Featured side by side at the top of The New York Times home page recently were two stories: one on the United States and China, the world’s largest producers of carbon emissions, committing to a global climate agreement, another on how rising seas are already affecting coastal communities in the United States.

Rivers have shaped the Western Balkan Peninsula’s characteristic landscape and played an important role in its history. Following the violence of the Yugoslav secession wars in the 1990s and the creation of six new nations, the number of transboundary river basins doubled from 6 to 13. In Kosovo, where independence remains a question, the water sector is a microcosm of tensions between ethnic Serbs and Albanians. The challenge of water resource management exists not only over the province’s contested national boundaries with Serbia, but between divided ethnic groups within the territory.

The Nile River is shared by 11 countries, for which it is vital for food and energy production, freshwater, and as a means of transportation. Sharing the resources of the Nile has, however, been politically difficult. Recently, the construction of the Grand Ethiopian Renaissance Dam has caused a major dispute with downstream Egypt which fears the dam will affect water flow in its own territory.

Overfishing by foreign fleets in West Africa is leading to devastating social and economic consequences. In a report from the Overseas Development Institute, an independent think tank based in London, researchers use satellite data to assess the scale of two kinds of illegal, unreported, and unregulated fishing: “reefers,” or large-scale commercial vessels receiving and freezing fish at sea and at port, and large refrigerated container ships that are registered in countries with less stringent enforcement regulations than that of the ship’s owners.

The International Expert Forum (IEF) is a series of seminars meant to facilitate dialogue between experts and policymakers on peace and security. Meeting in Stockholm this past May, the forum explored the connections between environmental issues, peacebuilding, and conflict while considering how environmental governance can aid in peacebuilding. The summary brief produced after the forum provides a useful snapshot of a fast-changing field of study.

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.

Last month, the world came to Copenhagen to focus on how to achieve the Sustainable Development Goals (SDGs) for girls and women. The Women Deliver Conference, the largest gathering on girls’ and women’s health and rights in the last decade, was a huge success. Convening over 5,700 likeminded people from 169 countries was important to reenergize the movement and inspire action. Preaching to the converted is sometimes important. But now it’s time to focus on those who are not yet converted.

A report by the European Union on global food security finds 240 million people are in food stress thanks to conflict, refugee situations, flooding, drought, and El Niño. Part of a 2012 commitment by the EU to better target the root causes of food insecurity, the report analyzes the hunger situation in 70 countries and provides deeper analysis for 20.
