Abstract
Localized food production and sourcing is drawing increasing attention due to economic, environmental and health considerations. Yet significant challenges exist, such as how to effectively and efficiently map the localized supply and demand. In order to address this issue, we developed a framework that incorporates the population, dietary, and geographical information to map the potential foodsheds. The focus in this study is to minimize the total geographic distribution among the foodsheds. We also developed innovative protocols and metrics to analyze the foodshed localization of geographic areas. Data from Iowa are utilized to analyze and validate the optimization model. This study has the potential to be adapted to other regions.
