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.
Climate Change Implications for Agricultural Sustainability in Enugu in the Guinea Savanna Eco-Climatic Zone of Southeastern Nigeria: Input from Climate Change Proxies (Published)
Climate change poses debilitating effects for agriculture and food security in low technology countries such as sub-Saharan Africa. The trends and variations of some climatic variables that influence agriculture were analysed using integrated statistical techniques. The aim is to examine the possible effects of climate change on agricultural sustainability in Enugu, southeastern Nigeria using lessons drawn from trend analysis of historical time series of meteorological variables in monthly time step in the area. The area whose economy is largely agrigarian has continued to witness incidence of poor crop productivity. Significant long-term trends were identified in some of the variables and non-significant trends in others. Inferences were made with considerable support of evidence and high degree of confidence. The climate of the area is changing in a manner that concern for agricultural sustainability is on the front burner of the long-term resulting consequences. The need for pre-season and on-season climate information dissemination system is advocated to provide timely and accurate agro-meteorological information
Personality Traits as Predictors of Organizational Commitment among Public and Private Sector Employees in Enugu, Nigeria (Published)
This study investigated five personality dimensions – openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism as predictors of organisational commitment among selected employees in Enugu. Using convenience sampling technique, 200 employees were selected from four public and private sector employees in Enugu metropolis. The participants comprised of 115 males and 85 females with ages ranging from 22 – 50 years and a mean age of 36.00 years. Participants were administered with the Big Five Personality Inventory by John and Srivastava (1999) and the Organisational Commitment Scale by Buchanan (1974). Five hypotheses were postulated and tested using cross sectional survey design and multiple regression analyses. Result showed that only openness to experience significantly predicted employees’ organisational commitment. Conscientiousness, extraversion, agreeableness and neuroticism were not significant predictors of employees’ organisational commitment. Based on the findings, it is recommended that employers apply personality tests in assessing potential employees.
