Biotic Diversity in Agroecosystems


Book Description

The preservation of biodiversity is a high priority among biologists, ecologists and environmentalists. The impact that human activities have on biodiversity is clear; however, few studies have focused on the importance of biodiversity to natural and agricultural ecosystems. In fact, many natural species are essential to sustainable agricultural programs. A new school of thought is appreciating the ecological principles and benefits that diversity of natural biota have for humans and the environment. Landscape ecology and agroecology can play a major role in protecting the environment and conserving biological diversity. The practical opportunities for improving the sustainability of agriculture and making it more environmentally sound were discussed at the Symposium on Agroecology and Conservation Issues, from which 22 papers were collected for this volume. Strategies for increasing biodiversity in agricultural landscapes are provided alongside discussion that agriculture will continue to spread into forests, to meet the growing need for food. Although humans recognize the value of crop and livestock species, few really appreciate the fact that agriculture and forestry cannot function in a productive sustainable way when significant numbers of species in natural biota are lost.




Biodiversity in Agroecosystems


Book Description

between the diversity of plant and animal species and host/dependent agricultural systems. Biodiversity in Agroecosystems shows how biodiversity can be thought of not only as the rich make-up of a great number of related and competing species within an ecologically defined community, but also as the robust behavior and resilience of those species over time and as the endurance of their eco-community. This book brings to the fore new research on biodiversity in agricultural ecosystems at both micro and macro levels, heretofore available only in journals and proceedings papers.




Functional Diversity of Mycorrhiza and Sustainable Agriculture


Book Description

Functional Diversity of Mycorrhiza and Sustainable Agriculture is the first book to present the core concepts of working with Arbuscular mycorrhizal fungi to improve agricultural crop productivity. Highlighting the use of indigenous AM fungi for agriculture, the book includes details on how to maintain and promote AM fungal diversity to improve sustainability and cost-effectiveness. As the need to improve production while restricting scarce inputs and preventing environmental impacts increases, the use of AMF offers an important option for exploiting the soil microbial population. It can enhance nutrient cycling and minimize the impacts of biotic and abiotic stresses, such as soil-borne disease, drought, and metal toxicity. The book offers land managers, policymakers, soil scientists, and agronomists a novel approach to utilizing soil microbiology in improving agricultural practices. - Provides a new approach to exploiting the benefits of mycorrhizas for sustainable arable agricultural production using indigenous AMF populations and adopting appropriate crop production techniques - Bridges the gap between soil microbiology, including increasing knowledge of mycorrhiza and agronomy - Presents real-world practical insights and application-based results, including a chapter focused primarily on case studies - Includes extensive illustrative diagrams and photographs




Biodiversity Conservation and Utilization in a Diverse World


Book Description

This book "Biodiversity Conservation and Utilization in a Diverse World" sees biodiversity as management and utilization of resources in satisfying human needs in multi-sectional areas including agriculture, forestry, fisheries, wildlife and other exhaustible and inexhaustible resources. Its value is to fulfill actual human preferences and variability of life is measured by amount of genetic variation available. In viewing diversity as an ultimate moral value, one is faced with a situation in environmental preservation in order to allow components of total diversity to flourish and constitute a threat to continuous existence and decrease total diversity. The overall importance described economic benefits from bio-diversity, though difficult to measure and varying, but are limited on a local scale, increase on a regional or national scale and become potentially substantial on a transnational or global scale.




Invertebrate Biodiversity as Bioindicators of Sustainable Landscapes


Book Description

Reducing environmental hazard and human impact on different ecosystems, with special emphasis on rural landscapes is the main topic of different environmental policies designed in developed countries and needed in most developing countries. This book covers the bioindication approach of rural landscapes and man managed ecosystems including both urbanised and industrialised ones. The main techniques and taxa used for bioindication are considered in detail. Remediation and contamination is faced with diversity, abundance and dominance of biota, mostly invertebrates. Invertebrate Biodiversity as Bioindicators of Sustainable Landscapes provides a basic tool for students and scientists involved in landscape ecology and planning, environmental sciences, landscape remediation and pollution.




Conserving Biodiversity


Book Description

The loss of the earth's biological diversity is widely recognized as a critical environmental problem. That loss is most severe in developing countries, where the conditions of human existence are most difficult. Conserving Biodiversity presents an agenda for research that can provide information to formulate policy and design conservation programs in the Third World. The book includes discussions of research needs in the biological sciences as well as economics and anthropology, areas of critical importance to conservation and sustainable development. Although specifically directed toward development agencies, non-governmental organizations, and decisionmakers in developing nations, this volume should be of interest to all who are involved in the conservation of biological diversity.




Biodiversity and Pest Management in Agroecosystems


Book Description

Explore the latest research on biological control! Completely updated for 2004, this new edition examines methods for making agricultural systems less susceptible to insect pests. 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.

Structure and Function in Agroecosystem Design and Management


Book Description

Structure and Function in Agroecosystem Design and Management presents an advanced discussion of the need to design agricultural systems that 1) increase reliance on biological interactions in agroecosystems as a means of decreasing dependence on the use of large quantities of agrochemicals and the consumption of fossil fuel energy and 2) continue




Organic Farming


Book Description

Organic farming is a progressive method of farming and food production it does not mean going back to traditional (old) methods of farming. Many of the traditional farming methods used in the past are still useful today. Organic farming takes the best of these and combines them with modern scientific knowledge. Authors' task was to write a book where many different existing studies could be presented in a single volume, making it easy for the reader to compare methods, results and conclusions. As a result, studies from different countries have been compiled into one book. I believe that the opportunity to compare results and conclusions from different authors will create a new perspective in organic farming and food production. I hope that our book will help researchers and students from all over the world to attain new and interesting results in the field of organic farming and food production.
