Extractions: CIESIN Thematic Guides NASA initiated the Landsat Pathfinder data set in 1991, with the intent of reconfiguring selected portions of the global Landsat data archive to optimize use of Landsat data for global change research. The historical archive consists of 21 years of Landsat Multispectral Scanner (MSS) data at a spatial resolution of 80 meters, and 11 years of Landsat Thematic Mapper (TM) data at a spatial resolution of 30 meters. The Landsat Pathfinder Program Definition Phase Report [not yet available] provides a complete description of the Landsat Pathfinder concept and component activities (publication expected late 1994). The Landsat Pathfinder data set currently includes three component efforts. The first is the Humid Tropical Forest Inventory Project , which is associated with developing a complete three-epoch, consistently processed Landsat database for the humid, tropical forests of the Amazon Basin, Central Africa, and Southeast Asia. The three epochs are generally the early- to mid-1970s, mid-1980s, and the early 1990s. For each epoch, a set of Landsat scenes will be selected on the basis of minimal cloud cover and acceptable data quality to provide complete coverage of the humid, tropical forest regions. This data set is intended for evaluation of the rate and extent of tropical deforestation. The second effort is the North American Land Characterization (NALC) Project, which will bring together three epochs of historical Landsat MSS data in a standard configuration for much of the land surface of the North American continent, according to the Environmental Protection Agency research brief (1993)

Sadowski Norm Roller John E. Colwell Environmental Research Institute of Michigan (ERIM) Consortium for International Earth Science Information Network (CIESIN) ABSTRACT Successful implementation of studies addressing the human dimensions of global change will pose major conceptual and methodological challenges for the social sciences. The Landsat Pathfinder Program will offer significant benefits for meeting the challenges facing social scientists studying global change. The benefits include: (1) assisting the development and implementation of a global perspective for research; (2) aiding the coordination of interdisciplinary research; and (3) aiding the longitudinal studies of global environmental change. INTRODUCTION There is increasing awareness that the collective actions of humanity are capable of affecting the Earth system and its processes. Humanity, in turn, is capable of being affected by changes in the Earth system induced by these effects. The nature of humanity's actions at different levels in society (local, national, and international) and in the fabric of society (for example, its social, economic, and political structures and institutions) comprise what are commonly referred to as the human dimensions of global change.

Extractions: Advances Deforestation Mapping By Walter Chomentowski, Bill Salas , and David Skole . Chomentowski and Salas are research scientists and Skole is an assistant professor with the University of New Hampshire Complex Systems Research Center, Institute for the Study of Earth, Oceans, and Space, Morse Hall, Durham, NH 03824-3525, USA. The Landsat Pathfinder project is demonstrating the use of Landsat data for global change research and monitoring the world's forest resources. One of the five Pathfinder projects initiated by the U.S. National Aeronautics and Space Administration (NASA), Landsat Pathfinder is a first step toward establishing a global monitoring system using high-resolution satellite imagery. The imagery will be stored, managed and analyzed with a GIS. Pathfinder is part of NASA's response to the requirements of the U.S. Global Change Research Programthe centerpiece of which is the Earth Observing System (EOS) satellite series. Scheduled to begin operation in 1998, EOS will transmit as much as two terabytes (2,000 gigabytes) of Earth data each day. Pathfinder's mission is to explore the data needs of scientists studying global change and prepare for the massive EOS data stream. Some researchers estimate the global deforestation rate has more than doubled since the early 1980's; others say it has increased by only 50 percent. The Landsat Pathfinder project will help scientists better quantify estimates of land use/land cover change in the world's tropical forests. Above, the project's study area is shown in red. The Amazon/Orinoco river basins, central Africa and southeast Asia contain 75 percent of the world's tropical forest.

Extractions: Deforestation in Amazonia D. L. Skole is an associate professor and W. H. Chomentowski and W. A. Salas are research scientists at the Institute for the Study of Earth, Oceans, and Space, University of New Hampshire, Durham, NH 03824. A. D. Nobre is a scientist at the Instituto Nacional de Pesquisas Amazonas, Manaus, Amazonas, Brazil. Tropical deforestation is an important component of global change; it has a large influence on hydrology, climate, and global biogeochemical cycles (Crutzen and Andreae 1990, Houghton 1991, Houghton and Skole 1990, Salati and Vose 1984, Shukla et al. 1990). The Brazilian Amazon region is the largest intact tropical forest in the world. Brazil has the highest deforestation rate in the world, according to some estimates; deforestation rates may be 1.5 - 2.0 x 10(6) ha/yr (FAO 1993, Myers 1991, Skole and Tucker, 1993). Understanding of tropical deforestation, an important aspect of global change, is inadequate for two reasons: a lack of accurate measurements of its rate, geographic extent, and spatial pattern and a lack of insight into its causes (Skole in press). It seems obvious that tropical deforestation is the consequence of a variety of interrelated social, economic, and environmental factors. Yet, interpretations of how these factors interact to stimulate deforestation vary widely. Some interpretations focus chiefly on population growth, whereas others regard institutions as the main determinant (Allen and Barnes 1985, Browder 1988, Bunker 1984b, Meyer and Turner 1992, Moran et al. this issue, Rudel 1989, Sanderson in press).

Extractions: Land panel Meeting Summary Steven W. Running (email@example.com), Chair, Land Panel T he newly defined Land Panel met at the end of the IWG meeting in Hunt Valley, MD, October 21, 1994. The panel sees its charge as providing a sounding board for EOS Management when opinions are needed on EOS Land Science related issues, and as a vehicle to bring issues from the science community to EOS management. The Land Panel plans to meet during every IWG meeting, and in the interim interact using the firstname.lastname@example.org Internet address. Special meetings may be convened on specific topics requiring critical action. A particular theme of the panel is to improve coordination between sensor team members producing EOS algorithms and IDS team members using these algorithms for EOS science. The following initial issues were discussed: The advantage of keeping separate but interacting ASTER and Landsat Teams, as suggested by the chairs of both, Anne Kahle and Darrel Williams. The Land Panel endorses this suggestion. The opportunity of the land science community to request regional monitoring using the ASTER sensor. Part of the ASTER duty cycle is available for targeted requests. Anyone interested should contact Anne Kahle, JPL.

It's primary goals were to determine how the boreal forest interacts with the atmosphere (via the transfer of gases and energy), how much carbon is stored in the forest ecosystem, how climate change will affect the forest, and how changes in the forest affects weather and climate. The BOREAS Follow-on is a collection of data sets containing additional information from the BOREAS Project. Forest Ecosystem Dynamics - The Forest Ecosystem Dynamics Program (FEDS) is concerned with modeling and monitoring ecosystem processes and patterns in response to natural and anthropogenic effects. The overall objective of the FED project is to link and use models of forest dynamics, soil processes and canopy energetics to understand how ecosystem response to change affects patterns and processes in northern and boreal forests and to assess the implications for global change. Landsat Pathfinder Project - The goal of the Landsat Pathfinder Program is to establish long-term, medium- to high-resolution data sets for particular regional and global applications to global change research.
