HOUSEHOLDS’ PREFERENCES AND WILLINGNESS TO PAY FOR SOLID WASTE COLLECTION SERVICES IMPROVEMENT IN KANO METROPOLIS, NORTH-WESTERN, NIGERIA

Abstract

This study employed a choice experiment (CE) technique to estimate the households’ willingness to pay (WTP) for improved solid waste collection services (SWC) in Kano metropolis, Nigeria. A multinomial logit (MNL) model was developed for deriving the households’ preferences of SWC service attributes and their marginal value on the non-market values among households. The trade-off between five different SWC service attributes revealed that improvement in waste collection frequency (CF) is the most preferred service attribute. The total value for SWC services is estimated at ₦3341 76935.44 ($1696329.6215). This indicates households are willing to pay for improved SWC services to ensure environmental sustainability. Our results reported here have imperative policy implications for effective SWC services in minimising environmental degradation via pollution and to safeguards public health against filthy environmentally related public health threats.
