"The challenges facing agriculture are plenty. Along with the world's growing population and diminishing amounts of water and arable land, the gradual increase in severe weather presents new challenges and imperatives for producing new, more resilient crops to feed a more crowded planet in the twenty-first century. Innovation has historically helped agriculture keep pace with earth's social, population, and ecological changes. In the last 50 years, mechanical, biological, and chemical innovations have more than doubled agricultural output while barely changing input quantities. The ample investment behind these innovations was available because of a high rate of return: a 2007 paper found that the median ROI in agriculture was 45 percent between 1965 and 2005. This landscape has changed. Today many of the world's wealthier countries have scaled back their share of GDP devoted to agricultural R&D amid evidence of diminishing returns. Universities, which have historically been a major source of agricultural innovation, increasingly depend on funding from industry rather than government to fund their research. As Upton Sinclair wrote of the effects industry influences, "It is difficult to get a man to understand something when his salary depends upon his not understanding it." In this volume of the NBER Conference Report series, editor Petra Moser offers an empirical, applied-economic framework to the different elements of agricultural R&D, particularly as they relate to the shift from public to private funding. Individual chapters examine the sources of agricultural knowledge and investigate challenges for measuring the returns to the adoption of new agricultural technologies, examine knowledge spillovers from universities to agricultural innovation, and explore interactions between university engagement and scientific productivity. Additional analysis of agricultural venture capital point to it as an emerging and future source of resource in this essential domain"--

Agricultural yields have increased steadily in the last half century, particularly since the Green Revolution. At the same time, inflation-adjusted agricultural commodity prices have been trending downward as increases in supply outpace the growth of demand. Recent severe weather events, biofuel mandates, and a switch toward a more meat-heavy diet in emerging economies have nevertheless boosted commodity prices. Whether this is a temporary jump or the beginning of a longer-term trend is an open question. Agricultural Productivity and Producer Behavior examines the factors contributing to the remarkably steady increase in global yields and assesses whether yield growth can continue. This research also considers whether agricultural productivity growth has been, and will be, associated with significant environmental externalities. Among the topics studied are genetically modified crops; changing climatic factors; farm production responses to government regulations including crop insurance, transport subsidies, and electricity subsidies for groundwater extraction; and the role of specific farm practices such as crop diversification, disease management, and water-saving methods. This research provides new evidence that technological as well as policy choices influence agricultural productivity.

An investigation into farming practices throughout a period of seismic change. WINNER of the British Agricultural History Society's 2022 Thirsk Prize WINNER of the 2022 CHOICE Outstanding Academic Title Award "This meticulously researched book gives a detailed and authoritative history of agricultural change in the second half of the twentieth century. The book skilfully weaves together the hitherto underexplored individual returns of the Farm Management Survey with oral histories of the farmers who enacted change on the ground to offer an incisive account of the complex technological, political and cultural developments which gave rise to some of the greatest changes in English farming history. It will stand as the key reference point for those with an interest in the history of agricultural change in Britain." Professor Mark Riley, University of Liverpool At the outbreak of the Second World War in 1939 British agriculture was largely powered by the muscles of men, women, and horses, and used mostly nineteenth-century technology to produce less than half of the country's temperate food. By 1985, less land and far fewer people were involved in farming, the power sources and technologies had been completely transformed, and the output of the country's agriculture had more than doubled. This is the story of the national farm, reflecting the efforts and experiences of 200,000 or so farmers and their families, together with the people they employed. But it is not the story of any individual one of them. We know too little about change at the individual farm level, although what happened varied considerably between farms and between different technologies. Based on an improbably-surviving archive of Farm Management Survey accounts, supported by oral histories from some of the farmers involved, this book explores the links between the production of new technologies, their transmission through knowledge networks, and their reception on individual farms. It contests the idea that rapid adoption of technology was inevitable, and reveals the unevenness, variability and complexity that lay beneath the smooth surface of the official statistics.

"The conference was organized by the three editors of this book and took place on August 15-16, 2012 in Seattle."--Preface.

This open access book applies for the first time emerging concepts of socioeconomics to analyse an economic sector, namely agriculture. It considers the rational choices of all actors in the system (just as agricultural economists do) and their cultural preferences and constraints (just as rural sociologists do). Socioeconomic concepts are subsequently used to structure agricultural issues with regard to the three governance mechanisms (hierarchy, markets, and cooperation), and different agricultural systems are presented and compared. The book will be of interest to social scientists with various backgrounds, and seeks to break down the barriers of single-disciplinary thinking.

Forestry cannot be isolated from the forces that drive all economic activity. It involves using land, labour, and capital to produce goods and services from forests, while economics helps in understanding how this can be done in ways that will best meet the needs of people. Therefore, a firm grounding in economics is integral to sound forestry policies and practices. This book, a major revision and expansion of Peter H. Pearse’s 1990 classic, provides this grounding. Updated and enhanced with advanced empirical presentation of materials, it covers the basic economic principles and concepts and their application to modern forest management and policy issues. Forest Economics draws on the strengths of two of the field’s leading practitioners who have more than fifty years of combined experience in teaching forest economics in the United States and Canada. Its comprehensive and systematic analysis of forest issues makes it an indispensable resource for students and practitioners of forest management, natural resource conservation, and environmental studies.
