Severe droughts have historically plagued Brazil's semi-arid region, leading to mass migrations and significant loss of life. Although these events sparked a unique coevolutionary relationship between humans water systems in this historical narrative remains largely unexplored from hydrological point view. This study delves into the multifaceted history development infrastructure region by compiling analyzing records, official documents, drought literature novels, newspaper reports. Thus, points that societal perception regional memory emerge as feasible pathways heritage toward community resilience droughts. Through analyse, valuable insights are provided for understanding human-water system interactions offering potential lessons other regions grappling with similar challenges.

Promoting pro-environmental behaviors among individuals in the community is crucial to increase resilience and address environmental challenges. However, a persistent intention–behavior gap often exists, particularly separate private or public spheres. Historically, addressing this has involved focusing on single moderating variables such as knowledge risk perception. Yet, few studies have examined it both spheres under combined influence of two variables. Our research plans bridge by exploring using conditional process models joint effects EK findings reveal larger sphere compared sphere, which highlights greater challenges translating intentions into collective actions within community. In behaviors, we observe most significant positive effect alignment when possess high coupled with low This combination facilitates bridging gap, fostering individual that can contribute resilience. Conversely, optimal occurs perception are high, facilitating translation actions. These insights offer targeted policy recommendations for governments policymakers, contributing deeper understanding increasing
