Wildfires are growing more frequent and severe across the western United States, and California's Sierra Nevada is ground zero. Decades of fire suppression have left these forests overstocked and vulnerable to catastrophic fires, drought and pest outbreaks.

Beyond destroying homes and infrastructure, high-severity wildfires release massive amounts of carbon, degrade water quality, erode soils, reduce timber supply and fill the air with hazardous smoke that threatens public health.

Only 20 years since undergraduate instruction began, UC Merced is a recognized leader in conducting academic research, developing young minds for career success and driving economic growth, the university’s chancellor said Wednesday.

BioSCape, a multinational research project co-led by UC Merced, the University at Buffalo and the University of Cape Town, which monitored Earth’s biodiversity from the air, has received a Group Achievement Award as part of the 2024-25 NASA Honor Awards.

A new documentary also showcases the project’s impressive results.

Kathy Chau believed she knew what her future would look like. The first in her family to attend college, she had long been advised to aim for a safe and stable job — one that might not light a fire in her soul but would pay the bills.

“I resigned myself to working a corporate job. I didn't like the sound of it, but I didn't hate it, either,” she said.

Nearly half of the world’s worst wildfire disasters have occurred in just the past decade, new research from UC Merced’s Fire Resilience Center shows.

Storing carbon in forests is an essential, nature-based buffer against climate change. Yet forests packed with too many trees increase the threat of severe wildfires, which are becoming all too common in warmer, drier conditions.

A team of UC Merced and collaborating researchers evaluated the tradeoffs between two seemingly opposing scenarios:

• Trees are critical because they pull carbon dioxide from the air and store it in their trunks, preventing carbon from adding to greenhouse effects that trap heat and warm the atmosphere.

Researchers at UC Merced and the University of California Agriculture and Natural Resources installed an irrigation system powered by artificial intelligence to deliver the precise amount of water needed and measure the results.

When Professor Asmeret Asefaw Berhe arrived at UC Merced in 2009, she and her husband, Professor Teamrat Ghezzehei, were leaving major research institutions to join a brand-new campus in California’s Central Valley. It was a leap of faith — one made easier by the Sierra Nevada Research Institute.

As the Hellman Fellowships celebrate their 30th year, three more researchers, one from each of UC Merced’s schools, have joined the prestigious ranks of recipients.

Electrical engineering Professor Qian Wang, sociology Professor Meredith Van Natta and Earth systems Professor Adeyemi Adebiyi will receive funding through their fellowships for projects they have proposed.

Lightning from thunderstorms rolling through Central California on Sept. 2 ignited numerous wildfires, including several large fires in the Sierra Nevada foothills that had burned more than 19 square miles by Wednesday morning. The California Governor’s Office of Emergency Services recorded more than 9,000 lightning strikes in a single day.

Lightning is a major source of wildfire ignition in the western United States every summer.
