In recent years Mali's economy has grown steadily at a rate of more than 5 percent per year, driven by developments in gold mining, cereal harvests, and telecommunications. Mali's landlocked condition, together with its very uneven distribution of both population and economic activities between the arid north and the much richer south, challenge the country's ability to sustain this pace of growth. These two aspects define and challenge Mali's development and the infrastructure agendas. The country's strategic focus on the regional agenda has paid off to date, and critical institutional decisions are bringing many positive developments. More than 80 percent of Mali's segments of the West Africa road corridors are maintained in good or fair condition, giving the principal production areas of the south alternative access to the deep-water ports of Dakar, Adidjan, Takoradi, Tema, and Lome. Air transport security has improved, supported by the refurbishment of local airports, including Bamako airport, and the restructuring of Mali's Civil Aviation Authority to increase its autonomy and guarantee harmonization of air transportation rules across West Africa. Mali has also successfully liberalized its mobile telephone markets, with access approaching 40 percent in 2008. Roaming agreements and cross country competition have kept mobile prices low. Access to electricity in Mali more than doubled in the last decade, helped by the introduction of an apparently successful program for rural electrification (AMADER) that widened access to more than 36,000 rural households.
