An examination of how farming expertise could be shared and extended, over four centuries. All kinds of knowledge, from traditional know-how to modern science, are socially contingent and the product of an age-long and permanent social struggle. This book unravels the creation and the exchange of agronomic knowledge in rural Europe, from the early eighteenth century up until the end of the twentieth. It explores the spreading of knowing through the lens of "knowledge networks": where did agricultural knowledge come from and how did one learn to run a farm? Who was involved in this process of knowledge exchange? Which strategies and communicative methods were employed and what kind of networks were active? The answers to these questions mirror, as the book illustrates, the inventiveness of the actors on the scene: the creativity of a French naturalist in establishing links with local farmers to stop the circulation of a devastating grain moth, the power of the agricultural press to instill "proper values" into Hungarian farming practices or to shape the identity of the Galician agrarian movement, and the agency of post-war British farmers in selecting their own information, from sources such as lectures to the Young Farmers' Club, visits by public advisors and representatives of commercial firms, and radio programs. From the start of the agricultural Enlightenment, increasingly farmers have been besieged by a growing army of experts, telling them what to do, when and how. In a sense farming has become one of the most patronised professions. But farmers can resist and carve their own path. The chapters here reveal the continuous tensions between science-based agriculture and practice-based farming, between the expert image of an ideal agriculture and the (less known) self-image of being a good farmer. The dominant process, as this book shows, is that of an instrumental top-down transmission of knowledge from "the lab to the field". But between these two poles, complex and flourishing networks developed, functioning as trading zones in which knowledge and experience could be circulated, put to the test, forgotten, altered, rejected - and sometimes imposed.

This book provides the first global analysis of the relationship between trade and civilisation from the beginning of civilisation 3000 BC until the modern era 1600 AD. Encompassing the various networks including the Silk Road, the Indian Ocean trade, Near Eastern family traders of the Bronze Age, and the Medieval Hanseatic League, it examines the role of the individual merchant, the products of trade, the role of the state, and the technical conditions for land and sea transport that created diverging systems of trade and in the development of global trade networks. Trade networks, however, were not durable. The book focuses on the establishment and decline of great trading network systems, and how they related to the expansion of civilisation, and to different forms of social and economic exploitation. Case studies focus on local conditions as well as global networks until the sixteenth century when the whole globe was connected by trade.
