Abstract

The conversion of vegetation land cover contributes to the retention of solar radiation in the environment, resulting in the formation of the urban heat island. This study analyses the distribution pattern of urban heat island in the traditional core of Ibadan amidst the rapid urbanization experienced. The remote sensing tool was used to analyse the trend of land surface temperature, normalized difference built-up index, and normalized difference vegetation index for the traditional Ibadan's core between the year 2000 and the year 2020. This reveals that increasing built-up areas will continue to strengthen the effects of urban heat island in the traditional core of Ibadan, while vegetated land covers will weaken the effects of urban heat island. This is because anthropogenic activities resulting from rapid urbanisation has adversely altered the natural landscape in the traditional core of Ibadan. This alteration manifests in converting vegetation land covers into physical developments and other impervious surfaces by the increasing urban population. Thus, increasing the land surface temperature. The maximum average land surface temperature of 35.34℃, 36.62℃ and 31.86℃ were record for the years 2000, 2013 and 2020 respectively. This study further recommends that urban greening and proper urban planning should be encouraged in the traditional core of Ibadan. Keywords: Land Surface Temperature, Normalized Difference Built-up Index, Normalized Difference Vegetation Index, traditional core, urban heat island

Ayobami Abayomi Popoola, SARCHI CHAIR FOR INCLUSIVE CITIES UNIVERSITY OF KWAZULU-NATAL SOUTH AFRICA

Ayobami Popoola is a trained Geographer and now an Urban and Regional Planner with a lifelong interest in how planning and plans shape Human Wellbeing and Livelihood. This He displayed in His Ph.D. research in the Department of Town and Regional Planning, UKZN where He researched Physical Development and how it impacts household livelihood. His study explains household wellbeing from the tripod of governance, infrastructure, and planning. He is widely published in highly-rated books journals published by reputable international publishers. Most of his publications are focused on inclusivity, rural, city, land-use planning, food security, climate change, environmental and sustainable planning and management, human livelihood, and wellbeing. Dr. Popoola is was a part of the team in the SARChI Chair for Inclusive Cities project, School of Built Environment and Development Studies, UKZN. The research chair is funded by NRF and South African Cities.

Hangwelani Magidimisha-Chipungu, SARCHI CHAIR FOR INCLUSIVE CITIES UNIVERSITY OF KWAZULU-NATAL SOUTH AFRICA

Professor Hangwelani Magidimisha-Chipungu is an academic in the Department of Town and Regional Planning, University of KwaZulu-Natal (UKZN). She is an NRF-rated researcher and the first black-female South African born to graduate with a PhD in Town and Regional Planning from UKZN. She is also the first black South African born women to be appointed Associate Professor in Town and Regional Planning at UKZN with a Masters in the same field and a degree in Geography and Environment – both from UKZN. She is also a co-general rapporteur for 57th ISOCARP Congress to be hosted in Doha. Prof Magidimisha Chipungu is the chair of the organizing committee for the International Symposium on Inclusive Cities. She is Chief Editor of the Journal of Inclusive Cities and Built Environment. She continues serving on several boards locally and internationally with a focus on the built environment. She has won numerous excellent awards, including the Vice-Chancellor Research Award at the University of Kwazulu-Natal. She is also recognized by The Planner Magazine (for the royal institute of town planner) based in the UK as the most influential woman in 2021. She is currently co-PI in an inclusive city project with a focus on southern Africa countries such as South Africa, Malawi, Zambia, Mozambique, and Namibia Prof. Magidimisha-Chipungu record of service spans but not limited to the City Planning Commission for eThekwini Municipality, advisory committee of Cooperative Governance and Traditional Affairs (COGTA-KZN), member of KwaZulu-Natal Tribunal and up to late a Board member of SACPLAN. In view of a long history excellence, she was recently appointed as the first SARChI Chair in Inclusive Cities in South Africa. The Chair is co-funded by the National Research Foundation (NRF) and South African Cities Network. The Chair is the first in the Built Environment Cluster at UKZN and it is focused at investigating issues around city inclusivity. Her research and publications record spans the authoring and co-authoring of a number of books, book chapters and peer-reviewed journal articles in both local and international publishing outlets. Recently she has co-edited a book on Urban Inclusivity with a focus on Southern Africa
