Abstract :

Solid waste disposal has been a serious problem in most developing countries, including Nigeria. For a suitable dumpsite to be identified and selected, it requires the adoption of careful and systematic procedures. Thus, this study looked at the application of geospatial technique in selection of suitable solid waste dumpsite in Aba, Abia State, Nigeria. The integration of GIS and MCDA provides a reliable platform for solving the site selection problem. The study relied on the existing spatial data of the study area such as land use maps, cadastral maps, and satellite imagery maps. The coordinates of the existing solid waste dumpsites were collected through field measurements. The digitized datasets were interpolated with Arc GIS (Software) to generate operation of different dataset layers. The spatial analysis were carried out to identify potential sites. A final composite map was then produced, which presents all areas suitable for waste land filling. The study revealed that, of the 27 dumpsites, 26 were not properly located while the only dumpsite is grossly inadequate for the quantum of waste generated in Aba. Secondly, the study revealed lack of management presence at the dumpsite. Furthermore, the study revealed that the government policy on ground is not effective enough to curb the indiscriminate disposal of these solid wastes in the study area. The study strongly recommend for additional dumpsites to be established in the area, especially areas identified as most suitable amongst others. The study concludes that if the recommendations are strictly implemented, solid waste would be collected and disposed-off in an effective and environmentally safe manners.
