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- During recent decades, rural settlements in developing countries have undergone significant changes in global development and in pursuit of development, in accordance with the geographic conditions governing them. The intensity and direction of these changes have been different. The study of functional changes of rural settlements located in the central district of Ravansar County is the main objective of this study. Design/methodology/approach- This applied research is a qualitative research that has been carried out using Grounded Theory Method. The methodological approach of the dominant theory in this research is the Glaser’s (1978) approach. Finding- The findings of the research indicate that during a systematic process, rural subsistences have progressed towards gradual economic development through the two concepts of agrarian reforms and mechanization of the agricultural sector. This positive trend, with institutional interferences and inefficient rural development policies, the economic downturns of villages have finally provided the ground for the functional development of villages through the implementation of inheritance law, poor management of environmental resources, cross-sectoral supportive policies, and targeted subsidies. This functional development of villages has many symbols, including a strong tendency towards service activities, the prevalence of consumerism, the formation of affiliated villages, a strong market dependence, and so on. It should be noted that in the present research, "inefficient rural development policies" have been identified as a central issue. Research limitations/implications- Low familiarity of the rural population with Persian language (due to the fact that the inhabitants of the study area are Kurds), the high cost of commuting to the villages, the difficulty of establishing trust with villagers, and the lack of welcoming support from institutions related to rural affairs for the researchers in the various stages of the research were the most important limitations of this research. Practical implications- A fundamental revision of rural development policies in view of the changes that have taken place in rural settlements, in accordance with the geographic conditions governing them, is the most important scientific solution of the present research. Originality/value- In the current research, for the first time in Iran, functional changes in villages have been deeply studied through Grounded Theory Method.
