Book Description
Pilot Analysis of Global Ecosystems (PAGE): Coastal Ecosystems analyzes quantitative and qualitative information and develops selected indicators of the condition of the world's coastal ecosystems and marine fisheries. Specifically the study looks at measures that show the degree of human modification of coastal zone and what we know concerning five important goods and services provided by coastal ecosystems: filtering water, food, biodiversity, shoreline stabilization, and tourism. Results from the PAGE analysis show that human activities have extensively altered coastal ecosystems worldwide. Nearly 30 percent of the land area in the world's coastal ecosystems had already been extensively altered or destroyed by growing demand for housing, industry, and recreation. Globally, the number of people living within 100 km of the coast increased from roughly 2 billion in 1990 to 2.2 billion in 1995 four out of every ten people in the world. As coastal and inland populations continue to grow, their impacts in terms of pollutant loads and the development and conversion of coastal habitats can be expected to grow as well. Nutrient pollution has increased dramatically this century due to greater use of fertilizers, growth in quantities of domestic and industrial sewage, and increased aquaculture, which releases considerable amounts of waste directly into the water. Increasing fishing pressure have left many major fish stocks depleted or in decline. Global climate change may compound other pressures on coastal ecosystems through the additional effects of warmer ocean temperatures, altered ocean circulation patterns, changing storm frequency, and rising sea levels.

Book Description
The aim of Ecosystem Services and Global Ecology is to give an overview and report from the frontiers of research of this important and interesting multidisciplinary area. Ecosystem services as a concept plays a key role in solving global environmental and human ecological crises and associated other problems, especially today when the sixth major extinction event of the history of the biosphere is in progress, and humanity can easily become a victim of it. Human activity is rapidly transforming the surface of the Earth, its biosphere, atmosphere, soil, and water resources. Ecological processes happen over a long time scale, thus damage caused by human activity will be perceptible after decades or even centuries. We hope that our book will be interesting and useful for researchers, lecturers, students, and anyone interested in this field.

Book Description
World Resources 2000-2001, People and Ecosystems: The Fraying Web of Life focuses on the critical link between ecosystems and people and provides an overview of current global environmental and economic trends using hundreds of indicators in more than 150 countries. Until now there has not been a comprehensive, formalised process to assess human damage to our ecosystems, to establish a baseline for future actions, or to disseminate information that would aid the formulation of better policies world-wide. This book is the first reliable, comprehensive base of evidence for taking stock and taking care of the world's diverse ecosystems. • deals with the critical issues that focus on the link between ecosystems and people • highlights the goods and services that ecosystems provide and illustrates the benefits of a better understanding and better management of the planet's natural wealth • reports on pilot studies by leading scientists and international institutions assessing the state of the world's ecosystems - forests, croplands, grasslands, freshwater systems and coastal areas • increases the understanding of human dependence on nature • raises awareness of environmental threats • provides examples of wise stewardship from all corners of the globe • focuses on four main issues: population and human well-being, food and water security, consumption, energy and wastes, trace emissions since the Kyoto protocol • gives data tables for more than 150 countriesIt demonstrates the power of information and new digital technologies to transform the way we interact with our environment and is particularly important for environmentalists, scientists, professionals, journalists, policy-makers and students. This special Millennium Edition of the World Resources Institute's biennial report published by Elsevier Science in September 2000 in partnership with the World Resources Institute, the UN Environment Program, the UN Development Programme and the World Bank.

Book Description
The Earth System may be the most complex entity that ever emerged in our galaxy and the contemporary process of 'globalisation' may be the most intricate dynamics that will ever pervade that entity: it is the interactive co-evolution of millions of technological, cultural, economic, social and environmental trends at all conceivable spatiotemporal scales that brings about the present fundamental transformation of humanity’s way of life. In this text the authors make the heroic effort to tame the complexity of modern planetary development by the intellectual concept of 'transition'. In this work, four major issues are discussed that are of global importance: developments related to two of our key natural resources; water and biodiversity; the health of human populations; and the developments related to global tourism.

Book Description
Because of the major opportunities and risks associated with it, and the complexity of the subject, bioenergy policy has in a short time become a challenging political task for regulators and planners – a task that can only be accomplished through worldwide cooperation and the creation of an international framework. This book's central message is that the sustainable potential of bioenergy, which can be tapped all over the world, should be utilized – provided that threats to sustainability are avoided. In particular, the use of bioenergy must not endanger food security or the goals of nature conservation and climate change mitigation.

Book Description
Environmental Management of Air, Water, Agriculture, and Energy brings together the most current state of knowledge on four major elements for sustaining life on planet Earth: air, water, food, and energy. It examines how green technology aids in mitigating the global water, energy, and climate change crises, including the use of electrostatic force and green infrastructure. The concepts of underwater vegetation and aquatic cultivation, as well as vertical farms, are presented to spark discussion on emerging water-energy-food nexus lessons, experiences, and opportunities. This book takes a comprehensive global-scale approach to examining potential future environmental scenarios and outcomes. Features: Analyzes the most recent research findings in each of the areas covered Synthesizes the state-of-the-art understanding Recommends ways to strive forward and to shape future research Serves as an educational tool for educators and students Supported by detailed examples and case studies, this book serves not only as an up-to-date source of information for environmental experts and researchers in the field, but also as an educational tool for relevant undergraduate and graduate courses. It is also suitable for industry professionals concerned with preserving planet Earth for generations to come.
