Achieving sustainability in civil engineering projects in Nigeria: a case for climate change

Abstract

This paper investigates the nexus between infrastructure and climate change in Nigeria, particularly amidst rapid urbanization. Employing a qualitative methodology, the study delves into industry perspectives, prevailing sustainable practices, and recommendations through in-depth interviews with ten seasoned professionals spanning Nigeria's six geopolitical zones. Study findings underscore a growing awareness of climate change, manifested through tangible impacts like flooding, heatwaves, loss of livelihood, biodiversity loss, desertification, and health repercussions. However, a noticeable knowledge gap persists, particularly concerning the implications for the built environment. Encouragingly, participants are already incorporating certain sustainable practices such as green land conservation, renewable energy, and low-carbon materials, albeit predominantly in highway and building projects. The study highlights an urgent imperative to expedite the construction industry's shift toward climate-conscious practices. This necessitates robust interventions encompassing awareness campaigns, legislative measures, incentives, and fostering public-private collaboration. The study underscores that as Nigeria progresses towards its infrastructure development ambitions, overlooking the sector's environmental implications risks exacerbating emissions.
