The Fragmentation Of Helcar: A Paratethyan Model For Rhûn, Núrnen And The Dead Marshes, Federico Manzoni

Journal of Tolkien Research

This work proposes a conjectural paleogeographic model linking the Sea of Rhûn, Núrnen and the Dead Marshes to the former Sea of Helcar. Beginning from Christopher Tolkien's suggestion that Rhûn may represent Helcar ``vastly shrunken,'' the study combines textual evidence, the Ambarkanta, Fonstad's cartographic reconstructions, and terrestrial analogues drawn from the evolution of the Paratethys, the Messinian Salinity Crisis and other endorheic basins. Helcar is interpreted not merely as an isolated body of deep water but as the centre of a broader hydrological province subsequently partitioned by relief change, sedimentary infilling, basin isolation and drainage reorganization. Within this model, Rhûn …

Evolution Of Economic Geography’S Focus On Resource Studies: Historical Trajectory, Research Progress, And Emerging Trends, Yanxiang Fan, Canfei He

Bulletin of Chinese Academy of Sciences (Chinese Version)

Amid the intertwined contexts of global climate change, the reshaping of the geopolitical landscape, and China’s economic transformation, complex issues in the resource sector have increasingly come to the fore, highlighting the urgent need for systematic research from the perspective of economic geography. This study constructs an interactive analysis framework of core–extended dimensions to systematically review the developments and trends in resource research from an economic geography perspective. This study establishes a two-layer theoretical analysis framework of core and extended dimensions. The core dimension includes four aspects: resource elements in regional economic development, resource flows in global trade networks, resource …

Historical Redlining, Walkability, And Green Gentrification In Baltimore, Usa, Rafael B. De Andrade, Ella Baynes, Vanessa Belt, Joseph Colasacco, Camden Speilman

The Geographical Bulletin

Historical redlining created persistent patterns of racial segregation and spatial inequality in American cities. However, urban initiatives aimed at increasing green spaces in these neighborhoods increasingly trigger gentrification that can displace original residents. In this study, we examine the spatial intersection of 1930s-era Home Owners' Loan Corporation (HOLC) redlining boundaries, current property values, and multimodal park accessibility in Baltimore, Maryland. Using geographic data from 245 properties and 13 major parks, we developed an accessibility framework incorporating walking, public transit, and automobile travel modes to estimate accessibility to green spaces across neighborhoods with different redlining histories. Our spatial analysis reveals that …

Data-Driven Risk Mapping For Safer Roads: Unincorporated Dekalb County, Georgia, Getachew B. Demisse, Stacy C. Grear, Araya D. Araya, Shimelis Gebru, Solomon Negash, Leo Ladefian, Carlo Frate

The Geographical Bulletin

This study presents a decade-long spatiotemporal analysis of more than 206,000 traffic accidents recorded between 2015 and 2024 in unincorporated DeKalb County, Georgia. The primary goal of the study is to identify critical patterns of roadway risk and inform data‑driven safety interventions. Using crash records from the Georgia Department of Transportation (GDOT) AASHTOWare Safety platform and standardized crash‑rate calculations, the analysis revealed strong temporal regularities, including elevated crash frequencies during afternoon peak hours, Fridays, and seasonal transition periods such as October. Spatial analyses further demonstrate that crashes are highly concentrated along a limited subset of corridors, consistent with High Injury …

Diversity Of Forest Vegetation In The Quarry Landscapes Of Central Polissia, Ukraine (Eastern Europe), Ivan Khomiak, Oleksandr Harbar, Ruslana Vlasenko, Tamara Andriichuk, Oleksandr Lavryk

The Geographical Bulletin

The features of territorial differentiation of vegetation in quarry landscapes are crucial for addressing theoretical issues in landscape science and applied problems of restoration ecology. This study aims to establish the phytocenotic diversity of forest communities. The forest vegetation of the quarry landscapes of Central Polissia includes 7 classes, 9 orders, 15 unions, 24 associations, and 2 groups of undetermined rank. Based on phytocenotic diversity, the quarries of Zhytomyr Polissia fall into three distinct zones: northern, central, and southern. The northern zone necessarily includes groupings of the Vaccinio-Piceetea class and excludes Salicetea purpurea. The central zone mainly features derived forests …

Low-Income, Minority-Serving Public Schools In Southern California Have Disproportionately High Surface Temperatures, Joaquin Murillo, Gabriella R. Dauber, Joshua B. Fisher, Gregory R. Goldsmith

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Extensive evidence demonstrates that people from minority backgrounds often face unequal exposure to extreme heat and have less access to green space that can provide cooling relief. What is less clear is whether these inequities extend to students on school playgrounds, where high temperatures can affect physical health, social and emotional well-being, and learning. We paired high resolution, satellite remote sensing surface temperature data for all 615 of the public schools in Orange County, California (serving ca. 450,000 students) with data on neighborhood household income, race/ethnicity of school enrollment, distance from the coast, and Normalized Difference Vegetation Index as a …

Lgbtq+ People On The Camino De Santiago, Xose Santos, . Wisulanbou

International Journal of Religious Tourism and Pilgrimage

In the many published works on the Camino de Santiago, LGBTQ+ people have never been considered as an subject of study. The widespread idea that the Camino is for everyone serves to invisibilise this group of people. The problems and accusations we have had to face in our fieldwork are proof of how uncomfortable it is for some persons to talk about gender, sexuality and non-heteronormative identities on the Camino. Regardless of the variety of motivations for pilgrimage to Santiago, religion continues to have a very strong presence on this itinerary which generates tensions with sexualities, especially those that are …

