Uncovering public knowledge, attitudes, and practices towards solid waste management: interlinkages, predictive insights, and the role of operational entities in Wah Cantt, Pakistan
摘要
Exploring residents’ perspectives is essential for the social sustainability of Solid Waste Management (SWM) but understudied in developing countries, contributing to ineffective waste management. This study examines residents’ Knowledge, Attitudes, and Practices (KAP) related to SWM services provided by public-private partnership (PPP), public and informal waste management entities (WME). The key objectives included assessment of statistical associations between demographics, existing situation and KAP, and role determination of WME with respect to SWM services and willingness-to-pay (WTP) of residents. The questionnaire survey revealed high knowledge levels (90%) but notably lower attitudes (73.3%) and practices (64.7%). Limited associations were found among KAP with gender, age, education, employment, household income, and homeownership. Residents expressed higher satisfaction with PPP-based services but lower WTP, as PPP operations were funded through revenue from recyclables collected at the material recovery facility. Additionally, residents with higher knowledge scores and served by PPP were 14 times and 3 times more likely to show satisfaction with SWM, respectively. Principal component analysis identified 11 themes, including narrow association of 3Rs with recycling, NIMBY attitudes, reliance on personal behaviours, and low trust in government authorities. These findings provide actionable insights for stakeholders to develop targeted strategies for enhancing SWM in Pakistan. Moreover, parallels can be drawn for other developing countries that share similar socio-economic characteristics to Pakistan.
