around 100 ageing plants.

Japan has some 140 coal-fired power stations, providing nearly one-third of the nation's total electricity generation, and second only to LNG-fired plants.

But there are more than a dozen projects underway to build more plants -- despite efforts to phase them out in many other parts of the world.

The appetite for coal-fired plants increased significantly after the Fukushima nuclear power plant accident following the 2011 tsunami.

Japan wants nearly a quarter of its energy needs to be met by renewable sources -- including wind and solar -- by 2030, a figure critics describe as unambitious based on current levels of around 17 percent.

For a rainy day: Amsterdam plans to make new buildings catch rainwater

DutchNews, March 6, 2020 - By Senay Boztas

New build projects in Amsterdam would be forced to capture the first 60mm of rainfall thanks to proposals currently under public consultation. 

The city, which today launches a ‘roadmap’ charting its way to becoming climate neutral, is also concerned about how the built environment absorbs ever-increasing rainfall. 

A proposal, submitted in February, suggests that new builds will be obliged to ‘capture and process rainwater on their own ground, because the climate is changing and in the future ever heavier showers may fall.’ 

The obligation to capture and reuse rainwater – in features such as green roofs, water butts, and ‘grey water’ based sanitary facilities – is intended to help protect streets, cellars, houses and buildings from water damage. 

New builds would be obliged to soak up the first 60mm of rainfall and only then ‘gradually’ release it into city drainage system over 60 hours. 

Daniel Goedbloed, head of the water-management programme Amsterdam Rainproof, said that if the new rules are adopted, they would make a huge difference to the Dutch capital’s capacity to absorb water. 

‘The idea is that all new builds, including those which don’t need to apply for planning permission, can deal with up to 60ml of water on their own plot of land,’ he told DutchNews.nl. ‘You could install a “blue roof” that acts like a temporary lake and then slowly drains water, or a “blue-green” roof with sedum plants and the ability to hold some water. 

Rainwater harvesting systems can also be good, although they need to have water ready for the next use rather than draining it all away.’ 

Costs 

The rule for these systems is that they must catch 90ml of water and drain away 30% of this in 60 hours, he said. Smart rainwater harvesting systems and so-called ‘polder’ roofing would be exempt, and developments which don’t need planning permission would have slightly lower requirements. 

The costs would have to be borne by developers, although it is expected that on its own land, Amsterdam city council would offer a reduced ground rate for developers with rainwater harvesting measures in their plans. 

The public consultation period runs until the end of April and the rain harvesting measure is expected to go to a council vote before the summer. Meanwhile, local rules in areas such as Oud-West already mean that owners can only tile 50% of their gardens in order to let rainwater soak into the ground. 

The attention to rain is part of a drive to future-proof Amsterdam against climate change. The city’s plans to go climate neutral by 2030 – by better insulating homes and removing domestic gas – will reportedly cost ‘billions’ in investment. 

Head of sustainability Marieke van Doorninck on Friday compared the future-proofing plans in Amsterdam to the level of change during the Industrial Revolution, and a report by CE Delft confirmed that the city may be able to reduce its emissions by 48% in 2030, compared with 1990. 

Nika Haspels, a spokeswoman for Amsterdam city council, said that the rainwater proposals fall under this environmental drive. ‘This is part of the climate adaptation strategy,’ she said. ‘We have to do something: if you don’t ensure the rain is captured, then soon you are going to have a problem.’

The Tokyo 2020 Olympic organisers on Wednesday unveiled the "Village Plaza", a key part of the Athletes' Village that is being built from wood donated by municipalities across Japan.

The facility will be a gathering place for athletes and their teams, as well as the site of welcome ceremonies and press briefings during the Games.

The unusual structure is made mostly from wood, with the floors, walls and parts of the roof using timber including larch, Japanese cedar and Japanese cypress.

The vast complex nods to both modern and traditional elements.

novel structures, including an arch frame structure (AFP Photo/Behrouz MEHRI)

"It's based on Japanese traditional wood buildings, but not on any specific building in particular," said Nariki Makihara, Tokyo 2020 senior manager for venues sustainability.

Novel features include columns made by laying wooden planks at inclines against each other, and roof beams made by weaving planks into a latticework.

