Download or read book The North American Mosaic written by Commission for Environmental Cooperation (Montréal, Québec). Secretariat and published by . This book was released on 2001 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Download or read book Lake Chilwa written by M. Kalk and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leonard C. Beadle In contrast to the more sta bie oceans, inland waters are, on the geological time scale, short-lived and are subject to great fluctuations in chemical composition and physical features. Very few lakes and rivers have existed continuously for more than a million years, and the life of the majority is to be measured in thousands or less. Earth movements, erosion and long-term climatic changes in the past have caused many of them to appear and disappear. No wonder then that most freshwater organism are especially adapted to great changes and many even to temporary extinction of their environment. Recent studies of residual sediments from existing and extinct lakes in tropical Africa have told us much about their age and the past history of their faunas and floras, from which we may deduce something about the climate and the conditions in the water in the past. The forces that have formed and moulded the African Great Lakes have been catastrophic in their violence and effects. They are not yet finished, but the present rate of change is, in human terms, too slow for direct observation of the ecological effects. The large man-made lakes are providing very good opportunities for studying the chemi cal and biological consequences of the initial filling but, once filled, they are artificially protected against major fluctuations.

Download or read book Saving Migrant Birds written by John Faaborg and published by University of Texas Press. This book was released on 2014-02-19 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Rigorous and well defended . . . Faaborg makes many fresh and, in some cases, provocative points regarding management guidelines for migrant birds.” —Kenneth Able, Great Plains Research In the 1980s, numerous scientific surveys documented both declining bird populations, especially among Neotropical songbirds that winter in the tropics, and the loss of tropical rain forest habitat. Drawing the seemingly obvious conclusion, scientists and environmental activists linked songbird declines to loss of tropical habitats and alerted the world to an impending ecological catastrophe. Their warnings led to the establishment of the Neotropical Migratory Bird Conservation Program, also known as Partners in Flight, the self-proclaimed largest conservation effort in history. Looking back over more than a decade of efforts to save migrant birds, John Faaborg offers the first serious evaluation of the state of songbird populations today, the effectiveness of conservation programs such as Partners in Flight, and the reliability and completeness of scientific research on migrant birds. Taking neither an alarmist nor a complacent approach, he shows that many factors besides habitat loss affect bird populations and that Neotropical migrants as a group are not declining dramatically, though some species adapt to habitat alteration more successfully than others. Faaborg’s state-of-the-art survey thus clarifies the kinds of information we will need and the conservation efforts we should undertake to ensure the long-term survival of Neotropical migrant birds. “Presents a carefully and closely reasoned argument about the magnitude of the conservation problems facing migrant birds, how we can reduce these problems, and how current conservation efforts have enormous value even if there is no immediate crisis.” —Scott K. Robinson, Professor and Head, Department of Animal Biology, University of Illinois

Download or read book Neotropical Migratory Birds written by Richard M. DeGraaf and published by Cornell University Press. This book was released on 1995 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thrushes, warblers, vireos, and tanagers are probably the most familiar of the Neotropical migrants--birds that breed in the United States and Canada, then journey to spend the winter in the Caribbean, Mexico, or southward. But this extraordinary group actually comprises a large number of diverse species, including waterfowl, shorebirds, terns, hawks, flycatchers, and hummingbirds. In their compendious review of information on these birds, Richard M. DeGraaf and John H. Rappole illuminate the need for a thorough understanding of the ecology of each species, one that exte4nds throughout the entire life cycle. The authors argue convincingly that conservation efforts must be based on such an understanding and carried out across a species' range--not limited to the breeding grounds. This book is the first to summarize in one volume much-needed practical data about the distribution and breeding habitat requirements of migratory birds in North and South America. The body of the book consists of natural history accounts of more than 350 species of Neotropical migrants, including a brief description of each bird's range, status, habitats on breeding grounds, nest site, and wintering areas. The authors provide a complete range map of each species' distribution in the Western Hemisphere as well as notes on the distribution--basic data that until recently have largely been unavailable in usable form to ornithologists and land and resource managers. An appendix lists species that are increasing or decreasing at significant rates in various physiographic regions of North America.

