Dividend or Deficit? The Economic Effects of Population Age Structure
›According to the latest projections, the global population will hit the seven billion mark later this year and perhaps nine billion by 2050. Yet, while the global population is growing, it is also aging, due to falling fertility rates and longer life expectancies. By 2050 the number of people aged 60 and over will reach two billion. At an event at the Wilson Center on April 1, Andrew Mason of the University of Hawaii at Manoa and the East-West Center and Ronald Lee of the University of California, Berkeley, discussed their research on the economic effects of an aging world with discussant Dalmer Hoskins of the Social Security Administration. [Video Below]
Changing Age Structures and Economic LifecyclesThere are three phases of age transition, Mason explained: during the first phase, high fertility rates and declining infant and child mortality rates increase the share of children in the population. In the second phase, the proportion of the working age population (those aged 15-64) increases, potentially providing a boost to production and consumption, and in the third phase, the elderly proportion increases due to lower fertility rates, decreasing production and increasing the burden on state support systems.
From 2010-2015, 85 countries are projected to witness the largest absolute increase in history of their populations aged 60 and over. This increase in elder populations is significant, Mason said, because it may mean slower economic growth.
Based on data collected through National Transfer Accounts, Mason and Lee’s economic lifecycle tracks the labor income and consumption rates of a population at a given age. In high income countries, consumption increases around the teen years as a result of investments in education, then dips slightly, and, finally, sharply rises around the age of 80 due to high health care expenditures. The consumption rate remains relatively flat in low income countries, with consumption differing the most in the older ages.
The support ratio measures the number of workers relative to the number of consumers, while taking into account age-specific variances in number of hours worked and level of consumption. Mason explained that China, after four decades of rapid growth, has reached the peak of its support ratio, with many workers relative to the number of consumers. However, China is rapidly aging, like much of Northeast Asia, and also because of its one-child policy. The resulting decline in its support ratio will likely limit its economic growth; however, Mason cautioned that it would be “rash” to say that its growth will bottom out completely.
The United States has an age structure that is “quite a bit more favorable” than other industrial countries, Mason said. Higher fertility, lower life expectancy, and a higher rate of immigration mean that aging is coming more slowly to the United States than other developed countries.
The Second Demographic Dividend: An Investment OpportunityDuring the first demographic dividend, the labor force grows more rapidly than the dependent population, thus allowing more resources to be spent on economic growth. But what happens after that? As populations age, there is a “semi-automatic” increase in investment in human, physical, or financial capital, Lee explained; for example, as fertility falls, the amount invested per child increases. This second demographic dividend, said Lee, can help somewhat offset the decline in support ratio that comes in the third phase of the age transition – aging.
One response to the increased costs of an aging population, said Lee, is to reduce consumption in proportion to the decline in the support ratio. Another option would be adding more hours to the work day or pushing the retirement age back. In the United States, Lee said that to offset the declining support ratio entirely by postponing retirement would require postponement by eight years up to 2050, and 10 years by 2085.
Brazil, Lee said, is the “world champion” of pension generosity, where pensions make up 12 percent of the GDP. The United States, by contrast, relies on asset income from physical or financial investments for about two-thirds of its retirement income. Brazil’s challenge, when it begins to feel the effects of aging (it is still relatively young), will therefore be much greater than in the United States.
A “New Lens” on Aging
Aging, Hoskins said, is not the “catastrophe” that it has been portrayed to be in the media. Supporting an aging population is “something we can plan for and handle,” he said. It is possible “to do the right thing to make sure citizens have a decent life.” The problems come when a country waits too long or does not plan at all, such as in Nigeria and the Philippines where, Hoskins said, they have very underdeveloped social protection systems and the elderly have little to no income. Mason and Lee’s analysis of the work/consumption ratio, said Hoskins, offers a “new lens” into how the world will deal with aging.

UK Helping to Relieve Climate-Related Stress on China’s Agriculture
›The UK and China have been working together since 2001 to better understand how China is going to be impacted by climate change, particularly in the agriculture sector. But understanding must also lead to action, with adaptation needing to be integrated into the development process at both national and local levels. This work, which is ongoing, will increasingly provide a model for how to approach adaptation in other countries.
