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.
