Tending To The Tapestry: An Ecofeminist Interpretation Of Women Farmer-Artists' Stories, Aubrey Pongluelert

Graduate Student Theses, Dissertations, & Professional Papers

There is a disconnect in Western academia, between classroom conversations concerning the impact of environmental degradation on rural communities, and engagement with those communities whom we are discussing. Those working in environmental studies are confronted with the question of how to effectively communicate the concerns addressed by the field in ways which are accessible to, and engage broader audiences. Creative languages such as the visual arts, storytelling, and music are invaluable tools in this task because they offer accessible and culturally relevant means of conveying ideas, perspectives, and experiences. This project examines the ways in which these creative languages contribute …


Intercropping For Water Conservation: Environmental And Economic Implications Of A Sustainable Farming Practice In California's Central Valley, Sophie Baker Jan 2020

Intercropping For Water Conservation: Environmental And Economic Implications Of A Sustainable Farming Practice In California's Central Valley, Sophie Baker

Scripps Senior Theses

California’s agricultural sector is the biggest water consumer in the state and faces intense pressure to reduce its overall water usage. Industrialized monoculture systems dominate the industry and often disregard long-term environmental and economic externalities for short-term profit maximization. To maintain longstanding food security and economic stability as well as protect the state’s water supply, it is critical that these systems transition to more sustainable and resilient production mechanisms. As an alternative to monoculture, intercropping affords greater potential to conserve water, protect soil quality, and increase crop yields, among other metrics of sustainability. However, there has been much controversy over …

The New Veggie Tale: Increasing Access To Sustainably-Grown Food In The U.S., Vanessa Ryan

Student Theses 2015-Present

Since the mid-twentieth century and the green revolution, industrialized agriculture has required fertilizer, pesticides, excess water and added energy that typically comes from fossil fuels, all of which contribute to climate change while threatening human and environmental health. The goals of this thesis are to illustrate the well-documented environmental degradation caused by various industrial farming techniques; to suggest alternative, sustainable farming practices that preserve and promote the vitality of soil and other natural resources; to examine the unequal power of large agribusiness corporations to influence food production and distribution policies; to assess the current federal policies in place that have …


Using Micrometeorology To Gauge Agriculture's Potential To Sequester Soil Carbon, Debra Blumberg O'Dell May 2019

Using Micrometeorology To Gauge Agriculture's Potential To Sequester Soil Carbon, Debra Blumberg O'Dell

Doctoral Dissertations

In addition to reducing carbon dioxide (CO2) emissions from fossil fuel combustion, removing atmospheric CO2 may be critical to limit global warming to less than two degrees Celsius above pre-industrial levels recommended by leading experts. Since cropland occupies 11% of the earth’s land and is intensively managed, cropland agriculture provides one approach for removing CO2 from the atmosphere to mitigate climate change. However, current assessments indicate agriculture is a net emitter of CO2 and other greenhouse gases, and it is unclear how soil management can effect carbon sequestration.In this work micrometeorological methods are used to …

Scholarship and Professional Work - LAS

Campus agriculture projects are increasingly being recognized as spaces impactful to student engagement and learning through curricular and co-curricular programming; however, most campus farm activities are limited to agriculture or sustainability programs and/or co-curricular student clubs. Thus, campus farms are largely underutilized in the undergraduate curriculum, marking a need to explore the efficacy and impact of engaging a diverse array of disciplinary courses in the rich social, environmental, and civic context of local sustainable agriculture. The Farm Hub program presented here incentivizes instructors to refocus a portion of existing course content around the topic of local, sustainable agriculture, and reduces …


Climate Change, Agriculture, And Adaptations: Policy Recommendations For Conservation Agriculture, Sydney Abraham, Mel Dollison Jan 2019

Climate Change, Agriculture, And Adaptations: Policy Recommendations For Conservation Agriculture, Sydney Abraham, Mel Dollison

Climate and Society

This paper examines the intersection of climate change and agriculture with a focus on possibilities for sustainable agriculture in a warmer world. The authors consider the impacts (both positive and detrimental) of climate change on food production systems before engaging with a variety of adaptive strategies including crop diversification, genetically modified organisms (GMOs), and conservation agriculture (CA). These strategies are then applied within the context of sub-Saharan agricultural policy. Ultimately, the authors suggest that policymakers should support rural agriculture by prioritizing conservation agriculture as a critical piece of both mitigation and adaptation policy.

