Book Review: Environmental Issues in India

The Varying Shades Of Green

Business World, September 2007

Most people including conservationists think that when a species is in trouble, all it requires is a chunk of protected forest. However, in a high population density India, there are several other constituents or stakeholders involved — local people utilise the forest to graze their cattle and/or collect plant material for a living. How to deal with these people has split the conservation community in two. While one group argues for their relocation out of the forest, the other advocates giving them rights to the forest.

Arun Agrawal and Vasant Saberwal, for example, argue that “cultural sensibilities have combined with an overarching concern with human impacts on the environment, to generate conservation rhetoric on the need to keep people and livestock out of protected areas”. A few chapters later, Ullas Karanth cautions against confusing conservation issues with livelihood issues and concludes “sacrificing the remaining 3 per cent or so area under wildlife reserves is unlikely to make any dent on human problems, which we have been unable to solve by using and abusing the remaining 97 per cent of the land area”.

The relocation lobby tacitly backs the third main constituent, the forest department whose mandate is to conserve these forests despite obvious mismanagement, while the other side views it as an adversary that denies people their traditional rights while selling out to Big Industry. Who is the better guardian of the forest has become the fundamental question fissuring the conservation community.

Understanding the political tangle that includes the aspirations of local people, the limitations of the forest department and the need for landscape conservation, can reduce the increasing polarisation within the Indian conservation community. This is precisely what this reader offers. The anthology of 33 essays is a first for India and promises to be an indispensable tool for anyone interested in Indian conservation and environmental movements. The book spans timelines and histories of various regions, peoples and struggles. India is a microcosm of dilemmas facing much of the developing world that seeks to balance the survival needs of people and wildlife.

Much blame for the precipitous status of several species of animals is heaped on the doorstep of the British Raj. Citing archaeological evidence, Mahesh Rangarajan, editor of the volume, records the collapse of species well before colonial times. For example, over-hunting and habitat loss exterminated the barasingha from Baluchistan by 300 BCE. Several species of plants found in western Indian sites are now extinct. Indians weren’t the traditional paragons of conservation as some romantics will have us believe.

Had we followed the Gandhian model of rural economy would we have avoided the state we find ourselves in? In an incisive essay, Ramachandra Guha evaluates whether Gandhi was the patron saint and Nehru the villain of the environmental movement. The author reminds us that the majority of Indians rejected Gandhi’s model of rural economy. Whereas Nehru, the romantic who “was deeply appreciative of the natural beauty of India”, as the democratically elected representative of the people, acted on the “overwhelming consensus” for rapid industrialisation. However, one of Gandhi’s disciples, Mira Behn was environmentally proactive; nearly 60 years ago she sent Nehru a critique of the forest management policy accompanied by pictures in which she identified the lack of involvement of villagers and the monoculture of pine. To this day, we continue to debate these issues.

Modern global environmental concerns such as nuclear energy and climate change also find a place in this volume. In recent years there have been controversial claims promoting nuclear energy as the new “green energy”. True, it is a low polluting source of energy unlike coal. However, Eliot Marshal puts the cost of going nuclear in perspective: a Natural Resources Defenses Council physicist is quoted as saying that to avoid a 0.2 degree Celsius rise in global temperature at the end of the century, the world would need to build “1,200 new plants in all, at a rate of about 17 per year”. Then there are the attendant concerns over safety hazards, nuclear waste disposal and the misuse of reprocessed plutonium. The book doesn’t offer easy answers, but to present these different perspectives in a single volume is a major first step.

However, there are numerous typographic errors; the punctuation is random. And references mentioned in the text are not in the list at the end. Dates quoted for publications within the text differ from the references at the end. Authors’ names are misspelt. These are irritations that an international publisher of such stature could have easily fixed. Despite these drawbacks, the book is a real steal for the price.

