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.

Rwanda: Dramatic Uptake in Contraceptive Use Spurs Unprecedented Fertility Decline
›November 8, 2011 // By Elizabeth Leahy MadsenWith over 400 people per square kilometer, the highest rate on the African mainland, population density is perhaps the most widely-discussed factor of Rwanda’s demography. Some scholars, notably Jared Diamond, have argued that it played a primary role in sparking the 1994 genocide through competition for land (although others present a more complex theory based in policies and governance).

Michael Kugelman for Seminar
Safeguarding South Asia’s Water Security
›November 4, 2011 // By Wilson Center StaffThe original version of this article, by Michael Kugelman, appeared in the public policy journal Seminar.
In today’s era of globalization, the line between critic and hypocrite is increasingly becoming blurred. Single out a problem in a region or country other than one’s own, and risk triggering an immediate, yet understandable, response: Why criticize the problem here, when you face the same one back home?
Such a response is particularly justified in the context of water insecurity, a dilemma that afflicts scores of countries, including the author’s United States. In the parched American West, New Mexico has only 10 years-worth of drinking water remaining, while Arizona already imports every drop. Less arid areas of the country are increasingly water-stressed as well. Rivers in South Carolina and Massachusetts, lakes in Florida and Georgia, and even the mighty Lake Superior (the world’s largest fresh-water lake) are all running dry. According to the U.S. Environmental Protection Agency, if American water consumption habits continue unchecked, as many as 36 states will face water shortages within the next few years. Also notable is the fact that America’s waterways are choked with pollution, and that nearly twenty million Americans may fall ill each year from contaminated water. Not to mention that more than thirty U.S. states are fighting with their neighbors over water.
Such a narrative is a familiar one, because it also applies to South Asia. However, in South Asia, the narrative is considerably more urgent. The region houses a quarter of the world’s population, yet contains less than five percent of its annual renewable water resources. With the exception of Bhutan and Nepal, South Asia’s per capita water availability falls below the world average. Annual water availability has plummeted by nearly 70 percent since 1950, and from around 21,000 cubic meters in the 1960s to approximately 8,000 in 2005. If such patterns continue, the region could face “widespread water scarcity” (that is, per capita water availability under 1,000 cubic meters) by 2025. Furthermore, the United Nations, based on a variety of measures – including ecological insecurity, water management problems and resource stress – characterizes two key water basins of South Asia (the Helmand and Indus) as “highly vulnerable.”
These findings are not surprising, given that the region suffers from many drivers of water insecurity: high population growth, vulnerability to climate change, arid weather, agriculture dependent economies, and political tensions. This is not to say that South Asia is devoid of water security stabilizers; indeed, its various trans-national arrangements, to differing degrees, help the region manage its water constraints and tensions. This paper argues that such arrangements are vital, yet also incapable of safeguarding regional water security on their own. It asserts that more attention to demand-side water management within individual countries is as crucial for South Asian water security as are trans-national water mechanisms.

