Relationship between Urban Growth and Temperature Rise in Gwagwalada Abuja, Nigeria

Abstract

Urbanization can be seen as an increase in the proportion or share of the population residing in urban area as opposed to rural areas. The spatial dimension of urban growth pattern could be perceived to as negative which could have irreversible impact on the sustainability of the environment and human. This paper aimed at assessing the relationship between urban growth temperature rise in Gwagwalada area of Abuja. Landsat Thematic Mapper (TM), Enhanced Thematic Mapper Plus (ETM+) and Landsat- 8 Operational Land imager (OLI) images of 2010 and 2021 were used. Land use land cover maps were generated using supervised classification. The study revealed that for the past 12 years, Gwagwalada has been experiencing tremendous urban growth. The study showed that built up is increasing at an annual rate of over 8.7% while the land surface temperature (LST) has increase by 5℃ between 2010 and 2022. The study also recommends that biophilic design should be adopted by the Federal Capital Territory Administration (FCTA) administration in Gwagwalada revised master plan to help mitigate LST and improve the livability of the resident.
