Tanzania Carbon Credits Supervisor (Fixed-Term)

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, supports more than 100,000 farmers with quality farm supplies, as well as fruit trees. Our team in Tanzania is headquartered in Iringa and supported by three smaller offices—Mbeya and Njombe in the southern highlands, and Moshi in the north where the team is focused on expanding our services to new clients. One Acre Fund works in select areas in the Iringa and Mbeya regions, with a growing presence in the country’s north.
