Namibia traffic taming
Over at BBC Radio 4, in a new series, The Fall and Rise of the Bicycle, Mark Stephen discusses the importance of the bicycle as a global barometer of social, economic and environmental change.
Namibia's scattered population faces a huge struggle against poverty and AIDS. A bicycle can provide great freedom - access to healthcare, education and work - that sheer distance often renders impossible. Taking a trip across this vast country, Mark sees for himself the impact that owning a bicycle can have on the lives of Africa's rural poor.
