Republic of Peru Robust Decision-Making in the Water Sector

Abstract

This study draws upon state-of-the-art methods for decision making under deep uncertainty (DMU) to give SEDAPAL and decision makers in Lima answers to pressing questions. It draws upon several methodologies including Robust Decision Making, Decision Scaling, and Adaptive Pathways, to prioritize the investments in SEDAPAL’s Master Plan. Together these methods help define an investment strategy that is robust, ensuring water reliability across as wide a range of future conditions as possible while also being economically efficient.
