Brummer: Ag must shift to multi-crop systems

Plant breeders can help America re-orient our dominant system of single-crop agriculture toward a multi-crop landscape that is less costly to farmers, better for the environment, helps slow climate change and still yields a profit. But, those efforts are just one part of a complex system that also will require the buy-in of farmers themselves, supported by political will, new agricultural policies and the cooperation of scientists, seed companies, machinery and fertilizer manufacturers, insurance providers, banks and environmental groups.

Could Vines Be the Answer to Speeding Urban Cooling, Water Reduction in the West?

Perhaps trees aren’t the only green solution when it comes to cooling urban spaces and reducing energy costs. Honeysuckle, Virginia creeper, pink trumpet and other vines could be a fast-growing substitute in climate-smart cities of the future.

Researchers from UC Davis are leading a nearly $880,000 federal grant to study how vines may provide cooling and shade in Western states in less time than it takes a tree to grow tall.

Coast Redwood and Sequoia Genome Sequences Completed

Scientists have completed the sequences for the coast redwood and giant sequoia genomes. The research, officially published this week in the journal G3: Genes, Genomes, Genetics, helps to better explain the genetic basis for these species’ ability to adapt to their changing environments. The research indicates that the coast redwood genome evolved from a single ancestral species.

Almond Orchard Recycling a Climate-Smart Strategy

Recycling trees onsite can sequester carbon, save water and increase crop yields, making it a climate-smart practice for California’s irrigated almond orchards. Professor Amelie Gaudin, Plant Sciences, UC Davis, worked with postdocs, grad students, and Cooperative Extension colleagues.

Wildfire Perceptions Largely Positive After Hiking in a Burned Landscape

When hikers returned to UC Davis Stebbins Cold Canyon Reserve in 2016, a year after the Wragg wildfire, many expected to see a devastated landscape. They did, but many were also energized about the new changes they saw. Allie Weill, then a graduate student with Professor Andrew Latimer, Plant Sciences, published a paper on this.

Plant Adaptation and California’s Changing Environment

Gail Taylor, professor and department chair, spoke to a packed meeting at UC Center Sacramento on “Plant Adaptation to Climate Change in California,” focusing on potential climate change impacts on agriculture. The center educates future policy-makers and leaders in the craft of politics and policy-making.

Becoming Arizona: Sacramento’s Urban Heat Island Divide

Urban heat islands are areas with few trees, little shade and an environment that releases heat into the air. Trees make cities more livable as temperatures rise with climate change. Heat islands can coincide with impoverished areas and human health problems. Mary Cadenasso, Plant Sciences professor, researches heat islands.

Why is One-Third of Our Food Wasted Worldwide?

Nearly one-third of all the global food production is never eaten. We waste 30 million tons of food in the U.S. and 1.3 billion tons worldwide every year. This has huge economic, environmental and social costs. UC Davis faculty Ned Spang (Food Science and Technology) and Beth Mitcham (Plant Sciences) address the many issues that lead to food waste.
