摘要
This study aims to develop a risk-based decision support framework for solid waste management practices in Nigeria: with a case study of Bayelsa State. This study used a mixed method approach in its findings; field trips, surveys and observations were carried out as well as the distribution of semi-structured questionnaires. Huge volumes of uncollected co-mingled municipal solid wastes are present throughout the streets, in drains, lakes, rivers and in the countryside. Waste management infrastructures are not available in the state and the few waste collections vehicles available are dilapidated. Appropriate policies, frameworks and models should be adopted; enlightenment campaigns should be carried out as well as adequate provision of waste management facilities and infrastructures. The risk part of the decision support framework was developed while the option appraisal part will be developed at the next stage of the research.
