MISSION: Strengthen Food and Nutrition Security

SANGO-Kenya strengthens food and nutrition security by providing training in sustainable agriculture, nutrition, and livelihoods. We primarily focus on women smallholder farmers, who comprise 70% of the smallholder farmers in sub-Saharan Africa. Through these activities, we are empowering the women, equipping them with the knowledge and tools necessary to improve their lives and the lives of their children.

Empowering Women

SANGO-Kenya empowers the women farmers through increased knowledge and skills. This year, we expanded beyond agriculture and nutrition and added training in saving and loaning concepts as well as marketing, to increase the money they make from selling surplus crops. We will continue to add more programs that will strengthen the women’s ability to improve their food, nutrition, and economic security.


SANGO-Kenya is committed to ensuring the sustainability of the land and the program. We promote organic farming methods such as compost manure and natural pesticides. Our staff and trainers are from the communities where we work. Further, by using the trainer of trainers model and developing informed Lead Farmers, we are building a knowledge base in the community to expand and help ensure the lasting impact of the program


From the beginning, SANGO-Kenya has worked closely with the villages where we work to ensure that our programs are addressing their needs. As we grow, we are expanding our networks in the communities, closely collaborating with local officials and leaders, the Ministries of Health and Agriculture, and other community-based organizations.

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 insecure. Seme sub-county is located in Kisumu County along the eastern shores of Lake Victoria in western Kenya. It is a challenging agricultural environment, characterized by sandy soils and a semi-arid climate, which is made even more difficult by climate change.
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; program participants realized increased crop yields, consumption of more nutritious vegetables, and additional income from selling surplus harvests.
The program has grown every year; there are currently more than 250 participants in four villages, with more than 1200 women, children, and other household members benefiting from our programs.
