Experts have highlighted Assam’s potential to expand makhana cultivation, also known as fox nut or gorgon nut, by scientifically utilising its extensive wetlands. The initiative could promote crop diversification, rural employment and agro-based entrepreneurship.

Key Facts and Potential

• Assam has nearly 1 lakh hectares of natural wetlands with potential for makhana cultivation. Its estimated natural growth area is around 40,000–50,000 hectares.
• Preliminary studies conducted in 2012 indicated that around 50–60 tonnes of makhana seeds were harvested annually from nearly 10,000 hectares in Jorhat, Sivasagar and Dibrugarh.
• Assam’s humid subtropical climate, high rainfall and abundant water resources favour makhana cultivation.
• Low-lying areas unsuitable for economically viable paddy cultivation can be considered for makhana farming through the field method.

Scientific Cultivation and Challenges

• According to Assam Agricultural University (AAU) experts, the field method requires approximately 1–1.5 feet of water depth and can offer higher productivity than traditional pond and beel cultivation.
• Maintaining 10–20% open water surface helps ensure sunlight penetration and aeration.
• Traditional cultivation requires deeper water, while sudden water-level fluctuations and premature drying of wetlands due to climate change can damage the crop.
• Lack of awareness, inadequate scientific cultivation practices, quality control and processing facilities remain major challenges.

Economic and Environmental Significance

• Makhana is valued as a nutritious food containing protein and 18 essential amino acids, with relatively low fat content.
• Its value chain can generate employment in harvesting, drying, grading, popping, packaging and marketing.
• Assam already has a makhana-popping industry. Strengthening local cultivation and processing could help meet demand across the Northeast and access national and international markets.
• Scientific land-use planning is essential to ensure that commercial cultivation does not damage wetland biodiversity and fisheries.

Exam Hook: Key Takeaway

Assam can transform its wetlands into productive agricultural assets through scientific makhana cultivation, but expansion must balance farmers’ income with wetland conservation.

Prelims Practice Question
