Richard Black: Future Climate-Migration Interactions Will Stress Cities, “Trap” Vulnerable Populations
›“In a 50-year time span, climate change, in particular, is likely to have a quite a strong impact on the drivers of migration,” said Richard Black, professor of human geography at University of Sussex and lead author of Migration and Global Environmental Change: Future Challenges and Opportunities. “But in a way that is different to what has been understood until now.”

Call for Papers: Reducing Urban Poverty
›The Woodrow Wilson Center’s Comparative Urban Studies Project, USAID, the International Housing Coalition, the World Bank, and Cities Alliance are teaming up a third time to co-sponsor an academic paper competition for graduate- and PhD-level students focused on challenges facing urban centers in the developing world.
The themes of this year’s competition are land markets, global climate change, and youth.
Land Markets: The absence of efficient land and housing markets and lack of secure tenure for both renters and owners are impediments to urban and economic development in developing cities. Papers on this topic should explore strategies and approaches that would enable property markets to function better and would provide increased security of tenure and strengthened property ownership rights.
Global Climate Change: Papers should examine how urban populations, especially the poor, are coping with the impacts of climate change, and provide strategic policy analysis to better understand how cities can become more resilient to climate change impacts.
Youth: Most of the youth of the developing world are now or will soon be living in urban areas. Unfortunately, they are often growing up in the poorest urban areas – informal settlements and slum communities where their opportunities for advancement are limited by a variety of negative factors. Papers focused on youth should explore ways to build capacity so that you can develop knowledge and skills, find gainful employment, and participate more fully in society to advance economic growth and social development.
Winning papers from each category will be published and the authors invited to Washington, D.C. in the fall of 2012 for a policy workshop with subject matter experts. Additionally, one grand prize winner will be asked to present his or her work at the World Urban Forum (WUF). WUF was established by the United Nations to examine rapid urbanization and its impact on communities, cities, economies, climate change, and policies. The sixth WUF will be held from September 1-7, 2012 in Naples, Italy and will be focused on “The Urban Future.” In addition to the Washington conference and publication of his or her paper, the grand-prize winner will be invited to present his or her winning paper on a panel at the World Urban Youth Assembly at WUF on September 1st and 2nd.
The deadline for the submission of abstracts is February 20, 2012.
For detailed competition guidelines and requirements, and further information on the sub-topics, please see the full call for papers.

George Washington University’s PISA Helps Share Rural Vietnamese Climate Adaptation Strategies
›“Climate change is not a topic of debate in Vietnam, it’s a real challenge to future prosperity and security,” says George Washington University’s Partnerships for International Strategies in Asia (PISA) program in this video about their climate adaptation and mitigation work in Nam Dinh province. “[Vietnam’s] population density (265 people/square kilometer), its long coastline (3,444 km), its two major rivers (the Red and Mekong) – all help make it one of the 10 countries considered most vulnerable to climate change,” the narrator says.

Reducing Urban Poverty: A New Generation of Ideas
›Download Reducing Urban Poverty: A New Generation of Ideas from the Wilson Center.
In 2008 the global population reached a remarkable turning point; for the first time in history, more than half of the world’s people were living in cities. Moving forward into the 21st century, the world faces an unprecedented urban expansion with projections for the global urban population to reach nearly five billion by the year 2030. Virtually all of this growth will occur in the developing world where cities gain an average of five million residents every month, overwhelming ecosystems and placing tremendous pressure on the capacity of local governments to provide necessary infrastructure and services. Failure to incorporate urban priorities into the global development agenda carries serious implications for human security, global security, and environmental sustainability.
Recognizing a need to develop and strengthen urban-focused practitioner and policymaking ties with academia, and disseminate evidence-based development programming, the Wilson Center’s Comparative Urban Studies Project, USAID’s Urban Programs Team, the International Housing Coalition, the World Bank, and Cities Alliance teamed up to co-sponsor an academic paper competition for graduate students studying urban issues. The first competition took place in the months leading up to the 5th World Urban Forum, held in Rio de Janeiro in March 2010.
