Stretching across northern Africa, the Sahel is a semi-arid region of more than a million square miles covering parts of nine countries. It is home to one of the world’s most punishing climates; vast expanses of uncharted and unmonitored desert; busy migration corridors that host human, drug, and arms trafficking; governments that are often ineffective and corrupt; and crushing poverty. It is not surprising then that the area has experienced a long history of unrest, marked by frequent military clashes, overthrown governments, and insurgency.

One year ago, the United States government froze all property of the Central Bank of Iran and other Iranian financial institutions within the United States. The move was part of a broader effort to compel the Islamic Republic to give up its alleged nuclear weapons program. How is it working out?

Once highly dependent on revenue from petroleum sales, the Syrian government has lost control of many of the country’s major oil fields over the past few months as Kurdish forces and the rebel Free Syrian Army have made significant gains in the east.

It’s spring, it’s Earth Day, and I’m starting a new job. I always enjoy the sense of renewal that spring brings, and this spring brings a unique opportunity for me to reaffirm my commitment to the issues that define our times. As the Wilson Center’s new Director of Population, Environmental Change, and Security, I am excited to build on the success of the Center’s Environmental Change and Security Program and Global Health Initiative to forge new paths and identify ways that reproductive health, environmental conservation, and women’s empowerment affect our lives today and in the future.

Environmental security and international development aren’t typical movie-going fare, but at the 2013 DC Environmental Film Festival, ECSP premiered two short documentaries with unique environmental stories: Healthy People, Healthy Environment: Integrated Development in Tanzania shows how improving health services and environmental conservation can empower coastal communities in Africa; and Transcending Boundaries: Perspectives from the Central Albertine Rift Transfrontier Protected Area Network explores the opportunities for “peace parks” along the shared borders of Uganda, Rwanda, and the Democratic Republic of Congo.

“There is a huge gap between climate science, policymakers, and the end-users, in terms of understanding climate change and adaptation, and how that relates to conflict or peace,” concluded 26 experts from more than 10 countries across sub-Saharan Africa at the Wilson Center last fall. But “climate change adaptation is crucial to achieving Africa’s aspirations for peace, security, and sustainable development.”

From the 2004 Indian Ocean tsunami to Superstorm Sandy, the last decade has seen an incredible array of natural disasters. Of course, disasters of all kinds are nothing new, but, thanks to the growing scale and interconnectedness of the human enterprise – and the damage we have done to the natural world – the frequency, scale, and consequences of today’s calamities are truly without precedent.

In “On Demographic and Democratic Transitions,” published in the February edition of Population and Development Review, author Tim Dyson postulates that the so-called “demographic transition” – a two-step process in which diminishing mortality rates are followed by decreases in total fertility – is an important predictor of a society’s transition from autocracy to democracy. Specifically, Dyson suggests that the population surge resulting from a decline in mortality may tend to destabilize pre-democratic regimes, while a subsequent drop in fertility rates may empower women and raise the median age of a population, thus paving the way for democracy to emerge. Dyson demonstrates a statistically significant correlation between population aging and inclination toward democracy, echoing the work of New Security Beat contributor, Richard Cincotta.
