Purpose- Food security (FS) is defined as sustainable access to safe and nutritious food for a healthy and active life. The present study was designed to investigate and determine FS status of rural households and the relevant influential factors. It was conducted on 432 rural households in six subdistricts of two districts of Sarpolzahab, West of Iran, in 2016. Design/methodology/approach- The samples were selected using random cluster sampling, and FS status was assessed using United States Department of Agriculture (USDA) household FS questionnaire. Therefore, both socio-economic questionnaire and the household FS questionnaire were completed during a face to face interview. Data were analyzed using the statistical software package SPSS-22. Chi-square, Mann-Whitney, Kruskal-Wallis, and forward multiple logistic regression were used for data analysis. Findings- Prevalence of food insecurity (FI) in all of the surveyed households was 65.3%, and household FS status between the subdistricts had a significant difference (P< 0.01). The results of the study showed that the prevalence of FI in the subdistricts of Posht-Tang and Sarab (83.3% and 76.4%, respectively) was higher than other subdistricts. Number of household’s members, land ownership, education of household’s head, activity status, and household’s income had significantly relationship with household FI (P< 0.01). Practical implications- The high prevalence of FI is a major threat to the abnormal utilization of environmental resources in this realm. Therefore, given the impact of horticultural activities and diverse cultivation on household FS, macro and regional policies should be provided to increase the diversity of products through agroforestry and intercropping. Original/value- This research presents the basic information on the FS status of rural households in Sarpolzahab and some related socio-economic factors the results of which can help planners and managers to implement interventions to improve the FS and welfare of rural households.

Purpose - Niche tourism refers to how to use a particular tourism product tailored to the needs of a particular segment of the market. Places with niche tourism products are able to achieve a high position and consolidate their future position in the tourism market. This type of tourism helps distinguish tourism products by creating an image of the destination and helping compete in the increasingly crowded environment of the tourism market. This paper investigates and analyzes the niche tourism attractions in Ghaleh Rudkhan tourist destination village using activity-based segmentation, the attitudes of the host community in dealing with niche tourism development, and the ability to implement tourism projects and socio-economic factors influencing tourism development in the region, which eventually offers solutions to overcome the current and potential challenges in the study area. To collect the data, interview-based methods, focus group interviews, individual observations and analysis of the documents obtained from different sources were used. Design/methodology/approach - A questionnaire was designed and distributed among 383 tourists and 190 rural employees. The data of this study were mainly evaluated using thematic and content analysis methods. Besides, we have also introduced the niche tourism potentials and tourism activities in the region. Finding - The results show that thanks to the economic and social opportunities, local communities support tourism development in Ghaleh Rudkhan; however, the challenges associated with tourism marketing, event management, uncertainty of private sector investors and environmental issues must be addressed through a participatory approach.

Purpose-Local non-governmental organizations (NGOs) being regarded as the clear representation of the participation of people, pave the way for fulfilling the objectives of sustainable development. The main goal of this study is to investigate the circumstances and consequences of local NGOs in empowering rural women in protecting the environment of Roshtkhar County (One of the southern Counties of Khorasan Razavi province). Design/methodology/approach- The data needed for this study have been obtained through semi-structured interviews with a purposive sample of the founding boards and active members of NGOs (n =27). Findings-The results of the current study that utilized the conventional coding process indicating that in the villages studied, NGOs protect and improve the environmental performance and lead to the economic empowerment of the rural women. Research limitations / implications- Similar to other rural research, this research has encountered some general problems that have plagued other rural research in the country. Statistical problems and lack of cooperation and justification of Governmental organizations Originality/value- As the results of most studies show, despite some difficulties and difficulties for the growth and development of such institutions in the country, most of them have an important role in women's empowerment. Although very little research has been done in the country, no research has been done in the study area.

Today, the issue of sustainable development has become one of the most important global issues and has become the focus of attention and human attention in the economic, social, and environmental perspectives. Various human activities, as well as the development of industries and the expansion of urbanization with waste and wastewater, have contaminated soil. Different methods are available to clean up the soil about economic issues. One of them is the electro remediation method, which is often applied in low-permeability fine-grained soils and is successful as a greenhouse effect in reducing the toxicity of heavy metals and is a new and developing approach for organic pollutants. This paper will be presented the effective parameters, the strong points as well as limitations, to clarify the basic concepts in the electro remediation process. Conduct experiments with the three-dimensional arrangement of electrodes instead of the linear arrangement of electrodes could be more practical. Using geosynthetic electrodes to prevent corrosion of metallic electrodes, combining the electro remediation process with other designs and different operational modes, and overcome to the problem of reducing the electro-osmosis flow and reverse electro-osmosis flow with pH control are methods to enhance the rate of removal of pollutants from soils.
