I wish you all a happy and prosperous New Year – 2013. The year 2012 is of great importance both for India and the West Bengal Biodiversity Board (WBBB). Being a mega-biodiverse country, India’s response to lead global meet - the Eleventh Conference of Parties(CoP-11) to the Convention on Biological Diversity from 8-19 October, 2012 in Hyderabad, during the United Nations Decade on Biodiversity (UNDB, 2011-2020), has been well recognized. The members of WBBB, practitioners in conservation and develop-ment, are happy and inspired after their active participation in this important event.

A Ministerial dialogue on ‘Biodiversity and Livelihoods’ was the prime topic of discussion in this Conference. Approximately 6000 delegates representing 193 countries participated in the meeting. The conference adopted 33 decisions on the issues relating to the status of the Nagoya Protocol on Access to Genetic Resources and Benefit Sharing (ABS); implementation of the Strategic Plan 2011- 2020 and the Strategy for Resource Mobilization to achieve the Aichi biodiversity targets. The delegates also addressed many other issues like financial mechanism; cooperation; marine and coastal biodiversity; biodiversity and climate change; biodiversity and de-velopment; and several ecosystem-related and other issues. The Board is also making sincere efforts in implementation of many of the issues discussed in CoP-XI, particularly of the Nagoya Protocol on ABS. The Board is one of the five States in India where the studies on ABS with financial assistance from UNEP-GEF Fund has been initiated.

It is well recognized that the knowledge of biodiversity and aware-ness about its importance is still insufficient. The Board is paying special attention in evolving new methods of imparting knowledge of biodiversity to the people and has decided to start training course to develop village level para-taxonomists.

The present issue contains two articles - related to livelihood devel-opment through sustainable utilization of bioresources and aware-ness generation on the national aquatic animal – the Gangetic Dol-phin. I sincerely thank Prof. Joydeep Mukherjee, Jadavpur Univer-sity and Dr. Sangeeta Mitra, WWF-India for their cooperation in enriching the issue with their articles. I am happy that this newslet-ter has come out in time for which I express thanks and best wishes to all my colleagues specially Dr. Anirban Roy and Mrs. Tuli Ban-dopadhyay in the Board.

Microbes of the Sundarbans: a new opportunity for biotechnoogy?

Joydeep Mukherjee M. Tech. (Biotechnology) Ph.D. (Engg.) School of Environmental Studies

