6 impossible things a coffee lover can do before breakfast

1. Wake up and smell the coffee. No, not the coffee brewing in your percolator or stove-top at home, this coffee has not been a bean yet. Far sweeter, heady, finer than jasmine, it suffuses the air all around, seeps into your lungs inside, bathes you in fragrance outside. It emerges, imperceptibly, from millions of soft, white-petaled flowers packed along the branches of waist-high bushes ranging all around you under the shade of rainforest trees. A week earlier and you would have barely seen the waiting green buds clustered at leaf axils, a week later and the spent blooms would have wilted away. You arrive on exactly the right morning, a week after the first rains of summer, at the tropical coffee plantation in glorious, copious, synchronous bloom.

2. Listen to the morning buzz. No, this is not the artificial twitter of virtual voices flickering out of your phone or computer screens. This is the real thing: the morning chorus of birds carrying the sibilant twitter of sunbirds and white-eyes, alongside the clarion clang of racket-tailed drongos, the rhythmic metronome of barbets, and the raucous cries of great hornbills. All around sounds the delicate, pervasive hum of pollinating bees—small stingless bees, striped honey bees, giant rock bees—all living up to their clade name, anthophila, the flower lovers. Dip into the flower, sip the nectar, shrink and become the bee.

3. Share and savour a bole of fruit. The jackfruit, like disfigured, spiky footballs, hang heavy from the knobbly bole of the shade tree. A macaque has eaten a monkey’s mouthful out of one, revealing oozy white latex and pulpy yellow innards. Now, the leaves shiver behind a leaping red-black blur. Cream-faced, tuft-eared, bushy-tailed, the giant squirrel soft-lands on branch, scurries to bole. Hanging by his hind feet, he pulls a marble-sized seed wrapped in pulpy flesh to his mouth. Later the fruit could fall or be yanked down by a hungry elephant. Take a bite yourself. Savour the fruit of giants.

4. Eyeball the headlines. Look up the news: for instance, about yesterday’s gathering of eminent area residents at the annual jack feast. Parallel furrows on tree bark show Sambar had stripped off a snack, just before Elephant came by after her mud bath and rubbed herself on the trunk. By night, Civet came for the rainforest fruit platter, placed a seed-studded scat on a rock as his mark of approval. Porcupine left a quill behind, unexplained. You can only surmise what the writers on this landscape are up to, or mean, by the marks they leave behind.

5. Clean up after. A tiny bird, small enough to hold in your fist, shows you how. The flowerpecker flits above among the mistletoes adorning tree branches like Christmas decorations. With his beak, the bird pinches the mistletoe fruit, sticky to touch, to pop the seed and wipe it off on a twig. Or he swallows it and will later have to wipe the goopy seed off his butt on a twig where the seed will grow into a future mistletoe. Biologists call this directed dispersal, but there’s something even more admirable in what the little fella does that you could emulate: don’t just wipe stuff off, regenerate what you consume.

6. Read the coffee grounds. Open all your senses, sip your brew now: imbibe a little of the land of elephant and hornbill and civet in India, or the land of tamandua and toucan and coati in Costa Rica, or whichever tropical place made your coffee. (You didn’t think you made it yourself, did you?) Look in the cup, imagine a future where you will cherish and feel connected to lives and lands so impossibly wonderful wherever they are.

Blowin’ in the wind — II

From a boat on Assam’s Deepor Beel—the freshwater lake lying south-west of Guwahati, the largest city in India’s northeast—you can look east past thousands of waterbirds and a carpet of floating leaves to see the city’s seething, smoking garbage dump. Under spotless blue skies, a thin brown haze blankets the lake from fringing forest to quarried hillock, from skirting township to the Boragaon dumpyard. As another dump truck lurches to a halt and tips its load of filth over, an unruly mob of Black Kites and a cloud of dark mynas explode from the murky earth flapping like pieces of tattered cloth caught in a gust. The truck deposits another mound of unsegregated waste—a fraction of the more than 600 tons generated daily from the city of nearly a million people—all plastic and putrefaction, chicken heads and pigs entrails, street dirt and kitchen waste, broken glass and soiled cloth, bulbs and batteries and wires and electronics and metal and paper and more. Beside the truck waits a line of people: women, adolescents, and children. And behind them, a phalanx of Greater Adjutant storks—tall, ungainly birds with dagger-like beaks and naked yellow and pink necks—awaits its turn.

In company with cattle and dogs, the people will scavenge first. Driven by poverty, with little or no land or possessions of their own, the women and children from poor families living around the lake have turned to the dumpyard, despite its appalling prospects for their health, to scour a livelihood from the residues of urbanisation. In the waste thrown out of home and market, hospital and motel, collected and dumped again by the trucks, in that twice-discarded garbage, they will rummage to gather things to sell, to use, to survive. Without even a cloth draped over their noses against smoke and stench, they will sift valuable scraps from the offal with metal hooks and bare hands.

Then, it will be the turn of the Greater Adjutants. The birds will parade over the dump, pick up and swallow rotting meat, skins, and bones, fish tails and goat’s ears, eyeballs and hooves, and some will carry it back to their nests on tall trees in villages kilometres away, to regurgitate and feed their hungry chicks. The stork, whose world population is estimated at around 1200 – 1800 mature individuals, about 650 – 800 of which lives in Assam, is considered endangered, its population trending downhill. Yet, there are days when nearly half the world population may be seen in the city of Guwahati, congregating at the garbage dump. In its decline, the stork has learned to survive off the thrice-discarded filth of humanity.

With the reek of burning, decaying garbage, the air carries the keening of flies and mosquitoes, the chatter of women and children, the clatter of stork beaks. The air lies thick, in humid vapours that burn the nostrils, clog the windpipe, catch at the throat as if to stifle the breath of life. And above it all, a twister of storks turns slowly, as the lanky birds rise and rise, in a thermal spiral, wings held wide, yellow pouches hanging at their throats, like penitent beings weighed by remorse heading to the heavens.

