Assessing Cover Crop Adoption Factors In The Rio Grande Valley Through A Social-Ecological Perspective, Mackenzie Feldman
Assessing Cover Crop Adoption Factors In The Rio Grande Valley Through A Social-Ecological Perspective, Mackenzie Feldman
Theses and Dissertations
Reducing agriculture’s negative environmental impacts is crucial for mitigating climate change (White, 2021). Cover crops– non-cash crops grown to benefit subsequent cash crops– can slow erosion, improve soil health, enhance water availability, control pests, and increase biodiversity. Despite these benefits, adoption rates remain low, prompting the USDA and other organizations to fund research on increasing their use. Most studies focus on the Midwest and Northeast, and emphasize individual factors over the relationship between structural factors and individual factors that impact farmers’ decisions to adopt cover crops. This USDA-funded study begins to fill this gap by exploring social-ecological factors and how …

A Hellenistic-Period Farmhouse At Aderet In The Judean Shephelah, Jon Seligman, Ora Yogev
A Hellenistic-Period Farmhouse At Aderet In The Judean Shephelah, Jon Seligman, Ora Yogev
'Atiqot
The excavation at Aderet, located south of Ha-Ella Valley, revealed a farmhouse with an olive-oil press, which operated under the administrative control of Idumea during the Hellenistic period. Based on the numismatic evidence and the pottery assemblage, the Aderet farmhouse was dated to the second half of the third century BCE, possibly extending into the beginning of the second century BCE. The firmly dated regional ceramic assemblage of the third century BCE expands our knowledge of Hellenistic rural society. The chronology of the Aderet farmhouse is considered in light of Yogev’s suggestion to identify a late Iron Age occupation phase …
The Impact Of The Nitrates Directive On The Portuguese Agricultural Sector, Ben Mayes
The Impact Of The Nitrates Directive On The Portuguese Agricultural Sector, Ben Mayes
Portugal: Sustainability and Environmental Justice
The European Union’s 1991 Nitrates Directive was designed to mitigate agricultural nitrogen pollution to ground and surface waters, thereby alleviating its damaging effects to natural environments and human health. This study confirmed that its purpose and goals were justified by the positive linear relationship that exists between levels of agricultural fertilizer application and nitrogen ecosystem surplus. However, this policy has had several second-hand impacts on the Portuguese agricultural sector, such as imposing infrastructure implementation costs and forcing methodology changes. These impacts were examined in the context of the Esposende-Vila do Conde action program, which is within a Nitrate Vulnerable Zone …

Street-Side Sovereignty: Informal Produce Vendors, Subsistence, And Chosen Interdependencies, Owen W. Lee
Street-Side Sovereignty: Informal Produce Vendors, Subsistence, And Chosen Interdependencies, Owen W. Lee
Samoa: Social and Environmental Change in Oceania
This paper summarizes findings from a 2024 survey and interview conducted with street-side produce vendors in Western Samoa. Produce vendors are understood within the informal economy in Samoa and the phenomenon is contextualized through a history of Pacific food regimes. In opposition to the contemporary corporate food regime, produce vendors operate through small-scale, informal operations which demonstrate variability and individual agency. Through the theoretical framework of food sovereignty, informal produce vendors’ survey and interview responses are analyzed to position vendors’ work within both the global and the Pacific food sovereignty movements, with special attention to land access and localized food …

Ephemera As A Versatile Primary Resource: A Case Study Of The Nancy Tucker Postcard Collection, Dylan J. Mcdonald, Jennifer Olguin, Monika Glowacka-Musial
Ephemera As A Versatile Primary Resource: A Case Study Of The Nancy Tucker Postcard Collection, Dylan J. Mcdonald, Jennifer Olguin, Monika Glowacka-Musial
Journal of Western Archives
Ephemera are rich primary sources too often overlooked within archival materials and at collecting institutions. This case study argues that archivists and librarians should recognize ephemera, specifically postcards, as powerful historical documents worthy of scholarly investigation. By analyzing a sample set of digitized postcards held at the New Mexico State University Library, we show how scholars can use postcards to develop evidence-based arguments. Through the images, printed texts, and hand-written inscriptions found on these early 20th century postcards, we demonstrate how researchers can examine the pro-development messages found in southern New Mexico postcards.
