Cross-regional differences in water availability, water infrastructure systems, water rights and biodiversity across the Sunbelt of the US provide a compelling platform for understanding the issues in freshwater sustainability under near-term climate change (10-30 years) and population growth. Recent studies suggest that uncertainty in climate change projections are the lowest around 10-30 year time scale, which is a critical planning horizon for developing cross-cutting strategies that ensure freshwater sustainability. The main objective of the proposed research is to understand, identify and quantify uncertainties related to the freshwater sustainability under near-term climate change and population growth by incorporating adaptive responses, feedbacks as well as the needs of hydro-ecological systems and humanenvironmental systems through a cross-regional synthesis. We intend to achieve this by performing retrospective analyses that revisit how better we could have ensured freshwater sustainability in the past 40-50 years across several target basins over the Sunbelt using AR5 near-term climate change hindcasts. Based on the retro-analyses, we scale-up our findings on cross-regional synthesis to develop strategies for future (2010-2040) freshwater sustainability over the entire Sunbelt region of the US.
