Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Agroecosystem Diversity written by Gilles Lemaire and published by Academic Press. This book was released on 2018-10-08 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: Debate about how best to ensure the preservation of agricultural biodiversity is caught in a counter-productive polemic between proponents and critics of market-based instruments and agricultural modernization. However, it is argued in this book that neither position does justice to the range of strategies that farmers use to manage agrobiodiversity and other livelihood assets as they adapt to changing social, economic, and environmental circumstances.

Download or read book Coffee Agroecology written by Ivette Perfecto and published by Routledge. This book was released on 2015-02-11 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on principles of the conservation and optimization of biodiversity and of equity and sustainability, this book focuses on the ecology of the coffee agroecosystem as a model for a sustainable agricultural ecosystem. It draws on the authors' own research conducted over the last twenty years as well as incorporating the vast literature that has been generated on coffee agroecosystems from around the world. The book uses an integrated approach that weaves together various lines of research to understand the ecology of a very diverse tropical agroforestry system. Key concepts explored include biodiversity patterns, metapopulation dynamics and ecological networks. These are all set in a socioeconomic and political framework which relates them to the realities of farmers' livelihoods. The authors provide a novel synthesis that will generate new understanding and can be applied to other examples of sustainable agriculture and food production. This synthesis also explains the ecosystem services provided by the approach, including the economic, fair trade and political aspects surrounding this all-important global commodity.
Download or read book Biodiversity and Ecosystem Function written by Ernst-Detlef Schulze and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biota of the earth is being altered at an unprecedented rate. We are witnessing wholesale exchanges of organisms among geographic areas that were once totally biologically isolated. We are seeing massive changes in landscape use that are creating even more abundant succes sional patches, reductions in population sizes, and in the worst cases, losses of species. There are many reasons for concern about these trends. One is that we unfortunately do not know in detail the conse quences of these massive alterations in terms of how the biosphere as a whole operates or even, for that matter, the functioning of localized ecosystems. We do know that the biosphere interacts strongly with the atmospheric composition, contributing to potential climate change. We also know that changes in vegetative cover greatly influence the hydrology and biochemistry ofa site or region. Our knowledge is weak in important details, however. How are the many services that ecosystems provide to humanity altered by modifications of ecosystem composition? Stated in another way, what is the role of individual species in ecosystem function? We are observing the selective as well as wholesale alteration in the composition of ecosystems. Do these alterations matter in respect to how ecosystems operate and provide services? This book represents the initial probing of this central ques tion. It will be followed by other volumes in this series examining in depth the functional role of biodiversity in various ecosystems of the world.
Download or read book Biotic Diversity in Agroecosystems written by D. Pimentel and published by Elsevier. This book was released on 2012-12-02 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Biodiversity in Agriculture written by Paul Gepts and published by Cambridge University Press. This book was released on 2012-02-23 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of plant and animal agriculture represents one of the most important milestones in human evolution. It contributed to the development of cities, alphabets, new technologies, and ultimately to civilizations, but it has also presented a threat to both human health and the environment. Bringing together research from a range of fields including anthropology, archaeology, ecology, economics, entomology, ethnobiology, genetics and geography, this book addresses key questions relating to agriculture. Why did agriculture develop and where did it originate? What are the patterns of domestication for plants and animals? How did agroecosystems originate and spread from their locations of origin? Exploring the cultural aspects of the development of agricultural ecosystems, the book also highlights how these topics can be applied to our understanding of contemporary agriculture, its long-term sustainability, the co-existence of agriculture and the environment, and the development of new crops and varieties.
