Urbanisation is not natural or inevitable. It's being inflicted upon us by the forces of capitalism

This is the first in a series of columns entitled “Critical Cities”, which will explore the rise of the “Urban Industry” – and question whether urbanisation is a good thing for the species or the planet.

The much-publicized Urban Age is, ostensibly, upon us. The inaugural and immoderate celebrations for this new phase in human evolution arrived in late 2006, with LSE professor Ricky Burdett’s Venice Biennale exhibition. Celebrations for the world’s urbanisation continue unabashed to this day – even though they have been ever so slightly tempered by capitalism’s latest crisis.

The handsomely sponsored celebrations that ushered in the Urban Age have more recently leapfrogged out from the businesses of architecture, academia and contemporary art. Today the revelries take place in just about every institution and company, everywhere.  Despite the corporate hospitality, popular effervescence and gaiety for all things urban, this might just end up being “the best worst party” – ever. It might just end up being the sort of party you wished you’d skipped, rather than one you helped organise.

In fact, for reasons we will reveal in this column, the land clearances of the world’s population and our centralisation into cities has been systematically championed and actively advocated for. The result of the campaigns means the majority of the world’s population now lives on just 3-4 per cent of Earth’s land surface. We will chart the currently opaque historic and contemporary relationships between NGOs, academia, business, high culture and governments, that make this unprecedented and humanity-changing enterprise possible. These interlinked and interdependent relationships we call “The Urban Industry”.

Those working in The Urban Industry are, knowingly or unknowingly,  marshaling the world off open, verdant and resource rich lands and in to barren, highly controlled, unequal and densely populated urban areas. It is important to be clear the herding and centralisation of the world’s population in to urban areas is by no means natural or inevitable, and it most certainly isn’t an “evolutionary step”. Are those in the Urban Industry on the wrong side of history?

Throughout these articles, we will present evidence that shows that contemporary cities are in fact creators, incubators and perpetuators of poverty and inequality. The urbanisation of the world should not be celebrated.

These facts are in direct contrast to and conflict with the lavishly sponsored meta-narrative of The Urban Industry that repeats over and over that cities are centers of innovation, creativity, happiness, good health and, even astonishingly the cause and the solution for global warming.

Each of the columns will focus on a different aspect or player in The Urban Industry. Academia for example, we reveal, had every opportunity to be the site to challenge the unjust processes causing forced urbanisation. Unfortunately, due to extreme class privilege and institutional racism – particularly prevalent in architecture, urban studies, planning and development studies universities – these academics are instead some of the most easily star struck, post-critical and inadequate people to examine the real causes and effects of the centralisation of the world’s population.

NGOs – like apparent social-minded academics such as Richard Sennett – spend the vast majority of their time ruminating on the challenges of the management, “strong” leadership and protocol needed for big cities to function. Moreover, we will highlight how NGOs such as UN Habitat are sponsored by some of the most dubious and corrupt corporations that favour commercial profits over human rights.

Capitalism’s interest in centralising the world’s population is threefold. Firstly, land clearances transplant the populations in to cities providing unhindered access to mineral resources and the opportunity for large-scale corporate farming. This type of urbanisation also creates a highly vulnerable and mobile workforce, that can easily be exploited on the industrial farms or once in the city they end up in.

Secondly, land clearances and the urbanisation of “traditional cultures” rapidly speeds up the homogenisation, mainstreaming and assimilation of many millions of people into the dominant westernised metropolitan culture – which often then leads to ‘the village’ being seen as backwards, redundant. The fracturing and alienation also significantly reduces the chances of any resistance to the corporate land grabs.

Thirdly, the creation and management of high population, high density, and compact cities is the ideal business environment. “Citizens” are both captured and highly dependent on goods and services and the scale of the market, and the limited geography make cities the ideal business context.

We will also highlight the role of culture being enacted through events like the London Festival of Architecture to advocate for urbanisation and support the false promises underpinning this so called “Urban Age”. Critical Cities is a column that seeks to place the processes that cause urbanisation at the forefront of discussions about cities. The column aims to undress and expose the great myths that lead some of the brightest to be entirely wrong when they suggest “cities are good for us” – and reveal who really wins and loses from the Urban Age.

