In his speech on climate change and national security on November 10, Secretary of State John Kerry said climate change is already a “threat multiplier,” and that worse is to be expected if climate change continues unchecked. But the relationship between the environment and violent conflict is complex and often indirect. Researchers have been wrangling for years over the role that global environmental change plays in fueling conflict and state fragility.

The dark eyes and hair of the Pakistanis, Bangladeshis, and Afghans almost blend with the other migrants’. The brown skin tones are also not giveaways, but ask them where they come from, and you notice the hesitation – trying hard to blend into the crowd of Syrian migrants at Europe’s border crossings, afraid of being spotted and sent back.

In the midst of a minefield on day two of Desert Storm Task Force Ripper, Marine Corps Operations Officer Richard Zilmer stepped out of his armored personnel carrier, squinted up at the sky, and saw nothing but black from horizon to horizon. Iraqi forces, trying desperately to blunt the attack of coalition armies, had set fire to hundreds of Kuwaiti oil wells and oil-filled trenches.

A recent article by Malcolm Potts, Aafreen Mahmood, and Alisha Graves of the University of California Berkeley’s OASIS Initiative notes that family planning has an important role to play in building peace by increasing women’s empowerment and their agency. “The pill is mightier than the sword,” as they put it.

When war breaks out, what happens to the weather forecast? Violent conflict disrupts many essential services in developing countries and one of the most overlooked is meteorology, which has surprisingly big consequences for farmers, policymakers, and the aid workers who are there to help.

Scenario planning has a long history. The RAND Corporation employed it heavily in planning for potential U.S. responses to nuclear war and 16^th century Spanish Jesuit theologians pointed to the idea as proof of free will. But in many respects this powerful set of methodological tools for managing complexity and uncertainty remains underused, especially beyond the defense, intelligence, and business communities.

The board of the United Nations’ lead organization on trade and development, called UNCTAD, released an assessment of Gaza’s development challenges during their annual meeting in Geneva this month and the news is not good. In 2012, the UN warned that a “herculean” development effort would be to keep pace with Gaza’s rapid population growth. Since then, more fighting with Israel has made things worse, particularly with regard to water and food security. Ninety-five percent of the water from Gaza’s coastal aquifer is unsafe for drinking without treatment, the report says. Contamination and over-extraction may even render it unusable by next year and damage may be irreversible if not addressed in the next five years.

Water is being used as a weapon of war on one of Syria’s deadliest battlegrounds, says the International Committee of the Red Cross (ICRC) and its local affiliate, the Syrian Arab Crescent, in a new video.
