China’s urban policy unit just met for the first time in 38 years. Here’s what it recommended

On 21 February, when China’s State Council released a new set of urban development guidelines, it backtracked on many of the conventions that have defined the past two decades of rampant urbanisation. These new guidelines aim to produce a framework which will revamp and revitalise China’s cities – to create urban areas that have improved navigability, tighter-knit communities, better access to commercial and public areas, and are less resource intensive.

These new directives were taken from the recommendations derived from a rare meeting of the Central Urban Work Conference this past December – the last time it met was in 1978 – and come down from the top echelons of power in the country. They are, to put it bluntly, an enormous milestone that should have a drastic impact on how China’s cities develop into the future.

Over the past couple of decades China has been undergoing an unprecedented urbanisation boom. Cities across the country have been building hundreds of completely new sub-cities, districts, and towns, as China’s urban population jumped from under 20 percent in 1978, to 57 percent today.


The breakneck speed of urbanisation during this era often outpaced quality planning, and China gradually became a land of single-use, car-dependent, Soviet-style superblocks. This has resulted in a uniform urban landscape across the country – “a thousand cities with the same face,” as it is often put. Environmentally speaking, these water-heavy, land-intensive, and car-dependent sprawling new urban areas were horrendous. What’s more, over a million villages, myriad historic areas, ancient landmarks, and traditional-style urban neighborhoods have been razed in the pursuit of new land for building these new developments.

But for some time now there has been a budding consciousness among some urban designers, architects, and government officials that China’s brand of urbanisation was far from optimal — socially, economically, and environmentally — and that the country must build its cities differently. To this end, the central government stepped in to deliver this new set of urban development guidelines, which aim to apply principles of sustainable urban development to all cities across China.

"These new standards are an urban design revolution,” says Peter Calthorpe, a principal at Calthorpe Associates, an architecture firm that has been working to improve China’s urban areas. “They overturn the destructive Chinese model of superblocks, gated communities, and giant streets that has been too long eroding the livability their cities. [The authorities] have been testing these ideas for years, but now they are moving them to a scale that is unprecedented.”

These new guidelines support many urban design strategies that have been developed successfully in cities around the world, such as in New York, London, and Copenhagen. More specifically, these guidelines bring the following seven areas into focus:

1. Denser street networks

At the root of these urbanisation guidelines is a revamping of the street layout in urban areas – to improve the transportation network, increase walkability, create space for more street-facing shops, and enhance the social fabric of urban neighbourhoods. This process will be partially carried out by breaking up superblocks with narrower, one-way streets, as well as opening up and phasing out gated communities.

This last move which has been highly controversial in China. “For the discussion right now about the gated community, I really think that it should not be about how to take the walls down, which we have heard so much about recently,” said Wen Zhao, an associate partner at ZGF, a design firm that has been experimenting with open neighborhoods in China since 2006. “I rather see this as a new urban design movement focusing on how to create a new type of open neighborhood that work with the local lifestyle and culture.”

2. Enforcing urban growth boundaries

Over the past couple of decades China’s cities have been swallowing up large tracts of countryside as they grow to many times their former sizes. At the height of the urbanisation boom, over 2,000 km2 of rural land was being requisitioned annually for new city building.

The sheer size and scale of many of these urban expansion projects is almost inconceivable: Shanghai increased its area sevenfold in 15 years; Dantu, a new area of Zhenjiang, is 748 km2 (about half the size of Greater London). Chenggong in Kunming is 461 km2; Tianjin’s Binhai New Area comes in at 2,270 km2; and Changzhou, in Jiangsu province, has one new district the size of Los Angeles and is working on absorbing another which is larger than London.

Despite having large populations, this rapid expansion means that many Chinese cities are less dense than they could – and, some say, should – be. Under the directives of these new guidelines, growth boundaries will be instituted to curb urban expansion. This is intended to preserve land for agriculture and to promote more sustainable, less resource-intensive, compact development.

3. Expanding mixed-use development

The new urbanisation guidelines encourage mixed-use development and recommend that all residents should have improved access to a diverse range of public and commercial amenities – schools, supermarkets, retirement centers, hospitals, parks, and cultural centers – within range of where they live. There is a special emphasis on green space: the guidelines decree that all city dwellers should have access to public parks, gardens, and other open areas.

“To build a healthy living environment, we have to actively create a new zoning guideline,” said Wen Zhao. “The current functional zone approach, like sports zone, medical zone, etc., in many cities is not the best solution for increasing the performance of the city or communities. I believe that the concept of mixed-use is the better solution.”

One article from a user with the handle “Pretending to be New York” on China’s popular WeChat compares New York City with Beijing. “The convenience of Manhattan is difficult to imagine without experiencing it first-hand. Within two minutes of my apartment, I can reach the metro, Starbucks, supermarkets, movie theaters, office supply store, gym, furniture store, bookstore, library – anything you can think of.

“This megacity has the same conveniences as a small city in China. When you compare Manhattan to Beijing, where it can take 10 minutes to cross a road because you have to take a pedestrian bridge or walk underground, Manhattan really seems like heaven, and is truly a city built for people.”

4. Increasing the prevalence of public transportation

The new guidelines also emphasise the need for a diverse mix of public transportation options, including light rail, buses, and subways.

Although China already has a relatively effective bus system, and is working to build over 7,000km of new subway lines in cities across the country by 2020, the new guidelines call for enhancing these networks even further to ensure everyone within an urban center is always within 500m of public transportation.

