This book was released on 1975 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annual precipitation average about 2400mm in the Amazonas Basin of which 44 percent runs off according to hydrological estimates by oltman and others. We evaluated adecedtion from aerological charts by Newell et al., assuming that tropospheric import of precipitable water must compensate river runoff. According to aerology the hidrological estimates appears too low by 15 20 percent. Independently, we tested evapotranspitation estimates from surface-energy budget calculations by Henning, who had employed the methods by budyko, Albercht and Penman, to 40 climate stations in the basin. These data also suggest that oltman underestimated runoff, i.e., overestimated evapotranspiration. In a new approach, we divided the region into six longitudinal sections of 55 kmwich and derived water and energy balances (for soil moisture and precipitable water) with models of evapo and thermoclimatonomy. The results confirm that oltaman's hydrological estimate was too low,by about 20 percent in the central section and nearyly 90 percent in the atlantic section. Climatonomical parameters lend themeslves to speculations on possible effects of large-scale deforestation tebtative calculations suggest that the primary effects in one of lowering of moisture levels and enhancing the contrast betweebdry and wet seasons.

Book Synopsis Tropical Forests and Climate by : N. Myers
Download or read book Tropical Forests and Climate written by N. Myers and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical forests affect climate, and the removal of the forests will change climate. Or not? This book discusses basic questions on how far, if at all, tropical deforestation leads to climatic change. The question of this uncertainty is particularly addressed. One important consequence of the uncertainties of whether deforestation affects climate is how scientific findings best illuminate the policy-making process.

Book Synopsis Public Policies and the Misuse of Forest Resources by : World Resources Institute
Download or read book Public Policies and the Misuse of Forest Resources written by World Resources Institute and published by Cambridge University Press. This book was released on 1988-09-30 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Six contributors explore the role of governments in accelerating the rate of forest destruction by providing direct and indirect subsidies to support what would otherwise be non-commercial logging operations. Without these financial incentives, most timber operations in the tropics would cease. In a series of country-by-country investigations, including examples from the developed and developing worlds, this book documents the government policies that are leading to the misuse of forest resources. Each is written by an authority on the county, and each contains descriptive, analytical and empirical material on key policies and their effects. The final country analysis focuses on the United States, where the consequences of the subsidized timber sales by the US Forest Service from most of the national forests are discussed. The book concludes with an overview of the impact of forest policies and the role of bilateral and multilateral agencies in their formulation. By directing attention toward the political dimension involved in forest clearance, this book will provide a clearer insight into the basic reasons why forests continue to be destroyed despite the outcry raised by conservationists.
Book Synopsis The Forest Frontier by : Peter A. Furley
Download or read book The Forest Frontier written by Peter A. Furley and published by Taylor & Francis. This book was released on 2024-06-25 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1994, this book analysed land developments, deforestation and pasture substitution, colonisation schemes and spontaneous settlement during the latter part of the 20th Century. In so doing, The Forest Frontier presents an overview of the intrinsic environmental and socio-economic resources of the Roraima, the most northerly of the Brazilian Amazon states. Roraima is of special environmental interest because of its extensive savannas and varied forests – the home of some of the largest and most diverse groups of indigenous Indians. This critical assessment of the nature and pace of agricultural advance into Roraima examines the range of strategies which have been proposed to cope with the inevitable development. With the conflict between preserving the natural environment and development still major issues for Brazil, this book remains as relevant now as when it was first published.
Download or read book The Amazon written by H. Sioli and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 762 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Amazon -that name was given to the biggest river on earth and is often used for the whole area of its basin too. This geographical region is currently referred to as Amazonia, thus emphasizing the peculiar character of its aquatic and terrestrial reaches. The Amazon embodied the dream of many a naturalist to explore what for a long time was a terra incognita. In recent years, however, Amazonia has emerged as a main centre for 'development' by some of the countries in which it lies and by foreign industrialized nations. The development projects and enterprises have aroused woridwide interest and have given rise to discussions on their aims and their consequences to the Amazonian nature. Limnological and ecological investigations in Amazonia started only about 40 years ago. The editor had the good fortune to partake in them from the very beginning. He spent his decisive years in Amazonia, and dedicated his life's work to that research and to that country and the Amazonian people. Nearing the end of his scicntific activities, hc is gratcful to bc ablc to summarizc in this book most of the knowledge we possess at present of Amazonian limnology and landscape ecology.
Book Synopsis Tropical Rain Forest: A Wider Perspective by : F.B. Goldsmith
Download or read book Tropical Rain Forest: A Wider Perspective written by F.B. Goldsmith and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: The international perspective for this book is the unprecedented level of concern over deforestation, recognized by the meeting of world leaders at the 1992 Earth Summit, in Rio do Janeiro, and culminating in the appoint ment of the Intergovernmental Panel on Forests (IPF), under the auspices of the UN Commission on Sustainable Development. The wide range of issues covered by the authors in this volume reflects the breadth of the interna tional debate, from national policies and activist campaigning, through eco nomic and social objectives, to the sustainable management of forest and soil resources. Since the conservation campaigns of the 1980s, the focus of international concern has widened from tropical rain forests to all forest formations, in all regions, with increased recognition of global values and common responsibil ities. However, while forest cover in some temperate countries is increasing, irrational deforestation, at historically unprecedented levels of damage to biodiversity and to other environmental values, remains most acute in tropi cal countries, where the need to use the natural resources for sustainable development is greatest, and the capability weakest. While accepting the urgency of the situation, and the need for greater coherence of action at a global level, the 1997 report of the IPF to the UN Commission emphasized the powers and responsibilities of national governments, and the importance of National Forest Programmes, but with the fuller participation of local communities, and with enhanced access to international assistance.
Book Synopsis Amazonia and Global Change by : Michael Keller
Download or read book Amazonia and Global Change written by Michael Keller and published by John Wiley & Sons. This book was released on 2013-05-02 with total page 1472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 186. Amazonia and Global Change synthesizes results of the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) for scientists and students of Earth system science and global environmental change. LBA, led by Brazil, asks how Amazonia currently functions in the global climate and biogeochemical systems and how the functioning of Amazonia will respond to the combined pressures of climate and land use change, such as Wet season and dry season aerosol concentrations and their effects on diffuse radiation and photosynthesis Increasing greenhouse gas concentration, deforestation, widespread biomass burning and changes in the Amazonian water cycle Drought effects and simulated drought through rainfall exclusion experiments The net flux of carbon between Amazonia and the atmosphere Floodplains as an important regulator of the basin carbon balance including serving as a major source of methane to the troposphere The impact of the likely increased profitability of cattle ranching. The book will serve a broad community of scientists and policy makers interested in global change and environmental issues with high-quality scientific syntheses accessible to nonspecialists in a wide community of social scientists, ecologists, atmospheric chemists, climatologists, and hydrologists.

