The Implications of Urbanization on Food Security and Child Mortality of the Urban Poor
›In the chapter, “Urban Agriculture and Climate Change Adaptation: Ensuring Food Security Through Adaptation,” of the edited volume, Resilient Cities: Cities and Adaptation to Climate Change – Proceedings of the Global Forum 2010, authors Marielle Debbeling and Henk de Zeeuw assess the viability of urban and peri-urban agriculture (UPA) as a method of climate change adaptation for the urban poor. Debbeling and de Zeeuw assert that UPA increases the resilience of cities by diversifying both food supply and income streams for the urban poor; decreasing the negative effects of “heat island effect,” air pollution, and urban flooding; conserving water and utilizing organic waste; and reducing energy use and greenhouse gas emissions. Given the scale and impact of modern urbanization, the authors write that “the integration of UPA into urban development and master plans, urban land use and zoning plans, as well as active maintenance of the protected agricultural zones…is crucial.”
In “Urban Area Disadvantage and Under-5 Mortality in Nigeria: The Effect of Rapid Urbanization,” published by Environmental Health Perspectives, authors Diddy Antai and Tahereh Moradi found a significant link between the mortality rate of children under five years of age and a poor and disadvantaged urban environment; such an environment is characterized by poor sanitation, overcrowding, a lack of access to safe water, and high levels of disease-inducing air pollution and hazardous wastes. Although urban living may increase proximity to health care and other social amenities, low- and middle-income countries, such as Nigeria, have overstretched their adaptive capacities and the result is poor health indicators. Antai and Moradi predict that the rapid urbanization of Nigerian cities will bring increased infant mortality, unless individual- and community-based policy interventions are implemented to counter the adverse environmental conditions of deprived areas. -
Shall the Religious Inherit the Earth?

“The world as a whole is getting more religious,” said Professor of Politics at the University of London Eric Kaufmann, speaking at the Wilson Center for the launch of his latest book, Shall the Religious Inherit the Earth? Due to their consistently higher birthrates, religious fundamentalists may reverse the tide of secularism within the next century, he said. [Video Below]