The wood has been donated by 63 municipalities across the country, and the facility will be dismantled after the Games, with the timber returned for re-use, a model organisers tout as part of their commitment to a sustainable Olympics.

India blows up luxury high-rises over environmental violations

Yahoo – AFP, Abhaya SRIVASTAVA, January 11, 2020

India has seen a construction boom in recent years but developers have often
ridden roughshod over safety and other regulations (AFP Photo/Arun SANKAR)

Two luxury waterfront high-rises in southern India were reduced to rubble in controlled explosions Saturday in a rare example of authorities getting tough on builders who break environmental rules.

The 19-floor H2O Holy Faith complex of 90 flats -- overlooking Kerala state's famous lush backwaters -- was the first to go down, collapsing in just a matter of few seconds.

A thick grey cloud of dust and debris cascaded down after officials detonated explosives drilled into the walls of the building, which had been occupied for several years until the Supreme Court ruled last May that it was constructed in violation of coastal regulations.

Minutes later, the twin towers of Alfa Serene tumbled down with an ear-splitting noise. The remaining two complexes will be razed on Sunday.

A crowd of onlookers who flocked to nearby terraces and roads watched the demolition, after officials in helicopters conducted aerial surveys.

India has seen a construction boom in recent years but developers have often ridden roughshod over safety and other regulations, with the connivance of local officials.

The inhabitants of the apartment blocks in the well-off Maradu district of Kochi city had bought their 343 flats in good faith and now face a lengthy legal fight to recoup their money. Some had invested their life savings.

Sirens went off on Saturday warning people gathered for the demolition to remain at a safe distance while ambulances and fire engines stood on standby.

Ahead of the work, nearby residents told AFP they were worried about the impact of the demolition on their homes.

"When they were demolishing the swimming pool, some of the houses in our neighbourhood developed cracks, we are really worried," said Divya, who has moved into temporary accommodation.

Over 2,000 residents living in the neighbourhood were evacuated as a part of safety measures.

Scenic and fragile

The demolition capped a saga that began in 2006 when a local governing body granted permission to private builders to erect the high-rises.

But last year, the Supreme Court ruled that the builders were in breach of rules about construction in an ecologically sensitive coastal zone, calling it a "colossal loss" to the environment.

"It's a high-tide area and hundreds of illegal structures have come up in the coastal zone," the court ruled as it ordered the buildings razed.

On Friday the court also ordered the demolition of a resort in neighbouring Alappuzha district after its owners lost the appeal of a 2013 ruling that said the structure violated environmental regulations and must be demolished.

Kerala is famed for its brackish lagoons and lakes that run parallel to the Arabian Sea -- creating an environmentally fragile region.

In 2018, the state was battered by its worst floods in almost a century that killed more than 400 people.

Experts blamed the disaster on the government's eagerness to build houses, hotels and resorts with little regard for coastal planning regulations.

The residents of the Maradu apartments initially refused to vacate but moved out after local authorities cut water and power supplies.

They have been given interim partial compensation by the state government while the builders are in the process of providing a refund.

Shamshudeen Karunagapally, who bought a flat for $145,000, said his wife and children did not watch the buildings go down as it was "too painful for them to see their dreams shatter before their eyes".

"We are suffering without any fault," he told AFP.

At least two injured in Jakarta building collapse

Yahoo – AFP, 6 January 2020

A mixed-use building in Jakarta partly collapsed, injuring at least two

A five-storey building in Jakarta partly collapsed Monday morning, injuring at least two people who were taken to hospital, authorities said.

TV images showed about half the building on Jakarta's western side had caved in with concrete and other debris lying on the road. Rescue officials were seen carrying people out on stretchers.

The structure is a mixed residential-commercial space with a convenience store on the ground floor and small rental units on the upper floors.

"The upper floors of the building were empty, while the second floor was a warehouse and a place for employees to rest," West Jakarta police chief Audie Latuheru told reporters.

"The employees ran away when they heard creaking sounds. The two injured people were outside of the building when the accident happened," he added.

Indonesia's national search and rescue agency said three people were injured.

Initial media reports said eight people were wounded, but police later said that figure included those evacuated from the building.

It was not immediately clear what caused the accident or if it was connected to the flooding sparked by torrential rain in the capital region last week that left more than 60 people dead.

The search and rescue agency said it appeared that the downpours may have played a role.