In my opinion, this work has also contributed to the realization among top-level Chinese officials that it is important to take global action on climate change as part of the international negotiation process; until very recently, most of the international engagement with China has focused on mitigation, with the result that the very real and urgent challenges that China faces in regards to its own adaptation needs have been sidelined.
Another Stressor for Chinese Agriculture
China’s Polices and Actions for Addressing Climate Change, issued in October 2008, state:The impacts of future climate change on agriculture and livestock industry will be mainly adverse. It is likely there will be a drop in the yield of three major crops — wheat, rice and corn; …enlarged scope of crop diseases and insect outbreaks; [and] increased desertification.
Even though assessing the likely impacts of climate change on crop yields is a complicated process, with some evidence showing that in some areas crops may benefit if agricultural technology can keep pace, the overall picture is grim for China.
Potential climate impacts are very worrying for a country which already faces so many other challenges within the agricultural sector, among them the facts that it has to feed nearly one quarter of the world’s population (1.3 billion people) with only seven percent of the world’s arable land; that it has only one-quarter of the world’s average per capita water distribution (one-tenth in large parts of northern China, which are heavily dependent upon agriculture); and that the agricultural land base is fast diminishing due to urbanization, industrialization, and the conversion of arable land to grasslands and forest.
Collaboration on Adaptation
Much of the evidence that supports the understanding of the likely adverse impacts on Chinese agriculture from climate change stems from collaborative work between the UK and China which started in 2001. A joint project, Impacts of Climate Change on Chinese Agriculture (ICCCA), has combined cutting-edge scientific research with practical development policy advice. Although national in scope, the project included pilot work to develop a stakeholder based approach to adaptation in the Ningxia region of northcentral China. ICCCA was successfully completed in December 2008. The UK-China collaboration is now continuing with a major new project which is going beyond agriculture and looking at additional socioeconomic sectors and geographic areas.

Book Launch: ‘The Future Faces of War: Population and National Security,’ by Jennifer Dabbs Sciubba
›“Demographic trends by themselves are neither inherently good nor bad. It’s really a state’s ability to address these issues that can determine the outcome,” said Jennifer Dabbs Sciubba, the Mellon Environmental Fellow with the Department of International Studies at Rhodes College. At a book launch event at the Wilson Center on March 14 for The Future Faces of War: Population and National Security, Sciubba, along with Deputy Under Secretary Kathleen Hicks of the Department of Defense, discussed the national security implications of demography and its important role in understanding and managing conflicts around the world. [Video Below]
Demography as an Indicator, Multiplier, and Resource
Demography can be thought of in three ways, explained Sciubba: as “an indicator of challenge and opportunity; a multiplier of conflict and progress; and a resource for power and prosperity.”
A country’s age structure can pose a challenge, said Sciubba, because countries with a large percentage of their population under the age of 30 “are about two and a half times more likely to experience civil conflict than states with more mature age structures.” Tunisia’s recent revolution, she said, could be understood as a “story about demography.”
The 26-year-old fruit vendor Mohammed Bouazizi, who set himself on fire on December 17 after being hassled by police, was part of one of the largest age cohorts in Tunisia, those aged 25-29. There are some 64 million young men across the Middle East-North Africa region between the ages of 15 and 30, according to UN estimates. “If his death was the spark” for the unrest in the region, Sciubba said, “it’s the underlying demographic trends that were the fodder.”
Yet, Sciubba sees opportunity within this challenge. Citing the work of Richard Cincotta, she said that “states have half a chance – literally 50 percent – of becoming a democracy once their proportion of youth declines to less than 40 percent.” Tunisia has the best chance in the region of becoming a free democracy based on its demography, followed by Libya, where youth aged 15-29 are 43 percent of the adult population.
At the other end of the age structure, some of the world’s most powerful countries, such as Japan, Germany, Italy, France, Russia, and China, are rapidly aging. This aging will “somewhat decrease the ability of these states to project political, economic, and military power” due to a shortage of labor and a smaller pool of funding, said Sciubba.
