Peru is tackling water scarcity with nature-based solutions, leading the way in Latin America

Even in this humid tropical climate, she remembers when some 20 years ago there was such little water that services to the city were frequently cut off, angering the entire city. “There was […]
Water as Part of the Climate Solution
The intersection of freshwater and climate is a frequently ignored but critical element of the climate problem, according to a new study from Sweden that explores the link and offers solutions that will help lower emissions.

SANTA BÁRBARA, Chile — The Bío Bío River is the second-longest in Chile, forming in the Andes near the Argentine border and running 380 kilometers (240 miles) northwest before emptying into the Pacific.

For water quality, even a sliver of riverbank forest is better than none
Trees and plants along the banks of waterways are more than picturesque. They serve as a line of defense, absorbing pollutants and keeping harmful runoff out of rivers and streams.

A new method assesses health of Chile’s headwaters, and it’s not good news
Follow any river to its upper reaches and you will encounter the headwaters, the flowing streams that join to carry water, nutrients and life to downstream ecosystems and economies. Troubles here, at the river’s origins, quite literally trickle down. Headwaters are complex and notoriously difficult to study, but given their vital role, understanding where and […]
