GUCA: A more granular approach to climate resiliency

Governments and organizations now have a critical new resource developed by a team at the University of Notre Dame: the Global Urban Climate Change Assessment (GUCA). It is a decision-support tool that offers leaders a way to understand and compare city vulnerabilities, assess adaptation plans, and develop resilience.

A more granular approach to climate resiliency

GUCA builds on the foundation of ND-GAIN’s Country Index, which measures climate vulnerability and readiness for over 180 countries. The GUCA pilot provides city-level metrics for 12 cities, incorporating data from multiple sources, including remote sensing. Like ND-GAIN, GUCA is free and open-source, so stakeholders across the public, private, and NGO sectors can identify priorities and direct funding where it is most needed.

GUCA measures vulnerability and resilience across a number of globally comparable metrics. Vulnerability includes specific hazards such as flooding, extreme heat, and landslides. It also measures sensitivity to climate change, which can refer to potential impacts on people (such as children, seniors, migrants, or low-income residents) as well as features of urban areas, such as the rate of urban expansion.

Resilience, on the other hand, is the capacity of a city to withstand shocks and adapt over time. It includes disaster planning, water access, governance systems, and economic stability, recognizing that cities with robust systems can respond more effectively to climate-related challenges.

A tool with global implications

GUCA’s 12-city pilot phase focused on Abuja (Nigeria), Amman (Jordan), Beijing (China), Berlin (Germany), Bogotá (Colombia), Jakarta (Indonesia), Kinshasa (DR Congo), Mogadishu (Somalia), Mumbai (India), Panama City (Panama), Rio de Janeiro (Brazil), and Shenzhen (China). With additional funding, ND-GAIN aims to expand the GUCA framework, enabling a deeper understanding of vulnerabilities and resilience in more cities across the globe.

Wood emphasizes that this expansion is critical because as more people migrate to urban environments, the need to identify and target funding for climate adaptation in the most impacted cities is becoming an even more widespread and urgent concern.

“At the start of the 20th century, only 13% of the world’s population lived in urban areas. By 2050, that number is expected to rise to 60%, with an estimated 4.9 billion people living in cities,” she points out. “Our team at Notre Dame is eager to see the tool evolve with feedback from partners around the world."

GUCA is the latest addition to ND-GAIN’s already robust suite of data-driven climate tools and resources, which includes the U.S. Urban Adaptation Assessment, a tool assessing over 270 U.S. cities’ climate risks and social vulnerabilities by neighborhood.

ND-GAIN is a program of the Notre Dame Environmental Change Initiative (ND-ECI). At ND-ECI, over 60 faculty across several disciplines are pursuing research solutions for some of the key environmental challenges of our time. ND-ECI focuses on globally significant, multidisciplinary research that can be translated into management and policy solutions to help make the world a better place for humans and the environment upon which people depend.

Better data for planning for your city’s future.

Our communities are facing the intensifying effects of climate change and need to be more proactive than ever. Yet, with so many competing priorities, how do cities decide where to act?

The Urban Adaptation Assessment (UAA) is an interactive database funded by the Kresge Foundation and led by the Notre Dame Global Adaptation Initiative (ND-GAIN) that collates a rich dataset within a visual platform to give leaders the data they need to make decisions on how best to adapt and prepare.

Encompassing data from over 270 cities within the United States, including all 50 states and Puerto Rico, whose populations are above 100,000, the UAA allows you to explore the connection between vulnerabilities to climate disasters, adaptive capacities, and how these are distributed within a city.
