An estimated 1.8 billion people today are between the ages of 10 and 24 and 85 percent of them live in developing economies and/or fragile states. Such youthful age structures can lead to a number of challenges, including increased potential for instability, and countries with large numbers of young people must find ways to address their unique needs.

In July, thousands of people attended the 20th International AIDS Conference and the 2014 Girls Summit to work towards an AIDS-free generation and ending child and forced marriage. But such attention is rare; by and large, these girls are invisible to development efforts. [Video Below]

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.

In 1986, global nuclear weapons stockpiles peaked at nearly 70,000 warheads. By the beginning of 2013, there were just over 17,000, with only 4,400 kept operational. This dramatic reduction was the fruit of a negotiation process that began in the late 1940s. In spite of incredible tensions between the United States and the Soviet Union, negotiators were able to make progress once they focused on building trust with small, pragmatic steps, rather than starting with the complete elimination of all weapons. [Video Below]

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.

Since the early 1990s, the rising price of crude oil and other key natural resources – and the resulting drive by governments and private companies to extract those resources – has led to sharp conflicts in Latin America. At the core of these disputes is the clash between national economic interest and the rights of indigenous people inhabiting the land where most natural resources are located.
