Agro-Ecosystem Diversity: Impact on Food Security and Environmental Quality presents cutting-edge exploration of developing novel farming systems and introduces landscape ecology to agronomy. It encompasses the broad range of links between agricultural development and ecological impact and how to limit the potential negative results. Presented in seven sections, each focusing on a specific challenge to sustaining diversity, the book provides insights toward the argument that by re-introducing diversity, it should be possible to maintain a high level of productivity of agro-ecosystems while also maintaining and/or restoring a satisfactory level of environment quality and biodiversity. Demonstrates that diversified agro-ecosystems can be intensified with environmental quality preserved, restored and enhanced Includes analysis of economic constraints leading to specialization of farms and regions and the social locking forces resisting to diversification of agro-ecosystems Presents a global vision of world agriculture and the tradeoff between a necessary increase in food production and restoring environment quality

Ecosystems are the basis of life and all human activities. Agroecology as an approach to foster the transition to food systems that conserve resources and improve human well-being, has been increasingly promoted by scientists, Non-Governmental Organization (NGOs), international organizations, and peasant movements. Conservation of biological diversity is very important for the proper functioning of the ecosystem and for delivering ecosystem services. Maintaining high biodiversity in agroecosystems makes agricultural production more sustainable and economically viable. During the last decades, worldwide losses of biodiversity have occurred at an unprecedented scale and agricultural intensification has been a major driver of this global change. Comprised into 14 chapters, this book integrates state of the art trends and challenges on biodiversity in agricultural ecosystems at both local and global perspective. This book opens with a chapter on plant diversity in agroecosystems and agricultural landscapes. Agricultural landscapes represent a cultural landscape group. Their origin, structure and ecological relations differ from natural landscapes considerably. Agroecology is increasingly promoted by scientists, non-governmental organizations (NGO's), international organizations and peasant movements as an approach to foster the transition to sustainable and equitable food systems. Further, this book takes a look on the governance of ecosystem services in agroecology; the ecology of plant chemistry and multi-species interactions in diversified agroecosystems; activity and variety of soil microorganisms depending on the diversity of the soil tillage system; soil fungal resources in annual cropping systems and their potential for management; nocturnal risks-high bat activity in the agricultural landscape indicates potential pesticide exposure. In this chapter, we have discussed the major effects of crop protection on biodiversity in detail regarding the persistence of biodiversity that needs to be mediated, considering the preserving of ecological properties and sustainable maintenance of biological integrity in agroecosystems. Farming systems, with their concerns of biodiversity, ecosystem services, and productivity and production issues towards progress in human needs, wellbeing, and sustainable development, are challenging in most biosphere reserves. In this book, a case study presented in last chapter assesses the levels and trends of the agro-biodiversity and ecosystem services of different farming systems in the Yayo Biosphere Reserve in Ethiopia.

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.

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.

The symposium and the resulting book on "Exploring the Role of Diversity in Sustainable Agriculture" is one of the first efforts in attempting to summarize existing knowledge on the subject. The terms diversity and biodiversity have recently come into wide public use. Most typically, they are used in discussions about conservation issues, particularly the magnitude and importance of species loss. At other times, however, diversity and biodiversity are referred to a desirable property of natural systems and, perhaps in a different sense, of human society. It is this second use of the term that has inspired this publication

Published in three other languages and growing, Managing Biodiversity in Agricultural Ecosystems takes a look at how farmers manage, maintain, and benefit from biodiversity in agricultural production systems. The volume includes the most recent research and developments in the maintenance of local diversity at the genetic, species, and ecosystem levels. Chapters cover the assessment and farmer management practices for crop, livestock, aquatic, and associated diversity (such as pollinators and soil microorganisms) in agricultural ecosystems; examine the potential role of diversity in minimizing pest and disease pressures; and present studies that exemplify the potential nutritional, ecosystem service, and financial values of this diversity under changing economic and environmental conditions. The volume contains perspectives that combine the thinking of social and biological scientists. Inappropriate or excessive use of inputs can cause damage to biodiversity within agricultural ecosystems and compromise future productivity. This book features numerous case studies that show how farmers have used alternative approaches to manage biodiversity to enhance the stability, resilience, and productivity of their farms, pointing the way toward improved biodiversity on a global scale. As custodians of the world's agricultural biodiversity, farmers are fully invested in ways to create, sustain, and assist in the evolution and adaptation of a variety of plant and animal species. Thus this text is mandatory reading for conservationists, environmentalists, botanists, zoologists, geneticists, and anyone interested in the health of our ecosystem.

While modern science has always recognized the central role that biodiversity plays in the ecological processes that maintain the Earth's equilibrium, our increasing knowledge of nature has deepened our appreciation of this principle. Consequently, those involved with implementing and maintaining sustainable agriculture systems have begun to take a far more sophisticated approach to understanding and making use of the components and mechanics of biodiversity. Providing a comprehensive and highly practical exploration of the subject, Biodiversity in Agricultural Production Systems examines abiotic ecosystem diversity and biological complexity at every relevant level. Leading researchers detail subspecies diversity, covering ecotypes, lifecycles, genes, physiology, and behavior. They also discuss species richness and supraspecies diversity, which includes foodweb interactions and non-trophic relationships, as well as above- and belowground relationships. Exploring various facets of agricultural crops and cultivation practices, this inter-disciplinary volume- Gives an overview of the pore space dynamic in agroecosystems where most soil microorganisms reside, including bacteria, fungi, protozoa, nematodes, and Tardigrada Examines the highly diverse and prominent role played by earthworms Looks at the metabolic processes occurring in soils that result in the release of greenhouse gases Outlines principles and strategies of order between interacting molecules, cells, species and communities Looks at mechanisms of competition, exploring growth regulation, transformation, and feeding strategies, as well as toxin production, mutation, and biofilm formation Discusses matter recycling and the diversity of microbial metabolism in soils Shows how long-term observation plots are used to assess soil quality Biodiversity in Agricultural Production Systems provides important information for those involved with researching and implementing sustainable agricultural systems, as well as those addressing specific challenges related to soil degradation, water management, and climatic impacts. It also provides recent research and fresh perspectives to enhance the approaches of those working in horticulture, biology, and the environmental sciences.

Genetic diversity is essential to the security of agriculture. Without the availability of a wide range of plant varieties and the genetic resources they contain, crops cannot adapt to combat the ever-changing threats of pests, diseases and climatic change. Yet, with the increasing industrialisation of modern agriculture, farming has become a business which centres on a handful of new, genetically similar 'super seeds'. Plants must evolve in order to survive, but modern agriculture has replaced diversity with uniformity, and security with vulnerability. Saving the Seed traces the decline of crop varieties in European farming and describes what is being done to safeguard genetic resources for the future. Conservation efforts by government and industry suffer from serious drawbacks, with wrangles over ownership and control of resources. The crucial work is being done by individuals and grassroots organisations, who largely go unrecognised and under-resourced. What is urgently needed are sound policies to promote the diversification of agriculture and an integrated strategy for safeguarding the genetic base of our food system. Saving the Seed contains the most up-to-date information available on genetic resources in Europe and on those working to save them. Renee Vellve is a researcher at GRAIN, a no-governmental organisation working to promote the sustainable conservation and use of genetic diversity, based on grassroots approaches to genetic resources management.