Seated on low thwarts, the three of us are rowed out by the boatman into Deepor Beel. The floodplain lake, a now-festering fragment of the great River Brahmaputra that has swung its course to the north, is a Ramsar site, a wetland of international importance. Every year, thousands of waterbirds gather at the lake, from resident swamphens, lapwings, and herons, to wintering migrant shorebirds, ducks, and geese. Rowing in deeper water or punting through shallows with his oar, the boatman guides the flat-bottomed boat, freshly waterproofed with sticky black tar, over water clouded with sediment and plankton, towards the distant flocks of waterbirds. The boat skims the canopy of a swaying forest of soft underwater plants, topped by floating waterlily leaves that look like plates, like expanded hearts.

Fed by river and rain, the lake receives water and storm runoff along feeder streams and drains. It mixes city wastewater with the purer flows from the hills of the Rani and Garbhanga Reserved Forests to the south. Polluted by pesticide and fertilizer runoff, contaminated with fecal bacteria, muddied by erosion and sewage, Deepor Beel is slowly turning into ditchwater. Hemmed in between stolid hills and restive city, pincered by highways to the east and west, cleaved from the southern forests by road and railway line, the lake is shrinking, too. Over two decades beginning in 1991, Deepor beel lost 41 per cent of its open water, the area shrank from 712 hectares to 421 hectares and became more fragmented. With the loss of wetland area, the birds, too, appear to be in decline. Only the city and its impressive garbage dump are growing and growing.

On the lake, the water parts for our boat, closes in our wake, the parted plants mark our passage on the surface. In distant boats, fishermen fling their cast nets onto open water, or pull at their nets, stooping to pick their day’s catch from the tangle. Our boat slips over a long, taut fishing net stretched wide across the lake; the water is calm, now it is the horizon that is swaying. To the west vehicles ply on the busy highway, to the north the city burgeons, to the east the unsavoury Boragaon dumpyard moulders, and to the south a train thunders along the railway.

The tracks shrill and clatter under metal wheels, as they will almost every hour: the trains will not stop. There is blood on these tracks, the blood of elephants—herds, calves, tuskers—who tried to cross the tracks from the forest seeking water and forage in the lake. The elephants were slammed, were dragged, were extinguished: a slaughter wrought in passivity, for who, in their right mind, will attribute active intent to trains? Only the journeys of the elephants, the lives of the elephants, shall come to a stop.

The clamour of hundreds of whistling-ducks accompanies our passage, their pulsed whistles and squeals lance over the water. Suddenly, the air reverberates with wings. The resounding beat and rush of wings roils the air overhead, as hundreds of pintail ducks and greylag geese take wing from rippling lake to splayed-out sky.

Deepor_Beel_low_DivyaMudappa

The storks still soar in the distance. From high, they must see the vast braid of the Brahmaputra winding through the landscape. They must see, far, far to the north, the grandeur of Himalayan peaks, dusted with snow and weighed by glacier. They must see that the lake below is but a drop of water on land. The ducks and geese wheel and quarter, they sweep and swerve in the air. They begin to descend, as the storks do, too, out of seamless, unmarked skies.

As dusk settles over the landscape and the milling flocks of birds settle for their roost, the fishermen return to their villages in their boats. The trucks and trains have passed, and perhaps the elephants have, too.

By night, as the city flickers to life before us, the garbage dump, its people, its birds, all become invisible. Tomorrow, the fishers will return to the lake, and the women and children to the dump. And, from the skies above Guwahati, it is again to the lake and garbage dump that the birds, too, must drop.

…Yes, ’n’ how many ears must one man have
Before he can hear people cry?
Yes, ’n’ how many deaths will it take till he knows
That too many people have died?
The answer, my friend, is blowin’ in the wind
The answer is blowin’ in the wind

The walk that spun the world

Vermont_landscape

It starts as a walk in a forest in Vermont, which takes me, strangely enough, into the high Himalaya. On a balmy July afternoon, with hesitant clouds massing out west, I set out on foot down the road that passes through the village of Craftsbury Common, Vermont. I leave behind the public library and the silent church whose spire towers over the open meadow of the commons and the white clapboard houses in the village. Ahead, the forest appears, flushed green and dense and dark from summer rains. Open fields, loon lakes, and lush farms adorn the landscape, but it is the tranquil forest that entices me in. Almost involuntarily, I am drawn into the woods, up the winding trail that disappears into darkness.

On the trail, the dark, wet earth carries the tread of tyres and the stamp of boots overlaid by tracks of deer and spoor of weasel. The imprints attest a land that the animals share with people. Shafts of evening sun brighten the canopy with amber light, but little reaches down into the shaded undergrowth. Much is still hidden from my eyes.

Vermont forest trail

* * *

I pause where the tracks of the deer swerve into the forest. The print is now no more than a suggestion. I follow, stepping off the trail into the trees. The ground feels soft underfoot, matted by pine leaves and litter, sprigs of tiny grasses, a coterie of creepers, mounds of moss. Standing shoulder-to-shoulder with me in the undergrowth, saplings of red and sugar maples jostle basswood and hemlock in the eternal clamour for light.

In a gap, a tree stump stands testimony to logging—not the rampant clear-cutting of a more reckless past, but a mindful selection of a woodsman. The forest is still used by people. If the trail and bootprints are not evidence enough, the pails and pipes strapped to trees reveal the touch of people tapping the syrupy sweetness of maples. And further down, a stack of logs waits beside the trail to be hauled and hewn into canoe or board or burned for warmth in kitchen and hearth.

Inside forest VT

As I look up at trees that stand tall without being colossal, I sense the passage of decades rather than centuries. Yet, this land has witnessed a great flux of trees over the ages. As ice-age glaciers retreated around 11,000 years ago, forests appeared on the open lands. In the warmer world that followed, vast tracts of forest arose, in which native Americans lived and hunted for thousands of years. Colonial settler populations surged from the 1760s and in the ensuing decades clear-felled millions of acres of forests for timber and to open land for farms in New England. By the 1850s, around three-fourths of Vermont was open land: farms and sheep pastures bounded by long walls of stacked stone slabs. Then, in the mid-nineteenth century, the tide in people and land turned, as civil war and migration whittled the settlers and rested the farms, bringing a great resurgence of trees to clothe the landscape. Today, forests once again cover over three-fourths of Vermont. In the forests, assisted by conservation efforts, resident wildlife species such as moose, grouse, beaver, and marten are staging a comeback in a propitious rewilding of the New England landscape.

