InNewZealand,acombinationofseriousgaminganddevelopmentofadaptation
pathwayswere used in a local government flood riskmanagement decision-setting
(Box12.5;LawrenceandHaasnoot2017)(ongamingseealsothechapterbyMech-
ler et al. 2018b). The Sustainable Delta Game (Valkering et al. 2012; http://delta

and climate change uncertainty (Van Pelt et al. 2014). The aimof the exercise on
the Dynamic Adaptive Pathways Planning (DAPP) approach was to upgrade the
existingflooddefencesystemto1in440yearsandmaintain that level (‘levelofser-
