With all of the environmental and social problems confronting our food systems today, it is apparent that none of the strategies we have relied on in the pasthigher-yielding varieties, increased irrigation, inorganic fertilizers, pest damage reductioncan be counted on to come to the rescue. In fact, these solutions are now part of the problem. It i

Book Description
Good agroecological practices are indispensable for the development of sustainable agriculture. In this book, principles, diversity and applications of agroecological practices for a range of systems are presented, transforming scientific research and participatory knowledge of production into practical application. It illustrates a broad range of research and teaching being used within the farming community to demonstrate best practice and current state-of-play within the field. Agroecological methods used in crop farming, grass-based livestock farming, fish production, and other complex farming systems are discussed. Conclusions are drawn from studies to provide an outlook on future trends of agroecological practices and on policies supporting implementation. Due to emphasis on real-life application, it is relevant not only to students of the agricultural sciences and public policy, but also to researchers, stakeholders and policy makers involved in the development of sustainable agriculture.

Book Description
Find an interdiscliplinary view of sustainable agriculture that emphasizes the potential contributions of ecology to agricultural sustainability in this groundbreaking book. Integrating Sustainable Agriculture, Ecology, and Environmental Policy explores how ecological knowledge, applied as part of a multidisciplinary effort, can be used to design a sustainable and environmentally sound agriculture. A more ecologically based agriculture can increase production efficiency and decrease environmental impacts, but hard choices regarding population control, energy conservation, and land use must still be made. This interdisciplinary approach ensures that the results are beneficial to all components, for example, an ecologically based management scheme which bankrupts the farmer is not considered a viable option for sustainable agriculture. These thought-provoking chapters are an excellent introduction to the contributions of ecological principles to an environmentally sound sustainable agriculture. This multidisciplinary examination provides readers interested in agriculture with a valuable introduction to related work in other fields including ecology and economics. Agronomists, ecologists, educators, and policymakers will find essential information on diverse topics including: the definition and measurement of ecological sustainability in agriculture landscape ecology and the design of sustainable agricultural landscapes soil ecology as a foundation for sustainable agriculture Federal agricultural policies as incentives or deterrent to sustainable agriculture applying farming systems research and extension to sustainable agriculture population growth and other threats to sustainable agriculture environmental policies and their effects on sustainable agriculture the role of precollege education in developing sustainable agriculture

Book Description
Soil is the Earth’s living skin. It provides anchorage for roots, holds water long enough for plants to make use of it and the nutrients that sustain life – otherwise the Earth would be as barren as Mars. It is home to myriad micro-organisms and armies of microscopic animals as well as the familiar earthworm that accomplish biochemical transformations from fixing atmospheric nitrogen to recycling wastes; it receives and process all fresh water, provides the foundations for our built environment; and comprises the biggest global carbon store that we know how to manage. This book is about the best soil in the world - the black earth or chernozem: how it is being degraded by farming and how it may be farmed sustainably. Industrialisation of farming has laid bare contradictions between the unforgiving laws of ecology and economics. Soil organic matter is the fuel that powers soil systems and the cement that holds the soil together – and in place – but agriculture is burning it up faster than it is being formed: even the chernozem cannot long survive this treatment. Here is the evidence for this trend and, based on long-term field experiments, ecological principles for sustainable agriculture that can reverse the trend and, at the same time, feed the world. Unlike other volumes in the series, this is not an edited collection of scientific papers. The authors have chosen the classical monograph to be near to the reader from beginning to end - to convey their anxiety about the state of the land and their optimism about the possibility of retrieving the situation by changing the social and political approach to the land so as to provide the necessary incentives for sustainable land use and management.

Book Description
During the 4th ESA-Congress, held in the Netherlands, 7-11 July 1996, a new perspective for agronomy emerged. Various contributions demonstrate the need for a new role of agronomy and its tools. In recent decades, agriculture has evolved from an activity with mainly productivity aims, into an issue conciliating environmental, agricultural, and economic and social objectives. Placing agriculture in such a broadened perspective requires a different agronomy, with new tools and approaches at a range of aggregration levels. It calls for detailed knowledge concerning the functioning, productivity and ecological relationships of agricultural plants and crops. In addition, it calls for a constant update and synthesis of existing and newly generated knowledge, the design of new ideotypes and genotypes, new production technologies, cropping systems, farming systems and agro-ecological land use systems. This proceedings book presents a set of case studies illustrating the various agronomic tools that can be used for specific agronomic questions. The case studies are grouped in sections illustrating relevant subquestions in developing an agriculture with broadened objectives. The book starts with an introductory paper on the role of agronomy in research and education in Europe. The second section deals with agricultural land use, food security and environment. This is followed by a set of papers describing experimental research and modeling approaches used to design new ideotypes of crops, including physiological properties in relation to growth factors such as radiation, CO2, temperature and water. Sustained soil fertility directly links to nutrient cycling and soil organic matter. A selected set of papers addresses the improvements in resource use efficiency and as such their contribution towards economic, environmental and agricultural objectives. The final section addresses the design of integrated and ecological arable farming systems. It highlights the role of prototyping interaction with leading-edge farmers, as promising tools to design, implement and test new farming systems. It is hoped that the activities of the European Society for Agronomy and the Proceedings of its 4th Congress will stimulate to serve the new perspectives of agronomy, i.e. to adopt ecological principles, to optimally manage the use of resources and to meet social and economic objectives.

Book Description
Agroecology is the science of applying ecological concepts and principles to the design, development, and management of sustainable agricultural systems. The Ecology of Agroecosystems highlights a collection of alternative agricultural methodologies and philosophies and provides an interdisciplinary approach that bridges the sociopolitical and historical context of agriculture. It includes the technical issues in a serious and ecological fashion and captures the complex merging of ecology, agriculture, politics and economics in both a historical and contemporary context. Readers will learn not only about the ethical and moral elements related to producing food of questionable quality while possibly impairing the environment, but also about the soil chemistry involved.

Book Description
Focusing on the ecology of agricultural ecosystems, this volume aims to demonstrate how the fundamental principles of ecology operate in agricultural settings and how these principles can be used to increase the productivity, sustainability and environmental quality of crop production. Chapters cover agricultural topics in physiological ecology, community ecology and ecosystems ecology. They also provide examples from crop species and production systems. Other features include an ecological perspective on agricultural production and resource utilization, reviews of issues in crop ecology by researchers and examples of ecological approaches to solving problems in crop management and environmental quality.
