Environment

There’s a whole world of activity beneath your feet. Soil holds a large proportion of Earth's biodiversity, and is the place where organisms interact with each other and with plants, serving important functions for their ecosystems.

Scientists know the whats and whys of using light, heat and electricity to direct chemical reactions toward an end goal. What’s less well understood are the effects mechanical force can have on chemistry.

Thanks to a three-year, $1.8 million National Science Foundation (NSF) grant, a team of researchers — including mechanical engineering Professor Ashlie Martini — are forming a new center for this emerging area of study.

By 2050, the U.S. population is estimated to grow to 400 million, and the world population to 9.1 billion, requiring a 70 percent increase in global food production.

UC Merced is one of four campuses across the country uniting to meet that challenge by harnessing the power of innovation and technology to develop precision agriculture for a sustainable future.

Summertime means fun in the water, but as temperatures increase, algal blooms can grow in freshwater and marine ecosystems.

Some algae are natural and life-giving, while others are the result of life out of balance and can have harmful effects. Consisting of bacteria and tiny plankton, they arise quickly and alter the ecosystem by consuming available oxygen, killing fish.

About 4.5 billion people around the globe do not have access to adequate sanitation, and what they do have — typically pit latrines and lagoons — are responsible for widespread illnesses and a portion of the greenhouse gases that are warming the planet.

UC Merced Professor Rebecca Ryals and a group of colleagues have a solution that not only increases safety, sustainability and jobs, but reduces greenhouse gas emissions and waste-borne illnesses while producing an effective fertilizer for agriculture.

Competitions, showcases, career success stories and more highlight the work of the School of Engineering and its students at UC Merced’s annual celebration of National Engineers Week, Feb. 18 to 21.

E-Week is an opportunity for engineering students to share the work they do with the campus, invite some friendly competition and introduce other students and younger school children to the field. Each day carries a specific theme, from Project Palooza (a showcase for engineering clubs and organizations) to Professional Day (career advice and alumni success stories).

Not spending money on gas, oil changes, and tune-ups and not producing harmful greenhouse gas emissions is enough to sell many people on plug-in electric cars.

But many consumers won’t bite until they’re assured that electric cars can go the distance before needing a charge.

A thin layer of compost applied to grasslands could help fight climate change by capturing carbon from the atmosphere and storing it in the soil, recent research shows.

UC Merced Professor Rebecca Ryals and a team of researchers, ranchers and public agencies will demonstrate this practice for the first time in the East Bay. The project, which began Dec. 3, is funded by a California Department of Food and Agriculture Healthy Soils Demonstration grant.

UC Merced Professor Peggy O’Day hopes to improve water quality in the California Delta by studying local wetlands.

O’Day is leading a new three-year study of Merced County wetlands that drain into the San Joaquin River and eventually the Delta.

Even a little forest management significantly increases water runoff in the Central Sierra Nevada and other semi-arid regions, while drier forests need more extensive treatments, according to a new study published recently in the journal Ecohydrology.

“The result is more runoff to downstream water users,” said UC Merced Professor Martha Conklin , who led the study.
