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- Today, tourism has become the largest industry in the world with both direct and indirect socio-economic effects. Given the diverse climatic conditions and limited water resources for agriculture in Iran, among various forms of tourism, tourism in desert areas with a multifaceted approach can narrow the gap caused by environmental constraints and play an important role in the development of different areas such as eastern regions of Isfahan province, which have many tourist attractions. In this research, we try to identify and evaluate land suitability for tourism development in counties located in desert areas of Isfahan province. Design/methodology/approach- In this research, the multi-criteria evaluation (MCE) method was used in the GIS environment. Considering the variety of criteria used, before preparing the final map of land suitability, selected criteria were categorized in different groups with regard to topography, climate, land covers and animal species diversity, environment, hazards, socio-economic aspects. Then, land suitability classes in each of the mentioned groups were identified. In the following step, the maps produced in each of these groups were given to the relevant experts to generate the final map of the land suitability according to the current situation, weigh the selected criteria based on the AHP paired comparison, and implement the results of this comparison in the GIS environment through applying weighted linear combination (WLC) method. Findings - The results of multi-criteria evaluation showed that the study area has highly suitable lands in almost all assessment groups, and there were no specific human and natural constraints in this area. The result of the final land suitability map also showed that 21044 square kilometers of the total area (nearly 30 percent) were ranked in the “very suitable” and “suitable” classes, indicating high capacity and capabilities or minimum natural and human constraints for tourism development in the region. Practical implications- Making use of the capabilities of desert areas in eastern regions of Isfahan province and providing the necessary conditions for tourism development with regard to the particular natural and human conditions of this region can offer the best available, affordable, and effective alternatives in the short term to tackle the current problems based on the principles of sustainable development in these areas. The problems include socioeconomic inequalities between developed and underdeveloped regions of Isfahan province, limited water resources for development of agricultural activities, and low ecological capacity of the region for some activities especially in vulnerable communities.
