Book Description
The Amazon basin is a key component of the global carbon cycle. Not only is the old-growth rainforests in the basin huge carbon storage with about 120 billion metric tons of carbon in their biomass, but they also process annually twice the rate of global anthropogenic fossil fuel emissions through respiration and photosynthesis. In addition, the basin is the largest global repository of biodiversity and produces about 20 percent of the world s flow of fresh water into the oceans. Despite the large CO2 efflux from recent deforestation, the Amazon rainforest is still considered to be a net carbon sink or reservoir because vegetation growth on average exceeds mortality. However, current climate trends and human-induced deforestation may be transforming forest structure and behavior. Amazon forest dieback would be a massive event, affecting all life-forms that rely on this diverse ecosystem, including humans, and producing ramifications for the entire planet. Clearly, with changes at a global scale at stake, there is a need to better understand the risk, and dynamics of Amazon dieback. Therefore, the purpose of the book is to assist in understanding the risk, process and dynamics of potential Amazon dieback and its implications.

Book Description
“The seminal book on global poverty and hunger . . . How rapacious speculators and complicit bureaucrats are starving a billion people” (Wenonah Hauter, executive director of Food & Water Watch and author of Foodopoly). Few people know that world hunger was very nearly eradicated in our lifetimes. In the past five years, however, widespread starvation has suddenly reappeared, and chronic hunger is a major issue on every continent. In an extensive investigation of this disturbing shift, Jean Ziegler—one of the world’s leading food experts—lays out in clear and accessible terms the complex global causes of the new hunger crisis. Ziegler’s wide-ranging and fascinating examination focuses on how the new sustainable revolution in energy production has diverted millions of acres of corn, soy, wheat, and other grain crops from food to fuel. The results, he shows, have been sudden and startling, with declining food reserves sending prices to record highs and a new global commodities market in ethanol and other biofuels gobbling up arable lands in nearly every continent on earth. Like Raj Patel’s pioneering Stuffed and Starved, Betting on Famine will enlighten the millions of Americans concerned about the politics of food at home—and about the forces that prevent us from feeding the world’s children. “In this devastating book, [Ziegler] describes the horrors of food insecurity, the callousness of ‘crusaders of neoliberalism’ who control food and land access, and the individuals and grassroots organizations fighting for subsistence farmers and the right to food.” —Publishers Weekly (starred review) “Passionate, well-researched, objective, and illuminating . . . When we close this book, indignant, we know that those who die of hunger are victims of money and power.” —L’Express

Book Description
Released every three years since March 2003, the United Nations World Water Development Report (WWDR), a flagship UN-Water report published by UNESCO, has become the voice of the United Nations system in terms of the state, use and management of the world's freshwater resources. The report is primarily targeted at national decision-makers and water resource managers, but is also aimed at educating and informing a broader audience, from governments to the private sector and civil society. It underlines the important roles water plays in all social, economic and environmental decisions, highlighting policy implications across various sectors, from local and municipal to regional and international levels. Similarly to the first two editions, this report includes a comprehensive and up-to-date assessment of several key challenge areas, such as water for food, energy and human health, and governance challenges such as institutional reform, knowledge and capacity-building, and financing, each produced by individual UN agencies.

Book Description
This book intends to be an alert to the fact that the curve measuring environmental costs against the economic benefits of capitalism has irreversibly entered into a negative phase. The prospect of an environmental collapse has been evidenced by the sciences and the humanities since the 1960s. Today, it imposes its urgency. This collapse differs from past civilizations in that it is neither local nor just civilizational. It is global and occurs at the broadest level of the biosphere, accelerated by the convergence of different socio-environmental crises, such as: Earth energy imbalance, climate change and global warming Sea-level rise Decrease and degradation of forests Collapse of terrestrial and aquatic biodiversity Floods, droughts, wildfires, and extreme weather events Degradation of soils and water resources Increase in pollution caused by fossil fuels and coal Increase in waste production and industrial intoxication The book is divided in two parts. In the first part it presents a comprehensive review of scientific data to show the already visible effects of each of the different environmental crises and its consequences to human life on Earth. In the second part, Luiz Marques critically discusses what he calls the three concentric illusions that prevent us from realizing the gravity of the current socio-environmental crises: the illusion of a sustainable capitalism, the illusion that economic growth is still capable of providing more well-being and the anthropocentric illusion. Finally, Marques argues that "fitting" back into the biosphere will only be possible if we dismantle the expansive socioeconomic gear that has shaped our societies since the 16th century by moving from a Social Contract to a Natural Contract, which takes into account the whole biosphere. According to him, the future society will be post-capitalist or it will not be a complex society, and even perhaps, we must fear, no society at all. “This book is backed up with the latest and best science and has made the complexities understandable for the average reader, all in a context of hope for the future.” - William J. Ripple, PhD, Distinguished Professor of Ecology, Director of the Alliance of World Scientists, Oregon State University

