This paper presents a synthesis of 15 success stories in the production, processing, and marketing of high-value food products (HVF) in developing countries in Asia, Latin America, and Africa. High-value food products, such as fresh and processed fruits and vegetables, meats, fish, dairy products, and vegetable oils, are defined as having high intrinsic value or a high rate of value added through processing. Trade in these products has expanded while trade and prices for other agricultural products, such as most staple crops, have stagnated or declined. The growing trade in HVF has prompted policymakers in developing countries to examine more closely how they can expand and diversify their exports of these products. This study explores the technical, organizational, and commercial challenges facing those in HVF export development. It identifies common market and institutional factors that have contributed to the growth and international competitiveness in HVF trade. Particular note is made of the roles of the private and public sectors and of the effect of the policy environment. It examines the effect of institutional coordination on the stages of production, processing, and trade. An annex summarizes 12 case studies of the development and performance of food commodity markets. It includes export of fresh vegetables from Kenya in the 1960s, shrimp from Thailand in the 1970s, and processed tomatoes from Chile in the 1980s.

Human-induced salinisation is a major threat to the world's land and water resources. Inadequate development of irrigation projects, inefficient irrigation, lack of proper drainage, and environmental mismanagement such as the clearing of native vegetation, are responsible for the loss of millions of hectares of agricultural and grazing land, as well as the misuse of scarce water resources. The first part of this book analyses the problem in the context of the world's population, its climate and its land and water resources. It reviews irrigation methods and crop water requirements, the processes of salinisation, and its management. The second part describes irrigated land, dryland and water-resource salinity problems in 11 countries, which contain approximately 70 per cent of the world's irrigated land. In each case study, background data, environmental conditions and past management practices are given to provide an understanding of why salinity occurs in particular places, and of the management methods employed against it.

When waterfowl began to die from selenium poisoning at Kesterson National Wildlife Refuge in California's San Joaquin Valley, considerable alarm arose among environmental and agricultural specialists. This new volume suggests that Kesterson is not a unique problem and the events there offer important lessons for the future. Irrigation-Induced Water Quality Problems uses the San Joaquin experience to suggest how we can prepare for similar problems elsewhere. As one committee member put it, "There will be elsewheres"â€"trace elements and organic contaminants are being concentrated by irrigation in many river basins. This book addresses how the Kesterson crisis developed, how irrigation can endanger water quality, and how economic, legal, and other factors impede our ability to respond to water quality problems. The committee explores how to study these problems, unraveling complex issues and clarifying the varying perspectives of farmers, environmentalists, scientists, and other key figures. This dispassionate analysis of a controversial topic will be useful to policymakers, resource managers, and agricultural specialists and farmers, as well as specialists in hydrology, water quality, irrigation, law, and environmental quality. It will also be useful as a case study in the environmental policy classroom.
