  • The effects of environment and technology on agricultural export

    The impact of environmental policy on international trade has received a great deal of attention over the decades. Theory predicts that the relative level of a country's environmental policy, technology, and factor endowments will jointly determine international trade and specialisation. This study develops alternative empirical models of export shares to evaluate the effects of technology and ...

  • The Effect of Off-farm Work on the Intensity of Agricultural Production

    Changes in agricultural production methods have been associated with environmental pressure and a loss of natural habitats. This paper explores the extent to which farmer participation in off-farm work (an increasing phenomenon in most developed countries) changes the intensity of agricultural input use focusing, in particular, on fertilizer and crop protection product use. A sample selection ...

  • Transdisciplinary research for a sustainable agriculture and food sector

    Research in agriculture has strongly focused on discipline-oriented, natural science-based approaches to increasing production with success measured by short-term, neoclassical economic evaluation. This strategy has contributed to impressive increases in food production over the last half century. Growing concerns include environmental impacts, changes in rural communities, and distribution of ...

  • Performance analysis of a co-gasifier for organic waste in agriculture

    Background:Agricultural waste has been proposed as an alternative energy resource to meet fossil fuel crisis, green house emission, and other environmental impacts worldwide. In Iran, rice husk and bagasse are main resources of biomass which can be used to produce syngas. This paper deals with a simplified model of combined gasification of coal and biomass processes considering chemical ...

  • The challenge of integrating EU and Turkish agricultural markets and policies

    This paper addresses the potential consequences of a political and economic integration of EU and Turkish agriculture and evaluates the resulting challenges. Simulation models reveal declining agricultural prices for Turkey in the case of market integration with the EU. This would lead to less production, more consumption and Turkey becoming a net importer of agricultural products. Resulting ...
