Climate change presents specific challenges for traditional communities, especially those facing rising sea levels in island territories, where relocation is imperative. The case study of Isberyala, a new Kuna indigenous resettlement in the region of Carti Islands (Guna Yala, Panama), exemplifies a process of proactive relocation. The research aims to identify potential maladaptive actions, so that this experience is considered for decisions to be made in further displacement processes, such as those that are being planned in the region. An analysis of the exposure conditions of the Carti Islands to sea level rise, and the assessment of urban resettlement project designed have been carried out. For an understanding of social perception of the relocation project, public managers, community leaders and academics were surveyed through a qualitative assessment. Findings show relocation to the continent entails a profound alteration of the indigenous cosmovision. Although, in general terms, the project was valued globally as an improvement in living conditions, it nevertheless involves a loss in the natural values of the environment and to the Kuna cultural heritage. Moreover, the resettlement project does not incorporate traditional models of housing and urban space structure of these communities, eroding sustainable development. In the context of other recent experiences in island communities, the Isberyala project highlights the difficulty of planning new resettlements considering traditional methods of construction and organization of relationship spaces to avoid maladaptation processes. This research proposes to add to the relocation debate, the need to incorporate local knowledge to ensure that adaptation strategies work.

Extreme weather events have cost billions of dollars in economic losses yearly in the United States and the world continues to experience natural hazards from the constant effects of climate change. Existing research studies have noted the increased frequency of natural hazards and called for mitigating actions to reduce disaster risk. Effective risk communication is critical in shaping natural hazard risk perception and deciding to take protective action. This study investigates the feasibility of adopting Virtual Reality (VR) as a method for natural hazard risk communication. Following a literature review, a structured large-scale survey was designed based on the Technology Acceptance Model (TAM) and administered to individual residents as participants for this study. Findings from this study suggest a strong relationship between the perceived usability and perceived ease of use of VR is related to participants’ gaming and VR experience. These findings indicated the willingness to adopt VR technology to communicate incoming natural hazards. In addition, the study results showed a negative correlation with age, which made older people less willing to accept the use of VR. At the same time, the previous disaster experience had contradictory effects on the perceived ease of use and perceived usefulness of VR. These findings are crucial additions to the existing literature as they suggest opportunities in disaster risk communication research for the adoption of new and emerging technologies. Future research will focus on segmenting populations based on demographics and experience distributions across a nationally represented sample.

Disasters are often regarded as catalysts for transformative shifts toward sustainability. This study highlights the central role of power relations in post-disaster developmental transformations. It argues that such transformations are driven not solely by rational decision-making, but also by the complex interplay of power dynamics among actors motivated by both formal and informal interests. Using the “actor-power-interest” analytical framework, this research examines the power dynamics and interests of key actors involved in the 1998 floods and the implementation of the Natural Forest Resources Protection (NFRP) Program in China. The study finds that the Chinese central government leveraged the 1998 floods as a strategic opportunity to implement the NFRP Program, dismantling local alliances centered around logging interests and shifting the balance of power toward central control. This transformation was facilitated by the government's use of coercive measures, financial incentives, and informational monitoring, all underpinned by the political will of key leaders and the financial resources accumulated following the 1994 tax reform. The findings underscore the critical role of power resources in enabling key actors to seize windows of opportunity and drive substantial policy changes.

