Book Description
When it first appeared in 1965, The Conditions of Agricultural Growth heralded a breakthrough in the theory of agricultural development. Whereas 'development' had previously been seen as the transformation of traditional communities by the introduction (or imposition) of new technologies, Ester Boserup argued that changes and improvements occur from within agricultural communities, and that improvements are governed not only by outside interference, but by those communities themselves. Using extensive analyses of the costs and productivity of the main systems of traditional agriculture, Ester Boserup concludes that technical, economic and social changes are unlikely to take place unless the community concerned is exposed to the pressure of population growth. In sharp contrast to widely accepted ideas, she shows how population growth may be the main stimulus to agrarian change. In developing this theme, the author identifies successive stages of agriculture, characterized by differences in techniques of cultivation and in social structure and show how they can be explained by differences in population density. This book is of relevance not only to economists, but also to historians interested in the way present changes in agrarian communities parallel those of the past.

Book Description
Low external-input technology (or LEIT) is an increasingly prominent subject in discussions of sustainable agriculture. There are growing calls for self-sufficient agriculture in an era experiencing diminishing returns from reliance upon expensive synthetic pesticides and fertilizers. There are many reasons to support strategies for low external input farming, including a concern for environmental sustainability, increased attention to resource-poor farmers and marginal environments, and the conviction that a better use of local resources in small-scale agriculture can improve farm productivity and innovation. But despite the increased attention to self-sufficient agriculture, there is little evidence available on the performance and impact of LEIT. This book examines the contributions and limitations of low external input technology for addressing the needs of resource-poor farmers. For the first time a balanced analysis of LEIT is provided, offering in-depth case studies, an analysis of the debates, an extensive review of the literature and practical suggestions about the management and integration of low external input agriculture in rural development programmes.

Book Description
This book showcases the power of economic principles to explain and predict issues and current events in the food, agricultural, agribusiness, international trade, natural resources and other sectors. The result is an agricultural economics textbook that provides students and instructors with a clear, up-to-date, and straightforward approach to learning how a market-based economy functions, and how to use simple economic principles for improved decision making. While the primary focus of the book is on microeconomic aspects, agricultural economics has expanded over recent decades to include issues of macroeconomics, international trade, agribusiness, environmental economics, natural resources, and international development. Hence, these topics are also provided with significant coverage.

Book Description
This book presents the basic model of an agricultural household that underlies most of the case studies undertaken so far. The model assumes that households are price-takers and is therefore recursive. The decisions modeled include those affecting production and the demand for inputs and those affecting consumption and the supply of labor. Comparative results on selected elasticities are presented for a number of economies. The empirical significance of the approach is demonstrated in a comparison of models that treat production and consumption decisions separately and those in which the decisionmaking process is recursive. The book summarizes the implications of agricultural pricing policy for the welfare of farm households, marketed surplus, the demand for nonagricultural goods and services, the rural labor market, budget revenues, and foreign exchange earnings. In addition, it is shown that the basic model can be extended in order to explore the effects of government policy on crop composition, nutritional status, health, saving, and investment and to provide a more comprehensive analysis of the effects on budget revenues and foreign exchange earnings. Methodological topics, primarily the data requirements of the basic model and its extensions, along with aggregation, market interaction, uncertainty, and market imperfections are discussed. The most important methodological issues - the question of the recursive property of these models - is also discussed.

Book Description
This textbook addresses the main economic principles required by agricultural economists involved in rural development. The principles of 'micro-economics' or 'price-theory' are of relevance to economists everywhere, but this book reinforces the message of their relevance for rural development by explaining the theory in the specific context of the agricultural and food sectors of developing countries. Hypothetical and actual empirical illustrations drawn almost exclusively from such countries distinguish this book from other economic principles texts that draw their examples almost invariably from industrialised countries, and also from books more oriented to the issue of rural development. The first half of the book deals with the underlying principles of production, supply and demand. These are essential tools for the study and management of the agricultural sector and food markets. In the second half, supply and demand are bought together into a chapter of equilibrium and exchange. This is followed by chapters on trade and the theory of economic welfare. In the final chapter it is shown that much of the material in the earlier chapters can be combined by agricultural economists into a system for analysing and comparing the effects of alternative agricultural policies. The ability of agricultural economics to provide a consistent framework for the analysis of policy problems thus enables it to make a key contribution to rural development.

Book Description
A shocking outline of the interlinked crises in energy and agriculture — and appropriate responses The miracle of the Green Revolution was made possible by cheap fossil fuels to supply crops with artificial fertilizer, pesticides, and irrigation. Estimates of the net energy balance of agriculture in the US show that ten calories of hydrocarbon energy are required to produce one calorie of food. Such an imbalance cannot continue in a world of diminishing hydrocarbon resources. Eating Fossil Fuels examines the interlinked crises of energy and agriculture and highlights some startling findings: The world-wide expansion of agriculture has appropriated fully 40% of the photosynthetic capability of this planet. The Green Revolution provided abundant food sources for many, resulting in a population explosion well in excess of the planet's carrying capacity. Studies suggest that without fossil fuel based agriculture, the US could only sustain about two thirds of its present population. For the planet as a whole, the sustainable number is estimated to be about two billion. Concluding that the effect of energy depletion will be disastrous without a transition to a sustainable, relocalized agriculture, the book draws on the experiences of North Korea and Cuba to demonstrate stories of failure and success in the transition to non-hydrocarbon-based agriculture. It urges strong grassroots activism for sustainable, localized agriculture and a natural shrinking of the world's population. Dale Allen Pfeiffer is a novelist, freelance journalist and geologist who has been writing about energy depletion for a decade. The author of The End of the Oil Age, he is also widely known for his web project: www.survivingpeakoil.com.