School of Natural Resources: Faculty Publications

Background: Agriculture contributes a third of Rwanda’s GDP and is the main source of income for rural households, with 80% of the total population involved in crop and/or livestock production. The Government of Rwanda established the Muvumba rice project in 2011 amidst a policy shift towards rice as a national staple crop. However, the indiscriminate use of pesticides by local, low-income rice growers has raised concerns about potential human, animal and ecosystem health impacts as pesticide distribution and application are not strictly regulated. Although pesticide use can directly influence farmer health and ecosystems, little is known about small-scale farmers’ pesticide …


Oberlin's Experimental Hazelnut Orchard: Exploring Woody Agriculture's Potential For Climate Change Mitigation And Food System Resilience, Naomi Fireman Jan 2019

Oberlin's Experimental Hazelnut Orchard: Exploring Woody Agriculture's Potential For Climate Change Mitigation And Food System Resilience, Naomi Fireman

Honors Papers

Mitigating and adapting to climate change and transitioning to more sustainable agricultural methods to feed a growing human population are fundamental challenges today. Woody agriculture holds potential for addressing both through food production and carbon sequestration. To help assess this potential, in 2011, Oberlin College planted an experimental orchard made up of 70 hybrid hazelnut trees treated with three levels of fertilization. I asked the questions: How does annual allocation of carbon to different tissues change over time as hybrid hazels mature? How much carbon can this system store, where is it stored, and how does this change over time? …


Mitigating Gaseous Nitrogen And Carbon Losses From Northeastern Agricultural Soils Via Alternative Soil Management Practices, Kyle Michael Dittmer Jan 2019

Mitigating Gaseous Nitrogen And Carbon Losses From Northeastern Agricultural Soils Via Alternative Soil Management Practices, Kyle Michael Dittmer

Graduate College Dissertations and Theses

Traditional agricultural practices often result in gaseous losses of nitrous oxide (N2O), ammonia (NH3), and carbon dioxide (CO2), representing a net loss of nutrients from agricultural soils, which negatively impacts crop yield and requires farmers to increase nutrient inputs. By adopting best management practices (BMPs; i.e., no-tillage, cover crops, sub-surface manure application, and proper manure application timing), there is great potential to reduce these losses. Because N2O and CO2 are also greenhouse gases (GHGs), climate change mitigation via BMP adoption and emissions reductions would be an important co-benefit. However, adopting a no-tillage and cover cropping system has had setbacks within …

The ‘Botanical Triad’: The Presence Of Insectary Plants Enhances Natural Enemy Abundance On Trap Crop Plants In An Organic Cabbage Agro-Ecosystem, Binita Shrestha, Deborah L. Finke, Jaime C. Piñero

Stockbridge Faculty Publication Series

Habitat manipulation through the incorporation of non-crop plants such as trap crops (to lure pests away from the cash crop) and insectary plants (to provide resources for natural enemies) into agro-ecosystems is an ecological approach to pest management. In a field-scale study, we quantified the effects of integrating the use of trap crops with insectary plants as a novel method to control pest herbivores in an organic cabbage agro-ecosystem. We hypothesized that pests would be concentrated in the trap crop habitat and suppressed by insectary-subsidized natural enemies in situ. We documented arthropod abundance (both adults and immature stages) associated with …


Context Is Everything: An Investigation Of Spanish River Carbonatite And Its Effects On Soil-Plant-Microorganism Systems, James Mc Jones Jan 2019

