A Study of Urban Heat: Understanding the Challenges and Opportunities for Addressing Wicked Problems in HCI.

The Urban Heat Island Effect (UHI) is a phenomenon whereby cities tend to be hotter than suburbs. We frame the UHI as a "wicked problem" that poses a range of economic, healthcare, and social challenges. Our paper examines how different stakeholders negotiate complex value systems, collect data, and rely on collaborative platforms to address the problem of urban heat. Using documentary filmmaking as a research method, we conducted ethnographically-oriented interviews with participants including vulnerable communities, urban architects, microclimate researchers, and grassroots activists. Our findings reveal that unlike problems that can be solved using traditional HCI paradigms of distributed work, the UHI presents an entanglement of challenges that do not necessarily converge on a single solution. We conclude by discussing two opportunities for addressing wicked problems through social computing: knowledge systems for sharing hybrid data across domains and interactive forums for discourse among diverse actors.