"We found evidence of flooding on the rooftop and the third and fourth floors had no water drainage system," said Budi Purnama, national operations director for Indonesia's search and rescue agency.

on Monday

"Water had seeped through the walls... the structure couldn't hold it any longer."

Police and eyewitness said the accident started shortly after 9:00 am local time (0200 GMT).

"The building just suddenly collapsed," eyewitness Ridwan Ria told AFP.

"There was a thundering noise and it happened very quickly. In seconds the building had collapsed.

"There was no sound or weird noise beforehand," the 60-year-old shop owner added.

Another witness said there was water dripping from the ceiling of the building's shop on Sunday.

"I noticed since yesterday that something was wrong," the witness, identified as Juni, told local TV.

"I went to the store yesterday and saw the place was damp with water dripping from the ceiling."

Police told AFP that another witness, identified as a convenience store employee, said the building had started leaning to one side two years ago.

Lax construction standards have raised widespread concerns about building safety in Indonesia.

In 2018, a group of teenagers practising for a dance and music show were among seven killed when the building they were in collapsed in Cirebon, east of Jakarta.

The same year, at least 75 people were injured when a mezzanine floor at Indonesia's stock exchange building in Jakarta collapsed into the lobby.

Giant construction project takes shape in remote North Korea

undernourished North (AFP Photo/Ed JONES)

Like a scene from an epic film, thousands of workers swarm over the building sites of Samjiyon, a monumental construction project in the far reaches of North Korea ordered by leader Kim Jong Un.

They clamber over wooden scaffolding and dangle from window frames, and whether they are carrying loads, sifting sand or mixing concrete, most of the work is carried out by hand.

The plan involves nothing less than the rebuilding of the entire town of Samjiyon, the seat of a county that includes the supposed birthplace of Kim's father and predecessor Kim Jong Il, and Mount Paektu, the spiritual birthplace of the Korean nation.

It encompasses a museum of revolutionary activities, a winter sports training complex, processing plants for blueberries and potatoes -- two of the area's most important crops -- a new railway line to Hyesan, and 10,000 apartments.

It is the kind of showpiece scheme that can only be launched by a state as monolithic as North Korea, where authorities can decide to deploy vast amounts of resources and manpower to a single goal and implement it by order.

The results can be striking -- thousands of houses were built in just three months after flooding hit North Hamgyong province in 2016.

But doubts have been raised about the sustainability of such projects once the physical infrastructure is established, with questions over issues ranging from utility supplies to durability and economic viability.

'Home of our revolution'

Leader Kim has himself addressed such concerns on his several inspection visits to Samjiyon -- one of which, last year, saw him photographed sitting with officials on a mountain of potatoes, which he is encouraging to diversify the food sources in the chronically undernourished North.

The builders should prioritise quality over speed, he told them at the time, with the official Korean Central News Agency (KCNA) citing him saying that if construction was "gorgeous in appearance but poor in substance, it will be blamed by the people and future generations".

He has also stressed the need to ensure sufficient electricity supplies in the drive to turn Samjiyon, the "home of our revolution" into "a highly civilised mountainous city" and "the richest county in the country", according to KCNA.

undernourished North (AFP Photo/Ed JONES)

It is an ambitious goal in a remote, challenging environment, with long, bitterly cold winters and mountainous terrain, and an area where many roads are still unsealed.

According to local officials, around half of the workforce in Samjiyon county -- which has a population of 25,000 -- are employed in maintaining its historic sites and related activities, 20 percent in agriculture and the rest in industry, including food processing.

'Hostile forces'

Pyongyang has given no figures for the cost of the redevelopment, which will open in phases with Kim ordering completion by the 75th anniversary of the foundation of the ruling Workers' Party of Korea in October next year.

The project includes plans to build 10,000 apartments (AFP Photo/Ed JONES)

Some of the Samjiyon buildings already appear finished with their exteriors tiled, others remain just concrete shells.

Many of the builders are soldiers -- much of the North's army is devoted to construction -- while others are civilians, and they work even on the harvest holiday of Chusok, one of Korea's most important traditional festivals.

Students have been sent to work on the scheme during university holidays and some of those on site appear to be teenagers.

