ABSTRACT

Sub-Saharan Africa is rapidly urbanising. This urbanisation may contribute to socio-economic development as more people participate in the urban economy. Nevertheless, rapid urbanisation is not always sustainable. Primary cities often grow fast, leaving secondary towns lagging behind with weaker economies. Viable strategies for sustainable urbanisation may therefore also need to focus on developing secondary towns. Nevertheless, very few studies, hitherto, have assessed the (relative) importance of secondary towns in urbanisation process in Sub-Saharan Africa. We aim to address this gap by studying the patterns and explanatory factors of urban population growth in Uganda. Based on a longitudinal analysis of population rank-size distribution, we show that the population distribution gap between secondary towns and the primary city is widening. Nevertheless, statistical analyses further indicate that secondary towns with above 50 000 inhabitants have the highest population growth rates. This indicates that future investments should aim at upgrading socio-economic infrastructures in secondary towns.

撒哈拉以南非洲城市化的空间格局:以乌干达为例

摘要

撒哈拉以南非洲正在迅速城市化。随着更多人参与城市经济,这种城市化可能有助于社会经济发展。然而,快速城市化并不总是可持续的。一线城市往往发展迅速,而二线城市落后于经济疲软。因此,可持续城市化的可行战略可能还需要侧重于发展二线城镇。然而,迄今为止,很少有研究评估二级城镇在撒哈拉以南非洲城市化进程中的(相对)重要性。我们旨在通过研究乌干达城市人口增长的模式和解释因素来解决这一差距。基于对人口等级规模分布的纵向分析,我们发现二线城镇与一线城市之间的人口分布差距正在扩大。然而,统计分析进一步显示,5万人口以上的二线城镇人口增长率最高。这表明未来的投资应着眼于升级二线城镇的社会经济基础设施。
