Urban development is occurring in many Sub-Saharan Africa cities and rapid urbanization is underway in the East African city of Addis Ababa, Ethiopia. In an effort to address urban poverty and increase homeownership opportunities for low and middle-income residents, the City Administration of Addis Ababa initiated a large-scale housing development project in 2005. The project has resulted in the completion of 175,000 units within the city with 132,000 more under construction. To understand the impacts of both rapid growth and the housing program’s impact on the city’s urban form, we compared the type and distribution of land uses in Addis Ababa, Ethiopia, between 2006 with 2016 using hand-digitized, ortho-rectified satellite images in Geographic Information Systems (GISs). While residential density has increased, overall density has decreased from 109 people/ha to 98 people/ha. We found that between 2006 and 2016, land occupied by residential housing increased from 33% to 39% and the proportion of informal housing decreased from 57% to 38%. Reflecting the country’s economic prosperity, there was a dramatic increase in the presence of single family housing, particularly on the city’s western side. In 2006, only 1% of residential areas were occupied by high-rise condominiums (4 floors or greater) and this increased to 11% by 2016. The majority of the new, higher density residential developments are located near the eastern edges of the city and this outlying location has significant implications for residents, infrastructure construction, and future development.

Urban forestry and green spaces have less priority in urban planning. This research intends to assess the policy and planning of urban green spaces with their potential implementation status and challenges in planning and implementation. The general objective is to assess urban green space planning, policy, and implementation strategies and challenges encountered in Addis Ababa. The primary data was collected through key informant interviews, focus group discussions, and field observation; secondary data from a literature review along with examining policy and masterplans of Addis Ababa has been used. The mapping of stakeholder and institutional arrangements is analyzed using stakeholders’ consultation. Triangulation is used for data validation and analysis. Existing policy and proclamations must be supported by legislative regulations and implementation frameworks that provide the basis for concrete action plans. The incentives stipulated by the forest policy are not implemented to the required level. The 10th masterplan of the city (2017–2027) shows that the city will increase its green area development and public recreation coverage to 30% by 2020. Principles, such as multi-functionality, connectivity, green-grey interaction, and social inclusiveness, are considered in the planning of the green space development in the 10th masterplan. The research concludes that regulations and directives are not clearly drafted by responsible bodies, and low enforcement is hardly applied with respect to the green space development of Addis Ababa.

Urban parks provide various environmental, socio-cultural and economic benefits, also called ecosystem services, as well as challenges. Urban park planning and management needs to consider the perception and attitude of people towards the benefits, challenges and quality of the parks. However, such information is largely lacking for cities of Sub-Saharan Africa. The objectives of this study are to understand the perception and attitude of residents towards the benefits, challenges and qualities of neighborhood parks in a formal settlement area in Addis Ababa, Ethiopia, and to investigate whether these aspects are affected by the socio-demographic characteristics of respondents. Data were collected through a household survey (n = 398) and three focus group discussions. Data were analyzed using descriptive statistics and Chi-square tests. The focus group discussion resulted in the selection of 18 ecosystem services (benefits) and five challenges. Supported by a very high response rate (96.6%), the household survey shows that respondents recognize the environmental, socio-cultural and economic benefits provided by neighborhood parks, but that the socio-cultural and environmental benefits are perceived as more important than the economic benefits. The socio-demographic characteristics of age, gender and education level were found to have no significant effect on perceptions or attitudes. The cost of managing neighborhood parks and the attraction of nuisance insects were the two most important challenges, respectively. The majority of respondents rated the quality of the existing neighborhood parks excellent or good, with the existing safety condition and the presence of high plant diversity receiving the highest number of high scores. The availability of park facilities was the aspect of park quality considered poor by the most respondents. This study highlights the importance of place-based studies for assessing the perceived benefits that attract people to use urban parks, as well as the challenges that deter use. One important lesson that cities in Sub-Saharan Africa could draw from the development and management of neighborhood parks in Addis Ababa is the vital importance of public participation in urban park development and management.

The Mekelle city region is facing severe ecosystem degradation. The study area has experienced unprecedented land-use dynamics over the past 47 years, but the effect of these dynamics on ecosystem-service values remains unknown. Estimating the various ecosystem services from a city region perspective has not been attempted so far. The rationale of this study was to estimate the spatial–temporal ecosystem-service value variations. The methodology employed was land-use/land-cover (LULC) datasets of remotely sensed datasets of the years 1972, 1984, 2001, 2012, and 2019, and ecosystem service value coefficient, expert focus group discussion, and document review were used. The digital satellite images were processed, classified, and analyzed using Earth Resource Development Assessment System (ERDAS) Imagine. Computations of changes in the land-use categories were made using Arc GIS 10.5.1, Eviews for time series data analysis, and XLSTAT analytical tools were used. Over the whole study period from 1972 to 2019, a loss of USD 128.6 million was observed, which is a reduction of 501.9%. The study shows that due to land-use changes, the total ecosystem service value is decreasing annually, suggesting that much more severe ecosystem degradation is due to occur. The results are relevant to policy development and indicate that ecological restoration is the best option in the study area.