The Song of the Ganges Gharial

Published Seminar 577, September 2007

Circa 1996: The impossible had been achieved. The gharial, which had been on a rapid slide to extinction, had been pulled back. Conservationists slapped each other’s backs. In those dismal days when the future of the tiger in India was thrown in doubt and the premier conservation undertaking for its benefit, Project Tiger, was exposed for its hollow claims, Project Crocodile was touted as being one of the most successful conservation efforts in the world. The morale of Indian conservationists received a rare boost while they struggled to fight a seemingly graver battle for the tiger.

The last of an ancient lineage
The gharial is the only true descendant of an ancient family of crocodiles that lived on earth 100 million years ago. A fossil of a sea-faring gharial, recently unearthed in Puerto Rico, was dated to at least 23 million years ago while another giant, a 15 metre long gharial, was excavated from Niger in the 1990s. After the last Ice Age, the gharial staked out about 20,000 square kilometres of rivers, spanning Pakistan to Myanmar, as its territory. Not for the gharial the still waters of ponds or lakes where other crocodilians thrive. This is a true specialist: a river-dweller that eats only fish. Unfortunately, the gharial’s narrow choice of habitat and diet inevitably led to its downfall.

The beginning of conservation action
It all began in 1970 when a disturbing report by the biologist, S.Biswas said that the gharial had simply vanished from the Kosi River and recommended that the other rivers be surveyed. In 1973, conferring with Bombay Natural History Society’s scientists and funded by Worldwide Fund for Nature (WWF), a team from the Madras Snake Park did extensive surveys across every major river and stream throughout the gharial’s range in India and Nepal – the only two countries in the world that are now home to the reptile. By this time the gharial had been declared extinct in Pakistan, Myanmar and Bangladesh. Although Bhutan was also a gharial country, its mountainous terrain limits its range to a few stretches of river close to the India border. The headcount came to only 200 gharial; the population had crashed by about 98% in 30 years.

Something radical had to be done and in 1975 the Government of India set up Project Crocodile with the support of the United Nation Development Fund’s (UNDP) Food and Agriculture Organization (FAO). With alarm bells ringing in its ears, Project Crocodile went to work for the benefit of the three endangered Indian crocodilians – the mugger, the salt-water crocodile and the gharial. It delineated 20,000 square kilometres as sanctuaries and set up several captive rearing projects. Of these the gharial occupied six sanctuaries spread over 240 square kilometres while 16 captive rearing centres were to act as its wet nurses. Although the initial project proposal included concessions such as croc farming as an alternate livelihood for fishermen who would be affected by the conservation measures, it was not implemented and the gharial was soon to pay the price for this oversight. However, those were heady days and such “minor” blips did not dampen the spirits of croc conservationists who strongly believed they could turn the tide.

A training centre (later to become the Wildlife Institute of India) for crocodile biologists was set up in Hyderabad and several Ph.D students were recruited, who were to become the frontline field workers for the gharial. Besides declaring sanctuaries and fostering research, a captive breeding program was initiated as well. But India didn’t have a captive male, and in fact there were only an estimated 10 to 20 adult males in the world at that time. The Frankfurt Zoo in Germany had the only captive male which was donated to the project. To kick-start the program some eggs were even bought from Nepal during the first year. One of the primary thrusts of the conservation plan was to rear hatchlings from eggs (collected both from the wild and captivity) for 3 to 4 years until they reached the length of 1.2 metres (4 feet) before releasing them in the rivers. The idea of “head-starting” was to provide hatchlings the safety of enclosed concrete ponds guarded from predators during the most vulnerable period of their lives. In the following 30 years, 12,000 eggs were collected and over 5000 such head-started gharial were returned to the wild in five sanctuaries. Since the Chambal River is the last “wild” river in North India, it held all the hopes for the future of gharial – even today it holds 48% of the population. And this is where Project Crocodile focused its attention by releasing 3500 animals here alone. Gharial numbers surged in the subsequent years and the picture looked rosy. And then the rug was yanked from beneath.

