Abstract
Sustainable agriculture, as a managerial philosophy has risen to meet environmental, economic and social complications. Agricultural as a source of information plays an important role for the achievement of sustainable forms of agriculture. In fact, conventional system cannot accomplish sustainability in agriculture. The objective of the study was to identify the most appropriate mechanism to support dimensions and policies of sustainable agriculture that used a descriptive-correlative design. The population of this study consisted of faculty members of agricultural education, head in provinces and specialists of deputy of agricultural and farming system in the Ministry of Agriculture in Iran. A sample consisting 87 respondents was selected through simple random sampling. The instrument used to achieve objectives of the study was a questionnaire by reliability 0.86. Findings indicate that Iran's sustainable agricultural mechanisms are not favorable and the system does not pay enough attention to them. These conditions necessitate rethinking of mechanisms to accomplish sustainable agriculture. When examining the results of the Canonical correlation analysis, it reveals that the Wilks Lambda test was significant at 0.01 level. It indicates that the first squared Canonical correlation (R2 C (1)) was statistically significant. Based on the Canonical correlation analysis, on the predicator variables set, assets of sustainable agriculture development, supportive organizations toward sustainability, content of sustainable agriculture extension and professionals of sustainable agriculture extension, loaded highest on Canonical function one and had the most impact upon policies and dimensions of sustainable agriculture.
Highlights
In Iran, like other developing countries, agriculture is one of the most important economic sectors and comprises a considerably high percentage of production and employment
It seems that sustainable agriculture is more than a shift in farming practices rather it must be focus on raising consciousness[33]
In section five and six were asked respondents to indicate their degree of agreement regarding the ability of extension system to accomplish dimensions and policies of sustainable agriculture, respectively
Summary
In Iran, like other developing countries, agriculture is one of the most important economic sectors and comprises a considerably high percentage of production and employment. Social competence is not required as complex socio-organizational issues (e.g., land-use regulations, power structures, conflict resolution mechanisms) are neglected or reduced to a technical level[8, 23] It seems that with this system we cannot accomplish to sustainability, because of the traditional roles of transferring and disseminating of agricultural technologies are proving insufficient in today's global context[35]. The changes in the working environment, which be called as forces of change, vary in nature and scope, i.e., they could political, technical, economic or social The effects of these forces of change are very important in dynamism of extension system toward sustainability, since the extension systems are directly or indirectly affected by the changes and, in response, must make internal and external adjustments in order to keep functioning at the same or higher level of efficiency to accomplish sustainability. Based on the aforementioned pattern, the main purpose of this study was to identify the most appropriate extension mechanisms to support dimensions and policies of sustainable agriculture in Iran context
