At 1.8 billion strong, the current generation of 10 to 24 year olds is the largest in human history. Approximately 90 percent of these adolescents live in less developed countries. This poses an unprecedented challenge for health systems and social policies which largely struggle to meet the unique needs of young people, according to a new Lancet commission.

After more than a decade studying the wide-ranging effects of poor nutrition on children, former Wall Street Journal reporter Roger Thurow is outraged. Now he wants to inspire action.

Over the past decade, the number of undernourished people around the world has declined by around 167 million, to just under 800 million people. However, this positive trend glosses over a stark reality: Food insecurity is increasing in the world’s mountains. This pattern has been under-recognized by development experts and governments, a dangerous oversight with far-reaching social and environmental repercussions.

How will climate change affect you? Probably through water.

That’s the major message of a new World Bank report that finds the ways governments treat water can have a profound effect on the economy.

Today, new nations are pursuing civilian but dual-use nuclear capabilities, the threat of non-state actors seeking nuclear materials may be growing, and countries continue to debate proper ways to enhance nuclear safety, security, and nonproliferation systems to keep up with the pace of change. At the same time, governments worldwide are having difficulty managing the effects of a rapidly changing climate, such as more damaging natural disasters and resource stress. The relationships among nuclear, climate, and security risks are growing more complex and interconnected, and these issues are likely to begin converging in new ways. By early 2016, it has become clear that the international community must take a fresh look at the ways in which they are likely to connect and potentially collide in the years ahead, and foster deeper dialogue on what should be done about it.

Ashraf and Shazia use the word “guilt” often.* Their voices tremble as they rewind to the day when they read an article in an Indian magazine, Manorama, that opened their eyes to the reality of khatna – the practice of female genital mutilation among their community. “We felt guilt – immense, powerful guilt – when we realized that this was not needed, that we didn’t need to put our elder daughter through this,” the parents say. “We had no idea this was just going on, prevalent, generation after generation.”

According to political demographers, who study the relationship between population dynamics and politics, two characteristics when observed together provide a rather good indication that a state is about to shed its authoritarian regime, rise to a high level of democracy, and stay there. Myanmar has both.

Post-war countries are among the most difficult policy arenas. The challenge is not only to stop violence and prevent violence from rekindling, but moreover to help countries reset their internal relations on a peaceful path. Increasingly, researchers and practitioners are interested in the potential of natural resources in post-war settings in the hope that good governance and sustainable management can contribute to this reset. Indeed, the international community acknowledged the relevance of the link between peaceful societies and environmental issues by including both in the Sustainable Development Goals.
