Steps to reproduce
1. Download all datasets, questionnaires, GIS coordinate records, and supplementary documents from this repository. 2. Open the dumpsite coordinate dataset in GIS software such as: o ArcGIS Pro or o QGIS 3. Import the latitude and longitude coordinates of the identified dumpsites in Ogbomoso North and South Local Government Areas. 4. Set the coordinate reference system (CRS) to WGS 84. 5. Generate spatial distribution maps showing: o Major dumpsites o Minor dumpsites o Proximity of dumpsites to residential areas o Dumpsites along drainage channels, roadsides, canals, and open spaces. 6. Use the questionnaire responses from Appendix II and Appendix III to perform descriptive statistical analysis using: o IBM SPSS Statistics, R Project, or Microsoft Excel. 7. Compute frequencies, percentages, and cross-tabulations for: o Waste disposal methods o Residents’ perception of environmental quality o Causes of dumpsite proliferation o Environmental and health impacts. 8. Conduct Principal Component Analysis (PCA), KMO, and Bartlett’s Test where applicable to identify major factors promoting dumpsite proliferation. 9. Compare spatial patterns obtained from GIS mapping with residents’ perception data and stakeholder meeting findings. 10. Use the stakeholder meeting minutes provided in Appendix V for qualitative interpretation and triangulation of quantitative findings. 11. Reproduce tables, charts, and thematic maps following the procedures described in the study methodology. All raw data, questionnaires, GIS coordinates, and supplementary materials necessary to reproduce the findings of this study are available in this repository.
