Relationship between agricultural use area and fertilizer consumed with changes in groundwater nitrate concentrations is one of the direct methods of agricultural use on nitrate concentration and groundwater inflammation in each region that can manage managers in proper management. Help ground water resources. The purpose of this study was to investigate the relationship between changes in agricultural and chemical area of consumed on the increase in nitrate concentrations in groundwater sources in Ray plain.

In this study, Landsat 5 and 8 satellite images for the years 2008, 2011, 2014, 2017 and 2020 were used to monitor land use changes. After processing the images, the area of agricultural land was calculated. According to the statistics obtained from the amount of chemical fertilizer consumed and the qualitative laboratory results of nitrate concentration changes, the effects of these factors on each other and the mathematical relationships between the variables were tested with the Pearson correlation and linear regression method.

The results show that during the investigated period, agricultural land has increased and barren land has decreased. The consumption of chemical fertilizers has also increased. The level of nitrate concentration of underground water sources shows that during the period under review, the concentration of nitrate in underground water wells has increased. The analysis of the correlation coefficient also showed that at the error level of 1% (99% confidence level) there is a significant relationship between the concentration of nitrates in underground water with the area of agricultural land and the amount of fertilizer used. This means that as the area of agricultural use and the amount of chemical fertilizers increase, the concentration of nitrates in underground water resources also increases. In the presented regression model, the accepted square value (R2) is equal to 0.993 and it indicates a relatively strong relationship between the dependent variable (water nitrate concentration in underground water sources) and the independent variables (agricultural area and the amount of chemical fertilizer used).

The results indicate that with the increase in the area of agricultural land, the consumption of chemical fertilizers has increased in the research area, and due to the nitrate leaching process from the soil surface, the nitrate concentration in underground water sources has increased, which is one of the important reasons for the increase in nitrate concentration in the study wells.

Rules and regulations have tremendous effects on both effective water - energy management and dealing with main water-related challenges such as climate change, water shortage, carbon emission and water pollution.

In the study base on descriptive method, Iran water legal framework on water resource management is evaluated according to public participation principle.

The results show that Access to information as one of the pillars of the principle faces serious challenges. Lack of communication ways, inaccurate water quality and quantity statistics, several institutions responsible for issuing water permits in each catchment are challenges of Access to information. Participation in decision-making for both governmental and non-governmental organizations couldn’t satisfy mainly due to conflict of interests, restrictions on water and water rights exchange.

Groundwater affairs commission as a quasi-judicial body for water disputes resolution couldn’t realize access to justice in water sector due to lack of legal obligation to release data, restricted competence and structural problems.

Background and Propose:

 Due to the world's population grows, water, energy and food supply will be one of the most important challenges in the future. The predictions show the water, energy, and food crisis in the future of Iran and the world. The aim of this study is to review the global challenges as well as challenges in Iran in providing the required water, energy and food resources in the coming years for human societies. The water, energy and food nexus is an overall vision of sustainability that seeks to strike a balance between different goals, interests and needs of people and the environment. The water, energy, and food nexus can be a guide for sustainable development policy in the country to overcome the environmental and water crises in the future.

In this study, while reviewing the researches conducted regarding the water, energy and food nexus in Iran and the world, it has investigated the challenges and the necessity of investigating this nexus in Iran and the world.

Among the results of this research, the main challenges in the implementation of water, energy and food nexus in Iran can be mentioned, which include: sectorial policies and lack of integrated management, lack of financial resources to carry out projects related to water, energy and food nexus, lack of related information sources and lack of drafting upstream laws in the field of development of water, energy and food nexus.

In the end, among the conclusions of this study, it is possible to point out suggestions for the development of water, energy, and food nexus, which include: development of cooperation and coordination of all related bodies, including ministries, Islamic Council, universities, associations, companies, determining an institution for policy making and reaching a common consensus, creating and developing the infrastructure of the clearing market of affiliates, developing the digital economy for the development of new technologies related to implementation correlation plans for water, energy and food nexus, land preparation and systematic assessment of natural, social, economic and cultural factors. The reviews and results of this review article can unravel the problems predicted in the future of Iran and the world through correct management and policy.

