The present study aimed to investigate the adaptation intentions of wheat farmers in Kermanshah province regarding water scarcity by applying the developed norm activation theory. The research framework included behavioral intention and four psychological factors, including awareness of consequences, ascription of responsibility, self-efficacy, and personal norms. The sample size of this study consisted of 380 irrigated wheat farmers in Kermanshah province who were selected using multi-stage cluster sampling with proportional allocation. Data were collected through a questionnaire. The validity of the questionnaire was confirmed by experts, and its reliability was approved through pre-testing and calculating Cronbach's alpha coefficient and composite reliability for various research variables (0.863 to 0.894). The data were analyzed using SPSS26 and AMOS24 software. The results of structural equation modeling showed that the constructs of awareness of consequences, ascription of responsibility, and self-efficacy had a significant positive effect on personal norms. Additionally, personal norms and self-efficacy constructs had a significant positive effect on farmers' adaptation intentions, and the behavioral intention construct explained 62% of the variance.

 the process of water scarcity in Iraq has intensified due to natural and political factors, especially in its central and southern parts. In this regard, the current research has evaluated the trend of land use and land cover changes in Babol province in the center of Iraq and analyzed the changes and developments in the surface water resources of this region. The current research is based on the supervised classification of satellite images of Babol Province, Iraq, and in this regard, ETM+ sensor images of Landsat 7 satellite in 2003, OLI-TIRS sensor images of Landsat 8 satellite in 2013 and Landsat 9 satellite in 2023 were used and the maximum likelihood technique was performed on them. According to the results, during the first ten-year period (2003-2013), the surface water area of the region has decreased from 729.44 square kilometers to 174.14 square kilometers, which means a 76.13% decrease in the area of this group of lands. In the second ten-year period (2013-2023), the extent of surface water has increased from 174.14 square kilometers to 825.61 square kilometers, which indicates a growth of 374.1 percent. The results of the research have determined that factors such as the development of agricultural lands, the growth of urban and rural constructions, and climatic factors have emerged as the main factors of land use change in Babol province, and the cause and origin of land use changes in Babol province is not only water shortage.

Frequent occurrence of droughts in arid and semi-arid rural areas not only cause economic and social problems for farmer families but also affect their subjective well-being. Therefore, the objective of this study was to examine the farmers' subjective well-being during the drought. To do this Koohdasht’s farmers (N=23,600) were considered as the statistical population of which a sample including 379 farmers were selected using the cluster sampling technique. Data was collected using a questionnaire which its face validity was confirmed by a group of experts. To ensure of the reliability of the research instrument, a pilot study was carried out and the Cronbach's alpha coefficients were approved in an acceptable range. The findings revealed that while most households rely heavily on agriculture for their livelihoods, the impacts of drought on the basic resources of production have affected the subjective well-being of farmers. Also, the positive emotions and life satisfaction had the highest rank in measuring the subjective well-being of farmers. On the other hand, there was a significant difference between the subjective well-being of smallholder and non-smallholder, rainfed and irrigated, elderly and non-elderly, poor and non-poor farmers. Non-smallholders, irrigated, elderly, and wealthy farmers had higher subjective well-being. Based on the findings, recommendations were offered to increase the subjective well-being of farmers in the context of drought.

Water, as an element that plays an important and main role in human life, has become one of the most challenging issues in the current era. Almost most of the governments pay attention to the state of water resources of their land and look for solutions for the proper and better use of water resources by the people so that they cannot face the crisis of water shortage and reduction of water resources. while 31 countries in the world are currently facing water scarcity, and by 2025, another 17 countries will. They will also join this group due to the increase in population. One of the countries that has faced the challenge of reducing water scarcity is Iran. In the meantime, some provinces have faced the challenge of water shortage earlier than other provinces. Kerman province is one of the provinces where, due to the role of the agricultural sector in the employment and economic income of its people, the problem of water shortage and drought is evident in it. The main goal of this article is to analyze the effective solutions to reduce water shortage in Kerman province. Based on this, the main question raised is which solution is better and more effective to deal with water shortage in Kerman province? To answer this question, the descriptive-analytical research method and the tools of library collection and internet sites have been used and the research findings have been obtained. The results of the research show that Kerman province has water shortage challenges and water resource management models can be better and more efficient in solving water shortage problems and reducing water resources than water transfer projects (Beheshtabad and Safaroud).

Water stress is an important issue facing the world today. Some see it as affected by climate change and droughts, while others see it as poorly managed inhabitants of the planet. Every year, scientists and experts come together to think of a solution to the problem of water shortage. Iran is also one of the driest regions in the world due to its location in the arid geographical belt and desert belt and is thus no exception to this rule. The purpose of this paper is to analyze meta-analytic studies of water resources management. For this purpose, the collected articles were identified and categorized separately at both national and transnational levels. According to the studies, it was found that most studies at the national and transnational levels have focused on the status of water resources management and few studies have examined the causes and reasons for the challenges in water resources management. Also, studies have shown that adaptation and prevention, removal of economic barriers and the use of technology along with increasing stakeholder cooperation, developing a fully collaborative scenario as an alternative to the water transfer scenario, as well as thoughtful and comprehensive planning along with the awareness of actors and the collective will for good governance are some appropriate solutions to the water crisis and climate change. Despite such solutions, water resources management issues should have been resolved by now, but why is the water issue still a challenge? The research findings show that the solution to this problem is not reached by understanding the reasons, but only the favorable conditions versus the unfavorable conditions have been studied. Thus, this research seeks to find out how water resources management happens in this way.

Al-Azeem as an international riverine wetland on the border of Iran and Iraq, fed by domestic and foreign runoff, has recently undergone changes such as reducing discharge and increasing industrial pollution because of various natural and human reasons. In this regard, this fragile environment and its nearby villages (with low, reducing and semi-migratory population) must be studied through field and local research. This is an applied, descriptive-analytic study, with a documentary and survey method for data collection. The study population was 120 heads of households and/or available informant people over 25 years old in 10 villages of Dasht-e Azadegan County. The study questionnaire was prepared in consultation with academic experts. It is rated based on a 5-point Likert-type scale with regard to specific local conditions. The validity of the questionnaire was estimated based on the Cronbach α (0.812). Indexes of economic and social consequences of water scarcity were examined via using the Chi-square test at significance level of 0.05. Placing 83% of these outcomes in the first order, showed the negative effect of water shortage on social and economic lives of villagers. According to the findings and observations, we recommend some suggestions such as following water right of environment, lowering oil activities, executing necessary standards of environment, tourism promotion, and more research on feasible solutions of water shortage of the wetland were recommend.

In the last four decades, almost all of the Qanats of Borkhar in northern Isfahan have dried up. Agriculture-oriented surface water wells are converted into semi-deep and deep wells. Currently, due to the water deficit of these wells, the agricultural water supply of this plain is confronting a crisis. The type of agricultural water resource management in Borkhar has affected its development. Lack of water resources and absence of proper management of these resources have, along with other factors, changed the use of agricultural lands. This paper has utilized national and international scientific documents and reports, field study, interviews and results of questionnaires. The results of research and data analysis show that due to water deficit and lack of proper management of water resources in the production, transportation, distribution and consumption processes, agriculture in Borkhar has become unstable and is heading for destruction. Close cooperation is needed between the local people and the Water Organization regarding problems of water resource management. Land use changes in the future must also be carried out by study and research and a specific plan, and combination of traditional and modern techniques must be utilized in Borkhar.
