Urban populations across the South are growing fast: by 2030, some 5 billion people around the world will live in cities. This year will be the first year in which urban dwellers (3.3 billion people) will outnumber rural residents for the first time (UNFPA).
Africa now has a larger urban population than North America and 25 of the world’s fastest growing big cities. Asia and Africa’s cities are growing by an incredible 1 million people a week, with 72 per cent of the population in sub-Saharan Africa living in slum conditions.
How well people dwell is integral to their mental and physical health. Most squatters and slum dwellers – a category that includes half the urban population of Africa, a third in Asia and a fourth in Latin America and the Caribbean – live in makeshift homes made from whatever they can get their hands on. These dwellings are usually unsafe and vulnerable to fire, floods, and earthquakes. On top of this, these sprawling slums can be depressingly grim to look at for those living there.
In Brazil’s Sao Paulo neighbourhood of Heliopolis – the largest of the city’s 400 favelas, or shantytowns – the majority of its dwellings are made from cement and brick. It is stigmatised as the ugliest part of the city, yet a unique initiative has transformed perceptions of the area – and brought pride to its residents. The project offers a model for slum areas looking to make the next leap up the ladder of development. Heliopolis first sprang up in the 1970s, wedged between highways and roads. Plagued by crime, there is a wide spread in incomes and urbanisation among the 120,000 residents packed into the one-and-a-half square mile. Older parts have many services, while newer areas lack basics like plumbing and electricity.
Well-known Sao Paulo-based Brazilian architect Ruy Ohtake (http://www.geocities.com/capitolhill/3836/saopaulo.html) mobilised the 6,000 residents to use a fixed palette of six colours – from bright yellow to deep purples – to create a look described as akin to an Italian hill town.
“Ohtake told a newspaper that Heliopolis was the ugliest part of the city, so we went to him and asked him to figure out how to make it beautiful,” Geronino Barbosa, director of the Heliopolis community group UNAS, told the design magazine Dwell.
Ohtake, famous for his hotel designs and renovating former colonial areas, rose to the challenge: “I believe in beauty as a social function, so what better way to exercise that belief,” he said. To avoid the initiative feeling like something being imposed from on high, the plan did not go ahead until the residents were happy. And to make sure they felt they owned the results, they did all the painting themselves. The result is a river of colour running through a landscape of dreary, unfinished brick homes jammed between streets and factories. The Italian hill town-effect leaves pedestrians experiencing a surprise as they turn through the streets, happening upon hidden plazas and little bars.
“Our dream is to expand this project to the entire favela,” said Barbosa. “People love their painted houses. One of our participants told me that her house has been transformed into a sort of Carnival parade.”
“Who doesn’t want to live in a beautiful house?” said UNAS’ head, Joao Miranda, to Dwell. “We want the same things as everyone else.”
Another architect has tackled the problem of how to create inexpensive but durable and beautiful homes for the poor. Iranian-born architect Nader Khalili (http://www.calearth.org/) has created what he calls ‘super adobe’ dwellings inspired by traditional Iranian rural homes. The cone-shaped homes are made from sandbags piled one on top of the other in a circular pattern. A basic home is three rooms of 400 square feet, and can be built by five people (with only one needing skills), within weeks. Being sandbags, the homes can easily be dismantled and moved or adapted to meet new space needs.
Khalili first fell in love with the sand adobe homes of Iran in the 1970s. He had been on a journey to find a home design that was both environmentally harmonious and could be built anywhere in the world quickly and cheaply. But while the original Iranian sand adobe is easily destroyed by earthquakes and bad weather, the ‘super adobes’ are earthquake, hurricane and flood resistant. They are now being built across the Americas , Asia and Africa.
“You can never build one of these that doesn’t look beautiful,” he said. “Just as you have never seen an ugly tree or an ugly flower.”

A clash is occurring across the global South over the future of urban planning and the ever-growing slums of the world’s megacities. This will be a decisive clash of visions: should cities flatten slums and relocate their residents, or work with slum dwellers, acknowledge the role they play in city economies and improve their lives with better dwellings?
As the world turned into a majority urban place in the 2000s, cities grew at a phenomenal rate. The cities of Africa and Asia are growing by a million people a week, according to some estimates. Megacities and sprawling slums will be the hallmarks of this new urban world, it seems. In sub-Saharan Africa, 72 percent of the population already lives in slum conditions.
The danger of building unsafe or makeshift homes can be seen in 2010’s devastating earthquake in Haiti, where many buildings collapsed, killing thousands.