Download or read book Rethinking Food and Agriculture written by Amir Kassam and published by Woodhead Publishing. This book was released on 2020-10-18 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the central role of the food and agriculture system in driving so many of the connected ecological, social and economic threats and challenges we currently face, Rethinking Food and Agriculture reviews, reassesses and reimagines the current food and agriculture system and the narrow paradigm in which it operates. Rethinking Food and Agriculture explores and uncovers some of the key historical, ethical, economic, social, cultural, political, and structural drivers and root causes of unsustainability, degradation of the agricultural environment, destruction of nature, short-comings in science and knowledge systems, inequality, hunger and food insecurity, and disharmony. It reviews efforts towards ‘sustainable development’, and reassesses whether these efforts have been implemented with adequate responsibility, acceptable societal and environmental costs and optimal engagement to secure sustainability, equity and justice. The book highlights the many ways that farmers and their communities, civil society groups, social movements, development experts, scientists and others have been raising awareness of these issues, implementing solutions and forging ‘new ways forward’, for example towards paradigms of agriculture, natural resource management and human nutrition which are more sustainable and just. Rethinking Food and Agriculture proposes ways to move beyond the current limited view of agro-ecological sustainability towards overall sustainability of the food and agriculture system based on the principle of ‘inclusive responsibility’. Inclusive responsibility encourages ecosystem sustainability based on agro-ecological and planetary limits to sustainable resource use for production and livelihoods. Inclusive responsibility also places importance on quality of life, pluralism, equity and justice for all and emphasises the health, well-being, sovereignty, dignity and rights of producers, consumers and other stakeholders, as well as of nonhuman animals and the natural world. Explores some of the key drivers and root causes of unsustainability , degradation of the agricultural environment and destruction of nature Highlights the many ways that different stakeholders have been forging 'new ways forward' towards alternative paradigms of agriculture, human nutrition and political economy, which are more sustainable and just Proposes ways to move beyong the current unsustainable exploitation of natural resources towards agroecological sustainability and overall sustainability of the food and agriculture system based on 'inclusive responsibility'

Download or read book Agrobiodiversity a training manual for farmer groups in East Africa written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-06-26 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Farmers play a crucial role in the preservation and sustainable use of agrobiodiversity. In fact, the diversity of species that support our current agricultural production systems has been carefully managed and shaped by farming communities, over the course of the history of humankind. Farmers act as custodian of the Earth’s agrobiodiversity resources, and play a big part in preserving traditional plant and animal varieties, and the knowledge associated with these. FAO has long been working on promoting approaches to agriculture that enable both the sustainable use of biodiversity resources for food and agriculture, and their conservation, and on supporting farmers to make informed decisions on their farm management and production practices. This training manual fits in this broader commitment, to support a shift towards a paradigm of agricultural production that can sustain food and nutrition security while at the same time cause the least harm to natural ecosystems. The manual is intended as an introduction to agricultural biodiversity, and to its relevance to different aspects of agricultural production and management for smallholder farmers in Kenya. It includes eight different training modules, each covering a specific aspect related to agrobiodiversity. The modules are standalone and can be used independently one from the other, depending on the user’s or project’s aim. The materials were originally prepared within the FAO- Netherlands Partnership Programme (FNPP) and have been updated, revised and published under the second phase of the European Union-funded project “Capacity-building related to multilateral environmental agreements (MEAs) in Africa, Caribbean and Pacific (ACP) countries”.
Download or read book Biodiversity in Agricultural Landscapes of Southeastern Brazil written by Carla Gheler-Costa and published by Walter de Gruyter GmbH & Co KG. This book was released on 2016-04-11 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: The state of São Paulo, Brazil, is one of the most densely populated and developed areas in South America. Such development is evident both in terms of industrialization and urbanization, as well as in agriculture, which is heavily based on sugar cane, Eucalyptus plantations and livestock. This intense land use has resulted in great alteration of the original land cover and fragmentation of natural ecosystems. For these reasons, it is almost a paradox that jaguar, a species that requires large areas of pristine forest to exist, is still found in some parts of the state of São Paulo. It is possible that wild animals could leave in coexistence with intense land use, or is it the case that such rare encounters with large wild animals in São Paulo will disappear in the near future? All ecologists are aware of the problems of habitat changes caused by humans, but it was not until recent years that researchers started to consider that the land used for production could also serve as an important habitat for many different kinds of wild species. This book is about this new approach to conservation. It also highlights the important role that sciences could and should have in this discussion in order to better understand the problems and propose possible solutions.
