Physical infrastructure: storage, warehouse receipts and cold chains

Detail

1. Why physical infrastructure is a government measure

• Where it sits: NCERT (Class 11, Rural Development) lists physical infrastructure as the second government measure for improving agricultural marketing.
• The first measure is regulating markets.

• The later measures are cooperative marketing and policy tools such as MSP, buffer stocks and PDS.

• What the state provides: roads, railways, warehouses, godowns, cold storages and processing units.

• NCERT's judgement: these facilities are "quite inadequate" for the growing demand.
• Why it matters:
• Without storage, a farmer must sell right after harvest, when supply is at its peak and prices are lowest. This is called distress sale.
• Without transport, the farmer cannot reach a better market.
• Without cold chains, perishable crops rot within days.

2. Post-harvest losses

• Definition: post-harvest losses are the loss in quantity and quality of produce between harvest and consumption. They come from poor storage, handling, transport and processing.
• NCERT figure: "more than 10 per cent of goods produced in farms are wasted due to lack of storage".
• NABCONS study (2022):
• NABCONS is NABARD Consultancy Services. The Ministry of Food Processing Industries commissioned the study in 2022, with 2020-22 as the reference period [6].
• It covered 54 crops/commodities across the country [6].
• Measured losses were 3.89%-5.92% for cereals, 5.65%-6.74% for pulses and 2.87%-7.51% for other categories [6]. (NCERT scaffold: cereals about 4-6%.)

• Scaffold figures: total loss of about ₹1.5 lakh crore a year, with the highest losses in fruits (about 6-15%) and vegetables (about 5-12%) (verify current).

• Worked example (illustrative):

• A farmer harvests 100 quintals of wheat and the loss rate is 5%.
• Loss = 100 × 5% = 5 quintals.
• At ₹2,400 per quintal, that is ₹12,000 lost before the grain reaches anyone's plate.
• For tomatoes at 12% loss, the same 100 quintals would lose 12 quintals. This is why perishables need cold chains most.

3. Warehouses, godowns and cold storages: definitions

• Warehouse (Class 7, Understanding Markets): a large building for storing goods before they are sold.

• Wholesalers store grain in godowns (Figs 12.13-12.14). A godown is a storage shed for grain or goods.

• Cold storage (Fig. 12.12): a special warehouse kept at low temperature to preserve perishables (goods that spoil fast, such as fruits, vegetables, milk and fish).

• Current cold storage stock: India has 8,653 cold storages with a capacity of 394.17 lakh MT [7].

4. Storage institutions

Institution	Role
Central Warehousing Corporation (CWC), 1957	A central public-sector body that builds and runs warehouses for farmers, traders and government agencies
State Warehousing Corporations (SWCs)	State-level bodies that run warehouses and often store the FCI's and states' procured grain
Food Corporation of India (FCI)	Stores central buffer stocks (reserve grain stocks) in owned plus hired capacity (hired from CWC, SWCs, private parties and PACS) (verify current figures)
WDRA, 2010	Regulates warehouses and the warehouse-receipt system (see section 5)
PACS (Primary Agricultural Credit Societies)	Village-level cooperatives, now being used as sites for new godowns (see section 7)

• Push to register FCI-used warehouses: the Minister pressed for FCI-used warehouses in the states to be registered with WDRA. More than 4,800 warehouses are WDRA-registered [2].

5. From receipt to e-receipt

Instrument	What it is
Warehouse receipt	A document from a warehouse saying that goods have been deposited. It can be used as collateral (security given to a lender) for credit.
Negotiable warehouse receipt (NWR)	A receipt that can be transferred by endorsement (signing it over). The stored goods can be sold or pledged for a loan without being physically moved.
Electronic NWR (e-NWR)	A digital NWR issued by a WDRA-registered warehouse and held on a repository (a digital record-keeper, like a demat depository). It makes pledge finance and trading easier and forgery harder.

• Legal base: the Warehousing (Development and Regulation) Act, 2007 set up the WDRA (Warehousing Development and Regulatory Authority) in 2010.
• e-NWR launch: the e-NWR system was launched by the Union Food Minister, Shri Ram Vilas Paswan [9].
• e-Kisan Upaj Nidhi (e-KUN) portal, 2024:
• It is WDRA's digital gateway. It aims to make warehousing easier for farmers and help them get fair prices [2].
• Farmers can store produce in any WDRA-registered warehouse through a simple digital process. PIB describes terms of 6 months at 7% a year (verify current) [2].