One of the Philippines’ leading architects and urban planners, Felino A. Palafox Jr. of Palafox Associates (www.palafoxassociates.com), is passionate about re-making the slums in his country’s capital, Manila. The city is prone to devastating and sometimes deadly flooding. Palafox believes the vulnerability of slum dwellings and poor urban planning are placing lives at risk.
“We can’t wait for another tragedy,” Palafox told the Philippine Daily Inquirer in 2010. “We have seen how an unprecedented volume of rainfall like what (storm) Ondoy had brought could prove too much for Metro Manila’s river and drainage system. We have also seen what a massive earthquake could do to an unprepared city like Haiti.
“While there is nothing that we could do to control the destructive power of these natural phenomena, there are steps that we could take to limit the amount of damage.”
If the rapid growth in urban populations is to be safe and sustainable, then new dwellings will need to be built that meet high standards of durability.
The UN Challenge of Slums report from 2003 (www.unhabitat.org/pmss/listItemDetails.aspx?publicationID=1156) broke with past orthodoxy that slums must be cleared, arguing that slums should be seen as positive economic forces, incubators for budding entrepreneurs that offer a gateway to better things for new migrants.
Muhammad Khadim of UN-Habitat summed up the new thinking:
“Ten years ago, we used to dream that cities would become slum-free,” he said. But “the approach has changed. People see the positives. The approach now is not to clear them but to improve them gradually (and) regularise land tenure.”
The arguments behind embracing slums come from the economic changes across developing countries since the 1970s. Growing informal economies combined with fewer social provisions and the shift to urban from rural communities have all contributed to the explosion in slums and informal housing.
Manila is a city of stark and startling contrasts: there are glitzy shopping malls and high-rise office buildings, but also large slums and hungry people begging and selling trinkets on the city’s roads.
It’s a place where the slum clearance-vs-renovation debate is hot and current. The Philippines is currently in the midst of a campaign to clear slums in Manila and move people back to the countryside.
“Many of our people are no longer interested in agriculture, so we need to give them incentives to go back,” Cecilia Alba, head of the national Housing and Urban Development Co-ordinating Council, told the New Statesman magazine. “If we had to rehouse the slum-dwellers inside Manila in medium-rise housing, it would cost a third of the national budget.”
Palafox has a different vision – rebuilding a slum community from top to bottom.
An architect, environmental planner, urban planner and development consultant, Palafox runs one of the top architecture firms in the Philippines, employing more than 100 staff and consultants.
Usually occupied with office buildings in the go-go new business centres of the Middle East and Asia, Palafox has turned his attention to Estero de San Miguel, a Manila slum that is home to some 1,200 families, or 6,000 people.
Families are packed into tiny rooms in a labyrinthine slum complex beside a canal. The rooms are made of wood and floored with linoleum and have to be accessed through a narrow tunnel and tight connecting corridors.
Palafox’s plan is to work with the residents and rebuild it in its current location. In place of makeshift shacks will come modular homes, 10 square metres in size with space for shops and bicycle parking.
The design has the homes extend above a walkway, imitating the way the original slum structures were built.
Palafox is applying innovative thinking to the problem: taking his design direction from the dwellings slum residents build: “The slum-dwellers,” he explained to the New Statesman, “are experts at live-work space design. They spontaneously do mixed-use! We just have to learn from them.”
Re-housing the residents on site means they can continue to play their role in the city’s economy, and do not have to make a long commute to jobs and opportunities.
Palafox also rebuts complaints about the cost of his plan, arguing the scale of corruption in the Philippines costs just as much.
“OK, the total cost of rehousing slum-dwellers in situ is 30 per cent of GDP (but) I calculate we lose about 30 per cent of the country’s wealth through corruption. If we didn’t have corruption, we wouldn’t need to tolerate slums.”
“We have to recognize the value of slum-dwellers to the city,” he said. “These are the ones who drive your car, clean your house and run your store. If these people were cleared from the city, the city would die. Slum-dwellers add social, political and economic value to the city.”
Even in its current form, Estero de San Miguel is a vibrant place, with an Internet café and a volunteer police force.
A BBC report found it lively and economically viable because it has educational and communication technologies that improve living conditions. The residents make their living working as cheap labour for the city.
Oliver Baldera, a carpenter, lives with his wife and four children:
“We’ve been here more than 10 years,” he told the New Statesman. “There’s no choice.
“It’s easier to get a job here and I can earn 400 pesos a day. I can send the kids to school and they eat three times a day – but it’s not enough. I need more space.”

