N; Singh. G; Singh. C.K. & Alkesh. S (2007). Biological Diversity:The Very Stuff of Life. Punjab Biodiversity Board, Punjab State Council for Science & Technology, Chandigarh and UNESCO, New Delhi © PBB, PSCST & UNESCO, 2007 Foreword T he variety of life on earth is recognized as an essential part of our planet’s life support system. However, the over-exploitation of nature through human pressure is causing the rapid and irreversible loss of our biological diversity. Global changes, particularly climate change, have a further negative impact. The threat to biodiversity is closely linked to issues of sustainable and equitable development, including poverty alleviation. The task of development is to provide all people with opportunities for a better quality of life through access to resources. However, there are real concerns about whether development will cause serious environmental damage that can itself adversely affect quality of life; or whether environmental and natural resource constraints will limit development. Since the early 1970s, UNESCO has recognized the role of humans in the ecosystem and has manifested its concern through the Man and Biosphere (MAB) programme. It recognizes that peace, development and environmental protection are inter-dependent and indivisible, and that these issues are best handled with the participation of all concerned. UNESCO works to provide sound, reliable and timely information to people and governments to ensure comprehensive environmental management, prevent over-exploitation of natural resources and promote environmentally sound development. This publication is part of the UNESCO initiative on “Minimizing Biodiversity Loss through Research and Capacity-Building for Ecosystem Management”, which is being implemented through the Punjab State Council for Science and Technology (PSCST). This initiative involves capacity building of local stakeholders and communities dependent on biological resources for their livelihoods in the biodiversity-rich areas (Shivaliks and Ramsar Sites) of the State of Punjab in northern India. This publication also forms part of an educational kit developed jointly by UNESCO and PSCST to present biodiversity issues to local populations, make them more aware of the value of their natural biological resources and motivate them to take positive action to conserve them. The livelihood needs of traditional societies living close to nature and natural resources are a key element of sustainable development. I hope this publication will therefore be of interest to conservation managers, researchers, governmental and non-governmental organizations, students and teachers, and to all those committed to the management of biodiversity for sustainable development. Minja Yang Director, UNESCO New Delhi Office H uman society is today faced with an ecological crisis of its own making. The planet is faced with an accelerated rate of extinction of floral & fauna species, climate change, natural disasters like droughts, storms and floods due to uncontrolled ecological destruction caused by perilous and unregulated urbanization and industrialization and increased consumption of resources by the increasing population and market driven societies. The consequences of this would not only alter our lives in the immediate future but that of our future generations, if appropriate actions are not initiated immediately. Closer home in India shrinking cover of natural forests, rapidly falling groundwater levels, variations in rain fall pattern, rising temperatures, receding glaciers, desertification, rapid loss of biodiversity and falling agricultural productivity indicate the deteriorating health of our ecosystems. Central to this malaise are two basic misconceptions - the belief that man can dominate over nature, and that only economic growth can offer a better future. We need to keep in mind that human society is a subset of the environment and its well being depends upon the well being of our biosphere. Nature cannot be relegated to be as just a raw material on a free good and the ecological complexities needs to be respected and understood and economies need to be built on existing ecological, social and cultural realities. This book is a part of a kit developed under a UNESCO sponsored project to build capacities of local populations to promote environmental sustainability through biodiversity conservation. It is designed to provide some basic information on biodiversity to facilitate a dialogue amongst diverse groups within local communities and build their capacity to understand local biodiversity issues and take informed decisions for promoting sustainable utilization of their biological resources. The kit, including this book, is targeted to a broad range of stakeholders, representatives of villages, panchayats, social society organizations, government functionaries, youth, teachers and students so that a better stewardship emerges within local communities and they are motivated to take positive action for conservation, protection and sustainable utilization of their resources and associated traditional knowledge. It is hoped that armed with some basic information, communities would be in a better position to ensure equitable sharing of benefits arising out of these resources and knowledge.

