Abstract / Description
The study of ancient Maya intensive, intra-site agricultural systems, such as kitchen gardens, has gained new interest in recent years as a valuable way of interpreting numerous aspects of the ancient Maya's daily life (e.g. subsistence and settlement patterns, population growth, diet and nutrition, gender roles). However, while contemporary Maya kitchen gardens can often be easily identified and studied by cultural anthropologists and archaeologists, ancient kitchen gardens are usually much...
Show moreThe study of ancient Maya intensive, intra-site agricultural systems, such as kitchen gardens, has gained new interest in recent years as a valuable way of interpreting numerous aspects of the ancient Maya's daily life (e.g. subsistence and settlement patterns, population growth, diet and nutrition, gender roles). However, while contemporary Maya kitchen gardens can often be easily identified and studied by cultural anthropologists and archaeologists, ancient kitchen gardens are usually much harder to identify by traditional archaeological techniques because of their lack of architectural structures and other identifying features. To compensate for this limitation, various forms of chemical testing (primarily phosphate analysis) are being used to positively identify kitchen gardens and other specific anthropogenically modified spaces that are invisible to standard archaeological techniques. The archaeological community trusts these methods to be a reliable way of testing soils in archaeological sites for specific agricultural features, even though there has been little research conducted to conclusively prove this assertion. In response to this lack of research, this thesis investigates the viability of phosphate analysis and other chemical tests through a comprehensive literary review of previous and current research and an analysis of the data presented within it. While soil phosphate analysis has been used in past and current research to identify general agricultural features with great success, the chemical signatures produced from this method only give vague information about the soil and what was done to it, making soil Phosphate analysis unreliable to definitively discern specific agricultural areas, such as kitchen gardens, from general agricultural areas.

Show moreIn recent years, the interests of introducing autonomous robots by growers into agriculture fields are rejuvenated due to the ever-increasing labor cost and the recent declining numbers of seasonal workers. The utilization of customized, autonomous agricultural robots has a profound impact on future orchard operations by providing low cost, meticulous inspection. Different sensors have been proven proficient in agrarian navigation including the likes of GPS, inertial, magnetic, rotary encoding, time of flight as well as vision. To compensate for anticipated disturbances, variances and constraints contingent to the outdoor semi-structured environment, a differential style drive vehicle will be implemented as an easily controllable system to conduct tasks such as imaging and sampling.In order to verify the motion control of a robot, custom-designed for strawberry fields, the task is separated into multiple phases to manage the over-bed and cross-bed operation needs. In particular, during the cross-bed segment an elevated strawberry bed will provide distance references utilized in a logic filter and tuned PID algorithm for safe and efficient travel. Due to the significant sources of uncertainty such as wheel slip and the vehicle model, nonlinear robust controllers are designed for the cross-bed motion, purely relying on vision feedback. A simple image filter algorithm was developed for strawberry row detection, in which pixels corresponding to the bed center will be tracked while the vehicle is in controlled motion. This incorporated derivation and formulation of a bounded uncertainty parameter that will be employed in the nonlinear control. Simulation of the entire system was subsequently completed to ensure the control capability before successful validation in multiple commercial farms. It is anticipated that with the developed algorithms the authentication of fully autonomous robotic systems functioning in agricultural crops will provide heightened efficiency of needed costly services; scouting, disease detection, collection, and distribution.

Show morePrior to orange juice concentrate, Florida citrus was already an industrialized agricultural sector. This thesis explores the early-20th-century Florida citrus industry and demonstrates that contemporary farming practices were influential in advancing how citrus was produced, processed, worked, marketed, and regulated in early-20th-century Florida. Restarted after devastating freezes in 1894-1895, resolute Florida growers rebuilt their groves into marvels of large-scale citrus fruit production. Continuing a legacy in experimental crossbreeding, improved varieties of citrus were developed to lengthen the season and markets. Advocated by nurserymen and university educators, biological innovation helped the citrus thrive in the 1910s and 1920s from adverse weather effects, pests, and diseases. Scientists were agents of modernization whose research influenced its industrialization. With the inclusion of machines in the processing of citrus, technological innovation materialized significantly in Florida's packinghouses by the 1930s. These changes affected the lives of agricultural workers and small growers. Whether by prejudice or by resisting collective efforts, big growers gained power and influence in the industry, Their power concentrated into the Florida Citrus Codes and Florida Citrus Commission in 1935, which effectively allowed large-scale growers to direct the industry's development into the rest of the 20th century. In all, this reexamination into Florida citrus exemplifies the remaking of this industry into a modern agricultural system as well as the gradualism of southern agricultural modernization in early-20th-century America.

Show moreThis research study investigated the level of bone collagen preservation of rat femora from Liang Bua cave on the island of Flores, Indonesia, as well as conducted carbon and nitrogen stable isotopic analyses on well preserved samples. Although Flores is located in a hot intermediate tropical zone and the burial environment of the bone samples within the cave is considered less than optimal for collagen preservation, significant preservation of the bone collagen was found. Collagen yields, C:N ratio and carbon and nitrogen concentrations were investigated. However, this research study argues that carbon and nitrogen concentrations are an appropriate means to determine preservation on its own. According to the carbon and nitrogen concentration data 32 samples were considered well preserved. Carbon and nitrogen stable isotopic analyses were conducted on the 32 preserved samples. According to the carbon data a significant shift in the [delta]13C values from a C3 signature to a C4 signature occurred prior to 2,750 years ago. This shift is indicative of the introduction of a non-endemic C4 plant, which is believed to be either foxtail millet or sugarcane. Since this shift occurs abruptly it indicates that the introduction of agriculture to Flores occurred at one time and has continued to present day.

Show morePurpose of this study is to holistically analyze existing linkages between Aruba's tourism industry, restaurants and local farmers, by examining strategies that constrain the development of linkages between these stakeholders. Previous research indicated that tourism development is often accompanied with increased demand for imported food, which results in foreign exchange leakages, inflation and competition with local production. This phenomenon is very common in the Caribbean, where Aruba, with its heavy reliance on imported goods and services, is no exception to this occurrence. To comprehend potential problems associated with linking both sectors, these in-depth case study addresses three fundamental questions: a) what is the structure of supply and demand of food for the tourism industry of Aruba?, and b) what factors constrain the development of linkages between international tourism and Aruba's local agriculture? Using an exploratory and stochastic methodological approach, data will be obtained from structured surveys from three different stakeholders in the food supply chain of Aruba. Anticipated findings illustrate that the existing linkage between the tourism industry and agriculture in Aruba is still weak, yet the food consumption and preferences by tourists can contribute in enhancing an eco-gastronomic tourism supply chain.
