Statistical Survey of Waste Management in Osun State, Nigeria: Binary Logistics Approach. (Published)

This research work is in line with the strategic priorities of environment management agencies, and has the potentials to assist the organization in their effort to ensure the efficient management of solid and liquid waste in the City of Osogbo.  With a view of providing empirical data information with respect to the causative factors responsible for the visible environmental pollution by wastes and materials from food outlets. Data was gathered from a representative sample of 332 food outlets on socio-economics demographic, environmental, sanitary and health related variables that are related to waste analysis was performed using statistical procedures such as frequency tables, pearson’s chi-square tests of association and binary logistic regression analysis in the statistical package STATA version 10. Odds rations estimated from logistic regression analysis were used for identifying key factors that affect efficiency in the proper disposal of waste. Results obtained showed that 18% of the 332 food outlets in the study were generally inefficient in waste disposal. Based on odds rations estimated from binary logistic regression analysis, wrong perception (a factor of 10.88), failure to provide trash cans to customers (a factor of 3.15), the operation of food outlets by non-owners of managers (a factor of 2.33), factors that affect the proper management of waste at the 332 food outlets in the study.

An Analysis of Municipal Solid Waste in Lafia, Nasarawa State, Nigeria, West Africa (Published)

Solid waste disposal and management is both an urban and rural challenge; however, this paper focused on municipal solid waste from the perspective of household waste management system in Lafia, Nasarawa State. Questionnaires were randomly distributed to households in eight communities in Lafia metropolis. The quantity and composition of waste generated was determined. The average waste generation per household was found to be 0.65kg/capita/day. The composition shows that 67.6% was made up of biodegradable material while 32.4% were recyclable materials. Lack of adequate waste collection system and proximity to dumpsites were attributed to causing dumping by residents in drains/gutters. Open burning is the major method of treatment discovered by the study. Finally, the paper suggested sustainable environmental education program by the state government to the populace and private sector participation in the disposal and management of solid waste.

Perceived Effect of Waste Generation on the Climate among Rural Households in Oyo State, Nigeria (Published)

This study examined the perceived effect of waste generation on climate change among rural households in Oyo state, Nigeria.  Two local government areas were randomly selected from the three senatorial districts in Oyo state from which five villages each were randomly selected. A total of 15 households across the selected villages were randomly selected to give a total sample size of 150 respondents. Data were collected through the use of interview schedule and analyzed using frequencies and percentages to present the descriptive analysis, while Pearson Product Moment Correlation and Chi- Square were used for inferential analysis. The findings of the study revealed that the average age of the respondents in the study area was  37 years, as majority (75.0%) were married  and had no formal education (63.2%).  Majority (90.0%) were farmers, had small farm size (86.1%) of range 1-5 acres. Kitchen waste (94.7%), crop waste (88.8%) and animal waste (65.3%) were the major waste generated within the households in the study area. Most (92.0%) of the respondents disposed their wastes making use of sacks (83.3%) 62.0% and 74.7% dispose their waste into drainage channels (62.0%) and flowing stream (74.7%) respectively. Few (14.7%) obtained information on waste management practices through the radio. Majority (78.2%) had low knowledge level on waste management practice and wrong perception (79.2%) of the effects of waste generation to climate change. Level of education (2 = 9.273, sources of information on waste management practices (r = 0.325) and knowledge on waste management practices (r = 0.276) have influence on the perceived effect of waste generation to climate change. There is the need to create awareness on the environmental effect of waste and inappropriate waste management practices among rural households.

GREEN PROCUREMENT STRATEGIES AS DETERMINANTS OF FINANCIAL PERFORMANCE: EVIDENCE FROM SMALL AND MEDIUM ENTERPRISES IN UASIN-GISHU COUNTY, KENYA (Published)

Owing to strong influence on economic and social issues, environmental impact attributed by SMEs activities is significant, not only for their magnitude but also in diversity. However SMEs are often unaware of their environmental impact and lack the resources to implement environmental initiatives and since their environmental footprints are small and localized they easily go unnoticed. Nevertheless the cumulative environmental impacts of countless SMEs constitute major environmental challenges to both regulators and stakeholders. Environmental issues is now considered strategic and there has been debate all over the world concerning environmental issues (Green procurement).Many SMEs are reluctant to adopt green procurement strategies until they find financial benefit for themselves. Thus the general objective of the study was to determine if green procurement strategies had an effect on SMEs financial performance. The specific objectives were to determine the extent to which recycling of waste, use of non pollutants, waste management and use of energy saving products determined SMEs financial performance in Eldoret town, Kenya. The study area was Eldoret town, Kenya and the research design adopted was explanatory research design (bivariate analysis) because it compares two variables, the dependent variable being financial performance and independent variable is green procurement strategy. The research used stratified and simple random sampling and Hotels, restaurants, bars and supermarkets were the study units. There are more than 8175 SMEs in Eldoret town and the researcher used stratified sampling and targeted 80 respondents in supermarkets and 197 respondents in hotels/restaurant/bars. Data collection instruments used was five point likert scale questionnaire and structured interview. Data analysis used was descriptive statistics, explanatory factor analysis, Pearson Moment correlation and regression model analysis. Data was presented using tables, figures and in prose form. The study showed that there is a relationship between green procurement strategies adopted by SMEs on their financial performance and it found that most SME’s in Eldoret have an understanding of what green products are, recycling of wastes, what pollution is and what needs to be done to curb pollution and lastly about waste management and the need to use energy saving products to reduce on the cost of energy. From multiple regression tests the study findings; r=0.509 and r2=0.740, which shows that 74% of the growth of financial performance can be explained by the adoption of green procurement. The findings show that the null hypotheses were rejected in each hypothesis and thus there was a relationship. The study recommends that an awareness programme should be organized in schools, offices, through multimedia houses to educate the masses on the need to recycle waste and thus save on their costs and as a way to generate income. The study further recommends that SMEs require greater access to financial services and investment capital. The study will be useful to various stakeholders such as the government, policy makers and purchasing managers who will benefit on knowing that green procurement strategy is an important aspect in any organizations and it can impact environmental and financial performance of SMEs as well as all organizations.

AN EVALUATION OF THE OPERATIONAL EFFICIENCY OF A PUBLIC AGENCY: A CASE STUDY OF ENUGU STATE WASTE MANAGEMENT AUTHORITY (ESWAMA) IN ENUGU CITY, NIGERIA (Published)

Enugu State Waste Management Authority (ESWAMA) is a public agency established in 2004 with the mandate for waste management in the urban areas in Enugu State including Enugu City. After 9 years of existence, it becomes necessary to evaluate its operational efficiency for the purpose of identifying its worth, strength and challenges. For this evaluation, 79 households served as respondents and were purposively selected from the three Local government areas that make up Enugu City. The questionnaire instrument used for data collection contained the 18 statutory functions of ESWAMA and respondents were requested to rate each function as follows; very good (VG), Good (G), Fair (F), Poor (P) and Unknown (U) depending on their perception. Relative Satisfaction Indices (RSIs) were computed for the 79 respondents across the 18 functions in keeping with Likert weighting scale. The results were combined with the outcome of the structured interviews and reasons adduced by the respondents. In accordance with Likert scale, 3 classes of efficiency were established for all the 18 functions. Result showed that ESWAMA scored pass mark in only 22.2% of its functions, and fair mark in another 22.2% and poor grade in 55. 6% of its functions. ESWAMA operational efficiency is therefore found to be very poor, partial and narrow in scope in relation to its entire statutory functions. Responsive leadership with good training, skill and knowledge in environmental sciences and management is recommended to improve its operational level of efficiency.
