In the sleepy northern Thai border town of Huay Luk, a community leader, Pornsawan Boontun, still remembers the day when villagers netted a Mekong giant catfish more than a decade ago. The fish weighed 615 pounds, and it surprised everyone since the elusive species has never been common in this stretch of river.

“Humanity is altering Earth’s life support system. Carbon dioxide emissions are accelerating; greenhouse gas levels are unprecedented in human history,” says a new video summarizing some of the most striking finds of the Intergovernmental Panel on Climate Change’s latest report. The climate system is changing rapidly, and it is “extremely likely,” the video quotes the IPCC, that humans are the central reason why.

Phan Dinh Duc leans against yellow sacks of freshly harvested rice. It’s a warm spring evening in Vietnam’s Mekong Delta, and Duc, a local farmer, is waiting for traders to arrive by truck to purchase his produce and sell it on commodities markets. Beyond him lies a vast checkerboard of rice paddies, each filled with water and bordered by a network of canals and roughly 10-foot-high earthen dikes. They enable year-round rice cultivation in an area where, a half century ago, vast floodplains typically lay fallow for half the year and farmers planted one annual rice crop that grew in tandem with seasonal floods.

“Today we have a golden opportunity to use respectful maternal care to break new ground at the intersection of health and human rights,” said Lynn Freedman, director of the Averting Maternal Death and Disability Program and professor of clinical population and family health at Columbia University, at the Wilson Center.

From the 2004 Indian Ocean tsunami to Superstorm Sandy, the last decade has seen an incredible array of natural disasters. Of course, disasters of all kinds are nothing new, but, thanks to the growing scale and interconnectedness of the human enterprise – and the damage we have done to the natural world – the frequency, scale, and consequences of today’s calamities are truly without precedent.

A well-known Chinese proverb describing the relationship between the central government in Beijing and its people says, “Heaven is high and the emperor is far away” (天高皇帝远, tian gao, huang di yuan). It’s not too far of a stretch to apply the same proverb to the current state of China’s environment sector, where relatively strong pollution control laws are poorly enforced on the ground.

As reproductive rights advocates reflect on their disappointment with the outcome of last week’s Rio+20 summit, it is encouraging to see that population, health, and environment (PHE) projects – which fundamentally connect women’s health with sustainable development – continue to sprout up around the world. The Population Reference Bureau (PRB) launched their community-supported PHE Project Map in March 2010, and since then, the map has grown to include 76 projects across three continents, and has been viewed more than 82,000 times.

Two decades after the Paris Peace Accord that ended the proxy war in Cambodia, the Mekong Basin has re-emerged as a region of global significance. The rapid infrastructure-led integration of a region some call “Asia’s last frontier” has created tensions between and among China and its five southern neighbors – Cambodia, Laos, Myanmar, Thailand, and Vietnam. Both expanded regional cooperation as well as increased competition for access to the rich resources of the once war-torn region have created serious environmental degradation while endangering food security and other dimensions of human security and even regional stability.
