While many parts of the world battle against the rising tide of cars and lorries, for at least 400 million Africans transport problems are of a completely different order. In rural Africa, south of the Sahara desert, there are few roads, let alone vehicles to drive down them. For some communities the choice is stark: if you want a road you have to build it and maintain it yourself. But roads are not just a matter of convenience, they are essential for basic services such as access to healthcare, employment, education and business opportunities. Earth Report visits Guinea, Senegal, Tanzania and Malawi to find out how communities are helping themselves to develop roads and low cost modes of transport.