• Farmers can take loans against the e-NWR. They can use these loans to repay their KCC (Kisan Credit Card) loan [2].

• RBI support through priority sector lending (PSL):

• PSL is the rule that banks must lend a set share of their credit to sectors such as agriculture.
• RBI raised the PSL loan limit against e-NWRs from ₹50 lakh to ₹75 lakh. The limit for other (non-electronic) warehouse receipts stays at ₹50 lakh [2][3].
• This gives banks a reason to prefer the electronic receipt.

6. Why warehouse receipts matter: stop distress sale

• The chain of cause and effect:
• The farmer deposits grain in a registered warehouse and gets an e-NWR.
• The farmer pledges the e-NWR to a bank and gets a loan at once.

• The farmer waits for prices to rise after the harvest glut, then sells and repays the loan.

• Worked example (illustrative numbers):

• Stock: 100 quintals of wheat. Harvest price ₹2,200 per quintal, so value = ₹2,20,000.
• The bank lends 70% of value = ₹1,54,000.
• Interest at 7% a year for 4 months = 1,54,000 × 0.07 × 4/12 ≈ ₹3,593.
• Four months later the price is ₹2,450 per quintal. Extra revenue = 100 × ₹250 = ₹25,000.

• Net gain before storage charges ≈ ₹25,000 − ₹3,593 = ₹21,407.

• Links: see pledge loans in financial-inclusion-rural-credit. A warehouse receipt also lets the farmer sell online through platforms like e-NAM without moving the grain.

7. Grain storage in the cooperative sector (2023)

• What it is: the "World's Largest Grain Storage Plan in Cooperative Sector", approved on 31 May 2023 as a pilot project. Its aim is to fix the shortage of foodgrain storage capacity [8].
• What gets built: agri-infrastructure at PACS level: godowns, custom hiring centres (where farmers rent machines), processing units and similar facilities [8].
• How it is funded: through convergence (joining together) of existing schemes: AIF, the Agricultural Marketing Infrastructure (AMI) scheme, SMAM (Sub-Mission on Agricultural Mechanization) and PMFME (PM Formalisation of Micro Food Processing Enterprises) [8].
• Progress:
• Earlier stage: 560 societies identified, 120 godowns completed, 72,702 MT of capacity [8].

• By July 2026: 1,012 PACS identified and godowns completed in 313 PACS, creating more than 1.80 lakh MT of capacity [8].

• FCI support:

• FCI gives a uniform 9-year hiring assurance to PACS godowns of 2,500 MT or more. This is a promise to rent the space, so PACS can repay their loans [8].

• FCI has mapped a need of about 26.03 lakh MT of storage at 216 locations in 18 States/UTs [8].

• Cheap credit: with AIF's 3% interest subvention (a cut in the interest rate that the government pays for), the effective loan rate for PACS falls to about 1% [8].

8. Cold chains

• Definition: a cold chain is an unbroken, temperature-controlled chain of storage and transport. It preserves fruits, vegetables, dairy and fish.
• The links in the chain: pack-house → pre-cooling → reefer truck → cold store → ripening chamber → retail.
• Pack-house: a shed near the farm for sorting, grading and packing.
• Pre-cooling: quickly removing field heat just after harvest.
• Reefer truck: a refrigerated truck.

• Ripening chamber: a room for controlled ripening, for example of bananas and mangoes.

• Why the chain must be unbroken: if even one link is missing, for example no reefer truck, the produce warms up and spoils. The cold store at the next stage is then wasted.

