Willingness to pay of households for the solid waste management (SWM) improvement in Tu Ky Town, Hai Duong City, Vietnam
Thesis Abstract:
Solid waste management remains a major environmental concern among many countries in Southeast Asia particularly Vietnam. Given the current pressure of industrialization, urbanization, and increasing population in Tu Ky Town in Hai Duong City, Vietnam, this study was conducted to determine the willingness to pay of the households for the improvement of the its solid waste management system. A total of 200 households were interviewed using the Contingent Valuation Method (CVM).
An overwhelming total of 195 out of 200 households were found to be willing to pay for the solid waste management system improvement. The computed mean WTP for the improvement of SWM in the Tu Ky town was USD 2.24/hh/m or a total of USD 26.86/hh/year (Logit model) and USD 2.95/hh/m or a total of USD 35.67/hh/year (Tobit model). Total benefit amounted to USD 61,714/year (Logit model) or USD 81,952/year (Tobit model) for the entire 2015 population of Tu Ky Town. While the households’WTP was found to be negatively affected by the bid price, their household income and participation in environmental movements (Tobit model) positively affected WTP. This result implied that as bid price increases, the WTP of the households decreases. Income and participation in environmental movements, on the other hand, had positive effects on WTP indicating that high income earning households and high participation in groups or environmental movements would relatively have a higher WTP than otherwise.