The Horn of Africa drylands (HAD) encompassing Kenya, Somalia, and Ethiopia, recently endured an unprecedented multi-year drought from 2020 to 2023, causing devastating impacts. This study investigates these impacts and the dynamics of human adaptation in response to the drought, comparing it to earlier drought events (i.e., 2016–2018) to identify key lessons. First, drought impact data—covering milk production, trekking distances to water sources, and internally displaced persons (IDPs)—are analysed over time to provide a detailed overview of drought dynamics. Second, household survey data (n = 752) are used to examine community perceptions of the drought period and their adaptation strategies. Finally, agent-based modeling (ABM) simulations explore the interactions between mitigation, adaptation decisions, and drought impacts. The results reveal that, on average, the 2020–2023 drought had more severe impacts than the 2016–2018 drought, although the latter exhibited greater variability in impacts. Communities have adopted various adaptation measures to cope with drought effects; however, limited knowledge and financial resources remain significant barriers to scaling these efforts. ABM simulations indicate that enhancing extension services can boost the adoption of adaptation strategies, leading to increased crop and milk production. Additionally, the simulations suggest that water harvesting can mitigate drought impacts upstream, though it may reduce water availability downstream. These findings highlight the critical need for sustained investments in adaptation measures, timely and well-informed decision-making, and region-specific interventions while carefully considering the trade-offs associated with these strategies.

In mountainous settlements threatened by geohazards, various adaptive behaviors undertaken by residents to cope with long-term geohazard risk exhibit characteristics of bounded rationality. The spatiotemporal characterization of such collective adaptive behaviors offers significant insights into settlement evolution. Considering a geohazard-prone mountainous region in China as an example, we employ face-to-face questionnaire surveys and spatial data mining to investigate residents' long-term adaptive behaviors to geohazards. We constructed a comprehensive simulation model that integrates an agent-based model (ABM), geographic information systems, and a Bayesian networks (BN). This model meticulously simulates the decision-making processes of residents, influenced by policies, social dynamics, and environmental factors. A notable innovation in our study is the introduction of peer effects into the simulation model, a novel approach that reflects the interdependent and imitative nature of residents' adaptation processes. We also consider multiple scenario combinations to analyze behavioral patterns and collective emergence phenomena under different disaster shocks. The findings indicate that an increase in disaster occurrence probability prompts more residents to relocate to safer areas and heightens their disaster preparedness awareness. Moreover, our results show that different scenarios significantly affect residents' behavioral choices and sensibilities; interventions such as mandatory relocation and disaster subsidy policies can alter residents' adaptation strategies. The developed model offers a novel perspective and empirical foundation for geohazard risk management. This study elucidates the long-term evolutionary patterns of settlement aggregation and the phenomenon of collective emergence, thereby addressing the gap in simulating residents’ adaptive behaviors under the prolonged impact of geohazards.

Disruptions to medical infrastructure during disasters pose significant risks to critically ill patients with advanced chronic kidney disease or end-stage renal disease. To enhance patient access to dialysis treatment under such conditions, it is crucial to assess the vulnerabilities of community lifelines to hazardous events. This study proposes optimization models for patient reallocation and the strategic placement of temporary medical facilities to bolster the resilience of the healthcare system, with a focus on equitable outcomes. Utilizing human mobility data from Texas, we evaluate patient access to critical care and dialysis centers under simulated hazard scenarios. The proposed bio-inspired optimization model, based on the Ant Colony optimization method, efficiently reallocates patients to mitigate disrupted access to dialysis facilities. The model outputs offer valuable insights into patient and hospital preparedness for disasters. Overall, the study presents a data-driven, analytics-based decision support tool designed to proactively mitigate potential disruptions in access to community lifelines during disasters, tailored to the needs of health officials, emergency managers, and hospital system administrators in both the private and public sectors.

Natural hazards result in significant damage to infrastructure systems at regular intervals, and it is impossible to completely prevent or eliminate the occurrence of such hazards. Therefore, the concept of resilience becomes crucial in enhancing the reliability of these infrastructure systems against disasters and facilitating their swift recovery post-disaster. Resilience refers to the capacity of a system or infrastructure to withstand the impact of a disaster and subsequently return to its desired level of performance. Given the unpredictable nature of hazard occurrences and the uncertainty surrounding their effects, accurately predicting future losses or damages caused by these hazards is a formidable challenge. This research establishes a robust framework for assessing the resilience of housing infrastructure in the context of pre- and post-flood scenarios. By integrating a Bayesian Network model, the framework uses comprehensive information obtained from a detailed field survey conducted in a severely flood-affected region in India. The study also pinpoints the most crucial factor for enhancing the resilience of housing infrastructure, offering essential insights for designers, regulators, and key stakeholders.

