Economic and human development in the Moroccan Sahara

Between the challenges of urbanization and the constraints of the desert center

This article deals with the forms of economic and human development in Guelmim-Smara, Laayoune-Boujdour, Dakhla-Oued Ed-Dahab, and research in the region from an area of displacement to an area of population polarization, and the vacuum that the countryside has become known in contrast to the increase in the population in urban areas, and the accompanying development Natural constraints and spatial imbalances.

High-Throughput Phenotyping Of Rice Grains Subjected To High Nighttime Temperature Stress, Shannon Shareice Cunningham

Student Theses and Dissertations

Rice grain size is affected by high nighttime temperature stress (HNT). Although studied in small subsets, the Rice Diversity Panel 1 has not been extensively studied to determine HNT effects on grain size. Accessions have been identified as tolerant and sensitive to HNT under greenhouse conditions (Dhatt et al., 2020). A high throughput phenotyping (HTPP) method and a PlantCV2 workflow were implemented in this work to determine grain dimensions. Seed area was found to be a good indicator of HNT tolerance with a coefficient of variation being 15%. Among tolerant accessions, seed area increased by an average of 1.57 mm2 …

Contesting Erasure: The Museu Da Maré And The Right To The City In Rio De Janeiro, Brazil, Pamela Katia Sertzen

Dissertations - ALL

Rapid growth in cities of the Global South has precipitated urban inequalities, particularly the urban and social exclusion of low-income city residents. Right to the city scholars have investigated claims to urban space but have not fully considered the role of museums and the politics of memory as central to the debate about contesting erasure in low-income areas. While Latin American memory studies scholars have analyzed traumatic events such as dictatorships and civil wars in the region and memorialization practices that evolved post-trauma, they have not yet taken into account contested favela memories and their role in the right to …

Observations Of Post-Wildfire Landcover Trends In Boreal Alaska Using A Suite Of Remote Sensing Approaches, Eric John Deutsch

Theses - ALL

Wildfires are a common occurrence in the boreal ecosystems of the Pacific Northwest. Studies suggest that anthropogenic climate change has fostered more frequent and higher severity fires in recent decades in these forests, which may result in substantial changes in vegetation structure and ecosystem functioning. However, large-scale studies examining the linkages between changing boreal wildfire regimes and vegetation structure have historically been limited in spatial scope due to the broad area and inaccessibility of many boreal regions, including the Alaskan interior. The development and advancement of satellite remote sensing instruments and geospatial analysis techniques provide researchers with unmatched abilities to …

Rgb Indices And Canopy Height Modelling For Mapping Tidal Marsh Biomass From A Small Unmanned Aerial System, Grayson R. Morgan, Cuizhen Wang, James T. Morris

Faculty Publications

Coastal tidal marshes are essential ecosystems for both economic and ecological reasons. They necessitate regular monitoring as the effects of climate change begin to be manifested in changes to marsh vegetation healthiness. Small unmanned aerial systems (sUAS) build upon previously established remote sensing techniques to monitor a variety of vegetation health metrics, including biomass, with improved flexibility and affordability of data acquisition. The goal of this study was to establish the use of RGB-based vegetation indices for mapping and monitoring tidal marsh vegetation (i.e., Spartina alterniflora) biomass. Flights over tidal marsh study sites were conducted using a multi-spectral camera on …

Cellphilming And Building Solidarity With Queer Youth To Speak Back To Historical Erasures In New Brunswick Social Studies Classrooms, Casey Burkholder

The Councilor: A National Journal of the Social Studies

New Brunswick, Canada’s K-12 Social Studies curricula erases the myriad histories and experiences of the province’s LGBTQ+ communities. Building on these erasures, this study analyzes how six queer, trans, and non-binary young people (aged 14-17) created cellphilms (cellphone + mobile film production) in response to these absences. In the study, I ask: How might engaging in media and art production with young people—and screening and exhibiting these productions in online and community spaces—work to counter dominant forms of apathy and denial, and support youth to claim a stake in creating solidarities, belonging, and community-making? What is required for youth-produced media …

No. 01: South-South Migration, Food Insecurity And The Covid-19 Pandemic, Jonathan Crush, Diana Thomaz, Sujata Ramachandran

Migration and Food Security (MiFOOD) Network

The implementation of global migration governance processes such as the 2030 Sustainable Development Agenda and the Global Compact for Migration has been stalled by the COVID-19 crisis as flows of and opportunities for international migrants shrink through the containment strategies adopted by most governments in response to the pandemic. Migrants have been disproportionately affected by COVID-19 and the policies taken in response to the pandemic, with higher risk of exposure to the virus, greater likelihood of working in sectors that have experienced major economic downturn, lower rates of access to social support mechanisms and health care, and increased vulnerability to …

No. 02: Food Remittances, Migration And Rural-Urban Linkages In Kenya, Elizabeth Opiyo Onyango, Jonathan Crush, Samuel Owuor

