It is difficult to measure sustainable agriculture as a multidimensional concept. While it is relatively easy to express philosophical definitions of agriculture sustainability, providing an operational and methodology definition for evaluating the level of sustainability is difficult. Different methodological approaches have been formulated and developed to assess the sustainability levels of sustainable agriculture. However, there is no consensus on a comprehensive framework for identifying and selecting indicators, different scales of indicators, weighting and especially for aggregating individual indicators into a final composite indicator and rating of sustainability level. So, Evaluation of sustainable agriculture is an important challenge for agriculture researchers, agents, and policymakers. A comprehensive approach for stability analysis is the complexity of each other-need activities. That's why we need a comprehensive analytical framework for evaluating sustainable agriculture development and use. This study presents a certain methodological approach to evaluate and determine the sustainability of agricultural production at farm-scale which integrates all the individual indicators of ecological, economic and social stability into a comprehensive final index. In a case study, in order to test the proposed methodology, 22 individual indicators were selected. Then, a local condition of rice cultivation in Sari County was studied through an open review of 287 rice farmers.

Agricultural sustainability can be evaluated at different spatial scales including field, regional, national and even international measures. However, due to the specific conditions of each region, its natural environment, socio-economic conditions and agricultural techniques, necessity of a transparent scale is unavoidable. Most national indicators are not applicable at the scale of individual farms which are the purpose of the intended operations. In this study, 22 single index fields were selected to demonstrate and test the proposed methodology in a specific case study. Then, its relevance to the local conditions of rice cultivation in Sari County was studied by examining 287 rice farmers. Considering relative importance and impact of social, economic and ecological factors on the total sustainability, a methodology of Analytical Hierarchy Process (AHP) was applied by exploring the views of experts to determine the weight. Finally, the final composite indicator of sustainability was created through the integration of the three components of sustainability. A questionnaire was designed to collect data for the current farming operations. It consisted of three parts, namely: a) agricultural land management practices; b) economic performance and c) social characteristics of each farm. The questionnaire was designed in such a way to be completed in the shortest possible time. Thus, it was consisted of useful sections for measuring and providing information related to the entire system of agricultural production.

Discussion and conclusion
The results of this study indicate that 17.77% and 53.66% of rice production system is unstable and potentially unstable. While the sustainability level of social component was standing in a satisfactory situation, the sustainability level of economic and ecological components was still changing. In addition, farm sustainability was higher for those farmers using the method of biological control, low-product seed, agro-ecological management practices, owners of integrated land and participants in training and extension courses. The level of education, family labor, and the amount of self-consumption of rice are factors of positive and direct relations with ecological sustainability. On the other hand, the amount of rice production causes significant negative effects on it. Age, farming experience, level of education and the amount of self-consumption show a positive significant relation with social sustainability. In addition, education, land size, selfconsumption, the amount of produced rice and productivity index are in a significant positive relation with economic sustainability. In general, factors including education, extension communication, attending training courses and the information source of consumption play a key role in the increasing of farmers' awareness. In this study, to evaluate and compare the sustainability of agricultural production system in farm scale, a methodology framework has been provided by the combination of three components of sustainability, i.e. economic, social and environmental. However, it cannot be claimed that the proposed methodology is quite authentic to evaluate the complicated phenomenon of sustainability. Different facilitating assumptions are required for the use of this methodology. Of course, it has several advantages and also can be used for different purposes. Thus, the following hints are noteworthy in the methodology section:
- Variables and indicators of sustainability should be selected according to the specific circumstances and context of each area and the topic at hand, as well.
- Validation and preliminary test of indicators is ensuring their appropriateness and being measurable in the current conditions of any region.
- Weight allocation model based on the views of experts and AHP, can obviously show the importance of individual indicators in the final integrated one.
- The integration of the three components of sustainability into the final one should be due to the relative weight of the components.
- In the process of making indicators, positive and negative effects of indicators on the overall sustainability must be considered.

Rural industrialization has been greatly discussed by researchers in recent studies of rural planning and development. It is due to its positive effects of economic, social and infrastructural factors. Moreover, researches are looking for ways to analyzed approaches to reduce harmful environmental impacts of industrial projects, as destructive life factors of geographical territory, in rural areas. For example, according to Misra and Chyvta (1990); rural industrialization and the prevalence of non-agricultural activities can seriously affect the increase of social welfare and providing essential goods and services for rural households. Experiences by several countries prove the fact that every structural change that happens because of industrialization, not only has an important economic role in rural areas, but also led to self-repulsive economy, as well. In addition to studying positive economic, social and physical aspects, it is needed to do some preparatory studies on negative eco-environmental effects of rural industrialization for proper siting of such industries to reduce its harmful eco-environmental and human effects and improve spatial planning.

This study is an analytical explanation using library and field study. Field data have been collected by questionnaires after the identification of variables. Then, the required data have been collected in the intended study area. Samples have been managed in two different social levels: 36 people from local experts (Council and village head assistants) using census method for ICOLD matrices, and 295 individuals from the head of the households selected among local people of villages to assess eco-environmental effects of using Prometea multivariate technique in villages by the use of Cochran formula of Alpha= 0.05. The already designed questionnaires have been modified in ICOLD matrices covering several factors of physio-chemical, biological, socio-economic, and cultural infrastructure environments that include 41sub criteria, totally. Collected data have been finally analyzed by ICOLD environmental assessment method and Promote multivariate techniques.

