Purpose- The present study aimed to investigate the most important obstacles to the promotion of agricultural land consolidation in the rural areas of Kangavar County. This study seeks to answer a key question: What are the main obstacles to the implementation of agricultural land consolidation policy in the villages of the study area? Design/methodology/approach - The present research is an applied one conducted in a descriptive-analytical method; field work was used for data collection and factor analysis was used for data analysis. The population of the study included 1216 land users. Using Cochran's formula, 211 questionnaires were developed and randomly distributed among the users. The stratified sampling method was used to determine the number of samples in the villages. Cronbach's alpha was used to determine the coefficient of validity of the questionnaire in the village; the validity of the questionnaire was 0.816, which indicated the data were suitable for the research. Findings- The findings show that ‘the factor of investment and fund’ accounts for 14.445% of the variance, which is the most important obstacle to the development of land consolidation in the rural areas. However, the lack of support of government agencies and organizations, infrastructural weaknesses, individual factors, lack of creativity, lack of intellectual participation and trust, lack of management and production practices, lack of knowledge and awareness, and lack of access to communication facilities in rural areas are important constraints on land consolidation in the rural areas of the study.

Purpose: The main objective of this research is to develop and evaluate measures of rural housing landscape and the effect of strengthening on rural housing landscape of the village of Ahmedabad in Bahabad. The main objective of this research is to investigate the effect of rural housing rehabilitation on the landscape of Ahmadabad village from Bahbad which is based on the concept of landscape assessment. Design/methodology/approach: The purpose of this study as a methodology is applied, descriptive and field study. For data collection, documentation and survey method using a questionnaire for residents and technical observers have been used. To analyze the variables and indicators of the study, SPSS software and Chi Square and t tests were used. Also plan to analyze the effects of strengthening rural housing and perspective view and the village of Ahmadabad factor analysis, Bartlett test and the KMO indicator. Finding: Results indicate that strengthening many effects that may be positive or negative on the six performance indicators, aesthetic, economic, social and physical environmental and village have been studied. The results of the first test showed that some of the criteria related to performance indicators and aesthetic as due to zoning height, the proportion in the building, according to the settled units, compliance with the structure and the executive management and oversight of the village, in the 99% of variables appearance to furniture, flexibility and readability buildings, spatial unity and consistency of building styles, harmony between form, at 95%, which indicates a strengthening effect is significant. The second test results show that all the criteria of physical, economic, social and environmental influence of strengthening the fabric of the village of Ahmadabad to 99% to account for a significant level. Research limitations/implications: A lack of support from government agencies and the lack of statistical information on the type of tissue construction and existing buildings in the village Practical implications: According to research findings that show the direct relationship between the resistance and the perspective of the village, in the implementation of strengthening, the choice of materials facade and their implementation should be in a way that in addition to the rules and regulations of comprehensive plans and detailed and the high council urban Planning and architecture of Iran, offered to meet six criteria. Originality/value: Original innovation is in the provision of rural landscape assessment criteria. These criteria can guide those involved in retrofitting buildings rural housing. The proposed criteria can be used to analyze the beauty of the landscape, the villages designed to be used.

Purpose- One of the most important strategies facing drought and agriculture water shortage in North-West Iran is developing pressurized irrigation systems (PISs). In this regard, the present study aims to investigate the factors determining the adoption of the PISs by farmers in Ardabil Province. Design/methodology/approach- First, by drought zoning of Ardabil Province (by SPI method and GIS software), three regions including regions with mild, moderate and severe drought levels were determined. In the second step, using multi-stage cluster sampling, adopter and non-adopter farmers of the PISs were selected from three regions of study (n= 415). Also, the logistic regression was used to determine the affective and distinctive factors of farmers' groups. Findings- According to the results of logistic regression analysis, the predictive power of model was 0.622 and the sensitivity of the regression model to determine the model validation was obtained as 85.8%. Also, from among 17 factors of study, 7 factors of education level, farm income, knowledge about the PISs, the infrastructure for PISs, the effect of local weather conditions, the trust towards the optimality of PISs and the improvement in farm water management, positively impacted on the adoption and use of PISs. Among effective factors, knowledge about the PISs (Wald: 32.676), the trust towards the optimality of PISs (Wald: 27.855) and the infrastructure for PISs (Wald: 21.648) were the most important factors predicting to the decision to adopt and use PISs among farmers. Research limitations/implications- Since the study was carried out in a large area of the province, accessing the farmers and experts in the Ardabil Province was difficult and time consuming. Practical implications- The agricultural extension and education programs and PRA method, can provide the basis for the adoption of PISs among most of the farmers. Also, the infrastructure programs for the implementation and setting up of PISs are the priority of governmental projects to develop the PISs in the regions of the study. Originality/value- It seems that identifying and providing the necessary infrastructure for implementing pressurized irrigation programs should be based on the scientific needs assessment of the agricultural fields’ conditions in different regions. Also, proper the appropriate government funding and financial support for the appropriate infrastructure of PISs will increase the willingness of farmers to adopt and use of the PISs.
