About One Acre Fund

Founded in 2006, One Acre Fund equips 5.5 million smallholder farmers to make their farms more productive. Across nine countries that together are home to two-thirds of Africa's farmers, we provide high-quality farm supplies, tree seedlings, accessible credit, modern agronomic training, and a wide range of other agricultural services. On average, this model enables any farmer to increase their income and assets on supported land by more than 35 percent, while permanently improving their resilience. This is all made possible by our team of 9,000+ full-time staff, drawn from diverse backgrounds and professions. To learn more, please see our Why Work Here blog post.

Our Tanzania program, founded in 2013, serves approximately. 150,000 farmers, providing quality farm supplies through a network of agrodealer shops, and a range of different tree species through local nurseries situated close to farmers. Our team in Tanzania is headquartered in Iringa and supported by three smaller offices—Mbeya and Njombe in the southern highlands. To learn more about our work, look at our Tanzania program blog.
