In this study, the relationship between rural deprivation and environmental sustainability was analyzed. The present research is applied in a targeted, applied way and the method is descriptive-analytical. The data gathering tool was a questionnaire, an interview with the locals, a statistical journal of Lorestan province and data from the deputy of rural development and deprived areas. The statistical population includes rural households in Poldokhtar Township (N= 10619). Using Cochran formula and simple random sampling, 400 households were selected as samples. In order to identify the most important indices of deprivation from the exploratory coincidence rating test, One-sample t-test was used to determine the environmental sustainability factors and Finally, Tobit model was used to investigate the relationship between rural deprivation and environmental sustainability. The results show that the highest rate of rural deprivation is related to the economic and cultural deprivation. In the context of environmental sustainability factors, the results show that none of the factors is in stable condition. Water resources, trees, pasture, and pastures are in a state of instability and the only factor that has a somewhat stable status is the soil. Investigating the relationship between deprivation dimensions and environmental instability shows that the economic and social dimension of deprivation has the most impact and relationship with environmental instability. While cultural deprivation of the region, although high has had the least relationship with environmental instability. Therefore, it can be said that to reduce environmental instability and prevent environmental degradation, consideration should be given to the dimensions of deprivation and planning to reduce it.
