Accelerated urbanization and development in disaster-prone areas have prompted urban authorities to adopt adaptation strategies to improve resilience and vulnerability to climate change and related disasters. Therefore, assessing resilience, vulnerability and their evolution over time becomes crucial in comprehending the dynamics of interactions between resilience, vulnerability, adaptive capacity, and urban spatial changes. Using an empirical study in Taipei Metropolis, Taiwan, we developed a Framework for Metropolitan Resilience-Vulnerability-Adaptation Assessments. This framework integrated spatial statistics with multicriteria decision-making analyses to assess overall resilience and capacities to tackle climate-related disaster risks, as well as their dynamics between the years 2001 and 2016. Our approach further employed resilience and vulnerability change models to explore the connections between adaptive capacities and improvements in resilience and vulnerability over time. Results indicate that low-resilience and high-vulnerability areas are significantly clustered and continue to deteriorate, particularly in fast-growing peri-urban and old-downtown communities. Moreover, comparing the effects of adaptive factors shows that increasing investments in transportation networks, public lands, and infrastructure does not lead to the improvements in resilience and vulnerability in the long-term. This implies that conflicts and trade-offs may exist between certain adaptation options and resilience building efforts. Numerous disaster-proof, public facilities and emergency responses may simply provide short-term benefits and potentially lead to maladaptive outcomes. They create a way to encourage large-scale land development and urban space changes, thereby locking in adaptation pathways focused on short-term resilience improvement, while strengthening the vulnerability loops in the long-term. Our findings provide metropolitan governors and stakeholders valuable insights into formulating more effective adaptive policies that reconcile resilience and vulnerability. They also broaden the scope for urban land use policy-making and metropolitan governance, providing opportunities to mitigate climate-related disaster risks more effectively.

Very little research has focused on climate impacts on aquaculture and the potential of climate information services (CIS) for aquaculture to support sustainable development goals 2030 (SDGs).¹ This study represents an effort to bridge this gap by conducting a first ex-ante economic evaluation of CIS for aquaculture in Bangladesh by semi-automating the extraction of data on climate-induced fish losses during 2011 to 2021 from popular online newspaper articles and corroborating them with available government and satellite datasets. During this period, Bangladesh faced an estimated loss of around 140 million USD for hatcheries, open water fish and shrimp. When validated with a year of country-wide official data on climate-induced economic losses to aquaculture, the damage reported from these media sources is approximately 10 percent of actual losses. Given this rule of thumb, the potential economic value of aquacultural CIS could be up to USD14 million a year, if 10 percent of the damage can be offset by appropriate services through a range of multi-sector efforts to establish and extend these services to farmers at scale.

Households in the coastal areas are more vulnerable to various environmental, social, and economic disruptions in terms of an intersectionality point of view. As a first step in mitigating potential effects on families, knowing how susceptible they are and, ideally, fortifying themselves against existing and potential disruptions is essential. Vulnerability and adaptive capacity could not be uniformly distributed between households owing to gender-based socio-economic disparities and inequities. This research, thereby, examined the vulnerability and adaptive capacity variation between households headed by males and females in the two coastal areas of an emerging economy like Bangladesh. This study utilized the Evaluation-based on the Distance from Average Solution (EDAS) method and Boosted Regression Trees (BRT) technique to conduct the analysis. The EDAS method has been used to analyze the adaptive capacity index. Using BRT, an innovative approach in the area, we showed that male and female-headed households are different in terms of their capability to adapt. The findings from this study suggest that the households led by females are more vulnerable than those headed by males in the study region across a variety of dimensions (social, health, economic, housing, and land ownership) from an intersectionality perspective. The study findings can provide a new outlook for the decision-makers in the coastal region on the vulnerability and adaptive capacity differences among the residents and thus lead to more efficient disaster management practices.

Early warning systems in disasters are crucial for life preservation and loss mitigation, endorsed globally by various UN agencies, governments, and disaster researchers. However, the social aspects pose significant challenges to the success of early warning. Using survey data from Sanya, a coastal city in China, our study explores the relationship between early warning services and community engagement. The primary warning channels are social media (SMS and WeChat), the Internet, and TV. These mediums, along with traditional and mass media, foster higher community engagement, like volunteer service and disaster risk reduction efforts. Satisfaction with warning service mediates these connections. Interestingly, families with chronic disease members are more likely to engage in community activities and utilize the Internet and social media for warnings. Notably, different patterns emerge when comparing families with and without chronic disease members, especially regarding Internet and social media usage. This study enhances our understanding of public adaptation to disaster warnings and provides insight for early warning services in the face of increasing climate change impacts and meteorological disasters.

The field of climate justice has been growing in relevance since its conception in 1997. This paper presents a comprehensive bibliometric and topic modelling analyses to examine the evolution and trajectory of the climate justice literature. We analyse 1,683 publications covering the period from 1997 to 2021, highlighting foundational works, influential authors, leading nations and institutions, and prevailing research topics within this field. We employ Latent Dirichlet Allocation to uncover latent research trends in the literature providing a crucial baseline for future scholarly endeavours and policy development in the realm of climate justice.

Our results show that the field of climate justice has grown exponentially from less than 5 papers annually between 1997 and 2005, to around 200 papers annually in recent years. This growth has seen a diversification of research themes with an increase in papers around the topics of health, vulnerability and adaptation, and policy and activism. There has been a consistent backdrop of publications around the topics of sustainable development and policy, and international relations and carbon emissions. Other prominent topics in the literature include education and food security, and human rights and Indigenous people. The field has moved from theoretical research to examining actual examples of climate injustices, with an increased diversification of topics.

Future research could usefully focus on exploring future generations and more-than-human entities; the integration of climate justice and climate activism with broader struggles for justice; re-thinking climate adaptation “success” and “effectiveness” through the lens of climate justice, and the ramifications of the Global Goal on Adaptation on climate justice led-approaches that are inclusive, build on human rights approaches, and extend the scale of adaptation analysis beyond the local. It is imperative to prioritise addressing the climate justice needs of those most affected by climate change, transcending national borders, generational gaps, cultural differences, and even the well-being of various species. Such a holistic approach will help inform and refine global climate policy and action.