Unwitting wardens of the Chambal
Uniquely for India, the National Chambal Sanctuary straddles 3 states – Uttar Pradesh, Madhya Pradesh and Rajasthan – including some of the wildest areas that were out of bounds for the state machinery. The ravines on the banks of the river were the hideout of some dreaded bandits, the most infamous among them being Phoolan Devi, the Bandit Queen. These outlaws ruled the roost, making sure that the area remained untouched by the Government’s development plans. Nobody wanted to invest in any industry or buy real estate in these parts. Researchers and Forest Department personnel were vulnerable targets and they made sure they were not caught in the field after dark.

Phoolan Devi however, captured one croc researcher, Dhruvajyoti Basu, and snatched away his binoculars. When he pleaded saying they were not his and the Forest Department would give him much grief if he lost them, the bandit gave him a signed voucher declaring that she, Phoolan Devi, had “borrowed” the binoculars. He was then set free, unharmed. Others who faced the wrath of the outlaws were not so lucky. Ironically, the gharial (and the habitat) thrived under the unwitting but ruthless “protection” by the bandits.

Change of guard
In the mid-1990s in response to state offered amnesty, the brigands started to give themselves up one by one. The police were slow to fill the power vacuum thus created. Other anti-socials – local mafias – began setting up shop. While the outlaws had restricted themselves to fobbing off the rich, the mafia began to systematically exploit the resources – sand mining (to feed the building boom in cities like Delhi and Agra), fishing in the Sanctuary, turtle poaching and so on. One official, speaking off the record, said the large scale sand mining had brought down banditry in the region, thereby indirectly demonstrating that addressing the livelihood needs of the people is key to achieving conservation success! Poor villagers, struggling to make a living from agriculture, irrigated their fields with water siphoned off the river leaving the lower reaches of the river shallow in summer.

A District Collector who visited the place recently to put a stop to the illegal activities was beaten up and his police escorts were reduced to mute spectators. Although the National Chambal Wildlife Sanctuary is governed by three-states, there is limited enforcement of conservation agendas and people there do pretty much what they want. (Recently, however, the Forest Department sought permission to shoot illegal sand miners to enforce the law.)

Not to be outdone, the government water authorities such as the Irrigation Department built barrages, irrigation canals, artificial embankments and controlled other gharial rivers to an extreme degree – impounding the river during the lean summer months (when all the aquatic animals are imprisoned in a few deep pools), and opening the sluice gates in one go after the rains, causing a veritable tsunami (washing down everything caught in its powerful currents – uprooted trees, gharial, dolphins). All these activities impacted the gharial directly.

However, once gharial conservation was deemed a great success (when the population in the Chambal climbed to over 1200 between 1993 and 1997), the Government of India withdrew money from the expensive croc breeding and release program. No surveys were conducted between 1999 and 2003 but that didn’t worry too many people as the gharial had after all been saved. In 2004, croc conservationists were shocked when Dr. R.K. Sharma, a gharial biologist of the Madhya Pradesh Forest Department, alerted them to the news that the gharial numbers had nose-dived and there was visible degradation of the habitat.

Back on the brink
The last assessment in 2006 revealed that the gharial was in even more distress than 2003; there are no more than 200 wild breeding gharial in Nepal and India. This situation may seem marginally better than the dire straits the gharial found itself in the early 1970s but now the pressures on the habitat have multiplied and the quality of what remains is deteriorating. Besides, the future viability of the species is compromised because the 200 breeders are spatially separated. The massive influx of funds and the release of 5000 captive-reared gharial have not achieved any significant reversal. More barrages and dams are on their way for almost every river that is home to the gharial. The situation is even worse in the other range country: Nepal.

Today the gharial’s domain is a mere 2% of its former range, limited to a couple of hundred square kilometres and dwindling. The future of the gharial is so threatened that its Red List status was recently revised from Endangered to Critically Endangered, one stop away from Extinction. It is, today, the most endangered large animal in India, more gravely endangered than the tiger.

