The study was carried out at the Federal University of Technology Owerri, where ongoing and completed projects in the institution were assessed. The study is a descriptive survey employed questionnaires, interviews, and documentary records as a research instrument. The sample size comprised of 50 procurement professional and public projects experts in various selected units in the institution as respondents. The research objectives were analyzed using descriptive statistics of frequency as a tool that was computed using Microsoft Excel and presented in the form of charts and histograms. Qualitative data collected from interviews with respondents were recorded by using tape recorders and then transcribed. The outcome of the study reveals that the current tendering process in Nigeria has vulnerabilities that can be exploited to negatively impact public project delivery. The study...

Using Landsat imagery, this study assessed land cover and LST changes from 1984 to 2019. Land cover was extracted, LST was determined from Landsat imageries and the land cover changes were linked to LST using the contribution index (CI). Afterwards, the universal thermal climate index (UTCI) was calculated to determine the heat stress levels. Findings confirm the presence of urban sprawl and new growth areas in previously rural Local Government Areas (LGAs) eastward, northward and westward of Lagos metropolis and in regions which lie on the fringe of the state's border with Ogun State. Also, a very strong link between high LST intensities and increasing concentration of urban areas in rapidly growing LGAs has been observed. This...
