Sauti ya wakulima, "The voice of the farmers", is a collaborative research project based on cell phone images created by farmers in Tanzania and founded by climate researchers at the Federal Institute of Technology in Zurich.
The farmers gather audiovisual evidence of their daily practices using smartphones and publish their images and voice recordings on the Internet.
The participants, a group of five men and five women, gather every Monday at the agricultural station in Chambezi. They use a laptop computer and a 3G Internet connection to view the images and hear the voice recordings that they posted during the week. They also pass the two available smartphones on to other participants, turning the phones into shared tools for communication.
The farmers at Chambezi not only struggle because of insufficient infrastructure and unreliable markets for their products, but they are also facing the challenges of a changing local climate. Less rain, less ground water and unprecedented threats caused by pests and plant diseases are some of the pressing issues that they have to deal with. They hope that by sharing their knowledge they can overcome the problems.
