Jacobs Coffee’s sustainability programme, the Wunderbar Project, began in 2023 to support coffee growers in Tanzania’s Kagera region, focusing on better agricultural methods, financial management and new income streams beyond coffee.

The initiative provides training and practical assistance aimed at strengthening farm productivity, helping households secure longer‑term sources of income and encouraging community‑wide entrepreneurship.

Jacobs positions the project as part of its ESG strategy, emphasizing that sustainability starts with people and that farmer‑led transformation is central to lasting impact.

Project accounts cite several farmer stories: Jafari has turned his farm into a community hub with a football‑viewing space; Helena leads a women’s network for shared economic activities; Aderina added dairy farming to improve household food security.

Other participants, such as Johanes, have used coffee earnings to start new businesses, while Balagomwa preserves agricultural knowledge through storytelling and song, illustrating broader community benefits.

Jacobs notes that the project aligns with growing global focus on sustainable supply chains, aiming to reduce farmers’ reliance on a single crop and improve resilience to market or climate shocks.

Independent verification of the programme’s scale and impact, such as changes in household income or productivity, has not yet been published, leaving the full extent of benefits unclear.
