“All Consuming:” U of M’s ‘Momentum’ on Population, Health, Environment, and More
›August 23, 2010 // By Schuyler NullMinnesota’s Institute on the Environment is only in its third year of operation but has already established itself as an emerging forum for population, health, and, environment issues, due in no small part to its excellent thrice-a-year publication, Momentum. The journal is not only chock-full of high production values and impressively nuanced stories on today’s global problems, but is also, amazingly, available for free.
Momentum has so far covered issues ranging from food security, gender equity, demographic change, geoengineering, climate change, life without oil, and sustainable development.
Highlights from the latest issue include: “Girl Empower,” by Emily Sohn; “Bomb Squad,” with Paul Ehrlich, Bjørn Lomborg, and Hans Rosling; and “Population Hero,” on the fiscal realities of stabilizing growth rates.
The lead story featured below, “All Consuming,” by David Biello, focuses on the debate over whether consumption or population growth poses a bigger threat to global sustainability.Two German Shepherds kept as pets in Europe or the U.S. use more resources in a year than the average person living in Bangladesh. The world’s richest 500 million people produce half of global carbon dioxide emissions, while the poorest 3 billion emit just 7 percent. Industrial tree-cutting is now responsible for the majority of the 13 million hectares of forest lost to fire or the blade each year — surpassing the smaller-scale footprints of subsistence farmers who leave behind long, narrow swaths of cleared land, so-called “fish bones.”
Continue reading on Momentum.
In fact, urban population growth and agricultural exports drive deforestation more than overall population growth, according to new research from geographer Ruth DeFries of Columbia University and her colleagues. In other words, the increasing urbanization of the developing world — as well as an ongoing increase in consumption in the developed world for products that have an impact on forests, whether furniture, shoe leather, or chicken fed on soy meal — is driving deforestation, rather than containing it as populations leave rural areas to concentrate in booming megalopolises.
So are the world’s environmental ills really a result of the burgeoning number of humans on the planet — growing by more than 150 people a minute and predicted by the United Nations to reach at least 9 billion people by 2050? Or are they more due to the fact that, while human population doubled in the past 50 years, we increased our use of resources fourfold?

‘UK Royal Society: Call for Submissions’ “People and the Planet” Study To Examine Population, Environment, Development Links
›August 12, 2010 // By Wilson Center StaffBy Marie Rumsby of the Royal Society’s In Verba blog.
In the years that followed the Iranian revolution, when Ayatollah Khomeini returned from exile to Tehran and the country went to war against Iraq, the women of Iran were called upon to provide the next generation of soldiers. Following the war the country’s fertility rate fell from an average of over seven children per woman to around 1.7 children per woman – one of the fastest falls in fertility rates recorded over the last 25 years.
Iran is an interesting example but every country has its own story to tell when it comes to population levels and rates of change. The global population is rising and is set to hit 9 billion by 2050. And whilst fertility rates in Ethiopia are on the decline, its total population is projected to double from around 80 million today, to 160 million in 2050.
Earlier this month, the Royal Society announced it is undertaking a new study which will look at the role of global population in sustainable development. “People and the Planet” will investigate how population variables – such as fertility, mortality, ageing, urbanization, and migration – will be affected by economies, environments, societies, and cultures, over the next 40 years and beyond.
The group informing the study is chaired by Nobel Laureate Sir John Sulston FRS, and includes experts from a range of disciplines, from all over the world. With names on the group such as Professor Demissie Habte (President of the Ethiopian Academy of Sciences), Professor Alastair Fitter FRS (Professor Environmental Sciences, University of York) and Professor John Cleland FBA (Professor of Medical Demography, London School of Hygiene and Tropical Medicine), there’s bound to be some lively discussions.
Linked to the announcement of the study, the Society held a PolicyLab with Fred Pearce, environmental journalist, and Jonathon Porritt, co-founder of Forum for the Future, to discuss the significance of population in sustainable development.
Both speakers have been campaigning against over-consumption for many years. Jonathon Porritt has been a keen advocate for fully funded, fully engaged voluntary family planning in every country in the world that wants it.