This web is intricately linked and consist of millions of species inhabiting land, fresh water and oceans. Together, they constitute our biological diversity - including every living thing on the earth, from the minutest microbes to the tallest trees, the genes they contain and the ecosystem of which they are a part. The term ’Biodiversity’ was coined by E.O. Wilson in the late 1980s, who referred it to as ‘the very stuff of life’. Ecologists define it as the totality of genes, species and ecosystems in a region. For Geneticists, biodiversity also includes genome dynamics that occurs at the DNA level and leads to evolution. Biological diversity is generally described in terms of three hierarchical levels: genes, species and ecosystems. Genetic Diversity Genetic Diversity includes the diversity of the basic units of hereditary information (genes) within a species, which are passed down the generations. It is this type of diversity which results in several varieties, breeds or land races; e.g. more than 40000 varieties of rice or about twenty breeds of cattle are known to have occurred in India, each adapted to its own unique environment. Some variations are easy to see, for example, size or colour; some, such as taste or flavour, can be perceived by other senses; and some are invisible, such as susceptibility to disease. Biological Diversity Maintaining genetic diversity within a group of plants or animals is extremely important because it allows populations to adapt when changes occur in their environment. If populations become too small, genetic diversity is lost. Populations that have little genetic diversity are often more vulnerable to outbreaks of disease or pest infestations. Species Diversity The variety and abundance of different types of organisms which inhabit an area, each distinct from another and reproducing within its own group, constitutes species diversity. It includes all organisms from amoebas to elephants, or the giant Sequoias, that currently exist or have ever existed on our planet. So far, approximately 1.4 million living species have been identified. These include about: 10,000 species of viruses and bacteria 120,000 species of non flowering plants 270,000 species of flowering plants 1,200,000 species of invertebrates 46,000 species of vertebrates (including about 5000 species of mammals, 9,000 species of birds, 10,500 species of reptiles and amphibians, 19,000 species of fish) Biological Diversity Certain species called ‘keystone species’, play a critical role in an ecosystem as they affect abundance & health of many other species e.g. Corals in tropical coastal waters. Some species called ‘Endemic species’, are found exclusively in a particular area, indicating the existence of a unique habitats in a limited geographical area e.g. the Great One Horned Rhinoceros is found only in India, Bhutan & Nepal. If these habitats are damaged it almost certainly means that the endemic species will die. However, some species, such as grass and sparrows, occur commonly around the world. Species diversity is most commonly used for describing the biodiversity of countries. Based on this a few countries have been identified as “mega diversity” countries. These are: Australia, Brazil, China, Colombia, Ecuador, India, Indonesia, Madagascar, Malaysia, Mexico, Peru and Zaire (McNeely et.al., 1990). Ecosystem Diversity An ecosystem is ‘a set of life forms (plants, animals and micro-organisms) interacting with one another and with the non-living elements (air, soil, water, minerals, etc.) of their environment’. Ecosystem diversity is therefore the diversity of habitats (i.e. the place or site where an organism or a population of organisms naturally occurs), which support different life forms. Ecosystem diversity refers not only to the variety of species within a particular ecosystem (the more the number of species within an ecosystem, more diverse that ecosystem is considered to be) but also to the variety of ecosystems found within a biogeographical area or a political boundary. Major ecosystems in the world include: Natural Terrestrial Forests Grasslands Tundra Deserts Manmade Crop fields Gardens Aquatic Marine Oceans Estuaries Coastal areas Freshwater Rivers Springs Ponds, lakes & wetlands Bogs Biological Diversity When we think about biodiversity, we generally take into account only wild plants and animals. But a vast diversity