Book Description
The wood-fired boiler at the Vermont State Hospital in Waterbury, Vermont was investigated in order to identify environmental and economic problems associated with increased use of wood as fuel. The investigators observed that the low amount of stack emissions contained particulates that were extremely effective light scatterers. An analysis of the entire system was performed in order to investigate the particulate growth and the conversion of gaseous material to particulates within the system. Initial findings indicate that a good deal of particulate formation takes place within and after the cyclone, thus rendering the cyclone somewhat ineffective in this system. Meteorological data were acquired in the vicinity of the experimental site. Background concentrations were measured using hi-vol samplers and a Tracer experiment was performed to indicate the direction of plume travel. These data were incorporated into the Los Alamos Visibility Model to simulate the actual appearance of the plume with a variety of boiler sizes. This simulation gives one an indication of how large a boiler, sited in this location, can be before the opacity of the plume becomes aesthetically offensive. An economic assessment of the wood burning activities at Waterbury and a number of other sites is included in this report.

Book Description
Forests are the dominant terrestrial ecosystem of Earth. They are distributed across the globe. Forests account for 75% of the gross primary productivity of the Earth's biosphere, and contain 80% of the Earth's plant biomass. Human society and forests influence each other in both positive and negative ways. Forests provide ecosystem services to humans. Forests can also impose costs, affect people's health, and interfere with tourist enjoyment. This publication presents reviews and research results on negative and positive human interference on forests, as well as ecology, management, governance, policy and economic issues. The book consists of four sections with 12 chapters derived from around the world.

Book Description
This book is written for scientists and practitioners interested in deepening their knowledge of the sustainable production of bioenergy from wood in tropical and sub-tropical countries. Utilising the value chain concept, this book outlines the necessary aspects for managing sustainable bioenergy production. A wide range of topics is covered including biomass localization, modelling and upscaling, production management in woodlands and plantations, and transport and logistics. Biomass quality and conversion pathways are examined in order to match the conversion technology with the available biomass. A section is dedicated to issues surrounding sustainability. The issues, covered in a life-cycle assessment of the bioenergy system, include socio-economic challenges, local effects on water, biodiversity, nutrient-sustainability and global impacts. Through this holistic approach and supporting examples from tropical and sub-tropical countries, the reader is guided in designing and implementing a value chain as the main management instrument for sustainable wood.

Book Description
How Wall Street, Chinese billionaires, oil sheiks, and agribusiness are buying up huge tracts of land in a hungry, crowded world. An unprecedented land grab is taking place around the world. Fearing future food shortages or eager to profit from them, the world’s wealthiest and most acquisitive countries, corporations, and individuals have been buying and leasing vast tracts of land around the world. The scale is astounding: parcels the size of small countries are being gobbled up across the plains of Africa, the paddy fields of Southeast Asia, the jungles of South America, and the prairies of Eastern Europe. Veteran science writer Fred Pearce spent a year circling the globe to find out who was doing the buying, whose land was being taken over, and what the effect of these massive land deals seems to be. The Land Grabbers is a first-of-its-kind exposé that reveals the scale and the human costs of the land grab, one of the most profound ethical, environmental, and economic issues facing the globalized world in the twenty-first century. The corporations, speculators, and governments scooping up land cheap in the developing world claim that industrial-scale farming will help local economies. But Pearce’s research reveals a far more troubling reality. While some mega-farms are ethically run, all too often poor farmers and cattle herders are evicted from ancestral lands or cut off from water sources. The good jobs promised by foreign capitalists and home governments alike fail to materialize. Hungry nations are being forced to export their food to the wealthy, and corporate potentates run fiefdoms oblivious to the country beyond their fences. Pearce’s story is populated with larger-than-life characters, from financier George Soros and industry tycoon Richard Branson, to Gulf state sheikhs, Russian oligarchs, British barons, and Burmese generals. We discover why Goldman Sachs is buying up the Chinese poultry industry, what Lord Rothschild and a legendary 1970s asset-stripper are doing in the backwoods of Brazil, and what plans a Saudi oil billionaire has for Ethiopia. Along the way, Pearce introduces us to the people who actually live on, and live off of, the supposedly “empty” land that is being grabbed, from Cambodian peasants, victimized first by the Khmer Rouge and now by crony capitalism, to African pastoralists confined to ever-smaller tracts. Over the next few decades, land grabbing may matter more, to more of the planet’s people, than even climate change. It will affect who eats and who does not, who gets richer and who gets poorer, and whether agrarian societies can exist outside corporate control. It is the new battle over who owns the planet.

Book Description
Natural and man-made changes in the environment create a very complex picture. This book analyzes this picture and provides snapshots of different areas of interest and to make suggestions for future work on cleaning and stabilizing the Earth's environment. Starting with conventional energy generation and moving on to renewable energies, this book analyzes and calculates their environmental impact and the lesser known aspects of their "cradle-to-grave" life cycle such as the irreversible environmental damage done during the manufacturing of solar and wind equipment and during the installation, operation, and decommissioning of large scale hydro, solar, and wind power plants.
