December and January were busy months. The U.S. National Intelligence Council released their latest quadrennial Global Trends Report, we saw a progress report on USAID’s Feed the Future Initiative, and Typhoon Bopha showed why developing countries are so vulnerable to climate change. Laurie Mazur also responded to Blair A. Ruble’s Wilson Center policy brief on 21st century urbanization with a look at how sustainable cities really are, and we heard from Ethiopia’s PHE community about the challenges of project monitoring and evaluation. Some past-year favorites emerged again as well, with Yemen’s demography, a look at Mongolia’s mining boom, and a great map of the world’s exclusive economic zones.

If 2011 was the year of political demography, then 2012 was perhaps when the full intersection of natural resource management, population dynamics, development, and security came into focus. The U.S. drought; global food price spikes; the return of famine in the Sahel and Horn of Africa; continued unrest in youthful countries across the Middle East; the Rio+20 and London Family Planning summits; new oil and mineral development in unstable countries; and increasingly more noticeable climate change around the world – all were big stories that brought the intersection of these issues to the forefront.

Population and environment stories nearly swept the top 10 last month (ranked by unique pageviews). Sean Peoples’ first short film on population, health, and environment projects in Tanzania led the charge, followed by a guest post from Tim Tear and Craig Leisher of The Nature Conservancy; Ken Weiss’ Beyond Seven Billion event; Elizabeth Leahy Madsen’s look at Yemen’s demography; Kathleen Mogelgaard’s post on next steps for incorporating population dynamics in climate change; and a summary of Joel Cohen’s 45-minute YouTube introduction to demography for the Floating University.

Water – and its relationship with development, food, demography, and conflict – dominated October’s top 10 posts. Jeremiah Asaka’s guest contribution on resource conflict in Kenya and Kate Diamond’s look at SAB Miller’s surprisingly on-point summary of the water-energy-food nexus were new additions. Carolyn Lamere’s posts on the health of the world’s major aquifers and the political situation along the Nile basin made reappearances. And the drought across the U.S. West is still on, driving interest in Graham Norwood’s summary of how it might impact world food prices and its connection to climate change.

September brought a crop of fresh faces to the top 10 (based on unique pageviews). Valerie Hudson’s spring launch at the Wilson Center of her new book Sex and World Peace, which asks if the domestic treatment of women impacts the security of states, was very popular, and Carolyn Lamere’s snapshot of the current political and development situation along the Nile river basin also jumped the charts.

August is a slow month in DC, but not so on New Security Beat: 8 of the top 10 last month (measured by unique pageviews) were new posts. Laurie Mazur’s discussion of inequality, population, and sustainability took the top spot followed by a look at what’s new in the Population Reference Bureau’s latest data sheet; Kate Diamond’s feature on Mongolia’s climate and development challenges; a discussion on the naming of the Failed States Index; a summary of the National Intelligence Council’s extensive series on aging; and two reactions to Iran’s surprising shift on family planning.

Kate Diamond’s look at Mongolia’s nexus of climate, development, and extractive industry issues ran away with the top spot last month (measured by unique pageviews) and was joined by a host of newcomers. We updated you on Afghanistan’s mineral potential and continuing maternal health issues; reviewed CAP’s climate-migration report, CCAPS’s climate-conflict mapping tool, and David Bonnardeaux’s treatise on integrated development in Africa; and examined some of USAID’s recent open data initiatives and what they might signal for the agency moving forward.

With the focus on sustainable development last month, Rio+20 coverage and related-population, health, and environment stories crept into the top posts (measured by unique pageviews). Carl Haub of Population Reference Bureau made a surprise appearance too with his update on the Democratic Republic of Congo’s latest demographic and health survey coming in at number three.
