Cities—especially those with substantial poor populations—will face increasingly severe challenges in tackling the impacts of global environmental change (GEC). As economic dynamos and increasingly important population concentrations, cities both contribute substantially, and often are very vulnerable, to the impacts of GEC. This applies strongly in Africa, one of the world’s poorest regions. The inability of even a relatively wealthy and

Climate Change-Urbanization Nexus: Exploring the Contribution of Urbanization on Carbon Emissions in East Africa2019 •
It is perceived that east Africa, like the rest of the continent, is only a victim than a contributor of climate change, a perception that motivated this study that explores the contribution of urbanization on carbon emissivity in the east African region. We used panel data for selected countries in the region and conducted analysis on the urbanization-carbon emissions models that determines the presence of an Environmental Kuznets Curve hypothesis. Parametric and semi-parametric fixed-effects models analyses were also executed and results compared. Our results strikingly reveal that urbanization and economic growth are responsible for continued environmental deterioration in the region. We recommend future studies to focus on urbanization and how countries in the region can grow without necessarily impairing the environment.

In Africa, unregulated urbanization is associated with variety of policy issues spanning demographic, economic, and environmental concerns occurring in the context of massive rural-urban migration and rapid urbanization. These lead to structural weaknesses and even breaking points in cities that are not adequately prepared for the uncontrolled influx of rural populations seeking to improve their lives. The growing consensus is that this situation poses one of the major threats to environmental security in the developing world, and that they impact the poor and therefore the most food insecure to the greatest extent. Urbanization is one of the most significant trends in Africa at present, with rural populations migrating at unprecedented rates to urban hubs in search of employment and economic growth. The effect of this includes, among others, the growing of slums, pressure on infrastructure and the social problems, including security that accompany unemployment in an urban setting. ...

In search of missing links: urbanisation and climate change in Kano Metropolis, Nigeria2019 •
Africa is blessed with natural and mineral resources, but exploitation of these resources has led to extreme pollution of the environment. Population growth and urbanization due to developments have also contributed immensely to the current pollution in Africa. Traffic emissions, transported dust and open burning are all significant contributors to air pollution in Africa. The Sahara desert is a major source of transported dust, especially during the harmattan season in West Africa. Mercury emissions are very high in South Africa due to coal combustion and gold mining. Air pollutants may contaminate water and soil through atmospheric deposition. However, the major pollution sources for surface waters are the urban and industrial discharges of untreated effluents into the water. A few African countries have standards for effluent discharge into surface waters, but it is unknown whether these standards are being enforced. Though groundwater sources in wells and boreholes are the major sources of drinking water for the African populace, the biological water quality of these groundwater sources is mostly low in the region due to close proximity to sanitary facilities. Identified sources of soil pollution in Africa include agricultural activities, mining, roadside emissions, auto-mechanic workshops, refuse dumps and e-waste. Oil spills are a major problem in oil-rich African countries such as Nigeria and Angola. Agricultural activities are the lowest impacting the soil in Africa, while e-waste recycling was the highest with Pb, Cu and Zn at extremely high concentrations ([1%). There is a need for proper regulation of environmental pollutants in Africa.

Geospatial Assessment of Environmental Impact of Urban Growth in Akure South, Ondo State, Nigeria2024 •
This comprehensive study examines the environmental impact of urbanization in Akure South, Ondo State, Nigeria, using a fusion of geospatial and microbiological analyses. Employing Landsat imagery from 2000, 2011, and 2022, processed through ArcGIS 10.8 and TERRSET software, the study maps and quantifies urban expansion and land use changes. Methodology: The research concurrently leverages, microbiological techniques to assess air pollution, as well as water and soil contamination levels. Findings: The result highlighted an increase in built up area from 9.31% in 2000 to 17.45% in 2011 and 29.54% in 2022, which is evident particularly in Akure township area, correlating with a notable decline in environmental quality. Pollution hotspots, identified through rigorous spatial analysis, point to areas severely impacted by urban growth and high level of air pollution, as well as water and soil contamination. In addition, Land Use/Land Cover (LULC) prediction shows that built up area will likely cover about 30.09% by 2042. These findings underscore the urgent need for strategic urban planning and robust pollution control measures. Unique contributor to theory, policy and practice: The study advocates for a balanced approach to urban development, integrating environmental sustainability to mitigate the adverse effects of rapid urban growth. This research contributes to the broader discourse on urbanization's environmental impact, offering valuable insights for policymakers and urban planners in similarly developing regions of the world.
