Amazonian States Map Threatened Borderlands, David S. Salisbury, A. William Flores De Melo, Jorge Vela Alvarado, Bertha Balbin Ordaya Oct 2012

Amazonian States Map Threatened Borderlands, David S. Salisbury, A. William Flores De Melo, Jorge Vela Alvarado, Bertha Balbin Ordaya

Geography and the Environment Faculty Publications

Recently, the Regional Initiative to Integrate South America has begun promoting a transboundary road that would bisect the forested borderlands and connect the two largest cities in the region, while the state governments seek to promote a direct ecological railroad alternative. Both transportation initiatives promise to alter forests and rivers and transform economies and cultures, but these projects also lack the base geographic information necessary to understand their potential transboundary impacts and benefits.

Perú tiene 67 millones de hectáreas de bosque, que viene a ser más del 53% de la superficie total del país (OIMT, 2010). La extracción maderera es la propulsora principal de la economía dentro de la Amazonía Peruana, generando empleos para comunidades rurales y urbanas (Sears y Pinedo-Vásquez, 2011). Sin embargo, a menudo los empresarios madereros explotan a sus trabajadores a través de un sistema de préstamos (De la Rosa Tincopa, 2009). Alrededor de 1354 comunidades indígenas poseen títulos de propiedad en la región (OIMT, 2010), pero muchas comunidades no tienen los títulos para su territorio que muchas veces se …

Potential Wolverine Habitat Vs. Winter Recreation. Conflict In Colorado!, Paul Quigley Jan 2012

Potential Wolverine Habitat Vs. Winter Recreation. Conflict In Colorado!, Paul Quigley

Geography and the Environment: Graduate Student Capstones

The Global list of endangered species of flora and fauna is growing, with the most highly specialized species often at ‘critically endangered’ status. Managing these populations effectively involves numerous and varied organizations, conflicting motivations, arbitrary anthropogenic boundaries and often most importantly, data compilation and management. We are seeing many more reintroductions of locally extirpated species back into habitats of historical prevalence – and as extreme a method of conservation as this is, there is still a need for more extreme methods. High profile and highly specialized endangered species are often managed in a ‘crisis’ mode, where complex behaviors and interactions …

Transboundary Political Ecology In The Peru-Brazil Borderlands: Mapping Workshops, Geographic Information, And Socio-Environmental Impacts, David S. Salisbury, A. William Flores De Melo, Pedro Tipula Tipula Jan 2012

Transboundary Political Ecology In The Peru-Brazil Borderlands: Mapping Workshops, Geographic Information, And Socio-Environmental Impacts, David S. Salisbury, A. William Flores De Melo, Pedro Tipula Tipula

Geography and the Environment Faculty Publications

Development, resource, and settlement frontiers inspired by national policies and global demand continue to expand into the international boundary lands of Amazonia. National policies promote development and conservation projects on lands already inhabited and managed. Regional governments are increasingly frustrated by the inadequate and outdated geographic information available to solve overlapping claims and improve planning in sensitive border regions. The resulting combination of inappropriate policies, contested resources, and poor geographic information in the borderlands create impacts not only for national, regional, and local landscapes and livelihoods but also foreign relations due to transboundary effects. This article uses a transboundary political …

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 area and growth, …

Participatory Planning For A Promised Land: Citizen-Led, Comprehensive Land Use Planning In New York’S Adirondack Park, Ann Hope Ruzow Holland Jan 2010

Participatory Planning For A Promised Land: Citizen-Led, Comprehensive Land Use Planning In New York’S Adirondack Park, Ann Hope Ruzow Holland

Antioch University Dissertations & Theses

New York’s Adirondack Park is internationally recognized for its biological diversity. Greater in size than Yellowstone, Everglades, Glacier, and Grand Canyon National Park combined, the Adirondacks are the largest protected area within the Northern Appalachian/Acadian Eco-Region and within the contiguous United States. Ecologists, residents of the Park, and others are concerned about rapid land use change occurring within the borders of the Park. Almost half of the six million acres encompassed by the Park boundary is privately-owned, where 80% of land use decisions fall within the jurisdiction of local governments. The comprehensive planning process of one such local government, the …

Finding A "Disappearing" Nontimber Forest Resource: Using Grounded Visualization To Explore Urbanization Impacts On Sweetgrass Basketmaking In Greater Mt. Pleasant, South Carolina, Patrick T. Hurley, Angela C. Halfacre, Norm S. Levine, Marianne K. Burke Nov 2008

Finding A "Disappearing" Nontimber Forest Resource: Using Grounded Visualization To Explore Urbanization Impacts On Sweetgrass Basketmaking In Greater Mt. Pleasant, South Carolina, Patrick T. Hurley, Angela C. Halfacre, Norm S. Levine, Marianne K. Burke

Environment and Sustainability Faculty Publications

Despite growing interest in urbanization and its social and ecological impacts on formerly rural areas, empirical research remains limited. Extant studies largely focus either on issues of social exclusion and enclosure or ecological change. This article uses the case of sweetgrass basketmaking in Mt. Pleasant, South Carolina, to explore the implications of urbanization, including gentrification, for the distribution and accessibility of sweetgrass, an economically important nontimber forest product (NTFP) for historically African American communities, in this rapidly growing area. We explore the usefulness of grounded visualization for research efforts that are examining the existence of "fringe ecologies" associated with NTFP. …

Gis-Based Decision Support For Drained Wetland Resoration In The Eel River Watershed Of N. E. Indiana, Xiangheng Yang Dec 2000

Gis-Based Decision Support For Drained Wetland Resoration In The Eel River Watershed Of N. E. Indiana, Xiangheng Yang

All-Inclusive List of Electronic Theses and Dissertations

The objective of this research is to develop cost-effect and accurate methods to identify optimal restorable drained wetland cropland sites. Landsat Thematic Mapper (TM) data analysis was used to identify the potential cropland candidate sites in the initial step. The result of digital TM data analysis shows that the overall classification accuracy in identifying classes of potential restoration candidate hydric soils is 86.7%. This accuracy shows that the TM data digital analysis is a cost-effective method for identifying poorly drained cropland hydric soils potentially suitable for wetland conversiOn. To support multi-factorial analysis in the final site screening, a Spatial Decision …

Intelligent Visualization And Automated Processing For Large Scale Geographic Information Systems, Yu Jiang Dec 1999

Intelligent Visualization And Automated Processing For Large Scale Geographic Information Systems, Yu Jiang

All-Inclusive List of Electronic Theses and Dissertations

This research focuses on developing a new output system that compacts maps in multiple projections into a single Geographic Information System (GIS) without visual errors, through constructing a discrete GIS database that is managed by a Relational Data Base Management System (RDBMS). Unlike in a traditional large GIS database, the data are "physically discrete but logically continuous." In a new discrete GIS database, every map keeps its individuality without a relationship to any other map, and the relationships among the maps are centrally managed by a RDBMS. A study site was chosen at the boundary of the state of Indiana …
