In this research, the development of cross-border cooperation (CBC) to study the factors and stimuli affecting the stability of the ::::union:::: in the border regions were discussed. The aim of the present study, functional and combination method (qualitative and quantitative) is. The data-gathering tool was a questionnaire and interview. The statistical community included various experts in the fields of political science, geography, economics, sociology, law enforcement experts, governorate and governorate in Sistan and Baluchestan province. Using a targeted sampling, 70 experts were selected. For analysis of data, descriptive tests and binary logistic regression model (LM-Newton-Marcard-Raphson method) were used. The results showed that in the area of planning for unity in Sistan and Baluchestan except for the determination of the right of the Hirmand River in the Sistan region, which was concluded with the country over a period of time, the plan was not approved or implemented, and among the five factors Economic, social, cultural-religious, institutional-structural and political security, three economic factors (0.478), political-security (0.473) and cultural-religious (0.363) have the most effect on the stability of unity of border regions in Studied area. The results of this study can be used to develop border cooperation cooperation and coherence stability in different border regions of Iran.
 

Today, due to climate change, natural hazards and how to deal with them are among the most important concerns of researchers in environmental planning and crisis management. The purpose of this study is the assessment of the potential flood risk in Sarbaz drainage basin. For this purpose, the databases including elevation, slope, geological characteristics, soil characteristics, precipitation, vegetation, land use, and vector layers of the main channel, streams and drainage densities of the basin were used. By using the questionnaire and experts' opinion as well as hierarchical analysis, the weight of influences of each layer was calculated in basin flooding. Each of these layers was classified based on the flood potential from low to high-risk scale and eventually merged with the weighted overlay model in Geographic Information System. The results showed that main streams, land use, and precipitation are the most important components in the flood risk of the Sarbaz river drainage basin. From the total area of the Sarbaz basin, only 0.5% has a high to extremely high flood potential, and the central areas of the basin have the highest potential for flood due to topography and special hydrographic conditions. In addition, the main river basin districts towards the outlet of the basin as well as parts of the margins of important sub-streams have the highest flood potential. Despite the limited area of the high-risk zone, due to population density and agricultural land, the importance of this area is very high in crisis management.

Tourism plays an important role in rural development. Tourism while enhancing the rural development process through diversification of economic activities, maintaining social integrity, environmental protection, and positive spatial-physical changes in rural settlements can increase the quality of life in rural areas. Due to the importance of this issue, in the present study, the effects of tourism on improving the quality of life of rural settlements were investigated. The present research is descriptive-analytical in terms of purpose and method. The data collection tool was a questionnaire and interviews with rural households. The statistical population includes rural settlements on the shores of the Oman Sea in the south of Sistan and Baluchestan province, the two coastal cities of Konarak and Chabahar (N = 4855). Using Cochranchr('39')s formula and quota sampling method, 356 samples in 12 villages that had tourist attractions were selected as a sample. Descriptive tests, analysis of variance and path analysis model were used to analyze the data and answer the research questions. The results of analysis of variance showed that tourism has a good linear relationship with increasing the quality of life in rural settlements of Konarak and Chabahar. So that according to the route analysis model, rural tourism has different and favorable effects on economic, social, environmental and physical-spatial indicators and the value of p of all Lamda parameters in the above model indicates the confirmation of all regression relationships. Among the four dimensions, tourism development has had the greatest effect on the economic dimension of quality of life and the least effect on the social dimension of quality of life in rural settlements.
