Tucked away in a recent New York Times story on military operations against ISIS by Iraqi special forces and the Kurdish Peshmerga was a brief description of what these troops discovered when they entered a village in Iraq that had been occupied by ISIS fighters. A naked woman, tied to a tree, who had been repeatedly raped by ISIS fighters. Another woman was discovered in a second village, similarly naked, tied down and repeatedly raped. The fighters, it appears, are “rewarded” by being allowed to have their way with captured women.

Is it possible to prepare for the unexpected? Could anyone have foreseen, for instance, a nuclear meltdown triggered by an earthquake-induced tsunami? Or a brutal band of transnational militants quickly capturing Iraq’s largest dam while attempting to establish a new Islamic caliphate? Perhaps not exactly, but that shouldn’t stop us from anticipating unlikely events, says Chad Briggs, a risk assessment expert and strategy director of consulting firm GlobalInt.

Nearly 1 billion people lack reliable access to clean drinking water today. A report by the Water Resources Group projects that by 2030 annual global freshwater needs will reach 6.9 trillion cubic meters – 64 percent more than the existing accessible, reliable, and sustainable supply. This forecast, while alarming, likely understates the magnitude of tomorrow’s water challenge, as it does not account for the impacts of climate change.

Amid stop-and-start ceasefires, the tally of death and destruction from the recent conflict in the Gaza Strip has begun. Whatever the final losses incurred – casualties and damage are considerable with estimates varying significantly depending on the source – Gaza’s youngest residents are likely to be most profoundly affected.

The fight for control over “the most dangerous dam in the world” is raging.

Since its capture by Islamic State (IS) militants on August 7 and subsequent attempts by Iraqi government and Kurdish forces to take it back, Iraq’s Mosul Dam has been one of the central components of the government’s surprising and rapid collapse in the country’s northern and western provinces. In fact, one might see the capture of the Mosul Dam as the moment IS ascended from a dangerous insurgent group to an existential threat to Iraq as a state.

Under international law, someone who flees their country because of conflict or persecution is a refugee, but someone who flees because of inability to meet their basic household needs is not. In the case of Somalia, it is increasingly difficult to make any meaningful distinction between the two.
