When Lake Poopó, Bolivia’s second-largest lake, dried up last December, an entire community lost their way of life and the scientific community cast their eyes to the map asking, where next? They didn’t have to look far. According to a report prepared by the World Lake Vision Committee, a collaboration between the International Lake Committee Foundation, the Shiga Prefectural Government of Japan, and the United Nations Environment Program, there are very few major lake systems that are not experiencing decreasing water quality, volume, biodiversity, or some combination of the three.

Over the course of 1,800 miles, 5,300 vertical feet, and at least five name changes, the Brahmaputra River, in sometimes turbulent outbursts, flows from the Tibetan plateau to the Bay of Bengal. Along the way, it crosses three countries, including major geopolitical rivals China and India, and supplies 90 percent of downstream Bangladesh’s freshwater during the dry season.

This month, Baskut Tuncak, the United Nations special rapporteur on human rights and toxics, presented the findings of his report on the effects of hazardous substances on the lives of children around the world to the 33^rd session of the Human Rights Council. His conclusions were bold and brave for their implications on conflict: States should take responsibility for cleaning up the toxic remnants of war and providing medical aid to affected communities and individuals.

Yesterday afternoon President Obama announced a new Presidential Memorandum on climate change and national security.

With the Sustainable Development Goals nearing their one-year anniversary, the global community continues to strive toward eradicating poverty by 2030. In order to achieve this ambitious target, many international development practitioners are embracing a more holistic approach to development, combining traditionally single-sector programming, like health or environment work, into more comprehensive efforts. But such integrated development is sometimes easier said than done.

Early this June, the Israeli government cut off drinking water to people living in the Salfit region of the West Bank and three villages east of Nablus. The consequences have been dire. Thousands of Palestinians have been left with no running water in their homes, and factories have been forced to shutter. The power imbalance that leaves Palestinians so vulnerable to Israeli turns of the valve plays out every year, made possible by Israel’s occupation of the water-rich Golan Heights in 1967. What is perhaps most surprising is that the situation persists.

A bipartisan group of defense experts and former military leaders are calling on the next administration to consider climate change as a grave threat to national security.

Accurate measurements of wealth are useful for developing more targeted and effective poverty reduction programs. Unfortunately, such metrics are few and far between, as data on economic livelihoods tends to be expensive to obtain, and once collected, is often unreliable.
