Mezinárodní obchod s čerstvým ovocem a zeleninou / International trade with fresh fruit and vegetables

Laketić, Aleksandar January 2012 (has links)
The main goal of my Master´s thesis is to evaluate dynamic environment of international trade with fresh fruit and vegetables. In the first part of my thesis I analyzed importance of the production of fresh fruit and vegetables for economies of selected countries. Next I had described the trade flows and patterns. In the second part I made a characterization of payment terms and trade negotiations in the context of international trade with fresh fruit and vegetables. Furthermore I made an analysis of import and export rules and regulations of the EU. Based on this analysis I came to general conclusions on the trade policies of countries and communities. In the last part of my thesis I applied findings from the previous parts on the analysis of two cases. The first analyzed case is the situation of imports of Chinese pomelo to the EU, with regards to maximal residue levels of pesticides. Second analyzed case is the situation of South African citruses imported to the EU, with regards to the problematic of citrus black spots.

Community Risk Factors and Health Inspection Violations in Mississippi Delta Census Tracts

Early, Chrystal S 01 January 2019 (has links)
A concerning public health issue in America is about food deserts urban and rural communities that lack grocery retailers that offer affordable, nutritious, and diverse foods. Empirical evidence has shown significant associations between neighborhood disadvantage/disorder risk factors of high poverty and high percentages of ethnic minority residents with presence/ absence of healthy food retailers in food deserts. The purpose of this quantitative correlational study, framed by the disparities in food safety conceptual model, was to examine if county-level poverty, number of African American residents, number of elderly (i.e., age 65 or older) residents, vehicle ownership, and crime rates were significantly associated with presence/absence of healthy food retail environments in a stratified random sample of 160 Mississippi Delta Region counties. Variables were measured using SPSS 25.0 data set from federal sources. Data were analyzed using binary logistic regression. Findings indicated that the percentage of households below poverty level was significantly associated with absence of healthy food retailers, (Wald X2 = 7.62, p = .006). Logistic regression findings further showed that the county percentage of households with at least one vehicle was significantly associated with the presence of healthy food retailers, (Wald X2= 8.75, p = .003). As a result of this study, residents of the Mississippi Delta Region (MDR) may begin to petition their local, county, and state governments to enhance access to healthy foods, and in turn, such government institutions may develop programs and initiatives that help to make healthy foods affordable.

Bestimmungsgründe von Veränderungen in der Wertschöpfungskette für Obst und Gemüse

Stolper, Oliver 28 May 2015 (has links)
Die Wertschöpfungskette für frisches Obst und Gemüse in Deutschland hat sich in den letzten Jahrzehnten stark gewandelt. Die Konzentration im Einzelhandel, andere Konsumgewohnheiten und verbesserte Logistik haben Beschaffung und Angebot stark verändert. Daneben sind neue Stakeholder aufgetreten, die erfolgreich die Umsetzung ihrer Anliegen einforderten, was zu höheren Anforderungen an Produktsicherheit und Qualität führte. In der Wissenschaft beschäftigte man sich bislang nur wenig mit der Wertschöpfungskette für frisches Obst und Gemüse in Deutschland. Einige Autoren erforschten die Mechanismen, wie britische Supermärkte Gemüse aus Ostafrika importierten. Das Modell der Value Chain Analysis und die Transaktionskostentheorie bilden den theoretischen Rahmen der vorliegenden Arbeit. Erster Schritt war die Identifizierung der relevanten Akteure und ihrer Position in der Kette. Es zeigte sich, daß es keine einheitliche Value Chain gibt, sondern daß die Beschaffung der einzelnen Produkte unter-schiedlich organisiert ist, sowohl von Unternehmen zu Unternehmen, aber auch innerhalb einer Firma für unterschiedliche Produkte. In einem zweiten Schritt wurden sorgfältig ausgewählte Experten aus Produktion, Zwischen- und Einzelhandel zu den Veränderungen in der Value Chain und deren aktueller Ausgestaltung interviewt. Besonderer Wert wurde dabei auf die Ver-träge und Beziehungen zwischen den einzelnen Handelspartnern gelegt, d.h. wie diese zustande kommen, wie sie aufgebaut sind und wie die Kontrolle der Vereinbarungen funktioniert. In einem letzten Schritt wurden die Faktoren herausgearbeitet, die für das aktuelle Aussehen der Value Chain entscheidend sind. Weitere Ergebnisse waren, wie das Governance-System in der Realität funktioniert, wie konsequent Vorgaben und Standards umgesetzt werden und wie die Verbindungen zwischen den einzelnen Partnern gestaltet sind. Dabei kristallisierten sich drei unterschiedliche Einkaufstypen im LEH heraus. / The value chain for fresh fruit and vegetables in Germany has changed considerably through-out the last decades. The convergence in retail, transformed consumer habits and improved logistics have had great impact on procurement and supply. In addition, new stakeholders have emerged, who successfully demand the implementation of their requirements, resulting in a higher demand for product safety and product quality. So far, science has addressed the value chain model on fresh fruit and vegetables in Germany only briefly. In fact, there are only few studies available on the mechanisms of UK supermar-ket imports of vegetables from East Africa. The model of the Value Chain Analysis and the transaction cost theory should hence form the theoretical framework of this study. The first step was the identification of relevant players and their position within the chain. It was found that there is no single value chain present, but that the procurement of the individ-ual products is organized, changing, both from company to company, but also within a com-pany for different products. In a second step, a group of carefully selected experts from production, intermediary trade and retail were asked to comment on the changes and the current structure of the value chain. Special emphasis was placed on the contracts and relationships between the individual trading partners, i.e. how these agreements are made, what do they include and how their compliance is guaranteed. In a last step, the crucial factors were identified that are critical for the current appearance of the Value Chain. Other results included the determination of the true governance system, findings about how consistent the guidelines and standards are implemented and how the connections between the individual partners are designed. As a result, three different procurement types can be de-termined in food retailing.
