A number of initiatives have been designed to address food insecurity problems in the U.S., particularly promoting increased consumption of vegetables. However, if the demand for vegetables increases, little is known regarding the impacts of increased demand on the structure of vegetable supply chain. A related relevant question is: if the current supply cannot meet the increase in demand, what are the optimal locations and seasons to expand vegetable production? To address these questions, we develop a transshipment model of the U.S. cabbage sector to assess the impact of closing the gap between current and recommended vegetable intake in the Northeastern region on supply chain structure and costs. We find that the current supply can only meet 40% of increased demand in the Northeastern U.S. In addition, our model suggests that expanding cabbage production to close the intake gap of cabbage consumption leads to de-localization of the supply chain.
