Mosase named UCCE SoCal urban watershed resilience advisor
Esther Mosase began a new role on Sept. 1, 2023, as a UC Cooperative Extension urban watershed resilience advisor, serving Los Angeles, Orange, Riverside and San Bernardino counties.
Previously, Mosase was a UCCE community education specialist focused on climate-smart agriculture for San Diego and Riverside counties. Her work involved water conservation, soil health and alternative manure management efforts. She also supported farmers in securing funding for climate-smart agricultural practices.
In her new role, Mosase will be responsible for increasing the resilience of urban watersheds to secure water accessibility, availability and quality.
Concerns that are top of mind for Mosase include pollution exacerbated by urban development and tourism, which threatens the quality of available water. With urbanization comes infrastructure, such as roads that are a lot less permeable than grass, contributing to runoff instead of infiltration. Climate change also continues to produce heavy rainfall and, in some cases, flooding. Mosase is interested in understanding how these factors will impact watersheds and the communities that depend on them.
“My job is also working with communities for equity purposes,” said Mosase, noting that community members likely have reliable insight as to how their local watersheds behave, but are also more vulnerable to negative impacts affecting the watershed. “It'll be interesting to hear and learn from these communities because they see a lot more than we do.”
Mosase earned a doctorate in civil and environmental engineering, focused on modeling water availability, risk and resilience, from South Dakota State University. She also holds a master's degree in agricultural engineering from Botswana College of Agriculture and a bachelor's degree in engineering from the University of Botswana.
When asked what she is most excited about in her new role, Mosase said that she looks forward to educating and inspiring the younger generation to get involved.
“I realized that I never really talked to my daughter about my work. But she learned about climate change, and she's so obsessed now,” said Mosase. “Her excitement makes me excited about involving kids and teaching them about water and climate change and its effects while they're young.”
Mosase is based at the UC South Coast Research and Extension Center in Irvine and can be reached at enmosase@ucanr.edu.
Das joins UCCE as regenerative agriculture specialist
Srabani Das joined UC Cooperative Extension on Aug. 29, 2023, as a regenerative agriculture specialist at the UC Merced campus. While Das supports statewide efforts, she is especially excited about working in the surrounding Central Valley.
Das describes regenerative agriculture as “incorporating collaborative practices that make agriculture more sustainable, nourishing people and Mother Earth.” With her background in soil health, Das is helping farmers adopt practices that not only increase crop productivity, but also sequester soil carbon.
“Regenerative ag is not new; it is only now that it is being labeled and communities are realizing that it can be a powerful vehicle for climate mitigation and environmental justice,” she said.
Before joining UC Cooperative Extension, Das worked for the Agricultural Sustainability Institute at UC Davis on the Century Experiment, which focused on tracking the influence of different fertilizer, cover crop and irrigation systems on soil health. Prior to moving to California, she worked for The Ohio State University, collaborating with corn, soybean and pasture farmers and Ohio State Extension.
“I was responsible for assessing the soil's physical and chemical properties, and communicating the impacts of on-farm practices on the soil health of prime agricultural lands that have been cultivated for more than 100 years,” Das said.
Practices such as conventional tilling cause erosion so minimum tillage is preferred. “Other practices like covering the soil, increasing crop diversity, rotating crops, planting perennials are also important to improve soil health,” she added.
For California, Das said an immediate need is developing decision-support tools that will aid farmers with tracking soil-carbon buildup from regenerative agricultural practices. She wants to make those resources equitably accessible for all growers, especially those who are marginalized, women or members of racially or ethnically diverse communities.
Currently, she is partnering with the Compost Climate Action Plan in San Joaquin Valley, led by UC Merced, which aims to advance the science, education and practice of composting. Das co-leads the outreach efforts of the project.
Das earned a bachelor's degree in plant biology and a master's degree in environmental sciences from the Indian Institute of Technology in Mumbai, India. She also earned a doctorate from Cornell University in biological and environmental engineering, studying soil carbon sequestration in marginal lands.
