Public opinion and solid waste in Bangkok

The problems encountered when seeking suitable locations for landfill sites often include public concern over the potential visual, health and environmental impacts. There have been many attempts to predict the response of residents in an area to a proposed landfill site and suggestions of ways to adequately consult and include the local population in the decision-making process. An alternative approach is described in this article where the residents living in the vicinity of a landfill site in Bangkok were asked how much they would be willing to pay for the landfill site to be closed and the waste taken out of the city. The method used, the contingent valuation method, can provide information on how much people value environmental goods and services. The use of the technique in this instance provided an estimate of the costs of the disamenity effects of the landfill site to the local residents.
