Municipal solid waste and flooding in Lagos metropolis, Nigeria: Deconstructing the evil nexus

Abstract

Municipal solid waste (MSW) has contributed significantly to flooding in the Lagos metropolis. This study examined the volume of MSW generated using per capita waste generation, projected population, quantity of MSW collected and deposited at six landfills sites from 2007 to 2013. One thousand and twenty-five copies of a structured questionnaire were administered to obtain data. The points where MSW blocked drainage channels in the metropolis were mapped. Multiple regression was used to establish the association between flooding and MSW at p<0.05. A total of 77,757,749.8 tons of MSW was generated, while 27.7% of it was collected and deposited at six landfill sites from 2007 to 2013. 11% of the municipal solid waste was collected by the Lagos State Waste Management Authority, 9.9% by private sector service providers, 29.2% by cart pushers and 49.7% dumped in canals/lagoons. Weekly collection of MSW was 58.5%. The sampled buildings were flooded at an average of nine times. Two hundred and twenty-two points where MSW blocked drainage channels were identified. The municipal solid waste indicators were statistically significant at F 2, 1022 = 1034.2, R 2 = 0.669. The study recommends measures to enhance the strengths and address the weaknesses of the current approaches towards the attainment of global best practices in the management of MSW and flooding in the Lagos metropolis.

Multi‐scalar interactions between mismanaged plastic waste and urban flooding in an era of climate change and rapid urbanization

“…Special attention has been paid to the effects of plastic bags of drinking water, which have been suggested as a cause of floods when empty bags accumulate in gutters and drains (Stoler, 2017). For example, in Lagos, Nigeria during the rainy season researchers documented 222 storm drains across the city where localized flooding could be attributed to accumulation of plastic waste (Ojolowo & Wahab, 2017). UN Habitat relatedly collected a series of city case studies documenting the impact of improperly managed solid waste in channels and drains on flooding in several countries in Africa, Asia, and Latin America (Espinosa, 2000; Gupta, 2007; UN Habitat, 2010).…”

An extended TPB model of waste-sorting intention: a case study of Indonesia

“…Mismanage waste is detrimental to our environment and all living things. Problems such as pollution (Ferronato and Torretta, 2019), diseases (Boubellouta and Kusch-Brandt, 2021), floods (Ojolowo and Wahab, 2017) and wildfires (Lestari et al , 2022) might result from mismanaged waste. Indonesia was recorded as one of the biggest waste contributors (Priliantini et al , 2020; Yusuf, 2019).…”
