Abstract—It has become an increasing evident that large development influences the climate. There are concerns that rising temperature over developed areas could have negative impact and increase living discomfort within city boundaries. Temperature trends in Ibadan city have received little attention, yet the area has experienced heavy urban expansion between 1972 and 2014. This research aims at examining the impact of landuse change on surface temperature knowing that the built-up environment absorb and store solar energy, resulting into the Urban Heat Island (UHI) effect. The Landsat imagery was used to examine the landuse change for a period of 42 years (1972-2014). Land Surface Temperature (LST) was obtained by converting the thermal band to a surface temperature map and zonal statistic analyses was used to examine the relationship between landuse and temperature emission. The results showed that the settlement area increased to a large extent while the area covered by vegetation reduced during the study period. The spatial and temporal trends of surface temperature are related to the gradual change in urban landuse/landcover and the settlement area has the highest emission. This research provides useful insight into the temporal behavior of the Ibadan city. I. INTRODUCTION LOBAL warming increase is believed to be as a result of landuse/landcover change [3]. Urbanization and urban sprawl are the dominant factors in regional landscape evolution across the world, which affects climate leading to great environmental impact. Rapid urbanization results from the large-scale development of commercial, manufacturing and transportation areas, which leads to the emergence of the Urban Heat Island (UHI) effect. Urban Heat Island is a typical phenomenon of urban climates that challenge sustainable livelihood and describes the excess temperature near the ground (canopy layer) of the central urban locations as being higher than those of nearby or surrounding areas of similar elevation [11]. The characteristics of the UHI are related to both the intrinsic nature of the city, such as its size, population, building density and land uses, and external factors such as climate and weather [9]. The process of urbanization produces radical changes in the nature of the surface and atmospheric properties of a region. It involves the transformation of radiation, thermal, moisture and aerodynamic characteristics, and thereby dislocates the natural solar and hydrologic cascades. UHI has been regarded as a L.O.

One of the possible causes of UHI is the drastic reduction in the greenery areas of the cities, and increase in built-up areas brought about by population increase which can be observed in Ibadan, a rapidly developing city in Nigeria. Urban areas in Nigeria will generally experience the same exposures to climate as their surrounding country side, the urban setting- its form and socio-economic activity can alter exposure as well as impact at the local scale. Built-up areas in the cities create unique micro-climate due to the replacement of natural vegetation with artificial surfaces. This affects air temperature, wind direction and precipitation patterns, amongst others. The impact of heat waves is particularly strong in cities and towns which lead to decrease in water resource quality and quantity, increase risk of forest fire, decrease cold-related human morbidity and mortality along with reduced heating energy demand, increase flood, landslide, avalanche, and mudslide damage. There are also expected to be some indirect effects due to crop damage by heat, water or pests and increased migration pressure as people move to more climatologically acceptable regions [6]. If the relationship between city form and the extent of the UHI were known, it would be possible to identify thermally efficient models of urban development. The availability of remotely sensed data makes the research more achievable. A satellite-based methodology is used to estimate urban temperatures and to classify various landuses. Remotely-sensed thermal imagery can provide a time- synchronized grid of temperature data over a whole city, and distinctive differences in the temperatures of individual buildings [8]. The objective of this research is to integrate satellite data in analyzing urban heat island effects in Ibadan city. Landuse and temperature distributions derived from satellite data, and a Geographical Information System (GIS) are used to visualize and analyze the interactions between temperature and landuse based on the following objectives: analyzing the changes in landuse/landcover pattern; analyzing the urban heat intensity using Landsat imagery; and examining the relationship between UHI and landuse. II. STUDY AREA Ibadan city is located between latitudes 7 0 20’ and 7 0 26’ of the equator and longitudes 3 0 48’ and 3 0 56’ of the Greenwich meridian. It is directly connected to many towns as its rural hinterland by a system of roads, railways and air routes. The city is the dominant urban centre in Oyo State, the largest indigenous city in West Africa and has an overall population density of 586 persons per km 2 .