exists amongst domesticated plants and animals also. This is due to: adaptation of crops & domesticated animals to different climatic and geographical conditions e.g. a variety of rice grown in the hills could develop characteristics to withstand cooler temperatures than a variety grown on hot and humid coastal areas or a breed of cow or goat found in the Himalayas would be different than the breed which can withstand the hot conditions of Rajasthan. manipulation by humans to produce new varieties of crops and breeds of domesticated animals for better productivity, taste, resistance of diseases, ability to withstand floods & droughts, etc. Further, we also need to take into account micro-organisms. A teaspoonful of soil could contain billions of these microbes, including bacteria, viruses, fungi, protozoons, etc. which play an important role in the biogeochemical cycles. Biodiversity also includes the vast array of human beliefs, knowledge, traditions, customs, and languages that create the framework for society. This constitutes cultural diversity. For example, religious beliefs can affect a community’s diet and the crops they choose to grow (and how they grow them) or the animals they tend to rear, traditional knowledge can determine how certain plants and animals or their parts are used for health care, while social status within a group can affect a culture’s land-management practices. Biological Diversity The value of Biodiversity All organisms have value, whether we can see their direct benefits or not; for example, we do not like many insects in our homes or gardens but they are vital as they pollinate flowers, recycle garbage and are food for many birds, reptiles and mammals. Hence, Biodiversity forms the very foundation of human existence. For most developing countries, perhaps the most important value of biodiversity is that it meets basic survival needs of millions of people. Several traditional societies depend wholly or partially on their surrounding natural resources to meet their daily needs of food, shelter, clothing, medicines, etc. Besides these, biodiversity also provides livelihood opportunities and satisfies spiritual and recreational needs of people. At the ecosystem level it renders important services like, air & water purification, climate control, prevention of floods & droughts, seed dispersal, pollination, etc. Besides, it also provides the conditions that drive the processes which sustain global economies and are essential for the very survival of species. The benefits and services provided by biodiversity include: Food Security Biodiversity provides the vast majority of our food stuffs. More than ninety per cent of the calories consumed worldwide come from about 80 plant species, out of which about sixty per cent are provided by four major species i.e. wheat, corn, rice & Biological Diversity potatoes. There are however, a host of plant & animal products which contribute towards meeting nutritional requirements of people. Many of these foods are especially important when agricultural supplies fall. Further, wild biodiversity provides the genes required to modify crops which help maintain crop productivity by offering resistance to pests & diseases. Higher diversity in agricultural fields also acts as a Food Security System. Health Care The World Health Organization estimates that eighty per cent of people in the developing world rely on traditional medicines derived mainly from plants. In Southeast Asia, for example, traditional healers use about 6,500 different plant species to treat various types of diseases of humans and cattle. Biodiversity is also important for the ‘formal’ health Traditional medicine in India depends upon its sector. Approximately 110 out of 150 rich biological resources. The three traditional drugs used in India are based on natural systems of medicine include – Ayurveda, Sidha sources. Of these, 74 per cent are & Unani. derived from plants. Microbes and animal As per the Ayurvedic system, all plants on the species have also contributed a range of earth have medicinal properties. A mythological medicines, including Penicillin (derived story says that once Brahma, the creator, ordered from the fungus Pencillium notatum) and sage Jivaka to find a tree or a herb which had no several drugs – including anesthetics– medicinal value. Jivaka wandered over the earth derived from the skin secretions of treefor eleven years but returned empty handed; frog species. The medicinal importance but much to his surprise, Bhahma recognized him as a great physician. The study of Ayurveda of biodiversity is particularly impressive followed. considering that only a tiny fraction of earth’s species have been thoroughly Adapted from: Jain, 1995 as cited in Bhatt, 1996 investigated for medicinal properties. The investigative process is continually turning up