In the Peruvian Andes, where cropland is irrigated and water availability is variable at best, knowledge of highland hydrology is crucial to survival. However, until recently, the locals did not have adequate information to be able to use their water efficiently. So the community worked with a nonprofit to develop a non-specialist/non-researcher run data-gathering project to monitor the water in the region to optimize its use: in short, they developed a citizen science project.

By 2050, the UN estimates that 52 percent of the world’s population will be at risk for water insecurity. Climate change is threatening water availability through increased temperatures and drought, unpredictable rain, and the growing threat of more pollution. Globally, most wastewater reenters the water cycle without being treated, introducing dangerous unseen particles including pharmaceuticals, diseases, and larger waste products such as plastics.

Years ago, Mohamed’s family had enough to eat, despite being poor. His daughter owned a vegetable stall at a bustling market in northeastern Nigeria. The family had options: during the dry season, when Lake Chad was shallow, Mohamed could farm; and during the wet season, he could fish or graze his cattle.

“If you go to some Taiwan beaches, you can see snow,” said Chieh-Shen (Jason) Hu, Ocean Initiative Coordinator for Taiwan’s Society of Wilderness, a 6,000-member organization similar to Sierra Club. Hu was referring to pervasive Styrofoam marine debris from western Taiwan’s oldest industry, oyster aquaculture.

International political boundaries are arbitrary creations. Today’s borders are better described as imaginary lines on maps, rather than hard barriers between states. Often using mountains, rivers, or other geographical landmarks, modern borders are entrenched in historic tradition rather than logic and fact. As a result, today’s international borders are poorly equipped to handle modern challenges, in particular climate change, which has already begun to threaten the most important state resource, fresh water.

“If you woke up one morning and found the taps in your house were dry, the first thing many of us here would do is pick up our phone and call the utility,” said Gordon Mumbo, Team Leader for Sustainable Water for the Mara River Basin, Winrock International. But for people living in the Mara River Basin, if their taps run dry, there is no utility to call, said Mumbo. Their only choice is to grab the water container and head down to the river where water quality may be poor. Mumbo spoke at the September 30^th event, “Hidden Forces: The Role of Water in Economic Prosperity,” part of the “Water Security for a More Resilient World” series co-hosted by the Wilson Center, Winrock International, and the Sustainable Water Partnership.

Water is so scarce these days in Murrurundi, a drought-tested town in the northern reaches of New South Wales, that it arrives by truck.

Murrurundi Dam, an off-channel reservoir that draws from the Pages River, is functionally dry. An emergency well provides a little local water, but half of the small community’s supply is now trucked in.

“I’ve never seen the Pages River this low,” Daele Healy, who has lived in town for 15 years, told Circle of Blue. “There’s just no water visible at all. Not even little ponds.”