Vermont_forest

Stone wall VermontFrom where I stand, the river on which the timbers were once floated, like giant rafts of huge logs spanning bank to bank, is distant and hidden. Nearby, a moss-felted, lichen-blotched stone wall of an old farm crumbles into a linear tumulus weaving through trees.

The land still carries the marks of history. If I could read the rings in the recumbent trees or discern the trajectory of the resurgent landscape, I would understand better the revival of forest on exploited lands. Perhaps then, I would also perceive what it was that brought respite and respect for trees, in this momentous transformation in America’s environmental history. In 1864, at the cusp of that great turnaround from clear-cuts and farms to forest, as the nation underwent the upheavals of civil war and the civil rights movement, Vermonter George Perkins Marsh’s Man and Nature; Or, Physical Geography as Modified by Human Action appeared, a book that was to deeply influence the conservation movement. Now, a century and a half later, embracing the insights from environmental history, conservationists are better placed to resolve the “great question” with which Marsh concluded his book: the question as to “whether man is of nature or above her”.

If nothing else, the tracks on the trail suggest the human footprint can now be a soft one, too.

* * *

Looking at deer tracks, I ponder over my own journey. I have travelled from India to Vermont to join a workshop on writing about the natural world. Here, I know, I am a stranger still. Yet, that is not what I feel in the forest. Watchful, wistful, I meander through tall conifers, modest maples, beech, and ash. Taking a turn, my walk through the trees becomes a trek through stately forests of conifers, ash, and oak on great mountains. In a forest above a landscape of farm terraces and pastures, I am walking in the Garhwal Himalaya.

It is a landscape and people with a special place in India’s environmental history. For over a century, the colonial British government, followed by Indian foresters, exploited these Himalayan forests, taking timber and tapping pines, for products ranging from bats and boards to resin and railway crossties. Even as the State felled forests for commercial and industrial uses, it restricted access of local people to trees and forests for livelihood needs. In 1970, severe erosion and floods raised concerns about the widespread impacts of deforestation. Three years later, near the village of Mandal, government authorities curtailed access of local people to ash trees but allotted felling permits for the same trees to Symonds, a sports goods company. This drew the simmering tensions to a point of taut confrontation and more than a century of resistance boiled over into a new movement of non-violent action: Chipko. By the act of hugging trees marked for felling, supported by sustained protests, villagers, including groups of women, saved forests and livelihoods from being destroyed by logging. As the Chipko movement spread and captured public imagination and attention, it triggered regulations that restricted deforestation, safeguarding forests on the mountain slopes.

The Chipko movement inspired a generation of environmentalists in India and elsewhere. The peaceful resistance of Chipko, signifying the gentle, human act of hugging, signified a new environmentalism, an environmentalism of the poor rejecting overexploitation by industry, a renewal of people’s connections to land, reaffirming the human place in nature.

I come to a halt before an ash tree. I gaze at the grey-toned bark, at the rising ridges and falling furrows on the rough surface, at the trunk soaring up into a canopy flaming in evening light. Now, the soughing shiver of broadleaved trees, the sibilant whispers of conifers, and the incessant keening of mosquitoes become all too familiar. Now, too, the strange songs of vireo and chickadee and warbler are transmuted into known voices of yuhina and tit and flycatcher. Spruce becomes kail, cedar becomes divine deodar. Raven remains raven. Suddenly, I am struck by a sense of belonging, as if the ash and cedar are to me what the ash and deodar are to people in the Himalaya, the forest a space for solace, succour, and veneration.

Now, I am in India and it is the Vermont forest that has travelled around the world, and not me.

Madagascar essays

Two essays of mine based on field experiences in the island of Madagascar appeared recently. In these, I write about lemurs, tourism, conservation, and restoration of rainforests in the island. Here are a couple of teaser extracts and links to the essays.

Black and white ruffed lemur in Ranomafana

Black and white ruffed lemur in Ranomafana

From ‘Madagascar, Through the Looking Glass’ that appeared in EarthLines in March:

Where are the other trees in the countryside, he wonders? They see only a single palm tree during the drive and stop to photograph it. A few mango trees, Chinese guava, and that is all. Everything else is eucalyptus or wattle or pine. He feels something deep and significant is missing but cannot put his finger on it. Is it the absence of the great forests and other trees that were here once? The missing lemurs, even the giants, and the birds, like the elephant bird Aepyornis maximus – the mythical roc? Is it them? Were they even here, a millenium, two millenia ago? What was here then? He does not know. Does anybody know, he wonders. There appears no trace, no trace at all that he can see or sense, no memory of the past, of life before loss. He has never before seen an entire landscape that has lost its memory.

Indri in the forests of Andasibe

Indri in the forests of Andasibe

From ‘The Call of the Indri’ appearing in this month’s issue of Fountain Ink:

The smallest primate in the world is a lemur. At 30 grams, Madame Berthe’s mouse lemur is just a tad heavier than a sparrow. Imagine a miniature tennis ball, covered in a soft pelt of brown and cinnamon and creamy white, which has sprouted delicate limbs and clasping hands, a long furry tail, and a little head that turns to look at you through large, lustrous eyes. Like all other lemurs—including the iconic ring-tailed lemur, the aye-aye and sifakas, dwarf lemurs and sportive lemurs—this lemur’s natural range is confined within the island of Madagascar. The largest living lemur in Madagascar is the indri. At seven kilograms, the indri weighs as much as a healthy, six-month-old human infant. But instead of a crawling or bawling child, imagine a wild primate, dressed in striking black-and-white, capable of prodigious leaps from tree to tree and endowed with an incredibly loud and mesmerising singing voice.

