“In a future world affected by climate change, population growth is one lever that can be addressed to ameliorate the impacts of climate change, particularly in the area of food security,” write Scott Moreland and Ellen Smith in “Modeling Climate Change, Food Security, and Population,” a recent study for MEASURE Evaluation and USAID. Moreland and Smith combine demographic changes, food needs, and economic capacity into a single aggregate model to assess how family planning and climate change might affect food security from now until 2050. Using Ethiopia as an example, the model finds that if access to family planning services were increased to meet existing needs, the subsequent decrease in demand for food would reduce child malnutrition and effectively counteract a projected 25 percent shortfall in caloric availability from climate change’s impact on agriculture. Programs designed to increase access to family planning should therefore be incorporated into national adaptation and food security strategies, they conclude. “Family planning, especially in countries with high unmet need, provides a potential solution not only for women’s reproductive health, but also for adapting to the effects of climate change.”

“Water security is about much more than access to H2O,” said Jane Harman, director, president, and CEO of the Wilson Center at the May 9 meeting, “Global Water Security: The Intelligence Community Assessment.” The event – part of the Wilson Center’s National Conversation Series – brought together a number of experts to discuss a recently released intelligence community assessment of global water security.

A few months ago, Elizabeth Leahy Madsen broke down Afghanistan’s first-ever nationally representative survey of demographic and health issues in a two-part series here on the blog. Now, we’ve published her analysis in a rich new policy brief format. It is the first issue of Environmental Change and Security Program Report 14, the latest volume of ECSP’s flagship publication.

Population issues have been conspicuously absent from the discussions on the environmental sustainability of our globalized economy in the run-up to the Rio+20 Conference on Sustainable Development, which will take place in Brazil, June 20-22, under the auspices of the United Nations.

In the coming years, Nigeria’s cohort of unemployed youth has equal potential to “be converted into either a religious or a regional clash, as certain youths get opportunities and other youths do not,” said Pauline Baker, President Emeritus of the Fund for Peace, during the day-long “Nigeria Behind the Headlines” event at the Wilson Center on the April 25 (read part one here).

“Nigeria is a country of marginalized people. Every group you talk to, from the Ijaws to the Hausas, will tell you they are marginalized,” said Peter Lewis, director of the African Studies Program at the Johns Hopkins University School of Advanced International Studies. Lewis spoke at an April 25 conference on Nigeria, co-hosted by ECSP and the Wilson Center’s Africa Program, assessing the country’s opportunities for development given its demographic, governance, natural resource, health, and security challenges.

In late May, I presented research on population and climate dynamics in hotspots at the Planet Under Pressure conference in London, in a session organized by the Climate and Development Knowledge Network. As we prepare for the Rio+20 Earth Summit in June, I reflect on the roles of population dynamics and climate-compatible development for ensuring a future where we can increase the resilience of the most vulnerable to the impacts of climate change.

The pace of fertility decline in sub-Saharan Africa will be the single most important factor in whether the global population reaches the UN’s high projection of nearly 11 billion in 2050, or remains closer to the low projection of 8 billion. In recent years, the high projection has seemed more likely, as sub-Saharan Africa has been marked by stalled fertility declines and stagnant rates of contraceptive use. Survey results released over the past year showing dramatic increases in contraceptive use in Ethiopia, Malawi, and Rwanda therefore set demographers and the family planning community abuzz, signaling that concerted efforts to improve health services had paid off and fertility rates were on the decline. But in recent months, additional surveys from Mozambique, Uganda, and Zimbabwe have shown that those positive trends are not universal.
