Water systems across the Northwest sustain crops, livestock, ecosystems, people and power production. These highly managed, interconnected networks of rivers, reservoirs, canals, and pipelines are economic mainstays for the region, and play a foundational role in food and energy security and sustaining natural resource livelihoods.
However, climate change has begun to challenge water resources by increasing temperatures, decreasing snowpack, and altering the timing and amount of available water (Regonda et al. 2005). Current water management systems are designed around historical norms and trends that are rapidly becoming outdated, due to increasing climate variability and uncertainty about future resources. As a region, we now have to reconsider how best to plan around and adapt to expected change in order to reduce and avoid negative consequences to the overall food-energy-water system and to community well-being. But where is such adaptation planning particularly urgent? We synthesized data from across the Northwest to answer this question. Continue reading
