A number of concepts and tools have been developed to measure and classify crop diversity. Here we synthesize these concepts and measures to enable the development of a framework within which each can be considered and analyzed at different levels (farm, district, region, state/province, national). The concepts of spatial and temporal diversity and apparent and latent diversity are incorporated into the framework. We then identify different indices to represent each concept, explain the application of the diversity concepts and indices used for the analyses in this volume, and draw implications for economic analysis and the choice of diversity measure.
