In a significant recognition of Nigerian academia, Professors Ibidun Adelekan and Aliyu Barau have been chosen among 97 global experts to contribute as lead authors to the Intergovernmental Panel on Climate Change Special Report on Climate Change and Cities.
According to a statement, this report, which is set to be released in March 2027, marks the first of the IPCC’s seventh assessment cycle, focusing on the critical intersection of climate change and urban environments.
Associate Professor Ibidun Adelekan, a distinguished geographer from the University of Ibadan, will bring her expertise in human dimensions of global environmental change, including climate change, disaster risk reduction, and resilience, to Chapter 2 of the report.
Adelekan’s work has significantly contributed to understanding climate impacts on vulnerable communities in West Africa, making her an asset in shaping climate adaptation strategies.
Also, the Dean of the Faculty of Earth and Environmental Sciences at Bayero University, Kano, and the West Africa Hub Director of the Urban Climate Change Research Network (UCCRN) affiliated with Columbia University, Professor Aliyu Barau, will contribute to Chapter 5.
According to the statement, Barau’s research focuses on urban planning, sustainability, and climate resilience, particularly within rapidly urbanising African cities. His role in this report underscores the importance of integrating urban development with climate adaptation policies.
“The selection process, conducted during the IPCC’s 61st Session in Sofia, Bulgaria, was rigorous, emphasising scientific, technical, and socio-economic expertise, along with geographical and gender balance. Out of 1,201 nominations from national focal points and observer organisations, 97 experts were chosen, with over half being women and a significant proportion representing developing countries and economies in transition,” the statement read.
According to the Co-Chair of the IPCC Working Group II, Winston Chow, the report is a critical “call to action” aimed at harnessing cities’ potential to tackle climate challenges while ensuring resilience, inclusivity, and sustainability.
On her part, the Co-Chair of Working Group III, Joy Pereira, highlighted the unprecedented global interest in contributing to this vital report, reflecting the growing body of scientific literature on climate change and urbanisation.
Furthermore, the IPCC’s Special Report on Climate Change and Cities will provide a comprehensive assessment of the latest science, examining climate impacts, risks, and mitigation strategies for urban areas. With over half of the global population living in cities—a figure expected to rise significantly by 2050—the report’s findings will be crucial for policymakers, urban planners, and climate activists worldwide.
It mentioned that the involvement of Nigerian scholars Adelekan and Barau underscores the critical role African researchers play in global climate discourse. Their contributions will not only elevate Nigeria’s profile in international climate research but also ensure that African urban experiences and solutions are integral to global strategies.
“As the draughting process begins, the scientific community is encouraged to engage as expert reviewers, with a call for participation in the review of the first order draft slated for the second half of 2025. The IPCC’s inclusive approach aims to enrich the report with diverse insights, ensuring its relevance and applicability across varied urban contexts,” it concluded.