Watch: Catherine Kyobutungi on Monitoring the Health Needs of Urban Slums
›Addressing the maternal health needs of the nearly 60 percent of urban residents who live in slums or slum-like conditions will be a critical step to improving maternal health indicators of a rapidly urbanizing Kenya, said Catherine Kyobutungi, director of health systems and challenges at the African Population Health Research Center in Nairobi.
“In some respects, [the urban poor] are doing better than rural communities, but in other ways they are behind,” said Kyobtungi. But, she said, there are many unique opportunities to improve maternal health in slums: “With these very high densities, you do have advantages; with very small investments, you can reach many more people.”
Output-based voucher schemes – in which women pay a small fee for a voucher that entitles them to free, high-quality antenatal care, delivery services, and family planning – have been implemented to help poor, urban women access otherwise expensive services. But poor attitudes towards health care workers, transportation barriers, and high rates of crime still prevent some women from taking advantage of these vouchers, said Kyobtungi. -
Watch: Younger Generation Will Prioritize Health, Education, Human Rights, Says Frederick Burkle
›June 7, 2011 // By Schuyler Null“Unfortunately, in the last two decades, when globalization became the mantra, it was primarily an economic mantra,” said Frederick Burkle, a senior fellow with the Harvard Humanitarian Initiative, visiting scientist at the Harvard School of Public Health, and senior public policy scholar at the Wilson Center. “The mantra was, ‘if you can improve the economy,” he said, “health, education, everything will follow.’”
“With the financial crisis, that proved not to be true,” Burkle said, and as a result, net expenditures in health and education have declined and the private sector, unfortunately, has not filled the gap.
“We really need to redefine globalization,” Burkle said. “And certainly economics will be there…but health, education, and human rights need to be just as dominant as the economics.”
Burke said he expects a gradual realignment of global priorities to come as younger generations come into decision-making roles. “They don’t have political clout right now,” he said, “but when they do…I think we’re going to see all these aspects that I mentioned – even the humanitarian profession becoming a career – accelerated.” -
Watch: Eric Kaufmann on How Demography Is Enhancing Religious Fundamentalism
›May 24, 2011 // By Schuyler Null“There’s a belief, often amongst political scientists and social scientists, that demography is somehow passive and that it doesn’t really matter,” said Eric Kaufmann, author of Shall the Religious Inherit the Earth: Demography and Politics in the 21st Century and professor at Birkbeck College, University of London in this interview with ECSP. “Part of the message of this book is that demography can lead to social and political change.”
“In this case what I’m looking at is the way that demography can change the religious landscape,” Kaufmann said. “It can actually enhance the power of religion, especially religious fundamentalism in societies throughout the world.”
“Purely secular people, who have no religious affiliation, they are leading the move towards very low levels of fertility, even down to the level of one child per woman,” Kaufmann said. On the other hand, fundamentalists are reacting to this trend and deliberately deciding not to make the demographic transition, he said. “In doing so, the gap between secular and religious widens” and is actually more pronounced in places where the two groups collide.
“You can see this in the Muslim world,” said Kaufmann. “If you look at urban areas such as the Nile Delta and Cairo, in those urban cities, women are who are most in favor of Shariah have twice the family size of women who are most opposed to Shariah, whereas in the Egyptian countryside, the difference is much less because they haven’t been exposed to the same modernizing pressures.”
These dynamics affect the Western world as well, especially when you factor in migration, said Kaufmann: “The fact that almost all the world’s population growth is occurring in the developing world, which is largely religious, means that a lot of people are moving from religious parts of the world to secular parts of the world,” he said. “That effects, for example, countries like the United States or in Western Europe, which are receiving immigrants, and it means in the case of Western Europe – which is a very secular environment – that immigrants bring not only ethnic change but on the back of that, religious change; they make their societies more religious.” -
India’s Quest for a Lower Carbon Footprint
›
Between 1994 and 2007, India reduced its carbon dioxide emissions by 35 percent. As a result, the country’s emissions per capita now register at just over a ton per year – less than China (nearly five tons) and much less than the United States (18 tons). On May 10, Wilson Center Public Policy Scholar Ajay Shankardiscussed how India made these reductions, and what the nation plans to do to bring them down further in the decades ahead.
According to Shankar, several factors account for the 35 percent reductions. One is market-based, with high costs having discouraged heavy carbon-based energy consumption. India levied a “huge de facto” carbon tax on all commercial and industrial uses of electricity, which led to prices as much as 80 percent higher than the cost of supply. Another reason is legislation: New Delhi passed a robust energy conservation law. The private sector was a major contributor to the reductions; Shankar pointed out that India is now the world’s largest hub for small fuel-efficiency vehicles, as embodied by the Tata Motors corporation’s Nano car.
Shankar acknowledged the need for further carbon reductions. As India’s economic growth continues and its citizens become wealthier, carbon emissions will likely increase as more people buy cars and invest in air conditioning. Accordingly, the country has announced its intention, by 2020, to lower emissions by 20 to 25 percent from 2005 levels. He identified two carbon-reducing “opportunities” for India in the coming decades. One is to make irrigation more energy-efficient through the use of solar energy.
Another opportunity lies in India’s cities, where 300 to 400 million people are expected to flock over the next two to three decades. Urbanization presents a considerable carbon challenge, given the proliferation of carbon-emitting vehicles and AC units envisioned by such migration. Shankar spoke of the need for “smart cities” replete with “green buildings,” parks, and electric vehicles. He argued that India has created these types of cities before – including Chandigarh, the capital of Punjab Province, back in the 1950s.
Shankar stated that solar and nuclear energy constitute the “game-changers” for lessening the country’s carbon emissions. New Delhi hopes to generate 20,000 megawatts of solar capacity by 2020, with projections of grid parity by 2017 – meaning that in just several years, solar power could be as cheap to generate as fossil-fuel-driven electricity. He also underscored the priority New Delhi places on nuclear energy, noting that Prime Minister Manmohan Singh was willing to stake his political survival on the passing of a controversial civil nuclear deal with Washington because of nuclear’s environmental benefits. Shankar insisted that the Indian government will not be deterred by Japan’s recent nuclear crisis.
While Shankar described New Delhi’s 20 to 25 percent reductions goal as “ambitious,” he contended that he is more optimistic than he would have been several years ago about India’s prospects for attaining that objective. India, he concluded, must “rule out no option, and pursue every option intelligently.”

Population Growth and Climate Change Threaten Urban Freshwater Provision
›May 6, 2011 // By Emanuel FeldBy 2050, more than one billion urban dwellers could face perennial freshwater shortages if major improvements are not made to water management practices and infrastructure, according to a recent study published in the journal PNAS, “Urban Growth, Climate change, and Freshwater Availability.” These challenges will arise as hydrologic changes due to climate change compound “an unprecedented wave of urban growth,” with nearly three billion additional urban residents forecast by 2050. “It is a solvable problem,” the study argues, “but one that will take money, time, political will, and effective governance.”
Using demographic data from the Earth Institute at Columbia University, as well as a variety of climate and city-level demographic scenarios, the researchers estimate per-capita water availability for cities in the developing world, where urban growth will be most rapid. They advise, however, that their findings should be taken as conservative estimates, since the study assumes cities can use all nearby water and does not account for key challenges relating to water quality and delivery to urban centers.
In 2000, 150 million people in developing countries lived in urban areas that could not support their own water requirements (i.e. less than 100 liters available per person per day). By 2050, according to the study, urban population growth alone could bring this figure to 993 million and more than three billion could face intermittent shortages at least one month out of the year. When the researchers expanded the area on which cities can draw upon to include a 100 km buffer zone, these values drop to 145 million and 1.3 billion, respectively.
However, once climate and land use change are included in the models, the aggregate number of people facing perennial shortages rises a further 100 million, if only water stores within the urban area are considered, or 22 million, for the 100 km buffer zone model.
Remarkably, these aggregate figures differ very little among the various demographic and climate scenarios. The particularities of the challenge do however vary at the regional level. Perennial water shortage will generally be limited to cities in the Middle East and North Africa. Seasonal water shortages, on the other hand, will be geographically widespread, although rapidly urbanizing India and China will be especially hard hit.
The study acknowledges the temptation to view water shortage “as an engineering challenge.” Still, the lead author, Rob McDonald of The Nature Conservancy, cautions against exclusive reliance on grey infrastructure solutions (e.g. canals and dams) in an article for Nature Conservancy, saying:Some new infrastructure will be needed, of course – that’s the classic way cities have solved water shortages. But especially in parts of the world where there’s lots of cities, just going out farther or digging deeper to get water can’t be the only solution.
Instead, McDonald and co-authors Pamela Green, Deborah Balk, Balazs M. Fekete, Carmen Revenga, Megan Todd, and Mark Montgomery, emphasize the need for cities to encourage more efficient water use by their industrial and residential sectors, as well as the potential to engage the water-intensive agriculture sector in surrounding rural areas.
“Bottom line,” McDonald said in an interview with Robert Lalasz of The Nature Conservancy’s Cool Green Science blog, “don’t think of those high numbers as a forecast of doom. They are a call to action.”

