Almond Orchard Recycling a Climate-Smart Strategy

April 01, 2020
The Practice Can Create Healthier Soils, Save Water and Yield More Almonds

Recycling trees onsite can sequester carbon, save water and increase crop yields, making it a climate-smart practice for California’s irrigated almond orchards, finds a study from the University of California, Davis.

Whole orchard recycling is when old orchard trees are ground, chipped and turned back into the soil before new almond trees are planted.

Wildfire Perceptions Largely Positive After Hiking in a Burned Landscape

Post-Fire Surveys at Stebbins Cold Canyon Reserve Describe ‘Awe-Inspiring’ Experience

 

When hikers returned to UC Davis Stebbins Cold Canyon Reserve in 2016, a year after a wildfire swept through its expanse of oak trees and chaparral in Northern California, half of them expected to see a devastated landscape. But pre- and post-hike surveys conducted by the University of California, Davis, reveal that roughly a third returned energized, awed and excited about the changes they saw.

Concrete Solutions That Lower Both Emissions and Air Pollution

Air Quality and Climate Change Intertwine in Unexpected Ways. A Concrete Example.

 

Sometimes, fixing one problem can create another.

Concrete production contributes 8 percent of global greenhouse gases, and demand continues to rise as populations and incomes grow. Yet some commonly discussed strategies to reduce the sector’s global GHG emissions could, under some scenarios, increase local air pollution and related health damages, according to a study from the University of California, Davis.

Natural Habitat Around Farms a Win for Strawberry Growers, Birds and Consumers

March 11, 2020
Removing Natural Habitat Can Increase Growers’ Costs Up to 76% With No Detectable Effect on Food Safety

Conserving natural habitat around strawberry fields can help protect growers’ yields, their bottom line and the environment with no detectable threat to food safety, indicates a study led by the University of California, Davis.

Global Science Team on Red Alert as Arctic Lands Grow Greener

January 31, 2020

Scientists are adopting new research techniques to tackle the most visible impact of climate change — the so-called greening of Arctic regions.

A paper published today in the journal Nature Climate Change describes how the latest drone and satellite technology is helping an international team of researchers better understand how the vast, treeless region called the tundra is becoming greener.

Outlook for the Polar Regions in a 2 Degrees Warmer World

International Team Assesses Widespread Effects of Polar Warming

With 2019 on pace as one of the warmest years on record, a major new study from the University of California, Davis, reveals how rapidly the Arctic is warming and examines global consequences of continued polar warming. 

The study, published today in the journal Science Advances reports that the Arctic has warmed by 0.75 C in the last decade alone. By comparison, the Earth as a whole has warmed by nearly the same amount, 0.8 C, over the past 137 years.

Calculating the Costs of Ecological Disruption from Climate Change

November 26, 2019

What are the costs if climate change increases the risk of extinction of plants and animals? What value can be placed on reducing the risk of extinction of the white rhinoceros or American pika? And do people consider these things valuable even if they will never see a white rhinoceros or a pika in person?

That value — the “existence value”— is one of the ecological costs being calculated by researchers at UC Davis and Fordham University in order to improve the models currently used to calculate climate change damages, what’s known as the social cost of carbon.

The Survivors: Sugar Pine Trees and the Future Forest

Planting Genetic Resilience Into Forests in the Face of Climate Change

California’s drought and bark-beetle infestation killed more than 129 million trees between 2012 and 2016 in the Sierra Nevada. But amid the devastation stood some survivors.

Becoming Arizona: Sacramento’s Urban Heat Island Divide

Beyond Beautification, Trees Are a Health and Climate Justice Solution

A tree sits in the middle of a big empty lot in South Sacramento. It is huge and leafy, its arms open wide, an arc of green swooping across a hot summer sky. Fenced off in this abandoned car lot, the tree is a bold sign of life in an otherwise barren expanse of dirt and busted concrete. It’s a wonder that it’s still here.

This old lot looms large for Victoria Vasquez. Her dad used to live a half mile from this spot.
