Suburbanization As A Post-Industrial Essentiality: Revisiting Sweden's Miljonprogrammet, Colin Wood
Suburbanization As A Post-Industrial Essentiality: Revisiting Sweden's Miljonprogrammet, Colin Wood
Swarthmore Undergraduate History Journal
Definitively speaking, suburbanization does not equate to post-industrialism in the same limelight as would urbanization and industrialism. However, anomalous cases, such as the one being discussed in this paper, tangentially interlink on a socioeconomic basis. In 1965, Sweden began construction of the Miljonprogrammet (Million Programme), where over the next ten years, over one million domiciles were built in a suburban setting leading to a mass diaspora of ‘slum living’ Swedish industrial workers. The nation’s renowned welfare state, built on a collaborative system between public and private sectors as well as federal and municipal actors, overlooked housing in its social …

This study presents a preliminary proof of concept evaluating the spatial implications of banning campfires at or above 11,000 feet—used here as a proxy for treeline—in twelve U.S. Forest Service-managed Wilderness areas. Using 30-meter resolution Digital Elevation Models from the USGS National Map and Earth Explorer, a raster-based analysis in ArcGIS Pro identified and quantified acreage above 11,000 feet. Across the twelve Wilderness areas, 268,601 acres were found to lie above treeline, representing an …
Evaluating Spatiotemporal Vegetation Index Variation To Detect Salt Marsh Dieback On The Georgia Coast, Emmanuella Bosompemaa Obeng
Evaluating Spatiotemporal Vegetation Index Variation To Detect Salt Marsh Dieback On The Georgia Coast, Emmanuella Bosompemaa Obeng
College of Graduate Studies: Theses & Dissertations
Salt marshes, essential for coastal protection and carbon sequestration, are increasingly vulnerable to dieback events, threatening ecosystem resilience and vital services. Detecting these shifts early is essential for timely intervention. However, few studies have applied Early Warning Signals (EWS) to coastal marsh systems. Most EWS research has focused on lakes, forests, or climate tipping points, with limited application to salt marsh dieback in the southeastern U.S. Site-specific, long-term spatial analyses are also lacking, as prior work often examines short time frames or single disturbance events. This study investigates the spatiotemporal patterns of salt marsh dieback on the Georgia coast from …
