dc.description.abstractMany neighbourhoods in Minna have no controlled system of waste disposal. The waste sometimes blocks drainage channels causing flooding and proliferation of insects. This research therefore, aims at analyzing the spatial distribution and perception of the risks of illegal solid waste dumpsites in Minna Town, Nigeria. Global Positioning System (GPS) was used to obtain the coordinates of the major waste dumpsites in the area. Average Nearest Neighbour Analysis was used to determine the pattern of the dumpsites distribution in the area. Buffer of 200metres was constructed to determine the proximity of the illegal dumpsites to residents.The coordinates of each identified dumpsites were overlaid on the imagery covering the study area using the overlay analysis of the GIS. Questionnaire was administered systematically to 384 respondents in the neighbourhoods. Oral interviews and field observations were also carried out.The findings revealed that about 116 illegal dumpsites (100%) were found within the residential buildings and the Z-score value is outside the range of ±1.96 to 1.96 and the p-value is less than 0.05, it showed that the pattern of illegal dumpsites are significantly clustered in nature around the residential area in the neighbourhood. The buffer constructed showed that 77.0% of the dumpsite falls within the buffer zone, while 23.0% fell outside the buffer zone. The findings revealed that all the residents whose houses fell within the buffer zone were victims of diseases, proliferation of insects, air pollution, bad odour and dirty street, while those residents whose houses fell outside the buffer zone are also affected with air pollution, and bad smell from the dumpsites, but mainly when wind is blown in their direction. The result from the perception of the respondents showed that four (Bad odour, proliferation of insects, dirty street and air pollution) out of the nine items of risks posed by the solid waste dumps to the residence are seen to be very serious. The highest score is obtained from bad odour (91%). Proliferation of insects (73%) and dirty street (84) and others are seen to be moderate to the residence in the neighbourhoods. The overall picture is that the people feel that the presence of the solid waste dumpsites in their neighbourhoods has a lot of risks on the residents. The study recommends that dumpsites should be located further than 200 meters from human settlements and should be properly managed so as to minimize its risks on the environment. Neighbourhoods should open dumpsites in remote areas with no residents closer to them to avoid the effect of the dumpsite on the nearby residents and monitor the dumpsite properly. Neighbourhood also have to control the litter and monitor their volume. The neighbourhood need to be educated on the effects of dumpsites on their health this will limit the indiscriminate emergence of dumpsites in the area.en_US
