Britain’s housing crisis: are garden cities the answer?

"They’re billed as an idyllic alternative to generic commuter towns. But the first of a new generation of garden cities, in Ebbsfleet, Kent, has run into controversy. Will the end result be bog-standard suburban housing blighting the green belt?

Beyond the shops – a Co-op, a cafe, a tattoo studio called Demon Inkorporation – are narrow terraced streets where doors open on to the pavement. A newer red-brick estate has been erected on an old slurry pit, and in the distance are wind turbines, pylons, the roar of the A2 and the surreal sight of container ships the size of tower blocks slipping down the Thames.
Welcome to Britain’s newest garden city. Ebbsfleet, the name of the high-speed Eurostar railway station squeezed on to waste ground between Dartford and Gravesend, is the first of the government’s new generation of garden cities: low-density communities with generous green spaces and good local facilities. Garden cities are an idea whose time has come (again), enjoying the support of George Osborne, Ed Miliband and Nick Clegg. They are seen as a way to persuade not-in-my-backyarders to tolerate urgently needed new housing estates. Are garden cities the solution to Britain’s housing crisis? Or are they a sham – the same-old suburbs smothering precious green belt?
This debate was ignited by David Rudlin, an urban designer who last month won the £250,000 Wolfson Economics prize for arguing we must “take a confident bite out of the green belt” and build new garden city extensions to around 40 existing provincial cities and towns, including Oxford, Taunton, Ipswich and Carlisle.
Politicians, architects and planners all say that the housing crisis – which means all but the seriously rich are priced out of booming cities and all but the super-rich are priced out of London – is only going to get worse: demographic trends suggest that 6m new homes are required over the next 30 years. That means 200,000 each year, and in England we have struggled to build half that – just 112,630 new homes – in the 12 months to March 2014.
Garden cities were the vision of a shorthand typist called Ebenezer Howard who worked in parliament and, in 1898, outlined his utopian alternative to industrial slums, combining the best of town and country. Howard’s vision of self-sufficient local communities of affordable homes built at a low density with green spaces and jobs nearby was realised through first Letchworth and then Welwyn Garden City. Letchworth offered affordable renting and home ownership (a three-bedroom house cost £175 in 1906), leisure facilities such as a nine-hole golf course and innovations including Britain’s first roundabout. Lenin is rumoured to have stayed the night in the town in 1907 and the garden city ideals were exported abroad, to Soviet cities including Stalingrad, and other new cities such as Canberra, Australia.

