Since the end of World War II, the number of wars between states has declined significantly, but the number of intrastate civil conflicts – as seen in Syria and Afghanistan – has increased.

The United Nations Environment Program is highlighting the battle by Iraqi forces to reclaim Mosul from the Islamic State as the latest instance in the complex but very real linkage between military conflicts around the world and extreme environmental degradation.

Have something to say about the U.S. government’s approach to water around the world? Here’s your chance. The Department of State has issued a public call for comment on its global water strategy. An open session was held in Washington last Friday, but written comments can be submitted until November 12.

There may not have been a single question about climate change in the 2016 presidential debates, but it remains a hotly contested, partisan issue for many in the United States. That climate change is happening and requires a response is not up for debate within the upper echelons of the U.S. military, however.

Since its adoption in December 2015, United Nations Security Council Resolution 2250 on youth, peace, and security has been hailed as the first of its kind to recognize young people as meaningful drivers of change through its explicit encouragement of youth leadership at all levels of conflict prevention and peacebuilding. “It’s a testament to the fact that global youth today can have a real meaningful impact on the big issues of today, in the big arenas where discussions are happening,” said Andy Rabens, a special advisor on global youth issues for the U.S. Department of State, at the Wilson Center on October 6.

The world is undergoing a period of demographic transition which presents both opportunities and challenges for governments. A report by the Atlantic Council’s Mathew Burrows, formerly of the National Intelligence Council, Reducing the Risks from Rapid Demographic Change, examines the changes in population structures across high-, upper-middle-, lower-middle-, and low-income countries.

On October 13, the United Nations General Assembly appointed Antonio Guterres as the next UN secretary-general. When the former prime minister of Portugal and high commissioner for refugees begins his term in January 2017, he will face a world of increasing climate and security crises. In a Wilson Center NOW interview and op-ed for The Daily Climate, Wilson Fellows Ruth Greenspan Bell and Sherri Goodman express optimism in Guterres’ ability to address these interconnected challenges and provide insight on the role of institutions like the United Nations in fighting climate change.
