Climate change, water scarcity, population growth, rising food prices, and other socioeconomic
repercussions are anticipated to pose a danger to agriculture and global food security in the
twenty-first century, especially for the world's poorest residents of arid and subarid countries.
We must concentrate on dry lands to significantly boost the production of grains because

agricultural fields with irrigation systems have been fully utilized. Utilizing arid areas to
produce sufficient quality grains is difficult because of their poor productivity. The most
important source of food in the world is cereal grains, which also play an important part in the
global diet of people. In the semiarid tropics of Africa and Asia, millet is one of the most
significant drought-resistant crops and is a major source of carbohydrates and proteins for the
local population. Additionally, millet grain is currently attracting more interest from food
scientists, technologists, and nutritionists due to its significant contribution to national food
security and potential health advantages. The phytochemicals found in millet grains have a
beneficial impact on human health by reducing phytates and cholesterol levels. The quest for
substitute grains is necessary to relieve the pressure caused by the frenetic demands on
cereals and their uses in numerous industries. The performance improved when pearl and finger
millets were substituted for maize in the diets of several animals. In terms of poor growth
conditions and high nutritional value, millets outperform other grains like wheat and rice as
crops that are climate change compliant. These strategies will aid in the fight against hunger
and malnutrition while also providing monetary benefits to the millet growers and other
stakeholders.