Letchworth and Welwyn Garden City’s generous public spaces and green, low-density avenues are still so popular that Lord Wolfson, the funder of the Wolfson prize and a generous Tory donor, believes they could solve the conundrum of how to construct thousands of new homes without alienating greenbelt-loving locals. But the idea of building on green belt – as advocated by Rudlin – is still toxic to top Tories: it has been sharply dismissed by the Conservatives’ housing minister and also criticised by the architect Lord Rogers, a champion of urban renewal through brownfield development. George Osborne, the chancellor, has stuck to Tory-friendly territory by earmarking brownfield land around Ebbsfleet for the first of the new garden cities. Nick Clegg, the deputy prime minister,has invited local authorities to bid for funding of up to £2.4bn for three more.
The desolate picture glimpsed from a high-speed train rushing through Ebbsfleet might confirm sceptics’ suspicions that garden cities are a hollow rebranding exercise. “To call this a garden city is satire,” wrote Simon Jenkins earlier this year. But a closer look at the new – and old – communities in this part of Kent reveals a more complicated picture.
Ebbsfleet is promising on paper. There is probably no better place to build a sizeable new town in south-east England. It has an underused high-speed railway station. A canyon-sized disused quarry already has outline planning permission for 10,000 new homes; more have been approved on adjacent brownfield sites. On marshy industrial land by the Thames, Paramount wants to build a £2bn attraction, bigger than the Olympic Park, which will create 27,000 local jobs. To the west is Bluewater shopping centre. Its malls can be linked up by a “Fastrack” bus system already partly in place. Osborne has promised £200m to help and, more significantly, an urban development corporation to speed up planning consent and cooperation between the two borough councils – Labour-controlled Gravesham and Conservative Dartford. Crucially, both councils also support the garden city.
In the cavernous Eastern Quarry, the first residents will move into their homes this month. Ebbsfleet may not currently look particularly scenic but it doesn’t take much imagination to see that this quarry community could be rather lovely. The developer, Land Securities, has spent more than £100m buying and landscaping the site, creating a south-facing slope down to natural lakes. Wooded quarry walls hide the A2 and most of the old industry. Land Securities has already adopted garden city-style principles: 6,000 homes will be arranged in three “villages” with central squares featuring local shops and schools. There will be safe footpaths for children and a green boulevard along which buses will whisk residents to the station, Bluewater or the Paramount development.
Jeremy Kite, leader of Dartford borough council, is confident that Ebbsfleet won’t become another commuter dormitory. “There’s nothing better than a village, whether it’s an urban village or something in the Cotswolds,” he says. “We’ve got local shops – they happen to be Bluewater – we’ve got a local railway station that happens to be 17 minutes from central London and we’ve got a playground which we happen to call Paramount theme park. If we get this right, it should be a really good model community. The notion that a resident would say, ‘My dream is to commute back and forth to Canary Wharf’ is nonsense. It shouldn’t be a dorm, it should be an importer rather than an exporter of people during the day.”
There is one problem with Ebbsfleet garden city: there is already a town here. It is called Swanscombe. The 14,000 residents of Swanscombe and Greenhithe are not the usual Nimbys – I cannot find anyone who is opposed to the new garden city – but many feel like they are being erased from the map.
“The development is not the problem – the problem is everyone is telling us what we need instead of asking us what we want,” says Bryan Read, leader of Swanscombe and Greenhithe town council. “Swanscombe has a lot of history,” he explains as he takes me on a grand tour of the immaculate town hall, community centre and national nature reserve. This became the first geological reserve in the country after a south-London dentist called Alvin Marston found a skull here in 1935. “Swanscombe Man” (now thought to be a woman) was 400,000 years old and lived alongside tigers, cave lions and elephants. Now, her descendants are furious about their disappearing heritage.

“The people of Swanscombe are up in arms about the name ‘Ebbsfleet’, which is a name made up by Eurostar,” says Jeff Harvey, another town councillor. “They are not opposed to the development but to the erasing of our identity. Swanscombe is so steeped in history I don’t know why they want to disregard us. Over the years, people have suffered from the ‘regeneration’ building work and they haven’t had anything back. We’re just not even thought about.”
Developers are alert to community feeling – concerns over the Ebbsfleet name are “a proxy for wider concerns about being left behind”, acknowledges a spokesperson for Land Securities – but it is no wonder local residents feel excluded: the map of the proposed area covered by Ebbsfleet’s urban development corporation includes land all around Swanscombe but misses out the entire existing community. Locals fear the garden city will flourish, leaving Swanscombe its impoverished middle. “It looks like there’ll be a fence around us, or probably a wall,” laughs Harvey, half-joking. “It’s a nice estate, the quarry, but it’s going to spruce up the area and leave Swanscombe looking like a ghetto – it’s a them-and-us type situation.”
Read is desperate to see the necessary road, rail and bus improvements to link old and new communities and stop garden city gridlock. And it is on these infrastructural questions (rather than aesthetics – there is no reason why a garden city can’t be built on brownfield land) that Ebbsfleet falls short of the garden city ideal. It may receive some government subsidies but Ebbsfleet is being built in a largely standard way – with developers compelled to fund modest infrastructural improvements. Rudlin’s prize-winning vision of a new generation of garden cities is much more radical, and based on reviving the garden-city economic model last used for postwar new towns in Britain.
Is Ebbsfleet a garden city? “I wouldn’t say so,” says Rudlin. “It’s a housing estate styled as a garden city. I’m not saying it’s a bad thing, but the aspirations of a garden city can be higher than that.”
At the core of the housing crisis, says Rudlin, are crazy prices – of homes and land. The big winners are landowners. The value of land can rise 200-fold once it has planning permission; this bonanza means that landowners pay huge fees to planning professionals to get planning permission; together, they pocket the huge uplift in the value of the land. Developers are forced to pay so much for land that they can only afford to build cheap standardised homes. “This awful suburbia around our cities is the result of this dysfunctionality of our planning system,” thinks Rudlin.
His big idea is to revive the legislation that created new towns, with a revived “garden cities act” enabling the government to buy land at its “real” pre-planning permission price, as occurs in Germany and the Netherlands. When this land is sold for construction, the money made is used by each new “garden city foundation” to fund proper infrastructure. This more centrally planned model enables plots with infrastructure to be offered to people to build their own homes (or commission a local builder to do so). The popularity of Grand Designs suggests we would love this. And “the number of self-builds in Italy, Austria and France is huge”, says Rudlin. A “plot passport” would prevent the construction of ugly monstrosities, and self-builders, alongside the familiar high-volume house-builders would help hit the annual 200,000 new homes target.
Unfortunately, the politicians who have been quick to apparently embrace garden cities don’t seem to be seriously considering reviving their economic and legislative underpinning. Is there a danger Osborne and Clegg’s adoption of garden cities is just a way to rebadge the same old bog-standard suburban house-building? “Of course there is,” admits Rudlin. “That’s what happened with the original garden cities. Many of them are a pale shadow of what Ebenezer Howard suggested they would be. That’s the downside of an idea that gets traction – people will always take it and water it down and use it as branding rather than content.”

