Possibilities for improvements of water resources management exist because of Iran’s vast areas of cultivable lands, big rivers and suitable sites for construction of dams in Zagross and Alborz mountain ranges, extensive aquifers, and suitable climatic conditions for cultivation of different plants. In addition to existing exploitation of the water resources of the country, there is some capacity for physical development of up to 30 bcm of water resources for consumptive uses and up to 50 bcm for energy production, while still observing all economic, social, and environmental limitations. Cultural support for developments in water resources management includes traditions and social institutions that have adapted over time to different geographical conditions, especially in arid and semiarid regions. The best adapted of such institutions allow for effective water resource utilization. Political conditions conducive to developing water resources management include extensive citizen participation in public affairs, strengthening of the parliamentary system, creation of nongovernmental organizations (NGOs), support of local management, and suitable political background for developing the water and agriculture sector. Existing installations and equipment include large and small reservoir dams, extensive irrigation and drainage networks, water transmission pipelines and pumping stations, treatment plants and water reservoirs, urban water distribution networks, and other facilities. Institutional capacity includes the possibility for experienced national experts to provide consulting and construction services in order to reduce foreign exchange expenses to a considerable extent.

Throughout human history, there have always been arrangements to avoid natural and abnormal events. Passive defense has been for the past decades and centuries the protection and protection of natural and human enemies, and one of the most important approaches and strategies in crisis management in cities has been passive defense; The principle of defense in the creation of cities has always been taken into consideration, so considering land use planning is one of the key principles in passive defense.The purpose of this study is to investigate the religious applications of passive defense in Mashhad; this research is an applied research. At the same time, by nature, it falls into the category of descriptive and analytical research, where the information is collected and categorized into documents, then the information is analyzed using Geographic Information Systems (GIS). Finally, multi-criteria decision making model (Topsis) is used to categorize the desired information. The results of this study show that most of the religious land uses are located around the city of Mashhad or in other words the primary core of the city. It can be said that the religious open-air area is in a much better condition in the districts one, two and three of Thamen, one district eight and one district 7. In the area of religious access, 47% of the access is between 0 and 500 meters, and with this distance of 2204842 vulnerable 1900460 people fall under this radius. Religious per capita also emphasizes the area of religious and vulnerable cadres indicating that areas one, three and four of the Thamen area, area four of the seven, are most favorable, and areas one and two of nine, area two, eight, Area Three, Area Seven, Area One and Two, Area 11, Area Three, Six and Four, Area Two, Area Three, Area Six, Area Three, Area Five, and Area Two, District 4 are in poor condition

So far, various theories in the field of political geography and its complementary branch, geopolitics, have been proposed by world-thinking thinkers. Ports, which are considered as politico-spatial components of coastal countries with the role of gateway geoeconomics and geostrategic defense-military, have always been considered by these thinkers as the link between the two geographical areas of land and sea. However, they have not proposed a separate theory with the centrality of ports in the game of powers. Therefore, in this study, while examining the role of ports in theories of political geography and geopolitics, we have tried to introduce the theory of "port power" in contrast to the former land power and sea power. Therefore, these two topics constitute our main goal in this research. The present research is a kind of basic theoretical research and the information and raw materials of the analysis have been obtained by library method and by using scientific books and articles as well as authoritative or reference websites. The results of the research show that the global geopolitical order of the 21st century is moving from land power and seapower to port power, and in the future the country that controls ports will rule the world.

Less than three percent of the planet's water is fresh. habitat in the macro sense depend on this water. Over the past few decades, due to population growth, agricultural expansion, industrial growth, climate change and successive droughts, human access to water has steadily declined, threatening the survival of the status quo and the sustainability of human life and civilization. This damage has attracted the attention of brokers and researchers to water security. South Khorasan province in eastern Iran is inherently a low-rainfall province with a hot and dry climate and has been involved in successive droughts and over-extraction of groundwater reservoirs for the past two decades. Has resulted. The present article, which is applied and the methodology is explanatory-analytical, and its findings are collected by the library method (books, publications and the Internet) are based on the hypothesis that in recent years, rainfall has decreased and aquifers in the region have decreased. It is associated with an increase in the number of disputes and lawsuits. The results showed that the increasing complexity of increasing water abstraction, declining reservoirs, decreasing rainfall, population growth along with government policies related to the expansion of agriculture has led to increased tensions, conflicts and lawsuits and has affected the province's water security.
