The intelligence community’s landmark Global Water Security assessment in 2012, warned of major water-driven challenges to U.S. national security. The combined assessment of several intelligence agencies foresaw many challenges to U.S. policy objectives and national security arising from protracted drought, declining water quality, and more natural disasters in countries important to U.S. interests. The intelligence community further warned of rising social instability, cross-border tensions, and a steady drain of resources away from other development objectives. These warnings have proven prescient.

In a recent article published in PLOS ONE, Juliann E. Aukema, Narcisa G. Pricope, Gregory J. Husak, and David Lopez-Carr address the impacts of climate change and population growth on areas with vulnerable ecosystem services and biodiversity, and in reverse, how degraded ecosystem services effect vulnerable populations. The authors analyze locations between 50 degrees latitude north and south that had changing precipitation patterns in the past 30 years.

It’s often assumed that in the modern era, food security is an achievable goal. But between 2007 and 2008, a confluence of conditions shook the international food system to its core, fueling unrest and riots in more than 40 nations around the world.

MEXICO CITY – On bad days, you can smell the stench from a mile away, drifting over a nowhere sprawl of highways and office parks.

The effects of climate change combined with breakdowns in governance are leading to food insecurity “on a scale that we’ve rarely seen,” said Alex de Sherbinin, associate director of Columbia University’s Center for International Earth Science Information Network, at the Wilson Center on January 26.

In the first half of last year, 26,000 unaccompanied children were apprehended by U.S. law enforcement trying to cross the southern border. Most came from Central American states like El Salvador, Guatemala, and Honduras. Such displacement is just the tip of the iceberg in terms of migration in the region. Many more are moving from rural to urban areas and into neighboring countries seeking opportunity and fleeing violence.
