AbstractCultivar dispersal is related to food choice by the scale of the event: food choice occurs at an individual level, while dispersal occurs at a societal level. Dispersal is investigated by using data from the FAO, specifically the FAOSTAT tool and the GAEZ database, and literature review. A number of methodologies are tested in order to determine the best method for investigating dispersal; methodologies include visal comparison, normalization and statistical analysis of production and consumption values, measures of crop suitability, and investigation of botanical origin. Quantitative analysis is found to be satisfying, while qualitative analyses are found to require more data and investigation. Cultivars are found to be either dispersed globally or localized, with few cultivars in between.
