From Stationarity to Resilience: A Framework for Climate-Informed Engineering Practice in Africa

Résumé fourni par la source

Climate change presents a critical threat to the sustainability of African infrastructure, requiring an estimated $50 billion annually for adaptation. This paper evaluates the systemic shift required in engineering practice to transition from historical climate parameters to non-linear, predictive resilience models. By analyzing the vulnerabilities of African transportation, energy, and water systems-exemplified by the $1.4 billion loss during Cyclone Idai-we identify the technical obsolescence of current building codes. Through a multi-dimensional analysis of nature-based solutions, smart sensor networks, and climate-resistant coastal engineering, this study proposes a framework for integrating environmental flexibility into professional standards. Using case studies from Lagos and Abuja, Nigeria, we demonstrate the efficacy of sustainable drainage and green construction in mitigating flood risks. The findings underscore the pivotal role of professional engineering institutions in driving the policy advocacy and capacity building necessary to future-proof the continent’s-built environment.
