The supply and distribution of sustainable drinking water is one of the most basic responsibilities of governments, and the protection and maintenance of water supply and distribution infrastructure is of particular importance. Currently, with the occurrence of natural threats such as drought and climate change in the country, the enemy can abuse these threats and carry out hostile actions such as creating disruptions or interrupting the provision of services as well as psychological operations to incite people against the government and sovereignty. Therefore, paying attention to drinking water infrastructure, industry, and agriculture is considered necessary and inevitable to increase resilience, continue essential activities, and facilitate crisis management. Our research method is practical and developmental in terms of purpose. The research approach is descriptive and analytical. The aim of this research is to provide an efficient model that helps identify the base threats and vulnerable points of the infrastructure of the border regions. In this article, in the form of a case study using the method of identifying and assessing the potential of natural and human hazards in a region (FEMA), firstly, the assets of the water and sewerage area of Marzi province have been identified and screened. Vulnerabilities are identified and assessed, and the risk of each asset is calculated. At the end, solutions are presented to reduce the risk to the water and sewage infrastructure of the border province.

Most of the methods used to measure the vulnerability of agricultural sector to drought, did not use the opinions of different experts or did not pay attention to the environmental and climatic differences of the regions, or gave the same weight to all the indicators used in the models. The question is how can assess the vulnerability by using the experts’ opinion from different domains? In this paper, the Bhattacharya and Das model were used to assess the drought vulnerability, and 16 experts were asked to determine the weight of the indicators using hierarchical analysis method. Then, according to the specified weights, a vulnerability map was prepared. The findings show that there is a difference of 3.5 times between the exposures of different zones. Also, a difference of 3.6 times was observed between the most sensitive areas and least sensitive areas. The adaptive capacity also shows a difference of 2.6 times in zones with maximum and minimum adaptive capacity. The findings also show a difference of 17.6 times in areas with the highest vulnerability to areas with the least vulnerability. No direct correlation between rainfall and degree of vulnerability to drought was also observed.
