Geographic Information System Model Design for Sustainable Municipal Solid Waste Management: A Case of Migori Municipality, Kenya

Abstract

The purpose of this study was to design and implement a Geographic Information System (GIS) model tailored to address these challenges and achieve sustainable MSWM. The contention of the study is that rapid urbanization and population growth in Migori Municipality have intensified the challenges of municipal solid waste management (MSWM), resulting in inefficiencies in waste collection, disposal, and environmental impact. The study is grounded in Systems Theory, which emphasizes the interdependence of components within a system, the study integrates both technological and environmental factors in its approach. A case study approach was employed, concentrating solely on qualitative data to provide an indepth understanding of MSWM practices in Migori Municipality. The case study method was selected for its ability to explore complex phenomena in a real-world context, offering detailed insights into the challenges and potential solutions for sustainable waste management (Yin, 2018). Data were collected through semi-structured interviews and focus group discussions with key stakeholders, including local authorities, waste management professionals, and IT specialists. Purposive sampling was used to ensure participation from individuals with direct involvement in MSWM, and thematic analysis was conducted to identify recurring themes and challenges. The study findings indicate that the proposed GIS model can optimize solid waste collection routes, improve resource allocation, and minimize environmental degradation. Furthermore, community engagement was identified as crucial for the successful adoption of sustainable MSWM practices. This GIS model provides a tailored, data-driven approach to address the specific needs of Migori Municipality’s waste management system, promoting long-term environmental sustainability.
