Social and political tensions keep on fueling armed conflicts around the world. Although each conflict is the result of an individual context-specific mixture of interconnected factors, ethnicity appears to play a prominent and almost ubiquitous role in many of them. This overall state of affairs is likely to be exacerbated by anthropogenic climate change and in particular climate-related natural disasters. Ethnic divides might serve as predetermined conflict lines in case of rapidly emerging societal tensions arising from disruptive events like natural disasters. Here, we hypothesize that climate-related disaster occurrence enhances armed-conflict outbreak risk in ethnically fractionalized countries. Using event coincidence analysis, we test this hypothesis based on data on armed-conflict outbreaks and climate-related natural disasters for the period 1980–2010. Globally, we find a coincidence rate of 9% regarding armed-conflict outbreak and disaster occurrence such as heat waves or droughts. Our analysis also reveals that, during the period in question, about 23% of conflict outbreaks in ethnically highly fractionalized countries robustly coincide with climatic calamities. Although we do not report evidence that climate-related disasters act as direct triggers of armed conflicts, the disruptive nature of these events seems to play out in ethnically fractionalized societies in a particularly tragic way. This observation has important implications for future security policies as several of the world’s most conflict-prone regions, including North and Central Africa as well as Central Asia, are both exceptionally vulnerable to anthropogenic climate change and characterized by deep ethnic divides.

Recent studies provide strong evidence that climate change worry leads to climate action. However, there is a need for more studies on the conditions under which climate change worry triggers climate action or causes mental disorders. In this regard, we investigated the relationship between climate change worry and climate action and evaluated the role of participants’ knowledge of climate change and natural disaster experience in this relationship. The moderating function of climate action in the relationship between climate change worry and climate-related mental disorders was evaluated. Furthermore, the impact of climate change worry on different climate actions was also researched. Data obtained through an online survey from individuals aged 18–65 years old in a nationally representative sample in Turkey were used (n = 1229). The results show a positive impact of climate change worry on climate action. If climate change information creates a climate change worry, climate action occurs. Whereas climate change knowledge has a moderating role in the impact of climate change worry on climate action, experiencing climate-related natural disasters does not have such a role. However, experiencing climate-related natural disasters combined with climate change knowledge in the context of group impact leads to climate action. The climate change worry score had a positive effect on experiencing a climate-related mental disorder, but climate action does not have a moderating role in this relationship. The climate action most correlated with climate change worry is participating in voluntary activities to raise awareness among individuals. The contribution of climate change worry in different conditions to climate action is clearly supported by these research results. Therefore, climate change communication should be used to support the aspect of climate change worry that is transformed into climate action, and viable and sustainable environments should be created by considering each result of this study.

This article examines front-page images from a selection of newspapers portraying the loss of life, grief, and destruction caused by the cut-off low that hit the Valencian community, Spain, on 29 October 2024. This climate-related disaster was the first national catastrophe to take place since Covid-19 and resulted in at least 237 fatalities, leaving a devastated social and physical landscape. The research analyses images from a selection of regional, national, and international newspapers in the first few weeks following this disaster, examining graphic portrayals of the dead, the recovery of bodies, scenes of people in grief, and other unsettling images to explore possible underlying narratives, biases, and absences. The framework follows previous research on images of the Covid-19 pandemic in relation to ethics and the current context of instant image sharing, the effects of globalization, and the contemporary practices connected to the visibilization of death which vary depending on the nature of the crisis and the relationship to those affected. This article aims to contribute to broader discussions on the ethics of visual representation and the construction of meaning in times of crisis.

This paper presents a comprehensive review of centrality measures and their usefulness in transportation networks in the face of climate change adaptation. The focus is on understanding the importance of transportation nodes in the event of extreme weather events and climate-related disasters that may render them inoperable. The paper argues that if critical nodes can be identified, they can be better protected, while resources can be allocated to ensure their functioning in the event of such events. The paper assesses 17 centrality measures, including degree, closeness, betweenness, eigenvector, and Katz, and evaluates their usefulness and usability in transportation networks. The review highlights the need to reformulate these measures to take into account traffic- and transport-related parameters and variables. Without this reformulation, centrality measures only reveal node importance in a topological or structural way and fail to capture the true significance of the nodes in a transportation network. The reformulation enables the centrality measures to be properly applied in a transportation network and to expose the significance of their elements. This work has important implications for transportation planners and policy-makers in ensuring the resilience of critical transportation infrastructure in the face of climate-related disasters.

Small-scale flash flood events are climate-related disasters which can put multiple aspects of the system at risk. The consequences of flash floods in densely populated cities are increasingly becoming problematic around the globe. However, they are largely ignored in disaster impact assessment studies, especially in assessing socioeconomic loss and damage, which can provide a significant insight for disaster risk reduction measures. Using a structured questionnaire survey, this study applied a statistical approach and developed a structural equation model (SEM) for assessing several socioeconomic dimensions including physical impacts, mobility disruption, lifeline facilities, health and income-related impacts. The study reveals that respondents have experienced a stronger impact on direct tangible elements such as household contents and buildings as well as direct intangible elements with β coefficients 0.703, 0.576 and 0.635, respectively, at p < 0:001 level. The direct intangible impacts affect mobility disruption with β coefficients equal to 0.701 at p < 0:001 level which then further cause adversity to income-generating activities with β 0.316 at significant p < 0:001 as well. The overall model fit indices show highly acceptable scores of SRMR 0.068, RMSEA 0.055 and PClose 0.092. Thus, the SEM has successfully incorporated the socioeconomic dimensions of disaster impact and explained the impact phenomena reliably. This modeling approach will allow inclusion of various variables from different disciplines to assess hazard impact, vulnerability and resilience.

