Breastfeeding Experiences of Mothers Staying in Temporary Shelter Areas in Disaster-Affected Provinces in the 2023 Türkiye Earthquake.

While the basic needs of breastfeeding women are similar to those of the general population, there are some specificities that must be taken into account when responding to an emergency. This study examines the breastfeeding barriers faced during a large earthquake in Türkiye and aims to investigate how infant feeding practices of breastfeeding mothers staying in temporary shelters after the earthquake were affected. This study follows a qualitative descriptive design with an inductive approach. It included participants who were older than 18 years of age, had babies no older than 1 year, and were breastfeeding mothers when the earthquake struck. Five main themes were identified through a content analysis of the interviews: (1) breastfeeding environment after the earthquake, (2) emotional impact, (3) change in social relationships, (4) physiological needs and problems, (5) specialized maternal and baby health services. Factors affecting mothers' infant feeding practices were crowded breastfeeding environments, stress and fear caused by the earthquake, decreased breastfeeding support due to changes in social relationships, difficulty in reaching basic physiological needs, and lack of professional health workers in the earthquake region. The most important factor affecting breastfeeding was the lack of suitable environments in which to breastfeed. There should be local, regional, and federal policies to support the privacy needs of displaced breastfeeding mothers.

Geo-spatial based cyclone shelter suitability assessment using analytical hierarchy process (AHP) in the coastal region of Bangladesh

The coastal district of Bangladesh is susceptible to cyclones, which cause significant damage to infrastructure, economy, and social structures every year. The importance of protecting lives and property in these vulnerable areas is a top priority, especially in times of cyclones and storm surges. Therefore, the identification of potentially suitable shelter locations is essential for disaster risk resilience planning and implementation in the coastal regions. In this context, our research focuses on Barguna, which has witnessed severe damage from previous cyclones over the last several decades. We aim to identify and map feasible cyclone shelter suitability by utilizing GIS, AHP, Hotspot Analysis, and Remote Sensing techniques. The use of advanced techniques enables a comprehensive assessment of multiple variables that influence shelter suitability, ensuring the selection of the most strategically significant locations. The goal is to enhance disaster preparedness and resilience in Barguna District, reducing the risk and vulnerability of its coastal communities to cyclones. Seven variables associated with cyclone hazards, such as elevation, slope, distance from roads and rivers, population density, land use, and cover, and proximity to healthcare facilities, are considered to identify the safest and most suitable cyclone shelter areas. The assessment of the appropriateness of shelter locations for the study area was facilitated by the collection of 181 GPS locations regarding existing cyclone shelters. The findings reveal that approximately 15.53 % (1956 ha) of the total land area is considered less suitable, 67.31 % (84763 ha) moderately suitable, 16.70 % (21024 ha) suitable, and 0.29 % (362 ha) highly suitable for optimal cyclone shelter establishment in the study area. This study has a major limitation due to the use of Landsat imagery, which may not always provide fully accurate image classification. To validate our methods, we collected existing cyclone shelter data and performed a pixel-based accuracy assessment, achieving high accuracy and confirming the reliability of our approach. This research addresses a critical gap in cyclone shelter planning, offering valuable insights for residents and decision-makers to mitigate cyclone risks not only in the Barguna district but also in similar coastal regions of Bangladesh. The framework developed in this study can aid non-government organizations and the government in determining the most appropriate locations to construct cyclone shelters to build a safer, more resilient future for the region, capable of withstanding the relentless threats posed by cyclones every year.

Revisiting a Drag Partition Model For Canopy-Like Roughness Elements

Turbulent flows over a large surface area (S) covered by n obstacles experience an overall drag due to the presence of the ground and the protruding obstacles into the flow. The drag partition between the roughness obstacles and the ground is analyzed using an analytical model proposed by Raupach (Boundary-Layer Meteorol 60:375-395, 1992) and is hereafter referred to as R92. The R92 is based on the premise that the wake behind an isolated roughness element can be described by a shelter area A and a shelter volume V. The individual sizes of A and V without any interference from other obstacles can be determined from scaling analysis for the spread of wakes. To upscale from an individual roughness element to n/S elements where wakes may interact, R92 adopted a background stress re-normalizing instead of reducing A or V with each element addition. This work demonstrates that R92’s approach results in a linear background stress reduction in A and V only when the ratio of n/S is small, due to a low probability of wake interactions. This probabilistic nature suggests that up-scaling from individual to multiple roughness elements can be re-formulated using stochastic averaging methods proposed here. The two approaches are shown to recover R92 under plausible conditions. An alternative scaling for the shelter volume is also proposed here using thermodynamic arguments of work and dissipation though the final outcome remains similar to R92. Comparisons between R92 and available data spanning more than two decades after R92 on blocks and vegetation-like roughness elements confirm the practical utility of R92. The agreement between R92 and this updated databases of experiments and simulations confirm the potential use of R92 in large-scale models provided that the relevant parameters accommodate certain features of the roughness element type (cube versus vegetation-like) and, to a lesser extent, their configuration throughout S. Last, a comparison between R92 and models based on first-order closure principles with constant mixing length suggests that R92 can outperform such models when evaluated across a wide range of roughness densities.

