The environmental balance needed for agriculture is severely strained due to changes in rainfall patterns and climate change, as well as the growing global need for food. As global temperatures rise and precipitation patterns become more erratic, millets offer an efficient solution to the trade-off between food security and water availability. Millets are rich in nutrients and possess a special ability to endure extreme conditions such as heat, drought, and various other abiotic and biotic stresses. Pearl millet is a highly climate-resilient crop capable of mitigating the adverse impacts of climate change. Antioxidant gene expression, presence of a waxy outer layer and heat shock proteins/chaperons contribute to its abiotic stress tolerance. By adjusting its flowering phenology and establishing fast-growing roots, pearl millet enhances its water and nutrient use efficiency. Stable sources of germplasm in pearl millet that exhibit resistance to diseases such as downy mildew, blast, rust, smut, and ergot have also been incorporated into disease resistance breeding programs. Pearl millet plays a crucial role in nourishing the poverty-stricken populations due to its high palatability and rich nutritional profile. Various bioactive compounds pertain to hypoglycemic, anticancerous and probiotic properties that contribute to its health benefits. Biofortification in pearl millet offers a solution to address issues of micronutrient deficiency in vulnerable populations. Continued research and investment in pearl millet production not only bolster food security but also contribute to the resilience of agricultural systems in the face of increasingly unpredictable environmental conditions. Thus, embracing pearl millet represents a forward-thinking approach to ensuring food security and promoting nutritional diversity on a global scale.