Countries with transitional age structures, such as India, Brazil, and South Africa, face different security challenges. With a majority of their populations between 15 and 60 years old, there are more people contributing to the economy than are taking away, which could bolster these countries economically and politically (the “demographic dividend”). Global institutions will have to reform and include these countries, she advised, “or else become irrelevant.”
But the defining trend of the 21st century, said Sciubba, is urbanization. While great sources of economic growth, cities are also quite vulnerable to natural disasters and terrorism because of their concentrations of people, wealth, infrastructure, and bureaucracy.
In looking to the future, Sciubba called for continued support for family planning initiatives. “At least 90 percent of future world population growth will take place in less developed countries,” which are least equipped to handle the demands of that growth, she said. In addition, Sciubba recommended that the United States seek out partnerships with countries that have transitional age structures, particularly India, which could be a stabilizing force in a tumultuous region. She also called on the United States to partner with states in the Western Hemisphere and remain open to migration.
Defense and Demography
“Understanding population is critical to our success in being able to prevent conflict, and also managing conflict and crises once we’re involved,” said Hicks, describing the Department of Defense’s (DOD) interest in demography. However, the DOD does not “treat demographics as destiny,” she said, but instead as “one of several key trends, the complex interplay of which may spark or exacerbate future conflicts.”
Recent world events, such as those in the Middle East and North Africa, “have demonstrated how critical our understanding of population is for security practitioners,” said Hicks. Similarly, the recent earthquake and tsunami in Japan dramatically illustrate the vulnerability of large urban areas. Echoing Sciubba’s comments on population aging, she cited “incredible divestments in defense” in Europe, which, she said, “puts us, as a key partner in NATO, at a thinking stage.”
Under Secretary of Defense for Policy Michèle Flournoy is “deeply interested” in demographic issues, said Hicks. She identified other demographic areas of great interest for her office: the youth bulge in Pakistan, urbanization in Afghanistan, the role of highly educated women in Saudi Arabia, the Chinese diaspora in the Americas, Russia’s shrinking population, and various trends in China, including aging, gender imbalance, urbanization, and migration.

China’s Green Five-Year Plan: Making “Ecological Security” a National Strategy
›March 16, 2011 // By Wilson Center StaffThe original version of this article, by Hu Angang and Liang Jiaochen, appeared on ChinaDialogue.
Five-year plans (FYPs), which set down and clarify national strategy, are one of China’s most important policy tools. Just as they have helped to drive China’s economic success over recent decades, so they will play a pivotal role in putting the country on a green development path. The 12th Five-Year Plan, now under consideration by the National People’s Congress, marks the beginning of that process in earnest (Editor’s note: Since this was originally published, the National People’s Congress voted in favor of the plan).
FYPs embody the concept of progressing by degrees, or developing step by step. This approach has been one of the driving forces behind China’s economic progress in recent decades and will now provide the platform for its green development. It is the methodology underpinning China’s socialist modernization: to reach a new step in development every five years. Unstinting efforts over a number of FYPs have driven China’s transformation.
Climate change presents a long-term and all-encompassing challenge for China. It demands a long-term development strategy and broad goals, as well as near-term action plans and concrete policies. Combining these is precisely the idea behind FYPs.
At the global climate change summit in Copenhagen in 2009, China demonstrated it has the long-term political will to respond to climate change; to work with the world to limit global temperatures to no more than two degrees Celsius above pre-industrial temperatures (the goal set out in the Copenhagen Accord). In November that year, the Chinese government formally put forward its medium-term targets on climate change: a reduction in energy intensity of 40 percent to 45 percent on 2005 levels by 2020, and generation of 15 percent of energy from non-fossil fuel sources by the same date.

Choke Point China: Escalating Confrontation Between Water Scarcity and Energy Demand Has Global Implications
›The original version of this article, by J. Carl Ganter, appeared on The Huffington Post. Visit Circle of Blue for the latest articles in the Choke Point: China series.
Water scarcity, rapid economic growth, and soaring energy demand are forming a tightening noose that could choke off China’s modernization.
