Agricultural crops are prominent features of an increasing number of variously perturbed ecosystems and the landscapes occupied by these ecosystems. Yet the ecology of agricultural-dominated landscapes is only now receiving the scientific attention it has long deserved. This attention has been stimulated by the realization that all agriculture must become sustainable year after year while leaving nearby ecosystems unaffected. Ecology in Agriculture focuses exclusively on the ecology of agricultural ecosystems. The book is divided into four major sections. An introduction establishes the unique ties between agricultural and ecological sciences. The second section describes the community ecology of these sorts of ecosystems, while the final section focuses on the processes that operate throughout these agricultural landscapes. Contains an ecological perspective on agricultural production and resource utilization Includes in-depth reviews of major issues in crop ecology by active researchers Covers a range of topics in agricultural ecophysiology, community ecology, and ecosystems ecology Provides examples of ecological approaches to solving problems in crop management and environmental quality

This study is facilitated by following economic entomologists' and ecologists' changing ideas about different pest control strategies, chiefly 'chemical', 'biological', and 'integrated' control. The author then follows the efforts of one specific group of entomologists, at the University of California, over three generations from their advocacy of 'biological' controls in the 1930s and 40s, through their shifting attention to the development of an 'integrated pest management' in the context of 'big biology' during the 1970s.

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.

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. Important Notice: The digital edition of this book is missing some of the images or content found in the physical edition.

This study discusses an original proposal aimed at critically analyzing the power relations that exist in contemporary agriculture. The author endeavors herein to clarify some of the strategies that industrial agribusiness, in collusion with the state and multilateral structures, sets in motion in order to functionalize the lives of millions of farmers, so that their bodies, enunciations, and sensibilities can be repurposed in accordance with the dynamics of capital accumulation. The argument is based on the idea that agro-extractivism cannot be thought of exclusively as an economic-political and technological system, but as a complex interweaving of cultural meanings, aesthetics, and affections, which, amalgamated under the abstract name of "development", act as a support for the whole system's scaffolding. The book also explores the other side of the coin, describing how, and under what conditions, social movements are responding to the calamities generated by this model. The central thesis is that many ongoing agroecological processes are providing one of the most interesting guidelines at present for visualizing transitions towards post-development, post-extractivism, and the construction of multiple worlds beyond the sphere of capital. Political ecology of agriculture joins the calls that question the cultural project of modernity and the predatory sense imposed by the globalized food empire, and invites recognition of the importance of agroecology in the context of the end of the fossil-fuel era and the likely collapse of our industry-based civilization.

"Understanding dynamic complexity is the central scientific problem of our time. We need to look at science itself as an object of study, a historically developed way of producing knowledge that creates a rich mix of insights and confusions. Our approach needs to be partisan, rejecting the notion that feeling is the enemy of reason or that a commitment to human well-being is an enemy of objectivity. Richard Levins, an ex-tropical farmer turned Harvard University ecologist, biomathematician and philosopher of science, gives us his first book since the hugely influential The Dialectical Biologist. He argues for a good, combative, perceptive scientific method that is more reflective of the complex, dynamic world in which we live and more supportive of precautionary decisions. Talking About Trees ranges widely, from personal narratives to theoretical discussions on the need for the precautionary principle in science. Levins offers a strong critique of the industrial-commercial pathway to development; in its place he promotes an alternative development pathway that emphasizes economic viability with equity, ecological and social sustainability and empowerment of the dispossessed."

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

Sustainability has a major part to play in the global challenge of continued development of regions, countries, and continents all around the World and biological nitrogen fixation has a key role in this process. This volume begins with chapters specifically addressing crops of major global importance, such as soybeans, rice, and sugar cane. It continues with a second important focus, agroforestry, and describes the use and promise of both legume trees with their rhizobial symbionts and other nitrogen-fixing trees with their actinorhizal colonization. An over-arching theme of all chapters is the interaction of the plants and trees with microbes and this theme allows other aspects of soil microbiology, such as interactions with arbuscular mycorrhizal fungi and the impact of soil-stress factors on biological nitrogen fixation, to be addressed. Furthermore, a link to basic science occurs through the inclusion of chapters describing the biogeochemically important nitrogen cycle and its key relationships among nitrogen fixation, nitrification, and denitrification. The volume then provides an up-to-date view of the production of microbial inocula, especially those for legume crops.

Ecosystem services are the resources and processes supplied by natural ecosystems which benefit humankind (for example, pollination of crops by insects, or water filtration by wetlands). They underpin life on earth, provide major inputs to many economic sectors and support our lifestyles. Agricultural and urban areas are by far the largest users of ecosystems and their services and (for the first time) this book explores the role that ecosystem services play in these managed environments. The book also explores methods of evaluating ecosystem services, and discusses how these services can be maintained and enhanced in our farmlands and cities. This book will be useful to students and researchers from a variety of fields, including applied ecology, environmental economics, agriculture and forestry, and also to local and regional planners and policy makers.

Food security and environmental conservation are two of the greatest challenges facing the world today. It is predicted that food production must increase by at least 70% before 2050 to support continued population growth, though the size of the world's agricultural area will remain essentially unchanged. This updated and thoroughly revised second edition provides in-depth coverage of the impact of environmental conditions and management on crops, resource requirements for productivity and effects on soil resources. The approach is explanatory and integrative, with a firm basis in environmental physics, soils, physiology and morphology. System concepts are explored in detail throughout the book, giving emphasis to quantitative approaches, management strategies and tactics employed by farmers, and associated environmental issues. Drawing on key examples and highlighting the role of science, technology and economic conditions in determining management strategies, this book is suitable for agriculturalists, ecologists and environmental scientists.