In Iran, the issue of guaranteeing the right to clean air and its enforcement mechanisms has not yet found its real position in the legal system. The purpose of the article is to interpret the current situation regarding the right of citizenship, according to access to clean air, and the corresponding laws in Iran. To achieve this goal, European countries and corresponding laws have been chosen as benchmarks. Finally, providing solutions in the form of reasons for not defining the corresponding human rights laws and implementing them in the field of clean air will be the ultimate goal of the article.

The current research is of the type of applied research, especially, the inferential approach and the analysis of the existing conditions by the author were the main paths in the final impressions.

In Iran, the issue of guaranteeing the human right to clean air and its enforcement mechanisms has not yet found its real position in the legal system, specifically, elements such as the need for large investments, long-term and researched planning, and access to modern technologies for industrial use. The main challenges in defining and implementing citizens' rights are in the issue of access to clean air. In contrast, the European Union has always been a pioneer in creating a specific legal system in the field of dealing with air pollution.

According to internal and external reports and standards, the level of air pollution in Iran violates the rights to life and health, children's rights, and the right to live in a healthy and sustainable environment. In Iran, there is no sufficient legal system to restore citizen's rights in the issue of clean air, or if there is, they are not fully implemented

Many researches have been conducted in the field of social impact assessment of rural projects, but few researches can be found that examine the social impact assessment from the perspective of the stakeholders. This is despite the fact that the evaluation of social effects with the participation of stakeholders can lead to the formulation of more serious programs, better evaluation and management of conflicts in this field. Therefore, the present study investigates the social effects of the dam as perceived by the stakeholders in order to gain a deep insight using the qualitative method.

The current research has used the qualitative paradigm and the descriptive-interpretive research method to achieve the research goal. For this purpose, 10 key experts (Agricultural Jihad of Kermanshah province, Natural Resources Department and Environment and Water-Regional Department of Kermanshah province) and 28 local people of the villages covered by the project were studied. Data collection was done through focused group discussions, in-depth individual interviews, observation and document study with an average time of 25 to 40 minutes. The interviews were analyzed using the communicative content analysis method. Reliability was established through the control of people's opinions by other interview participants and the researcher's self-review during the data analysis process. Reassurance (validity) was also done by presenting all documents, notes and recorded interviews to the research team after analysis by the researcher.

The results of the interviews showed that the participants in the research evaluated the effects of the dam on the quality of life by expressing 38 positive concepts and improving the sense of place by expressing 5 positive concepts and believe that the implementation of this project will lead to a decrease in social capital by expressing 23 The concept of impact and damage to natural and environmental resources has been defined by expressing 10 concepts of impact.

The results of the research show the impact of the implementation of development projects on all social, economic and environmental aspects of the residents of the region. Therefore, planners and officials are advised to pay attention to the evaluation of all dimensions of development, especially the social dimensions of the residents of the affected areas, in order to increase the efficiency and effectiveness of the programs in the implementation of development interventions at the strategic level.

Environment, as one of the foundations of sustainability in various fields of corporate structure, has become a development strategy for effectiveness beyond the recommendations and suggestions of regulatory bodies. Human resources are considered as an integral part of the field of sustainability of environmental behaviors in any structure that focusing on green transformational leadership functions can provide the company with environmental advantages in social contexts. The Purpose of this research is Implementation of the Rough set process to determine the most important green transformational leadership function based on the competency axis of human resource sustainability.

In this research, where the main basis of analysis was the collection of Raff's pattern, an attempt was made to determine the dimensions of the research through several stages of content screening. Then, through two stages of Delphi analysis, an attempt was made to evaluate the reliability of the components and propositions as the basis of the analysis in order to finally determine the most important functions of green transformative leadership based on the competency axes of human resources sustainability.

The results of the research showed the proposition of collaborative competence as the basis of sustainable competence of human resources as a measure of influence on green transformational leadership mechanisms that can help the development and sustainability of environmental behaviors of human resources.

The obtained result shows that the collaborative competence of human resources strengthens the level of interactivity and intra-organizational communication in the field of decision-making of environmental issues and problems and it makes the dimension of the effectiveness of the opportunity in green transformative leadership to strengthen the atmosphere of creating ideas and supporting the innovations of human resources in the field of green functions in the oil company.
