India is one of the most water-challenged countries in the world, from its deepest aquifers to its largest rivers. Groundwater levels are falling as farmers, new urban residents, and industries drain wells and aquifers. What water is available is often severely polluted, and the future may only be worse, with the national supply predicted to fall 50 percent below demand by 2030.

Though the bull market for metals and energy may be ending, global food prices remain stubbornly high. The inflation-adjusted FAO Food Price Index is down from the near historic heights of 2007-08 and 2011 but still higher than at any point in the previous 30 years, putting a brake on several decades of progress in reducing world hunger.

Climate change and youthful demographics can combine to create security risks in already fragile contexts, according to a new report commissioned by UNICEF UK and co-authored by the London-based research organizations International Alert and the International Institute for Strategic Studies.

The story of Uma Tudu captures the endless cycle of poverty, violence, and suffering faced by too many girls in the northeastern Indian state of Assam.* At 16, following floods that destroyed her village, she traveled more than 1,600 kilometers to Delhi, lured by the promise of a good job and a good life.

Last week, the Islamic State’s ignorance of the role of demography in their local success may have led them to overplay their hand. Seeking to dissuade Jordanians from following their government in actively supporting the alliance arrayed against them, they executed a captured Jordanian pilot in horrendous fashion, burning him alive. Yet Jordan is not like Syria or Iraq, where violence against westerners or Shi’a or other minorities has helped split people from their allegiance to the government. Instead, this act of violence seems to have unified Jordan’s Sunnis against the Islamic State for their actions against a fellow Sunni Muslim. Jordan has expanded its assault, striking dozens of targets in Iraq for the first time.

Stepping away from herds of cattle, subsistence farms, and other responsibilities at home, roughly a hundred Kenyan villagers traveled overnight by bus from the Tana River Delta to Nairobi in February 2011 for a hearing at the national high court. The claimants declared that the lack of a “comprehensive land use master plan” infringed on the rights of the region’s people, and called for the prohibition of further land and resource development until such a plan was negotiated.
