Analysis of the effective factors on dimensions of sustainable agricultural development in Khorasan Razavi province, using seemingly unrelated regression equations

Sustainable agricultural development is a multidimensional concept, has become increasingly important over time. Therefore, identifying the factors affecting each of the dimensions of sustainable agriculture is necessary for proper planning. In this paper, an attempt is made to determine the factors affecting the four dimensions of sustainable agricultural development in Khorasan Razavi province by using seemingly unrelated regression equations (SURE) and using a sample of 398 farmers selected by two-stage random cluster method. Data obtained from the completion of the questionnaire in 2019. The results show that, the average indicator of social sustainability is 0.55, environmental sustainability is 0.47, economic sustainability is 0.41 and political sustainability is 0.32. Also, there are significat correlations between variables of participation in training courses, interest in agriculture and job satisfaction with the components of agricultural sustainability. There is significat correlation between membership in farmers' cooperative with political stability, land ownership with social and political components, and land integration with economic component of sustainability. Accordingly, it is suggested that extension trainings in the field of sustainable agriculture be developed. According to the priority of managerial sustainability, investment in agricultural infrastructure, improvement of decision-making methods, development and strengthening of agricultural organizations, development of support laws and the development of sustainable employment be on the desicionmakers. In addition, developing a proper marketing system with the aim of preventing waste and reducing production costs will ensure the stability of farmers' incomes.
