The state of the global environment is terrible – and deteriorating. The globalization of industrial production and the consumptive habits of 7 billion people have created the Anthropocene, a geologic age in which the actions of humans are the primary determinant of the Earth’s natural systems. This shift creates a profound new form of environmental interdependence, of which climate change is only the most salient example.

Water scarcity has contributed to an “arc of instability” characterized by conflict and displacement that stretches from West Africa to the Middle East, said a panel of experts at the Wilson Center on March 1. Two authors from an upcoming compilation of case studies on water security and violent conflict by World Wildlife Fund gave overviews of challenges in Nigeria and Iran and recommendations for U.S. engagement.

Forecasts of future climate conditions are fairly good, but forecasts of future socioeconomic conditions are another story. To get a sense of how climate change will impact society, many resort to simply layering future climate conditions on top of current socioeconomic conditions. That’s a mistake, write Wolfgang Lutz and Raya Muttarak in Nature Climate Change. “We see little value in the purely hypothetical exercise of assessing potential impacts of the future climate on a society that will not exist in the future.”

In a brief published by the Stanley Foundation, Cullen Hendrix explores how “the degradation and overexploitation of renewable sources…and unequal access to these resources” can make societies more or less susceptible to experiencing mass atrocities. Hendrix proposes that “demographic-environmental stress” is most likely to contribute to mass atrocities (genocide, war crimes, or crimes against humanity) in agricultural societies that have a high level of group identity-driven politics and economics, exclusionary political institutions, political actors that deprive certain groups, or when governments have low legitimacy.

The waters of Lake Chad sustain 70 million people in four countries. Beginning in the 1970s, the 25,000-square-kilometer lake began shrinking due to excessive drawdown for agriculture and mining. Now only 10 percent remains. The dwindling water supply devastated food production and fostered massive economic and political tensions. Many experts credit the worsening conditions for contributing to the rise of Boko Haram, an extremist group that has killed 20,000 people and forced 2.3 million more to flee.

More than 40 years ago, the Soviet Union attempted to harness hydropower to modernize Afghanistan. Between 1960 and 1968, they poured money and technical knowledge into the 100-meter Naghlu gravity dam outside Kabul and a village for its workers called Sharnak. Although the town has been damaged and the boons of modernity remain elusive for many Afghans, the dam remains a crucial source of power for the capital and is the largest power plant in the country with an installed capacity of 100 megawatts.
