Remote sensing of global croplands for food security: Way forward Remote sensing of global croplands for food security: Way forward
This book opens a new pathway for global mapping that is focused on a specific land use theme, such as irrigated or rain-fed croplands and classes within these themes. Since croplands use most of the water consumed by humans, specific knowledge of irrigated and rain-fed croplands will be critical for precise estimates of water use. At present and in the coming decades, irrigated and rain...

Uncertainty and sensitivity issues in process-based models of carbon and nitrogen cycles in terrestrial ecosystems Uncertainty and sensitivity issues in process-based models of carbon and nitrogen cycles in terrestrial ecosystems
Many process-based models of carbon (C) and nitrogen (N) cycles have been developed for northern forest ecosystems. These models are widely used to evaluate the long-term decisions in forest management dealing with effects like particulate pollution, productivity and climate change. Regarding climate change, one of the key questions that have sensitive political implications is whether...

Elevation Derivatives for Mojave Desert Tortoise Habitat Elevation Derivatives for Mojave Desert Tortoise Habitat
This report describes the methods used to derive various elevation-derivative grids that were inputted to the Mojave Desert Tortoise Habitat model (L. Gass and others, unpub. data). These grids, which capture information on surface roughness and topographic characteristics, are a subset of the environmental datasets evaluated for the tortoise habitat model. This habitat model is of major

Proceedings of a USGS Workshop on Facing Tomorrow's Challenges Along the U.S.-Mexico Border - Monitoring, Modeling, and Forecasting Change Within the Arizona-Sonora Transboundary Watersheds Proceedings of a USGS Workshop on Facing Tomorrow's Challenges Along the U.S.-Mexico Border - Monitoring, Modeling, and Forecasting Change Within the Arizona-Sonora Transboundary Watersheds
INTRODUCTION TO THE WORKSHOP PROCEEDINGS Competition for water resources, habitats, and urban areas in the Borderlands has become an international concern. In the United States, Department of Interior Bureaus, Native American Tribes, and other State and Federal partners rely on the U.S. Geological Survey (USGS) to provide unbiased science and leadership in the Borderlands region...

A New Method for Mapping Population Distribution A New Method for Mapping Population Distribution
Human population counts are collected and commonly displayed uniformly across areas, such as U.S. Census Bureau block-groups and tracts. The limitation inherent in this type of representation is the assumption that people are evenly distributed across each areal unit, when in actuality many areas such as parks, open spaces, and industrial zones are uninhabited. The U.S. Geological Survey...

Mapping Land Use/Land Cover in the Ambos Nogales Study Area Mapping Land Use/Land Cover in the Ambos Nogales Study Area
The Ambos Nogales watershed, which surrounds the twin cities of Nogales, Arizona, United States and Nogales, Sonora, Mexico, has a history of problems related to flooding. This paper describes the process of creating a high-resolution, binational land-cover dataset to be used in modeling the Ambos Nogales watershed. The Automated Geospatial Watershed Assessment tool will be used to model...

Current and future vulnerability of Sarasota County Florida to hurricane storm surge & sea level rise Current and future vulnerability of Sarasota County Florida to hurricane storm surge & sea level rise
Coastal communities in portions of the United States axe vulnerable to storm-surge inundation from hurricanes and this vulnerability will likely increase, given predicted rises in sea level from climate change and growing coastal development. In this paper, we provide an overview of research to determine current and future societal vulnerability to hurricane storm-surge inundation and to...
