Download or read book Soil erosion the greatest challenge for sustainable soil management written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-05-16 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite almost a century of research and extension efforts, soil erosion by water, wind and tillage continues to be the greatest threat to soil health and soil ecosystem services in many regions of the world. Our understanding of the physical processes of erosion and the controls on those processes has been firmly established. Nevertheless, some elements remain controversial. It is often these controversial questions that hamper efforts to implement sound erosion control measures in many areas of the world. This book, released in the framework of the Global Symposium on Soil Erosion (15-17 May 2019) reviews the state-of-the-art information related to all topics related to soil erosion.

Available in PDF, EPUB and Kindle. Book excerpt: Provides a unique and comprehensive assessment of soil erosion throughout Europe, an important aspect to control and manage if landscapes are to be sustained for the future. Written in two parts, Soil Erosion in Europe primarily focuses on current issues, area specific soil erosion rates, on and off-site impacts, government responses, soil conservation measures, and soil erosion risk maps. The first part overviews the erosion processes and the problems encountered within each European country, whilst the second section takes a cross-cutting theme approach. Based on an EU-funded project that has been running for four years with erosion scientists from 19 countries Reviews contemporary erosion processes and rates on arable and rangeland in Europe Looks at current issues, such as socio-economic drivers, controlling factors specific to the country and changes in land use

Download or read book Natural Resources Management in Agriculture written by Bekele Shiferaw and published by CABI. This book was released on 2005 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to increasing concerns about the degradation of natural resources and the sustainability of agriculture, many research programmes have been established in natural resource management (NRM). However, although methods for evaluating the impacts of crop improvement technologies are well developed, there is a dearth of methods for evaluating the impacts of NRM interventions. This is partly due to the complexity of interactions among natural resources, spatial and temporal dimensions of impact, and the valuation of direct and indirect environmental costs and benefits. This book discusses the unique features and methodological difficulties of NRM impact assessment. It examines the strengths and weaknesses of various impact assessment approaches, including econometric, bio-economic, and more direct methods. It also assesses and identifies data requirements for developing impact indicators and recommends suitable methodologies for assessing the impacts of NRM technologies on issues such as soil and water conservation and watershed and biodiversity management.
Download or read book Blue Revolution written by Ian R. Calder and published by Taylor & Francis. This book was released on 2012-05-16 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Blue Revolution upturns some environmental applecarts - not for the hell of it, but so we can manage our environment better.' Fred Pearce, New Scientist This updated and revised edition of The Blue Revolution provides further evidence of the need to integrate land management decision-making into the process of integrated water resources management. It presents the key issues involved in finding the balance between the competing demands for land and water: for food and other forms of economic production, for sustaining livelihoods, and for conservation, amenity, recreation and the requirements of the environment. It also advocates the means and methodologies for addressing them. A new chapter, 'Policies, Power and Perversity,' describes the perverse outcomes that can result from present, often myth-based, land and water policies which do not consider these land and water interactions. New research and case studies involving ILWRM concepts are presented for the Panama Canal catchments and in relation to afforestation proposals for the UK Midlands.

It offers a coherent view of the situation concerning land degradation and the human response to the problem. It is generally recognized that technological solutions alone cannot solve the problems of land degradation. This book discusses the role of land use and land management policies, programmes, insitutional innovations, and economic incentives for the control and prevention of land degradation. Special attention is given to legal issues at the international level and in individual countries.

Available in PDF, EPUB and Kindle. Book excerpt: Challenges scholars, policymakers, and resource managers to reexamine long-held assumptions about "environmental degradation." Through a case study of northern Thailand the authors ask how, why, and with whose influence environmental situations are defined. Their conclusion that misleading and simplistic explanations fail to address the real causes of environmental problems, and unnecessarily restrict the livelihoods of local people, will be a valuable contribution to broader international academic and policy discussions. Tim Forsyth is a reader at the London School of Economics and Political Science. Andrew Walker is a research fellow in the Research School of Pacific and Asian Studies, the Australian National University.

Download or read book Environmental Science for Environmental Management written by Timothy O'Riordan and published by Routledge. This book was released on 2014-10-13 with total page 875 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Science for Environmental Management has quickly established itself as the leading introduction to environmental science, demonstrating how a more environmental science can create an effective approach to environmental management on different spatial scales. Since publication of the first edition, environmentalism has become an increasing concern on the global political agenda. Following the Rio Conference and meetings on population, social justice, women, urban settlement and oceans, civil society has increasingly promoted the cause of a more radical agenda, ranging from rights to know, fair trade, social empowerment, social justice and civil rights for the oppressed, as well as novel forms of accounting and auditing. This new edition is set in the context of a changing environmentalism and a challenged science. It builds on the popularity and applicability of the first edition and has been fully revised and updated by the existing writing team from the internationally renowned School of Environmental Science at the University of East Anglia. Environmental Science for Environmental Management is an essential text for for undergraduate students of environmental science, environmental management, planning and geography. It is invaluable supplementary reading for environmental biology and environmental chemistry courses, as well as for engineering, economics and business studies.