“In my opinion, that would allow us to stabilize global population at closer to 8 billion, rather than 9 billion. And if we did it seriously for forty years, that is an achievable goal.” Porritt thinks that stabilizing global population at 8 billion rather than 9 billion would save a large number of women’s lives, and suggests “you cannot ignore the gap between 8 billion and 9 billion if you are thinking seriously about climate change.”
Fred Pearce acknowledges that population matters, but stresses that it is consumption (and how we produce what we produce) that we need to focus on. He feels it is too convenient for us to focus on population.
According to Fred, the global average is now 2.6 children per woman – that’s getting close to the global replacement level of 2.3 children per woman.
“It is no longer human numbers that are the main threat……It’s the world’s consumption patterns that we need to fix, not its reproductive habits,” said Pearce.
The Society will be taking a long look at some of these issues, assessing the latest scientific evidence and uncertainty around population levels and rates of change. The “People and the Planet” study is due for publication in early 2012, ahead of the Rio+20 UN Earth Summit. The Society is currently seeking evidence to inform this study from a wide-range of stakeholders.
The deadline for submissions is October 1, 2010. For more information on submissions, please see the Royal Society’s full call for evidence announcement.

Misguided Projections for Africa’s Fertility
›By assuming that sub-Saharan Africa’s total fertility rate will decrease to 2.5 children per woman by 2050, the most recent population projections issued by the Population Reference Bureau likely continue to underestimate fertility for Africa. Though northern Africa has significantly lowered fertility, sub-Saharan Africa’s TFR is still 5 children per woman. Achieving the levels projected by PRB or the United Nations will largely depend on whether the conditions that led to past fertility declines for other states can be established in sub-Saharan Africa.
Demographers have identified numerous factors associated with fertility decline, including increased education for females, shifting from a rural agricultural economy to an industrial one, and introduction of contraceptive technology. Sub-Saharan Africa is only making slow progress in each of these areas.
Surveying Obstacles to Development
Primary school enrollment is up, but the pace of improvement is declining. Meanwhile, gender gaps persist: Enrollment for boys remains significantly higher than for girls. Girls’ education is associated with lower fertility, partly because education helps women take charge of their fertility and also because education influences employment opportunities. Increased female labor force participation has been shown to increase the cost of having children, and is therefore associated with initial fertility declines.
Disease is one wildcard for Africa that limits the utility of past models of demographic transition in the African context. HIV/AIDS is decimating sub-Saharan Africa’s adult workforce and creating shortages of teachers that will impede future efforts to boost primary school enrollment. According to the United Nations, the number of teachers in sub-Saharan Africa needs to double in the next five years to reach Millennium Development goals.
Development that would shift the region’s economies from agriculture to industry is also lagging. While several West African countries are seeing some gains, the African continent on the whole faces major structural impediments to development. In The Bottom Billion, Paul Collier points out that many of these countries may have “missed the boat” to attract investment and industry that would pull the region out of poverty, partly because the least developed countries are still not cost-competitive enough when compared with current centers of manufacturing, like China.
Finally, there remains a high unmet need for family planning. One in four women aged 15 to 49 who are married or in union –- and who have expressed an interest in using contraceptives — still do not have access to family planning tools. In general, maternal mortality remains high and adolescents in the poorest households are three times more likely to become pregnant and give birth than those in the richest households, according to the most recent UN Millennium Development Goals report.
Sub-Saharan Africa: Off the Radar?
Sub-Saharan Africa suffers from a lack of attention by the international community and lack of political capacity at home. Many countries in the region are plagued by civil strife and poor governance, and developed countries continue to fall short of development assistance pledges. There is not the same sense of urgency today among developed countries about the global population explosion as there once was. Cold War politics and the environmental and feminist movements motivated much of the study of fertility and funding of population programs during the second half of the 20th century. Attention by governments and NGOs sped the fertility transition among many countries.
Today, the world’s wealthiest countries are not concerned primarily with Africa’s problems, but rather are more concerned with their own population decline and with the national security implications of population trends in areas associated with religious extremism. The recession has further hindered the flow of development funds.
