The authors of Asia’s Next Challenge: Securing the Region’s Water Future, a report by the Asia Society, argue that population growth, urbanization, and climate change are converging to make water an important security issue in Asia. The authors argue for including water in policy and development discussions, but warn against “securitizing” the issue.

Contrary to what many people might think, most migration is within the developing world—“among countries that already face enormous challenges in terms of provisions for their populations, but also ethnic conflict,” says Christian Leuprecht in this short video preview of his article, “Migration as the Demographic Wild Card in Civil Conflict: Mauritius and Fiji,” now appearing in the 13th issue of Environmental Change and Security Program Report.

“The ultimate weapon of mass destruction—and perhaps of economic destruction—is the testosterone molecule,” quipped Malcolm Potts at the February 11, 2009, discussion of his new book, “Sex and War: How Biology Explains War and Offers a Path to Peace,” which explores the pivotal question, “Why do human beings systematically and deliberately kill our own species?” Potts, the Bixby Professor of Population and Family Planning at the University of California, Berkeley, was joined Science magazine’s Ann Gibbons, a leading correspondent on human evolution, who examined whether aggressive human behaviors are evolving in response to changing social structures.

Testosterone: Risky Business

“In 1987, some anthropologists and sociologists made a statement at UNESCO that it is scientifically incorrect to say we’ve inherited a tendency to make war from our animal ancestors,” said Potts. “I think that that is wrong.” Evolutionary psychology suggests that humans have inherited certain predispositions that “help us adapt to find food, select mates, avoid danger, and compete for resources in a hostile world,” said Potts. Men compete for women, so it is logical, from a reproductive standpoint, that men would take more risks than women, he argued.

In addition, “there’s strong evidence that there is a genetic tendency for men in the prime of life to attack and kill their neighbors,” Potts noted, while emphasizing that this does not mean that men are preordained to fight one another. “Such predispositions are extraordinarily flexible,” and respond well to peaceful cultural norms.

The Pill Is Mightier Than the Sword

“Once we recognize our violent origins, then we need to ask not ‘why do wars break out?’ but ‘why does peace break out?’” posed Potts. “Judged on the basis of same-species killing,” the violent 20th century may have been the most peaceful in human history, he claimed.

“In the whole of recorded history, I cannot find a single example of women banding together spontaneously and then going out to attack a neighboring group,” maintained Potts. He argued that increasing women’s individual freedom and collective power in civil society and government is the best way to achieve a more peaceful world. More specifically, slowing population growth and promoting more balanced age structures by giving women access to family planning will contribute not just to their own autonomy, but also to long-term peace, he argued.

Evolving To Become Less Aggressive?

“Humans are capable of incredible acts of kindness but also despicable acts of terror,” said Gibbons. “We murder, slaughter, barbeque, and even eat our own species, and we’ve been doing it for a long time.” But it is difficult to determine whether this propensity for aggression is an ancient trait or has more recently evolved. “There are no other human species alive to show us different models for male aggression…so we have look at fossils, DNA, and our closest relatives—the chimpanzees and gorillas,” Gibbons said.

Human aggression may be continuing to evolve. As Gibbons explained, “researchers, as they look at the human genome project—the HapMap Project—have discovered there are many, many genes that have come under natural selection that have evolved in the last 100,000 years, since modern humans spread out of Africa.” Therefore, as warfare becomes less necessary to our daily survival, our species might evolve to become less aggressive. “Are we seeing, in our sexual selection, mates being chosen that are a little less aggressive?” Gibbons asked. “We are still evolving,” she emphasized. “The story isn’t over yet.”

“Demography will have a greater role in defense planning in the future,” says Jennifer Dabbs Sciubba in this short video preview of her article, “Population in Defense Policy Planning,” now appearing in the 13th issue of Environmental Change and Security Program Report. “Robert Gates has put a lot of emphasis on development as a key to peace, and Africa Command may be the area that brings together issues of demography, the environment, and development, and sends those observations back up the higher levels at DOD,” she observes. Sciubba, Mellon Environmental Fellow in the Department of International Studies at Rhodes College, and six other demographic experts analyze the links connecting population and environmental dynamics to conflict in a set of commentaries on “New Directions in Demographic Security.”

From Conflict to Peacebuilding: The Role of Natural Resources and the Environment, based on the work of the UN Environment Programme’s Expert Advisory Group on Environment, Conflict and Peacebuilding, summarizes the links between the environment, conflict, and peacebuilding, and includes 14 case studies of how natural resources affect—or are affected by—conflict.

The authors of “On Population Growth Near Protected Areas” come to an opposite conclusion from Wittemyer et al., who found a pattern of higher population growth near protected areas in Africa and Latin America. “To understand the disagreement, we re-analyzed the protected areas in Wittemyer et al.’s paper. Their results are simply artifacts of mixing two incompatible datasets,” write the authors. “Protected areas may experience unusual population pressures near their edges; indeed, individual case studies provide examples. There is no evidence, however, of a general pattern of disproportionate population growth near protected areas.”

“The President and I agreed to a new initiative that will further cross-border cooperation on environmental protection and environmental security,” said Canadian Prime Minister Stephen Harper yesterday, announcing plans for a U.S.-Canada Clean Energy Dialogue.

Scientists at Purdue University have teamed up with Google Earth to create an interactive map of U.S. CO2 emissions.

Mark Weston, who writes for the Global Dashboard blog, posted an edited version of a recent talk he gave on West African demography and security.

