Environment

It is said that rainforests are the Earth’s lungs, capturing carbon dioxide from the atmosphere, building it into lush vegetation and releasing oxygen and water back into the air.

When people think of engineering in nature, they tend to think of species such as beavers — the tree-felling, dam-building rodents whose machinations can shape the landscape by creating lakes and changing the path of rivers.

But beavers are far from the only organisms to reshape their environment. A squirrel that inadvertently plants oak trees is also an “ecosystem engineer.” Roughly speaking, any organism whose impact on the environment outlasts its own lifetime is an environmental engineer.

Wildfire seasons are intensifying because of climate change. That means reforestation efforts will increase, making it important for scientists and resource managers to understand how to make sure restorations will thrive in the future.

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.
