Multi-Temporal Change Detection At A Limestone Mining And Cement Production Facility In Central Nigeria, Fanan Ujoh Ph.D, Muhammad Mamman Alhassan Ph.D, Frederick Terkuma Ujoh Mr

Dr. Fanan Ujoh

Limestone mining and cement production at Yandev, Nigeria commenced in 1980 without an environmental impact assessment (EIA) 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 assess the impact that mining of limestone and production of cement has inflicted on the quality and density of vegetation within the study area about 32 years since production commenced. Multi-temporal satellite imageries of the study area (Landsat for 1976, 1986, 1996 and Nigeriasat-1 for 2006), ILWIS Academia 3.3 and SPSS Version 15 were used …

Results: …


Estimating Plume Emission Rate And Dispersion Pattern From A Cement Plant At Yandev, Central Nigeria, Fanan Ujoh Ph.D, Olarewaju Oluseyi Ifatimehin Ph.D, Isa Dlama Kwabe Mr Jan 2014

Estimating Plume Emission Rate And Dispersion Pattern From A Cement Plant At Yandev, Central Nigeria, Fanan Ujoh Ph.D, Olarewaju Oluseyi Ifatimehin Ph.D, Isa Dlama Kwabe Mr

Dr. Fanan Ujoh

Cement production at Yandev, Nigeria commenced in 1980 without an environmental impact assessment to ascertain the extent of damage production activities would bring to bear on the physical conditions of the host environment. This study was carried out to provide baseline data on the rate and pattern of plume rise from the factory. Field survey was employed for primary data collation, while secondary data (climatic and factory data) were acquired from NIMET Makurdi Office and Dangote Cement Plc. Plume rate was estimated using the Gaussian (Mathematical) Model; Kriging, using Arc GIS, was adopted for modelling the pattern of plume dispersion. …


Effect Of Variability In Rainfall Characteristics On Maize Yield In Gboko, Nigeria, Emmanuel Msughter Adamgbe, Fanan Ujoh Ph.D Sep 2013

Effect Of Variability In Rainfall Characteristics On Maize Yield In Gboko, Nigeria, Emmanuel Msughter Adamgbe, Fanan Ujoh Ph.D

Dr. Fanan Ujoh

The study examines the impact of variability in rainfall characteristics on maize yield in a tropical setting. The study design involves the collection and analyses of data on rainfall characteristics and maize yield at Gboko LGA in Benue State, Nigeria. The methodology adopted is the use of archival data on rainfall and maize yield for 30 years, collected from the Agro-Meteorological Unit and Farm Department of Akperan Orshi College of Agriculture, Yandev (AOCAY). The data was analyzed using mean, correlation and regression analysis to establish cause and effect relationship be- tween rainfall characteristics and maize yield at the study area. …


Socio-Environmental Considerations At The Usuma Reservoir In Abuja, Nigeria, Fanan Ujoh Mr, James Ikyernum Mr, Olarewaju O. Ifatimehin Dr Dec 2012

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 Jan 2010

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 Jan 2009

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 …
