This summer, 26 countries and private donors met at the London Summit on Family Planning to pledge $2.6 billion to expand family planning services to 120 million more women in the poorest countries around the world. But while the summit renewed focus on reproductive health with its ambitious target, “we’re now at that point where we have to really sit down and work through” how to achieve that goal, said Julia Bunting of the UK’s Department for International Development at the Wilson Center on September 17.

People are still talking about this summer’s London Summit on Family Planning, which was hosted by the Bill and Melinda Gates Foundation and the UK’s Department of International Development (DIFD) on July 11. On Monday here at the Wilson Center, the Environmental Change and Security Program featured representatives from USAID, DFID, and Gates Foundation for a standing-room only panel discussion of the landmark event.

There are 1.2 billion adolescents (ages 10 to 19) in the world today, accounting for 17 percent of the global population. They are the largest youth cohort in history, and 90 percent live in the developing world. Within that broad age group, very young adolescents (ages 10 to 14) often fall through the cracks of international development work, especially when it comes to health, and reproductive health in particular.

Contraceptives prevented an estimated 272,040 maternal deaths in 2008, reducing worldwide maternal mortality by 44 percent, according to a recent paper by Saifuddin Ahmed, Qingfeng Li, Li Liu, and Amy O. Tsui, published in The Lancet. But the prevention of maternal deaths could have been even higher. The study, “Maternal Deaths Averted by Contraceptive Use: An Analysis of 172 Countries,” estimates that an additional 104,000 maternal deaths – many occurring in developing parts of Africa and South Asia – could have been averted simply by satisfying existing unmet need for contraception. In sub-Saharan Africa, for example, only 22 percent of women who are married or sexually active use contraception – a far cry from the 65 percent which the study suggests is the point at which maternal deaths avoided by contraceptive use begin to plateau. Not surprisingly, this has also yielded some of the highest regional fertility rates in the world.

Such high fertility rates are driving growing concerns about scarcity and capacity in the region, and how climate change might exacerbate already-difficult development hurdles. This nexus of issues was the subject of a recent policy brief by Population Action International and the African Institute for Development Policy, titled Population, Climate Change, and Sustainable Development in Africa. The brief points out that “a large share of Africa’s population lives in areas susceptible to climate variation and extreme weather events,” and that there is an inherent tension the continent faces as it seeks to balance high population growth with climate change-induced reductions in the availability of natural resources, like water and arable land.  The authors urge policymakers, rather than focusing on environment, population, and health individually, to “connect population dynamics and climate change” to address their interlinked challenges together.

“It is plausible that key transitions in human evolutionary history have been driven in large part by climate change,” write Eugene A. Rosa and Thomas Dietz in “Human Drivers of National Greenhouse-Gas Emissions,” a literature review published by Nature Climate Change. “Changes in climate will doubtless be a key force in the future evolution of social systems, including all aspects of social, economic, and political life, while impinging on the health and well-being of the individuals who populate them.” Rosa and Dietz cite numerous studies to argue that nearly every facet of society will be affected by climate change. “The critical point,” they write, “is that population, affluence, technology, and all other drivers act not alone or additively but in a multiplicative fashion.” For example, rapid population growth can lead to an increase in urbanization, which generates “substantial demand for goods and services that can induce emissions in distant places.” They conclude that huge changes must be made in technology and consumption in order to combat the effects of climate change that are being caused by a growing population and an increasingly affluent world.

Afghanistan has one of the highest rates of maternal mortality in the world: 327 out of every 100,000 women who give birth die during childbirth. Despite some recent improvements, political, social, cultural, and economic factors present enormous challenges. Last month, the Center for Population and Development Activities hosted an online viewing and dialogue discussion of the PBS Independent Lens film Motherland Afghanistan, which follows Afghan-American filmmaker Sedika Mojadidi and her father, Dr. Qudrat Mojadid, as they return to their home country and visit the Laura Bush Maternity Ward in Kabul. The conditions they find are devastating and underscore not only the need for greater commitment to reproductive health services, but also the advancement of women’s and girl’s access to education, security, and political participation.

“Given the option, [women in developing countries] will have fewer children,” said Melinda Gates in a TEDxChange talk in April. “The question is: are we going to commit to helping them get what they want now? Or are we going to condemn them to some century-long struggle, as if this were still revolutionary France and the best method was still coitus interruptus?”

The Guttmacher Institute has updated their estimates for global contraceptive services, putting the number of women around the world who have an unmet need for modern family planning at 222 million (up from 215 million). Authors Susheela Singh and Jacqueline E. Darroch, in Adding It Up: Costs and Benefits of Contraceptive Services Estimates for 2012, also examine the estimated current costs of contraception, cost of meeting the current unmet need, and the money saved from having fewer unintended pregnancies. An estimated four billion dollars is currently spent on contraception in the developing world, and “the total cost of fully meeting the contraceptive needs of all women in the developing world with appropriate services would…be $8.1 billion per year.” Singh and Darroch note that there are substantial benefits to increasing access to contraception, including reduced infant and maternal mortality and lower education and health costs as smaller populations put less strain on existing systems. They conclude that “the gains that derive from meeting the contraceptive needs of all women in the developing world more than outweigh the financial costs.”
