Over the last two decades global production of soybean and palm oil seeds have increased enormously. Because these tropically rainfed crops are used for food, cooking, animal feed, and biofuels, they have entered the agriculture, food, and energy chains of most nations despite their actual growth being increasingly concentrated in Southeast Asia and South America. The planting of these crops is controversial because they are sown on formerly forested lands, rely on large farmers and agribusiness rather than smallholders for their development, and supply export markets. The contrasts with the famed Green Revolution in rice and wheat of the 1960s through the 1980s are stark, as those irrigated crops were primarily grown by smallholders, depended upon public subsidies for cultivation, and served largely domestic sectors. The overall aim of the book is to provide a broad synthesis of the major supply and demand drivers of the rapid expansion of oil crops in the tropics; its economic, social, and environmental impacts; and the future outlook to 2050. After introducing the dramatic surge in oil crops, chapters provide a comparative perspective from different producing regions for two of the world's most important crops, oil palm and soybeans in the tropics. The following chapters examine the drivers of demand of vegetable oils for food, animal feed, and biodiesel and introduce the reader to price formation in vegetable oil markets and the role of trade in linking consumers across the world to distant producers in a handful of exporting countries. The remaining chapters review evidence on the economic, social, and environmental impacts of the oil crop revolution in the tropics. While both economic benefits and social and environmental costs have been huge, the outlook is for reduced trade-offs and more sustainable outcomes as the oil crop revolution slows and the global, national, and local communities converge on ways to better managed land use changes and land rights.

In 1965, a group of economists at Harvard University established the Project for Quantitative Research in Economic Development in the Center for International Affairs. Brought together by a common background of fieldwork in developing countries and a desire to apply modern techniques of quantitative analysis to the policy problems of these countries, they produced this volume, which represents that part of their research devoted to formulating operational ways of thinking about development problems. The seventeen essays are organized into four sections: General Planning Models, International Trade and External Resources, Sectoral Planning, and Empirical Bases for Development Programs. They raise some central questions: To what extent can capital and labor substitute for each other? Does development require fixed inputs of engineers and other specialists in each sector or are skills highly substitutable? Is the trade gap a structural phenomenon or merely evidence of an overvalued exchange rate? To what extent do consumers respond to changes in relative prices?
