Sustainable livelihood was introduced in the 1980s as a new approach to rural development to reduce and eradicate rural poverty. Achieving sustainable rural livelihoods is not possible without considering the rural livelihoods assets. Accordingly, the present study aimed to evaluate the impact of livelihood capital on the sustainable livelihood of members of cooperative companies in the rural cooperative project. The present study was an applied and survey research based on purpose and data collection method, respectively. The statistical population included 198 cooperatives managers covered by the cooperative rural project who were selected by proportional sampling. A structured and researcher-made questionnaire was used as a data collection tool. The content and face validity of the questionnaire were confirmed by a panel of experts. Research reliability was ensured using the pilot study and calculating the Cronbach's alpha coefficient. The regression analysis indicated that four social, natural, financial, and physical capitals had the most impact among the five livelihood capitals. پرونده مقاله

The present study aimed to analyze the factors affecting sustainable urban agricultural development in 22 districts of the Tehran metropolis. This causal-comparative study was non-experimental in terms of controlling the studied variables. It was based on a survey strategy and sought to discover the relationships between the dimensions of urban agriculture, as well as those between variables through using a structural equation model. Additionally, the study was correlational research of variance-covariance matrix analysis type because of applying the structural equation modeling to assess the intended conceptual model. The statistical population included all residents in Tehran city who practiced farming in the city environment (urban agriculture) during 2018 under the supervision of the municipalities of 22 districts (n: 240). Further, the sample size was estimated at 145 by considering the table of Bartlett et al. (2001), followed by selecting the participants by using a stratified random sampling method (according to their district). A researcher-made questionnaire was utilized, the validity of which was determined by using content and construct validity. Furthermore, the reliability of the tool was confirmed using Cronbach's alpha, sequential theta, and composite reliability tests. In this study, the urban farmers of Tehran introduced the social, economic, spatial, environmental, and subjective components as important, respectively. Based on the model of the factors affecting the sustainable urban agricultural development in the 22 districts of Tehran metropolis, subjective, economic, spatial, social, and environmental dimensions with the coefficients of 0.24, 0.19, 0.14, 0.09, and 0.08 had the greatest effect on sustainable urban development, respectively. پرونده مقاله

مقدمه: با عنایت به حاد شدن بحران و چالش های آلودگی هوای شهر تهران و با توجه به نقش مدیریت کارآمد فضای سبز شهری در تولید و ارتقای شاخص های فضای سبز، توسعه مدیریت فضای سبز یک ضرورت به شمار آمده و می تواند به منظور کمک به حل بحران آلودگی مورد توجه برنامه ریزان و مسئولان ذیربط قرار گیرد. هدف: این مطالعه با هدف کلی ارزیابی توان های محیطی شهر تهران در راستای برنامه ریزی راهبردی توسعه فضای سبز شهری انجام شد. روش‌شناسی تحقیق: این تحقیق کیفی با بهره گیری از تکنیک دلفی کلاسیک انجام شد و راهبردهای شناسایی شده بر اساس ماتریس برنامه ریزی استراتژی کمّی (QSPM)، اولویت بندی گردید. نمونه مورد مطالعه شامل مدیران، صاحب نظران و کارشناسان مرتبط به موضوع تحقیق در شهر تهران بودند که به صورت هدفمند انتخاب شدند. قلمرو جغرافیایی پژوهش: در این پژوهش محدوده شهرستان تهران به مساحتی حدود 730 کیلومترمربع مورد مطالعه قرار گرفت. یافته ها: برمبنای یافته های مندرج در ماتریس ارزیابی عوامل داخلی به منظور مدیریت پایدار فضای سبز شهر تهران، وجود برنامه های سازمانی میان مدت و بلند مدت جهت اجرای طرح ها و پروژه های توسعه فضاهای سبز شهری، مهم ترین نقطه قوت و عدم انجام مدیریت و برنامه ریزی محلی برای فضاهای سبز مناطق مختلف شهر تهران، مهم ترین نقطه ضعف برای مدیریت فضای سبز شهر تهران، محسوب می شوند. بر مبنای یافته های مندرج در ماتریس ارزیابی عوامل خارجی به منظور مدیریت فضای سبز شهر تهران نیز، اهمیت استراتژیک شهر تهران در کشور و توجه ویژه مسئولین و برنامه ریزان به توسعه شهر در تمام ابعاد از جمله توسعه فضاهای سبز در این شهر مهم ترین فرصت و افزایش آلودگی هوا و تأثیر بر کیفیت فضای سبز با اهمیت ترین تهدید پیش روی مدیریت فضای سبز شهر تهران محسوب می شوند. نتایج: بر اساس ماتریس برنامه ریزی استراتژی کمّی (QSPM)، می توان گفت که راهبردهایی چون نظارت مؤثر بر حسن اجرای قوانین و مقررات در حوزه فضاهای سبز شهر تهران، تهیه و تدوین طرح جامع فضای سبز و مدیریت آسیب های ناشی از عوامل غیر انسانی مانند آفات، بیماری های گیاهی و موارد نامساعد در فضاهای سبز شهری به ترتیب اولویت از مهم ترین راهبردهای موجود برای مدیریت فضای سبز شهر تهران محسوب می شوند. پرونده مقاله

The purpose of this research was to determine knowledge management in the empowerment of the experts of Agricultural Organization in Ilam County of Iran. The statistical population was composed of all employees with the organizational positions of expert or higher in Agricultural Organization of Ilam (N=150). A self-designed questionnaire was used as data collection tool whose face and content validities were confirmed by a panel of experts and whose reliability was estimated to be 0.89 by Cronbach’s alpha. Data were analyzed by SPSS20 in two groups of descriptive statistics (frequency, percentage, mean, standard deviation, and coefficient of variations) and inferential statistics (Spearman test of correlation and multiple regression analysis). Results of regression analysis showed positive, significant relationship of knowledge exchange, knowledge generation, and number of training courses with people’s empowerment so that they, together, accounted for 40% of the variations of dependent variable. پرونده مقاله

The present study generally aimed to analyze the factors affecting the development of the organizing plans related to Zagros nomads among all relevant experts and managers (n=1100).

The study was mainly carried out through a questionnaire, the validity of which was obtained by using a panel of experts. The reliability of the questionnaire was found and confirmed through a pre-test and the calculation by Cronbach Alpha.The statistical analysis was done in a factor analysis method by using SPSS22and AMOS18. The maximum effect on developing the plans of organizing Zagros nomads was obtained in policy making (b=0.59), as well as economic and supportive factors (b=0.56). In addition, marketing (b=0.52), managerial (b=0.46), infrastructural (b=0.44), and educational, extension, and participatory factors (b=0.36) affected the development of the plans positively and significantly, respectively.