For critics of garden cities, however, they are not the solution but part of the problem. Lord Rogers and the Campaign to Protect of Rural Englandhave both argued we must build on brownfield land before biting into the green belt as Rudlin suggests. Rogers says at least 1.3m fairly low-density dwellings could be built on suitable brownfield land; there are also 400,000 homes with planning permission not yet built. The influential architect fears Rudlin’s garden cities would become car-dependent suburbs that risk emptying existing cities. In response, Rudlin argues that brownfield is not always available where houses are needed. “You can’t just build a load of houses in a northern mill town,” says Rudlin. “If you’re going to accept you don’t grow Oxford – where there are few brownfields and huge pressure for growth – but you do grow Burnley then you’ve got to have a national policy [to tackle geographical economic imbalances].” From an ecological perspective, brownfield is sometimes far more precious than arable green belt, as demonstrated by the controversy over 5,000 homes planned for an old Ministry of Defence site at Lodge Hill, not far from Ebbsfleet. This overgrown barracks is now the best site in the country for endangered nightingales.
Other planning experts fear that garden cities will only worsen the housing crisis. Each morning, Adrian Jones, a town planner and author of Towns in Britain, watches trains from Welwyn Garden City, packed with commuters, pass his London home. “Garden cities were to be self-sufficient communities, not dormitory suburbs,” he says. “There’s a huge nexus of planning and transport issues around the concentration of jobs, power and investment in London. A few more garden cities doesn’t solve the problem, it exacerbates it.” According to Jones, the housing crisis was caused by selling off public housing; it can be solved by building it again. Far better to rent from a public agency than a private one, argues Jones, not least because the public body can borrow money more cheaply than a private landlord.
Given the drastic forecast that we need 6m new homes over the next three decades, is a more radical rethink required? Frances Holliss, anarchitect and academic at London Metropolitan University, identifies garden cities as part of the source of the housing crisis. Victorian social reformers were horrified by urban slums where home-workers were appallingly exploited. Alongside the provision of new social housing, Howard’s garden cities helped establish a principle still embedded in planning regulations today: the separation of work and home. Many social housing tenancy agreements, for example, still prohibit running a business from home. This has created what Holliss sees as “an enormous amount of wastage in our building stock”: homes are empty in the day; huge offices are desolate at night (to say nothing of the money and energy wasted on commuting between them). If more people were allowed to work from home, and offices and industrial spaces were not prohibited as places to live, argues Holliss, we wouldn’t need to construct so many new buildings on green or brown fields. “We need to be more flexible about how we inhabit buildings. Home-based work has a role in terms of making building stock more efficient. We have the potential to inhabit a very wide range of buildings as combined dwellings and workplaces if we can only loosen up the rules. I really don’t believe we need to build more; we need to inhabit what we’ve got in a far more imaginative way.”

