United Nations Habitat estimates that roughly 1 billion people -- or 33 percent of the world's urban population lives in slums. By 2030, according to the UN's human settlement program, that number is likely to double.
The slum dwellers struggle to survive with little clean water and sometimes no electricity around metropolises like Rio de Janeiro, Brazil; Mumbai, India; Lima, Peru; and Istanbul, Turkey. Their shantytowns are usually vast in expanse and dense in population. In Kibera, a slum near Nairobi, Kenya, for example, more than a million people live in an area about the size of New York's Central Park.
When visitors see a squatter city in India or Pakistan or Bangladesh, they observe overwhelming desperation: rickety shelters, little kids working or begging, absence of sanitation, filthy water and air. However, there are many benefits of rural to urban migration for migrants' lives, including reduction in abject poverty, empowerment of women, increased access to healthcare and education and other services. Historically, cities have been driving forces in economic and social development. As centers of industry and commerce, cities have long been centers of wealth and power. They also account for a disproportionate share of national income. The World Bank estimates that in the developing world, as much as 80 percent of future economic growth will occur in towns and cities. Nor are the benefits of urbanization solely economic. Urbanization is associated with higher incomes, improved health, higher literacy, and improved quality of life. Other benefits of urban life are less tangible but no less real: access to information, diversity, creativity, and innovation.
In a recent interview published by Wired Magazine, Stewart Brand, "the pioneering environmentalist, technology thinker", and founder of the Whole Earth Catalog focuses on the positive aspects of urban slums. Brand also makes a counterintuitive case that the booming slums and squatter cities in and around Mumbai, Nairobi, and Rio de Janeiro are net positives for poor people and the environment. Wired asked him to elaborate.
Wired: What makes squatter cities so important?
Stewart Brand: That's where vast numbers of humans—slum dwellers—are doing urban stuff in new and amazing ways. And hell's bells, there are a billion of them! People are trying desperately to get out of poverty, so there's a lot of creativity; they collaborate in ways that we've completely forgotten how to do in regular cities. And there's a transition: People come in from the countryside, enter the rickshaw economy, and work for almost nothing. But after a while, they move uptown, into the formal economy. The United Nations did extensive field research and flipped from seeing squatter cities as the world's great problem to realizing these slums are actually the world's great solution to poverty.
Wired: Why are they good for the environment?
Brand: Cities draw people away from subsistence farming, which is ecologically devastating, and they defuse the population bomb. In the villages, women spend their time doing agricultural stuff, for no pay, or having lots and lots of kids. When women move to town, it's better to have fewer kids, bear down, and get them some education, some economic opportunity. Women become important, powerful creatures in the slums. They're often the ones running the community-based organizations, and they're considered the most reliable recipients of microfinance loans.
Wired: How can governments help nurture these positives?
Brand: The suffering is great, and crime is rampant. We made the mistake of romanticizing villages, and we don't need to make that mistake again. But the main thing is not to bulldoze the slums. Treat the people as pioneers. Get them some grid electricity, water, sanitation, crime prevention. All that makes a huge difference.
The effect of urbanization in defusing the "population bomb" mentioned by Stewart Brand does make sense in Pakistan's context. With increasing urbanization, Pakistan's population growth rate has declined from 2.17% in 2000 to 1.9% in 2008. Based on PAI Research Commentary by Karen Hardee and Elizabeth Leahy, the total fertility rate (TFR) in Pakistan is still the highest in South Asia at 4.1 children per woman. Women in urban areas have an average of 3.3 children compared to their rural counterparts, who have an average of 4.5 children. The overall fertility rate has been cut in half from about 8 children per woman in 1960s to about less than 4 this decade, according to a study published in 2009.
Dramatic declines in fertility are not necessarily good for society. In a book titled "The Empty Cradle", the author Philip Longman warns that the declining birth rates around the world will cause many social and economic problems. As a consequence of declining fertility, by 2050 the population of Europe will have fallen to what it was in 1950. Mr. Longman says this is happening all around the world: Women are having fewer children. It's happening in Brazil, it's happening in China, India and Japan. It's even happening in the Middle East. Wherever there is rapid urbanization, education for women and visions of urban affluence, birthrates are falling. Having and raising children is seen as an expense and a burden.
"So we have a "free rider" problem. You don't need to have children to provide for your old age -- but the pension systems need them." Says Longman, referring to the coming Social Security crunch as the number of retired people rises faster than the number of workers.
In a recent interview with Wall Street Journal, Pakistan's former finance minister Salman Shah explained that "Pakistan has to be part of globalization or you end up with Talibanization". "Until we put these young people into industrialization and services, and off-farm work, they will drift into this negative extremism; there is nothing worse than not having a job," Shah elaborated. But increasing urbanization in South Asia represents both a challenge and an opportunity for India, Pakistan and Bangladesh. It is a challenge because it imposes a rapidly growing burden on the already overcrowded megacities such as Mumbai, Delhi, Dhaka and Karachi. Such a massive challenge will require a tremendous focus on providing housing, transportation, schooling, healthcare, water, power, sanitation and other services at an accelerated pace. But if this challenge can be successfully met, there will be an opportunity to develop the human potential of the rural poor and employ them more productively in the growing industrial and services sectors in the cities. In the case of Pakistan, if the level of robust economic growth, human development and increased urbanization can be sustained to significantly enlarge the South Asian nation's middle class, then there can be hope for genuine and durable democracy to thrive.
