K.S.D. Siriwardena and L.H.P. Gunaratne*
ABSTRACT
Dengue has become a major environmental health issue
in Sri Lanka. Although many programmes have been implemented, yet a
remarkable success has not been achieved mainly due to lack of
cooperation from the public. In this study, the public choice on dengue
control strategies was studied. The study was conducted in Kandy
Municipality area, which has the highest risk of dengue in the Kandy
district. A choice experiment was carried out with four environmental
management attributes with three levels each. The attributes included
were: improved cleaning, infrastructure provision, motivation of the
public to continue control activities and willingness to pay for dengue
control. A multinomial logit model (MNL) was estimated and the analysis
revealed that people prefer improved cleaning by the neighbours in
surroundings and provision of efficient water supply as effective
strategies for dengue control. Furthermore, motivation strategies,
which included larger spot fines, appeared to be important.