Non-invasive biomarkers for investigating urban metal exposure in neotropical bats

In urban centers, sewage treatment plants (STPs) serve as foraging and shelter areas for bats; however, they are sources of persistent pollutants that affect the health of these animals. This study aimed to investigate the impact of pollutants from an STP on the health of different species of neotropical bats from different guilds using non-invasive biomarkers. A conservation unit, the Silvania National Forest (SNF), was used as a reference area for comparison purposes. Blood, buccal mucosa, and fur samples were obtained for comet assay, micronucleus test, leukocyte profile, and metal concentration analysis in fur. Our results demonstrated that bats collected at the STP show a higher frequency of genotoxic damage, nuclear abnormalities, and an inflammatory response linked to infection than bats from the SNF. Regarding guilds, frugivores and nectarivores showed more pronounced responses to damage, but insectivores bats also showed relevant responses. While STPs are considered a source of pollutants, other urban sources of contamination likely contributed to these results. Still we encourage further studies using other non-invasive biomarkers, detection analysis of different pollutants in biological matrices, and the use of other wildlife species inserted in urban centers.

Effect of Stocking Density on the Growth of the Endangered Amazonian Fish Hypancistrus zebra (Siluriformes: Loricariidae)

ABSTRACTStocking density has a significant influence on animal homeostasis, and so is a crucial factor in the management of organisms in captivity and an important role in ex situ conservation of endangered species. Hypancistrus zebra is an endemic fish species from the Xingu River, Brazil—considered Critically Endangered since the early 2000s due to fishing pressure and, more recently, due to habitat changes resulting from the construction of the Belo Monte Hydroelectric Dam. The implementation of appropriate management in captivity is of utmost importance for its conservation, particularly in enhancing ex situ breeding techniques. This study aimed to evaluate the growth of juvenile H. zebra in aquaria with three different stocking density levels. The juveniles were distributed between three treatments, each with three replicates. We found no correlation between biomass and aquarium volume. The highest correlation coefficients were found between growth rates and densities related to the number of individuals per shelter area. Mortality rate was directly related to the initial number of fish in the aquariums, with larger populations showing higher mortality rates. The treatment with lower stocking density displayed the highest growth rate, while the treatment with higher density had the lowest growth rate, with a 23.38% difference between them.

Analysis of emergency assembly points for post-earthquake disaster management: a case study of Erzincan, Türkiye

The selection of emergency assembly points within the urban area holds significant importance for ensuring swift and effective intervention in the aftermath of a potential disaster until temporary shelter areas are prepared. In both historical and instrumental periods, Erzincan (Türkiye) has experienced major earthquakes resulting in significant loss of life and property. The likelihood of similar earthquakes occurring in Erzincan in the future remains high. Therefore, it is necessary to identify safe areas where people can assemble after an earthquake, moving away from hazardous zones. The aim of this study is to analyse the capacities and adequacies of emergency assembly points, which constitute a step in disaster management and enhance the earthquake resilience of the city, using Geographic Information Systems (GIS) based on selected criteria (accessibility, spatial distribution, proximity to healthcare facilities, size, capacity adequacy, and proximity to fault avoidance zones), and to propose solutions. The assessment revealed that the available assembly points are not homogeneously distributed throughout the city and are inadequate to meet the available building and population density. Therefore, in addition to the available 38 emergency assembly points, 67 new alternative emergency assembly points have been identified. The proposed emergency assembly points (in the 75–100% range) increased the number of neighborhoods within the 250 m service area by 43.75% and 42.5% for 500 m.The findings underscore the necessity for more comprehensive and effective planning for Erzincan in the event of a potential disaster or emergency.

