Reduce the environmentally negative aspects of industrial agriculture with an ecologically sound philosophy! New Dimensions in Agroecology explores the latest developments in the emerging science of agroecology, focusing on how these new concepts and cutting-edge tools will help minimize the impact of agriculture on the environment and foster the use of sustainable agricultural practices. This book expands your scope of thinking by providing information on current innovative agroecological research and education as well as emerging issues, such as biotechnology and climate change. Prominent specialists from around the world offer a diversity of stimulating perspectives and topics that will benefit agricultural researchers, extension personnel, and upper-level students in agroecology, ecology, and agronomy programs. In New Dimensions in Agroecology, you will learn why conventional agriculture practices frequently result in environmental problems such as eutrophication at the landscape scale, reduction in soil quality, and decreased biodiversity. This timely tool contributes practical suggestions to design sustainable crop and meat production systems that replace current wasteful and unsustainable industrial agriculture to nourish the world without major damage to the health and quality of our total environment. The book points to future possibilities for research and application with the hope that agroecology becomes the new discipline in agricultural issues rather than just a buzzword. New Dimensions in Agroecology covers groundbreaking investigations on a wide variety of agriculture and ecology, including: holistic landscape-level approaches the integration of ecological principles into cropping systems the utilization of biodiversity in agriculture new ways of seeing the soil in agrosystems ecological pest management and its extension and much more! New Dimensions in Agroecology goes beyond preserving the total sustainability of our agricultural systems, including social, environmental, and economic measures of sustainability in the equation. Generously enhanced with tables, figures, models, and diagrams, this book scrutinizes the current state of affairs in agriculture and presents a better solution. Change will not come easily, but this text is the first step towards a new, environmentally acceptable way.

An invaluable source of up-to-date information on all major aspects of weed persistence Weeds negatively impact crop yields, the quality of agricultural produce, the health of livestock and ecosystems, and various aspects of human life. Despite significant expenditures of time, money, and resources by agricultural producers, land managers, and the general public, weeds persist. Developing new methods for protecting crops and the environment requires a thorough understanding of the persistence mechanisms of weeds. In Persistence Strategies of Weeds, an international team of expert authors provide detailed information on weed seed biology, identify the vulnerabilities of different weeds, and address the underlying issues behind the problem of weed persistence despite various management methods including herbicides. Presenting a comprehensive approach to the subject, the authors describe what is already understood about weed persistence and what yet needs to be determined. Topics include the role of seed production, dissemination, seed banks, the physiology and genetics of seed dormancy, the influence of agronomic practices, seed longevity, vegetative propagation, allelopathy, predation, soil microbes, weed evolution, and more. This authoritative volume: Examines the genetic flexibility of weeds to adapt to changes in agricultural practices and management strategies Discusses the release of allelochemicals by certain weeds that inhibit the growth of competing plant species Explores the influence of climate change on weed persistence and how the efficacy of herbicides will be affected Emphasizes the importance of sustainable crop production and reducing dependence on synthetic herbicides Provides extensive coverage of the roles of genetic, environmental, and morphological factors in the regulation of weed seed dormancy Includes an overview of persistence strategies of weeds, detailed case studies, and numerous illustrative examples Persistence Strategies of Weeds is an ideal textbook for all upper-level undergraduate and graduate students of weed and pest biology, agroecology, or organic agriculture, and a must-have reference for weed scientists and weed management professionals.