The Sendai Framework for Disaster Risk Reduction has provided recommendations for disaster risk management policies. Several studies have contributed to them, generating knowledge about hazards and vulnerabilities. However, only some studies have delved into the capacities of municipalities to implement these national policies. This article analyzes the needs and organizational capacities of municipal civil defense units in Brazil and discusses cocreated proposals to catalyze national policy implementation at the municipal scale. The problem-oriented research conducted between October 2020 and December 2021 adopted mixed methods, composed of an online survey with 1993 municipalities, interviews with 31 municipalities' representatives across five regions of Brazil, and ten virtual focus groups with 260 participants. The qualitative and quantitative data were analyzed and summarized in five main topics that oriented the coproduction of proposals to catalyze policy implementation at the municipal level. These five main topics were centered on i) the professionalization of civil defense services; ii) funding sources to catalyze the implementation of municipal civil defense actions; iii) improving permanent communication among the national, state, and municipal civil defense units; iv) creating capacity development activities that are tailored to regional and biomes’ specificities; and v) fostering social and cross-sectoral participation in the civil defense policy.

Landed property often exhibits scarcity and strong demand, especially in the most sought-after places. Therefore, real estate investors may be attracted to locations such as flood-risk areas that may pose a substantial threat to human life and property. Furthermore, some environments may not have experienced floods in the past but are nonetheless susceptible to future occurrences. Flood occurrences are progressively more frequent because of several natural and anthropogenic factors, including urban sprawl. Nevertheless, construction projects and real estate investments in flood-prone areas persist globally. The objective of this study is to examine and comprehend the process by which perceptions of flood risk are shaped and how they, together with other variables, might impact investment choices in Lagos, Nigeria. The selection of the study locations (Ibeju-Lekki and Ikorodu) was based on their well-documented flood risk features, the hydrological estimates made by the Nigerian meteorological agency, and their high population density. An inquiry was conducted by administering questionnaires to property investors and estate agents within the study location. The findings highlight a clear stratification of motivations for real estate investment in flood-risk areas, with some factors emerging as the most significant drivers of decision-making. Results also suggest that investors place high importance on key considerations, potentially related to economic incentives or market opportunities, while other factors are perceived as less critical or more subjective. Understanding these motivations can help policymakers and real estate professionals better address concerns and develop strategies that balance risk and reward in these challenging environments.

In recent years, wildfires in the western United States have become more challenging to manage, with extreme wildfire behavior, larger fires, and longer fire seasons contributing to rising losses. Community and government leaders are realizing that suppression alone is untenable for future wildfire prevention and seek a wider range of risk reduction strategies from the community to the household levels. Simultaneously, these leaders are faced with the challenge of expeditiously rebuilding communities in the wildland-urban interface (WUI), sometimes after multiple fires that have occurred in quick succession. Although the post-fire recovery period offers opportunities to create safer, more fire-adapted communities, the dual goals of wildfire mitigation and recovery are often at odds. This study investigates changes in the post-fire policy environment across three California counties impacted by recent destructive and repetitive wildfires. Drawing on semi-structured interviews with government officials, wildfire professionals, and informal community leaders, we identify key tensions and synergies, or “flashpoints,” participants encountered when addressing risk reduction and recovery simultaneously. These issues emerged across three policy priorities: housing reconstruction, vegetation management, and economic recovery. Despite a largely shared view of wildfire as a chronic hazard, participants identified ways that risk reduction conflicted with the pursuit of housing restoration and economic development. Synergies included alignment between ecological recovery goals and risk reduction and instances of compromise in housing restoration, plan integration, and new partnerships forged in recovery. Based upon our findings, we discuss opportunities for advancing recovery and mitigation together that could translate to post-wildfire learning elsewhere.
