| Summary: | Solid waste management (SWM) in Kano metropolis is under the responsibility of
urban authority, known as, Refuse Management and Sanitation Board (REMASAB).
Waste management is a critical issue in the metropolis due to dwindling financial
resources and population escalation. These problems result in poor control and
handling SWM effectively and efficiently, giving rise to adverse threats on both
environmental and public health. In a radical policy response to address this
environmental problem, Kano State government proposed to privatize SWM services,
via REMASAB, for improved collection services, as a better management option to
ensure sustainability in SWM in Kano metropolis.
Thus, the aim of this study is to estimate the economic values and determinants of
waste collection services and their potentials towards effective waste management in
Kano metropolis. Choice Experiment (CE) and Contingent Valuation Methods (CVM)
valuation techniques were employed in the study. In the CVM section, willingness to
pay (WTP) elicitation format, dichotomous choice and a close ended question were
employed. In the CE part, five categories of non-market values of waste collection
services were defined including: collection frequency, storage facilities, disposal
method, pre-collection services and collection value. A total of 400 respondents were
interviewed in face-to-face format, using cluster random sampling method.
In the CVM section, logit model was defined based on dichotomous choice method
for the estimation of the WTP off a specified bid amount to the hypothetical price for
waste collection services. The logit model was used to drive marginal value and
compensating surplus of the respondents to the attributes of non-market values of
waste collection services.The results of mean WTP was estimated using single bounded dichotomous choice
contingent valuation (DC-CVM) format, however, the result demonstrated
respondents positive WTP for improve waste collection services. The estimated mean
WTP was ₦2202.03 ($11.7) per household, and from the CE ₦2593.2 ($13.2) per
household respectively.
.
The households’ statistics acquired from the 2006 Population Census data that Kano
metropolis has a total number of 275,851 households. This implies an aggregate
welfare gain worth ₦607, 432,177.53 ($3, 08,412.06) monthly, or ₦7,
289,186,130.4($33,000,944.82) annually, for the CVM and ₦715, 336813.2 ($3,
631151.3) monthly and annually ₦858,404, 1758, 4 ($43, 573816) for the CE.
Invariably, this study generate significant information on the practical potentials for
improving waste collection services in Kano metropolis.
Generally, the results, in this research indicated that households placed high value on
the collection services, and they are willing to pay for their waste collections in
sustainable manner. These findings can be used for larger societal awareness about
the waste collection services and the incurred benefits, including economic benefits.
The results would also be beneficial to policy makers and PSPs to set priorities to
ensure that the polluters’ pay principal is observed accordingly for environmental
sustainability. |
