Adding it Up: The Costs and Benefits of Investing in Family Planning and Maternal and Newborn Health, a report by the Guttmacher Institute, asserts that “sustained and increased investment in sexual and reproductive health services in developing countries” would “contribute to economic growth, societal and gender equity, and democratic governance.” The report presents cost-benefit analyses of family planning and maternal and newborn health strategies in an effort to “guide decision makers, at the global, regional and country levels, in making investments that would reap the greatest returns for individuals and societies.”

The journal Nature Geoscience recently published a study comparing the impacts of rural and urban population growth on deforestation. “Deforestation Driven by Urban Population Growth and Agricultural Trade in the Twenty-First Century” finds deforestation is positively correlated with urban population growth and agricultural exports to international markets. In rural areas, however, the link between deforestation and population growth was absent, indicating that urbanization and agricultural export-oriented economies were the primary drivers for forest loss. The study concludes that, rather than focusing on the activities of rural populations, deforestation reduction efforts should target “industrial-scale, export-oriented agricultural production, concomitant with efforts to increase yields in non-forested lands.” (SUBSCRIPTION ONLY)

Climate Change and Security in Africa: A Study for the Nordic-African Foreign Ministers Meeting, a collaboration between the International Institute for Sustainable Development and the Institute for Security Studies, examines the spectrum of literature devoted to the security implications of climate change in Africa. In particular, the study focuses on the economic sectors and regions most susceptible to climate change’s threat multiplier effects. It concludes that “climate change presents very real development challenges which, under certain circumstances, may contribute to the emergence and longevity of conflict.”

Right now, Rich Cincotta is live on “PRB Discuss Online,” answering the question, “Does a Young Age Structure Thwart Democratic Governments?” He is responding to reader questions like “Do Democratic governments being overcome by poverty and high unemployment rates have a chance to succeed” and “Why do you think the mainstream demography community is so slow or unwilling to pick up the research questions you have pursued?” Read the transcript and Cincotta’s recent article on this topic, “Half a Chance: Youth Bulges and Transitions to Liberal Democracy.”

A new World Bank working paper, “Breaking the Waves? Does Education Mediate the Relationship Between Youth Bulges and Political Violence?” by Bilal Barakat and Henrik Urdal finds “evidence that large, young male population bulges are more likely to increase the risk of conflict in societies where male secondary education is low”–particularly in low and middle-income countries. Mardy Shualy of Foreign Policy’s blog suggests policymakers do the math to compare the costs of secondary education to the economic toll of war and civil conflict.

Climate change is “the biggest global health threat of the 21st century,” says the final report of a year-long commission held by The Lancet and University College London. A Lancet editorial, “Sexual and reproductive health and climate change,” says that rapid population growth “increases the scale of vulnerability to the consequences of climate change” and that meeting the unmet need for contraception “could slow high rates of population growth, thereby reducing demographic pressure on the environment.”

The American Security Project (ASP) launched its Climate Security Index, which identifies climate change “a clear and present danger to the national security of the United States,” at an event hosted by George Washington University. ASP warns that “American leaders will face a multitude of tough choices as climate-induced national security threats begin to compete with and crowd out our ability to respond to traditional threats,” reports ClimateWire.

In an Economist.com debate on population growth between John Seager of Population Connection and Michael Lind of the New America Foundation, Seager argues that rapid population growth is “the source of many of the world’s—especially the poor world’s—woes,” as it accelerates environmental degradation and “undermines both security and development.” On the other hand, Lind counters that “countries are not poor because they have too many people,” and asserts that “technology and increased efficiency have refuted what looks like imminent resource exhaustion.”

Christian Aid’s “Growing Pains: The Possibilities and Problems of Biofuels” finds that “huge subsidies and targets in developed countries for boosting the production of fuels from plants such as maize and palm oil are exacerbating environmental and social problems in poor nations.”
