Globalization And Governance: Impact On Environmental Sustainability In Nigeria’S Niger-Delta Region, Fanan Ujoh Ph.D, Olarewaju Oluseyi Ifatimehin Ph.D

Dr. Fanan Ujoh

With the discovery of oil in commercial quantities in 1958 in the Niger-Delta region came intense oil exploration within the region. Consequently, various Multi-National Oil Companies (MNOCs) commenced oil exploitation in the region. Steadily, cases of pollution, resulting from oil spillages, increased as the quantities of oil production increased over time. Almost 50 years of exploration has resulted in widespread environmental degradation in the form of land, surface and ground water pollution. This has affected the region’s livelihood capacity from farming to fishing, which reflects in endemic and systemic poverty among the communities within the region. This study focuses on …

Application Of Remotely-Sensed Data For Modeling Malaria Infection In Lokoja, Nigeria, Fanan Ujoh Ph.D, Olarewaju Oluseyi Ifatimehin Ph.D

Dr. Fanan Ujoh

Aims: To estimate incidences of malaria infection in an urban setting using Remotely sensed data and matching same with hospital records to validate the use of Remote sensing data as a methodology for studying the prevalence of malaria.

Study Design: Analyses of 2006 Nigeriasat-1 and Land sat ETM+satellite data for modeling malaria infection.

Place and Duration of Study: Lokoja, Capital city of Kogi State in Central Nigeria, between March 2012 and January 2013.

Methodology: Extraction of land use types, NDVI and LST maps using ILWIS 3.3 and Idrisi software. Cross tabulation of extracted maps to carry out correlational analyses while …

Appraisal Of Social And Health Impact Of A Cement Plant At Host Communities In Yandev, Nigeria, Fanan Ujoh Ph.D, Frederick Terkuma Ujoh Mr

Dr. Fanan Ujoh

Nigeria has extensive mineral and natural resources hence, developmental projects are being proposed and executed on a daily basis, many of which involve large-scale alteration of human, animal and plant ecosystems. Limestone mining and cement production commenced in 1980 at the study area, Yandev, without an environmental impact assessment 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 appraise the social and health impact that mining of limestone and production of cement has inflicted on the host communities. Descriptive statistics and …

Population Growth And Land Resource Conflicts In Tivland, Nigeria, Fanan Ujoh Ph.D

Dr. Fanan Ujoh

The complex issues of population-resources pressure vis-à-vis communal conflicts in Tivland is the focus of this study. Field interviews and observations were carried out while Census figures for 1953, 1991 and 2006, and Land Use/Land Cover (LU/LC) data of study area for 1987, 1997 and 2007 were used to calculate the Land Consumption Rate (LCR) and Land Absorption Coefficients (LAC). Analysis of Variance (ANOVA) and Post Hoc comparisons using Tukey HSD test were applied. The results reveal that: (i) greatest increase in LCR (0.019) was recorded between 1987 and 1997 while the later period between 1997 and 2007 recorded a …

Modelling Plume Dispersion Pattern From A Point Source Using Spatial Auto-Correlational Analysis, Fanan Ujoh Ph.D, Isa Dlama Kwabe Mr

Dr. Fanan Ujoh

The main objective of the study is to estimate the rate and model the pattern of plume rise from Dangote Cement Plc. A handheld Garmin GPS was employed for collection of coordinates at a single kilometre graduation from the centre of the factory to 10 kilometres. Plume rate was estimated using the Gaussian model while Kriging, using ArcGIS, was adopted for modelling the pattern of plume dispersion over a 10 kilometre radius around the factory. ANOVA test was applied for statistical analysis of the plume coefficients. The results indicate that plume dispersion is generally high with highest values recorded for …

Socio-Environmental Considerations At The Usuma Reservoir In Abuja, Nigeria, Fanan Ujoh Mr, James Ikyernum Mr, Olarewaju O. Ifatimehin Dr

Dr. Fanan Ujoh

Reservoirs are Man’s attempt towards water re-distribution from regions/seasons of abundance/surplus to regions/seasons of scarcity. This study focuses on socio-environmental impacts of the Lower Usuma dam in Abuja, on its four surrounding communities. Stratified random sampling technique was employed in the administration of a questionnaire to 200 respondents. Using descriptive statistics and the student t-test for the analysis, the study discovered that: (i) there has been no significant improvement in infrastructure provision by Government; (ii) cases of water-borne diseases are high; (iii) the communities have lost land for cultivation; and, (iv) the communities believe that the resettlement scheme is not …

An Analysis Of Temperature Variations Using Remote Sensing Approach In Lokoja Area, Fanan Ujoh Mr, Olarewaju O. Ifatimehin Mr, Sunday Ishaya Mr

Dr. Fanan Ujoh

This study investigates the thermal variations of the different land use/cover types in urban Lokoja town retrieved from Landsat TM imagery of 1987. Band 2, 3, 4 and 6 of the imagery were used in the classification, estimation of NDVI, land surface emissivity values, and satellite sensor temperature. The Qin et al’s mono window algorithm was employed to obtain the land surface temperatures of the different land use/cover types classified. The results indicate that there is a significant variation in temperatures among the different land use/cover types in Lokoja. The built up area and the vacant area have the highest …

An Evaluation Of The Effect Of Land Use/Cover Change On The Surface Temperature Of Lokoja Town, Nigeria, Fanan Ujoh Mr, Olarewaju O. Ifatimehin Mr, John Y. Magaji Dr

Dr. Fanan Ujoh

This research integrated remote sensing and Geographic Information Systems (GIS) to identified land use/cover types in Lokoja, including their temporal transformation and association with surface temperatures from the LandSat TM and LandSat ETM imageries of 1987 and 2001 respectively. As the built-up area increased in size (2667.6%) so was the surface temperature (6.48oC), vacant land (872%: 9.65oC), cultivated land (104.4%: 1.2oC) and water bodies (64.3%:0.94oC) while vegetation cover increased by 2.44oC while its area extent decreased (316.7%). These changes were responsible for the rise in the mean surface temperature from 38.39oC in 1987 to 42.61oC in 2001, indicating a 4.22oC …
