Classifying Social Adaptation Practices to Heat Stress – Learning from Autonomous Adaptations in Two Small Towns in Germany

Climate change adaptation planning and implementation have proliferated over the past years. However, we still lack an understanding of how society adapts itself outside of policy sectors and as part of what some refer to as “autonomous adaptation”. The way people respond to risk without deliberate interventions of public actors is not well-understood. Given the increasing occurrence of climatic changes that affect our daily lives, the topic is regaining attention with an emphasis on behavioral adaptation. This angle, however, does little to enhance our understanding of how society adapts collectively, and which practices and routines groups choose to adopt. This study investigates autonomous heat stress adaptation efforts in two small towns in Germany. Autonomous heat stress adaptation is approached through a lens of (social) adaptation practices. Small towns are understudied in adaptation research and have also played an only minor role when it comes to public adaptation planning, due to their lack of formal resources to develop public adaptation strategies. Based on empirical data, consisting of qualitative problem-centered interviews and a quantitative survey, concrete examples of (social) adaptation practices are identified and classified. The presented classification of practices goes beyond earlier attempts by generating insights on the role politics can play in providing a fruitful ground for enabling autonomous adaptation. The paper emphasizes the need for researchers and decision-makers to take a closer look at the wide variety of social adaptation practices already in place. This discloses insights on public-private adaptation mixes, which could ultimately also lift autonomous adaptation from its ad-hoc and reactive nature.