Migration and Food Security (MiFOOD) Network

Rural-urban migrants in Sub-Saharan Africa do not generally cut their links with rural homes and much has been written about the character, types and implications of connections between rural areas and rapidly growing cities. The persistence of circular migration and the perpetuation of rural-urban connectivity is a distinctive feature of Kenyan urbanization. Informal non-market food remitting from rural to urban areas has received little attention in comparison with cash remitting from city to countryside. This paper presents new evidence from a household survey in Nairobi on the extent, frequency and nature of informal food remitting from rural areas to migrants …

Changes In The Flood Plains And Water Quality Along The Himalayan Rivers After The Chamoli Disaster Of 7 February 2021, Sansar Raj Meena, Kushanav Bhuyan, Akshansa Chauhan, Ramesh P. Singh

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The Himalayan regions are vulnerable to all kinds of natural hazards. On 7 February 2021, a deadly disaster occurred near the Tapovan, in Uttarakhand, Himalayas. During the event, large volume of debris along with broken glacial fragments flooded the Rishi Ganga River and washed away the nearby hydropower plants (Rishi Ganga and Tapovan), which was revealed from detailed analysis of multi spectral and bi-temporal satellite data. We present the impact of the Chamoli disaster on the flood plains and water quality of Himalayan rivers, Rishi Ganga near Tapovan, Alaknanda near Srinagar and Ganga near Haridwar and Bijnor. We used four …

Active Rock Glaciers Of The Contiguous United States: Geographic Information System Inventory And Spatial Distribution Patterns, Gunnar Johnson, Heejun Chang, Andrew G. Fountain

Geography Faculty Publications and Presentations

In this study we present the Portland State University Active Rock Glacier Inventory (n=10 332) for the contiguous United States, derived from the manual classification of remote sensing imagery (Johnson, 2020; https://doi.org/10.1594/PANGAEA.918585). Individually, these active rock glaciers are found across widely disparate montane environments, but their overall distribution unambiguously favors relatively high, arid mountain ranges with sparse vegetation. While at least one active rock glacier is identified in each of the 11 westernmost states, nearly 88 % are found in just five states: Colorado (n=3889), Montana (n=1813), Idaho (n=1689), Wyoming ( …

Management Of The Berea College Forest: Changes Over The Past Century, Hinzee Smith, Forrest Stevens Phd

Undergraduate Research Events

• The Berea College Forest was started in 1898 when Silas C. Mason purchased the first tract of forest land.

• The land that was acquired was not ideal forest land, often having soil erosion and other problems due to previous overgrazing or over-farming, poor logging habits, and general neglect.

• Mason’s main goals for the forest were to provide timber, educational opportunities, recreation, and water production for the college and surrounding areas.

Hydrologictrends Inthe Sacred Valley Of The Incas, Samuel C. Kessler, C. Andrew Day Phd

Undergraduate Research Events

Through 2018-2019, the University of Louisville International Service Learning Program sent teams of students & faculty to the Vilcanota-Urubamba basin of Peru (the Incan “Sacred Valley”), to assist with water resource management and mapping flow losses from decaying irrigation infrastructure. Additional issues with water availability were noted. Farmers in the region had reported insufficient rains towards the end of the wet season. Some also reported shifting climate with more rain than usual during planting season at colder times preventing germination in some cases, as well as traditional freeze-drying practices.

In 2019 the government of Peru (Autoridad Nacional del Agua) was …

Pyrophytic Tree Classification In Berea Forest Using Unmanned Aerial Systems, Jacob Foushee, Andrea Gaughan Phd, Forrest Stevens Phd, Hinzee Smith

Undergraduate Research Events

Pyrophyte - Tree species adapted to endure fire. Despite its defenses,

-Passive Pyrophyte - Resist the effects of fire.

-Active Pyrophyte - Requires fire to spread, germinate, and regrow

Despite its defenses, a pyrophyte can be overwhelmed and destroyed by fire. After decades of total fire suppression policies along with rising average temperatures as a result of climate change, forest fires have grown in intensity, frequency, and coverage.

With the assistance of Unmanned Aerial Systems (UAS), foresters can survey the distribution of pyrophytic trees and develop sustainable approaches to forest management that restore the natural ecosystem and reduce the threat …

How Did Homelessness Change During The Great Recession And Recovery?, Jenny Schuetz, Matthew Ring

Policy Briefs and Reports

Job losses from the COVID-19 pandemic have exacerbated housing insecurity among low-income renters over the past year. Federal, state, and local policymakers have created temporary measures to help reduce displacement among people who have lost their jobs, but there is considerable uncertainty about what will happen when these temporary measures end. To gain insight into how homelessness changes over macroeconomic cycles, we examine changes in homelessness rates from 2007 to 2020. Our analysis focuses on four metro areas that were particularly hard-hit by the foreclosure crisis: Las Vegas, Los Angeles, Phoenix, and Riverside. Overall homelessness rates declined in all metros …
