The Scenario Focus Group (SFG) is comprised of water policy and planning decision makers at the national and international level who collaborate within the Water Futures and Solutions Initiative, primarily by identifying key water management challenges, priorities, trends, options, and trade-offs within their regions and advising on where further systems analysis and investigation would be most helpful for understanding externalities and guiding planning decisions. The SFG guides the development of relevant and plausible scenarios across which the sustainability and robustness of potential solution options can be tested.