This publication, Reducing Urban Poverty: A New Generation of Ideas, marks the second annual academic paper competition. “Reducing urban poverty” was chosen as the theme with each author focusing on one of three topics: land markets and security of tenure; health; and, livelihoods. A panel of urban experts representing the sponsoring institutions reviewed 70 submitted abstracts, from which 16 were invited to write full length papers. Of these, six were selected for this publication. We congratulate the graduate students who participated in this competition for their contribution to our understanding of the complex relationship between urbanization and poverty.
These papers highlight the new research and innovative thinking of the next generation of urban planners, practitioners, and policymakers. It is our hope that by infusing the dialogue on these issues between the academic and policy worlds with fresh perspectives, we will foster new and innovative strategies to reduce global urban poverty.

Maternal Health in Kenya: New Research Unnecessary, Time to Address Existing Gaps
›The original version of this article, by Emily Puckart, appeared on the Maternal Health Task Force blog.
During the recent Wilson Center/African Population and Health Research Center meeting in Nairobi on improving health systems through a maternal health framework, participants focused on knowledge gaps in the Kenyan health system that can negatively affect maternal healthcare. This focus on gaps sparked discussion around research needed (or not needed) in the maternal health field, supply gaps, and gaps between addressing technical, medical issues of maternal health (like preeclampsia or postpartum hemorrhage), and larger society-wide gaps like gender equity. The gaps highlighted by participants at the Nairobi dialogue included:- Gaps in knowledge: During the dialogue, members of the Kenyan maternal health community discussed the possibility of strengthening community health workers as an information delivery platform. Participants wondered about the possibility of using community health workers to distribute information both downward to the end user (patients), and then again to gather information from end users and distribute it upwards through the system to reflect the opinions of the direct users of the healthcare system.
- Supply gaps: Participants argued that while there is a large body of information in terms of maternal health supplies at the national level in Kenya, there is not as much data on supplies at the actual health facility level, where it is much needed and would be very helpful to successfully treat patients.
- Gaps in healthcare delivery: There is a strong need to address inequality in the distribution of health services as there are unequal services in rural and urban areas. Within those broad areas there may be further inequalities, as even in urban areas, slum areas or neighborhoods on the edges of cities may have less access to quality healthcare than populations that live in wealthier areas of the city or closer to the city center. Further there are broader questions of gender and access to care. Where women are not able to control household finances, they may be unable to access and pay for lifesaving care. Participants framed the question in a rights framework, “Do we value the lives of women less than men?”
- Health workforce gaps: There is a mismatch between the supply of health workers and the absorption of those trained health workers in Kenya. Many of them are not incentivized professionally or financially to stay in the system where they are trained. These health workers may leave for other countries or prefer to stay in urban areas depriving rural areas of a surplus of trained health workers.
- Gaps between words and actions: Several of the small working groups pointed to accountability as a serious issue, as there are gaps between the words of politicians on health issues and actual actions. The gap between the government promised funding for health and the actual lower amount of spending was consistently highlighted during the Nairobi dialogue as a serious gap in holding governments accountable for their promises.
The lively conversation provoked by a broad discussion of gaps in the Kenyan health system provided fertile ground to develop action points on maternal healthcare that participants then presented on the second day of the meeting to several Kenyan members of parliament. Ideally, this will be the first discussion of many as maternal health advocates, field workers, and researchers coalesce around ways to address the gaps in maternal healthcare in Nairobi and elsewhere.

Twin Challenges: Population and Climate Change in 2050
›With global population reaching 7 billion, a lot of attention has been paid to the question of how to sustainably support so many people, much less the 9 billion expected by 2050, or the 10 billion possible by 2100. Add in the environmental variability projected from climate change and the outlook for supporting bigger and bigger populations gets even more problematic. Two new maps – one by the Population Reference Bureau (PRB), the other by McGill University PhD candidate Jason Samson – show how the world might change over the next 40 years in the face of these twin challenges.
