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.

One Acre Fund runs a pilot program in Zambia’s Central Province. Our Zambia pilot is exploring ways we can help farmers improve harvests on larger plots of land, which are common in the country. Our office in Zambia is located in Kabwe, the capital of the Central Province.
