Problem statement: As trade agreements decrease tariffs throughout the world, other barriers to trade emerge. These Non-Tariff Barriers (NTBs) can be just as troublesome as tariffs for exporting countries. NTBs include any of a number of hindrances that restrict the ability of companies to export. NTBs may now have a greater impact on trade than tariffs.
Approach: In contrast with previous research, we used a gravity model to estimate the trade effect of non-tariff barriers imposed by importer countries on pistachios, raisins and shrimp exported by Iran.
Results: NTBs had a negative impact on pistachio and shrimp exports and their effect was greater than that of tariffs; raisin exports were unaffected by NTBs.
Conclusion/Recommendations: The export and the world demand for agricultural products increasing focusing on quality, packaging, labeling and standards of products. Policy makers in countries that export agricultural products, such as Iran, must consider these characteristics when designing their programs. Therefore, if Iran builds up-to-date production systems, it will increase its exports of agricultural products.

  Sustainable agriculture has defined and described in many ways. Despite the diversity in conceptualizing sustainable agriculture, there is a consensus on three basic dimensions of the concept, namely, ecological soundness economically viable and socially acceptable. The dimensions of ecological soundness refers to the preservation and improvement of the natural environment. Environmental issues emerge from the human use of natural resources. Farmers' decisions to adopt a new agricultural technology depend on complex factors. One of the factors is farmers' perception. The objective of this study was to investigate perceptions of paddy farmers towards applying sustainable agricultural technologies and to identify factors influencing their perceptions. The results of the study show that farmers had good perception about sustainable technologies such as diversification and rotation, application of manure but in general, they preferred modern technologies to local ones. They perceived agrochemicals as the best means to combat against pests and to increase rice production. Their perception of intangible impacts of modern technologies was weak. It was found that there should be a relationship between a numbers of socio-economic factors, such as human capital factors, information sources use, extension participation and landholding size and the perception towards selected sustainable agricultural technologies. Also, educational level, contact with agricultural experts and extension participation were best predictors of their perceptions.

  Problem statement: One of the main targets of Iran’s economic development plans in agricultural sector during the recent years was to augment agricultural exports and establish a positive trade balance in this sector. In this research the impact of macroeconomic indicators of Iran and its 20 trading partners on Iran’s agricultural trade balance had been investigated. Approach: The ARDL approach was applied during the period of (1960-2005). Results: The domestic real income had the highest effect on the agricultural trade balance relative to other indicators both in the short-and long-run period. On the other hand, domestic money supply and foreign real income had the lowest effect in long-run and short-run respectively. In addition, real exchange rate had the positive impact on trade balance indicating that the depreciation will improve trade balance. But this is not a robust political instrument for establishing long-run equilibrium. Finally, the ECM results implied the fairly high speed of adjustment to equilibrium. Conclusion: The policies that tend to increase domestic income should be planned in such a way that the increased purchasing power of people will be directed to domestic goods rather than foreign goods.
