In the past 100 years pet, zoo/aquarium, and research animals have gained unprecedented legal protection from unnecessary human harm via the creation of strict animal cruelty laws. Due to the work of moral philosophers and compassionate lawyers/judges animal cruelty laws have been improved to provide harsher punishments for violations, had their scopes widened to include more animals and had their language changed to better match our evolving conception of animals as independent living entities rather than as merely things for human use. However, while the group of pet, zoo/aquarium, and research animals has enjoyed more consideration by the US legal system, another group of animals has inexplicably been ignored. The farm animals that humans raise for use as food are exempted from nearly every state and federal animal cruelty law for no justifiable reason. In this paper I will argue that our best moral and legal theories concede that we should take animal suffering seriously, and that no relevant difference exists between the group of animals protected by animal cruelty laws and farm animals. Given the lack of a relevant distinction between these two groups I will conclude that current animal cruelty laws should be amended to include farm animals.

The Phoenix area had no sizable Mexican presence before the U.S. took over the territory. Some assumed that the region was founded completely by whites from the outset. Whites and Mexicans actually held nearly equal populations throughout the first two decades of settlement. Though they did not hold equal status, their cohabitation was largely characterized by mutual interdependence and respect. Transforming the Salt River Valley's desert terrain into a regional agricultural hub depended on the Sonorans' preindustrial skills. As the town modernized, a new class of resident sought large scale projects to integrate Phoenix into the U.S. economy. Two pivotal projects achieved this. First, railroad spur lines made Phoenix accessible for migrants, as well as allowing farmers to supply commercial markets profitably. Second, the massive Roosevelt Dam secured a stable water supply for valley farmers. While these projects provided the foundation for development, it was cotton that brought commercial success. Throughout World War I, valley cotton growers capitalized on the booming cotton market by expanding their average acreage from 400 acres in 1912 to 130,000 acres in 1920. This rapid escalation to meet wartime demands depended upon a massive seasonal labor force from Mexico. While this boom brought prosperity to valley farmers, it solidified the Mexican's role in the Salt River Valley as little more than a laborer. Valley cotton growers impressively managed all labor issues through a well-organized collective association. Over-recruitment and wage setting kept workers from collective bargaining for better wages. The cotton growers' hegemony crashed along with cotton prices in 1921. Though the industry recovered fairly quickly, the cotton growers faced a new challenge in the rising national clamor to restrict Mexican immigration to the U.S. Though growers fought restrictions in Congressional hearings throughout the decade, the economic crash of 1929 finally ended widespread Mexican immigration. By the time of the crash, most Mexicans who remained lived in the agricultural peripheries or scattered urban barrios.

Description
Adaptation and transformation have emerged as a key themes for human-environment research, especially in the context of rapid social-ecological changes. The 2008 global financial crisis constitutes a major driver of change with social-ecological ramifications that have yet to be fully explored. Using Greece, the poster child of the euro-crisis as a case-study, this dissertation examines how adaptive capacity is mobilized and even enhanced in times of crisis, paying particular attention to the role played by natural capital. To do so, I focus on the back-to-land trend whereby urbanites seek to engage in food production post-crisis (2008-onwards). In-depth qualitative analysis of back-to-landers’ motivations, experiences, and challenges is integrated with quantitative data about household demographics, incomes and assets, and land management characteristics. The dissertation is organized in three main result papers (chapters). The first seeks to understand why people turn to the land in times of crisis, and the role played by agency. The second analyzes the various assets that people mobilize in order to go back to the land, paying particular attention to the different mobilities necessary for their livelihood transformation. The third examines environmental safety nets in terms of material and non-material benefits that ecosystems provide to people. This research contributes to a wider social-ecological scholarship that seeks to understand how people adapt and transform when confronted with crises, focusing on how land and associated ecosystem services contribute to the resilience of these households, and the role played by agency in this process.