Nine Billion in 2050
PRB’s map, built using their DataFinder tool, shows the world in 2050 in terms individual country growth rates between now and then. Japan, Russia, and countries in Eastern Europe are set to grow more slowly than anywhere else, and some of that group will actually shrink by 10 to 20 percent of their current size. Western, Central, and Eastern Africa will be home to the highest increases. Niger’s 2050 population is expected to be 340 percent its 2011 size – the largest growth of any country.
The map is based on country-level data pulled from a number of sources: the UN Population Division’s latest “World Population Prospects,” the UN Statistics Division’s “Demographic Yearbook 2008,” the U.S. Census Bureau’s International Database, and PRB’s own estimates. It’s unclear what numbers come from which sources, though it is clear that PRB’s 2050 estimates span the UN’s range of medium, high, and constant-fertility variants. In spite of these variations, none of PRB’s estimates come anywhere near the UN Population Division’s low variant estimates.
PRB’s map, echoing its 2011 World Population Data Sheet, shows a world where sub-Saharan Africa will bear the brunt of population growth. The average country in Africa in 2050 is projected to be slightly more than twice its 2011 size; the average European country is expected to barely break even. Africa is home to more countries whose populations are estimated to least double (34) or triple (4) than any other continent. Europe, meanwhile, is home to more countries whose populations will stagnate (8), or even shrink (19), than anywhere else. Interestingly, the Caribbean is a close second in terms of countries whose populations are projected to stay the same (seven to Europe’s eight), and Asia is second to Europe in terms of countries whose populations are projected to shrink (Georgia, Japan, Armenia, South Korea, and Taiwan).
More People, More Climate Change, More Vulnerability
Samson’s map takes on the same time period but projects where people will be most vulnerable to the effects of climate change. Since his map takes into account population growth (measuring where people are most vulnerable, remember), unsurprisingly, Africa, the Middle East, Southeast Asia, and central South America are covered in bright red dots, indicating high vulnerability. Conversely, North America, Europe, and much of Central Asia are in shades of blue.Samson built his index using four environmental predictors – annual mean temperature, mean temperature diurnal range, total annual precipitation, and precipitation seasonality – taken from WorldClim’s 2050 forecasts, and 2005 sub-national population data from Columbia’s Center for International Earth Science Information Network. In spite of the sub-national population data, Samson makes a point to justify his use of supranational climate data in order to best reflect “the scale at which climate conditions vary.” He writes that localized issues like urbanization and coastal flooding “are probably best investigated with targeted regional models rather than by attempting to modify global models to include all factors of potential regional importance.”
Samson’s research shows that, generally, people living in places that are already hot will be more vulnerable to climate change over time, while people in more temperate climates will feel a negligible impact. Though he projects the largest real temperature changes will happen in temperate climates like North America and Europe, the comparatively smaller changes in Africa, the Middle East, Southeast Asia, and central South America are expected to have a greater impact because those regions are already very hot, their natural resources are stressed, and they are expected to bear the brunt of population growth over the next few decades.
These findings reflect a disparity between those responsible for climate change and those bearing the brunt of it, which, although not surprising, “has important implications for climate adaptation and mitigation policies,” said Sampson, discussing the map in a McGill press release.
Sub-National Data “Present a Very Different Picture”
Though they offer a useful approximate glimpse at what the world might look at in 2050, both of these maps fall prey to over-aggregation. By looking at national rather than sub-national data, we miss how nuanced population growth rates can be within a country. Stimson Center Demographer-in-Residence Richard Cincotta wrote in a recent New Security Beat post that “national level comparisons of total fertility rates tend to communicate the false impression of a world with demographically homogeneous states.” Sub-national data, including differences between urban and rural areas and minority-majority fertility rates, “present a very different picture.”
