Abstract

This paper presents a literature review of adaptive processes initiated by inhabitants without formal architectural expertise, leading to spatial changes in their homes within flood-prone areas. It is part of my ongoing doctoral research, which examines flood adaptation strategies undertaken by communities and households in informal settlements in the coastal region of central Chile. In the context of Disaster Risk Reduction (DRR), adaptation represents the final phase of the resilience cycle and can be classified as either planned or autonomous. Among these, autonomous adaptation refers to measures independently implemented by inhabitants without external guidance. Such actions are often driven by a combination of internal and external factors that motivate individuals to modify their homes. The paper seeks to reconceptualize the adaptive processes led by individuals and communities operating outside formal institutional frameworks. It emphasizes the architectural dimension of adaptation, analyzing how self-organized efforts bring about spatial transformations and contribute to disaster preparedness. Understanding these adaptive triggers, strategies, and their implementation is crucial for mitigating the adverse impacts of natural disasters in informal settlements. This research raises questions about the triggers for autonomous adaptation, examining whether these strategies are tacit (innate) or explicit (learned), how autonomous they can truly be, and analyzing their modes of implementation. The literature review identifies self-organized adaptation as a critical intersection of architecture and risk management. Focusing on processes driven by inhabitants, this study emphasizes their potential to foster a more prepared society while minimizing the risks associated with maladaptation.
