On my first tour of a Cambodian minefield in 2010, the demining supervisor of the platoon of deminers brought me through a tapioca field where heavily armored men and women stood in lines. I was not allowed beyond the bright red signs with skulls and crossbones. Wearing bulletproof helmets, masks, and aprons, they slowly and tediously walked through the field, using a metal detector to sweep the ground in front of them, the sun reflecting off the long plastic visor. To avoid the heat of the Cambodian sun, they began their work early in the morning. In the golden hour of sunrise as dawn gilded the fields, the sounds of a distant Buddhist temple surrounded us with chanting. I commented on how beautiful it was.

Thirty years of research underlies the realization that climate change poses substantial national, international and human security risks, but analysts have only recently shifted their focus toward how to simultaneously build peace in post-conflict environments and grapple with the dual challenges of mitigating and adapting to climate change. In a recent article in World Development article, we propose what causal pathways can simultaneously facilitate climate change adaptation, increase resilience, improve natural resource governance, and build more sustainable peace. 

“Gui Jie” in Beijing, meaning Ghost Street, is dedicated to crayfish and is filled with towering bright red crayfish statues. While it might just seem like a show for tourists, the Chinese are responsible for 90 percent of the world’s crayfish consumption and crayfish is on menus throughout the country. Between 2006 and 2016, crayfish production more than tripled to 850,000 tons. Surprisingly, crayfish is not native to China but the Chinese began raising them when aquaculture began expanding in the 1980s. 

Cambodia’s lush Prey Lang rainforest is abundant with animals, insects and birds, including endangered species, and diverse types of forests. It also provides resin tapping and other sources of livelihood for some 250,000 people, many of whom are Indigenous Kuy, living within or adjacent to the forest.

Feeding all the fish grown in aquaculture remains a challenge in China, the U.S. and elsewhere. Aquaculture currently uses 75 percent of global fish oil supplies and researchers estimate that the demand for forage fish will exceed the ocean’s supply by 2037. In this month’s top post, Karen Mancl discusses the need for policy interventions to halt the overharvesting of oceans for fish feed and to ramp up the use of alternative fish feeds such as insects and algae.

The takeover of Afghanistan by the Taliban not only threatens people’s lives, security, and fundamental freedom, but also significantly increases risks of water insecurity both immediately and in the long term. While our hearts and minds are with the people struggling for survival and freedom in Afghanistan today, we should not forget that the implications of Taliban rule will add yet another challenge to the long-term future of the Afghan people, and possibly also to the entire region’s stability.

With white sandy beaches, cerulean waters, and lush jungles, Indonesia’s Raja Ampat Islands are some of the world’s most beautiful islands—and currently under threat from a growing plastic waste crisis. Covering 40,000 square kilometers of land and sea off the northwest tip of West Papua, Raja Ampat lies at the intersection of the Indian Ocean and Pacific Ocean tides in a biodiversity hotspot known as the Coral Triangle. 

In the United States, approximately 10 to 15 percent of known pregnancies end in miscarriage. But this doesn’t capture the full picture. In reality, studies show that as many as half of all pregnancies may end in miscarriage, with the vast majority occurring before people realize they are pregnant. A miscarriage is defined as pregnancy loss before 20 weeks gestation. While some health conditions such as autoimmune disorders, polycystic ovary syndrome (PCOS), and diabetes can exacerbate the risk of having a miscarriage, the exact causes of pregnancy loss are largely unknown.