And that difference matters. When it comes to looking at how population interacts with other issues, like the environment, poverty, and conflict, the importance of a sub-national approach becomes evident. In its 2011 data sheet, PRB writes that “poverty has emerged as a serious global issue, particularly because the most rapid population growth is occurring in the world’s poorest countries and, within many countries, in the poorest states and provinces.”Edward Carr, an assistant geography professor at the University of South Carolina currently serving as a AAAS science fellow with USAID, argues that national-level data obscures our ability to understand food insecurity as well. The factors that drive insecurity “tend to be determined locally,” writes Carr in a post on his blog, and “you cannot aggregate [those factors] at the national level and get a meaningful understanding of food insecurity – and certainly not actionable information.”
The same is true when it comes to climate vulnerability. In a report from The Robert S. Strauss Center’s Climate Change and African Political Stability Program, authors Joshua Busby, Todd Smith, and Kaiba White write that “research announcing that ‘Africa is vulnerable to climate change,’ or even ‘Ethiopia is vulnerable,’ without explaining which parts of Ethiopia are particularly vulnerable and why, is of limited value to the international policy community.”
“It is of even less use to Africans themselves, in helping them prioritize scarce resources,” add Busby et al.
Understanding the joint problems of climate change and population growth on a global level helps frame the challenges facing the world as it moves toward 8, 9, and possibly 10 billion. But knowing the ins and outs of how these issues interact on a local level will be a necessary step before policymakers and others can hope to craft meaningful responses that minimize our vulnerability to these challenges over the coming decades.

Broadening Development’s Impact: From Sustainability to Governance and Security
›John Drexhage and Deborah Murphy’s UN background paper, “Sustainable Development: From Brundtland to Rio 2012,” looks at how “sustainable development” has evolved since the 1987 Brundtland Report first brought the concept to the forefront of the international community’s attention. Drexage and Murphy write that climate change has become a “de facto proxy” for sustainable development and they offer various recommendations for how policymakers and institutions can better integrate social and economic issues into a sustainable development framework. Considering that “increasing consumption, combined with population growth, mean that humanity’s demands on the planet have more than doubled over the past 45 years,” the authors conclude that “the opportunity is ripe” to bring “real systemic change” to how the world thinks about – and acts on – sustainable development.The World Bank’s World Development Report 2011 makes an argument for “bringing security and development together to put down roots deep enough to break the cycles of fragility and conflict.” The report gives an overview of the “interconnections among security, governance, and development” and offers recommendations on how understanding and addressing them can end cycles of violence. Just as Drexhage and Murphy point to population changes as a challenge for sustainable development, the World Bank notes that growing urbanization has “increased the potential for crime, social tension, communal violence, and political instability” locally while a threefold increase in refugees and internally displaced persons over the past 30 years has put strains on regional relations around the world. Though the report acknowledges that there’s no quick fix to any of these problems, the conclusion underlining the report’s findings is that “strengthening legitimate institutions and governance to provide citizen security, justice, and jobs is crucial to break cycles of violence.” -
Perfect Storm? Population Pressures, Natural Resource Constraints, and Climate Change in Bangladesh
›Few nations are more at risk from climate change’s destructive effects than Bangladesh, a low-lying, lower-riparian, populous, impoverished, and natural disaster-prone nation. The UN Intergovernmental Panel on Climate Change estimates that by 2050, sea levels in Bangladesh will have risen by two to three feet, obliterating a fifth of the country’s landmass and displacing at least 20 million people. On September 19, the Wilson Center’s Asia Program, with assistance from ECSP and the Comparative Urban Studies Project, hosted a conference that examined Bangladesh’s imperiled environmental security.
Climate Change and PopulationThe first panel focused on manifestations, drivers, and risks. Ali Riaz addressed the threat of climate refugees. Environmental stress, he said, may produce two possible responses: fight (civil conflict or external aggression) or flight (migration). In Bangladesh, the latter is the more likely outcome. Coastal communities, overwhelmed by rising sea levels and flooding, could migrate to Bangladesh’s urban areas or into neighboring India. Both scenarios pose challenges for the state, which already struggles to provide services to its urban masses and has shaky relations with New Delhi.
