While climate change will undoubtedly have an impact on societies throughout the world, researchers are still debating whether or not it will cause conflict. John O’Loughlin, Frank D.W. Witmer, Andrew M. Linke, Arlene Laing, Andrew Gettelman, and Jimy Dudhia use a quantitative approach to tackle some of “sweeping generalizations” that have come to characterize this debate in a new study, “Climate Variability and Conflict Risk in East Africa, 1990-2009,” published last month in PNAS. They found that while there is “no statistically significant relationship” between precipitation and conflict, increased heat is correlated with more conflict in East Africa. Still, they also found that other factors, like population size and the space-time lag for violence, predict conflict more reliably than either of the climate-related elements.

“We know maternal health medicines are safe, we know they’re effective, we know they’re essential to keeping women healthy throughout pregnancy and childbirth,” said Kristy Kade at the Wilson Center on October 23. But lack of supply, poor quality, and misuse means they do not always help the women who need them. [Video Below]

When Augusto Conselho Chachoka and his neighbors heard that the world’s biggest coal mine was to be built on their land, a tantalizing new future floated before them. Instead of scraping by as subsistence farmers, they would earn wages as miners, they thought. The mining company would build them sturdy new houses, it seemed. Finally, a slice of the wealth that has propelled Mozambique from its war-addled past to its newfound status as one of the world’s fastest-growing economies would be theirs.

“When I embarked on this series, I approached it as an environmental reporter: What does a growing number of us and growing consumption mean for our planet?” said Los Angeles Times reporter Ken Weiss at the Wilson Center on October 9. Weiss, along with photographer Rick Loomis, recently completed a five-part series and multimedia presentation on global population that was the culmination of a year of research and travel through more than six countries. [Video Below]

As our ferry slowly made its way across the Pangani River along the northern coast of Tanzania, I sat next to a woman whose child held her hand tightly. The boy and I exchanged smiles, but we mainly admired the view. The late morning sun was behind us as the royal blue river met the cloudless sky.

Sub-Saharan Africa is a key region both for conservationists and those working for improved public health. Nine of the world’s 34 biodiversity hotspots are in sub-Saharan Africa, as are two of the five most important wilderness areas. This hotbed of biodiversity is also home to many of the world’s most rapidly growing populations and swelling urbanization, which is putting increased pressure on natural resources.

Access to safe water is often taken for granted in developed countries. But last week at the 22^nd annual conference of the Society of Environmental Journalists, panelists argued that the impact of dirty water on women’s health is an important but neglected story, not only in developing countries like Nigeria, but also in the United States.

Quantifying the role population plays in food security is “an incredibly powerful piece of information,” said Kathleen Mogelgaard in an interview with ECSP. Malawi is a case in point.

Mogelgaard saw the connections between food, population, and climate change firsthand on a recent trip to the southeast African country, whose population of 15 million is largely dependent on subsistence, rain-fed agriculture. “One in five children in Malawi is currently undernourished,” Mogelgaard said, and climate change paints a bleak picture for the future.
