The “demographic dividend,” a concept that marries population dynamics and development economics, is on the rise in policy circles – Rajiv Shah, Melinda Gates, and African government ministers have all discussed it recently in high-level forums. Most notably for demographers, World Bank Chief Economist Justin Yifu Lin wrote a blog post that focuses on the demographic dividend’s potential to give developing countries a powerful economic boost through declining dependency ratios and a proportionately large working-age population.

“There are 750 million adolescent girls in the world today, and this is by far one of the world’s most marginalized and vulnerable demographics,” said Denise Dunning, the Public Health Institute’s program director for emergency contraception in Latin America during a February 2 panel at the Wilson Center. Dunning, who also leads the Adolescent Girls’ Advocacy and Leadership Initiative (AGALI), was joined by Margaret Greene, director of Greeneworks, and Jennifer Pope, the deputy director of sexual and reproductive health at Population Services International, to discuss how to better reach underserved adolescent girls in developing countries with health and livelihood programs.

“Across the Sahel region of western Africa, a combination of drought, poverty, high grain prices, environmental degradation, and chronic underdevelopment is expected to plunge millions of people into a new food and nutrition crisis this year,” according to a UN Office for the Coordination of Humanitarian Affairs (OCHA) statement from February 10. The coming “lean season” is predicted to be the third food crisis in less than a decade and highlights a set of glaring vulnerabilities in a region facing severe long-term threats to health, livelihoods, and security. However, as international agencies call for funding to mount yet another emergency response, serious concerns are being raised about what is (or isn’t) being done to address the root causes of vulnerability.

The Defense Science Board, which advices the U.S. military on scientific and technical matters, writes in a recent task force report that the most immediate and destabilizing effects of climate change will impact U.S. security indirectly, through American reliance on already-vulnerable states that are “vital” sources of fuel and minerals or key partners in combatting terrorism. The report singles out three specific themes as particularly important to responding to near-term climate-driven threats and adapting to climate change’s long-term impacts: providing “better and more credible information [about climate change] to decision makers,” improving water management, and building better local adaptation capacity, particularly in African nations. Ultimately, the report concludes that the most effective, most efficient way the United States can respond to climate change is not militarily but “through anticipatory and preventative actions using primarily indigenous resources.”

“There’s been a tremendous amount of work done on looking for a climate signal for civil conflict, particularly in sub-Saharan Africa, and a lot of this work draws a very clear and simple path – if it rains more, or if it rains less, there will be more or less conflict,” says Stanford University’s Kaitlin Shilling in this short video interview. Unfortunately, that straightforward research does little in the way of helping policymakers: “the only way to change the agricultural outputs due to climate change is to change climate change, reduce climate change, or stop it,” she says, “and we’re not really good at that part.”

Several years ago, I wrote that the central irony concerning Africa’s urban youth was that “they are a demographic majority that sees itself as an outcast minority.” Since that time, field research with rural and urban youth in war and postwar contexts within and beyond Africa has led me to revise this assertion. The irony appears to apply to most developing country youth regardless of their location.

Since the concept of “environmental security” first gained traction in the early 1990s, research on the issue has been overwhelmingly focused on how environmental change impacts state security. That has been to the detriment of policymakers trying to preempt instability and conflict, according to the University of Toronto’s Tom Deligiannis in his article, “The Evolution of Environment-Conflict Research: Toward a Livelihood Framework,” published in February’s Global Environmental Politics.

Late last year, Afghanistan’s first-ever nationally representative survey of demographic and health issues was published, providing estimates of indicators that had previously been modeled or inferred from smaller samples. It shows that Afghan women have an average of five children each, lower than most experts had anticipated, and that their rate of modern contraceptive use is just slightly lower than that of women in neighboring Pakistan.