In the annual threat assessment he presented last week to the Senate Select Committee on Intelligence, new Director of National Intelligence Dennis Blair named the global economic crisis—not terrorism—the primary near-term threat to U.S. national security, prompting accusations of partisanship from the Washington Times. Yet as the U.S. Naval War College’s Derek Reveron notes, “the economic turmoil of the early 20th century fueled global instability and war,” and today’s economic collapse could strengthen extremists and deprive U.S. allies of the funds they need to deploy troops or increase foreign assistance to vulnerable regions.

Further down the list of potential catastrophes—after terrorism, cybersecurity, and the “arc of instability” that stretches from the Middle East to South Asia—the assessment tackles environmental security threats. The four-page section, which likely draws on sections of the recent National Intelligence Council report Global Trends 2025: A Transformed World, summarizes the interrelated natural-resource and population challenges—including energy, food, water, demography, climate change, and global health—the U.S. intelligence community is tracking.

The world will face mounting resource scarcity, warns Blair. “Access to relatively secure and clean energy sources and management of chronic food and water shortages will assume increasing importance for a growing number of countries. Adding well over a billion people to the world’s population by 2025 will itself put pressure on these vital resources,” he writes.

Drawing on the conclusions of the 2008 National Intelligence Assessment on the impacts of global climate change to 2030, Blair portrays climate change as a variable that could place additional strain on already-stressed agricultural, energy, and water systems: “We assess climate change alone is unlikely to trigger state failure in any state out to 2030, but the impacts will worsen existing problems such as poverty, social tensions, environmental degradation, ineffectual leadership, and weak political institutions.” Direct impacts to the United States include “warming temperatures, changes in precipitation patterns, and possible increases in the severity of storms in the Gulf, increased demand for energy resources, disruptions in US and Arctic infrastructure, and increases in immigration from resource-scarce regions of the world,” writes Blair.

Africa, as usual, is the last of the world’s regions to be analyzed in the assessment. Blair notes that “a shortage of skilled medical personnel, deteriorating health systems, and inadequate budgets to deal with diseases like HIV/AIDS, malaria, and tuberculosis” is threatening stability in sub-Saharan Africa, and explains that agriculture, which he rightly calls “the foundation of most African economies,” is not yet self-sufficient, although some countries have made significant improvements in infrastructure and technology. He highlights ongoing conflicts in the Democratic Republic of the Congo, Nigeria, Sudan, and Somalia as the most serious security challenges in Africa. He fails to note, however, that all four have environmental/natural resource dimensions (see above links for details).

“The whole world is aging, and the developed countries are leading the way,” said Neil Howe of the Center for Strategic and International Studies (CSIS) at a January 27, 2009, Wilson Center discussion of his latest report, The Graying of the Great Powers: Demography and Geopolitics in the 21st Century. Demography is as close as social science comes to predicting the future, Howe explained, presenting the geopolitical consequences of demographic trends over the next 50 years. Howe and co-author Richard Jackson, also of CSIS, were joined by Jennifer Sciubba of Rhodes College, who urged them and other demographers to explore how population trends interact with additional variables, such as environmental degradation, economic recession, and conflict.

Danger: Demographic Decline Approaching

“Populations in most developed countries will not only age, but stagnate or decline,” due to falling fertility and rising longevity, said Howe. Without “sizable immigration,” he warned, the populations of countries like the United States, France, Great Britain, Canada, Germany, and Japan will decline. As developed countries’ populations shrink, they will lose military might, savings and investment, entrepreneurship, and cultural influence. “Voltaire once said that God is on the side of biggest battalions,” Howe reminded the audience.

Developing Toward Greater Peace

Jackson explained that the developing world is in the midst of the “demographic transition”—the drops in mortality and fertility that generally accompany economic and social development. Since 1970, the developing world’s overall fertility rate has declined from 5.1 to 2.9 children per woman, and its overall population growth rate has dropped from 2.2 percent to 1.3 percent per year, according to Jackson. Additionally, the median age has risen from 20 to 26 years old, “a cause for hope and optimism about the future,” Jackson argued, as countries with more balanced population age structures tend to be more democratic, prosperous, and peaceful than countries with extremely young ones.

But despite the long-term possibility of a world transitioning toward greater peace and prosperity, the developing world will still experience near-term shocks. The timing and pace of the demographic transition varies widely by country and region, with some countries transitioning too fast or too far, said Jackson. These trends could push developing countries toward social collapse by acting “as a kind of multiplier on all the stresses of development,” explained Jackson—for instance, causing China “to lurch even more toward neo-authoritarianism.”

Crisis of the 2020s

Global demographic trends will converge in the 2020s to make that decade “very challenging,” said Howe. The developed world will undergo hyper-aging, population decline, and flattening GDP growth, along with rising pension and health care costs, Jackson noted. The Muslim world will experience a decade of temporary youth bulges, as the large generation that was born between 1990 and 2000 has children. The populations of Russia and Eastern Europe will implode, and Russia’s geopolitical strength and influence will wane. Meanwhile, China will experience a decade of “premature aging”; due to its one-child policy, it will become “gray” before it achieves the per capita GDP of most aging countries.

Demography and Public Policy

Sciubba praised the report’s comprehensive, policy-friendly approach to demography, but urged the authors to remain true to the nuances of their topic, even in their conclusions and recommendations. “Policymakers like to know what we don’t know and what we do know. And with population aging and national security, often there’s a lot more of what we don’t know than what we do know,” she said. “Going into the future, we need more of an emphasis on places where policymakers can make a difference,” said Sciubba. “Opportunities matter just as much as challenges.”

“Demographics are going to be to the 21st century what class cleavages were to the 19th century,” says Christian Leuprecht in this short expert analysis from the Environmental Change and Security Program. In this video, Leuprecht, an assistant professor at the Royal Military College of Canada, makes the case for the importance of demographic dynamics and their connections to conflict and security.
