The Main Objective of the Present Study was to Investigate Mechanism of Rural Tourism with emphasis on the Natural tourism in the village of Hyderabad in ilam County. The Present research was applied type based on the goal, in terms of the Nature it was quantity research and in terms of the method of Collecting data was a Survey research. The Population of this study Consisted of three groups of expert(N=40), Rural housholds (N=110) and Touirists. For Selecting Sample, in the Case of  the first groups the Census method eas used and for Tourists Population by using Simple Random Sampling method 100 people were Selected and altogrther 250 People were Studied. Main Instrument of gathering data was questionnaire that its Validity was Confirmed by Experts Panel of ilam universiry and Islamic azad University of ilam branch and Expets of Tourism. Cronbach alpha Coefficient was used to determine questionnaire reliability and its value was equal to ./96. For dara analysis, descriptive statistics such as frequency, percentage, mean, standard deviation and coefficient of variation was used. For analytical statistics, factor analysis was used. The Resuls of Factor analysis Showed that in Natural Dimention, Infrastructural- Cultural mechanisms with the percentage of (25/55) was the most important mechanism of Rural Tourism Development.

Environmental dimensions can be used as indicators of urban quality of life due to their potential contribution to subjective well-being. The environment is constituted by the interacting systems of physical, biological, and social elements interrelated in various ways, individually and collectively. This study aims to uncover qualitatively whether these two environmental elements, namely social and physical factors, are indeed predictors of subjective well-being and reliable indicators of quality of life in cities. The study presents and tests a model that examines a matrix of cross-effects between social and physical indicators with subjective well-being. Data are obtained through an expert survey in the city of Tehran. In this approach, a group of urban planners undertakes the effect of social and physical components on subjective well-being. First, the existing literature is studied, and the related components are identified. Then, some interviews are made, and the cross-section analysis effects are extracted in a cross-effect matrix. As the finding revealed, among physical factors, percapita and spatial justice can have the highest impact on subjective well-being in Tehran. This was followed by access to urban transportation networks depending on their type, quality, and amount. Also, commute, neighborhood, housing, and job satisfaction were predictors of subjective well-being. Among social factors, spending leisure time, continuous social interactions, and health status impact subjective well-being. 

Environmental risks and conflicts in the framework of the relations between countries and subsequently their role-playing in interaction and collaboration or conflicts and struggles between political actors especially in the level of states have reproduced serious discussions and disputes on the environment, security, and power which are interpreted as environmental geopolitics or ecopolitics by modern political geography. Geographically, the Persian Gulf is a semi-enclosed sea that has a very low capacity of self-dredging in comparison to that of high seas; hence, it retains the pollutants for longer periods of time. Some of its environmental problems arise from the various activities of the people residing along the northern and southern shores. If the situation is exacerbated by the factors such as oil and its subsequent pollutions, militarism and its subsequent destruction, desalination of seawater, and the construction of artificial islands, one can conclude that regional convergence between the countries neighboring this body of water in the process of bioregionalism would be of an essential necessity. According to the research findings, states acting in the geopolitical region of the Persian Gulf to produce power, security and to sustain them, from one hand, and to protect this shared aquatic ecosystem in the event of sustainable development, from the other hand, should mobilize all collective cooperations and operationalize the bioregionalism in regional and supranational scales.

Livestock and poultry production and supply is one of the significant food sectors in which more production can lead to a decrease in dependence on exports and earning foreign exchange. Poultry farming is a vital industry for sustainable food supply in all countries. In this research, intelligent applications and solutions in the poultry industry are identified and prioritized using the simultaneous evaluation of criteria and alternatives (SECA) methodbased on criteria representing the sustainable development. Analysis showed that eighteenprincipalfieldsof intelligent solutions are identified in the poultry industry. The weights obtained for sustainable development criteria based on the SECA method are economic (0.351), social (0.3383), and environmental (0.3065) in order of value. Economic sustainability should be most importantinimplementing smart solutions-based projects in the poultry industry. One of the main challenges of the agricultural sector, especially the poultry industry, is traditional production utilization which leads to the overuse of land capacity. Also, the globalization trends, climate changes, moving from a fossil fuel-based economy to an environment-based economy, competition for land, freshwater, and labor shortage have led to more complications in supplyingnutrition. Considering the potential of smart solutions in realizing sustainable development objectives, it is suggested to focus more on the environmental aspects of poultry industry projects.
