The Study of The Environmental Sustainability of Rural Housing in Lorestan province, Iran
The present study has assessed the environmental sustainability of rural housing in terms of quantitative and qualitative indicators, according to the latest information resources from the Statistical Center of Iran and the Housing Foundation of Islamic Revolution, together with analytical and technical methods. Data collection was conducted using TOPSIS method, the coefficient of dispersion, and cluster analysis. Results from the TOPSIS method, which was used for analyzing the application of environmental indicators of rural housing, show that the CLi values of this index in the cities of Dorood and Aligoodarz are 0.461376 and 0.103033, respectively. Delfan, Azna, and Khoramabad, as wealthier cities, are next in the ranking, following the city of Dorood. The CLi values obtained from environmental measures of rural housing reveals the existence of gaps and divergence between the cities of Lorestan province. Coefficient of dispersion indicators show that the ratio of housing with appropriate sewage system (wastewater) by a factor of 1.153702734 has the highest coefficient of dispersion and the ratio of housing with appropriate sewage system (toilet) with a coefficient of determination of 0.02354327 has the lowest coefficient of dispersion among the indicators. The results show that the environmental indicators in the cities such as Aligoodarz, Poldokhtar, and Koohdasht, where there are livestock activities, are in more unsustainable situation, as compared to other cities of the province.
