Book excerpt: Excerpt from A Flora of Manila There are definitely known from the Philippines at the present time about 6,500 species of flowering plants and vascular cryptogams, distributed into about 1,450 genera, in 200 families. Many of the species are of very local occurrence, while others are confined to medium and higher altitudes in the mountains, and are hence never seen by the average resident of the Archipelago. The flora of the coastal region, especially of the populated areas, is remarkably uniform, practically the same forms being found in and about such towns as Zamboanga, Cebu, Iloilo, Aparri, etc., as are found about Manila, so that for all practical purposes a flora of the vicinity of Manila is also a nearly complete flora for most inhabited regions at low altitudes in all parts of the Archipelago. Accordingly while most of the plants encountered in the settled areas at low altitudes will be found to be described in the present work, it will be found to be of little value for the determination of specimens collected in the forests and on the mountains. In compiling this work an attempt has been made to include all the species of vascular cryptogams and flowering plants growing naturally within the area selected, as well as most of the cultivated forms, both of Philippine and of foreign origin. The area covered extends from a point north of Manila on the bay shore at Malabon, inland through Balintuac, San Francisco del Monte etc., to Pasig, thence to the town of Paranaque on the bay shore south of Manila, covering approximately 100 square kilometers (about 40 square miles). No part of the area exceeds an altitude of 50 meters, and no part of it approaches primeval conditions, the vegetation of the entire region having been profoundly altered by the presence of man. This "Flora" is based on botanical material preserved in the herbarium of the Bureau of Science, supplemented by an extensive series of notes covering a period of exploration of the area extending over eighteen months. Undoubtedly future intensive exploration will add a considerable number of species to the list of indigenous ones, while the list of introduced and cultivated species is being very rapidly increased. Scattered individuals of any species found in neighboring provinces at low altitudes are to be expected within our area, and as a matter of fact a considerable number of species are included in the present work on the basis of single plants observed within the region covered by it. In early botanical works, various monographs etc., many Philippine species are credited to the Archipelago as having been collected in Manila; very many of these references are erroneous, the term Manila having been used more or less synonymously with the Philippines. Most of the species so referred to were collected in regions remote from the city, and very many of them on other islands than Luzon. No species has been included unless specimens have been seen from the area selected. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: The growing problem of changing environmental conditions caused by climate destabilization is well recognized as one of the defining issues of our time. The root problem is greenhouse gas emissions, and the fundamental solution is curbing those emissions. Climate geoengineering has often been considered to be a "last-ditch" response to climate change, to be used only if climate change damage should produce extreme hardship. Although the likelihood of eventually needing to resort to these efforts grows with every year of inaction on emissions control, there is a lack of information on these ways of potentially intervening in the climate system. As one of a two-book report, this volume of Climate Intervention discusses albedo modification - changing the fraction of incoming solar radiation that reaches the surface. This approach would deliberately modify the energy budget of Earth to produce a cooling designed to compensate for some of the effects of warming associated with greenhouse gas increases. The prospect of large-scale albedo modification raises political and governance issues at national and global levels, as well as ethical concerns. Climate Intervention: Reflecting Sunlight to Cool Earth discusses some of the social, political, and legal issues surrounding these proposed techniques. It is far easier to modify Earth's albedo than to determine whether it should be done or what the consequences might be of such an action. One serious concern is that such an action could be unilaterally undertaken by a small nation or smaller entity for its own benefit without international sanction and regardless of international consequences. Transparency in discussing this subject is critical. In the spirit of that transparency, Climate Intervention: Reflecting Sunlight to Cool Earth was based on peer-reviewed literature and the judgments of the authoring committee; no new research was done as part of this study and all data and information used are from entirely open sources. By helping to bring light to this topic area, this book will help leaders to be far more knowledgeable about the consequences of albedo modification approaches before they face a decision whether or not to use them.

Download or read book Crop Stress and its Management Perspectives and Strategies written by B. Venkateswarlu and published by Springer Science & Business Media. This book was released on 2011-11-22 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crops experience an assortment of environmental stresses which include abiotic viz., drought, water logging, salinity, extremes of temperature, high variability in radiation, subtle but perceptible changes in atmospheric gases and biotic viz., insects, birds, other pests, weeds, pathogens (viruses and other microbes). The ability to tolerate or adapt and overwinter by effectively countering these stresses is a very multifaceted phenomenon. In addition, the inability to do so which renders the crops susceptible is again the result of various exogenous and endogenous interactions in the ecosystem. Both biotic and abiotic stresses occur at various stages of plant development and frequently more than one stress concurrently affects the crop. Stresses result in both universal and definite effects on plant growth and development. One of the imposing tasks for the crop researchers globally is to distinguish and to diminish effects of these stress factors on the performance of crop plants, especially with respect to yield and quality of harvested products. This is of special significance in view of the impending climate change, with complex consequences for economically profitable and ecologically and environmentally sound global agriculture. The challenge at the hands of the crop scientist in such a scenario is to promote a competitive and multifunctional agriculture, leading to the production of highly nourishing, healthy and secure food and animal feed as well as raw materials for a wide variety of industrial applications. In order to successfully meet this challenge researchers have to understand the various aspects of these stresses in view of the current development from molecules to ecosystems. The book will focus on broad research areas in relation to these stresses which are in the forefront in contemporary crop stress research.

This book was released on 2011-06-07 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Issues In Agroecology – Present Status and Future Prospectus not only reviews aspects of ecology, but the ecology of sustainable food production systems, and related societal and cultural values. To provide effective communication regarding status and advances in this field, this series connects with many disciplines such as sociology, anthropology, environmental sciences, ethics, agriculture, economics, ecology, rural development, sustainability, policy and education, and integrations of these general themes so as to provide integrated points of view that will help lead to a more sustainable construction of values than conventional economics alone. Such designs are inherently complex and dynamic, and go beyond the individual farm to include landscapes, communities, and biogeographic regions by emphasizing their unique agricultural and ecological values, and their biological, societal, and cultural components and processes.
Download or read book The Ash Warriors written by C. R. Anderegg and published by Department of the Air Force. This book was released on 2000 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: In November 1991 the American flag was lowered for the last time at Clark Air Base in the Philippines. This act brought to an end American military presence in the Philippines that extended back over 90 years. It also represented the final act in a drama that began with the initial rumblings in April of that year of the Mount inatubo volcano, located about nine miles to the east of Clark. This book tells the remarkable story of the men and women of the Clark community and their ordeal in planning for and carrying out their evacuation from Clark in face of the impending volcanic activity. It documents the actions of those who remained on the base during the series of Mount Pinatubo' s eruptions, and the packing out of the base during the subsequent months. This is the story of the Ash Warriors, those Air Force men and women who carried out their mission in the face of an incredible series of natural disasters, including volcanic eruption, flood, typhoons, and earthquakes, all of which plagued Clark and the surrounding areas during June and July 1991.
