Download or read book Productivity Effects of Cropland Erosion in the United States written by Pierre R. Crosson and published by Routledge. This book was released on 2016-03-17 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1970’s, agriculture in the United States seemed to be booming. With an extra demand for crops, extra acres were taken on to increase production which was predicted to increase further with an ever-growing population. However, concerns were beginning to be raised over the adequacy of land for crops as potential croplands began to be converted into urban areas as well as the effects of soil erosion decreasing the quality of these croplands. Originally published in 1983, this study investigates the threats to crop productivity in the U.S. with a focus on human-made problems. This title will be of interest to students of environmental studies.

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.
Download or read book Principles of Soil Conservation and Management written by Humberto Blanco-Canqui and published by Springer Science & Business Media. This book was released on 2008-09-16 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Principles of Soil Management and Conservation” comprehensively reviews the state-of-knowledge on soil erosion and management. It discusses in detail soil conservation topics in relation to soil productivity, environment quality, and agronomic production. It addresses the implications of soil erosion with emphasis on global hotspots and synthesizes available from developed and developing countries. It also critically reviews information on no-till management, organic farming, crop residue management for industrial uses, conservation buffers (e.g., grass buffers, agroforestry systems), and the problem of hypoxia in the Gulf of Mexico and in other regions. This book uniquely addresses the global issues including carbon sequestration, net emissions of CO2, and erosion as a sink or source of C under different scenarios of soil management. It also deliberates the implications of the projected global warming on soil erosion and vice versa. The concern about global food security in relation to soil erosion and strategies for confronting the remaining problems in soil management and conservation are specifically addressed. This volume is suitable for both undergraduate and graduate students interested in understanding the principles of soil conservation and management. The book is also useful for practitioners, extension agents, soil conservationists, and policymakers as an important reference material.
Download or read book Soil Quality and Soil Erosion written by Raj Ratta and published by Routledge. This book was released on 2018-12-18 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work examines the issue of accelerated soil erosion, which has become an increasingly serious concern in the twentieth century. Aspects considered include on-site impact of erosion; application of soil science to problems of non-agricultural uses of soil, such as mineland restoration, urban uses and disposal of urban wastes; soil contamination and pollution by industrial activities; and athletic and recreational uses of soil. Soil Quality and Soil Erosion will be a useful text for soil scientists, agronomists, foresters, and environmental scientists as we enter the next century.
Download or read book Soil Erosion Research Methods written by Soil and Water Conservation Society (U. S.) and published by Routledge. This book was released on 2017-10-19 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new edition of Soil Erosion Research Methods retains the themes and layout of the first edition. However, most chapters have been revised and some additional chapters have been added. There are new chapters on modeling wind and water erosion. Extensive revisions and updating have been done in chapters dealing with assessment of erosivity and erodibility, erosion, crop productivity, measuring sediment yield from river basins and field plot techniques. There is extensive updating of current statistics on the global magnitude of soil erosion by water and wind and on denudation rates. Several new authors have made significant improvements in revising and updating available information.
Download or read book Economic Policy and Sustainable Land Use written by Nico Heerink and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1980s many developing countries have implemented macro-economic policy reforms to curb inflation, reduce fiscal deficits and control foreign debt. The policy instruments used, such as exchange rate adjustment, budget cuts, trade policy reforms, public expenditure reviews and privatisation, have different and sometimes opposite consequences for agricultural land use. During the same period awareness was growing that deteriorating soil quality could become a limiting factor to increase or even sustain agricultural production. As a result, food availability and even accessibility for large population groups in developing countries may be jeopardised in the near future. Recently, quantitative models have made useful contributions to understanding the impact of economic policy reforms on the sustainability of land use. They provide a consistent analytical framework to deal with complex issues such as the direct and indirect effects of economic, agricultural, environmental and population policies, the role of market imperfections in transmitting economic policy signals, and the interactions between soil quality, agricultural production and household economic decision making. Different types of models can be distinguished: bio economic models, focussing on the link between farm household decisions and the agricultural resource base, household and village models, examining the impact of the socio-economic environment on farm household decisions, and more aggregate models, analysing interactions between sectors and their implications for sustainable land use.

Download or read book Soil Erosion Issues in Agriculture written by Danilo Godone and published by BoD – Books on Demand. This book was released on 2011-10-21 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with several aspects of soil erosion, focusing on its connection with the agricultural world. Chapters’ topics are various, ranging from irrigation practices to soil nutrient, land use changes or tillage methodologies. The book is subdivided into fourteen chapters, sorted in four sections, grouping different facets of the topic: introductive case studies, erosion management in vineyards, soil erosion issue in dry environments, and erosion control practices. Certainly, due to the extent of the subject, the book is not a comprehensive collection of soil erosion studies, but it aims to supply a sound set of scientific works, concerning the topic. It analyzes different facets of the issue, with various methodologies, and offers a wide series of case studies, solutions, practices, or suggestions to properly face soil erosion and, moreover, may provide new ideas and starting points for future researches.
