The City of Marquette is the largest city in Michigan's Upper Peninsula and one of the most economically diverse in the state. The city is especially vulnerable to environmental, economic, and social impacts of climate change, largely because it borders Lake Superior. A team of Michigan State University Extension specialists and educators received funding from the Great Lakes Integrated Sciences and Assessments Center (GLISA) to collaborate with GLISA researchers, relevant decision makers, and stakeholders in Marquette to increase community resilience through incorporating climate variability and change adaption strategies into local land use master plans and policies. Key stakeholders in the agriculture, forestry, natural resources, health, planning, and tourism fields participated in the development of climate change concerns and strategies. Overwhelmingly, residents and local leaders wanted to protect the natural environment that makes Marquette such a desirable place to live. This report details the process and results of this community-driven process, and also contains specific, detailed GIS maps of the region that reflect the climate vulnerabilities and concerns of the residents and leaders in the Marquette region.

The Sacramento-San Joaquin River Delta is the grand confluence of California’s waters, the place where the state’s largest rivers merge in a web of channels—and in a maze of controversy. In 2009, seeking an end to decades of conflict over water, the California Legislature established the Delta Stewardship Council with a mandate to resolve long-standing issues. The first step toward that resolution is the Delta Plan—a comprehensive management plan for California’s Sacramento-San Joaquin Delta, developed to guide state and local agencies to help achieve the co-equal goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the delta's ecosystem.
This plan looks at strategies for incorporating climate change resilience throughout New York's entire transportation system.
Coastal areas are especially vulnerable to hazards, now and in the future, posed by waves and surges associated with sea level change and coastal storms. Coastal risk reduction can be achieved through a variety of approaches, including natural or nature-based features (e.g., wetlands and dunes), nonstructural interventions (e.g., policies, building codes, and emergency response such as early warning and evacuation plans), and structural interventions (e.g., seawalls and breakwaters). This report discusses the U.S. Army Corps of Engineers' capabilities to help reduce risks to coastal areas and improve resilience to coastal hazards through an integrated planning approach.
