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.

Border security is a major influence on internal sustainability and stability of countries; thus, countries take various military and non-military measures to control their borders and secure them. Residents of border villages and the support they can provide could play a key role in securing borders and bringing profit to them as the main beneficiaries. Therefore, the present study intends to investigate and analyze the roles residents of border villages could play on border security. In order to do so, descriptive-analytical research method is used in both field and library levels and the data are collected and analyzed from 63 local experts in different levels. Findings revealed that, from the point of view of state experts, villagers could be of more significance in economic, social- cultural, political, physical- environmental and defensive- military security. Confirmatory factor analysis on the other hand demonstrated that villagers’ maximum impact on border security could be their political collaboration. Economic, social and physical-environmental factors are in the next level and the defensive-military dimension has the lowest impact for border guards give military aids and the need for military tools and other special conditions makes it impossible for local people. <br />  <br />
