Sustainable agriculture is a key concept for scientists, researchers, and agricultural engineers alike. This book focuses on the FAM- project (FAM Munich Research Network on Agroecosystems) of the 1990s as a means to assessing, forecasting, and evaluating changes in the agroecosystems that are necessary for agricultural sustainability. The management of two separate management systems: an organic and an integrated farming system are described to provide an interdisciplinary approach Changes of matter fluxes in soils, changes of trace gas fluxes from soils, precision farming in a small scale heterogen landscape, influence of management changes on flora and fauna, as well as the development of agroecosystem models, the assessment of soil variability and the changes in nutrient status are important aspects of this book. * Contains detailed results and insight of a long-time project on agricultural sustainability * Provides an interdisciplinary approach for comprehensive understanding by scientists and researchers of soil, plants, agriculture, and environment * Includes an international perspective

Key features: Reviews the development of agroecology in China, including research, practice, management, and education regarding challenges for rural and agricultural progress Presents information from sources not readily available in the West about agricultural development in China during the last several decades Provides models and indicates starting points for future research and practice Addresses how to meet future challenges of agroecosystems from the field to the table in China from scientific, technological, and management perspectives During the past 30 years, industrialization has fundamentally changed traditional rural life and agricultural practices in China. While the incomes of farmers have increased, serious issues have been raised concerning the environment, resource depletion, and food safety. In response, the Chinese government and Chinese scientists encouraged eco-agriculture, the practice of agroecology principles and philosophy, as a way to reduce the negative consequences of large-scale industrialized systems of farming. Agroecology in China: Science, Practice, and Sustainable Management represents the work of experts and leaders who have taught, researched, and expanded Chinese agroecology and eco-agriculture for more than 30 years. It reviews decades of agricultural change to provide an integrated analysis of the progress of research and development in agroecological farming practices. The book contains research on traditional and newly developed agricultural systems in China, including intercropping systems, rainfall harvest systems, and rice–duck, rice–fish, and rice–frog co-culture systems. It covers current eco-agriculture practices in the major regions of China according to climate conditions. The book closes with a discussion of the major technical approaches, necessary policy support, and possible major development stages that must occur to allow broader agroecological implementations toward the sustainability of future food systems in China. Presenting eco-agriculture systems that are somewhat unique in comparison to those of the United States, Latin America, and Europe, Agroecology in China gives insight on how Chinese agroecologists, under the political and cultural systems specific to China, have created a strong foundation for ecologically sound agroecosystem design and management that can be applied and adapted to food systems elsewhere in the world. By using selected regional examinations of agroecological efforts in China as examples, this book provides models of how to conduct research on a broad range of agroecosystems found worldwide.

Containing new findings and reports of strategies, Biodiversity and Pest Management in Agroecosystems, Second Edition will show you how pests can be managed by enhancing beneficial biodiversity using agroecological diversification methods. Biodiversity and Pest Management in Agroecosystems, Second Edition provides you with an essential overview of the role of biodiversity in agriculture and then gets specific, with new and updated information on: the agroecology of pest management plant diversity and pest outbreaks within agroecosystems diversification strategies for pest management how sustainable farming systems are designed You'll also explore: the role of plant diversity on the biology of beneficial insects insect regulation in diverse agroecosystems manipulation of plant diversity in agroecosystems ecological and socioeconomic implications The fact is, many modern agroecosystems are unstable as a consequence of constant human intervention in crop systems which ignore ecological principles. With case studies on a variety of crops and pests, Biodiversity and Pest Management in Agroecosystems, Second Edition explores entomological aspects of agriculture and analyzes the ecological basis for the maintenance of biodiversity. It will familiarize you with the theory and practice of enhancing biological pest control in agricultural systems by managing vegetational diversity via multiple cropping, cover cropping, rotations, and other spatial and temporal designs. With studies on intercropping, cover cropping, weed management, and crop-field border vegetation manipulation, this book covers the effects of these diverse systems on pest population density and the mechanisms underlying pest reduction in polycultures.

Since the advent of agriculture approximately 12,000 years ago, human activity has created a unique set of ecosystems. However, the recent development of world markets, rapid technological advances, and other changes to farming practices have led to hugely increased pressures on farm habitats and organisms. Global human populations are rising and diets are becoming ever more complicated, leading to unrelenting requirements for increased levels of food production. Natural biotopes are becoming increasingly fragmented as agricultural activities expand around them. "Agroecosystems" now occur from the tropics to subarctic environments and comprise systems as varied as annual crops, perennial grasslands, orchards, and agroforestry systems. They presently cover almost 40% of the terrestrial land surface and significantly shape landscapes at a global scale. This key addition to the OUP Biology of Habitats Series provides a novel perspective on agroecosystems, summarising our current understanding of the basic and applied aspects of these important and complex habitats, whilst focusing on environmental concerns in the context of global change. The Biology of Agroecosystemsis is for both senior undergraduate and graduate students taking courses in agroecology, farmland ecology, conservation, and agriculture as well as the many professional ecologists, conservation biologists, and land managers requiring a concise overview of agroecology.

Water protection, food production and ecosystem health are worldwide issues. Changes in the global water cycle are affecting human well-being in many places, while widespread land and ecosystem degradation, driven by poor agricultural practices, is seriously limiting food production. Understanding the links between ecosystems, water, and food production is important to the health of all three, and sustainably managing these connections is becoming increasingly necessary. This book shows how sustainable ecosystems, especially agroecosystems, are essential for water management and food production.

This book represents a first attempt to investigate the relations between Law and Agroecology. There is a need to adopt a transdisciplinary approach to multifunctional agriculture in order to integrate the agroecological paradigm in legal regulation. This does not require a super-law that hierarchically purports to incorporate and supplant the existing legal fields; rather, it calls for the creation of a trans-law that progressively works to coordinate interlegalities between different legal fields, respecting their autonomy but emphasizing their common historical roots in rus in the process. Rus, the rural phenomenon as a whole, reflects the plurality and interdependence of different complex systems based jointly on the land as a central point of reference. “Rural” is more than “agricultural”: if agriculture is understood traditionally as an activity aimed at exploiting the land for the production of material goods for use, consumption and private exchange, rurality marks the reintegration of agriculture into a broader sphere, one that is not only economic, but also social and cultural; not only material, but also ideal, relational, historical, and symbolic; and not only private, but also public. In approaching rus, the natural and social sciences first became specialized, multiplied, and compartmentalized in a plurality of first-order disciplines; later, they began a process of integration into Agroecology as a second-order, multi-perspective and shared research platform. Today, Agroecology is a transdiscipline that integrates other fields of knowledge into the concept of agroecosystems viewed as socio-ecological systems. However, the law seems to still be stuck in the first stage. Following a reductionist approach, law has deconstructed and shattered the universe of rus into countless, disjointed legal elementary particles, multiplying the planes of analysis and, in particular, keeping Agricultural Law and Environmental Law two separate fields.
