Pilot Analysis of Global Ecosystems


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.




World Resources 2000-2001


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.

Links Between Biodiversity Conservation, Livelihoods and Food Security


Book Description

The global use of wild animals for meat is now the primary illegal activity in many protected areas, and growing human populations and a lack of livelihood options suggest that demand for wild meat is likely to continue to rise. This Occasional Paper contains the background information presented to participants at a workshop jointly organized by IUCN, FAO and TRAFFIC in Yaoundé, Cameroon. The workshop aimed to forge functional links among the various stakeholders concerned with the unsustainable use of wild fauna for food, and it contains the communiqué and a summary of the discussions related to problems and solutions.




Ecosystems and Human Well-being


Book Description

Ecosystems and Human Well-Being is the first product of the Millennium Ecosystem Assessment, a four-year international work program designed to meet the needs of decisionmakers for scientific information on the links between ecosystem change and human well-being. The book offers an overview of the project, describing the conceptual framework that is being used, defining its scope, and providing a baseline of understanding that all participants need to move forward. The Millennium Assessment focuses on how humans have altered ecosystems, and how changes in ecosystem services have affected human well-being, how ecosystem changes may affect people in future decades, and what types of responses can be adopted at local, national, or global scales to improve ecosystem management and thereby contribute to human well-being and poverty alleviation. The program was launched by United National Secretary-General Kofi Annan in June 2001, and the primary assessment reports will be released by Island Press in 2005. Leading scientists from more than 100 nations are conducting the assessment, which can aid countries, regions, or companies by: providing a clear, scientific picture of the current sta




Ecosystem Services and Global Ecology


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.




Remote Sensing of Aquatic Coastal Ecosystem Processes


Book Description

The aquatic coastal zone is one of the most challenging targets for environmental remote sensing. Properties such as bottom reflectance, spectrally diverse suspended sediments and phytoplankton communities, diverse benthic communities, and transient events that affect surface reflectance (coastal blooms, runoff, etc.) all combine to produce an optical complexity not seen in terrestrial or open ocean systems. Despite this complexity, remote sensing is proving to be an invaluable tool for "Case 2" waters. This book presents recent advances in coastal remote sensing with an emphasis on applied science and management. Case studies of the operational use of remote sensing in ecosystem studies, monitoring, and interfacing remote sensing/science/management are presented. Spectral signatures of phytoplankton and suspended sediments are discussed in detail with accompanying discussion of why blue water (Case 1) algorithms cannot be applied to Case 2 waters. Audience This book is targeted for scientists and managers interested in using remote sensing in the study or management of aquatic coastal environments. With only limited discussion of optics and theory presented in the book, such researchers might benefit from the detailed presentations of aquatic spectral signatures, and to operational management issues. While not specifically written for remote sensing scientists, it will prove to be a useful reference for this community for the current status of aquatic coastal remote sensing.
