Soil Succession: Short And Long-Term Impacts Of Grazing On Soil Properties In A Tropical Montane Cloud Forest, June Curtis

Independent Study Project (ISP) Collection

Cattle ranching is the leading cause of deforestation in South America, causing long-lasting alterations to the continent's landscape and ecology. Tropical montane cloud forests (TMCFs) are a rare ecosystem particularly vulnerable to the effects of land conversion to pasture, a process which has implications ranging from biodiversity loss to soil degradation. Grazing is known to significantly alter soils' physical structure through processes of compaction and erosion as well as significant additions of organic matter. Silvopasture, or the integration of pasture and forest, has emerged as an alternative to traditional grazing practices with the hope of mitigating environmental and soil degradation. …

Portugal To New Mexico: Investigating The Applicability Of Syntropic Agriculture To A Semi-Arid Continental Climate, Arielle Nathan

Independent Study Project (ISP) Collection

Conventional industrial agriculture has numerous detrimental effects on the environment including high carbon emissions, pollution and overconsumption of water, soil degradation, and reduction of biodiversity (FAO, 2018). Large-scale alternatives are needed to combat these negative consequences and provide climate solutions. Syntropic Agriculture is a promising farming alternative especially in arid systems subject to degraded soils and desertification. New Mexico is a semi-arid continental climate in a prolonged period of drought and predicted to experience worsening agricultural conditions due to desertification, wildfire intensification, and exacerbated water scarcity. In an area with similar agricultural challenges, a project in Mértola, Portugal (Terra Sintrópica) …

The Truth Behind Avocado Expansion In The Algarve: A Synthesis Of Public, Environmental Associations, And Government Perspectives And Response, Mandy Ausman

Independent Study Project (ISP) Collection

Avocado expansion has exponentially increased in the Algarve region of southern Portugal in recent years. The surge in expansion has provoked contention and discrepancy in the media regarding how and if avocado production can persist in the water-scarce region due to worsening drought conditions related to climate change coupled with the fruit’s significant water footprint. This paper aims to synthesize the arguments and response of the public, environmental associations, and government agencies to the expansion of avocado production in the water- scarce region of the Algarve, highlight the region’s current challenges of avocado expansion and water management regulation, and analyze …


Assessing The Performance Of Agricultural Systems In The Inland And Coastal Regions Of Northern Portugal Using Indicators: Establishing The Foundation Towards Better Agricultural Practices, Genevieve Gehlken Oct 2023

Assessing The Performance Of Agricultural Systems In The Inland And Coastal Regions Of Northern Portugal Using Indicators: Establishing The Foundation Towards Better Agricultural Practices, Genevieve Gehlken

Independent Study Project (ISP) Collection

This study conducts a comprehensive evaluation of agricultural systems in the distinct coastal and inland regions of Northern Portugal. Employing key indicators, including soil erosion, nitrogen surplus, irrigation practices, Agricultural Gross Domestic Product (GDP), and crop yield, the analysis reveals statistically significant disparities and unique challenges in each region. The coastal areas, marked by higher agricultural GDP, exhibit distinct economic dependencies on agriculture, while the inland regions face challenges related to water scarcity, soil erosion, and rural isolation. The looming threat of climate change adds complexity to these dynamics, further highlighting the need for region-specific, sustainable agricultural practices. In the …


Unveiling The Impact: Mexico's Decree On Genetically Modified Corn And Its Ramifications On Food Security, Lauren Mcshea Oct 2023

Unveiling The Impact: Mexico's Decree On Genetically Modified Corn And Its Ramifications On Food Security, Lauren Mcshea

Independent Study Project (ISP) Collection

This research delves into the repercussions of Mexico's presidential decree in late 2020, which imposed a ban on the human consumption of genetically modified (GM) corn by January 2024. In a trade dispute under the United States-Mexico-Canada Agreement (USMCA), the decree has sparked tensions between Mexico and the United States, particularly concerning the disruption of GM corn exports. Beyond trade dynamics, the study aims to address the broader impact on Mexico's food security landscape, exploring the intricate connections between the ban and various factors, including agricultural practices, economic implications, and shifts in the corn market dynamics. This research seeks to …

Por tres semanas, investigué la soberanía alimentaria y sus implicaciones en relaciones entre personas, pueblos, el gobierno, la sociedad, y el mundo no humano en la Reserva Pambiliño, el pueblo de Mashpi, y la Reserva de Biósfera del Chocó Andino de Pichincha en Ecuador. Trabajé manualmente en la finca; entrevisté a trabajadores de la Reserva Pambiliño y miembros de la Fundación Imaymana; y realicé la observación participante en una variedad de actividades en Mashpi y el Chocó Andino. Allí, redes de ayuda mutua conectan comunidades, fincas, y reservas que trabajan en la agroforestería, la conservación, la restauración de bosques primarios, …


Neoliberalismo Y La Mar: Los Efectos Del Sistema Neoliberal Y La Pesca Artesanal De Caleta Portales, Isaac Bronfine Apr 2023

Neoliberalismo Y La Mar: Los Efectos Del Sistema Neoliberal Y La Pesca Artesanal De Caleta Portales, Isaac Bronfine

Independent Study Project (ISP) Collection

This study is meant to explore the fundamental conflict between the neoliberal system implemented in Chilean society and the artisanal fishing sector, represented by Caleta Diego Portales in Valparaíso, Chile. The struggle of the artisanal fishing sector has been made more salient in the minds of the general Chilean public due to the estallido social or “social explosion” in 2019 which lead to a process of drafting a new constitution, and the recent corruption scandals regarding government officials and fishing law reforms.

Beginning with how neoliberal theory gained traction in intellectual spaces around the world, this study then examines how …


Dairy & Development: An Investigation Into The Economic And Sociopolitical Dynamics Of Yak Cheesemaking In Nepal, Audrey Peiker Apr 2023

Dairy & Development: An Investigation Into The Economic And Sociopolitical Dynamics Of Yak Cheesemaking In Nepal, Audrey Peiker

Independent Study Project (ISP) Collection

Cheesemaking in Nepal is full of love, passion, and creativity. What began as a Swiss development project in the 1950s has now grown into a full-fledged industry, providing jobs, creative outlets, and cultural expression for many. Nepal’s Dairy Development Corporation owns several factories throughout the country, setting the tone for the industry by establishing the standard price for milk and process for cheesemaking. From there, privately held factories innovate and compete, bringing new products to the market and increasing wages, but also struggle with consistency and reliability. Now, Nepal’s cheesemaking market is at a turning point—much of the herding population …


Ecological Living In Nepali Food Systems: A Synthesis Of Circular Nutrient And Knowledge Flows In The Kathmandu Valley, Kaitlyn Feely Apr 2023

Ecological Living In Nepali Food Systems: A Synthesis Of Circular Nutrient And Knowledge Flows In The Kathmandu Valley, Kaitlyn Feely

Independent Study Project (ISP) Collection

Researching food-systems in Nepal can feel like drinking from a fire hydrant. Sixty-six percent of the population is directly involved in agriculture and a diverse set of ecocultural understandings influence the practice across the country’s landscapes, ranging from the Himalayas to urban centers to southern plains. In the Kathmandu Valley and peripheral hills where I conducted my research, seemingly any spare land was under cultivation, enabled by fertile ground, optimal climate, and market potential. But despite the prevalence of farming in daily life throughout the country, Nepal’s food system is not domestically self-sufficient. A complex web of imports and exports …