Jadavpur University

A population of approximately 3.2 million inhabits the Indian Sundarbans. People are poor and they subsist on single crop agriculture, fishing, honey and wood collection from the forests. In the absence of any alternate employment, they depend on traditional skills to earn their livelihood and depend largely on forest resources like firewood, timber wood, honey, beeswax, Golpata and tend to resort to illegal practices like poaching and felling. They collect tiger shrimp seeds in large numbers thereby causing damage to juvenile fish stock and mangroves. Agriculture is highly unbalanced, mostly monoculture and the daily income of the local people involved in agriculture are as low as Rs.5 to Rs.12 per day [1]. Of major economic, environmental and social importance, industrial biotechnology involves the utilization of microorganisms in the production of a wide range of products, including pharmaceuticals, enzymes, foods, beverages, chemical feed stocks and fuels. The worldwide sale of medical and pharmaceutical drugs of micro-bial origin now exceeds US$ 13 billion annually. The global market for industrial enzymes is forecast to reach US$ 3.74 billion by the year 2015 [2]. Is this huge business potential of industrial biotechnology of relevance to the local people of the Sundrabans? In India, public as well as private research funding is now being di-rected to utilize microbial resources for business in biotechnology. A national level project sponsored by the Council of Scientific and Industrial Research (CSIR), Government of India, on the exploration and exploitation of the microbial wealth of India involves eleven research institutes. In a first-of-its-kind partnership, the Rs. 3000-crore pharma company, Nicholas Piramal has signed an agreement with the Department of Biotechnol-ogy (DBT), Government of India to jointly screen for functional biomolecules from microbes. The project cost is about Rs. 25 crores, of which Rs 17.98 crores will be contributed by DBT and Rs. 6.88 crores by Nicholas Piramal. Although the diversity of flora and fauna of the Sundarbans is well-recognized, it is surprising to know that the microbial biodiversity of the world’s largest tidal mangrove forest and the industrial biotechnological po-tential of this immense biological resource are unheard of. On the premise that poorly researched habitats can offer better prospects for discovering new natural products, microbes from such habitats are currently being the focus of great international scientific interest. One such scantily explored habitat is the estuarine mangroves which form the margins of the terrestrial and marine ecosystems and are known to be highly pro-ductive and diverse ecosystems. It is believed that this ecosystem has the potential to become a new resource for bio- and chemodiversity, given salinity to be the prime determinant of bacterial diversity. Recent research efforts at Kolkata based institutions show that microbes of the Sundarbans can be harnessed for commercial utilization. Joint research programmes by Jadavpur University, Indian Institute of Chemical Biology and Peer-less Hospital have led to the discovery of a new bacterium, Streptomyces sundarbansensis, the first validly de-scribed marine bacterium from India as well as novel enzymes and antimicrobials of commercial importance from the microbial diversity of the Sundarbans [3-11]. Researchers from the University of Calcutta have re-ceived funding of Rs. 5.6 crore from the World Bank to catalog the unknown microbial diversity of the Sundarbans. The Department of Biotechnology, Government of India is submitting a proposal of Rs. 25 crores to the Planning Commission to search for novel microbes producing new pharmaceuticals along the entire Indian coast including the Sundarbans. A report on the status of biotechnology industry in India published in ‘Biospectrum.’ on 18th October, 2006 highlighted the potential of obtaining commercially valuable biochemi-cal and genetic resources in the Sundarbans [12].

The Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from-their Utilization to the Convention on Biological Diversity is an international agreement which aims at sharing the benefits arising from the utilization of genetic resources in a fair and equitable way, including by appro-priate access to genetic resources and by appropriate transfer of relevant technologies, taking into account all rights over those resources and to technologies, and by appropriate funding, thereby contributing to the con-servation of biological diversity and the sustainable use of its components. It was adopted by the Conference of the Parties to the Convention on Biological Diversity at its tenth meeting on 29th October 2010 in Nagoya, Japan [13]. In India, as well as in the world, a well-known astoundingly successful example of access to genetic resources and benefit sharing is the Kani-TBGRI (Tropical Botanic Garden and Research Institute, Trivan-drum) model in Kerala. In 1987, a team of scientists from the TBGRI undertook an ethno-botanical study in the Western Ghats of Kerala. During this expedition, the scientists observed that the accompanying Kani tri-balmen frequently ate some fruits of a plant that kept them energetic during the long periods of walking through the forests. Although the Kani men were initially reluctant to reveal the secret, they did so once con-vinced by the scientists that their traditional knowledge would not be misused and that, they would conduct scientific investigations on the plant. If any commercial drugs/products could be eventually developed, the profits would be shared with the tribals. The Kani tribe then disclosed the ‘magical’ plant, which was later identified as Trichophus zeylanicus. Pharmacological investigations of the fruit confirmed its anti-fatigue prop-erties. Detailed chemical and pharmacological investigations showed that the leaves contained various glycol-ipids and some other nonsteroidal compounds possessing anti-stress and anti-hepatoxic properties. The sci-entists developed a polyherbal formulation that was named ‘Jeevni’. After satisfactory clinical evaluation this herbal drug was released for commercial production. The manufacturing license of ‘Jeevni’ was transferred to the Aryavaidya Pharmacy Coimbatore Ltd. for a licence fee of Rs. 10 lakhs for a period of seven years. Keeping the promise made to the tribals, TBGRI in consultation with the community worked out an arrangement for benefit sharing. According to this agreement, the TBGRI has consented to share 50% of the license fee and royalty with the tribal community [14]. Can this spectacular partnership model be exemplified with the mi-crobes of the Sundarbans? After a recent field survey conducted by the Institute of Forest Productivity, Ranchi, the scientists reported that 17 species of the medicinal plants and trees are being felled in the Sundarbans [15]. While conservation of vegetation and natural regeneration of the plants should be undertaken, the exploitation of the untapped mi-crobial resources should also be immediately initiated. The study of microbial diversity is important to ad-vance biotechnology. New technologies, particularly in habitat sampling and characterization, nucleic acid analysis, computer science, analytical chemistry, molecular biology and biochemical engineering place the realm of microbial diversity on the cutting edge of science. Governmental policies and private entrepreneur-ship should promote serious microbial bioprospecting efforts in the Sundarbans in accordance with the tenets of the CBD, ensuring fair and equitable sharing of profits with the local people. The microbial resources are renewable; therefore there would be no requirement of expensive aquacultural equipment or agricultural cul-tivation in the ecologically sensitive area. Industrial production with modern process-controlled reactors would allow intensive production in factories far way from the Sundarbans. This would, in turn, promote in-dustrial development and provide employment opportunities. Finally, commercial successes would bring huge revenues that can be distributed among the local people of the Sundarbans, thus relieving them of the current ecosystem-damaging livelihoods like fishing and agriculture.

