March 15, 2014: Today, farmers of the Serhmun village would start a fire on the hills near Tuilut, to meet a deadline set by the state government. We were in Damparengpui, a remote village in Western Mizoram, from where we wanted Lal Sanga to take us in his autorickshaw up the bumpy, winding hill road to Tuilut.
“Do you really want to go all the way to see that?” he asked. It would turn out to be the loudest, hottest, most spectacular fire that I had witnessed at close range. A deliberate fire that would reduce to ashes what had been, until some weeks ago, a dense bamboo forest. And yet, the fire did not signify destruction as much as it did a new beginning.
Two spectacular bamboo dances, one celebrated, the other reviled, enliven the mountains of Mizoram, the small northeastern Indian state wedged between Bangladesh and Myanmar. In the first, the colourful Cheraw, Mizo girls dance as boys clap bamboo culms at their feet during the annual Chapchar Kut festival. The festival itself is linked to the other dance: the dance of the bamboos on Mizoram’s mountains brought about by the practice of shifting agriculture, locally called jhum or ‘lo’. In jhum, bamboo forests are cut, burnt, cultivated, and then rested and regenerated for several years until the next round of cultivation, making bamboos vanish and return on the slopes in a cyclic ecological dance of field and fallow, of farmer and forest. While Cheraw is cherished by all, jhum is actively discouraged by the State and the agri-horticulture bureaucracy. Although jhum is a regenerative system of organic farming, Mizoram State, the first in India to enact legislation to promote organic farming, is now pushing hard to eradicate jhum under its New Land Use Policy (NLUP).
Eagle’s eye-view: the jhum shifting agriculture landscape in Mizoram, northeast India. Note extensive cover of bamboo, secondary, and mature forests retained in landscape even as cleared jhum fields of the current year lie drying in the sun.
Organic farm: Soon after the field is burnt, the first rains appear, and fields become quickly covered in green.
Better land use: The jhum landscape mosaic of fields, regenerating fallows, and forests (on left) is a better form of land use and forest cover than monoculture oil palm plantations (on right).
At first I thought it is the people of Mizoram who use bamboo to perform their celebrated dance, the Cheraw. After months of field research in remote forests of this small state in northeastern India, I know now it is the other way round. Through its intimate influence on the people, it is the bamboo that does its own dance on the mountains of Mizoram.

A farmer’s eye-view of the jhum landscape, through the window of a bamboo hut in a jhum field: slashed fields waiting to be burnt, the previous year’s fallows, and slopes draped with regenerating bamboo forests.

A jhum fire burns the current year’s field, behind a bamboo hut perched on last year’s fallow already covered in green regrowth. The landscape around has all stages of succession from young to old bamboo forests, secondary forests of bamboo and trees, and patches of mature evergreen forests with trees in ravines, ridges, and other refugia (Serhmun village jhums near Tuilut, March 2014).
Can wildlife and slash-and-burn shifting agriculture coexist? This question led me into remote rainforests of northeast India in 1994 for a field research study in Dampa Tiger Reserve, Mizoram. In December 2013, nearly two decades later, I went there again. From the Anamalai hills in south India, I travelled across the country to initiate a comprehensive bird survey in Dampa, including a resurvey of my old field sites. As a prelude to other writings I will post here in the days ahead, I post below an edited version of an article about my work in Dampa in the mid 1990s. This article first appeared in the May/June 2007 issue of Wildlife Conservation magazine (a remarkable periodical published by the Wildlife Conservation Society, which after a print run of over 112 years, perished with the recession in 2009). Original PDF here.

In the early years of forest succession, bamboos establish rapidly and dominate the vegetation, along with some pioneer trees.

The heat from the fire is intense, even from a hundred metres away. The entire slope is ablaze. Piles of slashed vegetation and tens of thousands of bamboo culms that had sun-dried for three months burn ferociously. The bamboo hisses, crackles, and explodes, audible a mile away. Hot gusts of wind scud the fire upslope, throwing branches and small trees ten metres into the air. High above, unmindful of the billowing fumes, swallows and drongos, in a frenzy of activity, hawk insects. Ash and smoke darken the sky, reducing the sun to a dull orange ball. In twenty minutes, almost as rapidly as it started, the fiery spectacle ends. On the soil, only a blanket of smoldering ash and tree trunks remain.
