ABSTRACT
Siting of a solid waste disposal site requires a thorough evaluation in order to locate the best possible area while considering environmental, economic, health and social factors. The dumpsite location of the June 12 market tends to pose risk to health and the environment by emission of noxious gases among others. This study is aimed at developing a multi-criteria analysis for waste management in the June 12 location of the University of Benin. The limitation of this study is that the weight assignment to the different criteria is subjective. The purpose of this research was achieved by means of questionnaire and QGIS software. This study is justified such that the result can help manage solid waste efficiently and thus protect health and the environment from potential risks. The Questionnaire was used for survey as a means of data collection from respondents in order to analyze their views on the existing waste management system at the University of Benin with a confidence level of 90%. The Geographical Information System (GIS) software was used to carry out the multi-criteria analysis of the existing dumpsite and the determination of proposed/suitable sites. From the survey, 282 responses were received and it showed that majority of the sample size said they perceive foul odour when passing the dumpsite route while 86% find it visually offensive. 58.9% believed that the dumpsite is one of the main causes of health issues in nearby hostels while 53.2% are of the opinion that lack of efficient waste management is one of main causes of environmental issues in the school. 90.4% suggested that the dumpsite should be relocated. 43.3% are of the opinion that the best disposal method is recycling. The result obtained from the multiple criteria decision using GIS enable this researcher to locate three possible new locations for the relocation of the dumpsite.
