Last year, the International Committee of the Red Cross (ICRC) celebrated 150 years of their mission to “protect the lives and dignity of victims of war and internal violence.” Though this mission hasn’t changed in the past century-and-a-half, the nature of conflict and crisis response has. [Video Below]

As the earth’s surface grows hotter and precipitation becomes more variable due to the impacts of climate change, the world is in need of solutions to more effectively store water supplies. One potential solution is deceptively simple: store water in aquifers below the ground.

Military leaders should be very concerned about climate change – that’s the message of a new report released this week by the CNA Corporation’s Military Advisory Board.

The Intergovernmental Panel on Climate Change’s fifth assessment, which has been rolling out in stages since last September, confirms a crucial divide in current climate thinking: efforts to adapt and mitigate to climate change are often considered separately from the vulnerability of people.

Outside of donor and humanitarian aid, South Sudan’s economy is almost entirely dependent on the oil sector – and that sector is in crisis.

What is the future of population and climate change research, and how can this research impact international policy? In a special issue of Population and Environment, environmental and social scientists look at these questions. “One of the most exciting developments in the climate change research community at present is the development of a new generation of climate scenarios,” write Adrian C. Hayes and Susana B. Adamo in the introduction. These can help facilitate more interdisciplinary research.

Democracy is fickle. Many of the competing theories on the best ways to foment and consolidate plural, inclusive governance or predict its rise and fall focus on political and economic forces. Yet a small group of demographers have explored population age structure as a catalyst for and reflection of a host of changes in societies that can affect governance.

The emerging subfield of “security demographics” is interested in how demographic trends, such as youth bulges, high or low fertility rates, and sex ratios affect the security and stability of nation-states and regions. In our research, Andrea Den Boer and I have attempted to show that abnormally high sex ratios – situations where there are significantly more men than women – have been a security concern in the past and may affect security and stability in the future.
