Land Pattern of Highly Urbanizing Cities: Change in Built-up Area, Population Density and Spatial Development of the Sprawling Dar es Salaam City

Abstract

Dar es Salaam is one of the most diverse cities in Tanzania in terms of its physical, social, economic, environmental and spatial features. This diversity has contributed to differences in built-up area, population density, as well as the pace of spatial development across different parts of the city. This study aims to examine the relationship between physical built-up area changes in Dar es Salaam, population density change and spatial development using remote sensing images and census data. The study finds that the city population has grown tremendously, with peri-urban wards in particular having experienced positive growth. Dar es Salam’s built-up area change and urban sprawl emerging at the city’s edges distinctly follows the pattern of demographic change. This is accompanied by substantial compact growth in the inner parts of the city. A number of factors such as transport, residential development, migration, high natural growth rates, public policies and land speculation are found to have contributed to these changes. Overall, the study aims to aid planning authorities in effectively responding to the rapid spatial development taking place in the city, for which a holistic approach that combines an understanding of physical and demographic changes is needed. By investigating the changing patterns in land use within this highly urbanizing city, it aims to generate insights into urban development control machineries and identify their underlying dynamics.

The Development Characteristics of Makassar City in Past and Present

“…In the era of the "Orde Baru" (New Order), the population of Makassar City continued to increase sharply due to increasing urbanization, driving the expansion of the city towards the mainland east and south of Makassar City. This confirms several previous studies that urbanization has a significant effect on spatial changes and urban growth (Ashik, Mim et al, 2020;Brettell, 2000;Msuya, Moshi et al, 2021;Surya, Salim et al, 2021;Yılmaz and Terzi, 2020).…”

Analysis of the Role of Community Actors towards Self-Employment Support for Higher Education Graduates in Tanzania

“…In Dodoma the study was conducted in Dodoma city council, Bahi, Kongwa, Kondoa Town and Kondoa District councils. Dodoma and Dar es Salaam regions are characterized by fast-growing formal and informal sectors attracting self-employment business opportunities (Msuya, Moshi & Levira, 2020). The presence of central government headquarters and functions in these regions attracts a high influx of graduate youths seeking employment opportunities in fast growing sectors in the urban and sub-urban areas of the regions (Danish Trade Union Development Agency, 2022).…”

Evaluation of a participatory approach to stratifying neighbourhoods across the Tanzanian city of Dar es Salaam in terms of income by comparing with latent profile analysis of deprivation based on national census data

“…During the colonial era, the city was planned in a way that segregated people by race and income, with affluent neighbourhoods located near the city centre and along the Indian Ocean (Europeans and Indians) and the less affluent near and around the city centre (black Africans, referred to in that era as natives) (Brennan & Burton, 2007). The evident pattern in the city demonstrates that a significant portion of its development has unfolded through informal processes [5]. Informal settlements tend to be situated either within formal areas or near them, aligning with the contextual reality of the city’s historical evolution.…”
