Environmental Quality of Enugu, Nigeria As Impacted by the Primary Air Pollutants in the Area (Published)

Air pollution activities have increased over the years in urban areas of most developing countries like Nigeria. The same has been experienced in Enugu metropolis. This study therefore examined how environmental quality of Enugu metropolis has been impacted by the polluted air in the environment. The metropolis was classified into different neigbourhoods and then stratified into low, medium and high density areas. Samples were randomly collected from these neighborhoods. In determining the residential environmental quality of the area factor analysis (principal component analysis was used to reduce the various environmental quality variables into single factor known as “Y” variable. This served as dependent variable. Primary air pollutants; particular matter, Nitrogen dioxide, sulfur dioxide and carbon monoxide constituted the independent variables as x1, x2, x3 and x4 respectively. Using multiple regression model a relationship between the dependent and independent variable was established. The coefficient of determination in the result showed that adjusted r2=.917, indicating that 91.7% variation in the   residential environmental quality could be predicted from air pollution. Health challenges of reduced oxygen carrying capacity of blood, chronic bronchitis and worsening respiratory illnesses were identified as some of the effects. Also identified, are acidification of soils, staining of fabrics among others on the environment. Making petroleum products like kerosene available and affordable to all by the federal government of Nigeria, among others have been recommended.

Effect of Cassava Mill Effluent on Microbial Properties of Garden Soil: Eziobodo Imo State Nigeria (Published)

An assessment of the Effect of Cassava Effluent on Garden Soil was made. Two soil samples were collected; one from a farmland polluted with cassava effluent and, another as an unpolluted sample – free from cassava effluent pollution. The microbial analyses were carried out to investigate the effects of the cassava effluent on the soil microbial qualities of garden soil. Results showed that unpolluted soil sample was normal, while the results of the polluted soil sample showed extinct or absence of normal garden soil microbial fauna with the presence of Staphylococcus aureus which are more harmful than good wherever they are found. However, the presumptive identification of fungi in the polluted soil sample showed presence of Candida sp. The results of the bacteriological count showed absence of coliform bacteria, and the Triple sugar iron and various biochemical reactions showed the absence of bacteria such as Bacillus sp which possess nitrogenise and is able to fix atmospheric nitrogen. Such genus of bacteria could stimulate plant growth by colonizing plant tissues – external or internal and providing fixed nitrogen to the host plant. Also various species of Bacillus have the ability to increase plant nutrients in soil. Bacillus forms positive interactions (symbiotic) involving bacteria and fungi to stimulate growth in plants. Many strains are capable of inhibiting pathogenic growth or activity directly and indirectly in soil.Enlightenment campaign, detoxifying cassava effluent in accordance with regulatory Standard, appropriate method(s) of environmental friendly disposal of both solid and cassava wastewater are recommended for safe and healthy environment.

Emerging Issues of Green Logistics in Manufacturing Firms of China: A Literature Review (Published)

With the world’s largest population and increased rate of growth, China’s economy is faced with a big concern of moving towards more sustainable development initiatives. This paper aimed to evaluate the emerging issues of green logistics in Chinese manufacturing firms. This research used content analysis to review literature from recent journals, magazines and newspapers to draw out secondary data that helped to analyse the drivers of green logistics practices and the challenges faced by Chinese manufacturing firms in implementing them. Material collection, descriptive analysis, category selection and material evaluation steps were used when conducting the analysis. The emerging issues of green logistics in Chinese manufacturing firms were found to be driven by regulatory measures, pressures arising from customers and competitors, and social cultural responsibility. Key barriers to green logistics implementation by these firms were associated with technical factors, organization factors, and financial and human resource constraints. A great deal of potential for green logistics studies is present in China and a proper research funding and infrastructure will aid in the sustainability agenda of this economy. For the Chinese manufacturing companies to cope up with the environmental crises, they need to consider environmental protection issues and integrate these with their operational decisions to create sustainability in their organizations. More co-operations in these firms is also needed with better top managerial support to govern employee’s green behaviour and avail technical resources and learning capabilities within the industry. Although few researchers have studied Green Supply Chain Management in China, this paper is unique in that it evaluates emerging issues of Green Logistics in Chinese Manufacturing firms using a literature review approach.

Facility Location and Its Impact on the Environment: Using a Centralized and Decentralized Approach, a Case Study (Published)

There has been an increase in consumption of goods in the last century due to the rapid economic growth all over the world. Globalization has availed large streams of goods to meet this demand but the production, transportation, storage and consumption of these goods have caused environmental problems to emerge. Manufacturing companies are facing numerous pressures from the government and consumers to produce environmentally sustainable goods. The decision to set-up a plant is a strategic issue as the best facility location does not only ensure that the costs are minimized but also take care of the impacts on the environment. This paper presents a case of ABC Chinese steel manufacturing company operating in a centralized facility location approach and intends to evaluate the impact of a decentralized approach on the environment. A simulation of the two networks is run and the results reveal that the centralized approach is more suitable for this company as it is not only economical to them but it is also environmentally sustainable due to the lower carbon emissions produced by this model. The research concludes that facility location decisions greatly impacts the environment but the approach to adopt depends on the type of the product, mode of transportation and the choices of fuel.