Description
Nitrate contamination to groundwater and surface water is a serious problem in areas with high agricultural production due to over application of fertilizers. There is a need for alternative technologies to reduce nutrient runoff without compromising yield. Carbon nanoparticles have adsorptive properties and have shown to improve germination and yield of a variety of crops. Graphite nanoparticles (CNP) were studied under a variety of different fertilizer conditions to grow lettuce for the three seasons of summer, fall, and winter. The aim of this thesis was to quantify the effect of CNPs on nitrate leaching and lettuce growth. This was accomplished by measuring the lettuce leaf yield, formulating a nutrient balance using the leachate, plant tissue, and soil data, and changing the hydraulic conductivity of the soil to assess the effect on nutrient mobility. summer and fall experiments used Arizona soil with different amounts of nitrogen, phosphorus, and potassium (NPK) fertilizer being applied to the soil with and without CNPs. The winter experiments used three different soil blends of Arizona soil, Arizona soil blended with 30% sand, and Arizona soil blended with 70% sand with a constant fertilizer treatment of 30% NPK with and without CNPs. The results showed that the 70% NPK with CNP treatment was best at reducing the amount of nitrate leached while having little to no compromise in yield. The winter experiments showed that the effectiveness of CNPs in reducing nitrate leaching and enhancing yield, improved with the higher the hydraulic conductivity of the soil.

Description
Payments for ecosystem services (PES) are transactions between landholders and the beneficiaries of the services their land provides. PES schemes are growing worldwide with annual transactions over ten billion dollars (Salzman et al., 2018). Much can be learned from looking at oldest and best funded PES schemes on working agricultural land. Initiated in 1985, the USDA’s Conservation Reserve Program (CRP) is the oldest private conservation PES program in the United States. CRP incentivizes farmers to put their land into conservation through an annual payment. In Iowa, CRP has been a source of extra income and a way for farmers to buffer the fluctuating costs of cash crops, such as corn and soy. The dominance of agriculture in Iowa poses many challenges for water quality. A potential solution to the problem, implemented through CRP, is the use of conservation practices to mitigate the negative effects of agricultural run-off.
This dissertation considers three aspects of the problem:
1. the relationship between changes in land cover due to CRP enrollment and changes in water quality, controlling for a range of factors known to have an effect on the filtering role of different land covers;
2. the inter-annual variability in water quality measures and enrollment in different CRP conservation practices to examine the cost-effectiveness of specific conservation practices in mitigating lake sedimentation and eutrophication;
3. discrete choice models to identify what characteristics drive the enrollment by farmers into specific conservation practices.
Results indicate that land cover and CRP have different impacts on different indicators of lake water quality. In addition, conservation practices that were cost-effective for one water quality variable tended to be cost-effective for the other water quality variables. Farmers are making decisions to enroll in CRP based on the opportunity cost of the land. Therefore, it is necessary to alter financial incentives to promote productive land being putting into CRP through continuous sign-up. The United States Department of Agriculture (USDA) needs a more effective way to calculate the payment level for practices in order to be competitive with the predicted value of major crops.

Description
Small-scale, peasant farmers are some of the most vulnerable people to the effects of climate change. They rely on a stable climate to support their natural ways of farming, which typically depends on consistent rainfall, temperate weather, and predictable season cycles. The perceptions of how successful coffee production is during shifting climatic disruptions is of key importance, if mitigation or adaptation efforts are to be successfully implemented. By using ethnographic methods with members of a coffee cooperative in Mexico, called Cafe Justo, I found that peasant farmers are very perceptive of the climatic changes and recognize forthcoming challenges as a result of changes in weather and precipitation levels. Rain-fed agriculture remains particularly vulnerable to coffee market demands, as coffee production for the majority of the cooperative members is the primary source of income. Through interpretive analysis of in-depth interview data collected from 19 coffee-famers in Chiapas, Mexico, I identified factors associated with perceptions of changing climate and weather conditions. Social identities, general perceptions of climate change, and impacts on livelihoods were investigated through the speaking-with model, as it was presented by Nagar and Geiger in 2007. These findings have rich implications for co-learning between the small-scale, coffee farmers and the scientific community so that mitigation and adaptation strategies are discussed. The findings also merit further investigation into future migration changes due to mass exoduses of climate refugees who are no longer able to successfully cultivate and harvest the lands to serve their needs and those of their community.

