阿克拉是加纳最大的大都会，由于大量未充分利用的地块，除了市中心的非正式住宅区外，其中心位置的低密度具有独特的特点。在过去的三十年里，大都会已经发展到包括它周围的地区，现在被称为大阿克拉都市区。大规模的扩张主要发生在城市的西部和东部，那里的年增长率超过30%。本文探讨了阿克拉大规模扩张的潜在因素，以及遏制扩张的城市遏制战略。它的结论是，虽然许多因素造成的蔓延，关键是薄弱的公共控制土地和由此产生的不良空间规划。因此，在现有的土地管理制度下，任何城市遏制战略都不太可能成功，因为土地是在传统机构下私人拥有的，而规划仍然是地方政府的公共职能。
Accra, Ghana’s largest metropolis, exhibits unique features in terms of low densities in central locations due to large number of under-used plots, except inner-city informal residential areas. Over the last three decades, the metropolis has grown to encompass it surround district, now referred to as the Greater Accra Metropolitan Area. The massive sprawl has largely occurred in the west and east of the city, where growth rates of over 30% per annum have been recorded. This paper examines factors underlying the massive expansion of Accra, and the urban containment strategy to curtail the sprawl. It concludes that though many factors account for the sprawl, the key is the weak public control over land and the resultant poor spatial planning. As such, any urban containment strategy is unlikely to succeed within the context of the existing land management system where land is held privately under customary institutions while planning remains a public functions for local governments.
