A recent climatological study conducted by Taiwo Ogundeji, a PhD holder in Environmental Systems and Climate Change from the Federal University of Agriculture, Abeokuta, has highlighted growing concerns about heat stress within the urban centre of Abeokuta.
Ogundeji explained that the study, which analysed heat stress hotspots using heat index (HI) computations, found that temperatures in the city’s urban core are significantly higher than those in its surrounding areas.
Abeokuta is the largest urban centre and capital of Ogun state in southwestern Nigeria. The city is known for its rich cultural heritage, historic sites like the Olumo Rock, and its vibrant markets and trade centres.
He attributed this disparity to intense economic activities, industrial engagements, and a high population density, all of which contribute to increased heat absorption and retention.
According to the climate change expert, certain areas within the city have been classified under the “Extreme Caution” HI categorisation, signifying an elevated risk of heat-related illnesses.
He identified factors such as reduced evapotranspiration, decreased albedo, intensified anthropogenic activities, and rapid changes in land use and land cover as key contributors to the rising heat stress levels.
Despite the high HI values recorded in the city centre, Ogundeji noted that “Abeokuta has not yet experienced extreme heat wave (HW) events”.
He said “the absence of consecutive days exceeding critical temperature thresholds” suggests that, for now, “the city’s heat stress remains within manageable limits”.
However, he stressed the importance of continuous monitoring to prevent potential future crises.
The research also revealed that heat index incidences were more frequent during the dry season, underscoring the need for proactive mitigation strategies.
Ogundeji recommended sustainable environmental practices such as extensive tree planting, discouraging bush burning, and designing buildings with cross-ventilation to enhance airflow and reduce indoor heat buildup.
He also warned that as global temperatures continue to rise due to climate change, urban centres like Abeokuta must implement adaptive measures to protect public health and sustain economic productivity.
Without effective intervention, he cautioned, the risks associated with “prolonged heat stress could escalate”, affecting both human well-being and the city’s long-term resilience.
Findings from the study highlight the urgent need to integrate climate-conscious urban planning and environmental management strategies in rapidly expanding cities like Abeokuta.
