An Assessment of Mining Activities Impact on Vegetation in Bukuru Jos Plateau State Nigeria Using Normalized Differential Vegetation Index (NDVI)  [cached]
Musa Haruna D.,Jiya Solomon N.
Journal of Sustainable Development , 2011, DOI: 10.5539/jsd.v4n6p150
Abstract: The study area has a pathetic and deplorable condition of landuse/ landcover. The vegetal cover in the area has to be removed from the activities of tin mining which consequently resulted into adverse environmental effect such as erosion. Different forms of human induced stress such as tin mining and heavy rainfall have severely degraded soils on the Jos Plateau. Such degradation problems are also caused by deforestation, inappropriate farming system, bush burning and over-grazing which are hostile to the environment. The impact of tin mining has greatly affected the natural ecology of the study area Bukuru. Micro and macro organisms and plants have been stripped off their natural habitat due to tin mining activities. This paper therefore, assesses the mining activities impact on the vegetation in Bukuru area of Jos plateau in Nigeria. Normalized Differential Vegetation Index (NDVI) techniques was adopted to Maps effect of tin mining on the vegetation for the period between 1975 and 2007 using LandSat satellite data. The result of the differential vegetation index analysis reveals a decline in vegetated surfaces in 1986 ranging from 0.04 to 0.58 indicating 0.05 and continuous loss in vegetation over the study area in 2007 (vegetated surface decrease by 0.08 between 1986 and 2007). The decrease in vegetated surface is due to intensive mining and cultivation.

Advances in Microbiology (AiM) , 2013, DOI: 10.4236/aim.2013.33043
Abstract:

This study was conducted to investigate the prevalence of haemoparasites of dogs attending ECWA veterinary Clinic, Bukuru, Jos south local government area in Plateau state, Nigeria, and to determine the effective control strategy. From July to September 2011, blood samples of 150 dogs were collected and examined under light microscope. The age, sex and breed of the dogs were also recorded. Wet and unstained blood film shows no motility hence no motile haemoparasite while the Giemsa stained blood smear techniques of both thick and thin film, showed the presence of only Babesia spp in 89 (59.3%), while 61 (40.7%) were negative for any haemoparasite.

Abstract: um glucose level of healthy adolescents within Bukuru metropolis, Jos South Local Government Area, Plateau State, Nigeria Original Research (1768) Total Article Views Authors: Ekwempu AI, Wuyep ZS, Longkem EB Published Date October 2011 Volume 2011:4 Pages 353 - 355 DOI: http://dx.doi.org/10.2147/JMDH.S21867 Adaobi Ifeoma Ekwempu1, Zwalnan S Wuyep2, Bitrus Longkem3 1Department of Medical Laboratory Sciences, University of Jos, Jos, Plateau State, 2Hospital Management Board, Jos, Plateau State, 3Department of Chemical Pathology, Jos University Teaching Hospital, Jos, Plateau State, Nigeria Purpose: This study was designed to determine the blood glucose level of healthy adolescents living in the southern region of Plateau State in northern Nigeria. Design: The study screened apparently healthy adolescents to identify individuals at high risk of developing diabetes mellitus. Methods and materials: Individuals who were confirmed healthy and not on any form of medication were enrolled in the study after the administration of a questionnaire which ruled out any form of aliment such as fever, gastroenteritis, and malaria. The serum glucose level was quantified using the glucose oxidase reagent. Data generated were analyzed using Excel 2007 (Microsoft , Redmond, WA) and Student’s t-test for an established normal range. Results: The age distribution showed that those aged 14–16 years had a mean serum glucose level of 4.8 ± 1.11 mmol/L, while in those aged 17–19 years it was 4.9 ± 1.115 mmol/L, with a standard error of the mean of 0.17 and 0.15, respectively. The mean glucose level, weight, and height of the enrollees were 4.8 ± 1.12 mmol/L, 56.6 ± 6.20 kg, and 1.6 ± 0.009 m, respectively. The mean serum glucose of those from the Berom tribe and other tribes was 4.9 ± 1.21 mmol/L and 4.8 ± 1.15 mmol/L, respectively. Analysis of the mean glucose level with respect to sex, age, tribe, weight, and height of the established normal mean resulted in a P value of < 0.05, which was not significant. Conclusion: There was no significant difference in the serum glucose level of enrolled subjects. It was also observed that there was no significant difference between the glucose level based on the different tribes, sex, weight, and height of all enrolled subjects. Since glucose is involved with various body metabolic processes and is also an analyte of interest in diabetes mellitus, screening of adolescents would reduce the incidence of the disease.

Abstract: A study was carried out to establish the emergence of cutanous myiasis with its zoonotic implication in Vom and Bukuru metropolis of Jos South Local Government Area of Plateau State. 6 individuals (3 males and 3 females) who were suspected to have boils on their skin were diagnosed to be 100% infested with the larvae of Cordylobia anthropophaga. Similarly, in an investigation of dogs, out of 510 dogs examined in Evangelical Church of West Africa and NVRI Veterinary clinics, 47(9.2%) dogs had larvae in their cutanous tissues. Of 300 dogs from ECWA vet clinic 31 (10.3%) were positive, while 16 (7.6%) were positive from 210 dogs screened in NVRI vet clinic. All results were statistically significant at P< 0.05. In comparism, the larvae extracted from human and dogs were all identified to be of Cordylobia anthropophaga. Of 184 Alsatian 13(7.1%) were positive, of 258 Mongrel 27(10.5%) were positive, 3(21.4%) among 14 Doberman were positive and of 54 Rottweiler 4(7.4%) were positive. Out of the 47 positive cases, 31(66.0%) were female while 16 (34%) were males. Among the female positive cases Mongrel showed a prevalence of 18(58.1%). Infestation in July showed a high occurrence of 22(46.8%). Secondary bacterial infection was encountered in two cases of human infestation.

