In May 2011, two weeks before I was scheduled to start research in the region, a Mongol herder named Mergen was hit by a mining truck while protecting his pastureland in Xilingol, Inner Mongolia. He was dragged 140 feet and killed. His death sparked a month of protests.

For all its flaws, the United Nations remains the only plausible forum for engaging broad global challenges like sustainable development. The most important environmental achievements of the past 40 years – the rise of environmental awareness, the birth of key ideas such as sustainability or the common heritage of humanity and the most important global treaties for environmental protection – all bear the UN stamp in one way or another. We could have added environmental human rights to that legacy last month, but we failed.

The board of the United Nations’ lead organization on trade and development, called UNCTAD, released an assessment of Gaza’s development challenges during their annual meeting in Geneva this month and the news is not good. In 2012, the UN warned that a “herculean” development effort would be to keep pace with Gaza’s rapid population growth. Since then, more fighting with Israel has made things worse, particularly with regard to water and food security. Ninety-five percent of the water from Gaza’s coastal aquifer is unsafe for drinking without treatment, the report says. Contamination and over-extraction may even render it unusable by next year and damage may be irreversible if not addressed in the next five years.

According to recent polling, climate change is seen as the single most threatening international challenge around the world, and there’s evidence that all that worry is taking a psychological toll. Adding to droughts, floods, extreme weather, and die-offs, psychologists are observing higher levels of anxiety, depression, and post-traumatic stress disorder in certain areas and professions. Even people who do not actively stress about global warming or view it as a major threat may still suffer psychological trauma from its effects.

More than 80 percent of the estimated 42 million people living in Central Africa’s Lake Victoria Basin depend on fishing or farming for survival. Given this overwhelming reliance on natural resources, the lake’s deteriorating condition – driven by climate change, agriculture, pollution, deforestation, overfishing, and industrialization – has far-reaching implications.

Some of the world’s most crucial ecosystems can also be found in the most conflicted areas. The most progressive peace agreements in these circumstances sometimes include conservation protections, but fewer still include women – and that’s a an article in Peace Review by Conservation International’s Brittany Ajroud, Kame Westerman, and Janet Edmond.

Water is being used as a weapon of war on one of Syria’s deadliest battlegrounds, says the International Committee of the Red Cross (ICRC) and its local affiliate, the Syrian Arab Crescent, in a new video.