new pharmaceuticals of great promise. A recent study of cone snails, for example, has identified a painkiller that is up to a thousand times more effective than morphine, but without morphine’s addictive properties. Biological Diversity Fuel, Timber, Fibre and other resources Most of our clothes, houses and furniture are made from natural products. Further, many non timber products like oils, resins, waxes, gums, etc. are obtained from natural resources. The wool from sheep and cocoons of silk worms form the basis of the valuable art of knitting and silk making industry. The extraction of rubber, resins, catechu, toddy, etc. contributes to local economies. Ecosystem Services Biodiversity provides us with many life sustaining services which have a much higher value than we generally realize, like: Purification of air and water by recycling oxygen and carbon dioxide and filtering harmful air pollutants or absorbing water pollutants. Also preventing eutrofication of water bodies. Carbon sequestering, helping to reduce global warming. Recycling nutrients in the soil by breaking down organic matter especially due to the activity of microbial species, thus maintaining soil quality. Biological Diversity Protecting landscapes against erosion & landslides through the binding action of roots, thus preventing natural disasters. Also protecting lands from droughts and floods. Climate stabilization by giving off moisture (during transpiration), providing shade and acting as wind breaks. Pollination and seed dispersal Controlling pests – most potential crop pests are controlled by a variety of other organisms including birds, reptiles, insects & fungi. Decomposition of wastes, especially from industries and their detoxification through the action of micro organisms. Biological Diversity Livelihoods Biodiversity has great importance as a direct source of income and economic development especially in traditional communities where several plants & animal products are derived from the natural ecosystem and processed to form products of economic value. It also serves as an income generating activity through nature tourism. Worldwide ecotourism contributes to more than $500 billion every year. 10 Biological Diversity Inspirational & cultural value The religious and ethical beliefs of cultures around the world include respect for and protection of nature. Some common examples in India where plants and animals are revered include the ficus tree, the basil plant or the holy cow. Biodiversity has, over the ages, inspired songs, stories, dances, poetry, crafts, myths, cuisines, rituals and festivals. Further, nature is an unsurpassed source of relaxation, beauty, rejuvenation and peace. Biological Diversity 11 Distribution of biodiversity It is important to realize that biodiversity is not evenly distributed on the earth. Its distribution depends on climate, soils and the presence of other species. Some areas, like the tropics are biologically very rich areas whereas others like deserts or snow covered areas, harbour lesser number of plants and animals. Nevertheless species found in such ecosystems are equally important as they are adapted to specific conditions. A major regional community with its own type of climate, vegetation and animal life, is called a ‘biome’. Biomes are not sharply separated, but merge gradually into one another. This overlap area is called an ‘ecotone’. India contains a great wealth of biological diversity due to the wide variety of climatic and geographical conditions and is one of the centres of mega diversity on the earth. Most biologically rich areas in the world are known to lie around the equator. Areas with very high biodiversity are known as ‘hotspots’. These hopspots were first identified by Norman Myers, a British Environmental scientist. Out of 34 hotspots in the world, two hotspots are in India - the Eastern Himalayas and the Western Ghats. Source : Conservation International, 2005 12 Biological Diversity Himalaya – The Himalaya Hotspot is home to the world’s highest mountains, including Mt. Everest. The mountains rise abruptly, resulting in a diversity of ecosystems that range from alluvial grasslands and subtropical broadleaf forests to alpine meadows above the tree line. Vascular plants have even been recorded at more than 6,000 meters. The hotspot is home to important populations of numerous large birds and mammals, including vultures, tigers, elephants, rhinos, and wild water buffalo. Western Ghats – Faced with tremendous population pressure, the forests of the Western Ghats and Sri Lanka have been dramatically impacted by the demands for timber and agricultural land. Remaining forests of the Western Ghats are heavily fragmented. The region is home to a rich endemic assemblage of plants, reptiles, and amphibians, as well as important population of Asian elephants, Indian