Global change involves complex and far-reaching variations in the Earth’s systems, and satellite observations have been widely used in global change studies. Over the past five decades, Earth observation has developed into a comprehensive system that can conduct dynamic monitoring of the land, the oceans and the atmosphere at the local, regional and even global scale. At the same time, although a large number of Earth observation satellites have been launched, very few of them are used in global change studies. The lack of scientific satellite programs greatly hinders research on global change. This book proposes using a series of global change scientific satellites to establish a scientific observation grid for global environmental change monitoring from space, and offers the first comprehensive review of lunar-based Earth observation. These scientific satellites could provide not only basic datasets but also scientific support in facilitating advances in international global change research.

This publication is part of a two volume set which builds upon previous World Bank research into the causes and characteristics of civil war onset, particularly the model developed by Paul Collier and Anke Hoeffler regarding the relationship between violent political conflict and economic development. This volume considers the variables identified in the Collier-Hoeffler model and applies them to a set of case studies from a range of African countries, and then goes on to trace the process of conflict escalation in order to draw conclusions as to why civil war is likely to occur. The publication seeks to advance theoretical and empirical knowledge of civil war, in order to help further the objective of developing appropriate policy interventions. Another volume with case studies from a range of non-African countries is available separately (ISBN 0821360493).

The federal government is running huge budget deficits, spending too much, and heading toward a financial crisis. Federal spending soared under President George W. Bush, and the costs of programs for the elderly are set to balloon in coming years. Hurricane Katrina has made the federal budget situation even more desperate. In Downsizing the Federal Government Cato Institute budget expert Chris Edwards provides policymakers with solutions to the growing federal budget mess. Edwards identifies more than 100 federal programs that should be terminated, transferred to the states, or privatized in order to balance the budget and save hundreds of billions of dollars. Edwards proposes a balanced reform package of cuts to entitlements, domestic programs, and excess defense spending. He argues that these cuts would not only eliminate the deficit, but also strengthen the economy, enlarge personal freedom, and leave a positive fiscal legacy for the next generation. Downsizing the Federal Government discusses the systematic causes of wasteful spending, and it overflows with examples of federal programs that are obsolete and mismanaged. The book examines the budget process and shows how policymakers act contrary to the interests of average Americans by favoring special interests.

Earth Observation interacts with space, remote sensing, communication, and information technologies, and plays an increasingly significant role in Earth related scientific studies, resource management, homeland security, topographic mapping, and development of a healthy, sustainable environment and community. Geospatial Technology for Earth Observation provides an in-depth and broad collection of recent progress in Earth observation. Contributed by leading experts in this field, the book covers satellite, airborne and ground remote sensing systems and system integration, sensor orientation, remote sensing physics, image classification and analysis, information extraction, geospatial service, and various application topics, including cadastral mapping, land use change evaluation, water environment monitoring, flood mapping, and decision making support. Geospatial Technology for Earth Observation serves as a valuable training source for researchers, developers, and practitioners in geospatial science and technology industry. It is also suitable as a reference book for upper level college students and graduate students in geospatial technology, geosciences, resource management, and informatics.