Green roofs improve cities – so why don’t all buildings have them?

Rooftops covered with grass, vegetable gardens and lush foliage are now a common sight in many cities around the world. More and more private companies and city authorities are investing in green roofs, drawn to their wide-ranging benefits which include savings on energy costs, mitigating the risk from floods, creating habitats for urban wildlife, tackling air pollution and urban heat and even producing food.

A recent report in the UK suggested that the green roof market there is expanding at a rate of 17 per cent each year. The world’s largest rooftop farm will open in Paris in 2020, superseding similar schemes in New York City and Chicago. Stuttgart, in Germany, is thought of as “the green roof capital of Europe”, while Singapore is even installing green roofs on buses.

These increasingly radical urban designs can help cities adapt to the monumental challenges they face, such as access to resources and a lack of green space due to development. But buy-in from city authorities, businesses and other institutions is crucial to ensuring their success – as is research investigating different options to suit the variety of rooftop spaces found in cities.

A growing trend

The UK is relatively new to developing green roofs, and governments and institutions are playing a major role in spreading the practice. London is home to much of the UK’s green roof market, mainly due to forward-thinking policies such as the 2008 London Plan, which paved the way to more than double the area of green roofs in the capital.

Although London has led the way, there are now “living labs” at the Universities of Sheffield and Salford which are helping to establish the precedent elsewhere. The IGNITION project – led by the Greater Manchester Combined Authority – involves the development of a living lab at the University of Salford, with the aim of uncovering ways to convince developers and investors to adopt green roofs.

Ongoing research is showcasing how green roofs can integrate with living walls and sustainable drainage systems on the ground, such as street trees, to better manage water and make the built environment more sustainable.

Research is also demonstrating the social value of green roofs. Doctors are increasingly prescribing time spent gardening outdoors for patients dealiong with anxiety and depression. And research has found that access to even the most basic green spaces can provide a better quality of life for dementia sufferers and help prevent obesity.

In North America, green roofs have become mainstream, with a wide array of expansive, accessible and food-producing roofs installed in buildings. Again, city leaders and authorities have helped push the movement forward – only recently, San Francisco created a policy requiring new buildings to have green roofs. Toronto has policies dating from the 1990s, encouraging the development of urban farms on rooftops.

These countries also benefit from having newer buildings, which make it easier to install green roofs. Being able to store and distribute water right across the rooftop is crucial to maintaining the plants on any green roof – especially on “edible roofs” which farm fruit and vegetables. And it’s much easier to create this capacity in newer buildings, which can typically hold greater weight, than retro-fit old ones. Having a stronger roof also makes it easier to grow a greater variety of plants, since the soil can be deeper.


The new normal?

For green roofs to become the norm for new developments, there needs to be buy-in from public authorities and private actors. Those responsible for maintaining buildings may have to acquire new skills, such as landscaping, and in some cases volunteers may be needed to help out. Other considerations include installing drainage paths, meeting health and safety requirements and perhaps allowing access for the public, as well as planning restrictions and disruption from regular ativities in and around the buildings during installation.

To convince investors and developers that installing green roofs is worthwhile, economic arguments are still the most important. The term “natural capital” has been developed to explain the economic value of nature; for example, measuring the money saved by installing natural solutions to protect against flood damage, adapt to climate change or help people lead healthier and happier lives.

As the expertise about green roofs grows, official standards have been developed to ensure that they are designed, built and maintained properly, and function well. Improvements in the science and technology underpinning green roof development have also led to new variations on the concept.

For example, “blue roofs” increase the capacity of buildings to hold water over longer periods of time, rather than drain away quickly – crucial in times of heavier rainfall. There are also combinations of green roofs with solar panels, and “brown roofs” which are wilder in nature and maximise biodiversity.

If the trend continues, it could create new jobs and a more vibrant and sustainable local food economy – alongside many other benefits. There are still barriers to overcome, but the evidence so far indicates that green roofs have the potential to transform cities and help them function sustainably long into the future. The success stories need to be studied and replicated elsewhere, to make green, blue, brown and food-producing roofs the norm in cities around the world.
