Dynamic Adaptive Policy Pathways (DAPP) and the Pathways Generator (PG)​

The Dynamic Adaptive Policy Pathways (DAPP) framework supports the development of adaptive planning strategies over time, for uncertain future conditions. The Pathways Generator (PG) develops pathways maps to define the solution space and allow comparison of alternative pathways into the future, via evaluations of costs, benefits and co-benefits. Together, DAPP and the PG have been used for flood risk in Miami, water supply in San Francisco and coastal flooding in Aveiro, Portugal, among others.   

  • DAPP allows decision makers to consider longer-term implications and path dependency of near-term decisions to avoid investment regret and lock-in as the uncertain future unfolds.
  • DAPP uses ‘tipping points’ based on bottom-up vulnerability assessments and defined with stakeholders to ensure that system performance is maintained under a variety of futures.
  • DAPP and the PG can be used with different levels of analysis from qualitative expert judgement to quantitative modelling results
