The Vantage Point



Glenda Humiston 

Vice President

UC Agriculture and Natural Resources 


Recent news about historically warm ocean temperatures off the California coast – on the heels of record-breaking heat in many parts of the state in March – illustrate the extremes of a changing climate. The unusual weather and hydrological whiplash this winter, discussed by UC ANR/California Institute for Water Resources climate scientist Daniel Swain on his indispensable livestreams, remind us there is much to learn about climactic phenomena and how we can best adapt to their cascading impacts.


Last week, I was truly inspired by what I heard during the EarthX 2026 Congress of Conferences in Dallas. One of the world’s premier sustainability gatherings, EarthX brings together leaders and innovators to discuss environmental education and policy solutions, share the latest technologies and build productive partnerships. During the Bioeconomy Symposium at EarthX, I was honored to speak alongside Blake Simmons, director of the Biological Systems and Engineering Division at Lawrence Berkeley National Laboratory.


Cross-sector collaborations are the key to growing the bioeconomy, which sustainably uses renewable biological resources to produce food, energy, materials and other goods. We emphasized UC’s role as a driver of bioeconomic activity by advancing the viability of bioplastics, biofuels and a wide array of products made from woody biomass and agricultural waste.


According to a March 2024 USDA report, biobased products contributed $489 billion to the U.S. economy in 2021, a $25 billion increase over 2020, despite the pandemic. In this area of tremendous potential, California has made immense strides in investing in research and infrastructure; removing barriers and providing incentives for bioproduct manufacturing; and creating new tools, markets and supportive innovation ecosystems. I was especially proud to highlight The Plant – a state-of-the-art center that will generate practical solutions for the agri-food sector – as well as UC ANR Innovate, which spearheads our work in ag tech, farm robotics, bioproducts and more.


Our innovation initiatives were among the many aspects of UC ANR highlighted during Ag Day at the Capitol on April 21 (watch video). The annual event, held by the California Department of Food and Agriculture, invites elected officials, staffers and the broader community to learn about a host of organizations supporting California agriculture. I want to extend special thanks to UC President James Milliken, who greeted our 4-H State Ambassadors and the youngsters and volunteers from the Sheldon 4-H club. And, of course, my gratitude goes out to the UC Master Gardeners team, UCCE academics and UC ANR staff who represented us so well – despite a heavy downpour! Extra kudos to Nestor Lopez, assistant director of government and community relations, who expertly organized our contingent.


Nestor and Anne Megaro also put together a fantastic UC ANR Advocacy Day on April 14 at the State Capitol. I was very pleased to join them, along with Executive Director of County Cooperative Extension Janine Woods, UCCE specialist Keith Taylor, UCCE forestry advisor Yana Valachovic, Katie Low of the UC ANR Fire Network and Hanif Houston of UC ANR Innovate, who all did a phenomenal job of talking about our impact. My thanks to Sen. Josh Becker and Assemblymembers Cecilia Aguiar-Curry, Heather Hadwick and Esmeralda Soria, and to staff members at several other legislative offices, for taking the time to hear how UC ANR improves the lives of their constituents. Also, a special note of gratitude to Assemblymember Jacqui Irwin for sponsoring our visit to the Assembly floor.


When it comes to long-term impact on communities and an entire field and vocation, few can match the career of Mary Blackburn, the UCCE nutrition, family and consumer sciences advisor for Alameda County who retired last year. I strongly recommend you read about Dr. B’s extraordinary life and contributions to the health and well-being of so many people. We cannot thank Dr. B enough for her bravery and brilliance in breaking barriers – while building the enduring vitality of entire communities. 


A few more links for your perusal this month… be sure to check out this wonderful feature by UC Berkeley about alumni, such as UCCE advisors Ricky Satomi and Brent Holtz, who are making a difference in rural California. And, as we wrap up Earth Month, get inspired by the stories of Sarah-Mae Nelson, who leads our Climate Stewards course, and Daisy Prado, a certified UC California Naturalist. These women epitomize the mission of our amazing UC Environmental Stewards program – to provide people with the skills and confidence they need to share the care for, as Daisy puts it, “our collective home.”


On UC ANR Giving Day (see below), I hope you’ll support our environmental education programs and the full breadth of our work that benefits people, prosperity and the planet. Thank you!

The Donor Difference

UC ANR Giving Day: Donors make the difference

UC ANR Giving Day is more than a 24-hour campaign – it’s a powerful reminder that meaningful change begins with people like you.


From noon on Thursday, May 14, to noon on Friday, May 15, supporters across California will come together to invest in the work of UC Agriculture and Natural Resources. And at the heart of it all are donors – individuals who believe in the power of science, education and community to create a better future.


With the support of donor generosity, UC ANR programs continue to thrive in communities statewide. Gifts made on UC ANR Giving Day help fund hands-on learning in demonstration gardens, open doors for youth through scholarships, and deliver trusted, science-based information to farmers, families and local leaders. These are real, tangible impacts made possible by people who choose to give.


What began as a single day of support has grown into a tradition of collective impact. Over the past seven years, donors have contributed more than half a million dollars to programs that strengthen California’s food systems, protect natural resources and improve community well-being.


This UC ANR Giving Day, your support becomes part of something bigger. Every gift – no matter the size – adds momentum, expands reach and helps UC ANR continue our work to serve all Californians.


Mark your calendar, share the opportunity and consider the role you can play. When you give, you’re helping drive solutions, empower communities and shape a more resilient California. Join us at give.ucanr.edu and be the difference.

Notes from the Field

Dogs with jobs: Pups go on pest patrol as rodenticides phase out

During the 2026 Vertebrate Pest Conference in Southern California, attendees visited a working farm to watch JJ, a rodent detection dog, at work. The field trip was organized by UC Cooperative Extension human-wildlife interactions advisor Niamh Quinn. By identifying rodent activity before infestations become obvious, dogs can help land managers rely less heavily on toxic measures. “We know that dogs can do amazing things, right? We’ve seen them sniff out cancer and COVID and bombs,” Quinn said. “Dogs have potential.” Read full story.
