Determinants of households’ willingness-to-pay for private solid waste management services in Ibadan, Nigeria

Abstract

The study examined the determinants of willingness-to-pay for private solid waste disposal systems by urban households in Ibadan, Nigeria. A multistage random sampling technique was used to select 552 households for the study. Data obtained from survey were analysed using a logit model-based contingent valuation. Evidence from the logit model indicated that seven variables had significant influence on the households’ willingness-to-pay. Of these, income and asset owned were positive and significant at P < 0.01 but amount of willingness-to-pay and firm services were negative and significant at P < 0.01. Education and occupation were positive and significant at the P < 0.05 level while age was negative and significant at P < 0.10. The implication is that households have certain socio-economic characteristics, which influence their willingness-to-pay for solid waste disposal. The study recommends government intervention in a variety of forms such as encouraging public—private participation in solid waste disposal, an aggressive environmental clean-up campaign, decentralization of Waste Management Boards and privatization of some aspects of waste management to ameliorate solid waste problems and improve health.