But while the North is never short of manpower, observers suggest that sanctions imposed on Pyongyang over its nuclear and ballistic missile programmes have impacted projects such as Samjiyon and the giant Wonsan-Kalma tourist development -- which has repeatedly been delayed -- on the west coast.

KCNA quoted Kim in April calling Samjiyon "a fierce class and political struggle against the hostile forces seeking to check the advance of the DPRK".

What lies beneath: Singapore plans a subterranean future

Yahoo – AFP, Martin Abbugao, September 1, 2019

Singapore has already built an underground highway and state-of-the-art air
conditioning system, but is now looking to house more facilities beneath
the surface in order to optimise land use above it (AFP Photo/Roslan RAHMAN)

Singapore (AFP) - Space-starved Singapore has expanded outwards by building into the sea and upwards by constructing high-rises but planners are now looking underground as they seek new areas for growth.

The nation has carefully managed its rapid growth in recent decades to avoid the problems faced by other fast developing Asian metropolises, such as overcrowding and traffic chaos.

But with its population of 5.6 million expected to grow steadily in coming years, authorities are now considering how to better use the space below the streets in a city that is just half the size of Los Angeles.

Singapore has already built an underground highway and state-of-the-art air conditioning system, but is now looking to house more facilities beneath the surface in order to optimise land use above it.

"We need to consider options for putting critical infrastructure underground," Abhineet Kaul, a Singapore-based public sector specialist at consultancy Frost & Sullivan, told AFP.

"We have an increasing need for industrial, commercial, residential and green space on land in Singapore."

say (AFP Photo/Roslan RAHMAN)

According to a draft development plan released in March, authorities want to put utilities, transport as well as storage and industrial facilities underground in order to free up land on the surface.

There are as yet no plans to put housing underground, however.

Three-dimensional technology will be used to produce subterranean maps, with three pilot areas targeted initially, according to the Urban Redevelopment Authority, which created the development plan.

Digging deep

Singapore is the latest city to try to make use of subterranean space.

Finland's capital Helsinki has tunnels housing car parks, shopping malls and even swimming pools, while Montreal in Canada has a so-called "Underground City", a tunnel network connecting key points.

In a report commissioned by Samsung about what the world will look like in 50 years, experts predicted the appearance of "earthscrapers" -- like an inverted skyscraper burrowing downwards for many storeys -- in an attempt to save space in overcrowded cities.

Singapore's main method of expansion has been land reclamation from the sea, which has increased the country's area by over a quarter to 720 square kilometres (280 square miles), with most growth happening since independence in 1965.

But reclamation has become more expensive as it moved to deeper waters, while countries that used to sell sand to Singapore have stopped exports due to environmental concerns.

Unregulated sand mining erodes beaches and riverbanks, affecting wildlife and removing natural barriers to flooding, and dredging the seabed can damage ecosystems, green groups say.

Moving facilities underground has advantages beyond saving space, including reduced use of air conditioning which could save energy in Singapore's tropical climate.

Still, building underground in Singapore poses challenges -- construction is difficult beneath an already urbanised environment while new projects will compete for space with existing subterranean facilities.

"Underground construction normally involves the blasting of rocks and if it's in the downtown area, you will not be able to use blasting," said Chu Jian, a civil and environmental engineering professor at the Nanyang Technological University (NTU).

'Next frontier'

One of the most ambitious underground projects so far in Singapore is a system that pumps chilled water through pipes to cool buildings around the city-state's popular waterfront district of Marina Bay.

Buildings which use the centralised system -- rather than relying entirely on their own air conditioners -- have reduced energy consumption by around 40 percent, said Foo Yang Kwang, chief engineer of Singapore District Cooling, SP Group, which is behind the project.

Reduced energy use has enabled the buildings to slash their annual carbon dioxide emissions by 34,500 tonnes, which is equivalent to taking 10,000 cars off the road, he said.

Other current subterranean facilities in Singapore include Southeast Asia's longest underground expressway, measuring 12 kilometres (7.4 miles), the metro train, an ammunitions depot, and rock caverns beneath the seabed which are used to store oil.

NTU, one of the city's top institutes of higher education, is considering building labs and even classrooms underground, according to Chu.

But he said shifting things underground is just one way of coping as the city-state grows: "It is the next frontier, but not the final frontier.

"I am confident that we will be able to figure out other ways to create new space."
