Determining the Individual Significant Contribution of Public and Private Sector in Housing Delivery in Nigeria (Published)
One of the greatest challenge confronting both rural and urban residents in Nigeria is the need to provide adequate shelter. This study examined the individual significant contribution of the public and private sector in public-private partnerships (PPP) in housing contracts in Ogun State, Nigeria. A field survey was conducted in government ministries (public sector) and some selected professionals (private sector) within the study area. Information gathered from both primary and secondary data was used to determine the significant contribution of the public and private sector in housing delivery. Questionnaires were distributed through systematic sampling method to 58 respondents in both private and public sector participating in PPP housing production in the study area. Result showed that the significant contribution of the public sector in PPP housing provision in Nigeria is the provision of land while the private sector contributes significantly high percentage of finance, manpower and technical support. The study recommended that for successful implementation of PPP housing projects, all tiers of government must strive to complement the weaknesses of the public sector with the strengths of the private sector. Furthermore, since the private sector provides bulk of the finance for PPP housing projects, government should provide a more conducive economic environment to attract more private sector investors.

Sustainable Development Strides in Nigeria: An Analysis of Climate Change Awareness and Environmental Sustainability (Published)
The paper x-rayed the sustainable development strides in Nigeria: An analysis of climate change awareness and environmental sustainability. It started by looking at the sustainable goals as enshrined in the Millennium Development Goals (MDG) and narrowed it down to environmental sustainability. Furthermore, the paper examined man’s destructive interference in the environment; delicate nature of weather and climate with a critical look at the ozone layer. Subsequently, the nature, causes and consequences of climate change were properly reviewed and man’s efforts to create its awareness and how to mitigate the challenges of the change. Finally, the paper stressed the need for environmental sustainability for the future generations through climate change education and the way forward.

SUBSURFACE GEOPHYSICAL MAPPING AND DRILLING OF ABA-ISU LIMESTONE DEPOSIT (SHEET 156E), SOUTH-EASTERN, NIGERIA. (Published)
Geoelectric mapping and drilling of Aba-Isu limestone deposit was carried out using a hybrid method, a combination of Wenner and Schlumberger resistivity techniques. The iso-resistivity maps indicated a roughly NW–SE trending of the limestone deposit. The resistivity values in the range of 40-260Ώm is inferred to be limestone with varying gradations, and relatively low resistivity values <40Ώm. Areas around the central line axis have resistivity values >100Ώm particularly for the “a” of 5m and 10m respectively and consistent and coincidental with the areas where the limestone massively outcropped. The study area indicated a 4-5 layer stratified alternating sequence of high and low resistivity horizons, the sequence start with high resistivity horizon with values >100 Ώm alternating with low-medium resistivity horizons with values in the range of 20-50Ώm. This sequence in 2 or 3 cycles and terminated by the highly conductive horizon with resistivity values of <20Ώms. The pseudo-sections, resistivity values greater 100Ώm are inferred as limestone, there is a consistency of these values on a trend coinciding with the central line axis. The same values are observed at various depths beneath the subsurface implying the occurrences of limestone which extend beyond 35m depth.