Das can be reached at sradas@ucanr.edu.

Drought focus of Water Resources IMPACT magazine special issue
UC ANR experts address emotional toll of drought
Preparing the American West for prolonged drought is the focus of a double issue of Water Resources IMPACT magazine. The California Water Commission staff are guest editors for this special open-access edition of the magazine, which is published by the American Water Resources Association.
Faith Kearns, academic coordinator of University of California Agriculture and Natural Resources' California Institute for Water Resources, is among the authors delving into how drought impacts people and the environment and how we can better prepare for the inevitable.
The first issue, published on Feb. 14, focuses on water scarcity issues confronting California and the ways these issues affect different sectors.
In “Trauma, Care, and Solidarity: Addressing the Emotional Toll of Chronic Drought,” Kearns highlights the effects of drought on mental health. She points to the spike in suicide hotline calls when wells ran dry in Southeast Asian communities in California's Central Valley.
By listening to Southeast Asian farmers, Ruth Dahlquist-Willard and Michael Yang of UC Cooperative Extension were able to “lighten the load” for them by providing pragmatic support, Kearns writes.
“The scale of some of these highly emotional issues – drought, wildfires, climate change – can make them seem incredibly difficult, if not impossible, to deal with,” Kearns said. “At the same time, they are affecting everyone living in the western U.S. on a daily basis. I wanted to highlight and provide models based on work that people – whether they are researchers, clinical psychologists, or Cooperative Extension advisors – are doing right now to ease the way.”
The authors who contributed to the double issue are a diverse array of Tribal experts, academics, nongovernmental organization thought-leaders, water managers and water policy influencers, each of whom brings their own perspective on the topic of drought. Their expertise and perspectives in climate science, water policy and water management will help inform drought-related decision-making and support policies that better prepare the state to thrive during periods of prolonged water scarcity.
In addition to Kearns, the first issue includes articles contributed by:
- Samantha Stevenson, University of California, Santa Barbara
- Jay Lund, University of California, Davis
- Ron Goode, North Fork Mono Tribe
- Andy Fecko, Placer County Water Agency
- Jeff Mount, Public Policy Institute of California, and Ted Grantham, University of California, Berkeley/UC Cooperative Extension
- Nat Seavy and Karyn Stockdale, National Audubon Society
- Kjia Rivers, Community Water Center
- Cannon Michael, Bowles Farming
- Michelle Reimers, Turlock Irrigation District
The January/February edition of Water Resources IMPACT magazine can be accessed, free of charge, on the American Water Resources Association website at https://www.awra.org under “Publications.”
The second issue, to be published in March, will focus on drought response, considering the options for adaptation. This two-part series complements the Commission's work on strategies to protect communities and fish and wildlife in the event of a long-term drought.
Your water-efficient landscape doesn’t have to be barren
UC climate-ready landscape trials identify low-water yet attractive plants
Good news: roses can be a part of your water-efficient landscape. Lorence Oki, UC Cooperative Extension environmental horticulture specialist in the UC Davis Department of Plant Sciences, identified rose cultivars that remain aesthetically pleasing with little water.
Oki is the principal investigator of the Climate-Ready Landscape Plants project, which may be the largest irrigation trial in the western U.S., and the UC Plant Landscape Irrigation Trials (UCLPIT), the California component of that project. These projects evaluate landscape plants under varying irrigation levels to determine their optimal performance in regions requiring supplemental summer water.
“There are some assumptions that pretty plants use a lot of water, like roses,” Oki said. “Everyone thinks they need a lot of water, but we've found some that don't, and they still look great. A water-efficient landscape doesn't need to look like a Central Valley oak-grassland in the summer. It can look really attractive.”
In 2021, Oki's team at UC Davis identified Lomandra confertifolia ssp. pallida "Pom Pom" Shorty and Rosa "Sprogreatpink" Brick House® Pink as two of the best low-water plants in the trial.