Writes my colleague Keith Schneider in the first installment of the new report, Choke Point: China, from Circle of Blue:Underlying China’s new standing in the world, like a tectonic fault line, is an increasingly fierce competition between energy and water that threatens to upend China’s progress. Simply put, say Chinese authorities and government reports, China’s demand for energy, particularly for coal, is outpacing its freshwater supply.
The 12-part Choke Point: China series presents powerful evidence of the fierce contest between growth, water, and fuel that is virtually certain to grow more dire over the next decade. The project is produced in partnership with the Woodrow Wilson International Center for Scholars’ China Environment Forum.
Tight supplies of fresh water are nothing new in a nation where 80 percent of the rainfall and snowmelt occurs in the south, while just 20 percent of the moisture occurs in the mostly desert regions of the north and west. What’s new is that China’s surging economic growth is prompting the expanding industrial sector, which consumes 70 percent of the nation’s energy, to call on the government to tap new energy supplies, particularly the enormous reserves of coal in the dry north.
The problem, scholars and government officials told us, is that there is not enough water to mine, process, and consume those reserves and still develop the modern cities and manufacturing centers that China envisions for the region. “Water shortage is the most important challenge to China right now, the biggest problem for future growth,” said Wang Yahua, deputy director of the Center for China Study at Tsinghua University in Beijing. “It’s a puzzle that the country has to solve.”
The consequences of diminishing water reserves and rising energy demand have been a special focus of our attention for more than a year. In 2010, in our “Choke Point: U.S.” series, Circle of Blue found that rising energy demand and diminishing freshwater reserves are two trends moving in opposing directions across America. Moreover, the speed and force of the confrontation is occurring in the places where growth is highest and water resources are under the most stress – California, the Southwest, the Rocky Mountain West, and the Southeast.
Stripped to its essence, China’s globally significant choke point is caused by three converging trends:- Production and consumption of coal – the largest industrial consumer of water – has tripled since 2000. Government analysts project that China’s energy companies will need to increase coal production by 30 percent by 2020.
- Fresh water needed for mining, processing, and consuming coal accounts for the largest share of China’s industrial water use, a fifth of all the water consumed nationally. Though national conservation policies have helped to limit increases, water consumption nevertheless has climbed to record highs.
- China’s total water resource, according to the National Bureau of Statistics, has dropped 13 percent since the start of the century. In other words China’s water supply is 350 billion cubic meters (93 trillion gallons) less than it was at the start of the century. That’s as much water lost to China each year as flows through the mouth of the Mississippi River in nine months. Chinese climatologists and hydrologists attribute much of the drop to climate change, which is disrupting patterns of rain and snowfall.
We found a powerful narrative in China in two parts, and never before told: First is how effectively the national and provincial governments enacted and enforced a range of water conservation and efficiency measures that enabled China to progress as far as it has.
Second is that despite the extensive efforts to conserve water, and to develop water-sipping alternatives like wind and solar energy, China still faces an enormous projected shortfall of water this decade to its energy-rich northern and western provinces. How government and industry leaders respond to this critical and unyielding choke point forms the central story line of the next era of China’s unfolding development.

Demographic Trends and Policy Implications in Northeast Asia
›Japan, the People’s Republic of China, Taiwan, and Korea are all aging societies. On February 26, the Wilson Center’s Asia Program hosted an event to consider issues related to demographic change in Northeast Asia. What will be the effect of aging on economic output in these countries? Can welfare states established for much younger populations in developed economies survive the stress of demographic change, or will governments in Northeast Asia need to radically rethink the provision of care to the elderly? Can immigration reform alleviate many of the problems associated with more elderly populations in Northeast Asia? And will current demographic shifts foster more benign or more belligerent interstate relations in the region?
At the event, Harvard University School of Public Health research associate Jocelyn Finlay noted that demographic trends are often overlooked in explaining economic growth in Japan, South Korea, and Taiwan between 1960 and 2000. Demographers estimate that decreases in infant mortality and adult fertility levels, which resulted in an increase of workers relative to dependents, accounted for up to a third of economic growth in these countries during this period. As the age cohort born after 1945 enters into retirement, however, the increase in dependents relative to new workers will be a contributing factor to sluggish growth. Finlay mentioned that pro-natalism and pro-immigration policies, and policies that encourage women and the elderly to participate in the workplace, could help to mitigate the effects of an aging society on economic growth but noted that such policies were all difficult to implement.