Launched in May 2011, the new global magazine Southern Innovator (ISSN 2222-9280) is about the people across the global South shaping our new world, eradicating poverty and working towards the achievement of the Millennium Development Goals (MDGs).
The transition to a green economy has reached a crossroads: while multilateral global initiatives have been long-running and complex, the idea of a green economy still seems fragile and achieving it far from certain. In the face of the ravages of the global economic crisis that has raged since 2007/2008, countries are now trying to roll back their green pledges or slow the pace of transition.
This exposes a dilemma: a perception that a green economy is in conflict with economic growth, prosperity and the advance of human development, particularly in developing countries seeking to make rapid gains in reducing poverty and building a middle class, consumer society.
Three things need to be foremost in the minds of those who care about creating a global green economy in the 21st century: innovation in design, in market prices and in business models. I think these three factors will be the deciding elements in whether green technologies are taken up quickly and used by large numbers of people to improve their lives.
The green option needs to always be the more appealing, cheaper option that also improves living standards. Happily, many people are doing this all around the world – you just may not have heard of them yet (unless you are reading Southern Innovator magazine that is).
As editor of the magazine Southern Innovator since 2011, I have had the privilege to meet, interview and see first-hand green economy innovators across the global South and profile them in the magazine. What has stood out for me is this: the ones who have achieved sustainable success have put a great deal of effort into design – how the technology is made, what it looks like and how it is used, how efficiently it is made and distributed – while also thinking through the business case for their work and how to make it appealing to others.
We have tried to apply this thinking to the magazine as well, by using clear and modern design with bright, eye-pleasing colours, and by choosing to use 100 per cent renewable energy (much of it from geothermal sources) for the magazine’s design and layout and to have it printed on paper from sustainable forest sources.
The fourth issue of Southern Innovator (www.southerninnovator.org), on cities and urbanization, launched in October at the Global South-South Development Expo 2013 in Nairobi, Kenya. It profiles many practical initiatives and innovators that are currently building green homes, communities and even whole cities. The magazine’s fifth issue will focus on the theme of waste and recycling and hopes to be a one-stop source of inspiration to better use the finite resources of planet earth.
The coming wave of technological innovations aimed at global South cities will dominate civic debates whether people wish it to or not. Already, futuristic, 21st-century cities are being built around Asia from scratch. I had the privilege of visiting a couple of them in 2012 while researching the fourth issue of our magazine, Southern Innovator ( h t t p : / / w w w . s c r i b d . c o m / SouthernInnovator). Each city had a different focus for its construction – one was seeking to be an “eco-city” and the other one called itself a “smart city,” focused on becoming a regional business and technology hub. Both aimed to use the latest information technologies to make the way Asian cities operate on a day-to-day basis smarter – and greener.
Large information technology companies – including India’s Infosys (infosys.com) – have their sights set on selling all sorts of technological solutions to common problems of urban living. This aspiring revolution is built on two foundations: One is the Internet of Things – in which everyday objects are connected to the Internet via microchips. The other is Big Data, the vast quantities of data being generated by all the mobile phones and other electronic devices people use these days.
Much of this new technology will be manufactured in Asia, and not just that – it will also be developed and designed in Asia, often to meet the challenges of urban Asia.
By their nature, cities are fluid places. People come and go for work and pleasure, and successful cities are magnets for people of all backgrounds seeking new opportunities. This fluidity puts stress on cities and leads to the constant complaints familiar to any urban dweller – inadequate transport, traffic jams, air pollution, poor housing, and a high cost of living.
If handled well and with imagination, new information technologies can ensure Asian cities do more than pay lip service to aspirations to improve human development. They can make cities resilient places – able to bounce back from disasters, whether man made or natural.
During the late 1990s, I saw first-hand the pressures placed on one Asian city, Mongolia’s capital, Ulaanbaatar. The country endured the worst peacetime economic collapse since World War II while confronting the wrenching social and economic stresses of switching from a command economy during Communism to a free-market democracy. The city’s population grew quickly as rural economies collapsed and poverty shot upwards. I can only imagine now how the response could have been different with the technologies available today.
“A lot of social initiatives based on the right to the city are coming from these ‘new cities of the South,’” Mathivet said. “The book highlights original social initiatives: protests and organizing of the urban poor, such as the pavement dwellers’ movements in Mumbai where people with nothing, living on the pavements of a very big city, organise themselves to struggle for their collective rights, just as the park dwellers did in Osaka.”
