Let’s examine the expected consequences of climate change on water resources in the Pacific Northwest. By mid-century, spring snowmelt in the region is expected to occur three to four weeks earlier and summer streamflow is expected to decline. In the Cascades, measurements of snowpack on April 1 have already declined by as much as 20% since the 1950s. At lower elevations, more precipitation will fall as rain instead of snow which increases flood risks, and reduces snow accumulation and soil moisture, increasing wildfire risk in the following months. Demand for water by the region’s inhabitants is rising and is expected to continue to do so and climate change will exacerbate stresses on water supply. Lower streamflow could also reduce hydropower supply which could cause economic losses in the region. Climate change will also warm the region’s waters which have been noted to increase spring and summer mortality in Chinook and sockeye salmon. All aquatic species will also be impacted by reduced summer flows and increased flooding and winter flows. Finally, these changes to water supply will undoubtedly impact the region’s agriculture and could harm crop yields, as I discussed in a recent article.
This is but one example of the complex challenges and considerations potentially faced by our social, environmental and technological systems (which are interconnected, and collectively called SETs) in the Pacific Northwest and more broadly across the globe. The myriad, complicated challenges faced by SETs will require adept responses — and in some cases transformation — for successful adaptation. Traditionally, our municipal, state, or even federal government have addressed the negative impacts of interaction between society and environment largely through bureaucratic management and regulation. However, in a recent study, University Distinguished Professor Emerita Barbara Cosens from the University of Idaho and her fellow researchers from across the United States and the European Union (brought together by the NSF funded National Socio-Environmental Synthesis Center, SESYNC) posit that these traditional forms of government lack the flexibility and adaptability to quickly respond to the fast-paced and dynamic issues that we are facing today. Instead, the authors discuss the need for adaptive governance—a form of governance that involves self-organization of both the private and public sectors and formal and informal institutions that can fill roles in addressing the challenges SETs face. Within an adaptive governance framework, actors such as non-profits, community groups, and private stakeholders (e.g. businesses, concerned citizens) could interact with local and regional governments to engage in solution-oriented responses to environmental and social change.
