Purpose- Housing has been one of the basic needs of the human beings, and the settlements have also been considered as the basic needs in terms of human communities. In order to satisfy such needs appropriately, traditionally human beings have intended to supply such needs as dealing with their surrounding environment. The current research intends to define the indices of housing sustainability in order to investigate the sustainability of environment for rural housing in Marivan County. Design/methodology/approach - The required data was collected using documentary methods and field studies together with questionnaires. First, the environmental variables of sustainable housing for rural areas were defined. Next, using hierarchical sampling method together with Cochran formula, 295 rural households were selected as the sample of the study. The tool for collecting the data was a questionnaire with an acceptable reliability endorsed using pre-test, data analysis, and the calculation of Cronbach's alpha coefficient. Finally, in order to analyze the data, fuzzy interference system (FIS) was used within the MATLAB software. For mixing the results obtained from measuring the elements of environmental sustainability, the gamma fuzzy was used together with FIS. Findings - The results indicated that the environmental sustainability of rural housing in the current research included the values of 0.9, 0.7, and 0.5 for gamma fuzzy which respectively included 0.09, 0.22, and 0.52. This indicates that the environmental sustainability of rural housing is not desirable for the areas investigated in this study. Research limitations/implications - The most important problem with the current research was that the household heads in the rural areas could not be easily accessed for data collection. Practical implications - With respect to the results, it is recommended that the economic, cultural, and social conditions of the rural areas and the subsistence of their native residents should be in line with the climatic and geographical conditions of the areas. Originality/value - The results of the current research can pave the way for studying the sustainability of the rural housing, especially in the area which has been studied.

Purpose- The aim of this study is to identify and prioritize the obstacles to capacity development in gardening exploitations of the villages of Padena Olya in Semirom County. Design/methodology/approach - The present study has been done with causal - descriptive research method and the data has been completed using questionnaire and interview tools. In addition, 273 samples were chosen (using Cochran formula) from the family farming of Padena Olya Village as the statistical population and it has been completed by the random sampling method. Data analysis is done using both quantitative method, including descriptive and inferential statistics (path analysis and structural equation modeling using Amos Graphic software), and qualitative method, including Atlas software. Findings - The analysis of qualitative findings based on semi-structured interviews and focus groups showed that the main obstacles related to capacity development are of social, economic, and environmental dimensions. Data coding based on the grounded theory also showed the most important obstacles in marketing categories, the environmental obstacles, the obstacles of participation, also and educational and promotional obstacles. Finally, the quantitative data analysis using structural equation modeling, in addition to the obstacles presented in the qualitative model, has estimated production capacities and empowerment as mediating variables in the final model of capacity development obstacles in the study area. The economic obstacles with 0.33 and environmental obstacles with 0.17 have the greatest effect on the lack of capacity development of the exploitations in the study area, respectively. Research limitations/implications - They include the lack of cooperation of relevant organizations in the presentation of information, as well as the low interest of operators to participate in the interview and cooperation to collect the qualitative data which led to an increase in the duration of attendance within the study area, held more group sessions, and thus slowed down the process of study. Practical implications - We propose a plan for increasing government support to gardener in various affaires, such as increasing the share of insurance premiums. It is also advisable to attempt to determine the fair price or the guarantee purchase of the gardeners' products and create cooperatives to manage the sales and marketing of the product to remove the brokers and dealers. Originality/value - The present study stresses the capacity development process of horticulture through identifying and analyzing the effects of obstacles and capacity building and empowerment of farmers. This research explores the hidden variables and the barriers to capacity development in gardening exploitations.