New Report Launched: ‘The World’s Water’, Volume Seven
›“The water problem is real and it is bad,” said MacArthur “Genius” Fellow and founder of the Pacific Institute Peter Gleick at the October 18 launch of the seventh volume the institute’s biennial report on freshwater resources. “It’s not bad everywhere, and it’s not bad in the same way from place to place, but we are not doing what we need to do to address all of the different challenges around water.”
“The World’s Biggest Problem”
Worldwide, more than a billion people lack access to safe drinking water, while two and a half billion lack access to adequate sanitation services. “This is the world’s biggest water problem,” said Gleick, “the failure to meet basic human needs for water – it’s inexcusable.”
Gleick predicts that the world will fail to meet the Millennium Development Goals for water and sanitation by 2015, and noted that measures of illness for water-related diseases are rising, rather than falling.The World’s Water series provides an integrated way of thinking about water by exploring major concepts, important data trends, and case studies that point to policies and strategies for sustainable use of water. Volume seven includes chapters on climate change and transboundary waters, corporate water management, water quality challenges, Australia’s drought, and Chinese and U.S. water policy. The new volume also includes a set of side briefs on the Great Lakes water agreement, the energy required to produce bottled water, and water in the movies, as well as 19 new and updated data tables. An updated water conflict chronology looks at conflicts over access to water, attacks on water, and water used as a weapon during conflict.Peter Gleick on climate change and the water cycle.
Despite the added data, Gleick said that vast gaps remain in our knowledge and understanding about water. We lack accurate information on how much water the world has, where it is, how much humans use, and how much ecosystems need, he said. “So right off the bat, we are at a disadvantage.”
Focus on Efficiency, Infrastructure to Better Manage Water
One of the major concepts that has connected various volumes of The World’s Water is the concept of a “soft path for water” – a strategy for moving towards a more sustainable future for water through several key focus points: improved efficiency, decentralized infrastructure, and broadly rethinking water usage and supply.
Other cross-cutting themes include climate and water, peak water, environmental security, and the human right to water (formally recognized in a 2010 UN General Assembly resolution). “I would argue that all of these combined offer to some degree a different way of thinking about water, an integrated way of thinking about water,” Gleick said.
The China Issue
The role of China has been one of the most significant changes over the course of the series, said Gleick. The growth in the Chinese economy has led to a massive growth in demand for water (see the Wilson Center/Circle of Blue project, Choke Point: China), as well as massive contamination problems. The newest volume addresses these issues as well as China’s dam policies – internally, with neighboring countries, and around the world.
Gleick pointed out that China is one of the only nations (maybe the only) that still has a massive dam construction policy, and their installed capacity is already much larger than the United States, Brazil, or Canada. In addition, Chinese companies and financial interests are involved in at least 220 major dam projects in 50 countries around world. These projects have become increasingly controversial, for both environmental and political reasons, he said.
“My lens is typically a water lens,” Gleick said, but “none of us can think about the problems we really care about, unless we think about a more integrated approach.” Gleick emphasized the need for new thinking about sustainable, scalable, and socially responsible solutions. “We have to do more than we are doing, in every aspect of water,” he concluded.

Seven Ways Seven Billion People Affect the Planet
›October 31, 2011 // By Geoffrey D. DabelkoSeven billion people now live on earth, only a dozen years after global population hit six billion. But the seven billion milestone is not about sheer numbers: Demographic trends will significantly impact the planet’s resources and peoples’ security.
Growing populations stress dwindling natural resource supplies while high levels of consumption in both developed countries and emerging economies drive up carbon emissions and deplete the planet’s resources. And neglected “youth bulges” could bolster extremism in fragile states like Somalia and destabilize nascent democracies like Egypt.
Here are seven ways seven billion people affect the planet, according to recent research:
Security: Nearly 90 percent of countries with very young and youthful populations had undemocratic governments at the end of the 20th century. Eighty percent of all new civil conflicts between 1970 and 2007 occurred in countries where at least 60 percent of the population is under age 30, says demographer Elizabeth Leahy Madsen. According to research by demographer Richard Cincotta, these countries may achieve democracy, but are less likely to sustain it.- Richard Cincotta: Tunisia Predicted: Demography and the Probability of Liberal Democracy in the Greater Middle East
- Elizabeth Leahy Madsen: Demographic Security 101
Water: By 2025, 1.8 billion people will be living in countries with water scarcity, and fully two-thirds will be living in conditions of water stress. People are using groundwater faster than it can be naturally replenished, putting us in danger of “peak water,” says MacArthur “Genius” Fellow Peter Gleick. “We cannot talk about water without also understanding the enormously important role of population dynamics and population growth.”- Peter Gleick: Population Dynamics Key to Sustainable Water Solutions
Forests: The growing demand for energy has helped devastate tropical forests, as more than two billion people depend on wood for cooking and heating, particularly in developing countries. Projects in Indonesia, Nepal, and Uganda are fighting deforestation by providing alternative energy and incomes along with health and family planning services.- Indonesia: Health in Harmony
- Nepal: Forests for the Future
- Uganda: Sharing the Forest
Future Growth: By 2050, the UN says global population could range anywhere from 8 billion to 11 billion – and where it ends up depends in large part on the status of women in developing countries. “Even if fertility rates remain constant at current levels (which is unlikely), developing regions would grow from 5.7 billion in 2010 to 9.7 billion in 2050, but the total population of developed countries would remain essentially unchanged,” writes Madsen.- Elizabeth Leahy Madsen: How Did We Arrive at 7 Billion – and Where Do We Go From Here? [Part One] [Part Two]
There are no quick solutions to these seven problems. But meeting the unmet need for contraception of more than 200 million women is an effective and inexpensive way to start.

