Resilient communities have the strength to withstand, respond to, and adapt more readily to acute shocks (such as flooding from extreme precipitation) and chronic stresses (such as ongoing effects of the changing climate on the local tourist economy). The urban heat island effect may worsen chronic stresses.
Minnesota already is experiencing changes to its highly variable climate with shorter winters, fewer cold extremes, andmore heavy and extreme precipitation resulting in repeated freeze-thaw cycles, a longer growing season, and new invasive species. Based on climate modeling, it is expected that in the future Minnesota additionally will face heat extremes and drought, with diminished air quality from increased wildfire smoke, higher levels of ozone, more pollen, etc. Implementing best practice actions to plan and prepare for such events and trends will strengthen cities for greater resilience to the changing climate.
On October 16, 2015, Governor Dayton signed the Under 2 MOU, a global compact among cities, states and regions worldwide to limit the increase in global average temperature to below 2 degrees Celsius (3.6 degrees Fahrenheit). This Global Climate Leadership Memorandum of Understanding recommits Minnesota to limit the impact of climate change and to collaborate on actions that promote adaptation and resilience. Signatories will share green infrastructure solutions and innovative practices for financing and supporting climate adaptation.
The Minnesota Pollution Control Agency strategic plan for 2018-2022 includes the cross-agency goal: Act on opportunities to increase resilience of communities and the environment to climate change impacts.
Sustainability and Resilience are different lenses that overlap. Sustainable communities strive to achieve economic stability, environmental health, and social wellbeing for all without compromising opportunities for future generations to enjoy the same. Resilient communities understand that impacts of climate change are occurring now. Resilient communities prepare for, adapt to, and thrive in the face of abrupt and unforeseen weather, social, and economic changes, while increasing the use of clean energy sources and enhancing local infrastructure to limit risk and accelerate recovery from disaster, now and into the future. Many sustainability best practices are also resilience best practices, providing co-benefits to reduce risk, enhance public amenities, decrease GHG emissions, strengthen air and water quality, and more.

Delivering Urban Resilience, a 2018 report from the clean energy advisory and venture capital firm Capital E, crunches the numbers on three cities (Washington, D.C., Philadelphia, El Paso) and concludes that investing in city-wide adoption of cool roofs, green roofs, solar PV, reflective pavements, and urban trees could deliver roughly half a trillion dollars in net financial benefits nationally.
According to the Natural Hazard Mitigation Saves: 2019 Report (National Institute of Building Sciences), exceeding code requirements for new-building construction to protect against riverine flood has a benefit cost ratio of 5:1.
