This policy brief by the Climate and Development Knowledge Network outlines a framework for integrating climate resilience into water security investments. It advocates for Robust Decision Making (RDM) to manage the high level of uncertainty regarding climate impacts on specific regions and sectors, prioritizing 'no/low regret' investments that provide benefits regardless of the climate scenario that materializes.

This policy brief, produced as part of the European Commission FP7 funded MEDIATION project, evaluates Robust Decision Making (RDM) as a decision support tool for climate change adaptation. RDM focuses on identifying strategies that perform well across a wide range of plausible futures—prioritizing 'robustness' over 'optimality'—particularly in situations of 'deep uncertainty' where probabilistic data is scarce.
