Limitation regarding water resource along with skyrocketing population growth and its subsequent agricultural production consumption, demand more attention with respect to rational methods of water use and as well as improvement in irrigation system. This in turn will lead to provision of ample water resource and increase in agricultural crops as well as helping the country’s economy. Taking into consideration that agriculture is being consideration as major economic sector in rural areas, thus increase in production level along with decrease in its relevant costs could play a prominent role in social and economic trends of rural areas. The major objective of this study is to investigate the impact of practice of under pressure irrigation system on agriculture status of Khodabandeh County. The research method is based on descriptive – analytical as well as surveymethods. The population is composed of 800 of family households in Khodabandeh in 2011-2010 in which 168 were extracted via Kokrans formula and random sampling technique. This study more specifically deals with questionnaire which its viability was proven by extension agricultural experts. According to Chrombakhs reliability is amounted to be 0.79. This study further supported by SPSS software. This paper suggests that the implication of this irrigation system leads to some economic, social, and environmental impacts on agricultural situation of the study area. It is argued that according to T test with 99% confidence level, there exists significant difference with regard to per capita yield as well as provision of job opportunities comparing with past, that is prior to new irrigation system. Moreover, according to principle component analysis, economic, environment, agricultural inputs, and social factors with 17.261, 16.262, 14.729, 12.201 respectively are capable of explaining 60.45% of all variations.

After land reform, some actions have been done for rural finance by creating financial institutions such as credit cooperatives, Agriculture Bank and interest-free loan funds which were not successful in improving poor people livelihood. The studied area in this study includes a forest-mountain area that have small and sporadic villages and they are far from rural-urban continuum. In fact, these areas face with basic shortcomings because of their location in geographical isolation, lack of development of market, scattered villages, low population density and unavailability of services (including financial services). Researchers' preliminary studies in this area showed that in financial markets of the forest-mountain villages in Bandpey part of Babol county, for rural finance to meet their needs in micro level, include just officialpublic institutions and semipublic ones (agriculture Bank, credit cooperatives and Imam Khomeini Relief Foundation) that were not operating as rural financial institutions, so in the studied area this question is raised that in spite of the availability of financial institutions, why the level of financing services is low for villagers? Or in other words, why the available financial institutions could not be successful in attracting villagers? Therefore, the question is that what are the characteristics of financial institution for being successful in presenting financial services? This study aims to recognize optimality criteria in institutions that offer financial services in rural districts and tries to present a framework in rural financial institutionalization to help rural managers and development planners in rural financial domain such as Agriculture Bank, rural financial cooperatives, Imam Khomeini Relief Foundation and rural interest-free loan funds.

Ito consider the subject, a qualitative approach has been chosen in this study. So, 25 villagers that are residents of forest-mountain villages of eastern Bandpey in the county have been selected in a purposeful way; data collection has been done through in-depth semi-structured interviews to the theoretical saturation point. Following that, for more clarification and conducting in-depth interview, some follow-up and exploratory questions have been used. After each interview, all the statements were written on the paper. The obtained data from interviews were analyzed by using qualitative content analysis method (by the framework of an inductive approach). To increase the creditability and acceptability of data, these methods have been used: simultaneous data analysis, continuous observation, review by supervisors and selecting the main informants; accuracy and authenticity of data (stability) have been considered too, regarding these indicators: maximum number of participants, desirable relation with participants, accuracy in recording data, using external researchers and supervisors, long time engagement with research and obtained data.

Discussion and Conclusion
On the major subject that is extracted is "flexibility". On the major subject that is extracted is "flexibility". Flexibility of rural financial institution means the flexibility in time duration for loan repayment that does not interfere with planting season and the time that farmers and ranchers should spend money for their works. The results show that when the time of loan repayment interfere with the time that small farmers do not have cash money, this leads to excluding some people from taking credits and more than that those who were able to take the credit, could not gain enough profit. Availability is a criterion in rural space that have low level of livelihood, in faraway geographical location is of great importance. In one hand, availability means physical availability. This criterion can be understandable when rural forest-mountain area is understandable. These areas face with problems because of dispersion of villages and their distance from urban area to receive services including financial services. In another way, lack of finance leads to irresponsibility. Considering the findings showed that if rural financial institutions were dependent to government subsidies, offering credits to meet villagers' needs would be uncertain all the time. Another criterion, a sub-dimension of availability, is "having responsibility regarding to the conditions that farmers face with a social-economic problem". In one hand, small farmers and ranchers' livelihood is always exposed to natural, social and economic crisis (especially in forest-mountain regions), and in another hand, their week financial support make villagers vulnerable to these kind of dangers. The obtained results showed that optimality of a rural financial institution is related to offering services in all dimensions of financial services especially loan, saving and insurance. Therefore, one the most important issues for optimality of the rural financial institutions is the capacity of saving for small farmers and ranchers; they have high desire for saving. Official financial institutions and semi-official ones could not support this dimension of villagers' need with a commercial approach. According to the findings, villagers do not consider financial institutions as merely a monetary institution; they expect an appropriate financial institution not only offer monetary services, but also they expect them offer social services that need investment, or assignment of subsidies on their necessary products for their agriculture. The study findings showed that the assigned small loan is a loan for agriculture not for the farmer, and it rarely considers the need of the villagers for consumption. It is suggested that researchers on institutional issues and service institution in rural districts consider these issues in the time of occurrence and with direct observations and interviews; they should familiarize with their challenges and by a topdown and bottom-up approach, they can present a suitable strategy for the same areas to overcome their problems.

