SUMMARY:

Many urban water supply systems (UWSS) are already facing scenarios marked by accelerated and unpredictable changes. Extreme climate events, unexpected land use changes, water sources pollution growth and increase in water demand are some of the challenges faced today by decision makers. Some of these conditions are aggravated by Deep Uncertainties (DU), defined as conditions characterized by lack agreement from analysts about its main attributes, probability distributions, and its impacts on system performance. Recently, decision support tools evolved to include adaptive approaches and methodologies termed as Decision Making Under Deep Uncertainty (DMDU) incorporating DUs in the analysis. Despite having successful and robust applications around the world, in Brazil DMDU approaches have not been extensively explored, even though many national contexts would justify its application. The UWSS in the Federal District (FD) operates in a region marked by rapid and persistent population growth, fast land use changes and accentuated disparities in socioeconomic conditions and infrastructure access. This work proposes the application of the Deeply Uncertain Pathways framework, to build and assess planning and management portfolios for the FD UWSS that couples long term infrastructure measures and drought mitigation actions using the WaterPaths software. Results show strong tradeoffs between system reliability and the use of water consumption restriction measures, and also a strong need of infrastructure investments to maintain water supply sustainability, especially in the short term. The local socioeconomic disparities in robustness and in policy performance are also key results, showing that historic socioeconomic inequities can exacerbate water crisis impacts, specially to the most vulnerable populations.
