Sustainable City or A Slum: An Interrogation of The Cognitive Process of a Complex City

Abuja, the Federal Capital Territory of Nigeria, has evolved from a meticulously planned city into one of the most prominent urban centers in West Africa.Yet, it struggles with challenges such as urban sprawl, informal settlements, infrastructural deficits, and social inequalities, which hinder its path toward sustainability.This paper interrogates the cognitive processes underpinning Abuja's urban planning, governance, and development trajectory, examining whether the city can achieve sustainable growth or risks degenerating into a sprawling slum.Using a mixed-method approach, this study analyses urban planning policies, socioeconomic patterns, and governance frameworks to assess the city's sustainable development potential.Results from questionnaires administered to 750 participants across Abuja highlight the widening gap between planned and unplanned areas.This paper concludes by recommending governance reforms, equitable infrastructure investments, and participatory planning to mitigate Abuja's developmental challenges.