Ganges River Dolphin in India Dr. Sangeeta Mitra, WWF-India, Kolkata

Platanista gangetica gangetica at the mouth of River Distribution map of Dolphins in West Bengal Rupnarayan Common Name : Susuk; Ganges river dolphin Scientific name : Platanista gangetica gangetica (Roxburgh, 1801) Geographical range : Ganga, Brahmaputra, Meghna, Koshi River systems of India, Bangladesh and Nepal respectively. Status: The total population is estimated to be around 1700 individuals in its entire distribution range within Indian Terri-tory. This species has been included in Schedule I of the Indian Wildlife (Protection) Act 1972, in Appendix I of the Convention on International Trade in Endangered Species (CITES), in Appendix II of the Convention on Migratory Species (CMS) and categorized as Endangered in 1996 on the International Union for the Conservation of Nature's (IUCN) Red List. The first efforts in the 20th century to document the status and threats faced by the Ganges River dolphin were made under the Ganga Action Plans (GAP) I (1985) and II(1991) through research and conservation projects. Habitat : It prefers to stay in deep water in and around the confluence of two or more rivers. Morphology: Greyish brown or slaty coloured, smooth and hairless skin in adults. Calves are chocolate or dark brown at birth. Females are larger than males. Length : 2.7m or 9 ft ( in female), 2.12m or 7ft ( in male) Body weight : Around 150kg (average) Food & Feeding : Ganges River dolphins feed on several species of fishes, invertebrates and possibly turtles and birds. Life cycle & Reproduction: Females give birth to only one calf every 2/3 years after a gestation period of 9-11 months. Average life span is 25-28 years. Though the breeding season of the Gangetic dolphin extends from January to June, newly born calves can be seen even in other months. While mating usually takes place between March and June, it has been observed even in July.

Significance: The Ganges dolphin is an indicator species for the river ecosystem and is at the apex of the food chain. It is an en-demic and rare aquatic mammal found only in the Indian subcontinent and is part of our natural aquatic heritage. The species has been declared the ‘National Aquatic Animal’ by the Government of India(2010) . Speciality: Dolphins cannot see but emit an ultrasonic sound, that hits an object or any prey inside water. This is called echo-location. Threats: India lost 65% of its river dolphins in the last 25 years because of drying up rivers, low flow, pollution, over fishing, developmental activities and water structures, entanglement in fishing nets or injury by river traffic and hunting of dolphins for oil and other body parts.