Jaime Lerner on Making Curitiba’s First Pedestrian Street

by Elizabeth Press on July 7, 2009

"This is the third installment of videos from Brazil. Demonstrating again how Curitiba Brazil was 35+ years in front of our NYC livable streets curve, this video is about a street transformation.

Former Mayor and founder of Bus Rapid Transit, Jaime Lerner sat down with me during my visit to discuss how and why he made the first pedestrian street in the middle of downtown Curitiba.

Rua XV de Novembro (15th of November Street) is a vital artery through downtown Curitiba. In 1972 under the direction of then Mayor Jaime Lerner, it became the first major pedestrian street in Brazil. The first phase of closing the street to automobiles and opening it to people took place in only 72 hours. The pedestrian plaza spans 15 blocks, and although it was initially unpopular, it is now a central meeting spot and the epicenter of local businesses in the center of Curitiba."

The Politics of Happiness, por Susan Ives

Enrique Penalosa, mayor of
Bogota, Colombia, 1995-1998.
Photo by Susan Ives

"The name Bogota conjures images of kidnapping, murder, and drug wars. But today's Bogota is safer than Washington, D.C., or Baltimore. A visionary mayor discovered the secret to making his city safe. Enrique Penalosa tells Susan Ives the story.

We really have to admit that over the past 100 years we have been building cities much more for mobility than for people's well-being. Every year thousands of children are killed by cars. Isn't it time we build cities that are more child-friendly? Over the last 30 years, we've been able to magnify environmental consciousness all over the world. As a result, we know a lot about the ideal environment for a happy whale or a happy mountain gorilla. We're far less clear about what constitutes an ideal environment for a happy human being. One common measure of how clean a mountain stream is is to look for trout. If you find the trout, the habitat is healthy. It's the same way with children in a city. Children are a kind of indicator species. If we can build a successful city for children, we will have a successful city for all people.
When I was elected mayor of Bogotá and got to city hall, I was handed a transportation study that said the most important thing the city could do was to build an elevated highway at a cost of $600 million. Instead, we installed a bus system that carries 700,000 people a day at a cost of $300 million. We created hundreds of pedestrian-only streets, parks, plazas, and bike paths, planted trees, and got rid of cluttering commercial signs. We constructed the longest pedestrian-only street in the world. It may seem crazy, because this street goes through some of the poorest neighborhoods in Bogotá, and many of the surrounding streets aren't even paved. But we chose not to improve the streets for the sake of cars, but instead to have wonderful spaces for pedestrians. All this pedestrian infrastructure shows respect for human dignity. We're telling people, “You are important—not because you're rich or because you have a Ph.D., but because you are human.” If people are treated as special, as sacred even, they behave that way. This creates a different kind of society.
We began to experiment by instituting a car-free day on a weekday. In a city of about 7 million people, just about everybody managed to get to work by walking, bicycling, bus, even on horseback—and everybody was better off. There was less air pollution, less time sitting in traffic, more time for people to be productive and enjoy themselves. Every Sunday we close 120 kilometers of roads to motor vehicles for seven hours. A million and a half people of all ages and incomes come out to ride bicycles, jog, and simply gather with others in community.
We took a vote, and 83 percent of the public told us they wanted to have car-free days more often. Getting people out of their cars is a means of social integration. You have the upper-income person sitting next to the cleaning lady on the bus.

