This book describes the environmental problems associated with agriculture, particularly the use of pesticides and chemical fertilizers and the disposal of animal waste. These have become major policy issues in many countries, with the main polluting effect being on water quality. As with other types of pollution, significant reductions in agriculture's contribution to water pollution requires the application of either enforceable regulatory approaches or changes in the economic environment, so that farmers adopt environmentally-friendly production practices.

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...

This well illustrated book provides an historical and unified overview of a century and a half of research on the development, life cycles, transmission and evolution of the nematodes found in vertebrates throughout the world. This second, expanded edition includes relevant data from some 450 new references that have appeared from 1989 to 1999. The volume includes nematode parasites of humans, domestic animals and wildlife including fish. After an introductory chapter outlining general principles, the author systematically describes the biological characteristics of the 27 superfamilies of...

This volume provides background theory and practical protocols for bioassays of bacteria, viruses, fungi, microsporidia and nematodes that can be used as biological control agents against insect pests of agricultural and medical importance. In addition, experimental design and statistics, computational modeling for bioassay analysis, and relevant legislation are described. With contributions from internationally recognized scientists from their respective fields, this book will be of particular value to researchers both experienced and inexperienced in this area.

Cultural tourism has been identified as one of the most important of the global tourism markets. Europe hosts a vast treasure house of cultural attractions and the level of competition between cities, regions and nations to attract cultural tourists is increasing. This book reviews the cultural tourism market in Europe, based on recent surveys. It analyzes the way in which cultural attractions are produced for and used by cultural tourists and pays attention to specific types of cultural attractions including museums, art galleries, monuments and heritage attractions and the management,...

This book has been developed from a workshop on Technological change in agriculture and tropical deforestation organized by the Center for International Forestry Research and held in Costa Rica in March, 1999. It explores how intensification of agriculture affects tropical deforestation using case studies from different geographical regions, using different agricultural products and technologies and in differing demographic situations and market conditions. Guidance is also given on future agricultural research and extension efforts.

This second edition of the popular advanced student textbook (previously published as Worms and Disease: A Manual of Medical Helminthology) has been thoroughly updated and revised since it was first published in 1975. It includes contributions and a chapter by Prof. Derek Wakelin, University of Nottingham, UK.

* An authoritative handbook covering all human helminth infections with particular emphasis on diagnosis, treatment, clinical manifestations, pathogenesis, epidemiology and control
* Practical guidelines are given for estimating the clinical and public...

Food safety is currently one of the most important issues confronting consumers, producers and distributors. It cannot be dealt with as just a physical problem but must be considered as a multi-dimensional one, affected by politics, economics and social influences. This book focuses on the specific example of food safety in the beef industry in the USA, Canada, the UK and Australia. It outlines the experience of a number of countries with food safety problems (such as BSE) and examines: drivers for change and institutional arrangements within the four countries, whether there is a socially...

Good nutrition is fundamental to the success and sustainability of the aquaculture industry in terms of economics, fish health, high quality product production and minimizing environmental pollution. This book provides a unique, complete coverage of current information on nutrient requirements, feed formulations and feeding practices of commercially important aquaculture species cultured around the world. Each chapter contains detailed feeding information on specific species and is written by an expert nutritionist on that species. The book is of interest to those working professionally in...

This book contains edited and revised papers from a conference on -Science and Technology for Managing Plant Genetic Diversity in the 21st Century- held in Malaysia in June 2000, organized by the International Plant Genetic Resources Institute (IPGRI). It includes keynote papers and some 40 additional ones, covering 10 themes. The major scientific challenges to developing a global vision for the next century are identified and key research objectives are also discussed.
