Book excerpt: First published in 1982. Until the nineteenth-century the history of agriculture was the history of mankind but it has not perhaps received the wide attention that this importance justifies. In this study, the author reviews for the student of agricultural history successive attempts to describe and explain agricultural changes that are not specific to a limited area or a particular time. In a sense The Dynamics of Agricultural Change is a systematic historical geography of agriculture. Some of the models the author explores have been developed within agricultural history; some, drawn from other disciplines, can be applied fruitfully to it. What is the relationship between population growth and agricultural development? Between environmental changes and those in agriculture? What was the effect of the industrial revolution? And has there been an agricultural revolution? This book suggests to university students of economic history, historical geography and agriculture, a number of stimulating ways of interpreting and reinterpreting agricultural history.
