In this article we investigate contribution these risks, through compilation comprehensive dataset multi-indicator assessment diversity. Our results show that most world (127 countries territories, 87% global population) achieves high levels potential (≥6 nutrients fulfilled), however only 33% population (41 countries) fully self-sufficient.
