The threat of the increasing global temperature is now of global concern than ever before. This prompted the authors to gain insights on the Urban Heat Island (UHI) phenomenon in a medium-sized city of Akure, Nigeria. A random sampling of three hundred and twenty-five (325) structured questionnaires was administered and analyzed with the aid of the Statistical Package for Social Sciences (SPSS). Landsat satellite imagery for the years 2000; 2007; 2013 and 2018 were acquired and used for the computation of land use-land cover (LULC) and the Land Surface Temperature (LST) of the study area using ArcGIS 10.5. Between the years 2000 and 2018, built-up area increased by 8.78% at the expense of the non-built up land use. The residents were aware of UHI and climate change but characterized by superficiality. The study recommends a community awareness program on the menace of climate change and the integration of climate education into the curriculum of schools and other institutions of higher learning.
Urbanization and increase rate of poverty coupled with the challenges of insecurity in most developing countries have led to increase of crime incidence. This phenomenon is not new to residents of Nigeria cities; it has created unrest and great burden. Consequently, this calls for the development of new approaches to tackle crime incidence in cities. This study therefore focuses on the application of Geographic Information Systems (GIS) as a tool for mapping out the area liable to crime in the core area of Akure, Nigeria. The study employs the use of secondary data. Secondary data include: literatures, journals and crime incidence reports gotten from internet, archives and Nigeria Police Force (NPF) respectively. Both spatial and statistical analyses were carried out using the appropriate tools such as Neighbourhood and Correlation Analysis, respectively. This study revealed that the transport route cutting through Akure metropolis is prone to crime activity. Finally, the study recommends that police officials should be trained on how to use GIS to fight crime.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
