Book Synopsis Land Use Competition by : Jörg Niewöhner
Download or read book Land Use Competition written by Jörg Niewöhner and published by Springer. This book was released on 2016-07-29 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contributes to broadening the interdisciplinary knowledge basis for the description, analysis and assessment of land use practices. It presents conceptual advances grounded in empirical case studies on four main themes: distal drivers, competing demands on different scales, changing food regimes and land-water competition. Competition over land ownership and use is one of the key contexts in which the effects of global change on social-ecological systems unfold. As such, understanding these rapidly changing dynamics is one of the most pressing challenges of global change research in the 21st century. This book contributes to a deeper understanding of the manifold interactions between land systems, the economics of resource production, distribution and use, as well as the logics of local livelihoods and cultural contexts. It addresses a broad readership in the geosciences, land and environmental sciences, offering them an essential reference guide to land use competition.
Book Synopsis New Forms of Urban Agriculture: An Urban Ecology Perspective by : Jessica Ann Diehl
Download or read book New Forms of Urban Agriculture: An Urban Ecology Perspective written by Jessica Ann Diehl and published by Springer Nature. This book was released on 2022-02-18 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eating locally and developing an urban-rural food continuum is a rapidly evolving movement. Integration of multi-functional forms of agriculture — termed New Forms of Urban Agriculture (NFUA) — could be a critical adaptation to strengthen this movement and for the sustainability of cities. While NFUA have the potential to provide diverse benefits to humans, there is an absence of reliable empirical data on the scale and impact of urban resources on NFUA which has a profound impact on its viability and sustainability. In this book, we shift the focus from how NFUA have potential to impact the urban system to investigate the potential impacts of urban resources on NFUA. Access to resources such as land, labour, clean water, etc. are major barriers to enter the agriculture sector in the cities; the chapters in this book present projects or reviews recent research on the subject from different cities in the world. This edited volume offers critical perspectives from diverse disciplines, expertise, and geographic contexts related to the actual and potential role of urban and peri-urban agriculture in the developing and the developed world where forms, adaptations, and debates around NFUA vary distinctively. Using and urban ecology lens, the book provides empirical evidence of how urban resources of land, water/waste, labour, and biodiversity impact NFUA.
Book Synopsis A Green and Permanent Land by : Randal S. Beeman
Download or read book A Green and Permanent Land written by Randal S. Beeman and published by . This book was released on 2001 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once patronized primarily by the counterculture and the health food establishment, the organic food industry today is a multi-billion-dollar business driven by ever-growing consumer demand for safe food and greater public awareness of ecological issues. Assumed by many to be a recent phenomenon, that industry owes much to agricultural innovations that go back to the Dust Bowl era. This book explores the roots and branches of alternative agricultural ideas in twentieth-century America, showing how ecological thought has challenged and changed agricultural theory, practice, and policy from the 1930s to the present. It introduces us to the people and institutions who forged alternatives to industrialized agriculture through a deep concern for the enduring fertility of the soil, a passionate commitment to human health, and a strong advocacy of economic justice for farmers. Randal Beeman and James Pritchard show that agricultural issues were central to the rise of the environmental movement in the United States. As family farms failed during the Depression, a new kind of agriculture was championed based on the holistic approach taught by the emerging science of ecology. Ecology influenced the "permanent agriculture" movement that advocated such radical concepts as long-term land use planning, comprehensive soil conservation, and organic farming. Then in the 1970s, "sustainable agriculture" combined many of these ideas with new concerns about misguided technology and an over-consumptive culture to preach a more sensible approach to farming. In chronicling the overlooked history of alternative agriculture, A Green and Permanent Land records the significant contributions of individuals like Rex Tugwell, Hugh Bennett, Louis Bromfield, Edward Faulkner, Russell and Kate Lord, Scott and Helen Nearing, Robert Rodale, Wes Jackson, and groups like Friends of the Land and the Practical Farmers of Iowa. And by demonstrating how agriculture also remains central to the public interest—especially in the face of climatic crises, genetically altered crops, and questionable uses of pesticides—this book puts these issues in historical perspective and offers readers considerable food for thought.
Book Synopsis Environment, Development and Sustainability in India: Perspectives, Issues and Alternatives by : Manish K. Verma
Download or read book Environment, Development and Sustainability in India: Perspectives, Issues and Alternatives written by Manish K. Verma and published by Springer Nature. This book was released on 2021-03-18 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive account of asymmetric linkage in the trilogy of environment, development and sustainability and its impact on society. It examines varied perspectives and issues of development related to environmental destruction and sustainability challenges. By examining the recent trends of development and recording the dilemmas which are creating ecological imbalances, it explores some alternative ways of development to achieve sustainability. Divided into three parts, it has a broad canvass. The first section examines critically the ‘perspectives’ on ecology, practice and ethics, rural development and man–forest interaction in the metropolis. ‘Issues’ of dams, river, agricultural distress, environmental migration, eco-tourism, ecological conservation and land acquisition are assessed in part second. ‘Alternative’ means of development is explored in part third by incorporating chapters on the constructed wetland, biofuels, subsistence economy, water and traditional knowledge practice. This interdisciplinary book is of immense significance to academicians, researchers, postgraduate and graduate-level students of social sciences and environmental studies; policymakers, development practitioners and NGOs working in the area of environment and development.

Book Synopsis Rangeland Systems by : David D. Briske
Download or read book Rangeland Systems written by David D. Briske and published by Springer. This book was released on 2017-04-12 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.
Book Synopsis Handbook of Ecological Restoration by : Martin R. Perrow
Download or read book Handbook of Ecological Restoration written by Martin R. Perrow and published by Cambridge University Press. This book was released on 2002-09-05 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: The two volumes of this handbook provide a comprehensive account of the emerging and vibrant science of the ecological restoration of both habitats and species. Ecological restoration aims to achieve complete structural and functional, self-maintaining biological integrity following disturbance. In practice, any theoretical model is modified by a number of economic, social and ecological constraints. Consequently, material that might be considered as rehabilitation, enhancement, reconstruction or re-creation is also included. Restoration in Practice provides details of state-of-the-art restoration practice in a range of biomes within terrestrial and aquatic (marine, coastal and freshwater) ecosystems. Policy and legislative issues on all continents are also outlined and discussed. The accompanying volume, Principles of Restoration defines the underlying principles of restoration ecology.
