Global Environment Change Remote Sensing And Gis Perspectives

Geosphere-biosphere interaction of certain elements and compounds is a major factor in global environmental change. This guide to the role of geographical monitoring in ecosystem modelling contains papers presented at the International Geographical Union Seminar on monitoring geosystems.

The major causes of global environmental changes are various anthropogenic activities, not only those of present but also the integrated past activities. However, the interaction between man-environment system has not been understood sufficiently. The previous studies of monitoring of ongoing global environmental changes have paid little attention to socio-economic dimensions of anthropogenic activities which have induced various types of serious environmental changes. Land use forms a major element of terrestrial ecosystem modified by man and there is a growing concern in its disastrous change. In the above context, the emerging Remote Sensing and Geographic Information System help to strengthen the capacity of existing national and sub-regional institutions in the management and access to delivery of environment and natural resources information and data to support decision making process. Building effective bridges between scholars from various parts of the world is one of the most important tasks in this context. Increasing co-operation between researchers from advanced industrial nations and Third World countries is of particular importance. In order to achieve these goals, the International Geographical Union organized an International Seminar on Monitoring Geosystems - Perspectives for the 21st century, at University of Delhi during December 6-9, 1991. The contributed papers were modified and updated. The present volume includes 26 contributions dealing with concepts and methods, related to global environmental change.

Remote Sensing plays a key role in monitoring the various manifestations of global climate change. It is used routinely in the assessment and mapping of biodiversity over large areas, in the monitoring of changes to the physical environment, in assessing threats to various components of natural systems, and in the identification of priority areas for conservation. This book presents the fundamentals of remote sensing technology, but rather than containing lengthy explanations of sensor specifications and operation, it concentrates instead on the application of the technology to key environmental systems. Each system forms the basis of a separate chapter, and each is illustrated by real world case studies and examples. Readership The book is intended for advanced undergraduate and graduate students in earth science, environmental science, or physical geography taking a course in environmental remote sensing. It will also be an invaluable reference for environmental scientists and managers who require an overview of the use of remote sensing in monitoring and mapping environmental change at regional and global scales.

The chapters in this book present state-of-the-art geomatics technologies applied in global environmental studies. This text provides the latest research findings and delivers complete references to related publications. This book will motivate the undergraduate and graduate students, researchers and practitioners to better understand the environmental changes with informed solutions. Global Change studies are increasingly considered a vital source of information to understand the Earth Environment, especially in the framework of human-induced, climate change and land use transformation. Satellite Earth Observing systems and geomatics technologies provide a unique tool to monitor and model the changes, respectively. While the range of applications and innovative techniques are always increasing, this book provides a summary of key study cases where satellite data offers critical information to understand the usefulness of the geomatics technologies and global environmental issues. Geomatics technologies provide powerful tools to model and analyze the effects of those global environmental changes towards minimizing their adverse impacts on human health and the environment.

Environmental change is increasingly considered a critical topic for researchers across multiple disciplines, as well as policy makers throughout the world. Mounting evidence shows that environments in every part of the globe are undergoing tremendous human-induced change. Population growth, urbanization and the expansion of the global economy are putting increasing pressure on ecosystems around the planet. To understand the causes and consequences of environmental change, the contributors to this book employ spatial and non-spatial data, diverse theoretical perspectives and cutting edge research tools such as GIS, remote sensing and other relevant technologies. International Perspectives on Global Environmental Change brings together research from around the world to explore the complexities of contemporary, and historical environmental change. As an InTech open source publication current and cutting edge research methodologies and research results are quickly published for the academic policy-making communities. Dimensions of environmental change explored in this volume include: Climate change Historical environmental change Biological responses to environmental change Land use and land cover change Policy and management for environmental change

Land Remote Sensing and Global Environmental Change: The Science of ASTER and MODIS is an edited compendium of contributions dealing with ASTER and MODIS satellite sensors aboard NASA's Terra and Aqua platforms launched as part of the Earth Observing System fleet in 1999 and 2002 respectively. This volume is divided into six sections. The first three sections provide insights into the history, philosophy, and evolution of the EOS, ASTER and MODIS instrument designs and calibration mechanisms, and the data systems components used to manage and provide the science data and derived products. The latter three sections exclusively deal with ASTER and MODIS data products and their applications, and the future of these two classes of remotely sensed observations.

Re-envisioning Remote Sensing Applications: Perspectives from Developing Countries aims at discussing varied applications of remote sensing, with respect to upcoming technologies with diverse themes. Organized into four sections of overlapping areas of research, the book covers chapters with themes related to agriculture, soil and land degradation studies; hydrology, microclimates and climate change impacts; land use/land cover analysis applications; resource analysis and bibliometric studies, culminating with future research agenda. All the topics are supported via case studies and spatial data analysis. Features: Provides the applications of remote sensing in all fields through varied case studies and spatial data analysis Includes soil and land degradation, microclimates, and climate change impacts Covers remote sensing applications in broad areas of agriculture, hydrology, land use/land cover change and resource analysis Discusses usage of GPS-enabled smartphones and digital gadgets used for mapping and spatial analysis Explores future research agenda for applications of remote sensing in post-COVID scenario This book is of interest to researchers and graduate students in environmental sciences, remote sensing, GIS, agricultural scientists and managers, forestry scientists and managers, and water resources scientists and managers.

Environmental transformation is increasingly considered a crucial subject for scientists across various disciplines, as well as policy makers around the globe. Mounting evidence reveals that environments around the globe are undergoing some drastic changes. Increasing population, urbanization and development of the global economy are putting more pressure on ecosystems. To comprehend the roots and consequences of environmental modification, the writers of this book employ spatial and non-spatial data, different theoretical visions, and cutting edge research tools such as GIS, remote sensing technology, etc. Global perspectives on environmental modification bring together research from around the world to investigate the complexities of modern and historical environmental change. Features of environmental modification explored in this book include: climate change, historical environmental change and biological responses to environmental change.
