    Middle East and North Africa (MENA) region possesses immense capacity for renewable energy generation. Despite the potential, most countries in the region are yet to fully embrace renewable energy. Non-renewable sources still dominate their energy mix. This study examines the interplay between urbanization, renewable and non-renewable energy consumption, and environmental quality in the six Middle Eastern and North African countries from 1990 to 2021, using the mean group (MG), the mean group dynamic least squares (DOLSMG), the common correlated effect (CCE), augmented mean group (AMG) and the cross-section augmented ARDL (CS–ARDL). Accounting for urbanization, and economic growth, the findings of DOLSMG indicate that while renewable energy and manufacturing activities significantly contribute to environmental quality, urbanization and human capital development significantly contributes to environmental degradation. The CS-ARDL short-term and long run estimation result showed that manufacturing activities significantly contribute to environmental quality, When examined by country, it was found that there is a unidirectional causal relationship from economic growth, manufacturing value added, urbanization, human capital development to dioxide emissions in Saudi Arabia. While there is a unidirectional causality from manufacturing value added to dioxide emissions in Jordan, and a unidirectional causality from urbanization to dioxide emissions in Tunisia.

    Modelling the dynamics of urbanization for urban sustainability in West Africa
    (Elsevier B.V., 2024) Radoine, Hassan; Bajja, Salwa; Dakyaga, Francis; Çelik, Ali; Kamana, Alanda; Yakubu, Hassan; Chenal, Jerome
    The West African region, one of the largest urban agglomerations in Africa has over decades experienced rapid rate of urbanization. The urbanization processes have been associated with manifold environmental and socioeconomic challenges including inefficient urban infrastructure, unaffordable housing, poor sanitation and informal settlements. Urban scholars following the rise of urbanization and climate change in West Africa have advocated for policies and programmes towards the reduction of carbon footprints and sustainable human settlements, while emphasizing on the needs to plan for urban sustainability. Yet limited studies have so far analysed the dynamics of urbanization in West Africa, especially in relations to sustainability. Motivated by the evolving debates on urban sustainability, this study contributes to urban planning discourse, by exploring the dynamics of energy consumption, gross domestic product, employment levels and productivity in six countries in West Africa and demonstrate the implications for urban sustainability. Using the Seemingly Unrelated Regression (SUR)-Mean Group (MG) model, we analysed annual data from 1991 to 2018 of Urban Population Growth, Gross Domestic Product, Energy Consumption, and Greenhouse gas emissions. The study revealed variation across the selected countries in terms of rate of urbanization, productivity, and energy consumption. The results suggest the need for commonalities as well as differentiated approaches towards improving urban environmental quality for urban sustainability. Furthermore, while there is a need to promote green urban infrastructure, concerted efforts are required towards promoting sustainable urban environmental quality. © 2024 The Authors
