Covering the 4,000 miles of California’s water canals could save billions of gallons of water and generate renewable power for the state every year, according to a new study.

Professor Marc Beutel and his graduate student Mark Seelos have been recognized for papers and a presentation on toxic mercury mitigation by the North American Lake Management Society.

Beutel, an environmental engineer, co-wrote two of a group of three papers named Best Paper of the Year at the 2020 North American Lake Management Society annual conference.

The millions of people affected by 2020’s record-breaking and deadly fire season can attest to the fact that wildfire hazards are increasing across western North America.

Both climate change and forest management have been blamed, but the relative influence of these drivers is still heavily debated. The results of a recent study show that in some ecosystems, human-caused climate change is the predominant factor; in other places, the trend can be attributed mainly to a century of fire suppression that has produced dense, unhealthy forests.

Two new projects designed and led by UC Merced researchers will address challenges facing many Californians — wildfire recovery and agricultural labor — but will also have global reach.

Soil biogeochemistry Professor Asmeret Asefaw Berhe has been recognized by the American Geophysical Union (AGU) as one of this year’s recipients of the Joanne Simpson Medal for Mid-Career Scientists.

One of the biggest challenges in managing crops, especially in large fields, is knowing how much water each section of a field needs. Determining that accurately is a cumbersome process that requires people to hand-pluck individual leaves from plants, put them in pressure chambers and apply air pressure to see when water begins to leak from the leaf stems.

That kind of testing is time consuming and means that farmers can only reach so many areas of a field each day and cannot test as frequently as they should.

Ward Eldredge warily monitored the fire’s progress. As curator of the archives of the Sequoia and Kings Canyon National Parks, he deliberated what would need to be done if the nearby Castle Fire continued its approach toward the parks’ headquarters.

The air around Three Rivers grew thick with smoke. It was looking bad.

“The fire had exhibited some very alarming behavior — long runs, great distances travelled,” Eldredge recalled.

School of Engineering professors Roger Bales and Martha Conklin have written a new article for The Conversation discussing the changes that need to be undertaken in land-management practices in California's mountain forests:

Since 2007, UC Merced researchers have been extremely productive in the Southern Sierra Critical Zone Observatory (CZO), delving into investigations of hydrology, climate change, geology, biology and more.

But the National Science Foundation, which funded the CZOs, is decommissioning the sites and has reconfigured the program around themed research clusters in a new program called the Critical Zone Collaborative Network (CZCN).

Bird species usually are counted twice a year by wildlife surveyors: once during the breeding season and again during the Christmas Bird Count .

New technology, however, is increasing the accuracy of bird population studies. A team of UC Merced researchers is developing a model to recognize bird calls.
