“…The tendency of decreasing population densities crosswise several cities is not limited to Ethiopian cities alone; however, it has also been witnessed in other parts of the world. For instance, Arua, Uganda [25] and Fez, Morocco [24] from other African cities, reported low-land use efficiency. Jain and Sharma [59] described, Indian cities have low-density urban development trends.…”

“…Africa is the least urbanized continent with 43 percent of its inhabitants living in the urban regions [2]. Nevertheless, most African cities are challenged by problems related to unplanned and uncontrolled rapid urban growth as informal settlements [4,21,[23][24][25], become a part of the urban ecosystems. Therefore, understanding and comparing the evolution of urbanization, in large and mid-sized cities could provide a reference for urban and ecological planning, and for sustainable development.…”

Urban Expansion in Ethiopia from 1987 to 2017: Characteristics, Spatial Patterns, and Driving Forces

Rapid urban growth in major cities of a country poses challenges for sustainable development. Particularly in Africa, the process of rapid urbanization is little understood and research is mostly limited to single cities. Thus, this study provides a comprehensive comparative analysis of the growth and spatial patterns of urban development in the three major cities of Ethiopia (Addis Ababa, Adama, and Hawassa) from 1987 to 2017. Also, the applicability of diffusion and coalescence theory on the evolution of these cities has been tested. Remote sensing and GIS technologies were combined with spatial metrics and morphological analysis was employed to undertake this study. The result revealed that all the studied cities experienced accelerated growth in the urbanized areas, but the cities with a larger initial urbanized size were associated with lower expansion rates. Differences in extent and direction of expansion in each city were mostly related to physical features, urban master plans, and policies, with an increase in the irregularity and dispersion of urban growth, representing strong evidence of urban sprawl. The spatiotemporal analysis confirmed that the urbanization processes of Addis Ababa and Adama were consistent and Hawassa city diverged from expectations based on diffusion and coalescence theory. In general, large cities with strong economic growth in a country fail to effectively control the scattered nature of urban growth, thus requiring aggressive policy intervention. The approach used in this study permits a deeper exploration of urban development patterns and the identification of priority areas for effective urban planning and management.

“…Due to urban sprawl, the urban landscape (form) is reshaped and urban areas attain attributes which include low density development (which characterises single or small family neighbourhoods which are far from consolidated city centres where the core of urban services exist), and scattered neighbourhoods [36]. Furthermore, urban sprawl contributes to segregated land-use regimes [36,37], and peri-urbanisation, which is the extension of urban areas beyond administrative boundaries into adjoining rural districts such that there is a clash between urban and rural uses of land [36]. However, some scholars, e.g., [38], call for a cautious interpretation of the significance of density as its perception may be cultural rather than absolute.…”

Ghana is urbanising rapidly, and over half of the country’s population have lived in urban areas since 2010. Although research has proliferated to explore Ghana’s urbanisation, there is a dearth of research that holistically explores the wider sustainability implications of urbanisation, offers comparative perspectives in the context of large and smaller urban areas, and provides a perspective of local level urbanisation in the context of resource extraction (mining). This study comparatively assesses two urban areas in Ghana (Kumasi and Obuasi), by conducting a spatio-temporal analysis of land cover change through remote sensing and by analysing demographic change through a synthesis of published population data, in order to highlight the sustainability implications of urbanisation. The results show that urbanisation has been rapid, and has resulted in changes in land cover and demography in Kumasi and Obuasi. The sustainability implications of urbanisation are identified to include limited economic opportunities, socio-spatial segregation, and destruction of natural vegetation. The evidence in this study provides insights into urbanisation in Ghana, and suggests that the positive sustainability impacts of urbanisation may be eroded by how factors such as market forces and land tenure interact at the local level.

“…The most frequent human activities were noted along the surrounding zones directly in vicinity of the Municipality urban centers from Ozu cell to Ediofe. This could be attributed to high population growth rate of Arua Municipality (UBOS as cited in Abudu et al, 2018). As population increases, space and resources become limited and thus, people can be easily driven to earn livelihood from gazzetted places and resources.…”

“…Uganda has been one of the fastest growing population in Africa (Lopes, 2016) and Arua Municipality in Uganda is a fast urbanizing town which has recently experienced a rapid population growth resulting into emergence of many economic activities (Abudu, Azo, & Andogah, 2018). Reports show increasing trends of settlement and encroachment in the protected zones of river Enyau and the wetlands in Arua district to access water and land for economic activities (Atlas, 2016;Kansiime, Muwanga, & Niwagaba, 2013;Abudu et al, 2018) despite the National Environment Regulations, NER (2000) of no human activity within 30 metres from the highest water mark on either sides of the river bank. The guideline also recommends the land owners surrounding the river to undertake conservation measures.…”

This study documented the human activities carried out in the protected zones of river Enyau (within 30 m of river's bank) and their influence on the quality of the river. Human activities in the protected bank of river Enyau and the quality of the river were ascertained during a field survey in March-May, 2019.The diversity of macrozoobenthic invertebrates per site and water pollution levels were determined using Shannon-Weiner (Hʹ) and Biological Monitoring Working Party (BMWP) indices respectively. Fourteen different human activities dominated by housing units (27%) were observed in river Enyau protected zones under study in Arua Municipality. Ozu-Ediofe zone corresponding directly to Arua urban center recorded the highest occurrence of the human activities (65.3%) which greatly reduced the macrozoobenthic invertebrate diversity (Hʹ=1.2) and caused pollution of river Enyau (BMWP=26.0) along that zone. The downstream zones, Onduparaka (Hʹ =2.24, BMWP=68.6) and Onduparaka-Ozu (Hʹ=1.57, BMWP=46.9) sites were both moderately polluted. On the other hand, the upstream zones i.e. Ediofe-Pajulu Bridge (Hʹ=2.52, BMWP=132.9) and Ragem Technical Institute (Hʹ=2.48, BMWP=96.2) were unpolluted and slightly polluted respectively. Hence, the implementation of the existing river bank management guidelines should be strengthened in Arua Municipality to ensure good quality of river Enyau and its sustainability.
