Jacqueline Gauthier J-1 Programs, Creative & Administration
Jacqueline has a Masters of Science in Environmental Science, including a thesis project on modeling the chemistry of phosphates in agricultural soils. Her role working as an Environmental Consultant for four years led her to travel to closed mine sites across Canada to assess the soil and water quality. After moving to the Bay Area in 2016 from Guelph, Ontario she had a sabbatical while waiting for a green card petition to be granted; during this time Jacqueline first connected with MESA to volunteer, lending her administrative and graphic design skills. Jacqueline is an avid cyclist and can be found riding the roads and trails in the Berkeley/Oakland hills and beyond.

Emily Kuhn Communications & Programs
Em joins the MESA team freshly invigorated by an agroecology exchange as a Fulbright researcher in Ecuador. She spent the past year working with Kichwa Indigenous communities to record and reinforce the transfer of intergenerational knowledge within the chakra (ancestral food forest). Raised by chefs, Em’s passion for storytelling and food systems are rooted in an upbringing that centered the sacredness of food. While earning a BA in Environmental Sociology and Spanish from Pitzer College, Em deepened her exploration of family migration stories and foodways through the practice of recording oral histories. Inspired to create more spaces for meaningful storytelling, she co-founded The Outback News, a multimedia platform for Pitzer student expression.
In 2020, Em began her hands-on training at permaculture farms, completing her official permaculture certification in 2022. Using what she learned, Em collaborated with the Robert Redford Conservancy to redesign and execute an overhaul of the neglected Pitzer Student Garden. For her senior thesis, she proposed an intercollegiate Agroecology Curriculum. Em hopes that their work at MESA will continue enlivening the global paradigm shift toward socially and ecologically just food systems.

Growing up in the Central Valley of California, she witnessed the negative effects of unsustainable agricultural practices near almond orchards. This has motivated her to pursue her passions for science and education, aiming to address the challenges in our unsustainable agricultural food system.

Claire Hambrick Partnerships & Outreach
Claire Hambrick is passionate about promoting climate action and building community through regenerative farming practices and systems thinking approaches. These interests first sparked on a biodynamic farm in Hawaii where she lived and worked, studying the fundamentals of soil science, composting systems, and impacts of the industrial food system on communities in Hawaii. From there, Claire travelled to Nicaragua to learn from folks at the Asociación de Trabajadores del Campo (rural workers association) and work on a women-owned and operated, agroecological coffee farm. These experiences informed her interest in global food systems and she is proud to be working on promoting global exchanges at MESA!
Claire earned her Bachelor’s of Science in Conservation Resource Studies with a concentration in Community Nutrition and Agricultural Food Systems at UC Berkeley. Since then, Claire has earned a certification in Global Agroecology and finalized her Honors Thesis on the impacts of California’s Agriculture and Food Policy on Urban and Rural Communities.

Waheed Khawrin, Secretary
Waheed’s personal statement: I have 3+ years’ experience of working with non-profits. I have worked with two non-profit organizations: ANHDO (Afghanistan National Horticulture Development Organization) and CoAR
(Coordination of Afghans Relief) in Afghanistan. In my work with ANHDO I assisted in program
coordination and carried out community development-related project activities which involved agriculture extension and working closely with cooperatives. I have worked with CoAR as member of an educational training team which involved supporting agriculture schools in rural areas. I joined MESA in 2018 as an agriculture Steward and hosted by The Natural Grocery Company (NGC) in El Cerrito. The experience at NGC not only helped me to learn more about sustainable agriculture practices that farmers are using to provide healthy food to the communities while preserving the natural environment but, also helped expand my network with organic agriculture farms which were the primary and preferred purchasing source for the NGC. MESA’s stewardship and NGC experience provided me a better understanding of supply chain in organic agriculture sector.
My knowledge, experience and involvement with non-profits particularly MESA throughout the years
will be beneficial to support MESA’s mission.
Samuel Kangethe, Director
In Samuel’s words: “As a child of peasant farmers I was directly involved in gardening activities since my early childhood. My parents struggled to feed us and barely met the family basic needs due to meager income they got working as laborers in the neighboring large scale export coffee farms in Thika township Kenya. Things were not different in the other homes and there was rampant poverty in our community despite the hardworking nature of our people. This childhood experience prompted me to pursue a training in sustainable agriculture and after my graduation from Manor House Agriculture college, Kitale Kenya in 2001. I have never looked back and been a crusader of agroecology and sustainable food systems and social injustice in our local communities. I have been involved in grassroots community food sovereignty activities, social and food injustice and I have networks with Agroecology farmers and changemakers across the world, more so in Africa and the United States Of America. In 2016 MESA sponsored me to attend a 8 month stewardship at Ecology Action- Golden Rule Research farm Willits CA. I had an in-depth and hands-on experience on Grow Biointensive agriculture which is an organic agricultural system that focuses on achieving maximum yields from a minimum area of land, while simultaneously increasing biodiversity and sustaining the fertility of the soil. In 2020-2021 I joined the MESA NLP program. I acquired skills on organic produce sales, marketing, distribution, purchasing and advanced training in sustainable supply chain management. I had an opportunity to be enrolled in an introductory course on agroecology, urban gardening and other development skills. MESA’s AFFP course also covers understanding the intersections of environmental justice, food sovereignty. Currently I am the founder and working with CESBA-KENYA a Community Based Organization which we work with local small holder farmers goal is to address Kajiado and Nairobi county community food insecurity issues, rampant malnutrition among young children, brought about by poor farming practices, climate change and create more food sufficient and resilient households through economic strengthening strategies and sustainable ecological food raising systems.”
