For decades now, radio has been a dominant source of information for farmers in much of sub-Saharan Africa. Although the reach of radio varies from country to country, it is estimated that between 80 and 90 percent of households in Africa have access to a functional radio. The liberalization of regulatory environments in a number of countries has further increased the number of independent and community radio stations broadcasting over the airwaves.1 Given the fact that adult literacy rates in sub-Saharan Africa are just over 60 percent and that electricity in many rural communities is non-existent, battery-powered radios are often the most affordable and practical way for rural farmers to access information.
