the occurrence of landslides in the direction of rivers, especially in the mountainous regions of Zagros range are processes that block rivers and form lake barriers. Della Landslide is an example of such landslide that occurred in the course of Shimbar River drainage and eventually created Lake Shimbar. geoarchaeological field studies performed on this slide using topographic maps, geological, digital model of the area, satellite images and Arc GIS software on the  landslide and  basin lake Shimbar resulted in the identification of the causes of landslides and changes in three stages of the lake. This study eventually rebuilds Paleogeomorphology of landslide area and the lake's dam Shimbar. The results showed that the main cause of the occurrence of landslides were tectonic processes in the region and based on archaeological evidence and the archaeological excavation of the canal, the landslides occurred before 2000 years ago. The formation and changes in the scope and depth of the lake Shimbar in 3 stages blocked the migration routes in area for a long time.

In recent years, one of the main approaches to rural development and increasing the well-being of rural households is the development of rural tourism. Because tourism development can play an important role in the well-being of households as well as in rural livelihoods. The aim of this study was to investigate the effects of tourism on improving the welfare of coastal villages in Chabahar. The present research is a descriptive-analytical approach. The statistical population of rural households is Chabahar (N = 3720). Using Cochran formula and quota sampling method, 280 households in 6 coastal villages with tourist attractions are selected as samples. To analyze the data and to answer the research questions, unlimited exploratory co-univariate test, variance analysis and multivariate regression were used. The results showed that in terms of economic welfare indicators, tourism had the most effects on seasonal employment, income growth, housing development, and local economy mobility. In terms of social welfare indicators, tourism has the most impact on improving leisure time, changing lifestyle and lifestyle, developing health facilities, and increasing the sense of belonging to local people. Also, the results showed that tourism in the villages of the study area had significant effects on the economic and social well-being of rural households, but compared with social indicators, tourism had the most impact on economic well-being and its indicators. In line with the findings of the research, suggestions were made regarding the development of rural tourism and the welfare of rural households.

Population growth and the need for economic and social services have accelerated the demands for land and its manipulations over the recent decades. The contribution of policies and interventions of different stakeholders in land change is not adequately addressed in previous studies. This research, therefore, aims to examine the role of key stakeholders, and their policies in land-use change in the study area. In doing so a total number of 20 interviews with senior experts and informants from 13 local organizations were conducted to collect qualitative data on the form, process and cause of land-use change in the area. Atlasti software was used to analysis the interviews' data. Furthermore, Social Networks Analysis (SNA) and questionnaires were used to map the trust among the stakeholders and also the role of their policies and program on land-use changes from the perspective of other stakeholders. The results show that the policies and interventions of the municipality are playing the most significant role in land-use change via disregarding and violations of roles and related for individual illegal benefits. Additionally, departments of agriculture, rural councils are among the most trusted agents in land use governance and management. Furthermore, water shortage was the most important reason pointed out by the many interviewees for conversion of farmlands to other uses. A part from water shortage, some other reasons such as: lack of governmental support for farming, strict official constraints and difficulties in providing amenities for gardens, expensive agricultural inputs, land price increase, immigration, corruptions in local organization are identified as drivers of rural land-use change.

The purpose of this study is to present a model of religious tourism based on the art of taziyeh in Kashan based on structural equation modeling, based on a mixed exploratory approach. In the qualitative part, the phenomenological method was used and in the quantitative part, the descriptive method, correlation based on structural equations was used. The statistical population of this research in the qualitative part included professors and experts in tourism and condolence in Kashan, which was obtained after 15 saturated interviews. In order to evaluate the validity of qualitative data, structural, external, descriptive and interpretive validity were used and in order to evaluate the reliability, the three approaches of Rao and Perry (2003) were used. The results of qualitative research were extracted from 11 economic, strategic, development, research, organizational, technical, content, environmental and advertising dimensions. After examining the extraction of components, the quantitative part of the research was examined. Factor and content validity were used to evaluate the validity. The reliability of the questionnaire was used from Cronbach's alpha, which had the necessary reliability. Available was selected. The data obtained from the questionnaires were analyzed at two levels of descriptive and inferential statistics, including structural equations, through SPSS 22, LISREL 18.9 and Warp PLS 5 software. Findings showed that the most impact was economic dimension (impact factor 0.86) followed by cultural dimension with (0.79) and strategic dimension with (0.78).