In October 2012, one month before our visit to Madagascar, Madame Berthe’s mouse lemur and the indri, along with four other lemur species, were listed among the world’s 25 most endangered primate species. … All lemurs larger than the indri are already extinct.

Integrating ecology and economy: five lessons

“One of the hardest things in politics,” US President Barack Obama said in a recent interview, “is getting a democracy to deal with something now where the payoff is long term or the price of inaction is decades away.” Obama’s words are pertinent not only to the rules proposed on June 2 by his administration to cut future carbon emissions by US fossil-fuel power plants as a step to address climate change. They are also relevant to the other great democracy and its spanking new government on the other side of the planet: India.

The science whose central concern is the long term and leaving a healthy environment for future generations is ecology. And within ecology, on a planetary scale, it is the science of climate change. So when India’s new government, under Prime Minister Narendra Modi, renamed the Ministry of Environment and Forests (MoEF) appending ‘and Climate Change’, it was a timely move. It signalled that even as the government pursues its stated policy of industrial and infrastructural expansion for economic growth, it would place tackling climate change firmly on its agenda, along with the protection of environment, forests, and wildlife.

But a slew of media reports belie this interpretation. According to these reports, the MoEF, in its new avatar, plans to redefine what an inviolate forest is so that more forests can be opened for mining. It proposes to dilute environmental norms and procedures to bypass existing legal requirements for large infrastructure and defence projects. The government announced plans to increase the height of the Sardar Sarovar dam, raising concerns over the rehabilitation of 250,000 people, even as a ‘leaked’ Intelligence Bureau report attacked civil society NGOs for working on ‘people-centric’ issues. Meanwhile, the MoEF has been silent on other pressing needs: releasing the long overdue India State of Forest Report 2013, acting to save critically endangered species such as the Great Indian Bustard (now down to less than 300 individual birds in the wild), or implementing pro-active measures to combat climate change. Within hours of taking charge as Minister of State for Environment, Forests and Climate Change, Prakash Javadekar said with unsettling brevity in a TV interview: “… India needs a window for growth and emissions and other things.” To his credit, Mr Javadekar has promised to ensure that environmental protection and developmental activities will go together. While it is too early to assess promise against practice, this is as good a time as any to recount five lessons from ecology on why environmental protection should concern India’s new government and 1.2 billion plus people.

Thinking long term

Obama’s words point to lesson one: ecology takes the long view. Development projects promoted for short-term gains may have unaccounted long-term costs for people and nation. The previous United Progressive Alliance (UPA) government in its 10-year tenure allowed the conversion or loss of over 700,000 hectares of forest—an area the size of Sikkim—for development projects and non-forest uses. Natural forests of diverse native tree species function as watersheds, wildlife habitats, and sources of livelihood for tribal, farming, and fishing communities, contributing to long term human well-being in ways not captured by indices such as annual GDP growth.

The science of restoration ecology attests that such diverse natural forests and the living soils they spring from, once destroyed are difficult and costly, or infeasible to bring back, and appreciable recovery may still take decades to centuries. This is not adequately factored into the estimation of net present value (NPV) of forests that tries to approximate economic losses over a 20-year period, by which time the losses are ‘recovered’ in compensatory afforestation sites. A project developer pays out the NPV—at current rates, a maximum of Rs 10.43 lakhs per hectare for very dense forests in the most biologically rich regions such as the Western Ghats—and flattens football fields of forests for the price of a mid-range SUV. Furthermore, compensatory afforestation, if carried out at all, frequently involves raising plantations of one or few alien tree species such as eucalypts and wattles. Such artificial forests are no substitute for the more diverse natural forests of mixed native species, including centuries-old trees. This is why, as the Modi government worries over its 100-day report card, ecologists will be concerned about its 100-year fallout.

Minding the connections

Lesson two is that ecology is a science of connections, of food chains from plankton and fish to sharks and men, of energy flowing from sun through grass to deer and tiger. Pluck the hornbills out of their forest home and forest trees whose seeds the birds disperse begin to decline. Destroy forest remnants amidst coffee plantations and farmers suffer as coffee yields dip due to the loss of pollinating bees. Strip the oceans of sharks and predatory fish with industrial fishing and entire ecosystems and livelihoods of artisanal fishers unravel in what ecologists call a trophic cascade. So, the wholesale construction of 300 large dams in the Himalaya as proposed by the government would not just generate power, but have other negative consequences radiating down the chains and webs of life, including to people downstream. When these are taken into account, implementing fewer and smaller projects or alternatives appears more attractive.

The third lesson, the mandala of ecology, is that ecology closes the loop. Nature recycles, without externalities, wasting little. If the government applied this to everything from recycling municipal waste to curtailing pollution by industries, it could generate jobs and induce growth without leaving behind irredeemable wastes. Ecology is replete with such cycles. One sees it in the organic farmer practicing rotational shifting agriculture on the hillslopes of north-east India, in the cycle of water from earth to cloud to rain and river, and in the dung beetles and fungi and vultures that help return dung and vegetation and carrion to the elements.

Fourth, ecological processes transcend political boundaries. We pump CO2 and other greenhouse gases into the common pool of our atmosphere anywhere and affect people and the earth’s fabric of life everywhere. The migratory warbler that picks the insects off the plants in our gardens may depend for its survival on protection of its breeding grounds in China or Central Asia. To conserve tigers and elephants in protected reserves, we need to retain connecting corridors and forests, some spanning state or international boundaries. Development and infrastructure projects can be designed and implemented such that they do not further disrupt fragmented landcapes, but instead help retain remnant forests or reconnect vital linkages.

On the road to development?  Destructive project promoted for short-term gains may have unaccounted long-term costs to people and nation.

The science of home

Finally, ecology teaches us that humans are not external to nature. Land and nature are not commodities to buy or sell recklessly or reduce to a packaged spectacle for tourists to gawk at. They form the community we belong to: we are part of nature, it is home. In the debate over ecology versus economy, we must remind ourselves that both words originate from the Greek word oikos, meaning home. The science of our home environment (ecology) must inform the management of our home resources (economy).

