Current planning strategies for future urban development often target issues such as housing, transport, water, and infrastructure; but very few strategies comprehensively consider the urban climate and its interaction with the built environment as well as the resultant effects. Thus, this research investigated the climate change impacts in an urban area with a view to recommend measures to manage the emerging effects of climate change. For the purpose of this study, the study area is Ikeja local government area- a rapidly growing urban centre with an annual growth rate of 50%. The research design adopted for the study was survey research which involved site visitation for data collection, and analysis. The local government was subdivided into 3 development zone from which the sample size of 450 was drawn using simple random sampling technique. Data was sourced from the respondents using questionnaire, spatial data was sourced from trusted online sources, alongside other secondary data. Collected data from questionnaire was analysed using Statistical Package for social sciences (SPSS) version 22 while the spatial data was analysed using ArcGIS version 10.5. The result of the analysis revealed that Ikeja Local Government Area was densely populated. Majority of its residents are educated with 43.8% of the respondent having tertiary education. According to the study, identified climate change impacts on households include flooding, health risk, high temperature and dryness of well. The results from the GIS land cover analysis revealed that built up area in Ikeja local government have increased form 10.75% of the total coverage of the local government in 1980 to 92.11% in 2019. Accordingly, the climate of the area is expected to be significantly impacted. Thus, it was recommended that the local government need to develop information based system to manage urban growth in the area, initiate vulnerability assessment of the city and engage in public awareness on the importance of land use planning in mitigating effect of climate change.
