Discuss the significance of makhana cultivation in India with reference to livelihood security, nutrition, and export potential. How do recent government initiatives aim to strengthen this sector?
Makhana (fox nut), derived from the aquatic plant Euryale ferox, is an indigenous crop that occupies a unique niche in India’s agricultural and nutritional landscape. India produces nearly 80% of the world’s makhana, reinforcing its global dominance in this sector. Cultivated mainly in wetlands and shallow ponds, particularly in eastern India, makhana represents a convergence of livelihood security, nutrition security, and export potential. Recognising this, the government has recently established the National Makhana Board and approved a ₹476.03 crore central scheme (2025–31) to strengthen the value chain.
To unlock this potential, the government has taken targeted policy measures:
Makhana cultivation exemplifies how a traditional, region-specific crop can address contemporary challenges of rural livelihoods, nutrition security, and export diversification. With focused institutional support through the National Makhana Board and sustained investment under the new scheme, makhana has the potential to emerge as a flagship niche agri-export, contributing to sustainable agriculture, inclusive growth, and India’s global food leadership.
