あらすじ・解説
When we think about the use of nature-based features to increase coastal resilience, the focus is mostly on coasts along the ocean. But what about the Great Lakes? Over the past 10 years, the Great Lakes have experienced both historic high and low lake levels. These extreme fluctuations cause flooding, erosion, and property damage, often putting people living in communities at risk. In Season 8, Episode 4, host Sarah Thorne is joined by Burton Suedel, Research Biologist in the Environmental Laboratory at the Engineer Research and Development Center (ERDC), US Army Corps of Engineers (USACE), and David Bucaro, Chief of the Planning Branch, Chicago District, USACE. They are discussing the important work underway to make the Great Lakes more resilient to the effects of climate change.
The Great Lakes play a critical role in the heart of North America and are being affected by climate change, including rapidly changing water levels and less ice coverage. There is a complex interaction between the lakes, land, and atmosphere that make it difficult to model the system. As David notes, this creates high levels of uncertainty in long-term projections of lake levels and challenges for making informed, resilient, and adaptable decisions about needed long-term investments.
To help better prepare for these future conditions, David and his colleagues are working with other federal agencies, Tribal nations, state and local governments and academic partners, to identify the full range of Great Lakes water levels, wave heights, and ice conditions under a range of plausible climate change scenarios. This is the focus of the 6-year, $14M Great Lakes Coastal Resilience Study (GLCRS), a regional partnership to create a strategy that identifies vulnerable coastal areas and offers an array of potential actions that can be taken to bolster the built natural coastal environments.
The first step was the development of a shared vision and a basin-wide assessment of vulnerabilities looking at existing populations, infrastructure, habitat, land use, and socially vulnerable populations across all of the Great Lakes coasts. This effort will help communities better understand the frequency and impacts of various climate scenarios and will provide detailed information for planners and engineers, including an assessment of “hotspot areas” more vulnerable to future conditions. The next step will be to identify specific actions for the hotspot areas, which may include a combination of monitoring and further study. The final step will be to produce the Great Lakes Coastal Resiliency Plan, which will include strategic recommendations and prioritize actions for USACE, other federal agencies, states, locals, and other nonfederal interests.
This effort is complemented by the work that Burton and his team are doing on The Great Lakes Natural and Nature-Based Features Playbook, which is intended to develop new conceptual nature-based designs specific to the Great Lakes that will achieve greater resiliency and adaptability to climate change. The Playbook is intended to be used by planners and NBS practitioners within and outside of USACE to support the planning-level cost-benefit analyses. David and Burton hope the Great Lakes Coastal Resiliency Plan and the EWN Playbook will benefit other regions and advance the practice of NBS.
