African urbanization: an analytic policy guide
分析非洲快速城市化的趋势，指出到2050年城市人口将翻三倍，强调政策选择决定城市化是推动经济发展还是加剧贫困与政治不稳定，对政策制定者和研究者有参考价值。
Africa is rapidly urbanizing: it is the most important structural transformation underway in the region. By 2050, almost regardless of government policies, its urban population will have tripled. But the consequences are critically dependent upon policy choices: successful urbanization requires active and far-sighted government. At its best, urbanization can be the essential motor of economic development, rapidly lifting societies out of mass poverty. At its worst, it results in concentrations of squalor and disaffection which ferment political fragility.