Parks for urban peace
Parks have a very powerful role to play as equalizers of society. We almost always meet under conditions of social hierarchy. At work, some people are bosses and others are employees; at restaurants, some people are serving and others are being served. Parks are the gathering place for community. They create a sense of belonging. Everybody is welcome regardless of age, background, income, or disabilities. This creates a different type of society.
Today we see images of the beautiful Earth taken from a spaceship, and we think of it as our planet. But in fact, there are very few places on the planet to which the public has access. Most of the land is privatized, and public spaces are very, very scarce. The fact is, upper-income people have always had access to nature and recreation. They go to country houses, golf clubs, restaurants, hunting preserves. What do the poor, especially in the Third World, have as an alternative to television? All poor people have are public spaces, so this is not a luxury. They are the minimum a democratic society can provide to begin to compensate for the inequalities that exist in society.
Since we took these steps, we've seen a reduction in crime and a change in attitude toward the city. In the worst recession we've ever had, people were asked to pay a 10 percent voluntary tax to support various city services, including parks. More than 40,000 people did so, which I think speaks to the greater sense of community people feel.
If we in the Third World measure our success or failure as a society in terms of income, we would have to classify ourselves as losers until the end of time. Given our limited resources, we have to invent other ways to measure success, and that could be in terms of happiness. It may be in how much time children spend with their grandparents, or the ways in which we are able to enjoy our friendships, or how many times people smile during the week. A city is successful not when it's rich but when its people are happy. Public space is one way to lead us to a society that is not only more equal but also much happier.
Perhaps the biggest challenge to world security is environmental and social sustainability in the world's fastest-growing cities. The population of cities in the Third World is growing by more than 80 million inhabitants per year, which means there will be some 2 billion people living in these cities within the next 25 to 30 years. In dense cities such as Bogotá, São Paolo, Jakarta, and Mexico City, there have been practically no places where people can come into contact with nature, safely play outside, or meet others in society as equals. And we have seen firsthand how living in poor conditions can lead to social problems, including extremism and even terrorism. We need food and housing for survival, but there are even higher types of needs—needs related to happiness. If you look at it that way, parks become as necessary to a city's health—physical and spiritual—as the water supply.

For the Danes, city planning is all about the bike, por Gary Mason


Cyclists in central Copenhagen, Denmark.
"From his second-floor office overlooking a Baltic-fed canal, Andreas Rohl ponders a daily question: How can he make life hell for the car drivers of this Scandinavian capital? Mr. Rohl, you see, is the bicycle program manager for the city government of Copenhagen. And it's his job to get more of the almost two million Danes living in Greater Copenhagen out of their cars and onto bikes. And to do that he must find ways of making a daily commute on two wheels more attractive than one on four. “This is what we work on a lot,” said Mr. Rohl, an every-day cyclist who does not own a car. “It's all about normalization: making the experience of getting in and around the city on a bicycle as normal and hassle-free as possible.
“We have reached the point where riding a bike is a far better mode of transportation than a car. You can get almost anywhere faster on a bike than in a car. We focus a lot on increasing bike speeds from point A to point B, and one way you can do that is slowing car speed over that same distance.”
When you think of rush hours in major world centres, you imagine cars inching along, going nowhere fast. But the morning and afternoon commute in Copenhagen is something else entirely. It is a spectacle involving tens of thousands of cyclists roaring down dedicated lanes in tight packs, past cars moving at half the speed, if at all.
Copenhagen is the cycling capital of Europe, and likely the most bike-friendly city in the world. An amazing 37 per cent of those living in Greater Copenhagen use a bicycle to get to work or school every day. That number jumps to 55 per cent if you look only at people living inside the city limits.
Bikes are everywhere: in vast lots outside train stations, leaning against buildings, locked to racks that are as ubiquitous as Carlsberg signs. The people riding them are dressed for all occasions. You see men in pin-striped suits and women in skirts and high heels. Few ride anything but old, traditional one-speeds.
As many cities around the world take the first tentative steps toward building bike cultures of their own, Mr. Rohl has become in demand as a speaker. People want to know how Copenhagen did it. Mr. Rohl tells them it took time and uncommon political courage.
Today, cyclists rule the roads in Copenhagen. There are far more bikes than cars. Where cities in North America focus on easing car congestion, in Copenhagen it's bike jams people like Mr. Rohl are trying to solve. In some cases, that has meant taking space away from cars and handing it to cyclists. It's meant building bridges for bikes and pedestrians over busy thoroughfares.
“Part of finding ways to get even more people biking is to make the experience for cyclists as pleasant as possible,” said Mr. Rohl. “So if you can create peaceful routes for cyclists and give them pleasant views, it makes the trip more enjoyable and they'll be more apt to continue doing it.”
Imagine this: Traffic lights that were once co-ordinated for car speeds were adjusted to cater to the pace of the average cyclist, allowing them to travel long distances without ever getting a red light. To increase safety, stop lines for cars are five metres behind those for bikes. Cyclists get a green light up to 12 seconds ahead of cars to help increase their visibility.
In the winter months, bike ridership drops off 20 per cent. Still, an armada of plows is ready to clear bike lanes when snow flies. They get priority over routes for cars.
You would think that with so many cyclists on the road, the number of accidents and deaths would be enormous. In fact, each year sees an average of two or three deaths, although there were five in 2008. There have been about 120 serious accidents annually in the past few years, a figure that has declined as the number of cyclists on the roads has increased.
Surprisingly, few cyclists in Copenhagen wear a helmet, a matter that local politicians often debate. But there has been a general reluctance to make them mandatory because it might discourage people from riding. The benefits of cycling, both environmentally and healthwise, outweigh the risks of riding without a helmet, Mr. Rohl said.
It's not all perfect, of course. Cyclists want more parking, and the holes and bumps along certain routes repaired. They want dedicated lanes widened to accommodate their growing numbers. But overall, people are happy with the job Mr. Rohl and others have been doing on their behalf.
By the way, if you think the Danes are doing this to save the planet, you're wrong. Only 1 per cent of those recently surveyed by the city said they were riding a bike to help the environment.
The rest said it was just easier to get around that way."