Impact of Urbanization on Vegetation Cover in Gombe Metropolis and Environs (Published)

Demographic characteristics and economic development are the major determinants of urban shape and pattern of urbanization in Gombe which gave rise to rapid population growth. These determinants resulted to unplanned urban growth, unprecedented urbanization and land use change as a result contributing in the rapid reduction of vegetation cover and loss of arable land in the surrounding urban environment. The aim of this paper is on the impact of urbanization on vegetation cover. Both primary and secondary data was employed in this work. Socio-economic data and information on the status of tree species were gathered through questionnaire survey that involved 195 respondents using purposive sampling techniques in the study area. While the land use land cover analysis was carried out using ArcGis 10.5 and Edras Imagine 9.0. The finding was made to capture as accurate as possible six land use land cover classes as they changed through time. The result of the work shows a rapid decrease on the vegetation and a gradual increase in settlements between 1976 and 2016 due to the fact that Gombe metropolis became the capital of Gombe state in 1996. Also only few tree species were found within the study area, as most trees are cut down for various developmental purposes. The study recommends that urgent attention on conservation of vegetal resources within the metropolis should be encouraged.

Assessment of Built Environment Quality in Ogbomoso, Oyo State, Nigeria (Published)

The interactions between man and environment determine both the quality of environment and as well as the quality of life that man lives. The feedback mechanisms of the interactions between man and environment are directly proportional. The increase in the number of urban dwellers is no more novel as over 50% of the world population resides in urban centers. This continuous and accidental increase in the number of urban dwellers with respect to their actions in the environment has played significant roles in the depletion of the quality of the environment. Since human health or wellbeing depends on the quality of his immediate environment, the focus on environmental quality emerged as a key area for research in urban and regional planning. This paper appraises the quality of the built environment in a steadily urbanizing traditional settlement in Ogbomoso North Local Government, Nigeria using selected environmental quality indicators while necessary recommendations are put forward to rejuvenate sickening built environment.

Analytical Review of Small and Medium Scale Enterprises in Nigeria (Published)

The primary purpose of business is the supply of goods and services to satisfy the societal needs. Wherever people live in conurbations, there is always the need for goods and services. These goods and services are supplied by institutions such as the family, the voluntary organization, the business firms, local, state and federal government. Also, the importance of credit facilities from both the bank and non-bank financial institutions cannot be overemphasized in enhancing the development of SMEs in the country. However, only the effect of initial capital (CAP) and non bank credit facilities (NBK) is significant and responsive towards the enhancement of performance of SMEs while credit facilities from banks are insignificant with respect to SMEs development. Lastly it concluded that government agencies such as the National Directorate of Employment should intensify efforts geared towards training programmes for SMEs.

The Socio-Economic Factors Influencing Honey Production in Uganda (Published)

The study was conducted in Uganda in five districts of Lira, Kole, Nakasongola, Tororo, and Kabarole. A survey was conducted to establish the different socio-economic characteristics of bee-keeping farmers that influence the production of honey. A structured questionnaire was administered randomly to 218 beekeepers from the five districts and data analyzed using STATA 11. The results of STATA indicated four explanatory variables with P-values of <0.05 influencing honey production namely; bee keeping in income generation (P = 0.00, F = 6.6), types of hives kept per farmer (P = 0.00, F= 29.5), total number of hives kept per farmer (P = 0.00, F = 29.7) and number of hives colonized (P = 0.00, F = 13.2). Level of education, gender, age, beekeeping experience, market availability and training of bee keepers were not significant. Our results show that management of number of colonies corresponds to increase in honey production. These findings can support policy makers and beekeepers on honey production increase. We recommend bee keepers to match colony numbers to the resources available in their environment and maintain a minimum of 80 colonised bee hives. The country should promote the use of traditional bee hives and boost their production by making improvements on traditional bee hive construction.

Effects of Industrial Effluent on the Environment Using Allium Cepa and Zea Mays As Bioindicators (Published)

Indiscriminate handling and disposal of industrial effluents into the environment represents one of the major sources of environmental pollution which invariably affects the health of man, plants and animals. The toxic effect of effluent from a candy-producing industry was investigated in terms of root growth inhibition and overall phytotoxicity using bio-indicator plants; Allium cepa and Zea mays. The presence and concentrations of some metals of environmental concern as well as Polycyclic Aromatic Hydrocarbons in the effluent were also determined. The Allium cepa and Zea mays tests were carried out at concentrations of 1, 5,10,25,50 and 100% of the untreated effluent. There was statistical significant (P<0.05) inhibition of root growth in both plants, the shoot length measurement also showed significant difference (P<0.05) at the different concentrations of the effluent as compared with the control. Morphological abnormalities were observed in the roots of the bio-indicator plants, it is therefore recommended that industrial effluents be treated before being disposed into the environment.
