Available in PDF, EPUB and Kindle. Book excerpt: Soil degradation is one of the most topical environmental threats. A number of processes causing soil degradation, specifically erosion, compaction, salinization, pollution, and loss of both organic matter and soil biodiversity, are also strictly connected to agricultural activity and its intensification. The development and adoption of sustainable agronomic practices able to preserve and enhance the physical, chemical, and biological properties of soils and improve agroecosystem functions is a challenge for both scientists and farmers. The Special Issue entitled "Sustainable Agriculture and Soil Conservation" collects 12 original contributions addressing the state of the art of sustainable agriculture and soil conservation. The papers cover a wide range of topics, including organic agriculture, soil amendment and soil organic carbon (SOC) management, the impact of SOC on soil water repellency, the effects of soil tillage on the quantity of SOC associated with several fractions of soil particles and depth, and SOC prediction, using visible and near-infrared spectra and multivariate modeling. Moreover, the effects of some soil contaminants (e.g., crude oil, tungsten, copper, and polycyclic aromatic hydrocarbons) are discussed or reviewed in light of the recent literature. The collection of the manuscripts presented in this Special Issue provides a relevant knowledge contribution for improving our understanding on sustainable agriculture and soil conservation, thus stimulating new views on this main topic.

Available in PDF, EPUB and Kindle. Book excerpt: The recent development of ideas on biodiversity conservation was already being considered almost three-quarters of a century ago for crop plants and the wild species related to them, by the Russian geneticist N.!. Vavilov. He was undoubtedly the first scientist to understand the impor tance for humankind of conserving for utilization the genetic diversity of our ancient crop plants and their wild relatives from their centres of diversity. His collections showed various traits of adaptation to environ mental extremes and biotypes of crop diseases and pests which were unknown to most plant breeders in the first quarter of the twentieth cen tury. Later, in the 1940s-1960s scientists began to realize that the pool of genetic diversity known to Vavilov and his colleagues was beginning to disappear. Through the replacement of the old, primitive and highly diverse land races by uniform modem varieties created by plant breed ers, the crop gene pool was being eroded. The genetic diversity of wild species was equally being threatened by human activities: over-exploita tion, habitat destruction or fragmentation, competition resulting from the introduction of alien species or varieties, changes and intensification of land use, environmental pollution and possible climate change.

Download or read book The Economics of the Trade Union written by Alison L. Booth and published by Cambridge University Press. This book was released on 1995 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyses the crucial features of unionised labour markets. The models in the book refer to labour contracts between unions and management, but the method of analysis is also applicable to non-union labour markets where workers have some market power. In this book, Alison Booth, a researcher in the field, emphasises the connection between theoretical and empirical approaches to studying unionised labour markets. She also highlights the importance of taking into account institutional differences between countries and sectors when constructing models of the unionised labour market. While the focus of the book is on the US and British unionised labour markets, the models and analytical methods are applicable to other industrialised countries with appropriate modifications.

Download or read book Enterprise and American Law 1836 1937 written by Herbert Hovenkamp and published by Harvard University Press. This book was released on 2009-06-01 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this integration of law and economic ideas, Herbert Hovenkamp charts the evolution of the legal framework that regulated American business enterprise from the time of Andrew Jackson through the first New Deal. He reveals the interdependent relationship between economic theory and law that existed in these decades of headlong growth and examines how this relationship shaped both the modern business corporation and substantive due process. Classical economic theory--the cluster of ideas about free markets--became the guiding model for the structure and function of both private and public law. Hovenkamp explores the relationship of classical economic ideas to law in six broad areas related to enterprise in the nineteenth and early twentieth centuries. He traces the development of the early business corporation and maps the rise of regulated industry from the first charterbased utilities to the railroads. He argues that free market political economy provided the intellectual background for constitutional theory and helped define the limits of state and federal regulation of business behavior. The book also illustrates the unique American perspective on political economy reflected in the famous doctrine of substantive due process. Finally, Hovenkamp demonstrates the influence of economic theory on labor law and gives us a reexamination of the antitrust movement, the most explicit intersection of law and economics before the New Deal. Legal, economic, and intellectual historians and political scientists will welcome these trenchant insights on an influential period in American constitutional and corporate history.

Download or read book The Routledge Companion to Urban Regeneration written by Michael E. Leary and published by Routledge. This book was released on 2013-10-30 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, urban regeneration policy makers and practitioners have faced a number of difficult challenges, such as sustainability, budgetary constraints, demands for community involvement and rapid urbanization in the Global South. Urban regeneration remains a high profile and important field of government-led intervention, and policy and practice continue to adapt to the fresh challenges and opportunities of the 21st century, as well as confronting long standing intractable urban problems and dilemmas. This Companion provides cutting edge critical review and synthesis of recent conceptual, policy and practical developments within the field. With contributions from 70 international experts within the field, it explores the meaning of ‘urban regeneration’ in differing national contexts, asking questions and providing informed discussion and analyses to illuminate how an apparently disparate field of research, policy and practice can be rendered coherent, drawing out common themes and significant differences. The Companion is divided into six sections, exploring: globalization and neo-liberal perspectives on urban regeneration; emerging reconceptualizations of regeneration; public infrastructure and public space; housing and cosmopolitan communities; community centred regeneration; and culture-led regeneration. The concluding chapter considers the future of urban regeneration and proposes a nine-point research agenda. This Companion assembles a diversity of approaches and insights in one comprehensive volume to provide a state of the art review of the field. It is a valuable resource for both advanced undergraduate and postgraduate students in Urban Planning, Built Environment, Urban Studies and Urban Regeneration, as well as academics, practitioners and politicians.
