TL;DR: Significance This study provides evidence of change in the relative importance of different crop plants in national food supplies worldwide over the past 50 years, which heightens interdependence among countries in their food supplies, plant genetic resources, and nutritional priorities, and gives further urgency to nutrition development priorities aimed at bolstering food security.

TL;DR: Humanity depends on fewer than a dozen of the approximately 300,000 species of flowering plants for 80% of its caloric intake and capitalize on only a fraction of the genetic diversity that resides within each of these species.

TL;DR: It is concluded that a systematic effort is needed to improve the conservation and availability of crop wild relatives for use in plant breeding, using occurrence information collected from biodiversity, herbarium and gene bank databases.

TL;DR: The role that CWR play in modern crop breeding is documented, including their past and current use, advanced breeding methods and technologies that promise to facilitate the continued use, and what constraints continue to hinder increased use of CWR in breeding.

TL;DR: The Adapting Agriculture to Climate Change (AAC) project as mentioned in this paper aims to collect and protect the genetic diversity of a portfolio of plants with the characteristics required for adapting the world's most important food crops to climate change.
