ABSTRACT The connection between city development patterns, housing and service provision is critical as it affects allocation of scarce resources in the cities of Sub Sahara Africa, where the adopted planning models and concepts seem to have minimal success. Through spatial analysis and quantitative research this study explores sequencing of servicing and housing development as it impacts city spatial growth patterns in a context of resource deficiency in Dar es Salaam City. The study finds that despite households’ land ownership being crucial in city spatial expansion process towards residential house ownership, their actual construction and occupation will depend on the accessibility of services. Moreover, it was established that as more services become available, proportionally, number of people settling in new areas increases. Since this process happens equally in planned and unplanned settlements, this study indicates that it is the availability of services and not land allocation that triggers actual development of residential housing. Thus, service provision determines the pace of change in short and medium city spatial patterns. This implies that in the context of public resource deficiency and self-help housing, strategic investments in basic services such as electricity connection, public transport and portable water is the way to influence actual city development pattern rather than providing plots.

评估服务提供对达累斯萨拉姆住宅发展速度和中短期发展模式的影响

摘要 城市发展模式、住房和服务提供之间的联系至关重要，因为它影响了撒哈拉以南非洲城市稀缺资源的分配，在那里采用的规划模型和概念似乎收效甚微。通过空间分析和定量研究，本研究探讨了服务和住房开发的排序，因为它影响了达累斯萨拉姆市资源短缺背景下的城市空间增长模式。研究发现，尽管家庭土地所有权在城市空间扩张向住宅所有权的过程中至关重要，但他们的实际建设和占用将取决于服务的可及性。此外，已经确定，随着更多服务的提供，在新地区定居的人数会按比例增加。由于这一过程在计划和计划外的定居点中同样发生，因此本研究表明，触发住宅的实际开发的是服务的可用性而不是土地分配。因此，服务提供决定了中短城市空间格局的变化速度。这意味着，在公共资源匮乏和住房自助的背景下，对电力连接、公共交通和饮用水等基本服务的战略投资是影响城市实际发展格局的方式，而不是提供地块。服务供给决定了中短城市空间格局的变化速度。这意味着，在公共资源匮乏和住房自助的背景下，对电力连接、公共交通和饮用水等基本服务的战略投资是影响城市实际发展格局的方式，而不是提供地块。服务供给决定了中短城市空间格局的变化速度。这意味着，在公共资源匮乏和住房自助的背景下，对电力连接、公共交通和饮用水等基本服务的战略投资是影响城市实际发展格局的方式，而不是提供地块。
