Abstract
Natural biological crises are a constant threat to human societies; Therefore, it is considered important to be prepared to control and prevent such disasters. In dealing with such urban crises, addressing the category of non-pharmacological interventions against infectious diseases can be a way forward. Therefore, the aim of the current research is to find the main effective indicators in the epidemic and to explain the environmental components resulting from the interaction and correlation of the relevant measurable indicators at the locality level based on previous environmental studies.
In this research, in order to obtain a community of opinion about effective indicators in epidemiological crises, a systematic search was first conducted using the keyword of pandemic resilience. For this purpose, several widely used databases such as Web of Science, Scopus and Elsevier were searched between 2013 and 2023. After checking the quality of the conducted researches, 42 indicators were selected. Further, in order to find out the underlying variables and identify the basic factors or criteria in order to explain the correlation pattern between the observed variables, the exploratory factor analysis method was used and SPSS version 26 software was used to analyze the data. Data from 118 Tabriz neighborhoods were used for exploratory factor analysis. After collecting the data, the process of change, standardization has been done to prepare the data and convert the raw data into percentage, growth rate, average and ratio. Then, the status of urban resilience components against epidemic diseases was calculated and normalized separately based on factor load for each neighborhood. Finally, the results were illustrated using Arc GIS software.
The findings of the research indicate that 42 indicators affecting the spread of epidemic diseases at the level of localities can be re-categorized into 8 components of accumulation, diversity and design, social factors, density, economic factors, health infrastructure, environmental pollution and green spaces. Also, based on the findings, it can be said that the condition of most of the components in the neighborhoods of Tabriz city is at an average level.
Based on the results, the effects of environmental factors on the transmission of Covid-19 are differentiated spatially. These components represent more than 82% of the changes in effective environmental factors.

Abstract
This research employs a systematic review approach to comprehensively evaluate environmental inequalities in Middle East cities. The Middle East, due to rapid urbanization and unsustainable development, faces complex environmental challenges that disproportionately affect low-income and marginalized populations. In this study, 60 scientific articles published between 2013 and 2023 from Scopus, Web of Science, and Google Scholar databases were examined. Statistical analyses revealed that environmental inequalities in this region have been exacerbated by weaknesses in coordinated policymaking and cultural-geographical differences. Temporal patterns indicated an increasing trend in these inequalities over the past decade, while thematic analyses uncovered detrimental impacts on public health, air quality, and access to water resources.Geographical assessments demonstrated that specific areas are more vulnerable to environmental hazards due to climatic and economic conditions. By identifying gaps in existing scientific literature and current policies, this research proposes strategies to enhance environmental justice and improve conditions in Middle Eastern cities. The results of this study can serve as a foundation for developing effective policy strategies and future research in the field of environmental justice in the region. By presenting a comprehensive analytical framework, this research contributes to a deeper understanding of the dynamics of environmental inequalities in the Middle East and paves the way for targeted interventions

Abstract
Considering that there are different forms of mass movements in the ChamGardlan watershed, especially along communication routes, agricultural and residential areas, it is necessary to create refugee maps Therefore, it is impossible to examine the factors influencing its situation in order to prevent and control this phenomenon. Therefore, during the field visits, geographical, physiography, land use, vegetation cover, soil, climatology, geography and geomorphology maps were produced in the GIS environment. The method of this research has been accomplished base of distinction of the geomorphological units while using aerial photos and crossing basis maps. Then, the effective factors on the occuration of mass movements were studied using logistic regression equations. So that, the factors such as slope, geological formation type, pedologic, climatic, etc. were taked into consideration as independant variables, and mass movements occurance frequency as function of mentioned factors.The result indicated that the effective factors related to frequency of land sliding happening in the area in arrangement, are slope, geological formation type and mass movements type (both kind and amount of salts in soil) and also landuse.
