“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.

Not long ago, concerns about environmental degradation were marginal in U.S. national security deliberations. What a difference climate change has made. Foreign policy officials and experts are starting to recognize profound linkages between planetary health, economic prosperity, and international security. These connections were on full view last Wednesday, when the Council on Foreign Relations (CFR) teamed up with Conservation International (CI) to convene a symposium, “Global Resources, the U.S. Economy, and National Security.”

After spending almost two weeks in India’s northwestern state of Haryana, the destination for many trafficked brides, we decided to head to the source area. It lies two hours by plane to the east, in the lush green hills of Assam. Here, as well as in the surrounding states of West Bengal, Bihar, and Nagaland, many women are trafficked from the towns and villages to live the lives of slaves more than a thousand miles away from their homes.

We wanted to find out why.

Much ink has been spilled on the growing trend of global land grabs – land purchased en masse in developing countries like Ethiopia by foreigners mainly for agricultural export. But along with land, investors often also gain the right to use local water, and sometimes with little consideration for local livelihoods. Fred Pearce recently looked into these “water grabs” in a series for National Geographic.

“However rapid change has been over the past couple decades, the rate of change will accelerate in the future,” states the newest quadrennial report from the National Intelligence Council (NIC), Global Trends 2030: Alternative Worlds. Released late last year, the report identifies the “game-changers, megatrends, and black swans” that may determine the trajectory of world affairs over the next 15 years, including demographic dynamics and natural resource scarcity. [Video Below]

Cooperation, not conflict; that’s the theme of this year’s World Water Day. Collaboration over water has been the rule rather than the exception over the past 70 years, UNESCO explained in the launch of their International Year for Water Cooperation initiative earlier this year (which the rest of the UN is thoughtfully supporting).

But the fact that there’s need for such an initiative shows that water conflict and other water issues are not far from the minds of global policymakers. Scarcity, drought, climate change, food security, disease – water impacts people and their governments in so many ways. Here’s a rundown of some of our best related posts.
