El artículo, "Asociaciones entre los cambios en los comportamientos de adquisición de alimentos, la ingesta dietética y el peso corporal durante la pandemia de COVID-19 entre los padres de bajos ingresos en California" se publicó recientemente en la revista Nutrients.
Los padres de bajos ingresos en California informaron cambios en los comportamientos de adquisición de alimentos/comidas, la ingesta dietética y el peso corporal desde antes hasta durante la pandemia a través de una encuesta en línea realizada de abril a agosto de 2021. El estudio encontró que la disminución de las compras en el supermercado o en el mercado de agricultores se asoció con una disminución de la ingesta de frutas y verduras y un mayor consumo de bocadillos poco saludables.
La comida en línea y los pedidos de comidas se asociaron con una mayor ingesta de dulces, bocadillos salados, comida rápida y aumentos de peso. Los aumentos en la preparación de comidas saludables en el hogar se asociaron con mejores resultados nutricionales. Esta investigación sugiere la necesidad de intervenciones que apoyen la cocina casera saludable y aborden los efectos negativos de la compra de alimentos y comidas en línea para ayudar a mitigar las disparidades de salud después de la pandemia y prepararse para futuras emergencias similares.
El estudio fue dirigido por las investigadoras del Instituto de Políticas de Nutrición, Gail Woodward-Lopez, Erin Esaryk, Suzanne Rauzon, Sridharshi C. Hewawitharana, con Hannah R. Thompson de la Escuela de Salud Pública de la Universidad de California, Berkeley, y las coautoras del Departamento de Salud Pública de California, Ingrid Cordon y Lauren Whetstone.

Land use change in agricultural frontiers can have far-reaching social and environmental implications, such as habitat loss, water contamination, or worker demographic shifts — particularly when it involves the rapid expansion of a new industry such as cannabis production. A recent study published in Landscape and Urban Planning offers an interdisciplinary perspective on the drivers of cannabis production in rural areas, using interviews with farmers and spatial modeling to uncover key factors.
Led by researchers from UC Berkeley's Department of Environmental Science, Policy, and Management (ESPM) and the Cannabis Research Center, the article “Where money grows on trees: a socio-ecological assessment of land use change in an agricultural frontier” provides a social-ecological systems approach for assessing drivers of cannabis production in Southern Oregon, using interviews with farmers and spatial modeling to uncover key factors.
"Unlike other crops, we have less understanding of where and how cannabis is grown, making it an important area of ongoing research," said Van Butsic, a professor of cooperative extension in ESPM and the senior author of the study.
The researchers interviewed 14 cannabis farmers to identify major themes around their relationships with land use, and used those themes to generate predictors for models of land use change. Most of the interview-derived drivers were significantly associated with cannabis distribution and development, including parcel size, human footprint, distance to the nearest cannabis farm, the density of local cannabis production, clearable land cover, farm zoning, elevation, roughness, and distance to rivers. The interview data also provided insights into the relationship of cannabis with social and environmental dynamics.
“We gained many insights from the interview data,” said lead author and ESPM postdoctoral scholar Phoebe Parker-Shames. “For example, we knew from previous research that cannabis development tends to be clustered, but we understand a little better now that this is related to the ways in which cannabis farmers rely on each other to share knowledge, labor, and navigate uncertainty during difficult policy changes.”
One of the major themes that emerged from the interview data was the environmental stewardship values of the farmers. “There is a large untapped potential for education and management outreach to target farmers who got into this industry in part because of their ability to connect with the land,” Parker-Shames said. “The farmers we spoke to had a genuine desire to learn best practices in an industry without a lot of formal standards for production. I'm grateful that they were willing to share their experiences and insights with us.”
Additional Berkeley co-authors include ESPM professor Justin Brashares and alumni Hekia Bodwitch (PhD '17 ESPM). The study's findings provide valuable insights into the drivers of cannabis production and the environmental stewardship values of cannabis farmers, which can inform environmental policy, regulation, and best practices for sustainable cannabis production.