Accessing Maternal Health Care Services in Urban Slums: What Do We Know?
›“Addressing the needs of urban areas is critical for achievement of maternal health goals,” said John Townsend, vice president of the Reproductive Health Program at the Population Council. “Just because there is a greater density of health services does not mean that there is greater access.”
Townsend moderated a discussion on the challenges to improving access to quality maternal health care in urban slums as part of the 2011 Maternal Health Dialogue Series with speakers Anthony Kolb, urban health advisor at USAID; Catherine Kyobutungi, director of health systems and challenges at the African Population Health Research Center; and Luc de Bernis, senior advisor on maternal health at the United Nations Population Fund (UNFPA).

Mapping Urban Poverty
“Poverty is becoming more of an urban phenomenon every day,” said Kolb. With over 75 percent of the poor in Central Asia and almost half of the poor in Africa and Asia residing in cities and towns by 2020, “urban populations are very important to improving maternal health,” he added.
Collecting accurate data in informal settings such as slums can be very challenging, and there is often a “systematic undercounting of the urban poor,” said Kolb. Data often fails to capture wealth inequality in urban settings, and there is often a lack of attention to the significant variability of conditions between slums.
Kolb also warned about the risk of generalization: “Slums and poverty are not the same.” In practice, there is not a standardized definition of what constitutes a slum across countries, he said. “It is important to look at different countries and cities individually and understand how inequality is different between them.” Slum mapping can help to scope out challenges, allocate resources appropriately, and identify vulnerability patterns that can inform intervention design and approach, he said.
Maternal Health in Nairobi Slums
Addressing the maternal health needs of the nearly 60 percent of urban residents who live in slums or slum-like conditions will be a critical step to improving maternal health indicators of a rapidly urbanizing Kenya, said Kyobtungi.
Only 7.5 percent of women in Kenyan slums had their first antenatal care visit during their first trimester of pregnancy and only 54 percent had more than three antenatal care visits in all – rates significantly lower than those among urban women in non-slum settings.
“In some respects, [the urban poor] are doing better than rural communities, but in other ways they are behind,” said Kyobtungi. But, she said, there are many unique opportunities to improve maternal health in slums: “With these very high densities, you do have advantages; with very small investments, you can reach many more people”
Output-based voucher schemes – in which women pay a small fee for a voucher that entitles them to free, high-quality antenatal care, delivery services, and family planning – have been implemented to help poor, urban women access otherwise expensive services. But poor attitudes towards health care workers, transportation barriers, and high rates of crime still prevent some women from taking advantage of these vouchers, said Kyobtungi.
The majority of maternal health services in slums are provided by the private facilities, though size and quality vary widely. “There is a very high use of skilled attendants at delivery, but the definition of skilled is questionable,” said Kyobtungi
“Without supporting the private sector,” Kyobutungi said, “we cannot address the maternal health challenges within these informal settlements.” Combined with an improved supervision and regulation system, providing private maternal health facilities with training, equipment, and infrastructure could help to improve the quality of services in urban slums, she concluded.
Reducing Health Inequalities
“While we have evidence that health services, on average, may be better in urban areas than in rural areas, this often masks wide disparity within the population,” said de Bernis. “Reducing health inequities between and within countries is a matter of social justice.”
When it comes to family planning, total fertility rates are lower in cities, but “the unmet need…is still extremely important in urban areas,” explained de Bernis. Many poor women in cities, especially those who live in marginalized slum populations, do not have access to quality reproductive health services – a critical element to reducing maternal morbidity and mortality rates.
Economic growth alone, while important to help improve the health status of the poor in urban settings, will not solve these problems, said de Bernis. To reduce health disparities within countries, de Bernis advocated for “appropriate social policies to ensure reasonable fairness in the way benefits are distributed,” including incorporating health in urban planning and development, strengthening the role of primary health care in cities, and putting health equity higher on the agenda of local and national governments.