Multi-criteria comparison analysis of spatial equity for emergency shelters in old and new urban districts: A case study in Wuhua District and Chenggong District of Kunming City, China

With the progression of urbanization and the concentration of populations in urban areas, cities are increasingly exposed to disaster risks. Emergency shelters play a critical role in disaster prevention and mitigation, as they are vital for providing temporary refuge and protection during and after catastrophic events. Assessing the spatial equity of these shelters is conducive to enhancing emergency relief capabilities and aiding in disaster risk reduction. However, there remains a lack of clarity regarding the comparative and quantitative disparities between new and old urban areas, particularly in developing countries like China, where urbanization is rapid and populations are dense. To address this issue, this study employed a combination of multi-source data and GIScience technology to analyze the spatial equity of emergency shelters in Wuhua District and Chenggong District of Kunming City, China. We evaluated the overall spatial equity of emergency shelters in both the old urban area (Wuhua District) and the new urban area (Chenggong District) using a comprehensive evaluation model with three criteria: evacuation population capacity, spatial accessibility, and the level of per capita effective shelter area. The results revealed that the old urban area suffers from insufficient effective emergency shelter capacity due to saturated construction land. More than 67 % of the shelters are short-term emergency shelters located close to buildings, which compromises spatial accessibility during earthquake disasters. The level of per capita effective shelter area, as indicated by SSTD, is 24.42 in Wuhua District, suggesting that the effective shelter area in each subdistrict is consistently low, regardless of its urban or suburban classification. In contrast, the new urban district boasts substantial effective emergency shelter capacities, both in the long-term and short-term types, surpassing the reference capacities. The rational spatial layout of various types of emergency shelters ensures that most regions with concentrated buildings are enveloped in accessibility time layers within a 25-min range. The SSTD index of Chenggong District is 349.23, underscoring the significant disparity in the level of per capita effective shelter area at the subdistrict scale, particularly in the district's urban villages and suburban regions. The findings of this study serve as a scientific reference for emergency management and urban planners to reasonably plan or upgrade shelter facilities, thereby improving urban resilience and promoting spatial equity in resource allocation among subdistricts, communities, and residents.

Smarter in the city? Lizards from urban and semi-natural habitats do not differ in a cognitive task in two syntopic species.

Urbanization occurs at a global scale, imposing dramatic and abrupt environmental changes that lead to biodiversity loss. Yet, some animal species can handle these changes, and thrive in such artificial environments. One possible explanation is that urban individuals are equipped with better cognitive abilities, but most studies have focused on birds and mammals and yielded varied results. Reptiles have received much less attention, despite some lizard species being common city dwellers. The Italian wall lizard, Podarcis siculus, and the common wall lizard, Podarcis muralis, are two successful lizards in anthropogenic habitats that thrive in urban locations. To test for differences in a cognitive skill between urban and semi-natural environments, we investigated inhibitory control through a detour task in syntopic populations of the two species, across 249 lizards that were tested in partially artificial field settings. Sophisticated inhibitory control is considered essential for higher degrees of cognitive flexibility and other higher-level cognitive abilities. In this task, we confronted lizards with a transparent barrier, separating them from a desired shelter area that they could only reach by controlling their impulse to go straight and instead detour the barrier. We found no differences between lizards in urban and semi-natural environments, nor between species, but females overall performed better than males. Moreover, 48% of the lizards in our study did not perform a correct trial in any of the 5 trials, hinting at the difficulty of the task for these species. This study is among the first to address lizard cognition, through their inhibitory control, as a potential explanation for success in cities and highlights one should be careful with assuming that urban animals generally have enhanced cognitive performance, as it might be taxa, task, or condition dependent.

Diversity, Distribution and Host Blood Meal Analysis of Adult Black Flies (Diptera: Simuliidae) from Thailand.

