Household levels of deprivation to wash and residential conditions in slum settlements of Lagos, Nigeria

Abstract

Household levels of deprivation to water, sanitation, and hygiene (WaSH) and residential conditions in slum settlements of Lagos, Nigeria were assessed and mapped using slum deprivation index (SDI). A structured questionnaire was administered to 1,398 households in 16 settlements using a random sampling method. Descriptive statistics and SDI were employed to analyze the data while ArcMap was used to map the patterns of SDI. The results show that households live in poor dwelling conditions with limited access to WaSH facilities. The SDI indicates that 18.7% of the slums are highly deprived. Based on WaSH and dwelling and physical environment (DPE) components, 18.75 and 31.25% of the slums are highly deprived. Water, sanitation, and hygiene indicators show that 37.5, 12.5, and 56.25% of the slums are highly deprived respectively. About 50, 37.5, 43.75, and 31.25% of the slum are highly deprived based on dwelling, waste disposal, waste pile, and stagnant water respectively. The study concluded that six settlements live in deplorable WaSH and DPE conditions. The study recommends urgent intervention for planning and resources allocation, and sustained urban renewal programs at Oko-Baba, Ilaje, Oko-Agbon, Abule-Nla, and Badia for improved WaSH and living conditions for sustainable service delivery and healthy slum settlements.
