“…Because, a significant amount of natural and plantation forests, shrub lands and croplands are destroyed and replaced by artificial impervious surfaces which could be the source of an enormous environmental influences on this planet (Miles & Esau, 2020;Zhou et al, 2016;Fabeku & Balogun, 2018;Jiang et al, 2015). Specifically, this situation causes a fall in evapotranspiration through photosynthesis, increase in run-off and LSTs which in turn increases the occurrence of Urban Heat Island (UHIs) (Farina, 2012;Ibitoye et al, 2017;Singh et al, 2014;Ye et al, 2017). UHI refers to an intensification in LST and has a substantial effect on urban climate, human wellbeing, biodiversity, and sustainable development (Chen et al, 2017;Qiao et al, 2020;.…”

The aggravating deforestation, industrialization and urbanization are increasingly becoming the principal causes for environmental challenges worldwide. As a result, satellite-based remote sensing helps to explore the environmental challenges spatially and temporally. This investigation analyzed the spatiotemporal discrepancies in Land Surface Temperature (LST) and the link with elevation in Amhara region, Ethiopia. The Moderate Resolution Imaging Spectroradiometer (MODIS) LST data (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019)(2020) was used. The pixel-based linear regression model was employed to explore the spatiotemporal discrepancies of LST changes pixel-wise.Furthermore, Sen's slope and Mann-Kendall were used for determining the extent of temporal shifts of the areal average LST and evaluating trends in areal average LST values, respectively.Coefficient of Variation (CV) was calculated to examine spatial and temporal discrepancies in seasonal and annual LST for each pixel. The distribution of average seasonal LST spatially ranged from 43.45-16.62℃, 39.89-14.59℃, 50.39-21.102℃ and 43.164-20.39℃ for autumn (September-November), summer (June-August), spring (March-May) and winter (December-February) seasons, respectively. The seasonal LST CV varied from1.096-10.72%, 0.7-11.06%, 1.29-14.76% and 2.19-10.35% for average autumn, summer, spring and winter seasons, respectively. The seasonal spatial LST trend varied from -0.7-0.16, -0.4-0.224, 0.6-0.19 and -0.6-0.32 for average autumn, summer, spring and winter seasons, respectively. Besides, the annual spatial LST slope varied from -0.58-0.17. An insignificantly declining trend in LST shown at 0.036℃ yr -1 , 0.041℃ yr -1 , 0.074℃ yr -1 , 0.005℃ yr -1 in autumn, summer, spring and winter seasons (P<0.05), respectively. Moreover, the annual variations of mean LST decreased insignificantly at 0.046℃ yr -1 . Generally, the LST is tremendously variable in space and time and negatively correlated with an elevation.

“…It lies between latitudes 7°07'N and 7°37'N and longitudes 5°06'E and 5°38'E (Figure 1). Akure, with a land area of approximately 991km², is the capital city of Ondo State with two Local Government Areas (LGA); Akure South and Akure North LGAs (Ibitoye et al, 2017). The aboriginal people are of the Yoruba tribe, though there are other tribes such as Igbira, Igbo, Edo and Hausa, among others.…”

“…Major economic activities include farming, trading, tourism, and civil service. Also, the inhabitants of Akure engage in scale indigenous industrial works such as cloth weaving, gaari production, block and bakery activities (Eades, 1980;Daniel, 2015;Ondo State Ministry of Agriculture and Natural Resources, OSMANR, 2015;Ibitoye et al, 2017). According to the National Population Commission of Nigeria (NPC), the population of Akure in the last national headcount conducted in 2006 was 353,211 (NPC, 2006).…”

There is a general paucity of explanations for the emerging social and spatial changes in the pattern and socio-economic traits of urban residential housing units in Nigeria. Hence, this study examined the spatial pattern of residential neighbourhoods; assessed the quality of residential housing units; and evaluated the correlation between the socio-economic position of respondents and housing quality in Akure, Nigeria. Data were derived from the household questionnaire, remotely sensed data (Landsat 8 OLI/TIR, 2021), a Google Earth map, a Street Map of Akure Township, and personal observations. The study adopted a step-wise sampling technique to select 383 samples from 139,069 heads of households in Akure in 2021. Data were analysed using percentage distribution, Pearson Correlation Coefficient, and t-test. Results indicated varying housing qualities across three residential zones in Akure, Nigeria; houses in the low-density residential areas were of better quality than the other residential zones. The quality of houses occupied was influenced by the type of occupation, level of education and average annual income of residents. The study concluded that inadequate housing facilities are fundamental to the observed deteriorating housing qualities in the study area. Therefore, the study suggested improvement of the existing infrastructures and the provision of new ones in the study area. The main contribution of this study is to proffer solutions for a sustainable housing delivery system to facilitate a better quality of life in Nigerian urban centres.

“…The availability of productive agriculture is necessary to keep the growing population fed and to sustain modern civilisation. In most stations situated in Nigeria, there has been an increase in temperature by 0.2–0.3°C per decade (Ibitoye et al , 2017). The yearly difference in recorded harvest is the result of the unusual rainfall and temperature.…”

PurposeAside from oil, the Nigerian economy is largely agrarian, which is rain-fed. Hence the criticality of understanding climate change and its impact on agricultural output is more pressing than ever. This is in line with Sustainable Development Goal 13 which is to take urgent action to combat climate change and its impacts. Regardless, Nigeria has in the past five decades experienced a significant increase in temperature, in the range of 10 to over 30 degree Celsius. Therefore, managing the effect of climate change on agricultural output now has the colouration of a developmental challenge.Design/methodology/approachIn light of this, this study gives due consideration to the impact of climate change on agricultural output between the years 1986 and 2015. For the purpose of analysis, descriptive statistics, unit root test and the ordinary least square (OLS) estimation technique were employed.FindingsFindings from the study reveal that the average annual rainfall, temperature and forest area positively influence agricultural output, whereas drought, floods and agricultural nitrous oxide (N2O) emissions have negative impact on agricultural output. The study suggests the need for a regulatory framework and also an explicit national agricultural policy essential to offset the negative effects of climate change especially on agricultural output.Originality/valueAs Nigeria look to diversify her economy which relied on oil, agriculture is among the alternative sector hoping to drive her economic growth, therefore, it is pertinent to examine the current output in the sector given the effects of climate change.
