Organizations are affected by changing and competitive needs, regional and global laws and regulations, customer requirements as well as stakeholder expectations, and to achieve and achieve their desired results, need effective and efficient methods and systems. Therefore, the establishment of an integrated management system with different approaches such as quality, environment, safety and other issues required by the organization will be a desirable solution. Integrated management systems are actually aimed at integrating and integrating the three systems; Quality management, environmental management and safety management have been proposed in order to achieve a comprehensive management system. Organizations with the idea of continuous improvement and superior and creative attitude in scientific and correct management of resources need to implement this system.

The research method is combined and based on exploratory mix (qualitative-quantitative). The statistical population in the qualitative part was 40 elite professors in the field of management and in the quantitative part was 560 artisans of Qazvin province. Relative cluster sampling method was distributed among 350 samples. The validity of the questionnaire was confirmed by face and content method and its reliability was confirmed by Cronbach's alpha. Data were analyzed by exploratory and confirmatory factor analysis with SPSS and AMOS software.

The results of the qualitative section indicate that the model of promoting lean integrated management based on sustainable development in 4 dimensions of program, implementation, control and improvement is based on 5 axes.

The decline in environmental quality has raised public concern about environmental issues. Even in the greenest countries, policymakers face the significant challenge of understanding why environmental policies are often ineffective in addressing these problems. According to the 2024 Global Environmental Performance Index, Iran ranks 133rd out of 180 countries, reflecting a poor global standing and numerous environmental crises, including ecosystem conversion, biodiversity loss, increasing dust storms, drying wetlands and lakes, water resource depletion, land subsidence, and air and soil pollution. Contributing factors include a lack of robust development plans, ineffective environmental policies, outdated laws and regulations, and inadequate coordination among agencies and organizations. These issues underscore the urgent need for effective environmental policymaking to address the growing crises. This study, recognizing the importance of the formulation stage in public policymaking, proposes a model for developing environmental policies in Iran to address these challenges and reduce environmental pollution.

This study employed a qualitative research approach, incorporating both library and field research methods for data collection. Data were gathered through note-taking and expert interviews. The analysis was conducted using a thematic analysis strategy, chosen for its ability to extract meaningful insights from qualitative data, such as interview transcripts. The coding and thematic analysis process followed a comprehensive, step-by-step approach. Using purposive sampling, the research team interviewed 13 experts, including university professors, environmental researchers, executives from the Environmental Protection Organization, and managers involved in environmental policymaking. The interviews continued until thematic saturation was achieved, indicating no new themes or concepts were emerging. To ensure reliability, the test-retest reliability index was applied to the coding of the interviews. In this approach, a few randomly selected interviews were coded and then re-coded after a certain period to compare the consistency of the codes. This technique helped verify the reliability of the thematic analysis process.

The study results indicate that a model for formulating environmental policies to achieve sustainable development comprises eight key themes: economic factors, social factors, environmental factors, political factors, legal requirements, institutional capacity, key stakeholders in policy formulation, and the process of formulating environmental policies. Each theme plays a crucial role in policy development. Addressing environmental issues without a collective approach to these themes is likely to be ineffective. A fragmented approach to implementing these themes can lead to disruptions in development and significant harm to environmental resources. The results emphasize the need for a comprehensive approach that considers all these factors to effectively address environmental challenges and work toward sustainable developmen.

To effectively tackle environmental crises, a holistic approach must be embraced in environmental policy formulation. Social, political, legal, and institutional factors must be carefully considered to avoid severe challenges and complications. Active participation from community organizations, NGOs, citizens, and local stakeholders in policymaking can play a significant role in resolving environmental issues. This requires not only the restructuring of institutional frameworks to strengthen environmental governance but also a review of existing legal systems to ensure they are conducive to effective policymaking. It also highlights the importance of combining bottom-up and top-down policies to improve environmental performance indicators. Bottom-up opportunities from local communities and civil society, along with top-down engagement from legislative, executive, and judicial branches, are critical to shaping effective policies.

