MISSION: Strengthen Food and Nutrition Security

SANGO-Kenya’s programs help alleviate food and nutrition insecurity by providing in-class training and field support for women smallholder farmers in nutrition and sustainable agricultural practices. Our programs focus on African traditional foods, which are high in nutrients and grow well in the challenging farming environment of Seme sub-County, characterized by sandy soils and a semi-arid climate, made even more difficult due to climate change. Participants in SANGO-Kenya’s programs also realize improved economic security from having to buy fewer vegetables from the markets and by selling their own surpluses.


SANGO-Kenya was founded in 2020 by Director of Programs and Research Constance Gewa, Ph.D. and Executive Director Kit Goldfarb, MPH. SANGO-Kenya grew out of 2017 research in food security conducted by Constance that found that 60% of households in Seme sub-County are food. Seme sub-county is located in Kisumu County along the eastern shores of Lake Victoria in western Kenya.

Constance and Kit returned in 2019 to meet with study participants and community leaders to present the findings of the research and gather feedback. SANGO-Kenya’s programs grew out of the feedback from these meetings.

A pilot program was conducted from January – June 2020 with 19 women smallholder farmers in one village in Seme. Since then, the program has expanded to three villages and includes 130 women farmers, directly impacting more than 600 women, children, and other family members. Our programs, which focus on African traditional and other nutritious foods that grow well in Seme’s environment, are now conducted in both the long rains (March-May) and the short rains (September-October), providing farmers year-round support.  

The 1000 Days
SANGO-Kenya’s programs focus on the first 1,000 days, an approach driven by the recognition that the 1,000 days between a woman’s pregnancy and the first 24 months of her child’s life are critical for all aspects of the child’s health and development. Adhering to that focus, SANGO-Kenya provides nutrition and agriculture training for women who are of reproductive age (15-49) and are pregnant and/or have children, especially children under two years of age.

Our programs are community based. The concepts originated with Constance’s 2017 research in food and nutrition security and are developed with continuous feedback from community members and leaders, including partnerships with the Ministries of Health and Agriculture, local women’s groups, and other community-based organizations.

Empowerment and Sustainability
SANGO-Kenya is committed to sustainability and empowering our participants and staff. All of our staff and trainers are from the area. We include leadership development in our training programs for all of the farmers. Additionally, we use the trainer of trainers model, providing additional training to Lead Farmers, who provide other farmers on-going support during the growing season. We recently included the use of smart phone technology, training local Community Health Volunteers and students to collect data using online forms instead of paper questionnaires.