Fertility is the most difficult population component to predict, and demographers must draw on the experiences of other regions to inform assessments of Africa’s population patterns. Demographers seem to be overconfident that Africa’s fertility will follow the pattern of recent declines, particularly in Latin America, which were more rapid than Western Europe’s decline due to the diffusion of technology and knowledge.
Once states begin the demographic transition towards lower fertility and mortality, they have tended to continue, with few exceptions. Therefore, most projections for Africa assume the same linear pattern of decline will hold. Yet, the low priority of Africa’s population issues among the world’s wealthiest states, combined with shortfalls in education, development, and contraception, may mean that the demographic transition in Africa will be slower than predicted.
Projections are useful to give us a picture of what the world could look like if meaningful policy changes are made. In the case of sub-Saharan Africa, prospects for these projections are dim.

How Maternal Mortality and Morbidity Impact Economic Development
›
“Investing in women and girls is the right thing to do,” says Mayra Buvinic, sector director of the World Bank’s gender and development group. “It is not only fair for gender equality, but it is smart economics.” But while it may be smart economics, many developing countries fail to address the underlying social causes that impact economic growth, such as poverty and gender inequality. Buvinic was joined by Dr. Nomonde Xundu, health attaché at the Embassy of South Africa in Washington, D.C., and Mary Ellen Stanton, senior maternal health advisor at the U.S. Agency for International Development (USAID), at the sixth meeting of the Advancing Policy Dialogue on Maternal Health Series, which addressed the economic impact of maternal mortality and provided evidence for the need for increased investment in maternal health.

Flooded With Food Insecurity in Pakistan
›The floods sweeping across Pakistan have caused widespread destruction, ruined livelihoods, displaced millions, and sparked a food crisis. Food prices have skyrocketed across the country as miles of farmland succumb to the deluge, including 1.5 million hectares in Punjab province, Pakistan’s breadbasket and agricultural heartland.
Food insecurity is now rife across the country — yet even before the floods, millions of Pakistanis struggled to access food. Back in 2008, the UN estimated that 77 million Pakistanis were hungry and 45 million malnourished. And while many developing nations have begun to recover from the global food crisis of 2007-08, Pakistan’s food fortunes have remained miserable. Throughout 2010, Pakistan’s two chief food staples, rice and wheat, have cost 30 to 50 percent times more than they did before the global food crisis. Drought, rampant water shortages, and conflict have intensified food insecurity in Pakistan in recent months.
A new edited book volume published by the Wilson Center’s Asia Program, Hunger Pains: Pakistan’s Food Insecurity, examines the country’s food insecurity. The book has already been the subject of a news story and an editorial in the Pakistani newspaper Dawn. The book, edited by Michael Kugelman and Robert M. Hathaway, is based on the 2009 Wilson Center conference of the same name. It assesses food supply challenges, access issues, governance constraints, social and structural dimensions, gender and regional disparities, and international responses.
The book makes a range of recommendations. These include:- Declare hunger a national security issue. Since some of Pakistan’s most food-insecure regions lie in militant hotbeds, hunger should be linked to defense, and food provision projects should be given ample public funding.
- Diversify the crop mix so that Pakistan’s agricultural economy revolves around more than wheat and rice. The country should accord more resources to crops that are less water-intensive and more nutritious.
- Give schools a central focus in food aid and food distribution. Using schools as a venue for food distribution gives parents powerful incentives to send their children to school.
- Tackle the structural dimensions. Strengthening agricultural institutions, improving infrastructure and storage facilities, and injecting capital into a stagnant farming sector are all key to making Pakistan more food-secure. Yet unless Pakistan deals with poverty, landlessness, and entrenched political interests in agriculture, food insecurity will remain.

Land, Education, and Fertility in Rural Kenya
›August 10, 2010 // By Wilson Center StaffExcerpted from a summary on the Population Reference Bureau‘s website, by Karina Shreffler and F. Nii-Amoo Dodoo. The original version of this article appeared in Population and Environment 30, no. 3 (2009): 75-92.
Little is known about the role of land inheritance in the link between land availability and fertility. The recent transition from high to lower levels of fertility in some African countries presents an opportunity to clarify the underlying causes of this decline, since the individuals involved in the transitions are still alive.
