Rapid urbanisation is precipitating wide-ranging and often irreversible changes in cities and at the shifting peri-urban areas around the world. As a significant factor of change in the 21 st Century, urbanisation is irreversibly transforming everything on its path-air, land, water, and ecology, including institutions, customs, and lifestyles. The subject scope of urbanisation research is therefore quite wide and diverse. Yet, urbanisation-induced attritions and substitutions of customary tenure practices, coupled with the associated politics and resistances, remain utterly overlooked. Using a mixed method approach (involving desktop research, remote sensing data and stakeholder interviews), this paper examines the clashes between customary tenure regime and statutory practices dictated by urban laws, and how different stakeholders are appropriating them both to promote and resist displacement or eviction. Amidst growing encroachment pressures on peri-urban communities in Nigerian cities, a new imperative for enhanced tenure security and integrated planning approach are proposed.