Book Synopsis Saving the World by : Brett M. Bennett
Download or read book Saving the World written by Brett M. Bennett and published by Reaktion Books. This book was released on 2024-07-06 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: An illuminating history of the forgotten concept of climatic botany that underscores how vital forests are to our future. Saving the World tells the forgotten history of climatic botany, the idea that forests are essential for creating and recycling rain. Long before the specter of global warming, societies recognized that deforestation caused drastic climate shifts—as early as 1770, concerns over deforestation spurred legislation to combat human-induced climate change. Across the twentieth century, climatic botany experienced fluctuating fortunes, influenced by technological advancements and evolving meteorological theories. Remarkably, contemporary scientists are rediscovering the crucial role of forests in rainfall recycling, unaware of the long history of climatic botany. This enlightening book is essential reading for anyone passionate about conserving the world’s forests and preserving our climate for future generations.

Book Synopsis Amazonian Rain Forests by : Carl F. Jordan
Download or read book Amazonian Rain Forests written by Carl F. Jordan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: DEVELOPMENT AND DISTURBANCE IN AMAZON FORESTS Contrasting Impressions 6 2 The rain forests of the Amazon Basin cover approximately 5.8 x 10 km (Salati and Vose 1984). Flying over even just part of this basin, one gazes hour after hour upon this seemingly infinite blanket of green. The impression of immen sity is similar when viewed from the Amazon River itself, or from its tributar ies. From a hammock on the shaded deck of a riverboat, the immensity of the forest presents an incredible monotony as one view of the shoreline blends unnoticeably into another. From both perspectives, the overwhelming reaction to the sea of trees that stretches from horizon to horizon is a sense of the vastness of the rain forest. In September 1985, I got a different impression of the rain forest. Several students and I journeyed in a self-propelled car along the single-track railroad that stretches almost 1000 km from the Carajas iron ore mine in the rain forest of Para State, Brazil, all the way to Sao Luis on the coast (Fig. 1.1).
