An Application of Contingent Valuation Method for Reduction in Risk of Premature Mortality due to Air Pollution: A Case Study of Gujranwala, Pakistan
Abstract
In contemporary Anthropocene Epoch air pollution (AP) has crossed the environmental safety standards in most of the urban areas of Pakistan and resulting serious threats to human health. Gujranwala, one of the major cities of Pakistan, also faced many adverse health consequences in terms of respiratory and cardiac diseases, which resulted premature mortality. Contingent Valuation Method (CVM) opted to find trade-off between income and risk of premature mortality. Stratified Random Sampling technique followed to survey 174 respondents in total. Logistic regression was followed for estimation by taking WTP as dependent variable and it was estimated that household’s monthly income, health cost, air pollution effects health or not, air pollution result premature mortality or not had significant impact on WTP, while education and employment nature had insignificant impact. The monetary values estimated against each risk reduction option were as follows; PKR 387286 for 1-in1000, PKR 664000 for 5-in-1000 and PKR 931000 for 10-in-1000. A diminishing trend had been observed in trade-off among marginal resources forgone and minimization of risk associated to additional life.
