Most of the typical international agricultural trade research evolves around traditional topics such as the impact of various trade policies including tariffs/taxes on the flow of agricultural trade among countries and on resulting agricultural prices, or the impacts of preferential, regional and global trade agreements on agricultural productivity and welfare implications of such measures on different interest groups. Yet, a variety of issues emerges as potentially more relevant and constraining for the future of global agriculture. This book is dedicated to such issues, on the margin at the moment yet obviously most important for the future of agriculture, globally and locally.
