Long-term planning of water resources systems must contend with severe uncertainty in future projections of hydroclimatic variability across multiple scales, as well as uncertainty in human behavior, such as land use and reservoir operation. This talk will review recent developments in adaptive policy design to meet this challenge, centered around the key question: how should we learn from, and react to, dynamic observations of hydroclimatic, human, and ecological variables to ensure long-term sustainability? Specific contributions will cover three areas: (1) adaptation of short-term control rules, enabling existing infrastructure to manage multiple objectives across a range of possible futures; (2) exploration of endogenous system dynamics and feedbacks governing agricultural water demand, an additional source of structural uncertainty in the planning problem; and (3) dynamic adaptation of infrastructure and operations by designing policies conditioned on projected future observations of climate and hydrologic variables. Collectively, these advances provide a foundation to directly map observations and projections of system states and fluxes to adaptive actions for both short-term management and long-term planning. While the studies presented here will focus on the California water resources system, the methods are broadly applicable across agriculture and energy systems facing uncertain climate risks. The talk will conclude with a discussion of future directions and open research questions in the area of adaptive planning.
