Global ecosystem changes are influenced by a combination of natural and anthropogenic factors. Ongoing changes in rainfall, temperature, and carbon dioxide in the atmosphere can affect natural or managed vegetation, such as forest, grassland, or farmland. Moreover, anthropogenic pressures, such as forest clearing, cattle grazing, increasing infrastructural development, intensive management, and expansion of cropland, can contribute to ecosystem degradation. This collection presents a wide range of studies examining natural and anthropogenic drivers in diverse ecosystems in Africa, Asia, and North America.

During the summer of 1987, a series of discussions I was held at the International Institute for Applied Systems Analysis (nASA) in Laxenburg, Austria, to plan a study of global vegetation change. The work was aimed at promoting the Interna tional Geosphere-Biosphere Programme (IGBP), sponsored by the International Council of Scientific Unions (lCSU), of which nASA is a member. Our study was designed to provide initial guidance in the choice of approaches, data sets and objectives for constructing global models of the terrestrial biosphere. We hoped to provide substantive and concrete assistance in formulating the working plans of IGBP by involving program planners in the development and application of models which were assembled from available data sets and modeling ap proaches. Recent acceptance of the "nASA model" as the starting point for endeavors of the Global Change and Terrestrial Ecosystems Core Project of the IGBP suggests we were successful in that aim. The objective was implemented by our initiation of a mathematical model of global vegetation, including agriculture, as defined by the forces which control and change vegetation. The model was to illustrate the geographical consequences to vegetation structure and functioning of changing climate and land use, based on plant responses to environmental variables. The completed model was also expected to be useful for examining international environmental policy responses to global change, as well as for studying the validity of IIASA's experimental approaches to environmental policy development.

This book focuses on some significant progress in vegetation dynamics and their response to climate change revealed by remote sensing data. The development of satellite remote sensing and its derived products offer fantastic opportunities to investigate vegetation changes and their feedback to regional and global climate systems. Special attention is given in the book to vegetation changes and their drivers, the effects of extreme climate events on vegetation, land surface albedo associated with vegetation changes, plant fingerprints, and vegetation dynamics in climate modeling.

Global climate change challenges ecologists to synthesize what we know to solve a problem with deep historical roots in our discipline. In ecology, the question, “How do terrestrial ecosystems interact with the other earth systems to produce planetary change?” has sufficient depth to be the focal challenge. This central question is sharpened further as the changes that we may be manifesting upon our planet’s systems of land, sea, air and ice can have potential consequences for the future of human civilization. This book provides the depth of the history of global ecology and reviews the breadth of the ideas being studied today. Each chapter starts with a brief narrative about a scientist whose work traces forward into today’s issues in global ecosystems. The discussions are framed in a growing realization that we may be altering the way our planet functions almost before we have gained the necessary knowledge of how it works at all.

This major new book presents a collection of essays by leading authorities who address the current state of knowledge. The chapters bring together the early results of an international scientific research program designed to address what will happen to our ability to produce food and fiber, and what effects there will be on biological diversity under rapid environmental change. This book addresses how these changes to terrestrial ecosystems will feed back to further environmental change. International in scope, this state-of-the-art assessment will interest policymakers, students and scientists interested in global change, climate change and biodiversity. Special features include descriptions of a dynamic global vegetation model, developing generic crop models and a special section on the emerging discipline of global ecology.

Natural and human-induced changes in Earth's interior, land surface, biosphere, atmosphere, and oceans affect all aspects of life. Understanding these changes requires a range of observations acquired from land-, sea-, air-, and space-based platforms. To assist NASA, NOAA, and USGS in developing these tools, the NRC was asked to carry out a "decadal strategy" survey of Earth science and applications from space that would develop the key scientific questions on which to focus Earth and environmental observations in the period 2005-2015 and beyond, and present a prioritized list of space programs, missions, and supporting activities to address these questions. This report presents a vision for the Earth science program; an analysis of the existing Earth Observing System and recommendations to help restore its capabilities; an assessment of and recommendations for new observations and missions for the next decade; an examination of and recommendations for effective application of those observations; and an analysis of how best to sustain that observation and applications system.

Vegetation change has been observed across Arctic and boreal regions. Studies have often documented large-scale greening trends, but they have also identified areas of browning or shifts between greening and browning over varying spatial extents and time periods. At the same time, though, there are large portions of these ecosystems that have not exhibited measurable trends in greening or browning. These findings have fueled many questions about the drivers of vegetation dynamics, how trends are measured, and potential implications of vegetation change at local to global scales. In December 2018, the National Academies of Sciences, Engineering, and Medicine, convened a workshop to discuss opportunities to improve understanding of greening and browning trends and drivers and the implications of these vegetation changes. The discussions included a close look at many of the methodological approaches used to evaluate greening and browning, as well as exploration of newer technologies that may help advance the science. This publication summarizes the presentations and discussions from the workshop.

This book presents recent estimates on the rate of change of major land classes. Aggregated globally, multiple impacts of local land changes are shown to significantly affect central aspects of Earth System functioning. The book offers innovative developments and applications in the fields of modeling and scenario construction. Conclusions are also drawn about the most pressing implications for the design of appropriate intervention policies.
