In Ethiopia, urban areas are defined basically as places having a minimum population of 2,000. The current coverage of urban areas in the country is less than 20%, and even the majorities are small towns that account more than 85% of the urbanized areas in the country. However, urbanization in the country is increasing rapidly, at a rate of 4.63% annually. Spatially, the highest urbanization ratios occur in small towns surrounding the Ethiopia's capital city, Addis Ababa. Still, the recently urbanized areas are characterized as shanty, slum and spontaneous. On the other hand, the current rate of urbanization in the country indicates that there will be more urbanized areas in the future, which need better urban planning and management. Therefore, the purpose of this research was to identify the key drivers of the development of Ethiopia's urbanization, and to identify the management gaps that could help to predict future urbanization hotspots and trends from their early stages. Methodologically, both primary and secondary data sources were systematically applied: current urban planning and related documents, as well as land-use plans, and furthermore, high resolution historical satellite imageries of 2005, 2008 and 2018 from Google Earth Pro were analyzed. Complementary, and for validation purposes interviews and focus group discussions with experts were carried out between 2018-2021, together with on-site investigation. The results show that the drivers for the emergence of spontaneous urban development in Ethiopia relate primarily to socio-cultural components, such as in the case of worshiping places, local markets, educational and administrative centers. Physical infrastructure, such as roads played also a significant but subordinate role in the intensification of such developments. Our results demonstrate how an ineffective management of these factors has contributed to a dysfunctional urban growth. Finally, a green field level proactive planning approach is proposed and commented.
在埃塞俄比亚,城市地区基本上被定义为人口至少达2000人的地方。该国目前城市地区的覆盖率不到20%,而且大多数是小镇,占全国城市化地区的85%以上。然而,该国的城市化进程正在迅速加快,年增长率为4.63%。在空间上,埃塞俄比亚首都亚的斯亚贝巴周边的小镇城市化率最高。不过,最近城市化的地区具有棚户区、贫民窟和自发形成的特点。另一方面,该国目前的城市化速度表明未来将有更多的城市化地区,这需要更好的城市规划和管理。因此,本研究的目的是确定埃塞俄比亚城市化发展的关键驱动因素,并找出有助于从早期阶段预测未来城市化热点和趋势的管理差距。在方法上,系统地应用了主要和次要数据源:当前的城市规划及相关文件以及土地利用规划,此外,还分析了谷歌地球专业版提供的2005年、2008年和2018年的高分辨率历史卫星图像。作为补充,并为了进行验证,在2018年至2021年期间与专家进行了访谈和焦点小组讨论,并进行了实地调查。结果表明,埃塞俄比亚自发城市发展出现的驱动因素主要与社会文化因素有关,比如宗教场所、当地市场、教育和行政中心等情况。诸如道路等物理基础设施在这种发展的强化过程中也发挥了重要但次要的作用。我们的结果表明了对这些因素管理不善是如何导致城市发展功能失调的。最后,提出并评论了一种绿地层面的积极规划方法。