These difficulties were examined in further detail by Ito Peng, professor of sociology at the University of Toronto. Peng noted that East Asian democracies have traditionally maintained very lean welfare states, relying instead on private institutions such as extended families to carry much of the burden of, for example, care for the elderly. However, public provision of care for the aged is increasing in these countries, where the nuclear family has become the norm. Governments must actively pursue strategies to increase the number of workers and therefore income tax revenues to pay for the resulting increases in public spending.
However, policies intended to expand the tax base often have unintended consequences. For example, encouraging people to have larger families often has the effect of forcing mothers to stay at home to care for their children, depriving the labor force of a productive worker in the short term. To address this problem, Japan and South Korea have increased the level of public childcare provision. However Peng believes that there needs to be greater integration between the private and public spheres to make Northeast Asian workplaces, still a sphere of male dominance, friendlier to working mothers. Companies that insist on significant overtime duties could, for example, find ways to let working parents maintain a work-life balance that allows them to personally care for their children. Northeast Asian countries can also institute pro-immigration policies to bring more young workers from abroad. However, sustained immigration policies are also difficult in nations, like Japan and South Korea, without a history of accepting newcomers.
For Richard Cincotta, demographer-in-residence at the Stimson Center and consultant for the Wilson Center’s Environmental Change and Security Program, demographic change will be a major factor in determining the way states in Northeast Asia approach security. To illustrate the relationship between demography and security, Cincotta noted that Japan’s militarist period in the 1930s and 1940s occurred when its population was younger, more ambitious, and more energetic. With older societies, countries in Northeast Asia will be able to recruit fewer males for the military, meaning their foreign policies may shift more towards caution.
The exception, however, is China, where the number of potential male recruits far outnumbers those of its neighbors. This means that Japan, South Korea, and Taiwan will come under more pressure to intensify the use of human capital by promoting more professionalized and better equipped militaries. They will also have incentives to resolve any differences with their key ally, the United States, as well as among each other. Cincotta suggested that we may be seeing the start of a new type of Cold War, where Pacific Northeast Asian states cooperate to check a potential Chinese regional hegemon.

China’s Biggest Environmental Stories of 2010/11
›January 21, 2011 // By Wilson Center StaffThe original version of this post first appeared on ChinaDialogue’s The Daily Planet blog, December 23, 2010.
Last month I spent a few days in Washington, DC meeting mostly with people working on U.S.-China environmental relations. Among others, I met with Jennifer Turner, director of the China Environment Forum at the Wilson Center (and my former boss), and we had an exciting conversation about the biggest China environmental stories covered in the United States in 2010, and what we hope to see in 2011. I was inspired to write this post based on our conversation. This is of course neither definitive nor exhaustive, but merely my perspective on how things look from Washington.China Is Winning the Clean Energy Race. Energy was the big story in 2010. Studies show that the United States will need to renovate or retire virtually all of its power plants by 2050, and China must build a modern energy sector to serve a growing population. Both countries emphasized their intentions to build a clean energy economy in 2010 and almost immediately competition was dubbed a “race.” Soon after it was declared a two-party race, it became evident that China was winning.
China’s clean energy investment is two times greater than that of the United States, according to a Pew Charitable Trust report published last year. The news has centered upon China’s ability to make sweeping changes to domestic energy markets, in stark contrast to the United States’ inability to pass climate legislation. Most notably in 2010, China passed a regulation requiring that a percentage of all electric company profits be used for energy efficiency every year.
Energy “Co-op-etion.” Perhaps as a response to fears of “losing” the energy race, public opinion in the United States focused on new and existing energy cooperation and on market fairness. The U.S.-China Clean Energy Research Center, signed in 2009, was officially launched in 2010 and is likely to formalize a great deal of on-going cooperation on energy between the United States and China. In December, Jonathan Silver, Executive Director of the U.S. Department of Energy’s Loan Guarantee Program, spoke at a conference in San Francisco and described the developing energy relationship between China and the United States as “co-op-etition” – the two countries have complementary markets and a lot to learn from each other but will compete in U.S., Chinese, and international markets to sell clean technologies.
