On Son Island in Vietnam’s Mekong Delta, Le Trung Tin scatters fish feed into his ponds, where dozens of snakehead fish leap through the surface in synchronised bursts. “I taught them how to do that,” he says proudly, tossing another handful of feed at his fish.

The scene looks idyllic, but Le’s fish farm is a reluctant response to an escalating crisis. For decades, he made his living fishing the Hau River, a distributary of the Mekong. But in recent years, plastic waste clogged his nets and strangled the fish. “I had no choice but to stop,” he says. “Everything was tangled – trash, nets, even the fish themselves. It was hopeless.”

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.

Safe water, sanitation, and hygiene (WASH) are vital for human well-being. However, 1 in 3 people (approximately 2.2 billion) still lack safe drinking water, 4.2 billion do not have access to safely managed sanitation services, and 829,000 people die annually from unsafe water and related sanitation and hygiene around the world.

As climate change threatens the stability of ecosystems around the world, the preservation of forests is seen as a “win-win” solution to curbing planet-warming emissions while producing value for developing country economies.

Developing countries are in a pitched fight against the effects of climate change, and women, playing prominent roles in agriculture and household resource collection, are “at the front lines in the battle,” writes UN Framework Convention on Climate Change Executive Secretary Christiana Figueres, in a new report.

Somewhere off the coast of Thailand, “ghost ships” bump and crash along the choppy waves scrapping the sea floor with nets that spare nothing. Pulling up these illegal hauls in shifts that sometimes last 20 hours are thousands of migrant fishermen, many of whom have been forced into indentured servitude or kidnapped. Far from shore on unregistered boats, they have little hope of escape and face daily abuse and squalid conditions. More recently, some captains have turned to trafficking Rohingya fleeing persecution in Myanmar, pressing some into service, extorting others, and taking sex slaves.

In 2003, the United Nations General Assembly declared 2005 to 2015 to be the decade of “water for life” as a way to encourage countries to reach their water-related targets under the Millennium Development Goals. In summing up the last 10 years, it was noted that water cooperation had been promoted widely, featuring at international fora and in government initiatives and development agendas. Water cooperation is described as having the potential to enable peace and sustainable development. However, just as focusing on “water wars”  might undermine the everyday challenges of securing safe and adequate supplies of water, focusing only on “more cooperation” may well simplify the problem at hand.
