Summary
Future climate change intensifies disaster vulnerability, increasing social inequity in community resilience. Our human-centric framework reveals widening socio-spatial divides, impacting vulnerable populations disproportionately.
Area of Science:
- Environmental Science
- Urban Planning
- Social Science
Background:
- Community disaster resilience is crucial for vulnerable populations facing climate change impacts.
- Social inequity in disaster resilience across various factors remains underexplored.
- Existing research lacks a systematic analysis of social disparities in resilience.
Purpose of the Study:
- To introduce a human-centric framework for investigating social inequities in community disaster resilience.
- To analyze social inequities in resilience related to human well-being under different climate scenarios.
- To quantify resilience disparities among sub-populations using established statistical methods.
Main Methods:
- Combined flood hazard maps (historical and future SSP scenarios) with a multilayer urban spatial network model.
- Evaluated residents' service resilience during flood events by analyzing road, community, and essential service networks.
- Quantified resilience inequities using the Gini coefficient and Lorenz curve for different sub-populations.
Main Results:
- Future climate conditions significantly increase affected communities and their vulnerability.
- Observed spatial polarization in community resilience due to the 'islanding effect', creating resource disparities.
- Social inequity in resilience is spatial and scale-specific, varying significantly across sociodemographic groups at local levels.
Conclusions:
- Widening socio-spatial differentiation in resilience can lead to dissatisfaction and hinder collective disaster response.
- Future climate variability, human well-being, and social equity must be integrated into disaster policies.
- Inclusive disaster response requires addressing the specific needs and vulnerabilities of diverse populations.

Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

01:50Global Climate Change

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

01:21Impact of Social Context on Individuals
269
Social psychology examines how the real or imagined presence of others influences individuals' thoughts, feelings, and behaviors. A key concept in this field is the role of social context in shaping behavior. The same individual may act differently depending on the social setting, due to the varying expectations and norms associated with each environment. This context-dependent behavior illustrates the influence of social roles, which prescribe appropriate conduct in specific situations.Social...

01:14Fundamental Attribution Error
13.7K
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...
