Implementing a trans-boundary flood risk management plan: a method for determining willingness to cooperate and case study for the Scheldt estuary
Zagonari, F. (2013). Implementing a trans-boundary flood risk management plan: a method for determining willingness to cooperate and case study for the Scheldt estuary. Nat. Hazards 66(2): 1101-1133. https://dx.doi.org/10.1007/s11069-012-0538-1
In this paper, I applied statistical, econometric, and mathematical methodologies to evaluate the conditions required for implementing a publicly supported trans-boundary flood risk management plan in accordance with the EU Floods Directive (2007/60/EU). Although this paper adopts a focus on the methodology rather than on solving a specific problem, the Scheldt estuary is used to provide an illustrative case study of this approach. I showed that, apart from some expected minor differences, the Belgians and the Dutch can be considered a relatively homogeneous population. Moreover, I estimated the main determinants of both perceived flood risk (PFR) and willingness to pay (WTP) for a compensation fund by using a linear model and an ordered probit model (based on a double-bounded dichotomous-choice approach), respectively. Some policies appear to be potentially effective: a campaign to inform the general public about evacuation and trauma management could increase WTP by 19 and 21 %, respectively; an information campaign focused on young women could reduce PFR; and a campaign to inform the general public about flood strategies and the need to disregard flood events in the press could reduce PFR by 56 and 54 %, respectively. Finally, I showed that, apart from some expected differences between the values at risk in Belgium and the Netherlands, both individual rationality and overall feasibility conditions are met. Thus, if information campaigns and other measures are designed to account for differences between the Belgians and the Dutch, a publicly supported trans-boundary flood risk management plan can be successfully implemented.