What went wrong?
Although a critical scientific assessment of past conservation achievements (including one that grades threats according to their severity) has not yet been done, the picture outlined here was arrived at by connecting survey numbers, field visits, and reports (by various workers). In hindsight, three shortfalls in the conservation program were identified – the habitat was never secured, local people were not taken on board; monitoring of the released juveniles was not done (all these “boring” issues were addressed in every set of recommendations dating from the 1970s, but were ignored in favour of the seductive simplicity of reintroductions) and the significant conservation headway (designation of croc sanctuaries, successful captive breeding, research, publicity and international support) that was made has slowly unravelled under the sustained onslaught of river resource exploitation. This resulted in widespread deterioration of gharial habitat (barrages, dams caused the rivers to silt up, sand mining on basking and nesting beaches), and depletion of prey by illegal fishermen. Several large adult gharial drown in fishing nets and get ensnared by hooks laid by turtle poachers every year. The few that are lucky enough to survive in the nets face a more horrible fate. Fishermen cut the long fragile snouts of the gharial tangled in their nets before setting them free. These handicapped gharial will slowly starve to death within a year. Tolerance is obviously on a short leash.

In India, conservation is generally driven by biologists with little or no inputs from social scientists. The exclusive (throwing fishermen out of the sanctuary and curtailing any human activity) and unsympathetic (no alternate livelihood options offered to the affected people who became destitute overnight) state conservation policies have replaced any existing traditional conservation values with bitterness and anger. The gharial has become the symbol of people’s alienation from their natural resources and there is no support for its continued existence.

The majority of the crocodile conservationists in India may believe that the gharial is again facing extinction because reintroduction efforts are down to a minimum. The reality is that the expensive “head-starting” programs may have achieved little. Since the released gharial were not monitored, no one knows how many survived. Out of the thousands released, only hundreds remain. We can only surmise that they did not have the wherewithal to deal with the strong currents (nor did they possess the muscle tone after being reared in still pools) and the absence of calm tributaries may have resulted in most of these young ones being flushed out of the sanctuaries into the inhospitable habitats downstream during the annual monsoon floods. It is also possible that these captive reared, hand-fed gharial were unable to catch live prey. In some areas such as the Satkoshia Gorge Wildlife Sanctuary only two out of 700 released animals remain (a mortality rate of 99.7%). In Katerniaghat Wildlife Sanctuary four nests were recorded in 1977, but the release of 909 gharial (including 112 in 2006) in the following years resulted in 20 nests in 2006. This implies a mere 2.5% of thirty years of reintroduction efforts. In the Chambal, despite receiving the lion’s share of funds and captive-reared gharials, there were only 68 nests recorded in 2006, up from 12 in 1978. Again this represents only 2% of the reintroduction efforts. While conservation studies worldwide have demonstrated that habitat protection is all that is needed for a species to recover, reintroduction is a radical intervention generally reserved for a stage of no return.

For the past decades, surveys revealed annually increasing numbers of gharial and this fact was used to claim that conservation efforts had been a great success. But the point is, gharial numbers were being artificially boosted by reintroductions every year. So the moment the head-starting program came to a standstill, the numbers of wild gharial plummeted. If success is measured by the ability of a population to self-sustain, the question that needs to be asked is - did gharial reintroductions ever achieve conservation success? While some conservationists argue that extinction had been averted by such sustained releases, it is also possible that the modicum of protection given to the habitats was the cause of the increase in nest numbers. The important thing to realize is that the reintroduction of gharial did not lead to the re-colonization of habitats such as Ken and Satkoshia where no nesting has been recorded in decades. The four existing breeding populations – Chambal, Katerniaghat, Son and Rapti-Narayani (Nepal) – already had reproducing females when these efforts began.