5. Historical preservation and city character

The calamity of China having so many cities that look virtually identical, and the wholesale destruction of historic areas, has not gone unnoticed. To salvage what is left of the country’s architectural legacy – and to encourage more diverse styles of building – these guidelines include an entire section about the cultivation of what they dub “city character.”

In practice this means preserving historic architecture, retrofitting old buildings, revitalising older urban areas, and enhancing “cultural continuity” by reviving the long and unique histories of each city.

6. Improve urban architecture quality and construction methods

It has often been stated that the average modern building in China has an expected lifespan of 25-30 years - far less than the 74 years of U.S. buildings and the 132 years of those in the UK. There are many reasons for this: poor design, lack of maintenance, and the use of shoddy building materials.

So this is another woe the new guidelines will attempt to remedy. The guidelines also mandate more efficient and environmentally beneficial building techniques; construction waste and pollution will be cut, building times will be shortened, and within 10 years 30 percent of all buildings constructed will be pre-fabricated.

7. Expand energy efficiency and environmental quality in cities

Over the past decade China has been experimenting with less environmentally pernicious forms of urbanisation – with varying results.

These new guidelines have taken green building and urban planning to a new height by decreeing that government buildings have energy-efficient lighting and other low-carbon technologies; that new buildings must have meters for heating; that water-efficient “sponge city” development should be expanded; that natural environments in urban areas be revitalised, and that air and water quality be restored.

According to these new mandates, by 2020 all cities from the prefecture-level up should treat 100 percent of their wastewater, and water-scarce cities should reuse 20 percent of their water. The guidelines also outline that, by 2020, waste re-use should top 35 percent across the country.

Conclusion

In general, these guidelines are intended to repair the mistakes wrought during China’s recent era of rampant urbanisation – and to set a more environmentally, socially, and economically sound course for urban development in the future.

China’s development will no longer revolve around the profit-centered mindset of building anew as fast as possible. Instead it will focus on improving and re-vitalising what’s already there. It’ll turn the country’s cities away from their dystopian trajectory, and into socially dynamic, community oriented, healthy, convenient, and sustainable places to live and work.

This fun map allows you to see what a nuclear detonation would do to any city on Earth

In 1984, the BBC broadcast Threads, a documentary-style drama in which a young Sheffield couple rush to get married because of an unplanned pregnancy, but never quite get round to it because half way through the film the Soviets drop a nuclear bomb on Sheffield. Jimmy, we assume, is killed in the blast (he just disappears, never to be seen again); Ruth survives, but dies of old age 10 years later, while still in her early 30s, leaving her daughter to find for herself in a post-apocalyptic wasteland.

It’s horrifying. It’s so horrifying I’ve never seen the whole thing, even though it’s an incredibly good film which is freely available online, because I once watched the 10 minutes from the middle of the film which show the bomb actually going off and it genuinely gave me nightmares for a month.

In my mind, I suppose, I’d always imagined that being nuked would be a reasonably clean way to go – a bright light, a rushing noise and then whatever happened next wasn’t your problem. Threads taught me that maybe I had a rose-tinted view of nuclear holocaust.

Anyway. In the event you’d like to check what a nuke would do to the real Sheffield, the helpful NukeMap website has the answer.

It shows that dropping a bomb of the same size as the one the US used on Hiroshima in 1945 – a relatively diddly 15kt – would probably kill around 76,500 people:

Those within the central yellow and red circles would be likely to die instantly, due to fireball or air pressure. In the green circle, the radiation would kill at least half the population over a period of hours, days or weeks. In the grey, the thing most likely to kill you would be the collapse of your house, thanks to the air blast, while those in the outer, orange circle would most likely to get away with third degree burns.

Other than that, it’d be quite a nice day.

“Little boy”, the bomb dropped on Hiroshima, was tiny, by the standards of the bombs out there in the world today, of course – but don’t worry, because NukeMap lets you try bigger bombs on for size, too.

The largest bomb in the US arsenal at present is the B-83 which, weighing in at 1.2Mt, is about 80 times the size of Little Boy. Detonate that, and the map has to zoom out, quite a lot.

That’s an estimated 303,000 dead, around a quarter of the population of South Yorkshire. Another 400,000 are injured.

The biggest bomb of all in this fictional arsenal is the USSRS’s 100Mt Tsar Bomba, which was designed but never tested. (The smaller 50MT variety was tested in 1951.) Here’s what that would do:

Around 1.5m dead; 4.7m injured. Bloody hell.

We don’t have to stick to Sheffield, of course. Here’s what the same bomb would do to London:

(Near universal fatalities in zones 1 & 2. Widespread death as far as St Albans and Sevenoaks. Third degree burns in Brighton and Milton Keynes. Over 5.9m dead; another 6m injured.)

Everyone in this orange circle is definitely dead.

Or New York:

(More than 8m dead; another 6.7m injured. Fatalities effectively universal in Lower Manhattan, Downtown Brooklyn, Williamsburg, and Hoboken.)

Or, since it’s the biggest city in the world, Tokyo:

(Nearly 14m dead. Another 14.5m injured. By way of comparison, the estimated death toll of the Hiroshima bombing was somewhere between 90,000 and 146,000.)

I’m going to stop there. But if you’re feeling morbid, you can drop a bomb of any size on any area of earth, just to see what happens.


And whatever you do though: do not watch Threads. Just trust me on this.
