Influence of Local Governance on Residents’ Environmental Sanitation Behavior in Nigeria: the Ile-Ife Experience

International Journal of Environmental Problems, 2018, 4(1): 3-18.
DOI: 10.13187/ijep.2018.1.3CrossRef

This paper examined the influence of local governance on residents’ environmental sanitation behavior in Ile-Ife, Nigeria. This was with a view to suggesting policy response in furtherance of a sustainable environmental behavior among residents in the city and others with similar background. Four residential zones were identified in the study area. A total of 2,881 buildings were identified comprising 739, 154, 357 and 431 respectively in the low income, middle income, high income and post crisis residential area. One out of every 10th residential building was sampled in each residential area. A total of 288 residents were selected for survey using systematically sampling technique. The study revealed that residents’ socio-economic characteristics varied significantly across residential areas. The study also found that there is low level of access to environmental sanitation facilities/services in the low income, middle income and post crisis residential areas. The study established that a relationship exist between residents’ environmental sanitation behavior and their place of residence. The study also established a variation in the level of agreement of the functions of the mandated monthly environmental sanitation exercise. In general, the maintenance of dumpsites within the city by government was not satisfactory to the residents across the four identified residential areas. The study recommended a synergy of strategies among environmentally-concerned institutions in the study area in provision of facilities/services, environmental awareness and enforcement of sanitation legislations in the study area.

Biochemical and Antimicrobial Activity of Prosopisafricana

International Journal of Environmental Problems, 2018, 4(1): 19-23.
DOI: 10.13187/ijep.2018.1.19CrossRef

Biochemical properties and antimicrobial activities of Prosopisaricana were examined in the study. Acetone, ethanol and hexane were the solvents used to extract the phytochemicals. Standard methods were utilised in the extraction of these plant chemicals throughout. Alkaloids, tannins, terpinoids, flavanoids, glycosides, steroids and phenols were detected in varying concentrations depending on the solvent used. Zones of inhibition were determined for the three organisms tested for S. aureus, S. typhi and E. coli with the ethanolic extract showing the highest zone of inhibition.

Bioactivity of Crude Extracts of Stem Bark of Vetillariaparadoxa

International Journal of Environmental Problems, 2018, 4(1): 24-28.
DOI: 10.13187/ijep.2018.1.24CrossRef

This research aimed to study the bioactivity of crude extracts of stem bark of Vetillariaparadoxa “Shea-nut tree” as used in traditional medicine for treatment of stomach ache and control of diarrhea, using hexane, acetone and ethanol as the extraction solvents. Phytochemical screening of stem bark of extracts of Vitellariaparadoxa revealed the presence of alkaloids, steroids, phenolic compounds, flavonoids, saponins, tannins, and cardiac glycosides. Ethanol, acetone, and hexane extracts inhibited the growth of pathogenic Escherichia coli, salmonella typhi, and staphilycoccusaureus with varying degrees of activity with the ethanol extract demonstrating the highest activity against all the tested bacterial organisms.

Appraisal of Waste Minimization and Management in the Context of Malaysian Construction Industry

International Journal of Environmental Problems, 2018, 4(1): 29-36.
DOI: 10.13187/ijep.2018.1.29CrossRef

These days, the building and construction industry is a main provider to the source of national economy in most countries. Though, incorrect construction waste management lead to numerous difficulties such as prohibited dumping along the roadsides, demolition waste and disposal of construction at landfills as Malaysia is facing severe deficiency of landfill space and lately the matter has developed more serious through the country, which these have caused major government sources and environmental problem. Sustainable waste management aids construction key players to diminish and making better use of material on their construction project. The waste minimization strategy is not only implemented during the construction stage, but it record and estimates the use materials through whole project delivery process. This paper will discuss and elaborate on waste minimization and management in the context of Malaysian construction sector. Waste minimization plan is necessary to reduce present and future risks to human health and the environment which presents guidelines that can be used by professional personnel and organizations to decrease the amount and perniciousness of wastes generated.

Analysis of Factors Responsible for Poor Urban Environmental Health among Vulnerable Residents of Ondo, Nigeria

International Journal of Environmental Problems, 2018, 4(1): 37-44.
DOI: 10.13187/ijep.2018.1.37CrossRef

Background. This study examines factors responsible for poor environmental health among vulnerable residents of Ondo, Nigeria. This was with a view to suggesting policy response capable of enhancing healthy environment in the city and others with similar background. Materials and Methods. Systematic sampling was used to collect data from a total of 196 households having stratified the study area into the high, medium and low densities residential neighbourhoods. Both descriptive and inferential statistics were utilized. Results. Findings showed that low government intervention was the most important factor responsible for poor urban environmental health in the study area. Results showed that environmental factors are significantly related to health situation of vulnerable people in the study area. Conclusion. The study concluded that poverty tends to breed poor environmental and unhygienic conditions that have great impact on human health. The study therefore suggests some policy guidelines, including redevelopment (in some parts of the study area), upgrading and provision of basic infrastructural amenities and facilities.

Assessment on the Barriers to Application of Lean Principles at the Construction Stage in Bauchi Metropolis

International Journal of Environmental Problems, 2018, 4(1): 56-75.
DOI: 10.13187/ijep.2018.1.56CrossRef

Material waste has been a great nuisance in the construction industry. It is the major cause of the high cost, low value and poor service delivery in the construction industry. The purpose of this study is to provide data that will increase knowledge on waste minimization in construction sites by identifying sources and causes of avoidable waste on construction sites and valuation of level of knowledge of the lean concepts among construction specialists and recognizing obstacles to effective application of the lean concept in construction. Data for the study were obtained through site visitations, interviews and the administration of 1000 questionnaires. Respondents included all the major professionals in the construction industry. Ratios and Simple percentages were used to analyze the data. Data from the analyses indicated about 10 % to 33 % of total construction materials are wasted on site. Results also revealed that method of operation, storage and handling of construction materials, procurement methods, record keeping and design were the major sources of waste on construction sites. It also revealed the presence of some degree in knowledge of lean construction among the construction experts.

Identifying the Challenges Affecting Contractors Performance in the Execution of Building Projects

International Journal of Environmental Problems, 2018, 4(1): 76-82.
DOI: 10.13187/ijep.2018.1.76CrossRef

The aim of this research work is to assess to the challenges affecting contractors in public sector the execution of public sector building projects in Bauchi Local Government of Bauchi State. To identify the challenges facing the execution of projects in Bauchi Local Government through literature review and personal experiences of contractors. To evaluate the extent to which these challenges affect the execution of public building projects in Bauchi. Structured questionnaires were distributed to specialist practitioners and companies. It was discovered that due to the nature of public sector building projects, contractors have a remote relationship with the client. Hence, delay in payments was found to substantially pose a challenge to the contractor when executing public sector building projects. It was also found corruption of government officials to be a great challenge during execution as discovered here. Theft of materials, fluctuation of prices, and poor workmanship were also discovered to generally pose a challenge to the process of executing works.
