Extended Abstract Introduction Natural and anthropogenic hazards have always endangered human society and settlements. These hazards disrupt normal life of human society and lead to crisis. In this regard, it is necessary for all sectors and institutions in the country to adopt smart strategies for dealing with these natural crises. Moreover, there should be a continuous emphasis on political and economic challenges. As an effective, efficient and precautionary strategy, passive defense explains related requirements and mechanisms, and thus can lead to a reduction of damages resulting from different crises. Materials and methods The present applied research takes advantage of a descriptive-analytic method. With the aim of reducing vulnerability of rural border hazardous areas in Marivan County, it investigates passive defense indices from a spatial and comprehensive perspective. In this way, vulnerable areas are identified and appropriate strategies are selected in accordance with the situation of passive defense in villages of this county. Required information was collected using documentary resources, especially basic geological maps and land use of the region. Then, indices were weighed using binary comparison method and fuzzy logic, and a final compiled map was prepared for the situation of passive defense. In this regard, 14 security, social and natural indices were selected as passive defense indices in accordance with the regional conditions. Afterwards, indices were weighed using AHP method and a Fuzzy weight was assigned to each layer. Accordingly, specified indices were mapped and compiled using Arc GIS. Results and Conclusions The present study takes advantage of a comprehensive and spatial approach to investigate human and natural standards of passive defense in villages of Marivan region in Iranian border. Findings indicated that human standards, including population of villages, distance from main roads and village centers are the most effective and important parameters influencing the status of passive defense in the studied villages. Also, final zoning indicated that the region is mostly in an appropriate status regarding passive defense. But regarding the spatial zoning, most villages (89 villages) are classified as average (quite appropriate). Regarding passive defense, more than 65% of the villages in this county are classified in a quite appropriate (average) class, which indicates that short-term and applied programs must be rapidly adopted to improve the fragile condition of these villages and prevent from deterioration of their status in passive defense. Moreover, more than 75 percent of low populated villages (i.e. fewer than 150 people) are classified as average. Since services and facilities are also allocated based on the village population, it should be expected that low declining population of villages rapidly increases vulnerability and reduces the desirability of their passive defense status. On the other hand, among six rural district centers in the study area, five rural district centers are in an average condition and only one is in a good condition. In rural planning system of the country, rural district centers are considered to be the focal point of rural areas, and provide the most developed services. Thus, it is necessary to use these rural districts as communicational centers for crisis management. 84% of rural district centers in the study area are in an average or fragile state, which may increase vulnerability and result in serious concerns regarding the status of passive defense in these villages. Also, random and normal distribution of these villages is considered to be a relative advantage for passive defense situation. But based on this principle, similar actions must be carried out in all villages to improve passive defense status throughout the rural district. According to findings and field observations, following solutions are offered to improve the status of passive defense in villages of this county: - Considering principles of passive defense in planning of rural development in the county. - Moving toward human centered passive defense through people participation and their education. - Moving away from a purely military and structural viewpoint toward passive defense by officials responsible for city development and security. - Paying attention to standards of passive defense with the aim of determining the most appropriate rural centers or rural districts. - Detailed and accurate short term investigation of the status of passive defense in rural districts and elimination of deficiencies and weaknesses, especially regarding human standards, with the aim of improving the status of these centers. - Compliance with the principle of spatial justice in accessing and distributing services and economic and social facilities in villages of the county with an emphasis on low-populated and remote villages.

Given that cities have the majority of the country's population and are often the economic, political, cultural, social and governance centers in countries, theirreadiness against crises (passive defense) should always be considered by the relevant experts. Organizing the city on the scale of the neighborhood (as the smallest and most effective urban unit) based on the requirements of passive defense, in order to deal with the crises (natural and man-made) and minimizing the hazards using geographical techniques and urban planning, are the objectives of this research. Therefore, the sixth district’s neighborhoods of Tehran’s 2nd region were selected as a case study and the results of the research were presented so that the possibility of generalization of similar surveys and studies in other urban areas would be provided. The present research is an applied- type, and the method of the research is normative-analytical. The scientific foundations of this research are based on the concepts of urban crisis management with an emphasis on geography and urban planning knowledge. In this research, after the recognition and evaluation of the present situation, the dimensions of the vulnerability of neighborhoods at the time of the crisis, the strengths and weaknesses, as well as the threats and opportunities of each neighborhood have been investigated with the passive defense approach, and the relevant conclusions have been drawn on this basis. Data collection was done based on library method and field studies, and a comparative method was used to provide the conclusions. In this research, the SWOT analytical technique was used to determine the strengths and weaknesses, threats and opportunities, as well as to provide strategies, policies and suggestions for necessary actions, and ArcGis software was used to display and analyze the descriptive data. The results of the research indicate that the attention to components such as city structure, urban texture, city form, urban land use, and finally the social contributions of residents of each neighborhood, can make it possible to organize urban neighborhoods based on the requirements of passive defense. The results of the research reflect the fact that paying attention to the components such as city structure, city texture, city form, urban land use, and finally the social contributions of the residents of each neighborhood, can make it possible to organize urban neighborhoods based on the requirements of passive defense.