Indonesia, as an archipelagic nation, has about 150 million people (60%) living in coastal areas. Such communities are increasingly vulnerable to the effects of change, in the form of sea level rise and stronger, more intense storms. Population growth in coastal areas will also increase the disaster risk mainly because of climate change-related effects such as flooding, droughts, and tidal floods. This study examines the dynamic changes of urban population and urban villages in three decadal periods, from 1990, 2000, to 2010. To highlight different disasters that are increasingly tied to climate change, the analysis was conducted in the northern coastal area of Central Java province using village potential (PODES) data, which are routinely collected by the government. Results show that about 41% of people in Central Java province live in the northern coastal region and 50% live in urban areas. The numbers of hazard events within a distance range of 0–40 km from the shoreline are: flooding (non-tidal)—335; tidal flooding—65; and droughts—28. Based on this study, about half of flood disasters (non-tidal) occurred within 10 km of the shoreline, while tidal flooding accounted for 80%. Most of the climate-related disasters were found in rural areas at low levels of population growth, while in urban areas the disasters were found to be associated in less than 1% and in more than 3% of population growth.

This article reviewed bodies of existing local and international literature to provide multi-level insights into Africa’s readiness to standardise the adoption of social media and associated technologies in managing the numerous climate-related disasters in Africa, including storms, floods and droughts. Social media is making serious inroads in disaster management globally, except in Africa, with countries such as the United States of America, Japan, Haiti, Australia and so on, effectively deploying social media technologies in different cycles of disaster management, particularly since 2010. To encourage disaster management stakeholders in Africa to mainstream the involvement of social media in disaster management, this study examined Africa’s prospects using force-field analysis that assessed the social, financial, policy, technological and other factors that inspire or restrain the effective and comprehensive adoption of social media technologies in disaster management. The force-field analysis demonstrated that disaster management stakeholders in Africa have all the tools and conditions to adopt social media technologies in climate-related disaster management on the continent.ContributionDriving forces such as the steady Internet access and penetration in Africa, fast-growing social media penetration and adoption of mobile technology, Africa having four of the top 10 countries that spend the most time on social media globally, growing investments in Internet infrastructure and communalistic nature of African societies, among others, are pointers of Africa’s readiness to mainstream social media technologies in climate change-related disaster management.

Recent scientific consensus suggests that climate-related disasters are becoming more frequent and destructive. Consequently, increasing importance is given to disaster risk reduction (DRR) and climate change adaptation (CCA) in global governance. The projected global warming at 1.5 ºC and the climate variability that the Philippine archipelago experiences make DRR-CCA the key priorities of both the national and local government units. In this study, we assessed and measured the degree of mainstreaming of DRR-CCA in the comprehensive development plans (CDPs) of the five component cities in the province of Nueva Ecija in the Philippines. These are among the areas in Central Luzon that are susceptible to hydrometeorological and geologic hazards. We distributed survey questionnaires to 25 employees of the local government units in the five component cities in Nueva Ecija who are directly involved in planning activities. We triangulated their responses using archival data (review of written policies and plans). The main findings of the study indicate that in spite the presence of laws and policies on DRR-CCA, their implementation is only in the preliminary stages. The results also provide insights to policymakers and future researchers on the challenges and opportunities influencing the systemic mainstreaming of DRR-CCA in the province.

Background: During 2020 and 2021, over 50.2 million individuals were forced to leave their homes to escape the impacts of climate-related disasters, unable to practice social isolation or self-quarantine. A considerable proportion of them reside in densely populated areas with a lack of basic services such as water and sanitation and limited access to essential healthcare. This study aimed to estimate the internal displacements during 2020 and 2021 due to climate-related events, and review the evidence for proposing policy recommendations. Methods: Data from the Internal Displacement Monitoring Centre were used for assessing internal displacement by disasters during 2020 and 2021. In addition, the authors conducted a bibliographic review to analyse the responses to internal displacements in climate-related disasters. Results: There were 883 severe storms and 1567 flood events resulting in 50.2 million internal displacements globally. Through the documents reviewed, the legal framework, the vulnerabilities and current challenges of internally displaced persons, and the response policy recommendations were analysed. Conclusions: The increased awareness of displacement and migration, particularly driven by climate-related factors, aligns with international agreements emphasising coordinated action. This recognition becomes even more critical in the context of the convergence of climate-related displacements and the potential for future pandemics.

Given projections of future climate-related disasters, understanding the conditions that facilitate disaster preparedness is critical to achieving sustainable development. Here, we studied communities within the Wet Tropics bioregion, Australia to explore whether people’s perceived preparedness for a future cyclone relates to their: (1) perceived individual adaptive capacity (in terms of flexibility and capacity to plan and learn); and (2) structural and cognitive social capital. We found that people’s perceived cyclone preparedness was only related to their perceived individual flexibility in the face of change. Given that people’s perceived cyclone preparedness was related to individualistic factors, it is plausible that individualism-collectivism orientations influence people’s perceptions at an individual level. These results suggest that in the Wet Tropics region, enhancing people’s psychological flexibility may be an important step when preparing for future cyclones. Our study highlights the need to tailor disaster preparedness initiatives to the region in question, and thus our results may inform disaster risk management and sustainable development policies.