Watch: Gidon Bromberg Gives an Update on Jordan River Rehabilitation Efforts
›October 27, 2011 // By Kate DiamondGidon Bromberg, co-director of Friends of the Earth Middle East (FOEME), says in this short interview with ECSP that his outlook on rehabilitating the Jordan River has changed completely over the last five years. We had been “laughed at” for trying to restore the waterway, he said; now though, “we are very confident that the Jordan River south of the Galilee down to the Dead Sea will be rehabilitated.”
By building a cross-border peace park and encouraging collaboration between Israelis, Palestinians, and Jordanians on water scarcity and quality issues, FOEME aims to improve environmental and security problems that bind the three groups together.
The Jordan River has become so polluted that visitors, many of whom are devout Christians making a pilgrimage to one of the religion’s most sacred sites, have been barred from its waters due to health concerns. Furthermore, more than 98 percent of its fresh water is diverted for agricultural work, meaning that the pollutants that end up in the river are highly concentrated.
But today, Bromberg said, sewerage is being removed on both the Israeli and Jordanian sides and there is a commitment to do the same from the Palestinians. For the first time in 60 years, there are concrete plans to return fresh water to a river that is “so holy to half of humanity.”

People and Wildlife Compete in East Africa’s Albertine Rift
›The original version of this article, by Robert Draper, appeared on National Geographic.
The mwami remembers when he was a king of sorts. His judgment was sovereign, his power unassailable. Since 1954 he, like his father and grandfather before him, has been the head of the Bashali chiefdom in the Masisi District, an undulating pastoral region in eastern Democratic Republic of the Congo (DRC). Though his name is Sylvestre Bashali Mokoto, the other chiefs address him as simply doyen – seniormost. For much of his adult life, the mwami received newcomers to his district. They brought him livestock or other gifts. He in turn parceled out land as he saw fit.
Today the chief sits on a dirty couch in a squalid hovel in Goma, a Congolese city several hours south of Masisi. His domain is now the epicenter of a humanitarian crisis that has lasted for more than a decade yet has largely eluded the world’s attention. Eastern Congo has been overtaken by thousands of Tutsi and Hutu and Hunde fighting over what they claim is their lawful property, by militias aiming to acquire land by force, by cattlemen searching for less cluttered pastures, by hordes of refugees from all over this fertile and dangerously overpopulated region of East Africa seeking somewhere, anywhere, to eke out a living. Some years ago a member of a rebel army seized the mwami’s 200-acre estate, forcing him, humiliated and fearing for his safety, to retreat to this shack in Goma.
The city is a hornet’s nest. As recently as two decades ago Goma’s population was perhaps 50,000. Now it is at least 20 times that number. Armed males in uniform stalk its raggedy, unlit streets with no one to answer to. Streaming out of the outlying forests and into the city market is a 24/7 procession of people ferrying immense sacks of charcoal on bicycles or wooden, scooter-like chukudus. North of the city limits seethes Nyiragongo volcano, which last erupted in 2002, when its lava roared through town and wiped out Goma’s commercial district. At the city’s southern edge lies the silver cauldron of Lake Kivu – so choked with carbon dioxide and methane that some scientists predict a gas eruption in the lake could one day kill everyone in and around Goma.
The mwami, like so many far less privileged people, has run out of options. His stare is one of regal aloofness. Yet despite his cuff links and trimmed gray beard, he is not a chief here in Goma. He is only Sylvestre Mokoto, a man swept into the hornet’s nest, with no land left for him to parcel out. As his guest, a journalist from the West, I have brought no gifts, only demeaning questions. “Yes, of course my power has been affected greatly,” the mwami snaps at me. “When others back up their claims with guns, there is nothing I can do.”

Minority Youth Bulges and the Future of Intrastate Conflict
›October 13, 2011 // By Richard CincottaFrom a demographic perspective, the global distribution of intrastate conflicts is not what it used to be. During the latter half of the 20th century, the states with the most youthful populations (median age of 25.0 years or less) were consistently the most at risk of being engaged in civil or ethnoreligious conflict (circumstances where either ethnic or religious factors, or both, come into play). However, this tight relationship has loosened over the past decade, with the propensity of conflict rising significantly for countries with intermediate age structures (median age 25.1 to 35.0 years) and actually dipping for those with youthful age structures (see Figure 1 below).