9. Cold-chain and allied schemes

Scheme	Year	Key point
National Centre for Cold-chain Development (NCCD)	2011	Plans and sets standards for cold-chain development
PM Kisan Sampada Yojana	—	Umbrella scheme of the Ministry of Food Processing Industries for food processing and cold-chain infrastructure. It includes Integrated Cold Chain and Value Addition Infrastructure (ICCVAI) [10]
Operation Greens	2018	Began for Tomato, Onion, Potato ("TOP"); widened to 22 perishables in 2021
Kisan Rail	2020	Rail transport for perishables
Agriculture Infrastructure Fund (AIF)	2020	₹1 lakh crore financing facility for post-harvest infrastructure, with 3% interest subvention
Grain storage plan (cooperatives)	2023	PACS-level godowns (section 7)

• AIF details:
• Corpus: ₹1 lakh crore, for post-harvest management and community farming assets such as cold storages, warehouses and processing units [4].
• Loan terms: collateral-free term loans of up to ₹2 crore, with 3% a year interest subvention [4].
• Progress from July 2020 to 26 January 2026: ₹80,224.15 crore sanctioned for 1,50,431 projects, which brought in total investment of ₹1,27,508 crore [4].

• Cold storage under AIF: 2,454 cold storage projects sanctioned, worth ₹8,258 crore [5].

• Effect of the schemes: a NABCONS evaluation (2020) found that the cold-chain scheme cut wastage sharply, especially in fruits and vegetables, dairy and fisheries [10].

10. Remaining gaps

• Wrong mix: cold storage is skewed towards potatoes, mostly single-commodity stores in UP and West Bengal. Fruits, vegetables and fish get far less.
• Thin reefer transport: there are too few refrigerated trucks and rail wagons. The chain breaks in transit.
• Weak first mile: there are too few pack-houses and ripening chambers near farms. Produce loses quality before it reaches any cold store.
• Low reach of receipts: only 4,800+ warehouses are WDRA-registered against a target of 1 lakh [2]. Many small farmers still cannot use e-NWR finance.
• Scale of public grain storage: at 1.80 lakh MT built by July 2026 against an FCI-mapped need of 26.03 lakh MT, the cooperative storage plan is still at an early stage [8].

Prelims Hooks

• WDRA was set up in 2010 under the Warehousing (Development and Regulation) Act, 2007. It regulates warehouses and negotiable warehouse receipts.
• Central Warehousing Corporation was set up in 1957. Trap: it is not the same as FCI, which was set up in 1965.
• e-NWR: issued only by a WDRA-registered warehouse, held on a repository, and transferable and pledgeable without moving the goods.
• e-Kisan Upaj Nidhi (2024) is WDRA's digital portal for storage and pledge loans against e-NWRs [2].
• RBI PSL limit: ₹75 lakh for loans against e-NWRs, versus ₹50 lakh for other warehouse receipts [2][3].
• AIF (2020): ₹1 lakh crore corpus; collateral-free loans up to ₹2 crore; 3% interest subvention [4].
• NABCONS post-harvest loss study (2022): reference period 2020-22, 54 crops; cereal losses 3.89%-5.92% [6].
• Operation Greens (2018): TOP = Tomato, Onion, Potato; widened to 22 perishables in 2021.
• Grain storage plan in cooperative sector: approved 31 May 2023; godowns at PACS level; FCI gives a 9-year hiring assurance for godowns of 2,500 MT or more [8].
• Cold storage stock: 8,653 units with 394.17 lakh MT capacity, skewed towards potatoes in UP and West Bengal [7].

Mains Points

• Storage plus credit is a market reform in itself:
• The e-NWR, pledge loan and e-NAM together let farmers choose when and where to sell.
• This weakens distress sale and the hold of the local trader-lender, without any change to the APMC law.

• It also reaches crops and farmers that MSP procurement does not cover.

• Decentralised storage and PDS efficiency:

• PACS godowns bring storage closer to the farm, so there is less transport and less loss.
• They also give FCI local hired capacity for buffer stocks.

• The risks are PACS governance, low use of the space, and a heavy dependence on FCI's hiring promise.

• The cold-chain mismatch:

• India has about 394 lakh MT of cold storage, but it is mostly potato stores in two states.
• Losses are highest in fruits and vegetables, where pack-houses, reefers and ripening chambers are missing.

• So policy should fund the missing links (first-mile and transport), not just more storage capacity. AIF and PMKSY should be judged on this.

• Private investment and the farm-law debate (2020-21):

• Removing stock limits was meant to draw private money into warehouses and cold chains.
• After the laws were repealed, credit-linked subsidies (AIF, 3% subvention) are now the main tool for building post-harvest infrastructure.