tigers, and the Endangered lion-tailed macaque. Biological Diversity 13 Status of Biodiversity in India India supports about five per cent of the world’s biodiversity on two per cent of the earth’s surface. About 45,000 species of wild plants representing approximately seven per cent of the world’s flora and approximately 80,000 species of wild animals representing about 6.4 per cent of the world’s fauna is found in India. It is estimated that out of 15,000 flowering plants found in the country, about 4,900 species are endemic (Ministry of Environment & Forests, Govt. of India, 1994). In contrast, Brazil, the richest nation w.r.t. biodiversity, has 55,000 species of flowering plants. Amongst Asia, China is the richest with 30,000 flowering plants. Animal diversity in India includes more than 370 mammals, 1200 birds, 425 reptiles, 200 amphibians, 2500 fish and more than 20,000 species of invertebrates. Out of these 38 mammals, 69 birds, 156 reptiles and 110 amphibians are endemic. However, Indonesia is the world leader with respect to mammal population as it harbours 515 species out of which 165 are endemic. China and Brazil have 394 mammal species. Bird species are highest in Colombia (1721 species), reptiles are Mediterranean 5 Iraq 4 7 Meso America Turkey 3 2 India 8 Andes 8b 8a Vavilov’s Eight Centers of Crop Origin Source : www.hort.purdue.edu 14 Biological Diversity 1 China 2a SE Asia Centres of Plant Biodiversity In 1951 Russian Scientist N.Y. Vavilov, on the basis of worldwide field surveys by his team, classified the world’s crop producing regions into eight centres of plant origin. Of these areas of crop genetic diversity, India was central to what he called the “Hindustan Centre of Origin”. Vavilov’s terminology was well justified because the Indian region is known to be endemic for a considerable number of major crops. At least 166 species of crops (6.7 per cent of total crop species in the world) and 320 species of their wild relatives are believed to have originated here. The Green Revolution in the late 1960s and the 1970s enabled India to increase agricultural productivity dramatically and made it selfsufficient in food. This was possible through the use of high yielding varieties (HYVs) of crops. But areas where HYVs were favoured have lost many traditional low input demanding varieties leading to loss of rich diversity. Punjab is one such area. HYVs favour genetic uniformity which makes the crop vulnerable to pests and diseases. Indigenous varieties have been noted to have a greater ability to withstand adverse conditions like drought, floods, soil imbalances and diseases. Adapted from: Bhatt, 1996 highest in Mexico (717 species) closely followed by Australia (700 species) and maximum amphibian species are recorded in Brazil (502 species) (NCSTC – Network, 2007). Within the country, Punjab fares well with respect to birds as more than 400 species have been recorded from the Shivalik foothills and the state’s wetlands. Domesticated biodiversity is also high in India. With 51 species of cereals and millets, 104 species of fruits, 27 species of spices and condiments, 55 species of vegetables and pulses, 24 species of fibre crops, 12 species of oil seeds, the country is considered to be one of the world’s eight centres of origin of cultivated plants (Box). Several hundred species of wild crop relatives are also distributed all over the country, especially in the Eastern or Western Himalayas, Western Ghats, Deccan Plateau and the Gangetic plains. Citrus indica the most primitive species of citrus plants, is found in Tura hills of Meghalaya, where as the Deccan Plateau is home to wild rice. Amongst domesticated animals, the country harbours 26 breeds of cattle (including all the 8 breeds of buffaloes), 40 breeds of sheep, 20 breeds of goat, 8 breeds of camels, 6 breeds of horses, 2 breeds of donkeys and 18 breeds of poultry. However, many of these are now under threat. Threats to Biodiversity Extinction of some species and evolution of new ones is a natural process. In nature these processes occur at a roughly equal rate. However, off-late, the rate of extinction has outstripped the rate of evolution of new species. This indeed is a cause of concern. In India alone, 247 species of plants and 313 species of wild animals have been identified under various threat categories by IUCN (Box). One mammal (Cheetah) and one bird species (Pink headed duck) and at least twenty species of higher plants are also reported to be extinct from India (Bhat & Deshbandhu, 1994). Threatened Species in India Group Number of species Animals 313 (CR:44, EN:88, VU:181) Mammals 89 Birds 75 Reptiles 25 Amphibians 63 Fishes 39 Molluscs 2 Other Invertebrates 20 Plants 247 (CR:45, EN:113, VU:89) Total 560 Source: 2007 IUCN Red List, www.iucnredlist.org CR: Critical (species facing extremely high risk