Context Is Everything: An Investigation Of Spanish River Carbonatite And Its Effects On Soil-Plant-Microorganism Systems, James Mc Jones

Theses and Dissertations (Comprehensive)

With growing concerns about agricultural sustainability and food security, the use of rock fertilizers and agrominerals is receiving renewed interest. A wide variety of geological resources have been proposed as crop nutrient sources, with silicate rocks the predominant focus. Carbonatite rocks are known to weather more readily than silicate rocks; yet, they have received relatively little attention as it is thought their high Ca and Mg contents hinder effective nutrient release. However, there is strong evidence that the nutrients within carbonatite rocks are easily accessible to plants, and that these rocks have noticable effects on crop plant growth. Here I …


Relationship Between Habitat And Barn Owl Prey Delivery Rate And Composition In A Napa Valley Vineyard Agroecosystem, Dane A. R. St. George Jan 2019

Relationship Between Habitat And Barn Owl Prey Delivery Rate And Composition In A Napa Valley Vineyard Agroecosystem, Dane A. R. St. George

Cal Poly Humboldt theses and projects

The provision of habitat for natural enemies of agricultural pests is common in integrated pest management approaches globally but has rarely been examined for vertebrate predators controlling vertebrate pests. To mitigate the economic and environmental costs of treating for rodent pests, winegrape producers in Napa Valley, California, have installed nest boxes to attract barn owls (Tyto alba) to their properties, but their effectiveness to control rodent pests in vineyards has not been thoroughly tested. A rigorous estimate of the number of rodents barn owls remove from the landscape is a necessary first step, and this study aimed to …


Design And Development Of A Front Mounted On-The-Go Soil Strength Profile Sensor, Ari̇f Behi̇ç Teki̇n, Harun Yalçin Jan 2019

Design And Development Of A Front Mounted On-The-Go Soil Strength Profile Sensor, Ari̇f Behi̇ç Teki̇n, Harun Yalçin

Turkish Journal of Agriculture and Forestry

Soil compaction is a great problem since it affects crop growth and yield. The causes of soil compaction are the management practices in agricultural production. A common practice is to implement subsoiling at a few centimeters below the hardpan. Management practices, field traffic, and variations of the soil?s physical and chemical properties throughout the field cause variations in the soil compaction degree and depth. Subsoiling at certain depths can cause excessive energy consumption at a high cost. Therefore, agricultural tillage equipment could be improved by varying the tillage depth. Soil strength is the main indicator that depends on several soil …

Biological control, a globally-important ecosystem service, can provide long-term and broad-scale suppression of invasive pests, weeds and pathogens in natural, urban and agricultural environments. Following (few) historic cases that led to sizeable environmental up-sets, the discipline of arthropod biological control has—over the past decades—evolved and matured. Now, by deliberately taking into account the ecological risks associated with the planned introduction of insect natural enemies, immense environmental and societal benefits can be gained. In this study, we document and analyze a successful case of biological control against the cassava mealybug, Phenacoccus manihoti (Hemiptera: Pseudococcidae) which invaded Southeast Asia in 2008, where …

Increasing Carbon Footprint Of Grain Crop Production In The Us Western Corn Belt, Chaoqun Lu, Zhen Yu, Hanqin Tian, David A. Hennessy, Hongli Feng, Mahdi Al-Kaisi, Yuyu Zhou, Tom Sauer, Raymond Arritt

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Global agriculture is challenged to increase soil carbon sequestration and reduce greenhouse gas emissions while providing products for an increasing population. Growing crop production could be achieved through higher yield per hectare (i.e. intensive farming) or more hectares (extensive farming),which however, have different ecological and environmental consequences.Multiple lines of evidence indicate that expanding cropland for additional production may lead to loss of vegetation and soil carbon, and threaten the survival of wildlife. New concerns about the impacts of extensive farming have been raised for the US Corn Belt, one of the world’s most productive regions, as cropland has rapidly expanded …