“The useful tip or information that is shared at the end of each trial is the selection and designation of plants as Blue Ribbon winners. These are the plants that looked good with an overall rating of 4 or higher throughout and were on the low (20%) water treatment,” said Natalie Levy, associate specialist for water resources, who manages the project at the UC ANR South Coast Research and Extension Center.
How plants earn a blue ribbon
Each trial year, the selection of new plants is based on research recommendations and donated submissions from the nursery industry. The landscape plants are trialed in full sun or 50% shade cover.
Irrigation treatments are based on the rate of evaporation and plant transpiration (evapotranspiration) measured through a local California Irrigation Management Information System (CIMIS) weather station that provides a reference evapotranspiration (ETo) rate.
Three levels of irrigation are provided to the plants equal to 20%, 50%, and 80% of ETo. The volume of water applied is the same at each irrigation based on soil characteristics, but the interval between applications varies with weather and the treatment. Using this method, irrigations for the 20% treatment are less frequent than the 80% treatment.
“The 20% treatment during the 2022 trial was irrigated an average of once per month while the 80% treatment was irrigated weekly,” explained Levy.
During the deficit irrigation trial, monthly height and width measurements are taken to determine the plant growth index. Monthly qualitative aesthetic ratings on a scale of 1 to 5 are determined for foliage appearance, flowering abundance, pest tolerance, disease resistance, vigor and overall appearance.
A second round of flowering abundance and overall appearance measurements are also taken to capture more of the blooming period. For example, UCLPIT identified in the 2020 trial at South Coast REC that the "Apricot Drift" rose had a mean overall appearance score of 3.5 out of 5, deeming it “acceptable to very nice” and a low water use plant within the Water Use Classification of Landscape Species or WUCOLS guide.
Project expands options for landscape planting
“(WUCOLS) only has 3,500 plants in it. There are guesses that there are close to 10,000 cultivars in urban landscapes in California, if not more,” said Oki. “WUCOLS also didn't have numerical ratings. Instead, you'll see verbal ratings like ‘low water use' or ‘high water use.'”
The UCLPIT project has not only developed numerical recommendations for irrigation, but it has also added new landscape plants that are compliant with California's Model Water Efficient Landscape Ordinance. In fact, UCLPIT's data is one of the few sources that can be used to supplement WUCOLS.
Geographic diversity of trial sites adds to knowledge base
In addition to UC Davis and South Coast REC in Irvine, the trials have expanded beyond California as the Climate-Ready Landscape Plants project and is in progress at Oregon State University, University of Washington, University of Arizona and Utah State University thanks to a USDA/CDFA grant awarded in 2020.
Lloyd Nackley, associate professor of nursery production and greenhouse management at Oregon State University, is the principal investigator of the trial in the Portland metro area, which is entering its third year.
“People know that there are drought tolerant plants, but there are many. We're trying to highlight lesser known or newer varieties. And even though the trial is three years, most gardeners would hope that their garden lasts longer than that,” said Nackley.
One of the observations that Nackley recalls is of the Hibiscus Purple Pillar plant. Unlike the trial at South Coast, the Purple Pillar did not perform well in Oregon in the spring.
“It wasn't until August that we saw the plant bloom and begin to look like what we saw from South Coast in April,” Nackley said.
Ursula Schuch, horticulture professor and principal investigator of the trial taking place at the University of Arizona, was also surprised at the range of performance among different plant types and the effects of irrigation, heat and temperature.
“This research will reassure green industry professionals that they can stretch their water budget to successfully cultivate more plants, watering them according to their needs instead of irrigating every plant according to the highest water-using plants,” said Schuch.
Although research is only conducted in the West, the hope is that there will be trials in other regions of U.S.
Doing so would yield comprehensive information about the plants and their performance in different climates. As extreme weather events persist in the U.S., disease pressure and risks do too. Trials throughout the country would provide location-specific data regarding disease susceptibility.