What is often forgotten, in the debate falsely caricatured as environment versus development, is that for almost every destructive project, there are often alternatives and means of implementation that cause less harm to environment and local communities, and can provide overall long-term benefits. For instance, roads can be routed to avoid wildlife sanctuaries and provide better connection to peripheral villages, thus helping both people and wildlife. Decentralised village power generation systems that use biomass, solar power, and other renewable sources can help reduce reliance on mega power projects plagued by corruption and requiring long powerlines that suffer transmission losses and cause forest fragmentation. Mining can be carried out avoiding areas valuable for conservation or local people, after due environment and forest clearances, and keeping aside topsoil to ecologically restore even these areas later.

There are already many promising examples of ecologically sensitive development. If ecologists, engineers, and economists synergise their efforts, and the government chooses to exercise its electoral mandate to take the long view, there can be many more. The integration of ecological considerations into economic development is vital and valuable if, in the pursuit of profit, we are to ensure the long-term well-being of people and planet.

The enduring relevance of Rachel Carson

It is tough for a single publication or its author to have an impact across nations, cultures, genres, and disciplines. It is tougher still for their appearance on the world stage to spark a social movement, rekindle human values and awareness, and create new mandates for action. And toughest of all is when the author is a woman, a scientist, who must overcome the prejudices of her time−of gender, of notions of progress, of the omnipotence of untrammelled industry−to articulate a clear-eyed, renewed vision of a better world, a cleaner environment, where people do not merely live, but flourish.

If I had to pick one exemplary work from the environmental canon that does this and does it well, it would be the one that burst on the scene on this day, 16 June, all of 52 years ago, in the United States of America and then swiftly encompassed, in its scope and sweep, the rest of the world. The book, Silent Spring, and its author, marine biologist Rachel Carson, are widely credited to be the sparks that lit the fire of the global environmental movement. Carson, whose 107th birth anniversary came and passed quietly on May 27, with little fanfare other than a commemorative Google Doodle, died fifty years ago after a battle with breast cancer. Why should we bother to remember Rachel Carson and Silent Spring? What could a woman, a book, from over five decades ago have to do with the enormously changed world we live in today? Yet, over the last few weeks, during fieldwork and travels in India’s northeast and the Western Ghats mountains, I thought frequently of Rachel Carson and her prescient words in Silent Spring.

27 February 2014, Chawrpialtlang peak, Dampa Tiger Reserve, Mizoram. Slicing through the air over crackling-dry grass on the peak, a black-tipped arrow streaks past, plunges down the sheer cliffs, swerves around the mountain, and is gone. For one rushing moment, the ripped air appears to shimmer, as if in sudden clarity, then closes in the fleeting wake of the bird. A Peregrine Falcon. Windswept and breathless, I stand on the peak and think of Rachel Carson. For it was in Silent Spring that she described and I learned how the chemical pesticide, DDT, sprayed or dusted into the environment, entered water and soil and animal tissue as a persistent organic pollutant, and travelled up the food chain, accumulating from pest to predator to top predator, into birds like Peregrine Falcons and Bald Eagles, thinning their egg shells, making the brood crumble instead of hatch in the nest, bringing down populations, endangering the species itself. Only when awareness of this issue soared after the publication of Silent Spring and concerted efforts including a DDT ban were made did raptor populations recover, so that the birds could wing and scythe through the air again.

20 March 2014, Mamit District, Mizoram. On the outer wall of bamboo hut after hut, in village after village, in one of the most remote and malaria-prone corners of India, I see inscribed in chalk: “DDT 15/03/14“. The date varied a little from village to village, but it took me only a moment to realise that this was just a marker that each of those huts, the homes of Mizo and Riang tribal peoples of the state, had just been sprayed with DDT. And DDT is the one chemical for which Rachel Carson’s work is most known for and most frequently and unjustly vilified. Carson, using a growing body of research, highlighted the environmental and human health consequences of excessive DDT use in Silent Spring. The book along with the growing tide of awareness led ultimately to a ban on DDT and consequently, or so the accusation goes, it became unavailable for use in malaria control and led to the death of millions. In reality, DDT was banned for use only in agriculture and unrestricted aerial spraying, while it is readily available and continues to be used for malaria control across the world. And here was evidence, decades later in Mizoram, that this accusation is untrue: DDT continues to be used for malaria control as a public health measure. In Mizoram, as in other states in India, the government has an Indoor Residual Spray (IRS) programme of DDT, usually twice a year, coupled with distribution of deltamethrin insecticide-impregnated mosquito nets. DDT was banned for agricultural use in India in 1989, but even this was not a complete ban, as it carried a rider allowing the use of DDT under ‘very special circumstances’ for plant protection from pests, under the supervision of the State or Central government. In 2006, an Indian government order permitted the use of up to 10,000 tons of DDT annually for public health and vector control measures. In Mizoram, where I knew malaria was still frequent (it knocked me down for two weeks during my fieldwork here in 1994), there were more pertinent issues than these false debates and vilification of Rachel Carson. Loss of effectiveness of DDT due to overuse and dependence on the chemical, the need for better public healthcare facilities, and the fact that more than 90% of the local people prefer insecticide-impregnated mosquito nets over indoor DDT sprays, all seem more important issues to be discussing.

23 May 2014, coffee and tea estates near Sakleshpur, Western Ghats. As our car speeds past the gate of the coffee estate, I cannot help recalling the troubling moment inside in 2011, while doing a diagnostic audit for a company that was planning to go for Rainforest Alliance certification of their coffee production. There, beside a small pond, a group of workers had been preparing a pesticide concoction for spraying on the coffee bushes. In the group, helping mix and spray the chemical on coffee bushes, without any protective equipment to cover her face or exposed hands, was a 12-year-old girl. Even as the child was exposed to the chemical, the pesticide tub overflowed and spilled into the pond. Decades after Silent Spring, after knowing the effects of pesticide pollution on the natural environment and learning more and more about how pesticide exposure affects human health, it is a pity that in many of our plantations and agricultural fields, so little is done to reduce or prevent pollution, to minimise or avoid exposure to agrochemicals.

