The increased use of chemical fertilizers and pesticides in crop production has adversely affected both the environment and the agricultural economy. Not only has it led to environmental pollution, but also the increasing costs of chemical inputs and the low prices received for agricultural products have contributed to economic unprofitability and instability.The International Symposium on Agricultural Ecology and Environment was organised in order to discuss ways of achieving the goals of economically and environmentally sustainable agriculture. It is apparent that a truly multidisciplinary effort is required and for this reason the meeting was attended by authors from many different disciplines and geographical locations. Although their papers reflect a wide diversity of agroecosystem types and examples, several common themes emerge: the increased importance of biotic control of ecosystem processes in lower input systems; the key role of soil organic matter in stabilizing nutrient cycling; the importance of agricultural landscape diversity and complexity; the importance of studying ecological processes in natural and agricultural ecosystems; the critical need to integrate socio-economic and ecological approaches.

Rooted firmly in the principles of econology, the agricultural enterprise, even though having been exposed to the impact of environmental problems arising from land degradation, soil erosion, groundwater depletion and pollution and loss of biological diversity, has so far stood firm and survived to meet the food requirements of the growing population, so much so that there have been some striking instances of food glut in several countires, including some that used to sufer famiens only half a century ago.

This book analyses the nature of the relationships between crops, livestock and the bio-physical environment, and the extent to which man has managed and modified the products and environment to suit his/her own particular needs.

Presents powerful arguments against "Environmental Racism", "Incrementalism" and the "Impotence of Planning." Explores case studies of urban planning, county policies, residential development and more. Submits the authors recommendations for preserving the delicate balance of Floridas ecosystem.

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

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.
