One of the strategies for sustainable development the agricultural sector is business to business collaboration in the form of a cluster that has attracted the attention of the world's scientific communities in recent years. The purpose of this study was to investigate the factors affecting development of cluster orchard crops business in Kermanshah province. Research paradigm, is mix-method qualitative – quantitative. The research method used in the qualitative section is the Grounded theory and in quantitative section is AHP. The population of the study included experts Industrial Township, Jihad-e-Agriculture Organization the Kermanshah province. The data collection process continued as the theoretical saturation was reached. The results indicated that 65 concepts were extracted from open coding; concepts were classified in 18 subcategories and 4 classes of cluster conditions, cluster development fields, intervening factors and effective strategies for the development of clusters. To prioritize these components, of AHP was used. The results of this section showed that in the created classes, the components of trust, access to manpower, cluster development and government support and support institutions are in the top priority. The results of this research can be used by rural development planners, experts Jihad-e-Agriculture Organization and Small Industries Organization and Industrial Township.

The big Sefidrud basin supplies the irrigation water of the Guilan fertile plain and provides requested water for strategic crop of rice in mentioned province. Water resource development projects in upstream of mentioned basin، risks supplying guaranteed irrigation water for Guilan plain. Present study investigates the effects of ten Sefidrud network inflow reduction scenarios under eight irrigation network conditions using regional mathematical programming based on positive mathematical programming and considering hydrological situations in central valley irrigation district of Guilan province. Requested data sets were obtained from Iran''s water resource management company، Guilan Water Company and different consultants'' researches. Acreages removed from irrigation module، avoided loss because of applying irrigation efficiency improvement projects and reduced gross margins of cultivation incentral valley irrigation district under different inflow reduction scenarios and network condition are the most important results of this study. Results revealed that nine percent reduction of the Sefidrud irrigation and drainage network inflow in central valley under current network condition caused 7. 6 percent of rice acreages and 7. 9 percent of total crops acreages to remove from irrigation module. Simulations based on changes in network condition showed the considerable effect of irrigation efficiency improvement policy on avoiding loss due to inflow reduction. Mentioned results provide a base for cost-benefit analysis of irrigation efficiency improvement projects in this irrigation district.

The Effects of Government Support Policies on Income Risk And Production cost of Selected Horticultural Products (Pistachio، Date، Apple and Citrus) Considering the importance of horticultural subsector in the Iranian economy with its share in production and comparative advantage، this paper aims to asses the impact of producer support policies using producer support estimate (PSE) method with emphasis on variables such as income risk and production costs. PSE was calculated for selected horticultural products (Pistachios، dates، apples and citrus) for 1989-2010 periods. The effect of PSE on the income risk was estimated using standard coefficient of variation of Cady and Della Valle (CCV). The results showed that government support policies reduced income risk by 52. 5، 0، 11. 5، and 31. 06 percent for date، pistachio، apple and citrus respectively. The effect of supporting policies on production cost was estimated using production cost function showed that production cost of date، pistachio، apple and citrus declined by 0. 4، 0، 0. 04 and 0. 05 percent respectively.