Later, in a tea estate, I listen to a manager describe how their chemical sprays had failed to control a pest, the red spider mite, because, he said, the chemical sprays killed the natural predators of the mite such as ladybird beetles. Again, I recall how in Silent Spring Rachel Carson had explained how insecticides had the counterproductive effect of increasing spider mite infestation: by not affecting them directly, by killing instead mite predators like ‘ladybugs’, and by scattering mite colonies that now focused on increasing their reproductive output as they had no need to invest in defence against predators because the people with the chemicals were inadvertently doing this job on behalf of the mites. I suggest to the manager, like Carson did to her readers, that perhaps the best way ahead is to change cultivation practices, foster more biological diversity in the farm landscape, and reduce their reliance on agrochemicals. He nods, but I am not sure he is ready, as yet, to agree.

26 May 2014, Highway to Valparai, Anamalai hills. All along the highway, the vegetation on the sides of the road lie slashed. Beautiful ferns, orchids, wild balsams, and a number of wildflowers that added grace and beauty to the road, now lay withering on the tarmac, crushed under the spinning wheels of speeding vehicles. The Highways Department had been ‘cleaning’ the roadside again and scraping the soil, leaving brown strips beside grey tarmac and concrete. Soon, the exposed earth would be taken up by invasive alien weeds, changing the roadside aesthetic from the lush green of small native plants and wildflowers to dour greys and browns and weeds. Seeing this, Rachel Carson’s words in Silent Spring again came to mind, for she wrote also about the beauty of wildflowers along the roads, criticizing “the disfigurement of once beautiful roadsides by chemical sprays” and “the senseless destruction that is going on in the name of roadside brush control throughout the nation.”

Whether it was wildfowl or wildflowers, Rachel Carson’s insistence in Silent Spring that scientific understanding of the environment should integrate ethical and aesthetic values struck a chord with readers. The book did not merely inform them, it affected them, and spurred them to act, thus catalysing the birth of a movement.

* * * * *

The environmental movement, as philosopher Arne Naess once remarked, was one of the three great movements that marked the twentieth century; the others being the movements for world peace and social justice. Among the three, the ecological or environmental movement is relatively nascent. One can trace roots of environmentalism, at least in its modern form, to early concerns over nature conservation and vanishing species, but it was really in the latter half of the last century that the movement really took off.

In the aftermath of World War II, with the development and testing of atomic weapons, concerns over the perils of nuclear war and radioactive fallout was widespread. Still, there remained unbridled optimism over the promise of new and powerful technologies in the post-war industrial world. At the same time, rising pollution of air and water following industrialisation and consequent effects on human health spurred early efforts to curb pollution beginning in the 1950s, culminating in laws enacted over the ensuing years and decades in various countries. In the 1960s, the great phase of dam-building was also in full steam. As the environmental historian J. R. McNeill recounts, on average one dam was built per day around the world during that decade. Construction of dams and the displacement of thousands of people by reservoirs was also bringing growing awareness of the alteration of entire landscapes by human action, and about harmful impacts on the environment and livelihoods of people living in the catchment area and downstream.

Still, this was a period when the industrial juggernaut rolled on, backed by a specific vision of development based on technology and large, so-called infrastructure projects. It was a period, in India and elsewhere, when impacts on environment or the lives, lands, and livelihoods of local peoples could be brushed aside on the basis of a grandiose, little-questioned development trajectory. Besides, India and other countries stood at the cusp of a major transformation of agriculture into intensive cultivation dependent on a slew of chemical fertilizers and pesticides: the Green Revolution.

It is in this context that one must view the publication of Silent Spring, first serialised in The New Yorker magazine beginning on 16 June 1962, and then published as a book by Houghton Mifflin on September 27 of that year. The book burst on the scene with a telling and convincing account, based on scientific evidence, of the perils that the chemicals used as pesticides and fertilizers brought to human health and the environment. Carson, a skilled writer, explained in clear but compelling detail the various kinds of chemical poisons used in agriculture and pest control, such as DDT, chlordane, and lindane, organophosphates, and carbamates. With care and clarity, she collated research findings published in scientific papers and recorded personal experiences of people around the US, and described the effects of the chemicals on human health, their persistence in the environment, and build-up (bio-accumulation) over time in the bodies of people and wildlife. She explained concepts such as how pests developed resistance to the chemicals, how that ultimately led to resurgence of pests, and to a vicious cycle of more potent poisons being created.

As Carson wrote,

The current vogue for poisons has failed utterly to take into account these most fundamental considerations. As crude a weapon as the cave man’s club, the chemical barrage has been hurled against the fabric of life—a fabric on the one hand delicate and destructible, on the other miraculously tough and resilient, and capable of striking back in unexpected ways.

By ignoring ecology, the agro-chemical industry appeared poised to fail in finding long-term solutions. Carson did not stop with careful explanation and evocative descriptions of the problem of increasing dependence on chemicals. She went further and described a way forward to sustain productive agriculture without recourse to the ‘chemical barrage’. In her words:

A truly extraordinary variety of alternatives to the chemical control of insects is available…. All have this in common: they are biological solutions, based on an understanding of the living organisms they seek to control, and of the whole fabric of life to which these organisms belong. Specialists representing various areas of the vast field of biology are already contributing—entomologists, pathologists, geneticists, physiologists, biochemists, ecologists—all pouring their knowledge and their creative aspirations into the formation of a new science of biotic controls.

There were several reasons why Silent Spring was so effective upon its publication. Carson drew upon her earlier experience as a biologist with the US Fish and Wildlife Service where she served as an editor in the Division of Information, reading scientific publications and transmuting them into readable and informative articles for citizens. Today, she would be called a leading science communicator in biology and the environmental sciences. What was remarkable about her writing was that even as she explained science to the citizen, she did not flinch from simultaneously interlacing into her writing moral values and the ethical consequences of environmental harm, which she was convinced was equally significant to her readers.

