The inappropriate utilization of water resources has led to water shortages and numerous challenges for humanity. Assessing water scarcity can significantly contribute to sustainable water resource management. The Water Poverty Index (WPI), as a composite tool, assesses the factors affecting the water condition in a specific area using five critical criteria: Resources, Access, Capacity, Use, and Environment. in the present study, Razavi Khorasan province was divided into 22 study areas, then the water poverty index was used to assess the water scarcity in each of them. WPI results revealed that the Darghz study area scored 50.63, indicating the best water condition, while the Kashmir study area, Red Mountain, and Khalilabad had the worst water conditions, scoring 20/20 compared to other regions. The average of WPI for the entire province was 34.41, indicating an unfavorable state of water scarcity in this region. The average values for the five criteria—resources, access, capacity, consumption, and environment—across the entire province were 19.41, 36.35, 31.23, 38.06, and 47.05, respectively, that according to Use and Resource criteria, water utilization in this province exceeds available water resources by a factor of 1.96. According to this, overexploitation of water resources, particularly in the agricultural sector, and neglecting sustainable development and resilience thresholds of natural ecosystems were identified as significant management strategic mistakes contributing to water scarcity in this province. Therefore, make a balance between water utilization and available resources, allocating a portion of water for the natural ecosystems requirements, and reducing economic reliance on agriculture, can serves as a roadmap for water resources management to effective water resource management and prevent further deterioration of the current situation.

Water is one of the major sources of development in countries and one of the greatest challenges of the present century, which can be the source of many of the positive and negative developments in the world, and in fact destruction of water resources is the destruction of the foundations of development. Researches has shown that improved management of conservation, exploitation and distribution of water resources is possible by reducing Governmental Entrepreneurship and stakeholders' participation and community participation through participatory management. Accordingly, social network analysis is considered as an approach to analyzing the relationships of local stakeholders for sustainable water resources management. The purpose of this research is to survey social network of local stakeholders using social network analysis in Sadr Abad village in Nodoushan catchment of Yazd. This research has been done on the basis of two connections of trust and participation using network level and subgroup level indicators. The results indicate that the degree of cohesion and social capital is moderate, and the stability and equilibrium of the network is also high, which indicates the high level of transmission in the relationships of trust and participation. Also, the correlation between the two connection of trust and participation, based on the QAP index, is 64 percent and it is appropriate and high level. Water management network in Sadrabad has the potential of greater cohesion and social capital, that prerequisite of it is to utilize the appropriate state of trust to increase participation.

This research was conducted to recognize Sibak-Sardab watershed rangeland potentials, evaluate and determine of suitability classes for sheep grazing. In this research, we used the proposed method of FAO (1992) and for information layers crossing used in Geographical Information System (GIS). In this research, sensitivity to erosion, water resources and forage production are three basic components of this study. We used the MPSIAC model for the sensitivity to erosion. The model of water resource suitability consists of three parameters, quantity, quality and water resource's accessibility. In the forage production model, we estimated the ratio of available forage to the whole produced forage in each vegetation type. According to the result 96% of the rangeland was in low suitability class (S3) and only 4% were in medium suitability class (S2). The most important factors causing the decrease in suitability were lower rates of available forage for the livestock, low forage production of classes, I, II and low palatability percentage. According to Actual use (22170 animal units in season grazing); and grazing capacity (15989 animal units) and also according to the high destruction because of heavy grazing; using a management method that can help to improve the rangeland condition is suggestion.
