Agriculture & related industriesApril 2000History of Farming Systems Research
by Edited by Michael P Collinson
Farming Systems Research (FSR) may be defined as a diagnostic process, providing a collection of methods for researchers to understand farm households and their decision-making. Its applications use this understanding to increase efficiency in the use of human and budgetary resources for agricultural development, including research, extension and policy formulation.This book provides a detailed history of FSR. While it includes the application of FSR to developed country agriculture, its main focus is on FSR in its original role, with small-scale, resource-poor farmers in less developed countries. There are some 40 contributions from nearly 50 contributors from 20 countries, illustrating both the diversity and coherence of FSR. The book was initiated by the then International Association for Farming Systems Research and Extension (now International Farming Systems Association) and developed with support from FAO. It provides a wealth of information and insights for all concerned with agricultural development.

EconomicsNovember 1998Agriculture and World Trade Liberalisation
Socio-environmental Perspectives on the Common Agricultural Policy
by Edited by Michael Redclift, Joseph Lekakis, George P Zanias
The impact of free trade on the environment and the employment of environmental policies as non-tariff protectionist policies are topics which are currently receiving a great deal of attention. Proponents of freer trade insist that, by leading to higher growth rates and per capita incomes, trade increases the demand for environmental quality and helps poor countries escape the poverty-generated pollution trap. The purpose of this book is to discuss the current and future issues surrounding agriculture and its relationship to trade, sustainability and the environment. It is based on selected papers from an international conference entitled ‘European Agriculture at the Crossroads: Competition and Sustainability’ held in Crete in 1996 and further updated with the European Commission’s Agenda 2000 in mind. Written by leading authorities from Europe and the USA, this book is essential reading for researchers and policy makers in agricultural economics, rural sociology, the environment and European studies.

The environmentMay 1997Phosphorus Loss from Soil to Water
by Edited by H Tunney, P C Brookes, A E Johnston
Phosphorus is an essential element for plant growth and its input has long been recognised as necessary to maintain profitable crop production. However, phosphorus inputs can also increase the biological activity of surface waters and this can lead to the destruction of such aquatic ecosystems. Advanced eutrophication of surface water leads to problems with its use for fisheries, recreation, industry and drinking, due to the increased growth of undesirable algae and aquatic weeds, and oxygen shortages caused by their death and decomposition. It is therefore important to have a good understanding of the causes and mode of phosphorus loss from soil to water, to enable the problems to be controlled and managed. This book has been developed from an international workshop held in Ireland in late 1995. It is the first comprehensive consideration of the topic, and many leading researchers in the area have contributed to it. It is essential reading for all soil scientists and freshwater biologists, as well as for environmentalists, ecologists and agriculturalists concerned with sustainable land management and pollution. The book is also recommended to fisheries managers, fertilizer manufacturers and biologists working for water utilities.

Animal breedingNovember 1996Principles of Poultry Science
by Edited by S P Rose
Poultry are farmed and are important sources of protein throughout the world. All students of agriculture are likely to be required to study poultry science to at least an introductory level. However, hitherto there has been no suitable textbook serving the needs of students taking a general introductory course in poultry science. This book aims to fill this gap. It explains the science underlying the productive processes of growth, reproduction and incubation. The applications of nutrition and breeding techniques are described. The book covers all the commercially important poultry species, including turkeys, quail, guinea fowls, ducks and geese, but the main emphasis is on the domestic fowl. The overall purpose is to provide the student with an understanding of the characteristics and physiological responses of domesticated poultry, with particular reference to production. The emphasis is on modelling responses rather than on biochemical and hormonal processes. The author stresses basic concepts and models, rather than practical production systems, so that the book should have worldwide applicability. The book represents a key text for degree and advanced diploma courses in agriculture.

