Amrita Mukherjee
Urban agriculture and small farms advisor
Los Angeles, San Bernardino, Riverside and Orange counties

Amrita Mukherjee joined UC ANR on April 1 as an urban agriculture and small farms advisor serving Los Angeles, San Bernardino, Riverside and Orange counties.

Mukherjee's priority is to understand small farms' practices and needs, and to identify opportunities for improvement and/or collaboration. One challenge that Mukherjee is eager to overcome is getting information to farmers in a timely and organized manner.

“There's so much information out there and it's hard to know who is doing what,” she said. By implementing a communication system, Mukherjee believes that supporting small farms will become more efficient. 

Originally from Bangladesh, Mukherjee grew up in a family of farmers and understands the struggles farmers encounter as laborers and as a business. Her upbringing inspired her to not only pursue a career in agriculture, but to alleviate the hardships that often burden farmers.

Previously, Mukherjee worked for the International Rice Research Institute where she examined flash flood risk-management in her homeland. She also worked for the Horticulture Innovation Lab management team at UC Davis as an assistant specialist in Bangladesh, focused on nutrition impacts of horticultural innovations.  

Mukherjee earned a bachelor's degree in agriculture from Khulna University, a master's degree in biotechnology from Bangladesh Agricultural University, and a master's degree in horticulture, plant biology and post-harvest physiology from Kansas State University.

While she has dedicated the first few months of her role to networking, Mukherjee feels that building rapport with small-scale farmers is an ongoing process that is crucial to her role as an advisor.

When asked what she is most excited about, Mukherjee said that she wants to help farmers grow. Not just their crops, but their business strategy and network. “I don't want to be a supervisor, I want to be a connector,” explained Mukherjee. 

Mukherjee is based out of the UC Cooperative Extension office in San Bernardino County and can be reached at More information. Back to top.
