Due to the negative effects of agricultural production activities on the environment, especially water and soil pollution, one of the most important decisions in the agricultural sector is the optimal allocation of resources. In this study, an attempt was made to propose an optimal cultivation pattern for crops in Shiraz County with a multi-objective approach based on the water-food and environment nexus. The goals of this research include maximizing economic benefit, minimizing water consumption, minimizing fertilizer and chemical pesticide consumption, and maximizing food security. To solve the multi-objective programming model, the weight Lp metric method was used. The information required in this study included information on the production pattern, consumption of inputs, price, and performance of significant crops in Shiraz city in the crop year of 2019-2020, which was collected through library documents and completed a questionnaire by random sampling method. The results of the study showed that the area under cultivation of most of the crops of this County is reduced in the optimal pattern with the combination of goals. Onion crop was not prioritized and the area under cultivation of cucumber, lentils, barley, and beans is increasing. In total, this model will be able to reduce water consumption in the agricultural sector by 10.75%. The 10.26 percent reduction in the cultivated area of Shiraz County is associated with a 10.60 percent reduction in chemical fertilizers and a 10.37 percent reduction in chemical toxins. However, the cost of managing the consumption of production resources in this model will be a 9.71% reduction in the profit of the farmers of this city. Therefore, if the policymaker tends to lean toward environmental goals, he should consider that the main incentive for farmers to produce is economic incentives for production. Therefore, policymakers should find suitable solutions to make the farmers follow the proposed model.

Today increasing production capacity requires the special attention on agricultural sector and increasing investment in this sector. Achievement of a higher level of production considering the limitation of resources, is one the most important economic and developmental goals of every society and serious attention to regional capacities and directing regional investments toward development and expansion of production activities is one of the development necessities. In the present article it has been tried to first provide a framework of concepts and techniques of regional economy as well as a scientific and expert analysis from agricultural structure of Hamedan province. It has also been tried to identify the activities of the agricultural sector and investment priorities in the agriculture of this province and considering he sub-sectors of agriculture that have a higher priority, it has been tried to provide a proper context for agricultural growth and development. For this purpose, with the use of factor analysis, Numerical Taxonomy methods and based on the provided information and data by statistics center of Iran in 2012, investment priorities in agricultural sector have been determined and specified for Hamedan province. Results of this study indicate that production of crops, horticulture products, animal husbandry, livestock and poultry production, dairy production, food processing industries have the highest rate of profitability. Also, production of carpets, rugs, Jajim, Gabbeh and transportation and warehousing services have the highest capacity for employment.

Although the great dams built have a lot of social advantages and very expensive, but these dams might have some disadvantages that it cannot compensation. The main purpose of this case study research was to explore the impacts of Shohada dam formation at Joobkabod ulia rural in Sonqhor & Kuliaie County that by Using approach qualitative and content analyses. A total of 12 farmers who were lived in Joobkabod ulia rural which selected by Purposive sampling. Data collected using semi-instructed interviews, observation and field records and data collected continued until theoretical saturation. Also used two steps coding (axial and open coding). The results shown some negative impacts such as removing the road, product damaged by tourism, loss of agricultural land and no change in agricultural land. Also the advantages of are: make sure that water is available in summer and of Prevent floods.

Agriculture sector in Iran and some other countries of the world has a vital role in national development. Animal husbandry sub-sector needed meat of the society, creating related jobs and producing raw materials of some industries. Acquiring scientific and sound information of the current situation of regions are important and imitative step in improvement program planning. The purpose of this descriptive-evaluative study was to study of developmental levels of Townships of Zanjan province according to animal husbandry indicators. Secondary data (published and on the web data of related organization) and field data (by filling checklist from related organization) for 48 indicators (extracted from reviewing literature review and interviewing with rural extension and development and animal science experts) were used. Data units were omitted by dividing them to their average and then weighed by Mc Granahan method. The descriptive tables of indicators were added to geographical layers of townships in ArcGis 9.The results revealed that based on composite index (CI), Zanjan, Abhar, Khoramdareh, Ijroud, Tarom, Mahneshan and Khodabandeh townships were ranked respectively from first to seventh level. Also Townships of Zanjan province were ranked based on seven sub-indices, named as breeding and production management, livestock insurance management, related industries (processing, dairy industries, and slaughterhouses), private sector services, public sector services, infrastructural, human resources and extension-education. Based on the findings, some recommendations to improve animal husbandry sector in the province have been suggested.
