Biological control – utilizing a population of natural enemies to seasonally or permanently suppress pests – is not a new concept. The cottony cushion scale, which nearly destroyed the citrus industry of California, was controlled by an introduced predatory insect in the 1880s. Accelerated invasions by insects and spread of weedy non-native plants in the last century have increased the need for the use of biological control. Use of carefully chosen natural enemies has become a major tool for the protection of natural ecosystems, biodiversity and agricultural and urban environments. This book offers a multifaceted yet integrated discussion on two major applications of biological control: permanent control of invasive insects and plants at the landscape level and temporary suppression of both native and exotic pests in farms, tree plantations, and greenhouses. Written by leading international experts in the field, the text discusses control of invasive species and the role of natural enemies in pest management. This book is essential reading for courses on Invasive Species, Pest Management, and Crop Protection. It is an invaluable reference book for biocontrol professionals, restorationists, agriculturalists, and wildlife biologists.

The increase in the world population and changes in welfare have led to an enormously expanding demand for food. In the industrialized world, food surpluses rather than shortages are a problem together with adverse environmental impacts from the overuse of chemicals and excessive exploitation of agricultural land. In the developing world, food production cannot keep up with population growth and the gap between demand and supply is growing. This book explores the theme of sustainable agricultural development in the developing world, with a particular focus on crop protection. Includes chapters on the ecology of food production, on sustainable agriculture and crop protection methods, on the economics of food production and more.

Exotic pests and diseases have long been an important concern in agriculture. The problem is becoming increasingly urgent and complex because agricultural trade has been liberalized worldwide, and as a consequence, the probability of spreading a disease or a pest through national borders has become a real threat, not only for the agricultural industry but also for human health and the natural environment. This edited volume’s list of international contributors reads like a Who’s Who of international agricultural research! This book includes ten interdisciplinary case studies that focus on specific pests or diseases that represent a range of threats to U.S. agriculture, wild lands and the urban landscape, and possible government responses to these threats. Each chapter combines, in an original fashion, biological foundations and implications for the public, giving powerful insights to a series of public policy issues of national and international relevance. In many instances, economic analysis of alternative policies is included. Exotic pest control is discussed in a public good general framework, and under the international regulatory laws comprised by the Sanitary and Phytosanitary Protocol of the WTO.

The magnitude of the food-waste disposal problem cannot be understated. Utilisation of food waste is of concern to the food processing industry, consumers, environmentalists, and regulators of handling and disposal systems. Food waste is not consistent in quality, is usually high in moisture content, and is only available locally. This book focuses on the challenges of utilising both wet and/or processed food waste. The regulatory environment relating to food waste, the perspective of the end-users, and practical use as animal feed is also discussed. One of the goals of this publication, other than to give a clear explanation of the subject of food waste and its uses as animal feed, is to stimulate a need for research.

The movement of sediment and associated pollutants over the landscape and into water bodies is of increasing concern with respect to pollution control, prevention of muddy floods and environmental protection. In addition, the loss of soil on site has implications for declining agricultural productivity, loss of biodiversity and decreased amenity and landscape value. The fate of sediment and the conservation of soil are important issues for land managers and decision-makers. In developing appropriate policies and solutions, managers and researchers are making greater use of erosion models to characterise the processes of erosion and their interaction with the landscape. A study of erosion requires one to think in terms of microseconds to understand the mechanics of impact of a single raindrop on a soil surface, while landscapes form over periods of thousands of years. These processes operate on scales of millimetres for single raindrops to mega-metres for continents. Erosion modelling thus covers quite a lot of ground. This book introduces the conceptual and mathematical frameworks used to formulate models of soil erosion and uses case studies to show how models are applied to a variety of purposes at a range of spatial and temporal scales. The aim is to provide land managers and others with the tools required to select a model appropriate to the type and scale of erosion problem, to show what users can expect in terms of accuracy of model predictions and to provide an appreciation of both the advantages and limitations of models. Problems covered include those arising from agriculture, the construction industry, pollution and climatic change and range in scale from farms to small and large catchments. The book will also be useful to students and research scientists as an up-to-date review of the state-of-art of erosion modelling and, through a knowledge of how models are used in practice, in highlighting the gaps in knowledge that need to be filled in order to develop even better models.