Climate and ecosystem changes in coordination with other factors have challengedmany basic paradigms of natural resource management. The purpose of this research was to knowthe correlation between water, energy, and food in Varamin Plain by the method of the mentalmodel and the dynamics of water, energy, and food correlation under political scenarios.

Data and relationships related to the mental model were collectedthrough interviews with the farmers and managers of the region using the Mental Modelersoftware. Data related to the correlation dynamics model was also collected through organizations,regional stakeholders and authoritative articles. The WEF nexus model developed for the studyarea consists of interconnected relationships for modeling water, agriculture and energysubsystems and their interactions. The simulation model was built using Vensim software, and thesimulation period was considered a 20-year period. The equations in each subsystem were createdbased on the basic equations of the system dynamics approach and the causal loop diagrams ofeach subsystem using relationships and positive and negative feedbacks.

The results of system dynamic modeling showed that the state of surface waterresources and water security of the plain will be 158 million cubic meters and -162 million cubic meters,respectively, during the period of 20 years, which shows the reduction of resources compared to theoriginal situation. The results of the model without applying the scenario showed that the volume of theVaramin Plain aquifer will decrease from 4000 million cubic meters to 2700 million cubic meters duringthe 20-year period. This shows that the policies of providing water resources, including the excessive useof wells, the development of urbanization and the creation of industries, as well as the lack of increase inthe productivity of agricultural water through modern irrigation methods, are the reasons for such aproblem. The application of scenarios for the allocation of the environmental needs of the Bandalikhanwetland showed that the plain will not have the ecological capacity to allocate water to the wetland, sothat in the next 20 years, the water security of the plain will decrease to 180 million cubic meters. Also,applying the scenario of increasing irrigation efficiency without increasing the cultivated area from 58%to 70% was effective in improving the reduction of agricultural water demand and increasing thecultivated area. The increase in cultivated area up to 41,600 hectares had a positive effect on agriculturalwater demand, but more than this amount caused the pressure on water resources to increase. Based onthe limitations of water resources and the reduction of water security in the Varamin Plain, the productionof the plain's products will also face a decrease. Due to its proximity to the city of Tehran, the VaraminPlain plays an important role in meeting the needs of the people of Tehran and the surrounding cities.

Examining the results and comparing the data showed that during the 20-year period,Varamin Plain will have an unfavorable situation regarding water resources and food production.The management of the resources of Varamin Plain requires a change in organizational,agricultural and developmental approaches. The development of solar systems in order to meetthe energy needs, the establishment of the wastewater treatment plant in Varamin and thedevelopment of the treatment plant south of Tehran, as well as moving towards sustainablecompression is effective in creating the stability of the plains resources in order to properly exploitthe resources. On the other hand, increasing the irrigation efficiency without increasing thecultivation area can help in balancing the current situation so that with the implementation of thepolicies of the sixth development plan, the demand for agricultural water will be reduced to someextent and the pressure on the underground water resources will be reduced.

Background and Theoretical Foundations: 

Blue economy, which has been become a principal part of political, economic and scientific diplomacy of various countries, focuses on economic growth based on sustainable exploitation and protection of marine resources. Marine aquatics production (capture fisheries and aquaculture) is one of the main sections of development of blue economy.  Iran (Islamic Republic of), with 1800 km borderline with the Persian Gulf, is the largest fisheries state in the region and has a high capacity in terms of blue economy.

A qualitative study was used to gather data through a literature review on blue economy. Forty-three scientific papers were analyzed and their primary concepts were illustrated by a word cloud graph.  

Analyses of the contents indicated that blue justice is a top ten concept to blue growth. As a consequence of overfishing and climate change, fish stocks of Iranian coastal waters of the Persian Gulf have mostly been depleted in the past few years. It has led to increasing the vulnerability of small-scale fishing (SSF) communities than before. Therefore, it should be paid a specific attention to these communities in processes of policy making to development of blue economy.

Showing the limitations of blue justice implementation in the region, the present paper demonstrated that blue economy will not developed without considering justice and its implementation is a task for government.