Urban planning needs green rethink, por Martha Schwartz

"When it comes to environmental concerns, there has been altogether too much fragmented talk of buildings.
We have consistently failed to recognise that buildings are situated in wider landscapes that desperately need greater attention.
As I go about my work as a landscape architect, I regularly deal with our profession's role within the green agenda.
Unfortunately, I have found that we lag behind architects when it comes to participating in the conversation around sustainability; in fact, we are often relegated to presiding over green roof technology.
This is most ironic, because landscape architecture is, in fact, the profession that deals with the "green" part of the agenda.
The reason for the focus on buildings, as opposed to that of the surrounding landscape, is down to the fact that the uses of resources and energy can be addressed with a degree of simplicity and directness.
Meanwhile, landscape architects are left outside looking in on the discussion because our professional remit rests outside these technologically oriented and building-focused discussions.
This is problematic because the nature of our profession is to focus on pressing environmental issues in a holistic fashion, in what I call the Softer Side of Sustainability.
This approach involves creating a sense of place, identity and belonging, in order to develop sustainable communities and - I hope - improve the environment.

Living landscape
We seem to have forgotten that sustainability itself is a cultural notion, and that a building or a place must have value to people if it is to be used sustainably.


It is therefore vital that landscape architects assert this both in our advocacy and in our actual work; for so long as we trail behind the architects by topping their buildings with green roofs, we are simply fiddling while Rome burns.
The landscape is the canvas upon which we live our lives, join together as communities and build our cities.
Embedded and integral to the landscape are the ecological systems that must be understood and respected, as well as the infrastructural systems connecting us all together.
I am not simply referring to gardens and majestic wildernesses; in fact, the most sustainable form of human habitation is the city.
This is where we collectively need focus our activities, and this is also where landscape architects can be of real use.
Encouraging people to live side by side more closely will help the local ecology to flourish, because the community can utilise superior water stations and sewage treatment plants, as well as improving electricity consumption patterns.
Cities also inspire a collectivisation of wealth, allowing local governments to better build and equip schools, libraries, and performing arts buildings.
So the reward of collectivisation can be true sustainability. City inhabitants, from a variety of backgrounds, can be quickly made aware of environmentally friendly ways to live.

