The Near-Extinction and Revival of Kalanamak Rice

A grain that survived 2,600 years — wars, famines, dynastic collapses, the introduction of entirely new agricultural systems — almost did not survive the twentieth century. The Green Revolution, which saved tens of millions from famine, also cost India's agricultural diversity enormously. Kalanamak was among the casualties. What saved it was a combination of scientific determination, policy support, and the stubbornness of a small number of farming families who never stopped growing it even when it made no economic sense. This is that story.

Before the fall: Kalanamak's pre-Green Revolution status

For most of its 2,600-year history, Kalanamak was the dominant aromatic rice of the Eastern UP Terai. It was grown not because it was economically optimal — yield calculations were not how traditional farmers thought — but because it was the rice they knew, the rice their soil produced, and the rice their communities valued. It commanded a modest premium at local markets. It was used in festivals, gifted at weddings, served to guests.

The ecosystem around it was stable. Farmers saved seed from the best plants at each harvest. The cultivation knowledge — the transplanting spacing, the water management, the harvest timing, the traditional milling methods — was transmitted orally and practically within families and communities. The grain's identity was inseparable from the identity of the farming communities that grew it.

As late as the 1950s, Kalanamak was grown across substantial acreage in Siddharthnagar (then Basti district), Gorakhpur, and Maharajganj. The varieties were not formally documented or gene-banked at this point — nobody imagined they needed to be. Full history from 600 BCE to present →

How the Green Revolution caused the collapse

The Indian Green Revolution began in earnest in the late 1960s with the introduction of IR8 and its successors — semi-dwarf, high-yield, fertiliser-responsive rice varieties developed at IRRI (ironically, the same institution that would later help save Kalanamak). The policy response was comprehensive: subsidised fertiliser, subsidised water, procurement guarantees at minimum support prices, and agricultural extension services all aligned to promote the new varieties.

For a farmer in Siddharthnagar, the calculation was stark. A high-yield variety produced two to three times more grain per acre, matured in 90–110 days (allowing two crops in some areas, and reducing risk from late monsoons), and was bought at government-guaranteed prices. Kalanamak, by contrast, took 140–150 days, produced less, had taller straw that lodged more easily, and received no government procurement support. The local premium was not large enough to compensate.

Family by family, the switch happened. Each year, fewer farmers planted Kalanamak. The seed stock that was not planted was not saved. By the 1990s, large areas of Siddharthnagar that had grown Kalanamak for centuries had converted entirely to hybrid varieties. The gene diversity within the Kalanamak population narrowed as the number of seed-saving farmers shrank.

What kept Kalanamak alive

Two things saved Kalanamak from complete extinction. First, a small number of farming families in the Terai — particularly around the Siddharthnagar block — never stopped growing it, on small plots, for home consumption and local sale. These families, growing Kalanamak alongside the hybrid rice that dominated their income, were the living seed banks. Their reasons were not economic — they were cultural, habitual, and in some cases purely a matter of taste: they preferred the grain they had always eaten.

Second, the ICAR gene bank and the National Bureau of Plant Genetic Resources (NBPGR) had collected and preserved accessions of Kalanamak and related Eastern UP aromatic rice varieties during systematic germplasm collection efforts in the 1970s and 1980s. These preserved samples in cold storage provided a backstop — a set of reference genotypes that could be retrieved even if field cultivation had collapsed entirely.

The combination of living farmer-maintained seed and institutional cold-storage collections meant that when the revival moment came, there was something to revive.

The 2012 revival: method and people

By the late 2000s, the political and economic context had shifted. India's food security was more stable. Heritage foods were attracting urban consumer interest. The One District One Product initiative was developing. And scientific interest in low-GI and aromatic rice had grown — research on the BADH2 gene and 2-AP aroma production had placed Kalanamak in academic literature as a scientifically interesting variety.

Dr. R.C. Chaudhary, working with IRRI and in partnership with the UP state agriculture department, led the effort to collect, evaluate, and multiply the remaining Kalanamak diversity. The programme identified 14 distinct traditional accessions — representing the surviving genetic diversity of the Kalanamak population. Each was grown out, characterised for aroma intensity, grain quality, disease resistance, yield, and maturity duration.

The critical decision in the revival was to resist the temptation to cross Kalanamak with high-yield varieties to improve yield. Hybridisation would have given higher productivity — but at the cost of the specific BADH2 allele expression and Terai-adapted genetics that define authentic Kalanamak. The programme's guiding principle was authenticity over yield. The best-performing pure Kalanamak lines were selected and multiplied as foundation seed.

This foundation seed was then distributed to farmer cooperatives in Siddharthnagar, Gorakhpur, and Maharajganj, along with technical training on organic and low-input cultivation, water management for long-duration varieties, and market linkage to premium buyers. The programme created a virtuous cycle: better seed + better practices + better prices = more farmers willing to return to Kalanamak. Dr. Chaudhary and the revival science in detail →

How the GI tag reinforced the revival

The GI tag granted in 2013 arrived at the moment the revival most needed legal backing. Without it, any trader could have labelled ordinary aromatic rice as "Kalanamak" once the name began building a premium market. This would have collapsed farm-gate prices and destroyed the economic case for growing the real grain.

The GI tag created an enforceable barrier. Only certified-origin Kalanamak from the designated Terai districts could legally use the name. This simultaneously protected farmers' ability to command a premium and gave consumers a legal basis for authenticity expectations. What the GI tag means in detail →
