In the face of high-impact, but uncertain, environmental changes likely to affect the supply and demand of water resources, societies are discussing the need to adapt to such changes and considering their available options to do so. Inspired by a decision-analysis approach called robust decision making (RDM), a collaborative science-policy dialogue is being sustained in Chile's Maipo River basin. The Maipo is a highly populated, water-scarce basin that has long faced multiple environmental challenges.

This work would not have been possible without the generous primary support of the International Development Research Center (IDRC) of Canada, under grant 107081-001. We also acknowledge partial support from the International Water Security Network, funded by Lloyd's Register Foundation (LRF), a charitable foundation in the United Kingdom helping to protect life and property by supporting engineering-related education, public engagement, and the application of research; and from the Inter-American Institute for Global Change Research (IAI), for Project SGP-CRA005, which is supported by U.S. National Science Foundation (NSF) grant GEO-1138881, and for Research Project CRN3056, which is supported by NSF grant GEO-1128040. The authors are especially indebted to the many regional stakeholders representing all the organizations and entities that participated in the dialogues and events undertaken by this project. Finally, we are grateful for the helpful review and excellent editorial assistance by Robert Merideth of the Udall Center at the University of Arizona.
