Purpose- This study aimed to analyze the effects of saffron cultivation on the quality of life of rural households in Rostaq Dehestan in Khalilabad county. Design/methodology/approach- This is an applied study based on a descriptive-analytical method used to examine the understudy parameters. The data were collected from 337 sample households based on field studies and by the Cochran sampling method. Then, the data were also collected based on selected indicators and using a household questionnaire. The validity of the questionnaire was evaluated by the university professors of geography and rural planning and agricultural promotion and training. The validity coefficient of the questionnaire was obtained using the SPSS software of 0.85. Kendall's statistical tests and one-way variance analysis was used in SPSS software to analyze the collected data. Findings- The research findings show that Neghab village with a similarity index of 0.48 has the greatest impact of saffron cultivation on the quality of life of the households among the villages of Rostaq Dehestan. On the other hand, the results of the Kendall test confirmed the relationship between saffron cultivation and quality of life with 99% confidence. Moreover, the results of one-way ANOVA showed that the economic dimension among other effective dimensions of the saffron cultivation on the quality of rural households is more pronounced. Research limitations/implications- The lack of access to statistical information when visiting the Agricultural Jihad of Khalilabad, Khalilabad Governorship, the Natural Resources Administration of Khalilabad, as well as completing the questionnaire depending on the issue at the village level are some of the challenges of the present study. Practical implications- According to the research findings, solutions to promote and train the ways for production and productivity of households in this village are recommended for the cultivation of this supra-strategic product (Saffron). Originality/value- The present study is important since it focuses on the impact of saffron cultivation for improving the quality of life of rural households with respect to the income generation process of this product.

Purpose- The aim of this study is to identify and prioritize the obstacles to capacity development in gardening exploitations of the villages of Padena Olya in Semirom County. Design/methodology/approach - The present study has been done with causal - descriptive research method and the data has been completed using questionnaire and interview tools. In addition, 273 samples were chosen (using Cochran formula) from the family farming of Padena Olya Village as the statistical population and it has been completed by the random sampling method. Data analysis is done using both quantitative method, including descriptive and inferential statistics (path analysis and structural equation modeling using Amos Graphic software), and qualitative method, including Atlas software. Findings - The analysis of qualitative findings based on semi-structured interviews and focus groups showed that the main obstacles related to capacity development are of social, economic, and environmental dimensions. Data coding based on the grounded theory also showed the most important obstacles in marketing categories, the environmental obstacles, the obstacles of participation, also and educational and promotional obstacles. Finally, the quantitative data analysis using structural equation modeling, in addition to the obstacles presented in the qualitative model, has estimated production capacities and empowerment as mediating variables in the final model of capacity development obstacles in the study area. The economic obstacles with 0.33 and environmental obstacles with 0.17 have the greatest effect on the lack of capacity development of the exploitations in the study area, respectively. Research limitations/implications - They include the lack of cooperation of relevant organizations in the presentation of information, as well as the low interest of operators to participate in the interview and cooperation to collect the qualitative data which led to an increase in the duration of attendance within the study area, held more group sessions, and thus slowed down the process of study. Practical implications - We propose a plan for increasing government support to gardener in various affaires, such as increasing the share of insurance premiums. It is also advisable to attempt to determine the fair price or the guarantee purchase of the gardeners' products and create cooperatives to manage the sales and marketing of the product to remove the brokers and dealers. Originality/value - The present study stresses the capacity development process of horticulture through identifying and analyzing the effects of obstacles and capacity building and empowerment of farmers. This research explores the hidden variables and the barriers to capacity development in gardening exploitations.

Purpose - Examination and recognition of the processes and mechanisms governing the physical environment of villages and the factors of rural landscape structure have its specific and unique characteristics. These valuable features are applicable in the research process, planning, and plans approaches, as well as in spatial planning to pay for the open environment and rural landscape development. Therefore, the main objective of the research is recognition of the landscape identity components in the tourism villages with valuable texture. These components can be used in the plans and texture restoration of the villages to have a sustainable landscape. Design/methodology/approach- The research is a descriptive-analytic study with the quantitative method by applying a questionnaire that completed by university’s professors and authorities of organs that are related to valuable textures with this important question: what are the landscape identity components and which one of them is so important? By identifying the components, extracting the items and operating the components, collecting and analyzing the data through the SPSS software, performing the ANOVA test and Tukey's test, the components of landscape was identified. These components are readability, vitality, beauty, security and safety, diversity and variety, belonging, accessibility, cultural history, semantics, visual proportions, and physical quality, social, economic, and environmental. Finally, their significance has been determined relative to each other. Finding- The main hypothesis was the importance of the economic (functional-activity) and perceptual components that are based on the findings of the research which ultimately have been ranked in the Tukey’s test table based on the importance of ranking. The ten components in the second column of the components are the most important and the three components in the first column are less important components and two common components are in the first and second columns. The results showed that the economic component (performance-activity) was the most important of all with an average value of 2.61. Within the perceptual components; the historical-cultural component with an average value of 2.55 ranked after the economic component (first rank) and social component (second) as the third important component and the average value of social component was obtained 2.55, so it can be said that the hypothesis was confirmed. According to the results, to have a sustainable perspective for the future, all these components should be considered more prominently in the plans and projects than in the past. While the same research has already not been done on landscape identity in villages, then this research can be the beginning of development and applied research in rural regions.

Purpose - Land subsidence is caused by natural factors and human activities around the world. Fars Province, located in the south of Iran, is subject to land subsidence due to the uncontrolled exploitation of groundwater, causing damages to the population and human settlements and also environmental, social and economic areas. Design/methodology/approach - The present research is descriptive in terms of describing land subsidence in the case study region, whereas it is also analytical as time series analysis techniques based on Radar Interferometry (InSAR) is applied to monitor temporal changes in subsidence in Darab and Fasa Plains, including 470 rural points. Using 8 ENVISAT ASAR images spanning between 2005 and 2010, nine Interferograms were processed. In the study area. Geographic Information System (GIS) is then used to study groundwater level decline at the well locations in a 24-year period (from 1991 to 2015). Findings - The results of the research confirm that there is a significant correlation between groundwater water level decline and land surface subsidence. Time series analysis of the processed Interferograms indicate the mean displacement velocity map, demonstrating the maximum subsidence rate of 25 cm/yr. The InSAR analysis reveal within the study area subsidence rate of 25 cm/year in 24 years period and locally exceeding 30 cm/yr in the last decade. This area of significant subsidence is limited in its spatial extent to the agricultural land and is partly influenced by the large-scale over-exploitation of groundwater resources in the region study. The temporal and areal relationships of subsidence and groundwater level data suggest that a significant part of the observed subsidence in the Darab region is caused by intense groundwater extraction which has led to widespread compaction within the upper parts of the up to 300m. Socioeconomic analysis and the subsidence hazard map show that 105523 people are generally at risk of subsidence, of 65068 who are at high risk. In addition, there are 2679 socioeconomic infrastructures such as public service at risk of damage by land subsidence. Research limitations/implications - Limitation in In SAR data access, especially for long-term data was one of the main limitations in land subsidence research and also in this research. Practical implications - Integrated water resource management and the observed extraction of groundwater could influence the subsidence rate in the regions exposed to land subsidence. Originality/value - This research will be important to provide vulnerability in regions with groundwater overexploitation.