 Introduction
Proper land use requires knowledge of environmental power, and then knowledge about environmental capacity in management and economic planning, along with their protection, will bring economic growth and development. Therefore, there is a close and undeniable connection between the environmental capacity of an area and its function. The assessment of environmental capacity is based on the indicators appropriate to the type of zoning and mathematical rules. It aims to adjust the land use according to the region's characteristics to promote economic goals and preserve the environment.
Climatic and natural conditions are essential factors in the production and determination of plant species, and land use depends on the quality of these factors. Parameters such as temperature, precipitation, and humidity are crucial for the growth and development of different trees, including the walnut tree. The walnut tree is deciduous, large and wide from the broad-leaved group belonging to the Juglandaceae family and the Juglans genus with 21 species. The quantitative and qualitative characteristics of the walnut tree, such as wood, bark, leaves, and kernels, make it possible to use it in various industries such as soap making, paper making, wood and furniture industry, oil wells, oil extraction, pharmaceuticals, medicine, and dyeing, nutrition, purification of heavy metals from water and cleaning of soft metals, bulking of adhesives, with commercial and economic purposes. Therefore, the planting of this type of plant in susceptible rural areas, according to the 20-year vision document, in which special attention is paid to non-oil exports, including agricultural products, its export improves foreign exchange earnings and the economic growth of the villages. Therefore, considering the forestry value (wood value) and the edible seeds, the creation of uniform orchards of walnut trees requires the assessment of the capability of the regions according to the environmental components. 

 Methodology
The research method is based on the objectives of applied research and is descriptive-analytical. In this research, the desired data was collected from the organizations and scientific centers of the Ardabil province from 2007 to 2020. Then, after collecting and sorting, digitization was done, and finally, the layers were combined with the fuzzy coefficient operator model. Furthermore, the final map was obtained in 4 categories: desirable, suitable, relatively suitable and unsuitable in the GIS environment.

Discussion and conclusion
Even though the high sensitivity of the walnut tree to maximum wind speed and temperature thresholds (during the growth period and at the time of fruit ripening), the temperature is not considered a limiting factor for the planting of walnut trees in the province villages. The study of the average relative humidity of the air indicates that except for the villages of Pars-Abad and Bileh-Swar, Ardabil, the rest of the places are favorable and ideal for the growth of walnut trees. The investigation of the rainfall situation in Ardabil Province showed that the experts should supervise the planting of walnut due to the inappropriate amount of rainfall in Sarein, Nemin, Pars-Abad, and Ardabil.
Gardening at heights above and below sea level, such as Sablan, Talesh, Ghoshe-dagh, Bezghosh, Ag-dagh and Jalga Maghan mountains in Ardabil province, is a limiting factor in the planting of walnut trees. When planting at altitudes lower than 1500 meters above sea level, it is better to use species such as Chandler and Howard. For altitudes higher than 1500 meters above sea level, it is better to use Fernor species. The slope is not a limiting factor for the planting of walnut in the villages of this province, except in parts of Meshkinshahr, Ardabil, Khalkhal and Kausar. The final zoning map indicated that the areas with almost mild winters and dry summers, annual rainfall, relative humidity and moderate to good wind speed had a high potential for planting walnut orchards. According to the final map, of 17,824.6 square kilometers of ​​Ardabil province, 7,773 square kilometers are favorable areas (43.60 percent), 4,681.6 square kilometers are suitable (26.28 percent), 4,809.3 square kilometers are relatively suitable (26.98 percent), and 560.7 square kilometers are unsuitable (3.14 percent). Regarding geographic location, the ideal and favorable lands for walnut planting include the northern, central and eastern parts of the province, which includes 43% of the province.
