   Although extreme heat can impact the health of anyone, certain groups are disproportionately affected. In urban settings, cooling centers are intended to reduce heat exposure by providing air-conditioned spaces to the public. We examined the characteristics of populations living near cooling centers and how well they serve areas with high social vulnerability.

   We identified 1402 cooling centers in 81 US cities from publicly available sources and analyzed markers of urban heat and social vulnerability in relation to their locations. Within each city, we developed cooling center access areas, defined as the geographic area within a 0.5-mile walk from a center, and compared sociodemographic characteristics of populations living within versus outside the access areas. We analyzed results by city and geographic region to evaluate climate-relevant regional differences.

   Access to cooling centers differed among cities, ranging from 0.01% (Atlanta, Georgia) to 63.2% (Washington, DC) of the population living within an access area. On average, cooling centers were in areas that had higher levels of social vulnerability, as measured by the number of people living in urban heat islands, annual household income below poverty, racial and ethnic minority status, low educational attainment, and high unemployment rate. However, access areas were less inclusive of adult populations aged ≥65 years than among populations aged <65 years.

   Given the large percentage of individuals without access to cooling centers and the anticipated increase in frequency and severity of extreme heat events, the current distribution of centers in the urban areas that we examined may be insufficient to protect individuals from the adverse health effects of extreme heat, particularly in the absence of additional measures to reduce risk.

2. Social Dimensions of Urban Flood Experience, Exposure, and Concern

   https://doi.org/10.1111/1752-1688.12676

   With growing urban populations and climate change, urban flooding is an important global issue, even in dryland regions. Flood risk assessments are usually used to identify vulnerable locations and populations, flooding experience patterns, or levels of concern about flooding, but rarely are all of these approaches combined. Furthermore, the social dynamics of flood concerns, exposure, and experience are underexplored. We combined geographic and survey data on household‐level measures of flood experience, concern, and exposure in Utah's urbanizing Wasatch Front. We asked: (1) Are socially vulnerable groups more likely to be exposed to flood risk? (2) How common are flooding experiences among urban residents, and how are these experiences related to sociodemographic characteristics and exposure? and (3) How concerned are urban residents about flooding, and does concern vary by exposure, flood experience, and sociodemographic characteristics? Although floodplain residents were more likely to be White and have higher incomes, respondents who were of a racial/ethnic minority, were older, had less education, and were living in floodplains were more likely to report flood experiences and concern about flooding. Flood risk management approaches need to address social as well as physical sources of vulnerability to floods and recognize social sources of variation in flood experiences and concern.

3. Age Differences in Perceived Preparedness for the Continuation of COVID-19 Pandemic: Important Role of Social Support

   https://doi.org/10.1093/bjsw/bcad205  

   Chen, Zhirui ; Cong, Zhen ( September 2023 , The British Journal of Social Work)

   This study examined the age differences in perceived preparedness for the continuation of COVID-19 pandemic; and tested the moderating effects of three types of social support, i.e., emotional, financial and instrumental support. Using a sample of 450 adults in Texas, USA from the research project ‘Vulnerability and Resilience to Disasters’ (October 2020 to January 2021), results of multiple linear regressions showed that compared with people aged over sixty-five, those aged eighteen–forty-four perceived a lower level of preparedness for the ongoing COVID-19 and there was no significant difference in perceived preparedness between individuals aged sixty-five+ and those aged forty-five–sixty-four. Receiving emotional and instrumental support was, respectively, more important for people aged sixty-five+ to perceive a better level of preparedness than for those aged eighteen–forty-four and forty-five–sixty-four. The findings highlighted the unique strengths of older adults in COVID-19 preparedness from the life course perspective and the importance of social support in their disaster preparedness. Based on these findings, social workers could incorporate the wisdom and experience of older adults into disaster management and develop age-specific interventions to promote preventive behaviours during future public health disasters.

4. Adaptive capacity beyond the household: a systematic review of empirical social-ecological research

   https://doi.org/10.1088/1748-9326/ac68fb  

   Vallury, Sechindra ; Smith, Ada P. ; Chaffin, Brian C. ; Nesbitt, Holly K. ; Lohani, Sapana ; Gulab, Sabrina ; Banerjee, Simanti ; Floyd, Theresa M. ; Metcalf, Alexander L. ; Metcalf, Elizabeth C. ; et al ( May 2022 , Environmental Research Letters)

   The concept of adaptive capacity has received significant attention within social-ecological and environmental change research. Within both the resilience and vulnerability literatures specifically, adaptive capacity has emerged as a fundamental concept for assessing the ability of social-ecological systems to adapt to environmental change. Although methods and indicators used to evaluate adaptive capacity are broad, the focus of existing scholarship has predominately been at the individual- and household- levels. However, the capacities necessary for humans to adapt to global environmental change are often a function of individual and societal characteristics, as well as cumulative and emergent capacities across communities and jurisdictions. In this paper, we apply a systematic literature review and co-citation analysis to investigate empirical research on adaptive capacity that focus on societal levels beyond the household. Our review demonstrates that assessments of adaptive capacity at higher societal levels are increasing in frequency, yet vary widely in approach, framing, and results; analyses focus on adaptive capacity at many different levels (e.g. community, municipality, global region), geographic locations, and cover multiple types of disturbances and their impacts across sectors. We also found that there are considerable challenges with regard to the ‘fit’ between data collected and analytical methods used in adequately capturing the cross-scale and cross-level determinants of adaptive capacity. Current approaches to assessing adaptive capacity at societal levels beyond the household tend to simply aggregate individual- or household-level data, which we argue oversimplifies and ignores the inherent interactions within and across societal levels of decision-making that shape the capacity of humans to adapt to environmental change across multiple scales. In order for future adaptive capacity research to be more practice-oriented and effectively guide policy, there is a need to develop indicators and assessments that are matched with the levels of potential policy applications.

5. Food systems and rural-urban linkages in African secondary cities

   https://doi.org/10.1186/s42854-022-00042-8

   Urban populations globally are expected to increase by approximately 2.5 billion by 2050. Much of this growth is taking place in African cities, where about 40% of Africans live in urban areas with populations of less than 250,000. In many of these cities, rapid urban growth has outpaced economic and social development, resulting in high levels of urban poverty and widespread food insecurity. As one response strategy, urban households may leverage their linkages with rural areas and other towns or cities to supplement their food consumption, for example through food remittances or food purchases from remote retailers. While this strategy has been found to occur among inhabitants of large cities where existing research on urban food systems and urban food linkages with other areas has focused, the dynamics in smaller cities are likely different. In this paper, we draw on data from 837 surveys collected in 2021 to investigate household food sourcing strategies across 14 urban areas in Zambia with populations less than 100,000. We find that rural-urban food linkages are dominated by grains while urban-urban food linkages are predominantly composed of higher value foods. Our data further suggest that urban area characteristics explain more of the variability in food sourcing behaviors than household level characteristics, and that urban food purchasing preferences in secondary urban areas are sensitive to the food retail landscape available to households. These relationships highlight the disparate role that rural and urban linkages play across cities of different sizes. They suggest a need for food-related policies to consider diverse urban food systems among smaller cities.
