Proliferation of household waste irregular dumpsites in Niger Delta region (Nigeria): unsustainable public health monitoring and future restitution

Inadequate collection and improper disposal of municipal waste have a direct negative impact on cities. Disease occurrence in Obio-Akpor (Port Harcourt metropolis, Nigeria) was suspected and linked to the proliferation of dumpsites and proximity to residential households. Evidence showed frequent incidence of diseases outbreak coupled with the topographic coastal nature and the morphological propelling dynamics of sediments transport in the area assisting the situation. The main objective of this study was to assess how the spatial distribution of irregular dumpsites is linked to the disease occurrence (cholera, diarrhoea and malaria) in the community. The data used for the study was obtained through questionnaires administrated at the hospitals, use of GPS for locating disease incidences and waste dumps, interviews and observations. Point pattern analysis using the G-function and the K-function was employed in analyzing the spatial distribution of dumpsites and disease incidences. Correlation tests were performed to test for the relationship between disease incidences and presence of dumpsites. The results showed that there was a significant relationship (p < 0.05) between disease incidences and presence of dumpsites. It was also observed that diseases could occur in areas where dumpsites were not present as cholera and diarrhoea are contagious but malaria is not, though it spreads. The study will be beneficial to governmental agencies, waste managers, institutions, environmentalists, health, social workers and future researchers. © 2021, The Author(s).
