Remote Sensing-Based Time Series Models For Malaria Early Warning In The Highlands Of Ethiopia, A. Midekisa, G. Senay, G. M. Henebry, P. Semuniguse, M. C. Wimberly May 2012

Remote Sensing-Based Time Series Models For Malaria Early Warning In The Highlands Of Ethiopia, A. Midekisa, G. Senay, G. M. Henebry, P. Semuniguse, M. C. Wimberly

Natural Resource Management Faculty Publications

Background

Malaria is one of the leading public health problems in most of sub-Saharan Africa, particularly in Ethiopia. Almost all demographic groups are at risk of malaria because of seasonal and unstable transmission of the disease. Therefore, there is a need to develop malaria early-warning systems to enhance public health decision making for control and prevention of malaria epidemics. Data from orbiting earth-observing sensors can monitor environmental risk factors that trigger malaria epidemics. Remotely sensed environmental indicators were used to examine the influences of climatic and environmental variability on temporal patterns of malaria cases in the Amhara region of Ethiopia ...


An Integrated Approach For Developing Adaptation Strategies In Climate Planning: A Case Study Of Vulnerability In Dukes County, Massachusetts, Jonathan Pollak May 2012

An Integrated Approach For Developing Adaptation Strategies In Climate Planning: A Case Study Of Vulnerability In Dukes County, Massachusetts, Jonathan Pollak

Master's Theses

Climate Action Plans (CAP’s) are recent innovations in policy that have been catalyzed by a need to adjust the relationship between human activity and the Earth’s climate system. CAP’s often are composed of methods to mitigate greenhouse gas emissions in addition to adaptation strategies. Research indicates, however, that many plans focus on mitigation strategies while adaptation policies related to predicted changes caused by climate change are often overlooked. This thesis presents an integrative framework for locating areas that are in need of adaptation strategies through a GIS based decision support system that visualizes vulnerability. It is operationalized ...


The Detection Of Forest Structures In The Monongahela National Forest Using Lidar, Dominique Norman Jan 2012

The Detection Of Forest Structures In The Monongahela National Forest Using Lidar, Dominique Norman

Theses, Dissertations and Capstones

The mapping of structural elements of a forest is important for forestry management to provide a baseline for old and new-growth trees while providing height strata for a stand. These activities are important for the overall monitoring process which aids in the understanding of anthropogenic and natural disturbances. Height information recorded for each discrete point is key for the creation of canopy height, canopy surface, and canopy cover models. The aim of this study is to assess if LiDAR can be used to determine forest structures. Small footprint, leaf-off LiDAR data were obtained for the Monongahela National Forest, West Virginia ...


The Environmental And Cultural Effects On The Conquest Of Mexico, Tristan Siegel Jan 2012

The Environmental And Cultural Effects On The Conquest Of Mexico, Tristan Siegel

Senior Projects Spring 2012

In this work I examine the environment and cultural attitudes of Mesoamericans, specifically the Mexica (Atzec), and how these factors played a role in the Conquest of Mexico by Hernan Cortes. I begin by examining Mesoamerican agriculture, lithic technology, and metallurgy. I conclude by examining how these factors played out in the Conquest.


Grts And Graphs: Monitoring Natural Resources In Urban Landscapes, Todd R. Lookingbill, John Paul Schmit, Shawn L. Carter Jan 2012

Grts And Graphs: Monitoring Natural Resources In Urban Landscapes, Todd R. Lookingbill, John Paul Schmit, Shawn L. Carter

Geography and the Environment Faculty Publications

Environmental monitoring programs are an important tool for providing land managers with a scientific basis for management decisions. However, many ecological processes operate on spatial scales that transcend management boundaries (Schonewald-Cox 1988). For example, adjacent lands may influence protected-area resources via edge effects, source-sink dynamics, or invasion processes (Jones et al. 2009). Hydrologic alterations outside management units also may have profound effects on the integrity of resources being managed (Pringle 2000). The impacts of climate change are presenting challenges to resource management at local-to-global scales (Karl et al. 2009). This potential disparity between ecological and political boundaries presents an interesting ...


The Geography Of Greenhouse Gas Emissions From Within Urban Areas Of Asia, Jochen Albrecht, Peter Marcotullio, Andrea Sarzynski, Niels Schulz Jan 2012

The Geography Of Greenhouse Gas Emissions From Within Urban Areas Of Asia, Jochen Albrecht, Peter Marcotullio, Andrea Sarzynski, Niels Schulz

Publications and Research

This paper aims to advance two objectives: (1) identify and explore greenhouse gas emissions from urban areas in Asia at the regional level; and (2) explore covariates of urban greenhouse gas emissions. We use the Emissions Database for Global Atmospheric Research estimates for carbon dioxide, methane, nitrous oxide, and sulfur hexafluoride from 14 source activities for the year 2000, which are allocated on a 1/108 global grid. We extract emissions for 3535 urban extents all with populations over 50,000, accounting for approximately 91% of the region’s urban population. We use regression analysis to associate emissions with urban ...


Streamflow Analysis And A Comparison Of Hydrologic Metrics In Urban Streams, Matthew Lawton Wood Jan 2012

Streamflow Analysis And A Comparison Of Hydrologic Metrics In Urban Streams, Matthew Lawton Wood

Dissertations and Theses

This study investigates the hydrologic effects of urbanization in two Portland, Oregon streams through a comparison of three hydrologic metrics. Hydrologic metrics used in this study are the mean annual runoff ratio (Qa), mean seasonal runoff ratio (Qw and Qd), and the fraction of time that streamflow exceeds the mean streamflow during the year (TQmean). Additionally, the relative change in streamflow in response to storm events was examined for two watersheds. For this investigation urban development is represented by two urbanization metrics: percent impervious and road density. Descriptive and inferential statistics were used to evaluate the relationship between the hydrologic ...
