Behavioral Adaptation to Heatwaves in Urban Netherlands: A Sequential Mixed-Method Inquiry

As heatwaves in cities intensify, understanding how urban residents adapt to extreme heat is critical. Yet, climate literature predominantly focuses on exposure-centric, spatial approaches, while bottom-up, people-first perspectives remain underrepresented. This study employs a sequential mixed-method approach to investigate behavioural adaptation practices among urban dwellers in the Netherlands.

In the first phase of the study, semi-structured, in-depth interviews (n=21) identified key themes that informed a Likert-scale survey instrument employed in the second phase to test a set of hypotheses. Subsequently, in phase two, a nationwide survey (n=1,849) across three urban typologies—Extremely Urban, Strongly Urban, and Moderately Urban—captured perceptions and behavioural practices related to heatwave adaptation.

Findings indicate that residents in highly dense, extremely urban areas have a lower behavioural adaptation score compared to the other two urban types. Additionally, ownership emerges as a key factor in the adaptation process; where homeowners prioritize technological adjustments, renters rely more on personal and cultural adjustments. In terms of risk perception, statistically significant differences exist between adults living alone and those living with a partner or family.

The tested hypotheses provide a nuanced understanding of specific vulnerability to heatwaves in the Netherlands, offering insights that can inform targeted urban design and planning strategies at the local level.
