Abstract: Linking
tropical cyclone activity with anthropogenic climate change is subject
to on-going debate. However, modelling studies consistently have
projected that climate change is likely to increase the intensity of
cyclones and the related rainfall rates in the future. A precautionary
approach to this possibility is to adapt to the adverse effects of the
changing climate by improving early warning services for cyclones as a
‘no or low-regrets’ option. Given limited funding resources, assessments
of economic efficiency will be necessary, and values for benefits are
an essential input. This paper aims to estimate the benefits to
households of an improved cyclone warning service in Vietnam. Choice
experiment surveys with 1,014 respondents were designed and conducted to
inform this paper. The benefit estimates of the maximal improvements in a
number of attributes of cyclone warning services (i.e. forecasting
accuracy, frequency of update, and mobile phone based warnings) are
approximately USD7.1–8.1 per household, which would be an upper bound
estimate. Results from the marginal willingness to pay for the
attributes suggest that investments should be dedicated to improvements
in the accuracy of warning information and a warning service based on
mobile phone short message.
Highlights
►
Willingness to pay for improvements in tropical cyclone warning
services in Vietnam was estimated.
► Choice experiment surveys with 1014 respondents were designed and conducted.
► The willingness to pay for maximal improvement program is about USD7.1–8.1 per household.
► Investments in cyclone warning services should be directed towards improvements in accuracy and mobile phone based warnings.