Chemical inputs in agriculture are the most important inputs that cause environmental and groundwater pollution. This is why agricultural activities and farmers' behavior can have direct effects on the environment. On this basis, a research study was conducted with the aim of analyzing and investigating the willingness to accept and consume biological inputs among farmers living in the villages of Meidawood sector of Baghmalek County in Khuzestan province using the survey method. The statistical population of the research included all the farmers of this region, among whom a sample size of 302 people was determined based on the Karjesi and Morgan table and by a simple random method (N=1400). The data collection tool was a questionnaire whose validity was confirmed based on experts' opinion and its reliability was confirmed by calculating the composite reliability index. Data were analyzed using SPSSv22 and Smart PLS3 software. The results showed that the studied farmers have a relatively favorable willingness towards the consumption of biological inputs. Also, there is a positive and significant relationship between farmers' attitude and willingness to accept biological inputs. In addition, the chi-square test between the willingness to consume biological inputs and different age levels of farmers was significant at the 1% level, and the results indicated that younger farmers were less willing to consume these inputs. The greatest willingness was among farmers aged 30 to 40 years.

Rural development is one of the important bases of national development of any country and people's participation in this process is important. Different countries have paid attention to this issue in the form of local governments and by delegating powers and responsibilities. With the approval of the law on the establishment of self-sufficient in the country's villages in 1998, there have been changes in the country's rural management. Since 2004, the villagers have taken charge of the village administration as the new trustees. The goals of this research was to investigate the role of rural assistants in the process of management and development of rural with an emphasis on environmental protection issue. The current research is of applied research type and analytical-descriptive method. The findings showed that the most crucial factors affecting the role of rural assistants in sustainable rural development are economic, cultural and social, environmental and infrastructure variables. Therefore, the village councils, with the participation of the people and the use of the power and talent of women and men in the councils and village councils, pay attention preventing the destruction of pastures, to the protection of forests, monitoring water harvesting.

In the twentieth century, with an emphasis on the principle of sovereign equality of states, a framework for global trade was established. Simultaneously, the importance of achieving balanced development between industrialized and developing countries was highlighted. This period witnessed the integration of development and global trade, alongside a significant increase in the production and international exchange of goods, which unfortunately caused considerable environmental damage. This situation revealed the necessity for more stringent environmental care and control within the structure of global trade. The concept of sustainable development emerged as a bridge between development and trade and quickly gained attention, leading to the formulation of multilateral environmental agreements within the framework of international environmental law. This article examines how sustainable development has been adopted and transformed into a global strategy, its influence on international policies, laws, and documents, and its implementation in international judicial processes. Nevertheless, the facilitation of environmental agreements by the rules of the world trade organization remains unclear, and the inconsistencies between trade practices and environmental measures have rendered the legitimacy and credibility of some of these actions ambiguous. This has led to conservatism and uncertainty in the implementation of environmental agreements, indicating that sustainable development can only be effectively applied in trade policies when it is integrated and intertwined with its constituent elements.

In this research, in order to increase the efficiency of the proposed supply chain network, a multi-product model with multiple objectives has been considered simultaneously. This model is designed to include four levels (supply, production, distribution, and first-class customers) in the forward network and four levels (collection centers, recycling centers, destruction centers, and second-class customers) in the backward network. The model has three objective functions: minimizing the total cost, minimizing the environmental impact, and maximizing the social impact of the supply chain. The cost objective function includes purchase cost (procurement of raw materials from suppliers and cost of purchasing returned products from customers), operating costs, inventory cost, transportation cost or flow transfer between facilities, and fixed setup cost. In the second objective function, it has always been tried to minimize the environmental effects that have adverse effects on the environment. In this article, the minimization of carbon dioxide gas caused by the transfer of flow between facilities is considered a function of the environmental objective. The third objective function includes the employee welfare index. Considering that the presented model belongs to the NP-hard category, the multi-objective genetic algorithm was used to solve the model, and finally the Pareto solutions were determined. Based on the obtained results, two economic and environmental objective functions are in conflict with each other. In the sense that the movement of each in the desired direction will require the movement of the other objective function in the unfavorable direction.
