Two brothers have brought the plight of some Ethiopian coffee producers to the attention of the world by screening a documentary at a US film festival.
Tadesse Meskela talks to farmers in Southern Ethiopia
Their film, Black Gold, was shown five times to sell-out audiences at the Sundance festival in Utah.
Nick and Marc Francis, of Brighton, set out to show how some farmers lose out in global trading.
Marc Francis, co-director, said: "A lot of people who are being paid an unfair price are struggling to eat."
He said: "We, as taxpayers in the UK, send them emergency food aid to keep them going.
"If they had a fair price for their produce like coffee in the first place we wouldn't need to give them aid."
The Sundance Film Festival, established by actor Robert Redford, finished on 29 January.
During its 25-year history, the festival has showcased successes such as Reservoir Dogs, The Blair Witch Project and The Full Monty.