Recently, an Indian restaurant uploaded to the Internet a video of what it claimed to be the first drone delivering a pizza in an Indian city. While this may or may not be a practical solution to traffic congestion, the subsequent negative fallout – angry police and public officials – from this use of new technology highlights the promise and perils of innovating in the real world of Asian cities (http:/ /www.bbc.co.uk/news/ b l o g s – n e w s – f r o m – elsewhere-27537120).
Micro electronics are becoming cheaper and more powerful by the month. Small businesses armed with a only laptop computer, access to the Internet and/or mobile phone networks, and cloud computing services, can offer very powerful business and public services solutions. And sharing solutions across the global South via information technologies has never been easier.
The U.S. Pentagon published various reports and studies in the 2000s forecasting a dark future for cities in the global South. As author Mike Davis revealed in his seminal work, Planet of Slums (http://www.amazon.com/exec/obido/ASIN/1844670228/nationbooks08), the Pentagon saw the developing world’s cities as the “battlespace of the twenty-first century.” It imagined sprawling, crime ridden cities full of poverty and slums and needing tiny drones and robots darting back and forth, keeping an eye on everything and suppressing unrest. This threat-based view of future cities is one to be avoided. It is possible, through the right application of quick solutions to the challenges that arise as cities grow, to turn to cooperation across the cities of the global South to avoid this pessimistic fate.
Fast-growing cities and urban areas in the global South can be vulnerable because they lack the web of structures and institutions that enable more long-established cities to mitigate risks and, when a disaster does strike, to bounce back quickly. But thanks to many new technologies, and some smart new thinking, it is possible to bring resilience to even the poorest and most deprived urban communities.
The essence of resilience is to build into plans and daily activities a community’s ability to weather any disaster, small or large. All cities, rich or poor, can experience a disaster of some sort, be it weather, civil unrest, war, earthquakes, shortages, or economic, financial and health crises. New technologies make it possible for all cities, no matter how poor and overcrowded, to build in urban resilience. The ubiquity of mobile phones introduces a powerful city and urban planning tool. Mapping chaotic and unplanned areas is already underway in many cities of the global South (in Brazil and Kenya for example (http://tinyurl.com/qgba8kb).
Impressively, innovators in the South are using affordable microelectronics in the form of mobile phones and laptops to gather data and map it. This computing capability was once the sole domain of big information technology companies such as IBM. Now, a single laptop computer combined with a smartphone equipped with the right software can manage a large urban area, a task that once required rooms full of computers. The data can then be used to manage growth today and re-build after a disaster. Any excuse not to be resilient has been wiped out with this technological leap.
But how to deal with the common reality of feeling overwhelmed by the many obstacles to rational planning and building for urban growth in the South? Innovators have stepped in to take matters into their own hands with simple construction technologies as the solution. One example is the Moladi system of recycled plastic moulds (moladi.net). Anybody can master this simple building technique, as the mortar-filled moulds are designed to fit easily together to construct an earthquake-resistant, beautiful home.
This approach has the advantage of bypassing the failings of authorities to enforce building codes and standards in poor, urban communities, creating safer places to live and preventing the growth of unregulated shanty towns at risk to fire and earthquakes.
Others have found social ways to organize people, even in the most desperate of conditions, providing services and laying down the groundwork for an upgrading of an urban area to improve living conditions and long-term opportunities. The concept of ‘cities for all’ has inspired many to re-energize civic organizations and networking in poor areas to ensure they are not left out of economic growth. In Colombia, a famous example of this is the escalator in the city of Medellin, which connects a hillside slum to the centre of the city, opening up economic opportunities to all (http://tinyurl.com/nm47d3u).
Still more exciting, new technologies are in the works to simplify construction of major infrastructure and new buildings. A future city will be able to gather extensive data on an expanding urban area, make detailed development plans with architects and engineers, and then have robots and 3D fabricating machines quickly lay down infrastructure and erect buildings. Sounds far-fetched? Well, in China one company recently used a 3D machine to make 10 houses in a single day (http://www.yhbm.com/index.aspx).
An infographic from Southern Innovator’s fourth issue (http:// tinyurl.com/m9vfwur) shows 10 ways any urban area – either planned or unplanned – can build in resilience. All are proven approaches from cities in the global South.
Southern Innovator’s upcoming sixth issue will explore the interplay of science, technology and innovation in the global South and how people are making the most of 21st century advances to increase wealth and improve human development. Hopefully, all of this innovation will lead to more resilient cities in the future!