Beginning in 2011, California’s most recent drought has brought four years of some of the warmest and driest seasons on record. Mendota, California in the San Joaquin Valley is a microcosm of the struggles many agriculture communities face when water resources are scarce. Known as the “cantaloupe capital of the world,” agriculture represents over half of Mendota’s economy, making unemployment one of the many challenges they face. However, community members are working to move forward and preserve the place they call home.
Medota has a population of about eleven thousand people with over 96 percent of them being Hispanic. The stories of elected officials, field workers, farmers, police, school leaders and local business owners give testament to a mounting fear for future water allocation. But their voices also give way to a shared belief—the community’s resilience will persevere through California’s drought. Mendota is presented through a multi-media piece that uses photos, videos and descriptive articles to showcase both their hardship and hope.

According to the United States Department of Agriculture, "food insecure homes" are households that are at times unable to acquire enough food to met the needs of their members. During the year 2010, this designation applied to roughly 14.5% of American households. In Arizona, the situation is even direr, with nearly 1 in 5 children falling into the range of food insecurity. These alarming statistics appear even graver in the light of the staggering amount of food that is wasted in America. In an attempt to combat both the problems of food insecurity and food waste, organizations have begun to focus their energy on "rescuing and repurposing food." In other words, these organization take prepared and perishable food from one location where it would go to waste, and redistribute it to places that it will be consumed, such as soup kitchens and shelters. The purpose of this thesis is to fully explore the successful workings of Waste Not, Inc. in Phoenix, AZ, and City Harvest in New York City, NY, and then make necessary critiques and draw implications for future food rescue programs.

This thesis details our experience assisting BASE Equity Partners, a private equity firm based in New York City, on three prospective agricultural dealership deals over the course of this past academic year. The firm is currently structured as a Fundless Sponsor. This distinct structural trait is common for a type of private equity firm known among practitioners as pledge funds. This creates an interesting element for our experience as there is very limited academic research on these types of firms, which, since the Great Recession, have become popular players in middle-market private equity deals. We, first, provide some historical context on pledge funds and identify their primary differences with traditional private equity. The remainder of the paper documents our experience working on the agricultural dealership deals. We have organized this portion after the manner in which we received assignments. We go into detail on the specific projects with which we were tasked, our interactions with the partners and the major takeaways we had from this learning experience. This thesis paper will enrich the academic knowledge regarding pledge funds—and private equity generally—by documenting a real experience of what it is like performing analyst-level tasks at a real firm. Additionally, we were privy to information that is highly confidential, and though we have protected the confidentiality of the companies through pseudonyms and redaction of confidential material, all of the financial data shown, models provided and qualitative discussion is real.

Description
A new class of entrepreneurs is emerging in China, who are using a business model approach to solve societal problems. A small but growing niche of these so called "social entrepreneurs" is attempting to address long standing problems in the agricultural sector stemming from the three agricultural issues of farmers, agriculture and rural areas. In order to understand what social entrepreneurship means in the Chinese context, the motivations behind it, and the opportunities and problems related specifically to agricultural sector, interviews were conducted with social entrepreneurs, research institutes, and social fostering organizations in multiple tier-one cities in mainland China. Results show that the concept of social enterprise is comprehended in a very different way in the Chinese context relative to the general usage of the term in the literature. Social enterprises in the agricultural sector are divided into categories of Community Supported Agriculture-based organic farms, farmers' markets, food educators and city farmers. This is a growing group of entrepreneurs who could be better supported on the basis of resources and protection by the government, law and policy, universities, and a united producer and consumer front.
