        Economics of Livestock Disease Insurance

        Concepts, Issues and International Case Studies

        by Edited by Stephen R Koontz, Dana L Hoag, Dawn D Thilmany, John W Green, Jennifer L Grannis

        In recent years the livestock sector has been hit by a number of high-profile diseases, such as BSE,Foot and Mouth Disease and Avian Influenza. These have had a devastating economic impact onlivestock producers and the broader livestock industry. One key response has been a growing interestin livestock disease insurance. However there is a need for greater understanding of private incentives,market impacts, and public policy perspectives on regional, national and international levels, if livestockinsurance products and complementary risk management programmes are to be developed.This book provides a balanced and broad-ranging overview of the economics of livestock diseaseinsurance. It covers both general issues and specific case studies drawn from the USA, Canada, Europeand Australia or focussing on specific issues. The book is unique in addressing this subject and willinterest readers in agricultural business and economics, veterinary science and the livestock sector.

        Freshwater Nematodes

        Ecology and Taxonomy

        by Edited by Eyualem-Abebe, Istvan Andrassy, Walter Traunspurger

        Nematodes are the most numerous metazoans in aquatic sediments. The majority of conducted studies on these aquatic forms focus mainly on those in marine and estuarine habitats. Nematodes from inland water bodies have been relatively forgotten or ignored. Recognizing this serious drawback and its impact on research on nematodes, this book brings together the available information on freshwater nematodes. It addresses the taxonomy of this extremely diverse phylum and provides analysis of its ecology in freshwater habitats from nematologists from 12 countries worldwide. Descriptions of each taxon at genus-level and above are provided with an augmenting pictorial guide to the currently valid genera. Also, a complete, up-to-date and valid species-list is given for every genus with an emphasis on those reported from freshwater bodies.

        Land Use Changes in Tropical Watersheds

        Evidence, Causes and Remedies

        by Edited by Ian Coxhead, Gerald E Shively

        This book studies land use change in tropical landscapes, with particular emphasis on the economic processes that influence rates of land degradation and forest clearing. Multidisciplinary contributions draw lessons from a rich, decade-long collection of economic, social and environmental data on the Manupali upland watershed in the southern Philippines. Through this detailed case study the book documents forces leading to land use changes, in particular the potential impacts of institutional evolution and policy reforms, and highlights interrelationships between biological, economic, and social phenomena.

        Irrigation and Drainage Performance Assessment

        Practical Guidelines

        by Marinus G Bos, Martin Burton, David J Molden

        Effective irrigation and drainage systems are essential if growing demands for water resources are to be met. For the use of water for irrigation to be improved we must understand current levels of performance. This book draws together the growing body of knowledge on irrigation and drainage performance assessment that has been gained over the last twenty years. It provides guidelines for practitioners to enable them to design and carry out performance assessment and implement performance-based management. Developed by a working group of the International Commission on Irrigation and Drainage (ICID) it provides a generic framework for performance assessment with guidance on the theory and practice of how to audit and assess the performance of irrigation and drainage schemes.

        Irrigation and River Basin Management

        Options for Governance and Institutions

        by Edited by Mark Svendsen

        With increasing water scarcity, pressure to re-allocate water from agriculture to other uses mounts, along with a need to put in place institutional arrangements to promote 'higher value' uses of water. Many developing countries are now experimenting with establishing new institutional arrangements for managing water at the river basin level.This book, based on research by IWMI and others, reviews basin management in six developed and developing countries. It describes and applies a functional theory of river basin management, based on the idea that there is a minimum set of functions required to manage basins effectively and a set of basic conditions that enable effective management institutions to emerge. The book examines the experiences of both developed and developing countries in order to see what lessons can be learned and to identify what constitutes the core of a 'theory of river basin management'. It concludes that although it is difficult for developing countries to adopt approaches and institutional designs directly from developed countries, basic principles and lessons are transferable.

        Organic 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.

        Water Dynamics in Plant Production

        by Wilfried Ehlers, Michael Goss

        In many regions of the world, water is scarce. This causes a problem in plant production, as plants rely on water stored in the soil to meet their needs; thus it is the principal factor limiting crop production.Water Dynamics in Plant Production describes the basic scientific principles of water transport in the soil-plant-atmosphere continuum, explains the linkage between transpirational water use and dry matter production and presents various agronomic strategies to adapt to climate water shortage.

        Soil Fertility Decline in the Tropics

        With Case Studies on Plantations

        by Alfred E Hartemink

        Wide coverage of soils and perennial cropping systems in the tropicsSynthesis of decades of researchChallenges assumptions on the benefits of plantations for soil fertilityIt is generally assumed that soil fertility decline is widespread in the tropics and that this is largely associated with annual cropping and subsistence farming. In contrast, perennial plant cover (as in plantation agriculture) provides better protection for the soil.This book reviews these concepts, focusing on soil chemical changes under different land-use systems in the tropics. These include perennial crops, annual crops and forest plantations. Two case studies, on sisal plantations in Tanzania and sugar cane in Papua New Guinea, are presented for detailed analysis. The author demonstrates that soil fertility decline is also a problem on plantations.

        Waste Composting for Urban and Peri-Urban Agriculture

        Closing the Rural-Urban Nutrient Cycle in Sub-Saharan Africa

        by Edited by Pay Drechsel, Dagmar Kunze

        Rapid urbanization has created a major challenge with regard to waste management and environmental protection. However, the problem can be ameliorated by turning organic waste into compost for use as an agricultural fertilizer in peri-urban areas. This is especially significant in less developed countries, where food security is also a key issue. This book addresses these subjects and is based on papers presented at a workshop held in Ghana by the International Board for Soil Research and Management (IBSRAM, now part of the International Water Management Institute) and FAO. Special reference is given to Sub-Saharan Africa, with acknowledgement to experiences from other parts of the world. Contributing authors are from several European, as well as African, countries.

        Vranesh's Colorado Water Law

        by James N Corbridge Jr , Teresa A Rice

        Vranesh's Colorado Water Law is the second edition of the massive three-volume treatise written by the late George Vranesh and published in 1987. Editors James N Corbridge Jr. and Teresa A Rice have reduced the original work from three volumes to one, and they have substantially rewritten and reorganised it to make it more accessible for those involved with and interested in water law and policy. Colorado water law cases decided since 1987, along with relevant federal cases, have been included; statutory material has also been updated and discussed; and recent emerging doctrines in Colorado water law are analysed in detail, with appropriate citations. Much of the historical detail in the original work has been retained, but it has been shortened to increase the book's utility as a guide to Colorado water law as it exists today.

        Dredging Coastal Ports

        An Assessment of the Issues

        by Marine Board; National Research Council

        Are the nation's ports adequate for our present and future needs? This volume points out that no significant new deep-water construction has occurred for a decade, and provides the information and analysis needed to goad the ports and the federal government into action. The book asks three questions: Is additional port construction and maintenance dredging needed now or over the next 20 years? What would prevent dredging if it is needed? What alternatives could make additional dredging possible? The book identifies several problems in dredging ports, including the long interval between a decision to deepen a port and the time the alterations are complete. The United States needs to speed port construction to meet changing needs, and the committee recommends that we prepare for future needs by dredging now.