Understanding the factors associated with the species diversity and distribution of insect vectors is critically important for disease epidemiology. Black flies (Diptera: Simuliidae) are significant hematophagous insects, as many species are pests and vectors that transmit pathogens to humans and other animals. Ecological factors associated with black fly species distribution have been extensively examined for the immature stages but are far less well explored for the adult stage. In this study, we collected a total of 7706 adult black fly specimens from various locations in forests, villages and animal shelters in Thailand. The integration of morphology and DNA barcoding revealed 16 black fly taxa, including Simulium yvonneae, a species first found in Vietnam, which is a new record for Thailand. The most abundant species was the Simulium asakoae complex (n = 5739, 74%), followed by S. chumpornense Takaoka and Kuvangkadilok (n = 1232, 16%). The Simulium asakoae complex was dominant in forest (3786 of 4456; 85%) and village (1774 of 2077; 85%) habitats, while S. chumpornense predominated (857 of 1175; 73%) in animal shelter areas. The Simulium asakoae complex and S. nigrogilvum Summers, which are significant pests and vectors in Thailand, occurred at a wide range of elevations, although the latter species was found mainly in high (>1000 m) mountain areas. Simulium chumpornense, S. nodosum Puri and the S. siamense Takaoka and Suzuki complex occurred predominately in low (<800 m)-elevation areas. Simulium furvum Takaoka and Srisuka; S. phurueaense Tangkawanit, Wongpakam and Pramual; and S. nr. phurueaense were only found in high (>1000 m) mountain areas. A host blood meal analysis revealed that the S. asakoae; S. chamlongi Takaoka and Suzuki; S. nigrogilvum; S. chumpornense; and the S. striatum species group were biting humans. This is the first report of the latter two species biting humans. We also found that S. chumpornense was biting turkeys, and S. chamlongi was biting chickens, which are new host blood sources recorded for these species. In addition, we found that the S. feuerborni Edwards complex was biting water buffalo, which is the first report on the biting habits of this species.

A qualitative study to explore the immediate effects of cyclone Freddy on vulnerable learners education in Malawi

Purpose: The purpose of this study was to explore and identify effects of Cyclone Freddy on vulnerable learners in the flood prone areas both at primary and secondary school levels. Methodology: This study used a qualitative study method, which depended on mostly secondary data, using online interviews, reviews of online news articles, social media postings and United Nations reports and observations. Data was collected from the most affected areas of Blantyre Urban, Phalombe, Mulanje, Nsanje and Chikwawa districts. Purposive and convenience sampling was applied to the education institutions to get a deeper understanding of the phenomenon. The study also targeted teachers, parents, and students of the affected schools in the districts. The tools for collecting data were questionnaires using face to face interviews, focus group interviews which mostly included observations. Information was coded and participants in this study were assured of for anonymity and confidentiality. Results: The results of the research provide a better understanding of the impacts of cyclones on education systems and possibly give pointers in terms of preparedness of education systems to cope with disasters of the same magnitude in future. Additionally, due to lack of rapid response on Psycho Social First Aid (PFA), a lot of the victims succumbed to trauma and depression. This made the go back to school campaign very difficult especially for the most vulnerable communities. Contribution to theory and practices and policy: The research findings validates the theory of disaster preparedness that exhaust all areas of rapid response as a recovery strategy, such as evacuation, supply of immediate basic needs in the areas of shelter, food, beddings and psycho-social support especially (PFA). The Government (DODMA) through Ministry of Education and other line Ministries, the donor communities and implementing partners should embark on harmonizing efforts for disaster preparedness and recovery strategies to speed up operations. Watt, (2019), suggests that, while it is a requirement to take pro-active measures to put in place realistic strategies for future natural disasters, education should also be taken as a priority in the recovery strategies.

Pengaruh Perbedaan Ukuran Intake Kontraksi Terhadap Laju Aliran Di Ruang Uji

The contraction cone or intake is a very important part of wind tunnel design because it has a high impact on the quality of airflow in the test section. The design of the contraction cone aims to create the air pressure required at the time of entry of the test section without experiencing much turbulence. This research was conducted using an experimental method, where in this study it was carried out by testing, making 3 intake components or funnels of different sizes. The calculation results obtained funnel 1 contraction with a value of 11,466 m3 / s, funnel 2 contraction with a value of 12,266 m3 / s, and funnel 3 contraction with a value of 12,533 m3 / s. These results show that the size of the contraction affects the wind flow rate inside the test chamber. Where changes in the size of contractions will increase the wind flow rate, which is caused by the increasing size of the contraction cross-sectional area so that the shelter area or wind flow area that will move towards the test room increases in size or area

Microplastic pollution on historic facades: Hidden ‘sink' or urban threat?

