This book was released on 2018-09-03 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.

Download or read book Transport in Plants I written by M.H. Zimmermann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: When WILHELM RUHLAND developed his plan for an Encyclopedia of Plant Physiol ogy more than three decades ago, biology could still be conveniently subdivided into classical areas. Even within plant physiology, subdivisions were not too difficult to make, and general principles could be covered sufficiently in the two introductory volumes of the Encyclopedia on the physical and chemical basis of cell biology. But the situation changed rapidly even during the 12-year publication period of the Encyclopedia (1955-1967). The new molecular direction of genetics and structural research on biopolymers had an integrating effect on all other biological fields, including plant physiology, and it became increasingly difficult to keep previously distinct areas separated. RUHLAND'S overall plan included 18 volumes and about 22,000 pages. It covered the entire field of plant physiology, in most cases from the very beginning. But, as each volume appeared, it was clear that its content would soon be outdated.

Download or read book Times Gone By written by Vicente Pérez Rosales and published by Oxford University Press. This book was released on 2003-05-01 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: These memoirs trace the wild and adventurous life of Pérez Rosales from his childhood up to the 1860s. During that approximately half-century he saw and did more than a dozen ordinary men. At age eleven in Argentina he witnessed the executions of Luis and Juan Jose Carrera. From there, his activities and adventures took him on several journeys on sailing vessels around Cape Horn; to Paris, where he witnessed the July revolution of 1830; to various commercial endeavors including a distillery, the practice of medicine, and cattle smuggling; into service as an advisor to an Argentine warlord; as a miner for precious metals in the north of Chile; as participant in the California Gold Rush in 1849; as director of the government's project for German immigration and settlement in the wild south of Chile; and also as Chilean consul and immigration agent in Hamburg. Around the world, Rosales lived through many of his era's watershed moments. His exciting memoirs offer a chance to relive the rush and chaos of these times--from a much safer vantage.

Download or read book Tropical Forests and the Human Spirit written by Roger D. Stone and published by Univ of California Press. This book was released on 2001 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book is a remarkably personal report of the authors’ trans-tropical experiences with forest dwellers. The experience was extensive, sometimes spanning years, and the report is the work of professional reporters, experienced at reaching to the core of critical issues of life and survival. The story is not a pretty one, and the prognosis is not good. But in their eyes the key lies in restoring and defending the rights of forest dwellers and encouraging in every way their age-old interest in preserving the integrity of forest lands. The authors are familiar with the international agencies and their programs, their successes and failures. Roger Stone was intimately involved in the World Commission on Forests and Sustainable Development and draws heavily on that experience. The book will strengthen the conclusions of that Commission to the effect that the world’s future lies heavily entangled with the continuity of forests globally, and that continuity hinges on respect for local interests."—George M. Woodwell, Director, Woods Hole Research Center "For twenty years, we have watched TV specials on the destruction of tropical forests -- an acre a second lost, every second for twenty years. This beautifully written book takes you right to the middle of the current international debate about what to do about it. It pulls no punches and proposes its own provocative solution. It offers a perspective that cannot be ignored and an answer that needs to be tried."—James Gustave Speth, Yale School of Forestry and Environmental Science "For more than a century, the conservation movement has dedicated its energy to protecting the Earth’s biodiversity. WWF has built its conservation philosophy and foundation for over forty years on principles of sound science, effective public policy, and recognition of the fundamental role local people bring to achieving tangible conservation results on the ground. Roger Stone and Claudia D’Andrea take us on a tour of the tropical forested regions of the world and capture important lessons about the merits of local control over forest resources. Their wide-ranging portrayal of community-based forest management arrangements, set within the global context of deforestation and loss of biodiversity, provides compelling testimony to the wisdom of empowering local people and nurturing their spirit as effective forest stewards."—Kathryn S. Fuller, President, World Wildlife Fund

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 Free Spaces written by Sara Margaret Evans and published by HarperCollins Publishers. This book was released on 1986 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: What are the environments, the public spaces, in which ordinary people become participants in the complex, ambiguous, engaging conversation about democracy: participators in governance rather than spectators or complainers, victims or accomplices? What are the roots, not simply of movements against oppression, but also of those democratic social movements which both enlarge the opportunities for participation and enhance people's ability to participate in the public world? In Free Spaces, Sara M. Evans and Harry C. Boyte argue for a new understanding of the foundations for democratic politics by analyzing the settings in which people learn to participate in democracy. In their new Introduction, the authors link the concept of free spaces to recent theoretical discussions about community, public life, civil society, and social movements.
