University of Saskatchewan, NASA team up on global water survey
August 25, 2017 08:28 AM - University of Saskatchewan

Pardon the pun, but Canada is practically overflowing with freshwater.

And, believe it or not, that abundance causes problems for water researchers.

“Canada is blessed with more freshwater than anywhere else in the world, but there’s no way you can put sensors in to monitor everything,” said Al Pietroniro, executive director of National Hydrological Services, an adjunct professor with the University of Saskatchewan and member of the Centre for Hydrology. “It’s too big.”

Dramatic changes needed in farming practices to keep pace with climate change
August 4, 2017 02:24 PM - Lancaster University

Major changes in agricultural practices will be required to offset increases in nutrient losses due to climate change, according to research published by a Lancaster University-led team.

Small hydroelectric dams increase globally with little research, regulations
January 22, 2018 04:45 PM - Michelle Ma, University of Washington

Hydropower dams may conjure images of the massive Grand Coulee Dam in Washington state or the Three Gorges Dam in Hubei, China — the world’s largest electricity-generating facility. But not all dams are the stuff of documentaries. Tens of thousands of smaller hydroelectric dams exist around the world, and all indications suggest that the number could substantially increase in the future.

The spirit of collaboration aboard Gulf of Mexico cruise
July 24, 2017 08:23 AM - NOAA

This summer, NOAA and partner scientists will conduct their most collaborative ocean acidification sampling of the Gulf of Mexico yet. Set to depart today, July 18th, the Gulf of Mexico Ecosystems and Carbon Cruise (GOMECC-3) will travel through international waters with 24 scientists from the United States, Mexico and Cuba on board.

The Nitrogen Problem: Why Global Warming Is Making It Worse
August 8, 2017 03:30 PM - Yale Environment 360

It is a painful lesson of our time that the things we depend on to make our lives more comfortable can also kill us. Our addiction to fossils fuels is the obvious example, as we come to terms with the slow-motion catastrophe of climate change. But we are addicted to nitrogen, too, in the fertilizers that feed us, and it now appears that the combination of climate change and nitrogen pollution is multiplying the possibilities for wrecking the world around us.

A new NOAA tool is helping to predict US droughts, global famine
December 5, 2017 08:14 AM - NOAA

Agriculture is the economic engine that powers the Great Plains, the vast stretch of treeless prairie that covers parts of 10 states – and where the next drought can appear with little warning.

Now there’s a powerful new tool to help provide farmers and ranchers in the arid western United States critical early indications of oncoming droughts, and its name is EDDI.

Urban floods intensifying, countryside drying up
August 16, 2017 08:15 AM - Wilson Da Silva, University of New South Wales

A global analysis of rainfall and rivers by UNSW engineers has discovered a growing pattern of intense flooding in urban areas coupled with drier soils in rural and farming areas.

Saline Lakes in Dire Situation Worldwide, Including Utah's Great Salt Lake
October 23, 2017 02:12 PM - Utah State University

Saline lakes around the world are shrinking in size at alarming rates. But what—or who—is to blame?

Projected Precipitation Increases Are Bad News for Water Quality
July 27, 2017 04:40 PM - Carnegie Institution for Science

If climate change is not curbed, increased precipitation could substantially overload U.S. waterways with excess nitrogen, according to a new study from Carnegie’s Eva Sinha and Anna Michalak and Princeton University’s Venkatramani Balaji published by Science. Excess nutrient pollution increases the likelihood of events that severely impair water quality. The study found that impacts will be especially strong in the Midwest and Northeast.

Olive mill wastewater transformed: From pollutant to bio-fertilizer, biofuel
September 28, 2017 01:00 PM - American Chemical Society

Olive oil has long been a popular kitchen staple. Yet producing the oil creates a vast stream of wastewater that can foul waterways, reduce soil fertility and trigger extensive damage to nearby ecosystems. Now in a study appearing in ACS Sustainable Chemistry & Engineering, scientists report on the development of an environmentally friendly process that could transform this pollutant into “green” biofuel, bio-fertilizer and safe water for use in agricultural irrigation.