Despite the increasing concerns surrounding the health and environmental risks of microplastics (MPs), the research focus has primarily been on their prevalence in air and the oceans, consequently neglecting their presence on urban facades, which are integral to our everyday environments. Therefore, there is a crucial knowledge gap in comprehending urban MP pollution. Our pioneering interdisciplinary study not only quantifies but also identifies MPs on historic facades, revealing their pervasive presence in a medium-sized urban area in the UK. In this case study, we estimated a mean density of 975,000 fibres/m^2 (0.10 fibres/mm^2) for fibre lengths between 30 and 1000 μm with a ratio of 1:5 for natural to artificial fibres.Our research identifies three groups of fibre length frequencies across varied exposure scenarios on the investigated urban facade. Sheltered areas (4m height) show a high prevalence of 60–120 μm and 180–240 μm fibres. In contrast, less sheltered areas at 3m exhibit lower fibre frequencies but similar lengths. Notably, the lowest area (2-1.5m) features longer fibres (300–1000 μm), while adjacent area S, near a faulty gutter, shows no fibres, highlighting the impact of exposure, altitude, and environmental variables on fibre distribution on urban facades.Our findings pave one of many necessary paths forward to determine the long-term fate of these fibres and provoke a pertinent question: do historic facades serve as an urban ‘sink’ that mitigates potentially adverse health impacts or amplifies the effects of mobile microplastics? Addressing MP pollution in urban areas is crucial for public health and sustainable cities. More research is required to understand the multi-scale factors behind MP pollution in large cities and to find mitigation strategies, paving the way for effective interventions and policies against this growing threat.

Successful forest restoration using plantation at high deer density: How neighboring vegetation drives browsing pressure and tree growth

Browsing can be an environmental stress to forest ecosystems, where the composition and structure of plant communities depend on the balance between ungulate browsing and the ability of plants to tolerate and acclimate to this stressor. Tree planting is a management tool for restoring forest whose integrity has been compromised by the intensity and repetition of browsing. This tool may be insufficient when the stress leading to forest degradation is ongoing. Balsam fir (Abies balsamea (L.) Mill.) plantations are used on Anticosti Island (Quebec, Canada) to restore winter habitat for white-tailed deer (Odocoileus virginianus Zimmermann, 1780). To promote natural regeneration and growth of planted firs that are the staple winter forage of deer, enclosures were temporarily erected and deer densities reduced to decrease browsing pressure. The stress induced by heavy browsing at the time of fence removal and the density of competitors in regenerating cutblocks, however, could compromise fir growth and forest recruitment. Our objective was to identify factors influencing browsing intensity and balsam fir’s growth following fence removal. We aimed to identify factors influencing lateral browsing intensity and number of trunk reiterations on fir at the landscape scale, including distance and size of the surrounding forests, and at the local scale through intraspecific density-dependence and interspecific associative effects. We then sought to identify the stressors most influencing balsam fir growth among browsing variables and a neighborhood crowding index (NCI). We measured browsing intensity and growth of 114 balsam firs 8 years following planting and again 2 and 4 years after dismantling two management enclosures. At the landscape scale, our results showed that when balsam fir was more than 150 m from a forest edge, the probability of browsing was close to zero and consistently a low percentage of shelter area surrounding a focal fir led to a decrease in browsing pressure. At the local scale, intensity of lateral browsing increased with the NCI of white spruce (Picea glauca (Moench) Voss). Fir growth was negatively influenced by the additive effects of browsing and NCI. Finally, our results showed that 19.7% (95 %CI: 4.5%, 42.6%) of the effect of the surrounding vegetation on growth was mediated by browsing. The success of forest ecosystem restoration through planting depends on density of neighboring tree species that can generate environmental stress by influencing growth indirectly through browsing as well as directly through competition for resources.

Operating an overdose prevention site within a temporary emergency shelter during the COVID-19 pandemic.

