IMPACT OF URBAN DEVELOPMENT ON CLIMATE CHANGE IN SOUTH-WEST, NIGERIA
Keywords:impact, urban development, climate change, South-West Nigeria
The built environment or structural aspects of cities, streets, buildings, and infrastructure systems contribute significantly to the emission of greenhouse gases. 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. The research design adopted for the study was survey research which involved site visitation for data collection and analysis of collected data. 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, climate data was sourced from the Nigerian Metrological Agency (NIMET), 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 spatial data was analysed using ArcGIS version 10.5. The GIS land classification model that was used 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 which is expected to have significant effect on the climate of the area. In conclusion, 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.