Concerns about the fairness of the market – initially because of changes in China’s government procurement laws discriminating against foreign clean technology companies – peaked with the U.S. Steel Workers’ petition in October. Americans are concerned that their technologies will suffer in the international market because of Chinese clean technology subsidies.
China “Ruined” Copenhagen. Perception that China ruined Copenhagen dominated the U.S. news early in the year but was softened by a more positive outlook following Cancun. Anxiety in Washington, DC regarding the accuracy of China’s CO2 data colored many debates on American participation in international climate negotiations all year.
Oil and Rare Earths. The oil spill in Dalian in July made big news in the United States as it came in the wake of the BP oil spill in the Gulf of Mexico. Many comparisons were made, despite the enormous difference in scale between the two incidents. Rare earth elements (the spine of the clean technology industry) were another major concern that arose in 2010 in Washington. Many of America’s rare earth mines were shuttered decades ago when Chinese mines were able to produce more affordably. This year, China began restricting rare earth exports, at least partially for environmental reasons, forcing the United States to consider reopening many of its mines and how to deal domestically with the environmental effects of those mines.
In 2011 I hope that interest in China’s environment will continue in the United States, but I expect that we will see less on renewables, as stimulus money runs thin, and rising concern for more traditional pollutants and basic environmental governance in China (especially regarding water and air pollutants).
The 12th Five-Year Plan. Set to be released early 2011, the 12 Five-Year Plan will initially dominate energy stories as it outlines how China will meet its ambitious energy intensity targets. I expect nuclear energy will replace wind and solar as the big stories in 2011. Nuclear liability should be addressed in China in 2011, as it was in India in 2010. Because of the close energy business ties between China and the United States, liability laws in China are likely to be more sympathetic to the needs of American companies than India’s recent law, which exposes nuclear components suppliers to unlimited liability.
Soil Pollution Prevention and Remediation. China’s soil pollution survey was completed in 2009 and the draft Provisional Rules on Environmental Management of the Soil of Contaminated Sites was released by the Ministry of Environmental Protection for comment in December 2009. The problem is huge and significant in China’s development and construction boom, and little data has been publicly released from the survey. I expect that in 2011, we will start to see active management and enforcement, at least in major cities.
Water Quality and Quantity. Water has and will likely continue to be, the greatest environmental concern in China and abroad, given its transboundary nature. Turner suggests we will see more on control of and attention to nitrogen pollution in China’s waterways in 2011.
To chime in with your comments on what you feel were the biggest stories of 2010 and what you predict will dominate 2011, be sure to let us know below or on ChinaDialogue.

Elizabeth Malone on Climate Change and Glacial Melt in High Asia
›“There’s nothing more iconic, I think, about the climate change issue than glaciers,” says Elizabeth Malone, senior research scientist at the Joint Global Change Research Institute and Pacific Northwest National Laboratory. Malone served as the technical lead on “Changing Glaciers and Hydrology in Asia: Addressing Vulnerability to Glacier Melt Impacts,” a USAID report released in late 2010 that explores the linkages between climate change, demographic change, and glacier melt in the Himalayas and other nearby mountain systems.
Describing glaciers as “transboundary in the largest sense,” Malone points out that meltwater from High Asian glaciers feeds many of the region’s largest rivers, including the Indus, Ganges, Tsangpo-Brahmaputra, and Mekong. While glacial melt does not necessarily constitute a large percentage of those rivers’ downstream flow volume, concern persists that continued rapid glacial melt induced by climate change could eventually impact water availability and food security in densely populated areas of South and East Asia.
Rapid demographic change has potentially factored into accelerated glacial melt, even though the connection may not be a direct one, Malone adds.
Atmospheric pollution generated by growing populations contributes to global warming, while black carbon emissions from cooking and home heating can eventually settle on glacial ice fields, accelerating melt rates. Given such cause-and-effect relationships, Malone says that rapid population growth and the continued retreat of High Asian glaciers are “two problems that seem distant,” yet “are indeed very related.”