Download or read book Fiscal Federalism and Political Decentralization written by Nuria Bosch and published by Edward Elgar Publishing. This book was released on 2008-01-01 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: This highly original book analyzes political decentralization and fiscal federalism in Canada and Germany, both traditional federal countries, and in Spain, a unitarian country engaged in the last two decades in a process of decentralization. The three key issues required for a well designed financing system are analyzed in depth herein, namely: tax assignment, equalization grants (i.e. redistribution of money from the wealthy regions or the national government to poorer regions) and the role of regional government in the administration of taxes. Fiscal Federalism and Political Decentralization will be of particular interest to academics and researchers of economics, public economics, public finance and public choice. It will also appeal to politicians and policy makers as well as organizations and agencies related to the economy and fiscal federalism.
Download or read book Exile and Cultural Hegemony written by Sebastiaan Faber and published by Vanderbilt University Press. This book was released on 2002 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: After Francisco Franco's victory in the Spanish Civil War, a great many of the country's intellectuals went into exile in Mexico. During the three and a half decades of Francoist dictatorship, these exiles held that the Republic, not Francoism, represented the authentic culture of Spain. In this environment, as Sebastiaan Faber argues in Exile and Cultural Hegemony, the Spaniards' conception of their role as intellectuals changed markedly over time. The first study of its kind to place the exiles' ideological evolution in a broad historical context, Exile and Cultural Hegemony takes into account developments in both Spanish and Mexican politics from the early 1930s through the 1970s. Faber pays particular attention to the intellectuals' persistent nationalism and misplaced illusions of pan-Hispanist grandeur, which included awkward and ironic overlaps with the rhetoric employed by their enemies on the Francoist right. This embrace of nationalism, together with the intellectuals' dependence on the increasingly authoritarian Mexican regime and the international climate of the Cold War, eventually caused them to abandon the Gramscian ideal of the intellectual as political activist in favor of a more liberal, apolitical stance preferred by, among others, the Spanish philosopher Jose Ortega y Gasset. With its comprehensive approach to topics integral to Spanish culture, both students of and those with a general interest in twentieth-century Spanish literature, history, or culture will find Exile and Cultural Hegemony a fascinating and groundbreaking work.

Download or read book Defending the Land of the Jaguar written by Lane Simonian and published by University of Texas Press. This book was released on 2010-07-05 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexican conservationists have sometimes observed that it is difficult to find a country less interested in the conservation of its natural resources than is Mexico. Yet, despite a long history dedicated to the pursuit of development regardless of its environmental consequences, Mexico has an equally long, though much less developed and appreciated, tradition of environmental conservation. Lane Simonian here offers the first panoramic history of conservation in Mexico from pre-contact times to the current Mexican environmental movement. He explores the origins of conservation and environmental concerns in Mexico, the philosophies and endeavors of Mexican conservationists, and the enactment of important conservation laws and programs. This heretofore untold story, drawn from interviews with leading Mexican conservationists as well as archival research, will be important reading throughout the international community of activists, researchers, and concerned citizens interested in the intertwined issues of conservation and development.
Download or read book Narrative Threads written by Jeffrey Quilter and published by University of Texas Press. This book was released on 2010-07-05 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Inka Empire stretched over much of the length and breadth of the South American Andes, encompassed elaborately planned cities linked by a complex network of roads and messengers, and created astonishing works of architecture and artistry and a compelling mythology—all without the aid of a graphic writing system. Instead, the Inkas' records consisted of devices made of knotted and dyed strings—called khipu—on which they recorded information pertaining to the organization and history of their empire. Despite more than a century of research on these remarkable devices, the khipu remain largely undeciphered. In this benchmark book, twelve international scholars tackle the most vexed question in khipu studies: how did the Inkas record and transmit narrative records by means of knotted strings? The authors approach the problem from a variety of angles. Several essays mine Spanish colonial sources for details about the kinds of narrative encoded in the khipu. Others look at the uses to which khipu were put before and after the Conquest, as well as their current use in some contemporary Andean communities. Still others analyze the formal characteristics of khipu and seek to explain how they encode various kinds of numerical and narrative data.