Book Description
This synthesis focuses on estimates of biodiversity change as projected for the 21st century by models or extrapolations based on experiments and observed trends. The term "biodiversity" is used in a broad sense as it is defined in the Convention on Biological Diversity to mean the abundance and distributions of and interactions between genotypes, species, communities, ecosystems and biomes. This synthesis pays particular attention to the interactions between biodiversity and ecosystem services and to critical "tipping points" that could lead to large, rapid and potentially irreversible changes. Comparisons between models are used to estimate the range of projections and to identify sources of uncertainty. Experiments and observed trends are used to check the plausibility of these projections.

Book Description
Why, when so many people understand the severity of environmental problems, is progress so slow and sustainability such a distant goal? What gets in the way? Perhaps you have immediately thought of several barriers. In Obstacles to Environmental Progress, Peter Schulze identifies 18 practical obstacles that routinely and predictably hinder U.S. progress on existing environmental problems. The obstacles apply to problems small and large and, in most cases, regardless of whether an issue is controversial. Though the book focuses on the U.S., most of the obstacles pertain elsewhere as well. The obstacles fall into three categories: scientific challenges to anticipating and detecting problems; political and economic factors that interfere with responding; and obstacles to effective responses. While all the obstacles are predictable and common, they have not been systematically studied as related phenomena, perhaps because they span a wide range of academic disciplines. In practice, they often arise as surprises that are then addressed in an ad hoc manner. Might they be better understood and thus more readily anticipated and overcome or avoided? The book seeks to hasten environmental progress by forewarning and thus forearming those who are striving or will soon be striving for environmental progress, and by drawing scholarly attention to the obstacles as a set of related phenomena to systematically understand and more quickly overcome. Praise for Obstacles to Environmental Projects ‘I have never come across another book that gives students such an accessible and helpful guide to the broad scope of the challenges facing an environmentally sound and sustainable future.’ – Al Wurth, Lehigh University

Book Description
The 8th Edition of the UN Environment Programme flagship report, The UNEP Year Book 2011, examines global emerging issues and provides the latest environmental science. it also highlights major environmental events and developments over the past year, and presents the most recent data and indicator trends. The ocean has become a global repository for much of the waste we produce. Scientists are concerned that plastic debris in the ocean can transport toxic substances which may end up in the food chain, causing potential harm to ecosystems and human health. The Year Book also explores the wider implications of the use of phosphorus in food production. Phosphorus is an essential nutrient whose supply is limited. Since demand for fertilizer in agriculture rocketed in the 20th century, large amounts of phosphorus are flowing into the environment. New perspectives are also emerging on how biodiversity conservation can be integrated in forest management. Forests are receiving increasing attention, not least because of their role in climate change mitigation. Halting loss of forest biodiversity is essential if forests are to adapt to mounting pressures, including climate change and pest outbreaks. The Year Book's overview of events and developments during 2010 shows how cutting edge science reveals new opportunities to mitigate climate change while improving air quality. Stimulated by technological innovation and green investments, renewable energy supply is growing rapidly. This and other developments are summarized in key environmental indicators that present the latest data and trends For The global environment.

Book Description
This Intergovernmental Panel on Climate Change Special Report (IPCC-SREX) explores the challenge of understanding and managing the risks of climate extremes to advance climate change adaptation. Extreme weather and climate events, interacting with exposed and vulnerable human and natural systems, can lead to disasters. Changes in the frequency and severity of the physical events affect disaster risk, but so do the spatially diverse and temporally dynamic patterns of exposure and vulnerability. Some types of extreme weather and climate events have increased in frequency or magnitude, but populations and assets at risk have also increased, with consequences for disaster risk. Opportunities for managing risks of weather- and climate-related disasters exist or can be developed at any scale, local to international. Prepared following strict IPCC procedures, SREX is an invaluable assessment for anyone interested in climate extremes, environmental disasters and adaptation to climate change, including policymakers, the private sector and academic researchers.