The head-starting program has never complied with any of the norms laid down by the 1998 IUCN Guidelines for Reintroductions. Given that the threats to gharial have never been addressed, nor existing conflicts mitigated, it makes little sense to keep dumping thousands of hapless young gharial (most to face certain death) into the rivers. Even captive reared adults were reintroduced with little or no effort spent on maximizing their chances of surviving in a landscape to which they were ill adjusted. Despite the enormity of past failure, reintroductions have not stopped nor critically evaluated. On the contrary, the pressure to allow such arbitrary releases is high even today, because of captive breeding successes, resultant overcrowding in zoos and rearing centers, and the “feel-good” factor. So why don’t the managers stop the captive breeding? For fear of reduced budgetary allocations in the subsequent years and indeed, more gharial are slated for release in the coming winter months.

Head of the table
The gharial requires deep, free-flowing rivers unfettered by dams and barrages. Fish, the prey of gharial (otters, river dolphins and several species of water birds), need clean and clear water to breed. Gharial must have undisturbed sand banks to bask and nest. We are also talking here about an intact, protected river habitat, on which our own survival hinges. Ecologically, the passing of the gharial signifies a collapsed ecosystem – polluted waters, drastic drop in water levels, erosion and siltation – all conditions that make any life in the rivers untenable. People need to see the gharial for the critical environmental services it offers – it eats the predatory catfish thereby boosting the productivity of fish yields, and it cleans up the injured, sick and unfit fish from the genetic pool; it plays the same role of top predator of the rivers that the tiger plays in the forest. The wise ancients recognized the critical role played by the gharial and made it the steed of none less than Ma Ganga herself, making it the cultural and ecological icon of the most sacred river in the world.

New Directions in Gharial Conservation
The gharial and its fellow river fauna really need the support of policy makers who should re-evaluate the proposal to interlink our rivers (thereby dooming them). The past mistakes have demonstrated the need to redress conservation priorities more broadly if the gharial and other riverine species are to survive. India is the only long-term hope for the gharial in the world.

The Madras Crocodile Bank based Gharial Multi-Task Force (GMTF) has set a science-based agenda that will identify threats to the species, survey historic habitats, such as the Brahmaputra, which are currently devoid of any gharial population, study the ecological role of the gharial, while also working with social scientists to understand the alternate livelihood needs of the people in the hope that they will once again accept the gharial as the icon of their river. The GMTF hopes to re-orient the gharial conservation strategy using science while accepting that wildlife management is really no more than people management in this situation – if all the human generated pressures are minimized, the species will automatically respond. It is only in extreme cases where a habitat exists but the species has been extirpated that intrusive animal management such as reintroduction is needed.

River Watch, a partnership between GMTF and the Worldwide Fund for Nature-India, is still in its formative stage and realizes that if our rivers are to survive, an integrated conservation plan is needed. It will focus on habitat protection while bringing together conservationists working for all river fauna, including the highly endangered Ganges river dolphin, smooth coated otters, mahseer and several species of endangered freshwater turtles, under one umbrella. River Watch, based in the WWF-India office in Delhi, intends to prioritize river conservation by drafting Management Plans for the various Protected Areas along river systems, developing and strengthening the policy and legislation for Integrated River Basin Management and lobbying for their implementation. While it will coordinate between departments such as Irrigation, Fisheries and Forest, River Watch will also network with our neighbouring countries such as Pakistan, Bangladesh, Nepal, Bhutan and Myanmar. It will campaign against over-harvesting of fish and water as well as any construction on rivers that works to the detriment of its habitat and fauna. It hopes to formulate guidelines for river ecotourism as well as promote use of safe fishing gear and teaching fishermen how to deal with accidentally captured gharial and dolphins. River Watch will collaborate with national and international partners in conservation, research and education to achieve its goals.

Gharial: the icon of civilization
It is not mere coincidence that all the great civilizations of the world rose on the banks of rivers. Rivers are still the lifeline of our existence, for example, the Indus and Ganges river basins support more than 10% (600 million people) of the world’s population. By working to conserve such animals as the gharial and river dolphins, we are in reality only preserving our very own life support system. While the pressures on rivers increase day by day, we are guardedly optimistic that people are already seeing reason and are finally ready to save the gharial and the rivers that are its home.
