Background. Grapevine leafroll disease is one of the most widespread viral diseases in vineyards, affecting nearly all grape and wine regions in the world. Infection causes yield losses, ripening delays, and alters fruit chemistry, including lowering soluble solids and increasing titratable acidity. The viruses associated with leafroll disease are(More)
A series of coordinated case studies compares the structure, size, and performance of local food supply chains with those of mainstream supply chains. Interviews and site visits with farms and businesses, supplemented with secondary data, describe how food moves from farms to consumers in 15 food supply chains. Key comparisons between supply chains include(More)
F ood value chains (FVCs) comprise all activities required to bring farm products to consumers, including agricultural production, processing, storage, marketing, distribution, and consumption. FVCs are changing rapidly in developing countries (DCs), because of population and income growth; urbanization; and the expansion, globally and domestically, of(More)
Grapevine leafroll disease threatens the economic sustainability of the grape and wine industry in the United States and around the world. This viral disease reduces yield, delays fruit ripening, and affects wine quality. Although there is new information on the disease spatial-dynamic diffusion, little is known about profit-maximizing control strategies.(More)
— We compare the impacts across a range of criteria of local and regional procurement (LRP) relative to transoceanic shipment of food aid in Burkina Faso and Guatemala. We find that neither instrument dominates the other across all criteria in either country, although LRP commonly performs at least as well as transoceanic shipment with respect to(More)
We measure the links between store attribute perceptions and customer satisfaction, and between customer satisfaction and sales performance, in the food retail sector. Our data set consists of six waves of customer satisfaction and sales information for about 250 stores over the period 19982001 for a publicly held supermarket company. We construct a(More)
We developed and evaluated an empirical model of the U.S. dairy supply chain with a high degree of spatial and product disaggregation to assess the impacts of increasing localization of the northeast region's fluid milk supply on food miles, supply chain costs, greenhouse gas and criteria pollutant emissions, economic activity, and employment. Evaluation(More)
It is the Policy of Cornell University actively to support equality of educational and employment opportunity. No person shall be denied admission to any educational program or activity or be denied employment on the basis of any legally prohibited discrimination committed to the maintenance of affirmative action programs which will assure the continuation(More)
There is increased interest in greater localization of food supply chains but little evidence about the effects of localization on supply chain costs. Assessing these effects is complex in multipleproduct, multi-process supply chains such as the dairy industry. In this study, we develop a spatially-disaggregated transshipment model for the US dairy sector(More)