Mohamed Khalequzzaman examined Bangladesh’s geological vulnerability in the context of climate change. In a deltaic nation like Bangladesh, he explained, sedimentation levels must keep up with rates of sea level rise to prevent the nation from drowning. However, sediment levels now fall below 5 millimeters (mm) per year – short of the 6.5 mm Khalequzzaman calculates are necessary to keep pace with projected sea level rises. He lamented the nation’s tendency to construct large dams and embankments in the Bengal Delta, which “isolate coastal ecosystems from natural sedimentation,” he said, and result in lower land elevations relative to rising sea levels.
Adnan Morshed declared that Bangladesh’s geographic center – not its southern, flood-prone coastal regions – constitutes the nation’s chief climate change threat. Here, Dhaka’s urbanization is “destroying” Bangladesh’s environment, he said. Impelled by immense population growth (2,200 people enter Dhaka each day) and the need for land, people are occupying “vital wetlands” and rivers on the city’s eastern and western peripheries. “Manhattan-style” urban grid patterns now dominate wetlands and several rivers have become converted into land. Exacerbating this urbanization-driven environmental stress are highly polluting wetlands-based brickfields (necessary to satisfy Dhaka’s construction needs) and city vehicular gas emissions.
Adaptation Responses
The second panel considered possible responses to Bangladesh’s environmental security challenges. Roger-Mark De Souza trumpeted the imperative of more gender-inclusive policies. Environmental insecurity affects women and girls disproportionately, he said. When Bangladesh is stricken by floods, females must work harder to secure drinking water and to tend to the ill; they must often take off from school; and they face a heightened risk of sexual exploitation – due, in great part, to the lack of separate facilities for women in cyclone shelters. He reported that such conditions have often led to early forced marriages after cyclones.
Shamarukh Mohiuddin discussed possible U.S. responses. On the whole, American funding for global climate change adaptation programs has lagged and initiatives that are funded often focus more on short-term mitigation (such as emissions reductions) rather than adaptation. She recommended that Washington’s Bangladesh-based adaptation efforts be better coordinated with those of other donors.
Mohiuddin also suggested that to convey a greater sense of urgency, Bangladesh’s climate change threats should be more explicitly linked to national security – and particularly to how America’s strategic ally, India, would be affected by climate refugees fleeing Bangladesh.Philip J. DeCosse highlighted Bangladeshi government success stories in the famed Sundarbans – one of the world’s largest mangrove forests. Officials have banned commercial harvesting in some areas of the forests and shut down a highly polluting paper mill. He also praised civil society and the media for bringing attention to the Sundarban’s environmental vulnerability. As a result of efforts such as these, the Sundarbans are “coming back,” he said, with mangrove species growing anew. Thanks to a range of actors – from the forestry department to civil society – these forests are also now being “governed more than managed,” said DeCosse.

DeCosse’s fellow panelists identified additional hopeful signs. Morshed shared a photograph of a green, pristine park in Dhaka. De Souza underscored how family planning programs have worked in Bangladesh in the past, with fertility rates declining considerably in recent years, and several speakers spotlighted efforts by civil society and the media to bring greater attention to Bangladesh’s environmental security imperatives.
Nonetheless, major challenges remain, and panelists offered a panoply of recommendations. Khalequzzaman called for a major geological study of soil loss and siltation. De Souza implored Bangladesh to ensure that women’s roles and family planning considerations are featured in climate change negotiations and adaptation policies. Morshed advocated for imposing urban growth boundaries and enhancing public transport in cities. And several speakers spoke of the need to pursue more effective natural-resource-sharing arrangements with India. Ultimately, in the words of De Souza, it may not be possible to eliminate Bangladesh’s “perfect storm” – but much can be done to calm it.