Abstract: Determination of the work index of Gyel-Buruku columbite ore sample in Plateau state, Nigeria, was investigated. The sample of the columbite ore was sourced from Gyel village in Jos East Local Government Area of Plateau state, Nigeria. The “reference ores (granites)” samples were sourced from Jiche and Gurum villages of Plateau state respectively. The reference ores and columbite ore of known weights were ground and pulverized. 80% passing size for the columbite ore, Jiche and Gurum granites samples was obtained at 100 μm sieve size for the feeds and products respectively. The work indexes of reference ores i.e. Jiche and Gurum granites were used to calculate the work index of the Gyel columbite ore sample. The values of 3.42 kWh/ton and 2.72 kWh/ton were obtained respectively for the two different reference granites ores samples used and 3.07 kWh/ton was calculated as their average and determined as the value of the work index of the Gyel-Bukuru columbite ore sample. This work index value obtained for the Gyel-Buruku columbite ore sample lies favourably within the work indexes of 3.94 - 10.81 kWh/ton for columbite minerals sighted in the literatures.

Journal of Sustainable Development , 2012, DOI: 10.5539/jsd.v5n5p90
Abstract: Tin mining activity which was a predominant activity around the Jos Plateau has caused considerable erosion damages to landuse/landcover. Uncontrolled effects through monitored activities do not protect future environmental security. This paper therefore, assesses impact of derived mining activities on landuse/ landcover in Bukuru area in Jos south of Nigeria to determine the extent of degraded mine lands. A time series analysis of Landsat MSS satellite image November 1975, Landsat TM satellite image acquired in 1989, and Landsat ETM acquired October 2005 of the study area were used. Landuse/ landcover were classified from the images using a hybrid manual and spectral based approach. The result shows that out of the 1,574.13sq.km total size of the study area, the degraded area/land, Built-up area, and water bodies increased by 24.58%, 18.51% and 7.57% respectively. Whereas Arable land (farm and grazing land) and forest reserve has decreased by 106.60sq.km (14.16%), and 264.89sq. (35.18%) respectively. It was recommended that comprehensive mitigation studies against these damages should be performed, and regular inspections should be executed to keep these activities of tin mining under control. Modern technologies should be used to obtain more effective results from these studies.

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2009, DOI: 10.4236/jmmce.2009.85032
Abstract: Cassiterite ore was sourced from Dogo-Na-Hawa, in Bukuru, Jos South Local Government of Plateau State, Nigeria. The ore was analyzed as mined and its various constituents noted. Previous study has shown considerable iron ore composition of the deposit. The present study entails the separation and analysis of magnetic mineral (mostly iron ore) from the ore. The beneficiated iron ore was pelletized using the facilities of the Nigerian Metallurgical Development Centre (NMDC), Jos. The pellets so produced were subjected to various tests such as drop resistance, green compressive strength, dry compressive strength at 900℃, tumbler resistance, micro porosity and indurations compressive strength at 1100℃. The results indicated Bukuru cassiterite contains sufficiently high grade of iron ore that could be beneficiated for iron production. The pellets produced are of good quality and could be utilized for iron and steel making.

Abstract: In this paper we present a semi-automatic method to infer groundwater flow-paths based on the extraction of lineaments from digital elevation models. This method is especially adequate in remote and inaccessible areas where in-situ data are scarce. The combined method of linear filtering and object-based classification provides a lineament map with a high degree of accuracy. Subsequently, lineaments are differentiated into geological and morphological lineaments using auxiliary information and finally evaluated in terms of hydro-geological significance. Using the example of the western catchment of the Dead Sea (Israel/Palestine), the orientation and location of the differentiated lineaments are compared to characteristics of known structural features. We demonstrate that a strong correlation between lineaments and structural features exists. Using Euclidean distances between lineaments and wells provides an assessment criterion to evaluate the hydraulic significance of detected lineaments. Based on this analysis, we suggest that the statistical analysis of lineaments allows a delineation of flow-paths and thus significant information on groundwater movements. To validate the flow-paths we compare them to existing results of groundwater models that are based on well data.

Abstract: We describe a semi-automatic method to objectively and reproducibly extract lineaments based on the global one arc-second ASTER GDEM. The combined method of linear filtering and object-based classification ensures a high degree of accuracy resulting in a lineament map. Subsequently lineaments are differentiated into geological and morphological lineaments to assign a probable origin and hence a hydro-geological significance. In the western catchment area of the Dead Sea (Israel) the orientation and location of the differentiated lineaments are compared to characteristics of known structural features. The authors demonstrate that a strong correlation between lineaments and structural features exist, being either influenced by the Syrian Arc paleostress field or the Dead Sea stress field or by both. Subsequently, we analyse the distances between lineaments and wells thereby creating an assessment criterion concerning the hydraulic significance of detected lineaments. Derived from this analysis the authors suggest that the statistic analysis of lineaments allows a delineation of flow-paths and thus significant information for groundwater analysis. We validate the flow-path delineation by comparison with existing groundwater model results based on well data.