This, in turn, can result in people influencing one another as they incorporate progressive lifestyle changes into the fabric of their diverse daily lives.
Landscape architects ought to help to make cities better places for all who live within them through the establishment of good connectivity and open spaces, the promotion of public transportation and, very importantly, ensuring water is used responsibly, with run-off being managed and put back into the ground.
In addition, landscape architects ought to ensure developers plant as much as possible so that we have an abundance of trees and permeable surfaces.
Careful and inspired design can make all the difference between a place that is viewed as no real significance to anyone, and a place that attracts people, creates vitality, and is cherished by its inhabitants.
The design of Exchange Square in Manchester, UK, is a good example of how careful attention to a community's history and a site's geology can foster the sort of intellectual and emotional investment in a place that leads to real sustainability.
Exchange Square is a wonderful outdoor living room created from a space that was formerly an ignored and ugly traffic intersection, bombed by the IRA in 1996.
The revamped square is now hugely successful; a vibrant and well-used space for everything from watching soap operas during the lunch hour to greeting the Queen.

10-minute rule
Currently, some urban authorities, such as New York, fall short of implementing the issues around the Softer Side of Sustainability, but they are heading in the right direction.

For example, PLAN NYC, the sustainability agenda for the eastern US concrete jungle, includes a proposal to ensure that all New Yorkers live within a 10-minute walk of a park.

But this reference to parks is the only mention of the landscape in the NYC sustainability agenda.
PLAN NYC is certainly a marvellous commitment to improving the lives of citizens by giving them access to fresh, green, open spaces. But it does not push the envelope quite far enough.
It does not advocate the vital commitment to landscapes that reflects the most forward visual thinking, through dynamic, inspirational design, and structured attentiveness to community histories.
The role of landscape architecture is once again one of green embellishment, adding parks here and there, rather than sustainability agenda-setting through thought-provoking design.
Although NYC embraces its image as the centre of the global contemporary art scene, it has supported neither adventurous architecture nor landscape architecture.
For the best examples of this, we have to look to areas like Germany's Duisberg Nord Parc in the Ruhr Valley, or the beautiful green spaces of the Park Andre Citroen in Paris.
So how are we to implement The Softer Side of Sustainability?
First, we should incorporate the expertise of landscape architects into the planning process leading up to the establishment of sustainability agendas such as PLAN NYC.
This planning process should include measures to encourage compaction of the urban landscape, along with more efficient public transportation.
Secondly, we should increase sustainability education for students of landscape architecture, architecture, and urban development.
Finally, American builders should learn from the design overviews used in much European urban planning, but extend their minds to reflect the sophistication of landscape thinking.
Three straightforward steps, but they are key to deciding whether cities can develop effectively for the 21st Century, or remain mired in yesterday's thinking."
Martha Schwartz is a US-based landscape architect specialising in master plans, art commissions, urban renewal, reclamation and redevelopmen.

Jaime Lerner, Palestra para TED


About this talk
Jaime Lerner reinvented urban space in his native Curitiba, Brazil. Along the way, he changed the way city planners worldwide see what’s possible in the metropolitan landscape.


About Jaime Lerner
From building opera houses with wire to mapping the connection between the automobile and your mother-in-law, Jaime Lerner delights in discovering eccentric solutions to vexing urban problems.…


Why you should listen to him:
For many city governments seeking visible improvements in their congested streets, the pace of change is measured in months and years. For Jaime Lerner, it's measured in hours. As mayor of Curitiba, he transformed a gridlocked commercial artery into a spacious pedestrian mall over a long weekend, before skeptical merchants had time to finish reading their Monday papers.

Since then he's become a hero not only to his fellow Brazilians, but also to the growing ranks of municipal planners seeking greener, more sustainable cities. His dictum that "creativity starts when you cut a zero from your budget" has inspired a number of his unique solutions to urban problems, including sheltered boarding tubes to improve speed of bus transit; a garbage-for-food program allowing Curitibans to exchange bags of trash for bags of groceries; and trimming parkland grasses with herds of sheep.

In addition to serving three terms as mayor of Curitiba, Lerner has twice been elected governor of Parana State in Brazil. His revolutionary career in urban planning and architecture has not only improved cities worldwide, but has also brought him international renown. Among his many awards are the United Nations Environmental Award (1990), the Child and Peace Award from UNICEF (1996), and the 2001 World Technology Award for Transportation.

"Lerner is a longtime proponent of what might be called "blitz urbanism": the rapid, workable improvement that does an end run on bureaucrats and doubters"
Justin Davidson, Newsday
