“…The analysis showed a variability of +5.32 o C and +1.03 o C maximum and minimum temperature in the Nguru between 2001 and 2021 respectively, as shown in Table 6. The difference was found not to be sizeable in comparison to the studies by Ifatimehin (2007) and Qiquan and Jiayi (2017).…”

“…Variations in minimum and maximum temperatures are alleged to have occurred within Nguru as a result of a massive drop in vegetative cover and an upsurge in built-up areas. The LST research findings are consistent with those ofIfatimehin (2007) who observed that Surface Urban Heat Island (SUHI) is higher in the city center and decreases as one moves outward, as well as the research findings of(Aslan and Koc-San, 2016;Khaled, et al, 2015; Zaharadeen et al, 2016).…”

The effects of urban heat islands (UHI) have received a lot of attention because they have a huge impact on human health and environmental resource sustainability. A key moment in the history of mankind has been urbanization, and there is no doubt that the world is rapidly urbanizing, which is causing temperature changes. The relationship between climate change and rapid urbanization in Nguru Local Government Area, Yobe State, Nigeria, is investigated in this paper. The study used remote sensing data to reveal the extent of urban microclimate change trends over the next two decades (2001–2021). Thus, the microclimate temperature increased by nearly +5.32 °C in 2021 (39.39°C) compared to 34.07°C in 2001. Furthermore, the minimum temperature in 2001 was 22.33 °C, while that of 2021 was 23.36 ℃. The built-up area increased by 556.73%, from 446 hectares in 2001 to 2,483 hectares in 2021. Accelerated urbanization and the city's blue and green facilities, which are not preserved or safeguarded due to a poor planning system, are to blame for these modifications to the urban climate and design. The study aimed to determine the relationship between urbanization and urban heat islands in Nguru local government area, Yobe State, Nigeria. The picture of the situation in Nguru sheds light on the enormous challenges that cities in developing countries encounter in dealing with local and global climate change-related risks. Indeed, this situation necessitates an integrated strategy to address climate change both within and outside of cities. Policymakers must increase spending on urban planning, fund, adaptation of approaches through urban planning, and strengthen urban planning institutions.

Limestone mining and cement production at Yandev, Nigeria commenced in 1980 without an environmental impact assessment (EIA) to ascertain the extent of impact these activities could bring to bear on the physical and living conditions of the host environment. This study was carried out to assess the impact that mining of limestone and production of cement has inflicted on the quality and density of vegetation within the study area about 32 years since production commenced. Multi-temporal satellite imageries of the study area (Landsat for 1976(Landsat for , 1986(Landsat for , 1996 and Nigeriasat-1 for 2006), ILWIS Academia 3.3 and SPSS Version 15 were used for data analyses. Landuse and landcover (LULC) change detection; land surface temperature (LST) extraction; and normalized differentials of vegetation index (NDVI) estimation were carried out. The paired t-test was used for landcover data analysis. The study discovered first, that LULC changes occurred with built-up area increasing from 0. (1976, 1986 and 1996) while NDVI signifies decline in quality and health status of vegetation cover over the study period (1986, 1996 and 2006). The study concludes that there is rapid decline in density and quality of vegetation cover within the study area. Ameliorative measures are recommended to include reforestation and improvement in limestone mining methods/techniques amongst others.

Surface urban heat island (SUHI) phenomenon is caused by the increase in local atmospheric and surface temperatures in urban areas compared to the surrounding rural areas. This mainly results from the concentration of human activities and land uses such as dense transportation network, buildings. This study aims to analyze the spatial patterns of land surface temperature to quantify and understand the effects of SUHI over urban, sub-urban and rural area of Damascus. MODIS/Terra Temperature product (MYD11A2, 8 days, 1 km spatial resolution) used to study the UHI phenomenon for Damascus and surrounding areas. Therefore, a series of data were obtained on 2010 covering 8 days of months from winter and summer seasons at day and night time. The results showed that SUHI were typically presented in winter (day and night) and in summer (only night). However, it tended to be strongest during the night. This is mainly because of the buildings and commercial business establishments in Damascus are made of concrete, asphalt, and steel, which are excellent absorbers and conductors of thermal energy. Since these buildings produce higher radiate thermal heat at night time, higher temperatures were recorded.
