Integrating Circular Economy Principles in Urban Development for Sustainable Cities in Nigeria: Lessons from Global and Local Case Studies

Nigeria, Africa's most populous country, faces significant urbanization challenges including waste management, resource scarcity, and environmental degradation. This paper explores the integration of Circular Economy (CE) principles in urban development to foster sustainable cities in Nigeria. By examining case studies and best practices from global and local perspectives, including insights from Lebanon's experiences amid its economic crisis, the paper provides strategic recommendations for policymakers, urban planners, and stakeholders to implement CE principles effectively in Nigerian urban contexts. Lebanon's strategic adaptation of CE principles, particularly in response to its severe economic and energy crises, demonstrates the potential for CE to enhance economic resilience and sustainability under challenging conditions. This experience offers critical lessons for Nigeria, as it also faces similar urbanization and sustainability challenges.