of extinction) EN: Endangered (species considered to be facing very high risk of extinction) Vu: Vulnerable (species considered to be facing high risk of extinction) Biological Diversity 15 Further, genetic diversity within species is also being eroded. This trend is especially alarming from an agricultural perspective. Since 1900, about three-quarters of the genetic diversity of cultivated crops have disappeared, together with nearly half of the gene pool of wild relatives of domestic animals. Factors leading to Biodiversity Loss The major causes of biodiversity loss include loss of natural habitats, over use of natural resources, pollution, changing climate and invasive species. Lost & Found The Double banded Courser (Cursorius bitorquatus) was sighted by T.C. Jerdon in c.1848 in the Eastern Ghats of India. There is also a record of the bird’s sighting in 1871 in the Godavri River valley in Northern Andhra Pradesh. The last authentic sighting was in 1900 in Pennar river valley. Subsequent bird surveys conducted from 1929 to 1931 and during 1933-34 covering the range of habitat of the bird failed to spot it. Subsequently, special explorations were organized by Bombay Natural History Society in 1975 & 1976 in collaboration with Smithsonian Institution, USA and Worldwide Fund – India in the area but the bird remained elusive. This led several ornithologists to believe that the bird had become extinct. However, in January, 1976 the bird was re-sighted in Lanka Malia Hills in Pennar river valley in Southern Andhra Pradesh by a team of BNHS and US Fish & Wildlife Service Scientists. Habitats all over the world are changing because of disturbances created by humans like, cutting of forests, intensive industrialization, filling of wetlands, building new settlements, mining, etc. These actions change landscapes, Adapted from : Bharat Bhushan, 1986 alter natural flow of water and affect species composition. Many landscapes get eroded. Others get fragmented into smaller patches, isolating many species resulting in their inbreeding, loss of genetic diversity and local extinction. In India, fragmentation of forests has led to decline in elephant population. Further, some plants and species are used at a greater rate than at which they can replace themselves. This can lead to depletion of such species. Examples include over-exploitation of Rauvolfia serpentina and Diosoria deltoidea (yam) for extraction of reserpine and diosgenin drugs used as tranquilizers and for manufacture of contraceptive pills, respectively. Scientific studies also indicate that the global climate is changing with increase in industrialization and burning of fossil fuel. This results in an increase in carbon dioxide and other gases in the atmosphere leading to rise in global temperatures and change in natural climate, causing floods in certain areas and droughts in others. Effluents from industries and municipalities and 16 Biological Diversity run off seeping into rivers, lakes & coastal environments negatively affect the aquatic ecosystems. Chemical pesticides in the fields harm non-target wild insect pollinators. The pollution in the environment can also kill organisms or interfere with their vital life processes like, reproduction, thus affecting their future population. Studies conducted in the highly polluted Buddha Nallah in Punjab, a rivulet joining with river Satluj near the industrial city of Ludhiana, indicates loss of reproductive capacity in fishes occurring in about 40 km stretch of the rivulet. Further, people are also responsible for introducing exotic (non native) species in an area accidentally or purposefully. These species, generally, do not have their natural predators to keep populations in check. Hence, they affect the local species and invade large tracts of land and water. The weed Parthenium hysterophorus (Congress grass or gajarbootie) was introduced accidentally with wheat seeds imported from Mexico in the sixties. It is a highly invasive weed of Punjab affecting native flora & fauna. Similar is the case of weed Lantana camara which has invaded large forest tracts in the Shivaliks replacing local herb flora. Similarly, the weed Eichhornia crassipes (water hyacinth or pani di booti) was brought to India as an ornamental plant but has become a major aquatic weed invading and blocking water bodies. Further, economic systems and policies which fail to value the environment or address only short term developmental needs, breakdown of customary laws within communities, certain agricultural and forestry practices, unsustainable natural resource consumption, inequities in ownership, management & flow of benefits for use of biological resources and global trading systems which favour monocultures (especially of crops & fruits) also contribute towards biodiversity loss. The loss of biodiversity is affecting