Impact of improper municipal solid waste management on fostering One Health approach in Ethiopia — challenges and opportunities: A systematic review

Improper disposal of solid waste, predominantly illegal dumping, can lead to severe air and water pollution, land degradation, climate change, and health hazards due to the persistence of hazardous materials. As a result, it is threatening public and animal health, environmental sustainability, and economic development. The One Health approach, which acknowledges the interconnectedness of human, animal, and environmental health, offers a comprehensive solution. This systematic review examines the impact of improper municipal solid waste on fostering One Health approaches at the national level of Ethiopia by identifying key challenges and opportunities. Publications were retrieved from peer-reviewed, indexed journal publications, government documents (policies, proclamations, regulations, and guidelines), and credible non-governmental organization publications from selected electronic databases (Google scholar, PubMed, EMBASE, Global Health, Web of Science, etc.), and governmental offices. Despite efforts to advance the One Health approach in Ethiopia through the formation of the National One Health Steering Committee and technical working groups, implementation is hindered by challenges such as poor sectoral integration, insufficient advocacy, financial constraints, and limited research. These challenges contribute to worsening zoonotic and infectious diseases and environmental issues due to inadequate solid waste management. Nonetheless, opportunities exist through One Health integration via holistic programs, interdisciplinary collaboration, community engagement, policy enhancement, institutional capacity building, and public-private partnerships. Therefore, enhancing sectoral integration and increasing advocacy efforts and securing financial support is necessary to back waste management initiatives and related research. Further research is crucial to understand the impact of solid waste management and the potential benefits of the One Health approach in Ethiopia.
