A Thesis submitted to the School of Public Administration and Management in Partial Fulfillment for the Requirements of the Award of Degree of Master of Public Administration (MPA) of Mzumbe University, TanzaniaThis research report was about the effectiveness of Solid Waste Management System at Local Government Authorities in Tanzania, the case of Moshi Municipal Council. It specifically describe the solid waste management systems deployed by Moshi Municipal Council and assess the extent to which solid waste management systems enhance the management of solid waste in the Municipality and challenges which impact on the effectiveness of the solid waste management systems in the Municipality. The research approach used is qualitative which was appropriate to the study as it helped the researcher to collect data in the selected wards and process it without the use of any statistical or mathematical operation. The research design used was case study design which enabled the researcher to gather data on relatively large number of people at the same time, for instance during the focus group discussion data were obtained from more than four people in a group. Population of this study includes all people who have the role in overseeing and managing the solid waste management systems in the Municipality and all the selected wards. Data were collected by using both primary and secondary sources. The major findings showed several systems that were used by the Moshi Municipal Council to ensure both effective and efficient Solid Waste Management in the area. For example, formulating of By-Laws, availability of cleanness facilities, wards cleanness competitions as well as provision of incentives to cleaners. The study recommends that, Moshi Municipal Council and the government of Tanzania should prohibit the use and manufacturer of plastic bags because they contribute more in environmental pollution. This will help to reduce the amount of waste collected in both residential and commercial areas as it has been in Kigali Rwanda. The study concluded that solid waste management systems are a major problem in developing countries especially in Tanzania Municipalities. Studies conducted in other areas of the region including Dar es Salaam, Arusha, Mbeya and Mwanza have exposed the problem to be amongst the most urgent concerns which is clearly found to increase with the growing cities of developing nations.. However the Moshi Municipal has proved to be more efficient in dealing with the solid waste management issue than other Municipalities in the country through different systems.
