Abstract: Solid waste management remains a major environmental and governance challenge for municipalities, particularly in rapidly urbanizing African cities where institutional capacity, infrastructure, and community participation influence the effectiveness of waste service. Rapid urbanization and changing consumption patterns are increasing the quantity and complexity of municipal solid waste generated worldwide, creating growing pressures on collection, treatment, and disposal systems. The city council and local councils in the Bui Division are working relentlessly to improve the urban landscape environment despite their limited resources. This study examines the actual situation of solid waste in the Bui Division and elaborately focuses on solid waste management strategies and mechanisms put in place by authorities to ensure proper disposal and management. This study also examines the efforts deployed by the city council authorities and local actors to ensure an efficient solid waste management system. The methodology adopted in this study to carry out investigations includes both primary and secondary methods of data collection. One method employed in collecting data included field trips to dump sites, within the study area. The results obtained revealed that solid waste management practices such as dumping, landfilling, composting, and to some extent incineration were the most common solid waste management mechanisms practiced in the area. It further revealed that a solid cooperation between the public and private sector in the public-private partnership agreement is implemented through the integrated waste management system. Strengthening collaboration among municipal authorities, communities, private operators, NGOs, and other local actors could improve environmental awareness and public participation in waste management and the dangers of poor solid waste management in the study area.

Abstract: Large quantities of agricultural and agro-processing residues, including coffee husk and pulp, are generated annually in Ethiopia. Southwestern Oromia, particularly Jimma Zone, has abundant biomass resources such as coffee husk, rice husk, sawdust, and other agro-processing residues. However, these resources are often underutilized or burned using inefficient traditional cooking practices, contributing to environmental pollution and household exposure to smoke. This study was conducted to demonstrate and evaluate a household biomass stove under farmers’ conditions in selected districts of Jimma Zone, Oromia Regional State, Ethiopia. The specific objectives were to evaluate the performance of the stove under farmers’ conditions, create awareness about its use for household cooking, and assess farmers’ and other stakeholders’ feedback on the technology. The stove was tested using rice husk and coffee husk as fuels, with 5.5 L of water used for each test. The water temperature reached 96°C after 8.4 min using rice husk and 95°C after 7.7 min using coffee husk. Training was provided to 66 participants, comprising 57 farmers and 9 development agents (DAs), of whom 45 were women and 21 were men. A mini-field day was subsequently conducted with 104 participants, including 73 farmers, 7 DAs, 6 subject matter specialists (SMSs), and 18 other stakeholders. Feedback was collected from 63 respondents concerning the utility, suitability, availability and accessibility, maintainability, and portability of the stove. The majority of respondents expressed positive opinions regarding the technology. The results indicate that the biomass stove has potential for wider promotion in areas where suitable biomass residues are readily available. Scaling up the technology through farmer training, stakeholder linkages, local manufacturing, and improved access to maintenance and spare parts is recommended.
