“Does Family Planning Bring Down Fertility” in Science’s special July issue on population, author Jocelyn Kaiser engages various experts to explore whether family planning programs actually help to reduce high fertility. Social demographer Amy Tsui of Johns Hopkins University argues that surveys indicating “unmet need” in family planning “don’t tell us anything about causation.” On the other hand, Martha Campbell, a lecturer at the University of California, stressed that in countries such as Niger where the population could soar from 16 million today to 58 million by 2050, “You can’t expand [schools] fast enough.” Thus, focusing on family planning is indispensable and “the benefits [will] far outweigh the costs.”

In “A New Hope for Africa,” published in last month’s issue of Nature, authors Lee R. Lynd and Jeremy Woods assert that the international development community should “cut with the beneficial edge of bioenergy’s double-edged sword” to enhance food security in Africa. According to Lynd and Woods, Africa’s severe food insecurity is a “legacy of three decades of neglect for agricultural development.” Left out of the Green Revolution in the 1960s, the region was flooded with cheap food imports from developed nations while local agricultural sectors remained underdeveloped. With thoughtful management, bioenergy production on marginal lands unfit for edible crops may yield several food security benefits, such as increased employment, improved agricultural infrastructure, energy democratization, land regeneration, and reduced conflict, write the authors.

Energy for the War Fighter is the U.S. Department of Defense’s first operational energy strategy, mandated by congress last year. Energy security for the department means having assured access to reliable supplies of energy and the ability to protect and deliver energy to meet operational (non-facilities-related) needs. The report is divided into three main parts, which address reducing current demand for energy in military operations; expanding and securing the supply of energy for military operations; and building consideration of energy security into future force decisions. The strategy is designed to both support current military operations and to focus future energy investments accordingly. Previous federal energy mandates exempted the military’s field operations, which account for three-quarters of the department’s energy consumption. The department as a whole makes up 80 percent of the federal government’s annual energy use.

The Water Energy Nexus: Adding Water to the Energy Agenda, by Diana Glassman, Michele Wucker, Tanushree Isaacman, and Corinne Champilouis of the World Policy Institute, attempts to show the correlation between energy and water to motivate policy makers to consider the implications of their dual consumption. “Nations around the world are evaluating their energy options and developing policies that apply appropriate financial carrots and sticks to various technologies to encourage sustainable energy production, including cost, carbon, and security considerations,” write the authors. “Water needs to be a part of this debate, particularly how communities will manage the trade-offs between water and energy at the local, national, and cross-border levels.” The study provides the context needed to evaluate key tradeoffs between water and energy by providing “the most credible available data about water consumption per unit of energy produced across a wide spectrum of traditional energy technologies,” they write.

“Practice, Harvest and Exchange: Exploring and Mapping the Global, Health, Environment (PHE) Network of Practice,” by the University of Rhode Island’s Coastal Resources Institute and the USAID-supported BALANCED Project, explores the successes and challenges of their global population, health, and environment (PHE) network (with a heavy presence in East Africa). In order to increase support of the nascent PHE approach, the network seeks to shorten the “collaborative distance” between “PHE champions,” so they can develop a stronger body of evidence for the links between population, health, and the environment. In their analysis, the authors write that the network has facilitated the development of independent, information-sharing relationships between “champions.” However, they also observed shortfalls in the network, such as its limited reach into less technologically advanced yet more biodiverse regions, its bias toward BALANCED meet-up event participants, and its exclusion of those experts unlikely to be included in published works.

In the chapter, “Urban Agriculture and Climate Change Adaptation: Ensuring Food Security Through Adaptation,” of the edited volume, Resilient Cities: Cities and Adaptation to Climate Change – Proceedings of the Global Forum 2010, authors Marielle Debbeling and Henk de Zeeuw assess the viability of urban and peri-urban agriculture (UPA) as a method of climate change adaptation for the urban poor. Debbeling and de Zeeuw assert that UPA increases the resilience of cities by diversifying both food supply and income streams for the urban poor; decreasing the negative effects of “heat island effect,” air pollution, and urban flooding; conserving water and utilizing organic waste; and reducing energy use and greenhouse gas emissions. Given the scale and impact of modern urbanization, the authors write that “the integration of UPA into urban development and master plans, urban land use and zoning plans, as well as active maintenance of the protected agricultural zones…is crucial.”

In a study from the Center for Sustainable Development at Uppsala University in Sweden titled “Climate Change and the Risk of Violent Conflicts in Southern Africa,” authors Ashok Swain, Ranjula Bali Swain, Anders Themnér, and Florian Krampe examine the potential for climate change and variability to act as a “threat multiplier” in the Zambezi River Basin. The report argues that “socio-economic and political problems are disproportionately multiplied by climate change/variability.” A reliance on agriculture, poor governance, weak institutions, polarized social identities, and economic challenges in the region are issues that may combine with climate change to increase the potential for conflict. Specifically, the report concludes that the Matableleland-North Province in Zimbabwe and Zambezia Province in Mozambique are the areas in the region most likely to experience climate-induced conflicts in the near future.

In The Lancet’s “How Did Sierra Leone Provide Free Health Care?,” author John Donnelly of the Ministerial Leadership Initiative attributes the unanticipated success of a free health care program for women and children in Sierra Leone to good organization, transparency, and a high degree of cooperation between the government, donors, and development partners. One distinctive factor that has contributed to the health system’s turnaround is the unusually high level of political will on the part of President Ernest Bai Koroma, writes Donnelly. Similar to Egypt’s health and population initiatives, Sierra Leone’s marked commitment, accountability, and investment as a host country has contributed highly to the success of its program and triggered further investment from donors.

In a report titled “Elements of Security: Mitigating the Risks of U.S. Dependence on Critical Minerals,” author Christine Parthemore from the Center for a New American Security writes, “Growing global demand coupled with the mineral requirements necessary for both managing military supply chains and transitioning to a clean energy future will require not only clearer understanding, but also pragmatic and realistic solutions.” Minerals and rare earth elements such as lithium, gallium, and rhenium are critical elements for many defense technologies (e.g. jet engines, satellites, missiles, etc.) and alternative energy sources (batteries and wind turbines). Parthemore argues that U.S. policy should focus on preventing suppliers from exerting undue leverage (as China did in 2010), mitigating fiscal risk and cost overruns, reducing disruption vulnerability, and ensuring the United States is able to meet its growth goals in clean energy and other high-tech fields.