The nature and essence of cities are intermingled with different issues such as political, economic, cultural, physical, juridical and environmental subjects. Therefore, “urban security” is a hybrid and complex concept. Because, city is influenced by many national and global units. Thus, designing a defensible urban space is one of the most important topics in securing metropolises. These spaces may include designing secure residential spaces, integrating public spaces with different land uses (commercial centers, governmental offices and other important organizations), controlling population density in important urban areas in different time periods and improving transportation systems and crisis management. With access to comprehensive information and general data, we can prepare a map of urban crisis and improve urban security and safety by implementation of optimal solutions. The pattern of spatial changes in cities and the framework of urban land use are among the most important issues in urban security and safety which indicate the importance of passive defense planning. Urban spatial planning is among the most important leverages which shows the vulnerability of different urban areas in the case of natural and human crisis in different time and locations. Urban security and safety depends on very complex patterns of density related causes and multiple effects. The complexity of these patterns suggests that providing simple commentaries and describing specific causes have a limited value in optimizing urban security and safety. The present article seeks to evaluate the role of passive defense in providing and optimizing security of metropolises, and suggests fundamental strategies for decreasing secondary crisis (after the occurrence of primary crisis such as flood, earthquake, fire and urban chaos. It seems that the passive defense approach is a new strategic view in establishing the security of metropolises and building a healthy and secure city.

Human beings have spent many decades trying to confront and overcome the nature. This is a continuous confrontation and fight against the nature whose unbounded forces enlarge and result in more catastrophes every day. Recently, this endeavor and fighting have appeared much more useful, due to the scientific development and related communication and information strategies in crisis management.
In competitive environment, survival depends on not being taken by surprise and success is the reward of taking someone by surprise. Therefore, the necessity of being prepared and having a coherent plan to fight natural forces in the context of crisis management is obvious. The present study tries to define crisis along with its different forms and investigate factors which result in the importance of these phenomenon in human societies. Moreover, it introduces concepts of crisis management and its different phases while defining Telegeoinformatics sciences. Finally, a Telegeoinformatic structure was proposed to launch crisis management system

The Persian Gulf is an area in the Middle East that is geopolitically important and attracted by world powers due to its unique features throughout history. In this article, the author seeks to investigate the explanation of the conditions, characteristics, issues and problems of the Gulf states as well as the causes of failure in the Persian Gulf states to establish a relationship between them at high levelsو and tries to provide an appropriate solution to prevent possible crises. This region has always been paid great attention by international powers due to the availability of special oil reserves and a special strategic location, due to which the powers in adopting their foreign policy inevitably have to take into account the effective components of the countries of the region and its potential conditions.
Accordingly, one of the issues that is important and somehow plays a key role in determining the foreign policy of the countries of the region is the Crisis. For this purpose, one of the issues that needs to be addressed in this regard, is to provide appropriate strategies and to adopt an active strategy to manage and overcome existing crises (Management Crisis) with regard to the need to create, maintain and consolidate the mutual or multilateral regional relations and the necessity of determining the strategy for political, economic and cultural cohesion of the neighboring countries in order to fulfil the security of the Persian Gulf region.

Urban crises after the unexpected incidents, especially earthquakes, are among the ongoing problems of urban societies and are becoming more and more important with the concentration of population in urban areas and the accumulation of activity and residence in them. Today, "pre-crisis planning" is one of the three areas of activity that is considered in agenda 21 on the development of human settlement planning and management in disaster-prone areas. (Travati, Hamid and Seyyed Amir Ayat, 1998, p. 81). Therefore, it is important that the crisis management planning recognize its position in the development of cities of our country more seriously, especially metropolises, and in this case the role of the green and open spaces in the planning of crisis management are undeniable. Therefore, in this paper, we tried to rely on the secondary and documentary data, field observations and surveys, and the use of quantitative analysis to evaluate the green spaces of the city of Borujen and assess the city's ability to face crises (especially earthquakes). The results of the studies clearly indicate a relatively favorable situation for green and open spaces in this city. But in order to achieve the desired status, measures should be taken to develop and normally re-distribute green spaces and equip them with suitable facilities in this city. Increasing the extent of green spaces is only justified by the role of the city as the supportive center of the province in the planning of crisis management.

Most of the buildings in the historical texture of Yazd have not been adequately resistant to earthquakes, and the rules, regulations and criteria have not been observed in their design. Most of these buildings are old and some of them are newly-built. The occurrence of earthquake entails serious and irreparable damages to buildings, facilities, equipment, natural resources, social order, historical and cultural heritage, activities, employment and income, organizations and executive agencies, transportation system and business, therapeutic, health, educational, religious, etc. functions, and will lead to crisis. The crisis management process requires implementation of measures before, at the beginning, during and after the crisis.
