Millets are recognised as the initial domesticated cereal grains, cultivated since the Neolithic Age. However, in recent decades, their significance has been overshadowed by other crops. The United Nations' declaration of 2023 as the International Year of Millets presents a unique opportunity to shed light on these ancient grains and their potential to transform our food systems. One of the central themes of the book is the exceptional nutritional benefits offered by millets. As climate change poses increasing challenges to agriculture, millets emerge as a promising solution for ensuring food security in a sustainable manner. The readers will gain a comprehensive understanding of how millets contribute to biodiversity, soil health, and water conservation. By fostering awareness and appreciation for these resilient grains, the book contributes to the global effort to build more sustainable, inclusive, and resilient food systems. By synthesising current knowledge, it will serve as a valuable reference for researchers, enabling them to build upon existing studies and explore novel avenues in millet research.
