Tanzanian Beans: A number of different legumes are grown in Tanzania, but the common bean that most farmers plant is grown primarily in the Northern Region, Southern Highlands, and Western Zone. PABRA has bred more than 450 bean varieties since 1996 to make them more resistant to climate change, and to contain more iron and zinc for better nutritional health. They are also bred for farmer preference: different farmers have preferences for colours, shapes, and cooking times.

The Pan-African Bean Research Alliance (PABRA): Works to develop improved, climate-smart and nutritionally dense bean seeds to help farmers increase their yields. Works at every level of the value chain, from seed research, to education and information dissemination, to linking farmers with markets. Funded by a multitude of governments and organizations, including the Government of Canada, the IDRC, USAID, and UKaid.

The International Development Research Centre (IDRC): A Canadian Crown corporation based in Ottawa, Canada that funds research in developing countries. Currently funding a project with Farm Radio International called Scaling Up, which aims to disseminate information about improved bean seeds and agronomic practices.

Farm Radio International: A Canadian-based, not-for-profit organization that works with about 600 radio broadcasters in 38 African countries. Its broadcasters have programming to teach farmers about better agronomic practices, and answer listener-driven questions to help farmers be more productive. In Tanzania, Farm Radio is currently involved in a project with the IDRC called Scaling Up.

Joanne Koola: A widow growing PABRA beans who has been able to update her house several times thanks to a higher income from increased crop yields.

Elisante Sandy: A farmer living outside Arusha who works as a pastor to supplement his farming income. He does not use improved seeds, and the drought in Tanzania has killed many of his crops.

Mama Musa: A farmer near Arusha who does not grow improved beans. She works in the field all day to provide food for her family.

Grace Amanzi: A widow growing PABRA beans who is able to cover the cost of education for her three children. She is currently farming her field in a caretaker capacity until her son comes of age and takes over.
