Multicriteria decision analysis: Overview and implications for environmental decision making Multicriteria decision analysis: Overview and implications for environmental decision making
Environmental decision making involving multiple stakeholders can benefit from the use of a formal process to structure stakeholder interactions, leading to more successful outcomes than traditional discursive decision processes. There are many tools available to handle complex decision making. Here we illustrate the use of a multicriteria decision analysis (MCDA) outranking tool...

A simulation model of land-use change in the Lake Tahoe Basin of California and Nevada, as used in a decision-support system A simulation model of land-use change in the Lake Tahoe Basin of California and Nevada, as used in a decision-support system
The Tahoe Land-Use Change model is a stochastic, spatially explicit simulation of future land-use change—in particular, development and retirement of individual parcels—in the Lake Tahoe Basin of California and Nevada. The Federal, State, and regional management agencies responsible for the basin are revising and integrating their 20-year plans to meet various goals, including...

Reconciling carbon-cycle concepts, terminology, and methods Reconciling carbon-cycle concepts, terminology, and methods
Recent projections of climatic change have focused a great deal of scientific and public attention on patterns of carbon (C) cycling as well as its controls, particularly the factors that determine whether an ecosystem is a net source or sink of atmospheric carbon dioxide (CO2). Net ecosystem production (NEP), a central concept in C-cycling research, has been used by scientists to...

Integrating Stakeholders and Users into the Geography Discipline's Research Process Integrating Stakeholders and Users into the Geography Discipline's Research Process
Future research priorities of Geography emphasize the discipline's leadership role in the U.S. Geological Survey (USGS) in multidisciplinary and integrated research on human and environmental systems and how these systems are interrelated and respond to change Geography's research priorities also emphasize providing science that is usable to society and creating decision support products

Geodetic observations of post-seismic transients in the context of the earthquake deformation cycle Geodetic observations of post-seismic transients in the context of the earthquake deformation cycle
Satellite geodetic techniques that can measure displacements with millimeter-level accuracy reveal transient signals in the deformation fields produced by both moderate and large earthquakes. These post-seismic signals exhibit characteristic time scales ranging from weeks to decades and distance scales from hundreds of meters to hundreds of kilometers. By considering them in the context...

Land-cover trends in the Mojave basin and range ecoregion Land-cover trends in the Mojave basin and range ecoregion
The U.S. Geological Survey's Land-Cover Trends Project aims to estimate the rates of contemporary land-cover change within the conterminous United States between 1972 and 2000. A random sampling approach was used to select a representative sample of 10-km by 10-km sample blocks and to estimate change within +/- 1 percent at an 85-percent confidence interval. Landsat Multispectral Scanner...

Processed 1938 aerial photography for selected areas of the lower Colorado River, southwestern United States Processed 1938 aerial photography for selected areas of the lower Colorado River, southwestern United States
The U.S. Geological Survey (USGS) initiated a study of the Lower Colorado River to derive temporal-change characteristics from the predam period to the present. In this report, we present summary information on accomplishments under a USGS task for the Department of the Interior's Landscapes in the West project. We discuss our preliminary results in compiling a digital database of...

Colonia development and land use change in Ambos Nogales, United States-Mexican border Colonia development and land use change in Ambos Nogales, United States-Mexican border
This report outlines a planning approach taken by a Federal Government partnership that is meant to promote sustainable development in the future, integrating both sides of the United States-Mexican border. The twin-city area of Nogales, Ariz., and Nogales, Sonora, Mexico, known collectively as Ambos (both) Nogales, has a common borderland history of urban growth presumably based on...

Miocene rapakivi granites in the southern Death Valley region, California, USA Miocene rapakivi granites in the southern Death Valley region, California, USA
Rapakivi granites in the southern Death Valley region, California, include the 12.4-Ma granite of Kingston Peak, the ca. 10.6-Ma Little Chief stock, and the 9.8-Ma Shoshone pluton. All of these granitic rocks are texturally zoned from a porphyritic rim facies, characterized by rapakivi textures and miarolitic cavities, to an equigranular aplite core. These granites crystallized from...

Perceptions of earthquake and tsunami issues in U.S. Pacific Northwest port and harbor communities Perceptions of earthquake and tsunami issues in U.S. Pacific Northwest port and harbor communities
Although there is considerable energy focused on assessing natural hazards associated with earthquakes and tsunamis in the U.S. Pacific Northwest, little has been done to understand societal vulnerability to these hazards. Part of understanding societal vulnerability includes assessing the perceptions and priorities of public sector individuals with traditional emergency management

The no-project alternative analysis: An early product of the Tahoe Decision Support System The no-project alternative analysis: An early product of the Tahoe Decision Support System
We report on the development of a No-project alternative analysis (NPAA) or “business as usual” scenario with respect to a 20-year projection of 21 indicators of environmental and socioeconomic conditions in the Lake Tahoe Basin for the Tahoe Regional Planning Agency (TRPA). Our effort was inspired by earlier work that investigated the tradeoffs between an environmental and an economic...
