Critical reflections on strategies for mitigating and adapting to urban heat islands

Abstract

ABSTRACTCities are described as urban heat islands (UHI) due to the intensity of the heat generated by urban activities. Buildings, for example, absorb and emit heat, which contributes to urban heat. Cities contribute to global warming, which, over time, influences climate change. Cities contend with these challenges concurrently through mitigation and adaptation strategies. Through their unintended conflicts and trade-offs, the strategies may impact each other adversely. What are typologies of these trade-offs and conflicts, and how do they influence the effectiveness of UHI management by governments? To answer this research question, this paper used the desktop, case-study and evidence-based research techniques. The paper found and discussed specific conflicts and trade-offs between UHI mitigation and adaptation strategies, as well as effective integration, innovation and evaluation management mechanisms. The findings should provide actionable insights for urban policymakers and planners, on UHI management and long-term climate resilience in cities.
