摘要

在英联邦和撒哈拉以南发展中国家,正式和非正式城市住区并存的现象在新兴和快速发展的城市中一直是一种常见的现象。以达累斯萨拉姆为例,它是坦桑尼亚最大的、人口密集的商业城市之一;非正式和正式土地权利的二分法在城市周边地区及其城市附近普遍存在,土地从乡村演变为城市。当公共当局不能令人满意地提供公共服务时,就会出现城市住区的二分法,这通常归因于为指导市场力量、城市管理和增长而制定的治理不善和政策。政府采用了不同的策略和方法,至少提供适当的基础设施;然而,大多数方法都不是很成功,并且在实现成本高的情况下交付了预期的结果。为了了解城市类型的空间动态,利用达累斯萨拉姆的人口密度和土地覆被图,了解达累斯萨拉姆城市土地转型的发展特征和建成区的变化检测。通过对地图的分析,可以很容易地观察到城市化的快速发展和建成区面积的急剧增长,特别是在1990-2000年间。

Proliferation of Dichotomy Urban Settlements Plight: Land Governance And Sustainable Built Environment In Tanzania
The observation of the juxtaposition of formal and informal urban settlements in the commonwealth and sub-Saharan developing countries is been trending as a common mundane phenomenon in emerging and fast-growing cities. In Dar es Salaam for example, one of the largest, high-density, and populous businesses cities in Tanzania; dichotomy of informal and formal land rights is ubiquitous in peri-urban areas and its urban vicinities where land evolves from village to urban. The dichotomy of urban settlements occurs when the public authorities do not satisfactorily provide public services which are customarily attributed to poor governance and policies formulated to guide market forces, urban management, and growth. Different strategies and approaches have been applied by the government for at least providing proper infrastructure; however, most of the approaches are not well successful and deliver the expected results following high cost of implementation. To understand the spatial dynamics of urban typology, population density and land cover maps of Dar es Salaam were used to comprehend the developmental characteristics of Dar es Salaam urban land transformation and change detection of built-up area. According to the analysis of the maps, rapid urbanization and dramatical growth in built-up area especially between 1990-2000 years were easily observed.