Hajj Pilgrimage And Spatial Behaviour In Sacred Space, Zuhriddin Juraev, Young-Jin Ahn, Ji-Yeong Gu

International Journal of Religious Tourism and Pilgrimage

This study examines the behavioural and spatial dynamics of the Hajj pilgrimage through the conceptual lens of behavioural geography, focusing on how sacred space, ritual choreography, and communal experiences shape religious engagement. Centred on the Kaaba and surrounding pilgrimage sites, this study explores how ritual practices such as Tawaf, Sa’i, and standing at Arafat construct immersive and affective experiences for pilgrims. Drawing on an interpretive analysis of visual and textual sources, the study argues that sacred space operates not only as a physical setting but also as a symbolic framework that mediates spiritual transformation and social cohesion. It also highlights …

From Disaster To Resilience: Developing Smart Settlements In The Himalayas, Keshav Bhattarai, Ambika P. Adhikari

Himalayan Research Papers Archive

Nepal’s catastrophic 26 August 2026 Bhote Koshi–Trishuli flood should be understood not only as a humanitarian tragedy but also as a potentially major turning point in updating national settlement and reconstruction policy. Engineers and scientists have described the floods as a glacier–bedrock collapse that triggered an ice-rock avalanche and debris flow. As per the live updates on September 7, 2026, the total death toll was 1,355, and 4,996 people were missing (The Hindu, 2026). Indian and Nepali rescuers worked urgently to locate and rescue people buried under hydropower tunnels, buildings, mud, and landslide debris.

From Himalayan Catastrophe To National Resilience: Lessons From The 2026 Bhote Koshi And Trishuli River Floods In Nepal, Keshav Bhattarai, Ambika P. Adhikari

Himalayan Research Papers Archive

On the morning of 26 August 2026, the mountains above Nepal’s northern frontier delivered a disaster of almost unimaginable speed and scale. A massive mass of ice, rock, and sediment detached in the high Himalayan terrain near the Nepal–Tibet border, descended roughly 1,200 metres, interacted with the Lhende Khola system, and generated a debris-rich flood that surged through the Bhote Koshi and Trishuli river corridors, destroying settlements, markets, roads, bridges, hydropower facilities, and an international border crossing and transforming them into fields of mud, boulders, and wreckage within minutes (ICIMOD, 2026b; Reuters, 2026a). Satellite analysis indicates that a substantial section …

Post-Fire Erosion And Debris Flows In The Western Pacific Northwest, United States: Recent Science And Opportunities, Sara A. Wall, Kevan Moffett, Annette Patton, Ben Leshchinsky, Andrew C. Wilcox, Maryn Sanders, Heejun Chang, Josh Roering

Geography Faculty Publications and Presentations

Most research into post-fire geomorphology has been conducted in regions with frequent fire, such as in dry Mediterranean and temperate climates and less has been conducted in wet forests where wildfire is now expanding with climate change. Because climate, soils, topography, vegetation, management legacies and fire history influence post-fire geomorphic processes, research into post-fire erosion and debris flow hazards across a broader set of climatologies is needed. The western Pacific Northwest (wPNW) of the United States is susceptible to multiple types of post-fire debris flows (i.e. shallow landslide-initiated and runoff-generated) that can be initiated by longer-duration lower-intensity rainfall compared to …

Modeling Bald Eagle Habitat Suitability In The Del Rio Springs Ecosystem Using Lidar And Spatial Analysis, Noah Morales, Hank Vincent, Ronny Schroeder

Student Works

This study expands upon prior research that utilized NDVI-based hotspot analysis from UAS and satellite imagery (Morales et al. 2026) to identify potential bald eagle nesting and foraging areas. While NDVI effectively captures vegetation density, it does not distinguish between vegetation types or landscape structural characteristics necessary for nesting. To address this limitation, this research integrates LiDAR-derived canopy height, terrain slope, and proximity to stream networks to develop a more refined habitat suitability model within the Del Rio Springs ecosystem.

Airborne LiDAR data were used to generate Digital Surface Models (DSM) and Digital Elevation Models (DEM), which were employed to …

Gis Methods To Distinguish Between Land Changes From Smallholder Agriculture And Mining In A Time Series For A Tropical Protected Area Forest, Pacifique Mubamba Madibi, Jean-Paul Kibambe Lubamba, Aiyin Zhang, Robert Gilmore Pontius

Geography

Tropical protected areas face pressures from smallholder agriculture and illegal mining, yet many monitoring approaches reduce these dynamics to net forest loss, obscuring whether change is alternating or persistent. In the Okapi Wildlife Reserve, Democratic Republic of the Congo, where the zoning plan allows only nonperennial crops in agriculture zones and forbids mining throughout the reserve, we analyzed annual Joint Research Centre–Tropical Moist Forest maps from 2000 to 2024 at 30 m spatial resolution. We applied Trajectory Analysis and DynamicPATCH across three study zones: agriculture, mining, and hunting–conservation. Trajectory Analysis classifies each pixel’s twenty-five-year non-forest time series into categories such …