Using data from focus group discussions with people whose childbearing occurred before and during the rapid and unexpected fertility decline in Nyeri District in rural Kenya, we examined the impact of diminishing land availability, farm size, and inheritance patterns on fertility decisionmaking and behavior. The results shed new light on the role of education, long considered the key determinant of fertility transition.
Our research suggests that rather than inheritance being an external factor affecting fertility behavior, parents in Nyeri District chose to educate their children after realizing they would not be able to bequeath a sufficient amount of land. Our work provides evidence of the importance of considering the influence of environmental factors on demographic processes, particularly in regions of resource dependence.

Population Reference Bureau Releases New Projections
Seven Billion and Counting
›August 6, 2010 // By Russell SticklorThe Population Reference Bureau recently released its annual World Population Data Sheet, and lo and behold, the world is getting more crowded. By next year, the global total is expected to top seven billion, as we march toward upwards of nine billion by mid-century.
Much of that growth, of course, will be unfolding across Asia — China and India already account for more than 35 percent of the world’s population, and the two countries will continue to drive global demographic change. But the PRB report emphasized that Africa will also contribute significantly to world’s shifting demographics in the coming decades. By 2050, the continent’s population is slated to double, reaching the neighborhood of two billion. In that time span, the Democratic Republic of Congo and Ethiopia are expected to knock Russia and Japan off the list of the world’s top 10 most populous nations.
The Young Continent
Africa’s population growth through 2050 could actually be even greater than PRB predicts, since current projections assume that total fertility rate in sub-Saharan Africa will drop from 5.2 to 2.5 in that time span. The assumption is that as the region’s countries travel farther down the path to economic modernization, access to family planning services will become more widespread, resulting in smaller average family sizes—a trend well-documented in other parts of the developing world.
A slower than expected decrease in total fertility rate (TFR) across sub-Saharan Africa over the next 40 years could render current predictions inaccurate, however. While TFR has dropped significantly over the past 50 years in countries like Ghana (where it is now 4.0), just 17 percent of married women in sub-Saharan African utilize a modern type of family planning. That is one of the reasons Africa as a whole maintains a high average TFR of 4.7 children per woman, and why countries like Niger and Uganda sport some of the highest TFRs in the world (at 7.4 and 6.5, respectively).
According to the 2010 PRB Data Sheet, Africa is also notable for its demographic youth bulge. Of the world’s 10 countries with the highest percentage of their populations aged 15 or younger, nine of them—Niger, Uganda, Burkina Faso, the DRC, Zambia, Malawi, Chad, Somalia, and Tanzania—are on the continent. The question facing these countries is whether their young populations will yield a “demographic dividend” during the coming decades, whereby the large youth bulges translate into a sizeable and productive workforce. Harnessing the economic potential of the younger generation could help accelerate the development process in many of the region’s nations, but it will require significant investment in health and education infrastructure—funding that may prove hard to come by for many cash-strapped governments.
Persistent Divides
Other findings featured in the report involved sanitation and wastewater treatment, where some headway is being made at the global level. The PRB Data Sheet reveals that 43 percent of urban populations in sub-Saharan Africa (and 24 percent of the region’s rural populations) now have access to improved sanitation, while 86 percent of urban populations (and 55 percent of rural populations) have better sanitation services in Latin America and the Caribbean. The figures highlight progress, but reveal the significant divide that persists between urban and rural areas in terms of access to quality sanitation. According to the PRB, some 2.7 billion people—40 percent of the world’s total—still do not enjoy adequate sanitation facilities, and most live in rural areas of the developing world.
Finally, an interesting trend that will impact developed and developing nations alike involves elderly support ratios, or the number of active workforce members between the ages of 15 and 64 available to support a nation’s non-working, 65-and-older population. While rapidly growing countries in the developing world will continue to enjoy high elderly support ratios, a number of countries across the developed world will face a potential financial crisis, as comparatively low support ratios combine with rapidly aging populations to strain available financial resources earmarked for covering pension payments and healthcare infrastructure costs. To make up for the shortfall over the coming decades, the PRB report predicts that some developed nations may be inclined to further throw open the doors to immigration to bolster workforce ranks—a step recommended by Jack Goldstone in ECSP Report 13.