Why should we tolerate a diet of weak poisons, a home in insipid surroundings, a circle of acquaintances who are not quite our enemies, the noise of motors with just enough relief to prevent insanity? Who would want to live in a world which is just not quite fatal?’

Carson was a dedicated writer. She had always wanted to be a writer since her early childhood. When she joined the Pennsylvania College for Women (later Chatham College) in 1925 as an 18-year old, she enrolled for an English major, until a biology course in her junior year reawakened her “sense of wonder” for nature, another fascination since childhood. Later, she obtained her Master’s degree in zoology from Johns Hopkins University, Baltimore, following which she taught zoology in Maryland and worked at the famous Woods Hole Marine Biological Laboratory, Massachusetts. Her biological knowledge as a trained scientist, her field experience as a naturalist and keen observer of nature, and her literary talent came together as a potent combination in her books.

Although Rachel Carson is perhaps most known for Silent Spring, she wrote other books including a trilogy on the sea and marine life, a book for children titled The Sense of Wonder, and a number of magazine articles. Of the three books in the sea trilogy, Under the Sea-Wind, The Sea Around Us, and The Edge of the Sea, Carson won the National Book Award in 1952 for The Sea Around Us. That book remained on the New York Times best sellers list for 86 weeks.

The success of Carson’s books such as The Sea Around Us and Silent Spring was at least partly due to the way Carson managed to meld scholarship and literary talent. As Carson said in her acceptance speech for the National Book Award:

The aim of science is to discover and illuminate truth. And that, I take it, is the aim of literature, whether biography or history or fiction. It seems to me, then, that there can be no separate literature of science.

… If there is poetry in my book about the sea, it is not because I deliberately put it there, but because no one could write truthfully about the sea and leave out the poetry.

Still, there was more to Silent Spring than just scientific rectitude or literary flair. Carson recorded and used in the book many case studies and personal experiences of people who had witnessed the effects of aerial spraying and pesticide overuse. The Silent Spring metaphor itself, referring to a spring that goes silent as songbirds decline and disappear due to pesticide use, was inspired by a letter from a friend who noted dead birds lying around her house after an aerial pesticide spraying bout in her area, and who now wanted the spraying to stop. Taken as a synecdoche, it suggested that people were sensitive to environmental destruction and it had reached a point where they had had enough.

Silent Spring and its author were (as one would expect even today) attacked by Government agricultural scientists and companies with high stakes in the agrochemical industry such as Velsicol, a major manufacturer of DDT, and Monsanto. Velsicol threatened to sue the the publisher Houghton Mifflin and The New Yorker. Detractors and vested interests made personal attacks on Carson, asking why “a spinster was so worried by genetics”, and disparaged her as hysterical, emotional, unfair, one-sided, and as given to inaccurate outbursts. But, ultimately, the science behind Silent Spring withstood public scrutiny, including a congressional hearing, the author herself stood calm and dignified with her research, credentials, and explications, and the book, instead of being pulped as her opponents may have wished, went on to become a bestseller, sell millions of copies, and make history. The reactions and desire for change that the book triggered influenced environmental legislation and policies worldwide. The years that followed the book’s publication saw the first Earth Day celebration and the formation of US Environment Protection Agency in 1970, the gathering of representatives from 113 countries at the United Nations Conference on the Human Environment at Stockholm in 1972, the enforcement of a ban on DDT in 1972, and other efforts around the world overtly inspired or tangentially influenced by Silent Spring. In that period, India, too, made several legislative and policy efforts, as the country enacted the Insecticide Act in 1973, laws to prevent water and air pollution and protect forests and wildlife in the 1970s and 1980s, and the Environment Protection Act in 1980 that also created the State and Central Pollution Control Boards and other authorities with environmental mandates.

The appearance of Silent Spring was one of the defining moments in the history of environmentalism, one that would irrevocably shake the complacency and complicity of state and industry in environmental harm. Today, one may quibble over the details of Silent Spring, over what the author chose to write about, or over how she wrote about it. But what one must acknowledge is that much of what Rachel Carson wrote about and the scientific and moral clarity she brought to it remains relevant over five decades later. From Maryland to Mizoram, then as now, the problems she described and the solutions she offered remain valid, apposite, and vital. In that respect, Rachel Carson and Silent Spring remain of enduring relevance.

Mizoram: bamboozled by land use policy

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).

Labelling jhum as unproductive and destructive of forest cover, policy makers and industry now promote “settled” cultivation and plantations, such as pineapple and oil palm, claiming they are better land use than jhum. However, oil palm, rubber, and horticultural plantations are monocultures that cause permanent deforestation, a fact that the 2011 India State of Forest Report notes to explain recent declines in Mizoram’s forest cover. In contrast, jhum is a diversified cropping system that causes only temporary loss of small forest patches followed by forest recovery. Understanding this is crucial to formulate land use policy that is economically, ecologically, and culturally appropriate for Mizoram and other northeastern hill states and their tribal communities who live amidst extraordinarily rich forests.

Organic jhum

Jhum uses natural cycles of forest regeneration to grow diverse crops without using chemical pesticides or fertilizers. Early in the year, farmers cut carefully demarcated patches of bamboo forests and let the vegetation sun-dry for weeks. They then burn the slash in spectacular but contained fires in March to clear the fields, nourish soils with ashes, and cultivate through the monsoon. In small fields, one to three hectares in area, each farmer plants and sequentially harvests between 15 and 25 crops—indigenous rice varieties, maize, vegetables and herbs, chillis, bananas, tubers, and other species—besides obtaining edible mushrooms, fruits, and bamboo shoots. After cultivation, they rest their fields and shift to new areas each year. The rested fields rapidly regenerate into forests, including over 10,000 bamboo culms per hectare in five years. After dense forests reappear on the original site, farmers return for cultivation, usually after six to ten years, which forms the jhum cycle.

