Growing beside sleek vertical solar panels, lush green pepper plants flourish at the height of summer. A team of UC Davis researchers are analyzing an agrivoltaics system that combines farming with solar technology to boost crop growth and promote sustainability.

This innovative approach, according to UC Davis Associate Professor Majdi Abou Najm with the Department of Land, Air and Water Resources, could be a valuable solution as California faces a hotter, drier climate.

Wading through flooded rice fields, a team of UC Davis students and researchers release thousands of shimmering fish into the water. These small golden shiners hold the promise of significant contributions to the dual challenges of climate change mitigation and sustainable food production.

Satellite data from across California’s landscapes reveal an increase in nitrogen dioxide levels in remote forest areas, and wildfire and soil emissions are likely the reasons why, according to a paper from University of California, Davis, published today in the journal Environmental Research Letters.

From Fort Bragg to the Mojave Desert – a group of UC Davis students spent part of their summer analyzing the soils of California ecosystems. For graduate student Yuanxin Ji, the experience inspired him to craft a heartfelt song with lyrics about the intricate world of soils set to a catchy tune.

Xiaoli Dong is putting biological soil crust on the climate change research map, a project for which she received UC Davis’ single Early Career Faculty Award for Creativity and Innovation for 2023.

The university gives one or two of the $40,000 awards annually, funded by an endowment set up by anonymous donors.

A team of UC Davis doctoral and undergraduate students have something to celebrate as the fall quarter comes to a close. UC Davis sent a team to the Region 6 (southwest) Collegiate Soil Judging Competition, where groups are scored on their ability to describe and classify soils and landscapes.

Wine grapes are susceptible to subtle changes in temperature and precipitation, making them particularly vulnerable to the effects of climate change. 

Regenerative agriculture, which uses holistic farming and grazing practices to strengthen soil health and crop productivity, may help grape vines become more resilient to changing climate conditions. However, more research is needed to increase adoption of regenerative agriculture practices on vineyards. 

Joanne Emerson is a virus hunter. She has tracked viruses in a hypersaline lake in Australia, analyzed viral communities in the thawing permafrost of Sweden and contributed to studies of oceanic viruses that infect marine microorganisms.

By moving beyond the surface level and literally digging deep, scientists at the University of California, Davis, found that compost is a key to storing carbon in semi-arid cropland soils, a strategy for offsetting CO2 emissions.
