Evaluate the effectiveness of Aadhaar-based authentication in reducing leakages in agricultural input subsidies.

Agricultural input subsidies, dominated by a fertilizer subsidy outlay of about ₹1.91 lakh crore [4], were historically leaked through diversion and ghost beneficiaries. Aadhaar-based authentication, operationalised through PoS-enabled DBT in Fertilizers, has substantially plugged delivery-end leakage, though it addresses only part of the problem.

Where it has worked

• Payment linked to verified sale: 100% subsidy is released to fertilizer companies only on actual sales to buyers authenticated via Aadhaar through PoS devices at every retail shop [2], replacing payment on mere dispatch to the wholesaler.
• Universal coverage: DBT was rolled out across all States/UTs by 1 March 2018, making authentication the default retail transaction mode nationwide [1].
• Real-time traceability: the Integrated Fertilizer Management System (iFMS) captures production, movement, availability and sale, enabling the Department of Fertilizers to monitor stocks in real time and curb diversion to industrial or cross-border use [3].
• Administrative capacity built: roughly 1.8 lakh retailers were trained across 4,630 sessions, embedding the system at the last mile [5].

Where it falls short

• Exclusion risk: biometric failure, poor rural connectivity or missing Aadhaar can deny a genuine cultivator timely inputs at sowing time; alternate IDs such as KCC and Voter ID were therefore permitted [1].
• No cap on quantity per farmer: authentication verifies who buys, not how much is agronomically needed, so over-use of urea and nutrient imbalance persist.
• Tenant farmers and sharecroppers without land records remain weakly covered.
• Price distortion untouched: leakage is driven by the wide gap between subsidised and market prices, which only Nutrient-Based Subsidy rationalisation and pricing reform can narrow [6].

On balance, Aadhaar authentication has been an effective delivery-side reform — it has made subsidy payment evidence-based and traceable — but it is a verification tool, not a subsidy-reform strategy. Coupling it with soil-health-linked entitlement limits, tenant registration and gradual price rationalisation would convert transparency into genuine efficiency in farm input support.
