Book Description
Trees have been around for more than 370 million years, and today there are about 80 thousand species of them, occupying 3.5 billion hectares worldwide, including 250 million ha of commercial plantations. While forests can provide tremendous environmental, social, and economic benefits to nations, they also affect the hydrologic cycle in different ways. As the demand for water grows and local precipitation patterns change due to global warming, plantation forestry has encountered an increasing number of water-related conflicts worldwide. This document provides a country-by-country summary of the current state of knowledge on the relationship between forest management and water resources. Based on available research publications, the Editor-in-Chief of this document contacted local scientists from countries where the impact of forest management on water resources is an issue, inviting them to submit a chapter.

Book Description
Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

Book Description
A unique approach to the challenges of complex environmental systems Environmental Transport Processes, Second Edition provides much-needed guidance on mass transfer principles in environmental engineering. It focuses on working with uncontrolled conditions involving biological and physical systems, offering examples from diverse fields, including mass transport, kinetics, wastewater treatment, and unit processes. This new edition is fully revised and updated, incorporating modern approaches and practice problems at the end of chapters, making the Second Edition more concise, accessible, and easy to use. The book discusses the fundamentals of transport processes occurring in natural environments, with special emphasis on working at the biological physical interface. It considers transport and kinetics in terms of systems that involve microorganisms, along with in-depth coverage of particles, size spectra, and calculations for particles that can be considered either spheres or fractals. The book's treatment of particles as fractals is especially unique and the Second Edition includes a new section on exoelectrogenic biofilms. It also addresses dispersion in natural and engineered systems unlike any other book on the subject. Readers will learn to tackle with confidence complex environmental systems and make transport calculations in heterogeneous environments with mixtures of chemicals.

Book Description
Green nanotechnology has two goals: producing nanomaterials and products without harming the environment or human health, and producing nanoproducts that provide solutions to environmental problems. It uses existing principles of green chemistry and green engineering to make nanomaterials and nanoproducts without toxic ingredients, at low temperatures using less energy and renewable inputs wherever possible, and using lifecycle thinking in all design and engineering stages. The production and process aspects of green nanotechnology involve both making nanomaterials in a more environmentally benign fashion and using nanomaterials to make current chemical processes more environmentally acceptable. This book contains information about advanced nanomaterials that can be produced without harming the environment or human health. This encompasses the production of nanomaterials without environmental toxicity, at room temperature and with the use of renewable energy sources. The book contains the descriptions and results of theoretical and experimental researches in the field of environment friendly nanotechnology carried out over the past decade by the scientific team of company Polymate Ltd.-International Nanotechnology Center (Israel) under leadership of Prof. O. Figovsky. Developments of the Company have been used in industry and agriculture and protected by more than 25 patents of USA, Germany and Russia.

Book Description
Sustainable Development: Constraints and Opportunities contains a selection of the author's speeches made between 1982 and 1986. During this 5-year period knowledge of environment-development relationships has grown considerably, and this evolving perception can be discerned in his statements spanning those years. Taken together, the common thread binding all the speeches is the fact that long-term development can only be achieved through sound environmental management, that is, sustainable development, which is the title of this book. The speeches included in this volume were delivered in the author's capacity as the Executive Director of the United Nations Environment Programme (UNEP). They thus cover primarily broad areas of interest of UNEP's programs and policies. Key topics discussed include environmental protection; disarmament and the environment; environmental information for engineers; the impact of human settlements on the environment; environmental management in the Gulf; the causes, effects, and prevention of desertification; and the environmental impact assessment process.

Book Description
Chocolate - the very word conjures up a hint of the forbidden and a taste of the decadent. Yet the story behind the chocolate bar is rarely one of luxury. From the thousands of children who work on plantations to the smallholders who harvest the beans, Chocolate Nations reveals the hard economic realities of our favourite sweet. This vivid and gripping exploration of the reasons behind farmer poverty includes the human stories of the producers and traders at the heart of the West African industry. Orla Ryan shows that only a tiny fraction of the cash we pay for a chocolate bar actually makes it back to the farmers, and sheds light on what Fair Trade really means on the ground. Provocative and eye-opening, Chocolate Nations exposes the true story of how the treat we love makes it on to our supermarket shelves.

Book Description
João Rodrigues sailed from Portugal to Japan in 1577, and there entered the Jesuit novitiate and was ordained priest. He met Toyotomi Hideyoshi, the virtual ruler of Japan, in 1591, and from that time became the missionaries' spokesman in dealings with Japanese authorities. He was also involved in negotiations concerning the bulk sale of Chinese silk in Japan, and commercial and political rivalries led to his eventual expulsion from the country in 1610. Rodrigues spent the rest of his life in Macao and the interior of China, dying in 1633. Renowned for his fluency in spoken Japanese, Rodrigues earned a place in the history of Japanese-European cultural relations by publishing a Portuguese grammar of the Japanese language (Nagasaki, 1604-1608), followed by a revised edition (Macao, 1620). Both works provide valuable information about Japanese spoken in the early 17th century. Rodrigues also provided the draft used as a basis for the official history of the Christian mission in Japan. To set this work in context he composed two books on various aspects of Japanese life - geography, customs, clothing, science, architecture, art, and, above all, the tea ceremony. The present volume provides annotated translations of these two books, together with an introduction assessing Rodrigues's contribution to the understanding of Japanese life and culture in the early 17th century.
