A challenge for researchers and other developers of new technologies in agriculture is to find ways of communicating their results and recommendations. This challenge is particularly acute in regions in which farmers have limited access to education and where illiteracy is widespread, such as in the rural areas of Mali. One approach that shows potential, yet remains largely unused by extension services, is the dissemination of educational video on mobile phones with video and Bluetooth technology, which are widespread in the region.

Lesotho is one of the poorest countries in Southern Africa, and has one of the highest income inequality in the world. Home to about 2 million people, Lesotho is surrounded by South Africa, the second largest and most industrialized economy in Africa. Lesotho generates income mainly by exporting textiles, water, and diamonds, and is a member of the Southern African Customs Union (SACU), the Southern African Development Community (SADC), and the Common Monetary Area (CMA). The national currency, the loti, is pegged to the South African rand.