Discussion and conclusion
One of the new challenges facing rural planning when it is getting applied, is the presence of two viewpoints: environmentalism, and rural industrialization. Villages are accumulation points of environmental resources that, according to the theory of Sustainable Development, it is essential to protect them. In addition, we aim at diversifying economic sector by supporting rural industrial projects. Integration of the two approaches needs the evaluation of environmental effects of industrial activities to help moderate the intensity of environmental effects of industrial projects in rural areas. In this research, we are intended to study industrial mining extractive project of Zanjan cement factory, located and operated in a rural district, to analyze its eco-environmental effects on rural areas. Results from ICOLD demonstrates that its eco-environmental effects vary by distance, i.e., the nearer the villages are, the more they will be threatened by these effects, or vice versa.
Results from promote technic confirm the same. Since, villages in disturbed areas within the distance of less than 5 kilometers from the factory or less than 1 kilometer from the communication route to raw stone mining site, show the highest level of eco-environmental instability. These villages include; Majid Abad (rated at 81%), Zarand (rated as 73%) and Mazidabad (rated at 67%), respectively. These villages are close to the factory and to the passage of vehicles carrying raw stone. Much of the physical area of the factory is located in agricultural land of two villages of Majid Abad and Mazidabad. Moreover, wind direction of the area mostly causes much of the pollution from factory dust distributes in other agricultural areas of MajidAbad. Another village which its eco-environment has been recently affected is Zarand, located in a foothill area near to the raw stone mining site. Dust from loading raw stones, noise pollution caused by the breakage of the rock, animals and wildlife breaking out of the area, and destruction of crops and plants are among the major environmental damage in this area. Thus, we suggest to reduce environmental pollution from factories in rural areas by reviewing some ways of factory activities such as transportation of raw materials, methods used for the extraction of raw stones, development of appropriate transport infrastructures, installation of air pollution controlling systems, increase in the plantation of more green spaces within the margins of the factory, good management of wastewater and their disposal system.

One of the implemented plans in this case is the rural guide plan which is prepared and implemented by Islamic Revolution Housing Foundation since 1362. Guide plan, as an outer variable, has impacts on rural structures including these four dimensions: physical, economic, social and environmental. In villages of Kermanshah County, lack of educational, health care and business services along with inappropriateness of rural passages, lack of housing resistance against natural disasters and consequently the increase of migration from villages to cities lead to preparing and implementing guide plan in some villages. So, in this county the guide plan has been implemented in 7.40 percent of the region (56 villages) before 2012. It seems that its impacts have been less than what is expected and its implementation is limited to some changes in physical texture and economic factors have been less considered. Therefore, this study tries to answer this question that to what extent does guide plan implementation lead to physical and economic change in the studied villages? What kind of relation is between physical and economic impacts of the plan? And regarding situational and population factors, is there a meaningful difference in physical and economic impacts of guide plan implementation in the studied villages?

This study is a descriptive-analytical one, regarding its methodology. For data collection and recognizing the studied villages, documentary method and survey have been used. Since this study tries to recognize the impacts and the outcomes of guide plan implementation, it uses an assessment after implementation which is an approach that is different from the purpose. This approach ignores the considered purposes in the plans consciously and deliberately and it aims to study all the impacts and outcomes of the plan that are beyond its purposes. Based on theoretical basis and background, 21 items in physical dimension and 18 items in economic dimension were defined. The method of choosing the studied villages is a selective method and according to the judgment; for choosing them some indicators such as natural condition, population, distance from the county, and the number of projects that have been implemented and the time duration of the plan implementation (5 years and more) are considered. Statistical population includes 2467 households that are residents of the mentioned villages; by using Cochran Formula 332 households were obtained as sample size and at the end 340 households have been chosen. Sampling method in statistical population is classified randomly. For data description, this method uses descriptive statistics like mean, frequency, and percent and to analyze them, it uses Kruskal Wallis Test, Spearman Correlation Test, Nounally Method and Standard Deviation Distance from Mean.

Discussion and Conclusion
Guide plan implementation aims to provide facilities in a fair manner by creating social, welfare, production facilities, necessary facilities for rural housing improvement and creating environmental, public services and guiding the physical development of the villages. The study's findings show that in physical dimension, the most impact of the plan regarding the respondents' point of view, is the appropriate orientation of rural development and development of infrastructural services. Despite of some shortcomings in development of green space, locating the disposal of sewages and waste, results show that guide plan implementation has a partly desirable impact on physical change in the studied villages. The impact of the plan for orientation of rural development and development of infrastructural services was more remarkable. This finding reveals that direct and urgent impacts of the plan on physical environment of the village are positive. But some implementation weaknesses and institutional inconsistency can be considered as the causes of the mentioned shortcomings. Economic changes are followed by physical change in villages among them the price change for houses that are near to main road is remarkable. The analysis of effective factors on guide plan implementation showed that villages located in foothills, with more population and with 10-20 kilometers distance from Kermanshah, had more physical and economic changes; these findings can express the less flourished capabilities of these villages that are emerged by guide plan implementation. Regarding to this study results that were mentioned briefly, to improve the guide plan implementation in physical and economic dimensions in Kermanshah villages, some suggestions are as follow:
1. Considering the obtained means according to respondents' point of view, unhealthy way of sewage disposal creates an inappropriate condition in terms of environmental health in the studied villages.
2. Regarding to improvement of passages in most of the studied villages, there is an urgent need for providing necessary mechanisms to maintain these achievements through educating people.
3. regarding to existing problems in physical and economic impacts that are especially obvious in projects such as paving the passages, developing green space and appropriate way of sewage and waste disposal, investment and engagement in light engineering and industry, lack of appropriate coordination between organization and Housing Foundation is suggested. In this regard, before implementing the guide plan it is necessary for other organizations and engaged institution in rural development to be coordinated and play an effective role in the process of implementation of the plan by providing clear guidelines for them. So, impacts and outcomes of the plan are not limited to physical cases that are inadequate and these lead to economic and social development of the village too.