Animal husbandryOctober 1998Response in the Yield of Milk Constituents to the Intake of Nutrients by Dairy Cows
by P C Thomas, David E Beever, P J Buttery, J C MacRae, J D Oldham. Edited by Geoffrey Alderman.
This report reviews the energy and protein requirement systems for dairy cows currently used in Britain and presents a new approach, along with the outline of a model for its implementation. Current systems give little consideration to the responses of the animal to changes in the nutrient supply, or to interactions between dietary constituents in their effects on digestion and metabolism. Neither do they predict any effect on the partition of nutrient use between milk and body, or changes in the yields of milk fat, protein and lactose, which determine the commercial value of the milk. Therefore the systems, although not inaccurate, lack relevance to the current needs of UK milk producers. Models which embody concepts of nutrient supply and utilization are reviewed and their development as viable alternatives is considered. It is concluded that a new diet formulation system for dairy cows should aim to predict voluntary feed intake, the partition of nutrient use between milk production and tissue deposition, and the short and long-term of effects of nutrition on fat, protein and lactose yields. The physical and biological characteristics of the cow must also be recognized and incorporated into any model for response prediction. The report is also published in Nutrition Abstracts and Reviews - Series B: Livestock Feeds and Feeding. It is an authoritative review for advanced students, research workers and advisors in animal nutrition and in dairy science and technology.

Limnology (freshwater)December 2004Organic Phosphorus in the Environment
by Edited by Benjamin L Turner, Emmanuel Frossard, Darren S Baldwin
Organic phosphorus is involved in almost every biological process. Organic forms of phosphorus often dominate in soils and aquatic systems and many organisms possess complex mechanisms enabling them to access phosphorus from organic compounds. However organic phosphorus remains the most poorly understood aspect of the global phosphorus cycle. This book brings together the latest research and opinion on the biogeochemistry of organic phosphorus from a wide range of disciplines and focuses specifically on the characterisation and transformations of organic phosphorus in terrestrial and aquatic systems. It examines analytical procedures for the chemical characterization of organic phosphorus in environmental samples, processes regulating organic phosphorus in the environment, and integration of the process at the ecosystem level. Ecological, chemical, microbiological and analytical aspects are explored. Written by a team of leading experts, the book will provide an invaluable reference for all those interested in organic phosphorus.

Medical parasitologyOctober 1998Sexually Transmitted Infections and AIDS in the Tropics
by Edited by Om P Arya, Charles A Hart
Sexually Transmitted Infections (STI) are a major public health problem both in their own right and because of their link with HIV infection. This has elevated their control to an absolute priority throughout the world. In developing countries, which account for approximately 75% of the easily curable STI, as estimated by the WHO, and where sexually transmitted HIV infection has reached epidemic proportions, the need is most acute. Here AIDS is claiming hundreds of thousands of lives and will continue to do so for the foreseeable future. In addition, because of inadequate resources, the sequelae of STI (e.g. infertility and some cancers) contribute greatly to ill-health in the tropics. This book written by acknowledged experts working or with experience in tropical countries, gives clear, concise and up to date knowledge and understanding on all aspects of Sexually Transmitted Infections. It should be useful for all those involved in the appropriate management and control of STI in various settings, ranging from peripheral and rural and urban health care centres to large hospitals. It will also be invaluable for students of tropical medicine, medical microbiology and genito-urinary medicine.

BiotechnologyDecember 2003Intellectual Property Rights in Agricultural Biotechnology, 2nd Edition
by Edited by Frederic H Erbisch, Karim M Maredia
During the past twenty-five years, biotechnology has revolutionized agricultural research. The enormous potential, together with a landmark decision by the US Supreme Court to allow the patenting of genetically-engineered organisms has encouraged private sector companies to invest in agricultural biotechnology research programmes. This has contributed to a rapid growth in interest in intellectual property rights as applied to this subject.The first edition of this book was published in 1998. Now fully revised and updated it presents definitive information on intellectual property law in a simplified form (with a minimum of legal jargon). New chapters have been added which cover plant variety protection and farmers rights, and additional case studies.

Global warmingJune 2014Climate Change Impact and Adaptation in Agricultural Systems
by Edited by Jurg Fuhrer, P J Gregory.
The focus of this book is future global climate change and its implications for agricultural systems which are the main sources of agricultural goods and services provided to society. These systems are either based on crop or livestock production, or on combinations of the two, with characteristics that differ between regions and between levels of management intensity. In turn, they also differ in their sensitivity to projected future changes in climate, and improvements to increase climate-resilience need to be tailored to the specific needs of each system. The book will bring together a series of chapters that provide scientific insights to possible implications of projected climate changes for different important types of crop and livestock systems, and a discussion of options for adaptive and mitigative management.