Regenerating fields and forests in the jhum landscape provide resources for many years. The farmer obtains firewood, charcoal, wild vegetables and fruits, wood and bamboo for house construction and other home needs. The diversity of food and cash crops cultivated and ancillary resources provided by current and rested jhum fields complicate comparisons with terrace or monocrop agricultural systems. One-dimensional comparisons—such as of rice yield per hectare or annual monetary return—can be misleading, because one needs to assess the full range of resources from jhum field, fallow, and forest, over a full cultivation cycle, besides food security implications.

Comparing monocrops like pineapple or wet rice paddies cultivated using chemical inputs with organic jhum is not just comparing apples with oranges. It is like comparing a pile of pineapples with a basket containing rice, vegetables, cash crops, firewood, bamboo, and more. Inter-disciplinary, holistic studies, notably those led by Prof. P. S. Ramakrishnan of Jawaharlal Nehru University, New Delhi, indicate that at cycles of 10 years or more jhum is, in his words, “economically productive and ecologically sustainable”.

Soon after the field is burnt, the first rains appear, and fields become quickly covered in green.

Bamboo landscapes

In Mizoram, bamboos coexist with jhum in a dependent cycle that is often overlooked: where we only see jhum fires burning forests, we fail to see forests and bamboo regenerating rapidly after a season of cultivation. The 2011 India State of Forest Report estimated that bamboo bearing areas occupy 9245 square kilometres or 44% of Mizoram. For every hectare of forest cleared for jhum, farmers retain 5 to 10 hectares as regenerating fallow and forest in the landscape. Also, forests left uncut by jhum farmers along ridges, ravines, and other areas, contain bamboo species. Besides Mautak (Melocanna baccifera) that dominates in regenerating forests, over two dozen native bamboo species occur naturally in Mizoram’s forests and jhum landscapes.

Yet, government policy tilts firmly against jhum. The State’s New Land Use Policy (NLUP) deploys over Rs 2800 crores over a 5-year period “to put an end to wasteful shifting cultivation” and replace it with “permanent and stable trades”. Under this policy, the State provides Rs 100,000 in a year directly to households, aiming to shift beneficiaries into alternative occupations like horticulture, livestock-rearing, or settled cultivation. The policy has created opportunities where little existed earlier for families seeking to diversify or enhance income, for farmers whose harvest is insufficient to meet year-round needs, and for skilled and urbanising workers seeking other jobs and trades. Still, NLUP’s primary objective to eradicate “wasteful” shifting cultivation appears misdirected.

Even before NLUP was implemented, despite decades of extensive shifting cultivation, over 90% of Mizoram’s land area was under forest cover, much of it bamboo forests resulting from jhum. Recent declines in forest cover have occurred during a period when area under jhum cultivation is actually declining, while area under settled cultivation is increasing, suggesting that the land use policy has been counterproductive for forests.

Certainly, some areas may need protection from jhum. My earlier research indicated that remnant mature evergreen tree forests, as in the core of Dampa Tiger Reserve in western Mizoram, need to be protected for specialised and endemic rainforest species. But as forests regenerating after jhum support diverse plant and animal species, I had suggested fostering jhum in areas such as the buffer zone landscape surrounding the Reserve. From perspectives of agroecology, biodiversity conservation, and human – wildlife coexistence, jhum is far preferable to monoculture plantations such as teak and oil palm that now increasingly abut the Reserve.

Oil palm and forest loss

Oil palm, notorious for extensive deforestation in south-east Asia, is cultivated as monoculture plantations devoid of tree or bamboo cover, and drastically reduces rainforest plant and animal diversity. In Mizoram, 101,000 hectares have been identified for oil palm cultivation. Following the entry of three corporate oil palm companies, over 17,500 hectares have already been permanently deforested within a decade. Promoting and subsidising such plantations and corporate business interests, undermines both premise and purpose of present land use policies. As forest cover and bamboo decline, people in some villages now resort to buying bamboo, once abundant and freely available in the jhum landscape. If present trends continue, Mizoram is likely to be bamboozled out of its forest cover and bamboos.

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).

Detractors of jhum often concede that jhum was viable in the past, but claim population growth has forced jhum cycles to under five years, allowing insufficient time for forest regrowth, thereby making jhum unsustainable. Reduction of jhum cycle is serious, but evidence linking it to population pressure is scarce. As Daman Singh notes in her book, The Last Frontier: People and Forests in Mizoram, villagers actively choose to cultivate at 5 – 10 year cycles even when longer periods are possible. In reality, jhum cycles often decline because of external pressures, relocation and grouping of villages, or reduced land availability. Village lands once open to local people for jhum are now fenced off under government or private plantations and horticulture crops often belonging to people who are wealthier or live in distant urban centres. But none of this implies jhum itself is unsustainable.

The science and sustainability of jhum is reviewed in a 2012 paper titled ‘Shifting cultivation in steeply sloped regions: a review of management options and research priorities for Mizoram state, Northeast India‘ published in the journal Agroforestry Systems. In it, the authors, Dr Paul Grogan of Queen’s University, Canada, and Drs F. Lalnunmawia and S. K. Tripathi of University of Mizoram, Aizawl, state: “… in contrast to many policy-makers, shifting cultivation is now considered a highly ecologically and economically efficient agricultural practice provided that [authors’ emphasis] the fallow period is sufficiently long.” The authors list options to enhance shifting cultivation, such as nutrient and water supplementation, optimising crop choice to extend site use period along with measures to further retain soil and fertility, and judicious use of commercial fertilizer coupled with organic inputs.

Clearly then, attempting to eradicate and replace shifting cultivation, as NLUP does, is inappropriate. Instead, a better use of public money and resources would be to work with cultivators and agroecologists to refine jhum where needed. The State can involve and incentivise communities to foster practices that lengthen cropping and fallow periods, develop village infrastructure and access paths to distant fields, and provide market and price support, and other benefits including organic labelling to jhum cultivators. Today, the State only supports industry and alternative occupations, leaving both bamboo forests and farmers who wish to continue with jhum in the lurch. Unless a more enlightened government reforms future policies in favour of shifting agriculture, Mizoram’s natural bounty of bamboos is at risk of being frittered away.
