Tanzania Tree Specialist (Fixed-term)

One Acre Fund is a nonprofit organization that supplies smallholder farmers in Sub-Saharan Africa with the farm inputs, financing, training, and market access they need to grow more food and earn more income. Operating across nine countries including Kenya, Rwanda, Nigeria, Tanzania, Malawi, Zambia, Uganda, Burundi, Ethiopia, and the Democratic Republic of Congo, the organization works with millions of farming families who rely on small, rain-fed plots of land as their primary source of livelihood. By delivering quality seeds, fertilizer, and agricultural services directly to rural farmers, One Acre Fund reports helping clients achieve approximately 45% more farm income on the same land area. One Acre Fund's sustainability and climate mission is embedded throughout its programs. The organization focuses on climate adaptation and mitigation strategies, including agroforestry and tree-planting initiatives, financing and insurance products to help farmers weather climate-related shocks, and innovation in climate-resilient agricultural practices. These efforts are designed to strengthen the long-term resilience of smallholder farmers who are among the most vulnerable to the effects of climate change, while also contributing to carbon sequestration and reduced agricultural emissions across the continent. What distinguishes One Acre Fund is its last-mile delivery model, which brings bundled services directly to farmers in remote rural areas, combined with a rigorous impact measurement methodology including social return on investment analysis. The organization also prioritizes gender-smart agriculture, with women comprising more than 50% of its client base, and maintains a strong commitment to evidence-based programming and transparent reporting on outcomes.

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.