Chemical ecologist and conservation biologist Leslie Saul-Gershenz of UC Davis and Norman Gershenz, conservation biologist and CEO of SaveNature.Org, will speak on “Is Insect Biodiversity, Biomass and Abundance Declining? What Can Be Done If It Is?” at a public talk on Monday night, March 2, at the Hillside Club's Fireside Lecture Series, Berkeley.
The husband-wife team of environmental scientists will address the audience at 7:30 p.m. The Bay Area venue is in north Berkeley at 2286 Cedar St., between Spruce and Arch streets. (See directions)
They will discuss what factors are affecting native bees and insect populations in California and around the world; review some of the latest body of literature on insect declines; and relate how people can participate to make a positive difference.
Also as part of the Fireside Lecture Series, Kathy Kramer, founder and coordinator of the “Bringing Back the Natives Garden Tour” will discuss “Garden as If Life Depends on It: How Bringing Back the Natives Can Help You Do So” at 7:30 p.m., Monday, April 6.
The events are free and open to the public, but a $10 donation per talk is requested to benefit the speaker fund.
Leslie, who received her doctorate in entomology from UC Davis, is associate director of research, Wild Energy Initiative, John Muir Institute of the Environment, and on March 1, will join the research team at the USDA-ARS Invasive Species and Pollinator Health Research Unit, Davis. She will continue collaborating with the John Muir Institute.
Norm and Leslie co-founded SaveNature.Org, an international conservation program, to "protect terrestrial and aquatic ecosystems worldwide and to inspire stewardship in the public through hands-on education programs." Norm serves as the chief executive officer and director of the Insect Discovery Lab (IDL). (See article on the duo.)
SaveNature.Org conducts nearly 800 hands-on conservation education programs in schools throughout the Greater Bay Area, and reaches more than 38,500 children annually with its IDL. Their work has been highlighted in National Geographic, Time magazine, and ABC's World News Tonight. Robert Pringle's recent article, Upgrading Protected Areas to Conserve Wild Biodiversity, in the journal Nature, details the organization's collaborative work to increase the size of protected areas.
The Hillside Club is a neighborhood social club established in 1898 to promote good design practices in the Berkeley hills; today it is a community-based membership organization supporting the arts and culture.

"Black Friday" means different things to each of us, but when I think of "Black Friday," I think of black bumble bees nectaring on blackberry blossoms in Berkeley.
Bumble bees on blackberry blossoms in Berkeley. Talk about alliteration!
Specifically, I think of the yellow-faced bumble bee, Bombus vosnesenskii, the bee I photographed on a Friday last spring in Berkeley.
Bombus vosnesenskii is among the bees featured in the University of California-authored book, California Bees and Blooms: A Guide for Gardeners and Naturalists, (Heyday Press). It's the work of entomologists Gordon Frankie of UC Berkeley and Robbin Thorp of UC Davis, entomologist/photographer Rollin Coville and plant scientist Barbara Ertter of UC Berkeley. Thorp, a UC Davis distinguished emeritus professor, also co-authoredBumble Bees of North America: An Identification Guide (Princeton University).
Bumble bees are in trouble. Many populations are declining, threatened or endangered. Take the case of critically endangered--or maybe extinct--Franklin's bumble bee (Bombus franklini), which has probably the most restricted or narrowest range of any bumble bee in the world, according to Thorp, who has been monitoring its population--or trying to--since the 1990s. Its habitat is--or was--a small area of southern Oregon (Douglas, Jackson and Josephine counties) and northern California (Siskiyou and Trinity counties). It frequents California poppies, lupines, vetch, wild roses, blackberries, clover, sweet peas, horsemint and mountain penny royal during its flight season, from mid-May through September.
Thorp hasn't seen it for 12 years. He sighted a total of 94 Bombus franklini in 1998; 20 in 1999; 9 in 2000 and only 1 in 2001. Sightings increased slightly to 20 in 2002, but dropped to 3 in 2003. Thorp saw none in 2004 and 2005; one in 2006; and none since. (See his photo of Franklin's bumble bee.)
In a UC Davis interview in July 2010, Thorp told us: “People often ask the value of Franklin's bumble bee. In terms of a direct contribution to the grand scale of human economies, perhaps not much, but no one has measured its contribution in those terms. However, in the grand scheme of our planet and its environmental values, I would say it is priceless."
"Loss of a species, especially a pollinator, diminishes our global environment,” Thorp said. “Bumble bees provide an important ecological service--pollination. This service is critical to reproduction of a huge diversity of plants that in turn provide shelter, food (seeds, fruits) to diverse wildlife. The potential cascade of effects from the removal of even one localized pollinator may affect us directly and indirectly.”
Many factors, including loss of habitat, are involved. Pesticides must share some of the blame. Interesting that researchers at Worchester (Mass.) Polytechnic Institute recently found that bumble bee exposure to neonicotinoids may be contributing to their decline across America. Even small doses, the researchers discovered, reduce the survival of queen and male bees, which are critical to the survival of wild population. (See Worchester Polytechnic Institute news story.)
Bottom line: if bumble bees disappeared, it would not only be a Black Friday, but a Black Monday, Tuesday, Wednesday, Thursday, Saturday and Sunday.