Plant diseases worldwide are responsible for billions of dollars worth of crop losses every year. With less agrochemicals being used and less new fungicides coming on the market due to environmental concerns, more effort is now being put into the use of genetic potential of plants for pathogen resistance and the development of induced or acquired resistance as an environmentally safe means of disease control. This comprehensive book examines in depth the development and exploitation of induced resistance. Chapters review current knowledge of the agents that can elicit induced resistance, genomics, signalling cascades, mechanisms of defence to pests and pathogens and molecular tools. Further chapters consider the topical application of inducers for disease control, microbial induction of pathogen resistance, transgenic approaches, pathogen population biology, trade offs associated with induced resistance and integration of induced resistance in crop protection. The book concludes with a consideration of socio-economic drivers determining the use of induced resistance, and the future of induced resistance in crop protection.

This book, Plant Breeding, has it bases in an earlier text entitled An Introduction to Plant Breeding by Jack Brown and Peter Caligari, first published in 2008. The challenges facing today’s plant breeders have never been more overwhelming, yet the prospects to contribute significantly to global food security and farmers’ quality of life have never been more exciting and fulfilling. Despite this there has been a worrying decline in public funding for plant breeding-related research and support for international centers of germplasm development and crop improvement. In part, this has resulted in a serious reduction in the number of young people interested in devoting their professional careers to plant breeding as well as the number of universities offering plant breeding courses or conducting relevant research in plant breeding. The authors’ aim in writing this book is to provide an integrated and updated view of the current scientific progress related to diverse plant breeding disciplines, within the context of applied breeding programs. This excellent new book will encourage a new generation of students to pursue careers related to plant breeding and will assist a wider audience of agricultural students, agronomists, policy makers and those with an interest in agriculture in gaining insight about the issues affecting plant breeding and its key role in improving the quality of life of people and in securing sufficient food, at the quality required and at an affordable price. With comprehensive coverage including questions designed for students, and an accompanying website containing additional material to help in the study of the subject, Plant Breeding is an ideal text for all those studying plant and crop sciences, and a convenient reference source for professionals working in the area. All libraries within universities and research establishments where biological and agricultural sciences are studied and taught should have multiple copies of this book.

The problem of value pluralism permeates modern political philosophy. Its presence can be felt even when it is not explicitly the central topic under investigation. Political thinkers such as Max Weber, Isaiah Berlin and Stuart Hampshire derive pessimistic, sometimes tragic, conclusions from their reflections upon pluralism. On the other hand, there is a more optimistic view represented by John Rawls and J?rgen Habermas that sees value pluralism as a problem that is easier to live with. This book presents the first accessible overview for both post- and undergraduate students of the way in which this problem has been understood and responded to by modern political thinkers.

Trace elements occur naturally in soils and some are essential nutrients for plant growth as well as human and animal health. However, at elevated levels, all trace elements become potentially toxic. Anthropogenic input of trace elements into the natural environment therefore poses a range of ecological and health problems. As a result of their persistence and potential toxicity, trace elements continue to receive widespread scientific and legislative attention. Trace Elements in Soils reviews the latest research in the field, providing a comprehensive overview of the chemistry, analysis, fate and regulation of trace elements in soils, as well as remediation strategies for contaminated soil. The book is divided into four sections: • Basic principles, processes, sampling and analytical aspects: presents an overview including general soil chemistry, soil sampling, analysis, fractionation and speciation. • Long-term issues, impacts and predictive modelling: reviews major sources of metal inputs, the impact on soil ecology, trace element deficient soils and chemical speciation modelling. • Bioavailability, risk assessment and remediation: discusses bioavailability, regulatory limits and cleanup technology for contaminated soils including phytoremediation and trace element immobilization. • Characteristics and behaviour of individual elements Written as an authoritative guide for scientists working in soil science, geochemistry, environmental science and analytical chemistry, the book is also a valuable resource for professionals involved in land management, environmental planning, protection and regulation.

The first edition of Tropical Rain Forests: an Ecological and Biogeographical Comparison exploded the myth of ‘the rain forest’ as a single, uniform entity. In reality, the major tropical rain forest regions, in tropical America, Africa, Southeast Asia, Madagascar, and New Guinea, have as many differences as similarities, as a result of their isolation from each other during the evolution of their floras and faunas. This new edition reinforces this message with new examples from recent and on-going research. After an introduction to the environments and geological histories of the major rain forest regions, subsequent chapters focus on plants, primates, carnivores and plant-eaters, birds, fruit bats and gliding animals, and insects, with an emphasis on the ecological and biogeographical differences between regions.
