Towards a sustainable incentive to open defecation eradication

Abstract

This study is aimed at estimating the significant indicators and constructs that directly influence households to recover and reuse faecal waste in Ogun state, Nigeria. Adopting a four-level multi-stage approach, a total of 110, 100, and 120 questionnaires were respectively administered in Ogijo/Likosi, Ilaro I, and Sodeke/ Sale-Ijeun II wards. The selected criteria reflect the variance in the populations of 1,250,435(33%), 1,112,761(30%), and 1,387,944(37%) for Ogun East, Ogun West and Ogun Central, respectively. The pooled confirmatory factor analysis process took the form of several re-estimations, based on the deletion of lowly loading factors and correlation of redundant items, validation of the model, assessment of normality, and full structural model analysis. The structural model established a significant positive relationship between Environmental/Health Factors of Faecal Waste Reusability (EV) and Reusability Factor(RF) (β=0.727, p<0.05), and similarly, Economic Factors of Faecal Waste Reusability (EC)and Reusability Factor (RF) (β=0.715, p<0.05). The study, among all others, recommends a more flexible sanitation business value chain model that is household inclusive and conforms to the paradigm of green and circular economy.