A temporary emergency shelter was established inside the Commonwealth Stadium in Edmonton, Alberta, to reduce COVID-19 transmission and mitigate health risks among people experiencing homelessness. A non-profit organization, Boyle Street Community Services, opened an overdose prevention site (OPS) between February and March 2022 inside the temporary emergency shelter. People accessed the shelter-based OPS to consume unregulated drugs (via injection, intranasally, or orally), receive medical aid, access sterile drug use equipment, and be connected to additional health and social supports, without leaving the shelter. We conducted short interviewer-administered surveys with OPS participants to examine participant views and identify suggested improvements. The shelter-based OPS was accessed a total of 1346 times by 174 unique people. Fentanyl was the most common self-reported drug consumed (59%) and most consumption (99% of episodes) was by injection. OPS staff responded to 66 overdoses and reported no deaths. Survey respondents reported that the shelter-based OPS was convenient, with no need to forfeit their shelter spot or find transportation to another OPS. Respondents indicated that the OPS felt safe and accessible and reported that it reduced drug use in other shelter areas. Participants identified the OPS' exclusion of inhalation as a limitation. People who use unregulated drugs and are experiencing homelessness are at a higher risk of negative health outcomes, which COVID-19 exacerbated. Integrating temporary shelter/housing and harm reduction services may be an innovative way to lower barriers, increase accessibility, and improve well-being for this structurally vulnerable population. Future operators should consider incorporating inhalation services to further reduce service gaps.

The Danube Delta: The Achilles Heel of Danube River–Danube Delta–Black Sea Region Fish Diversity under a Black Sea Impact Scenario Due to Sea Level Rise—A Prospective Review

The Danube Delta is one of Earth’s biodiversity hotspots and includes many endemic, rare, and important species of both major conservation and economic value. This unique complex of ecosystems also plays a key role for Danube River and Black Sea fish fauna through its role as a natural safe buffer, shelter, feeding, reproduction, and smooth transitional area for a large number of fish species. Climate change is inducing a progressive sea level rise in the Black Sea, a fact that is expected to impact the delta’s key complex and dynamic habitats, biocoenoses, and associated biota, and last but not least the key taxonomic group, namely, fish. Around one-third of the fish species of this delta will be greatly affected, sometimes negatively, by this climate change scenario, another one-third to a lesser extent, and the final one-third not at all. The ecological positive feedback of fish can stimulate environmental change and is expected to be responsible for changes within Danube Delta ecosystems, and also for the near Danube River and Black Sea diverse matrix of aquatic and semi-aquatic ecosystems. Sea level rise in the Black Sea is considered to have been one of the main stress factors of the Danube Delta fish fauna in the past, and is likely to be the case in the future. In this spatio-temporal dynamic context, for the fish species under threat and risk, in situ-adapted management measures are highly required. The current work brings for the first time such a prospective knowledge about the potential impact on Danube River–Danube Delta–Black Sea coast fish diversity in the potential climate change–sea level rise scenario.

DISASTER SHELTER DESIGN AS AN ADDITIONAL FUNCTION IN UNIVERSITY OF BENGKULU’S MOSQUE

Mosque is preferable for shelter or refuge area in emergency situation from natural disaster in Indonesia. Therefore, additional function for a mosque is needed. This paper will discuss how to create a shelter mosque for earthquake and tsunami hazard. Site was located at University of Bengkulu, one of disaster evacuation area appointed by Bengkulu City regulation. Two main design variables used are the height level of evacuation floor area which determined by tsunami wave height prediction, and the convenience of site and building circulation path. Space syntax analysis were conducted to find the best circulation path design. Building design proposed as the result of this study are evacuation area on 2nd floor level or in the elevation of 8,5m, 3 site entrance along with the circulation path, and 4 vertical access to reach evacuation area on 2nd floor. The farthest access to reach evacuation area (height level of 16,5m) from site entrance is 12 minutes. This proposed shelter mosque are expected to be a placed for interaction, worship, and shelter for University academician and community around the campus when disaster occurred.

Spatial accessibility analysis and location optimization of emergency shelters in Deyang

The selection and planning of the location of emergency shelters have a crucial impact on the safety of residents and cities. In this paper, based on multivariate open geographic data, the Gaussian two-step floating catchment area method, K-means clustering, and particle swarm optimization algorithm methods are utilized to carry out a spatial accessibility analysis and location optimization of emergency shelters in Deyang City, Sichuan Province, China. The study shows that: (1) Deyang City’s emergency shelters are higher than the government’s relevant standard requirements in terms of major indicators such as single building area, total area and per capita shelter area. (2) The spatial distribution of emergency shelters in the study area is uneven and unreasonable, with accessibility from the urban center outwards, exhibiting a “high-low” distribution pattern. (3) The study suggests that 10 new emergency shelters can reduce the number of accessible blind areas by 43.31%. The study recommends that the assessment and construction of emergency shelter facilities in rural areas in China and globally should be emphasized. Reliable recommendations for improvement of emergency shelter planning in Deyang city are provided in the study results.