the natural ecosystems of the world and the valuable services provided by them. It is difficult to quantify these impacts but it is estimated that many varieties of food, medicines, timber, fuel and other resources will be lost for ever and many ecosystem services like, climate regulation, flood & drought control, nutrient recycling, clean air & water and pollination will be affected. This can have unforeseen affects on our resources and economy and can severely limit quality of life. Biological Diversity 17 Implications of Biodiversity Loss The continuous loss of biodiversity can greatly affect human society, as well as, ecosystems and their valuable services. It is, however, difficult to quantify these impacts. Biodiversity loss will not only limit our quality of life but would also undermine our potential to feed, clothe & shelter our future generations. It is not possible to accurately account for the cost of loosing yet undiscovered species which could be sources of new varieties of foods, medicines and other resources. Furthermore, the loss of ecosystem services such as pollination, clean air & water, climate regulation, drought and flood control and nutrient recycling will not only affect humans but have an adverse impact on all species of plants & animals. We also need to factor the cause of unknown ripple affect, which a change in one species or ecosystem, could have on other species and ecosystems on the planet. Loss of biodiversity can also have unforeseen affects on jobs and economy, e.g. loss of fish in aquatic ecosystems could affect fishing communities all over the world. Further, there is no way to estimate losses of emotional, psychological and spiritual well being which could result from degraded biologically rich areas. Slowing biodiversity losses If we wish to conserve our biological diversity and slow down its loss, we need to understand how nature works and our role in it. Studying biodiversity will help people understand the inter-linkages between biological resources and human well being and help them take best decisions regarding challenges associated with resource conservation and development. It is however, important to realize that conservation does not mean a moratorium to use; rather it promotes sustainable utilization. This is possible only if we are aware of our existing resources with respect to our requirements and aspirations and are willing to shun consumerism or forego certain short term economic interests for long term benefits. One way of slowing down biodiversity losses is to establish and protect specific areas with the goal of conserving both, species and natural ecosystems. There are 14 biosphere reserves, 94 National Parks, 502 sanctuaries, 2 Conservation Reserves under Protected 18 Biological Diversity Biodiversity Conservation – a traditional approach People in India, like people in other traditional societies throughout the world, have been conserving local biological resources since times immemorial. This is because our forefathers, who used local biodiversity and realized its importance in their lives, have ensured its survival by incorporating it in religion, rituals and customs. These traditions are responsible for the presence of thousands of peepal (Ficus religiosa) and banyan (Ficus benghalensis) trees all over the country and the persistence of monkeys (associated with the Hindu God, Hanuman) and peacocks (associated with Lord Krishna) in our villages & towns. The Bishnois are another important community with strong conservation tenets which practice a religion where conservation plays a key role. Two of the main tenets include ban on felling of any green tree and on the killing of any bird or animal. Today even after five centuries, the community follows these tenets and their villages stand out like oasis in the desert where even the shy wild black buck can be seen roaming freely. In Punjab, trees have been associated with Gurudwaras also. Researchers have documented 17 native tree species, associated with 48 sikh shrines. These trees were invariably the sites selected as halting places by the Sikh Gurus and their disciples for resting and preaching during their missionary tours. After their departure from the site, the trees were remembered for their association with the visit of the guru and later commemorated with construction of shrines. The most important of such sites is the ‘Dukh Bhanjani Beri’ at Baba Budha Ber Sahib (Zizyphus jujuba) at the Golden Temple at Amritsar. Other important Gurudwaras are Gurudwara Bohr Sahib (Ficus bengalensis) at Anandpur Sahib, Distt. Ropar; Gurudwara Imli Sahib (Tamarind) at Kiri Afgana, Chamkaur Sahib, Ropar; Gurudwara Kalp Vriksh (Mitragina parvifolia) at Village Attari, Ropar; Gurudwara Pipli Sahib (Ficus religiosa) at Amritsar; Gurudwara Jand Sahib (Prosopis spicigera) at Gumti Kalan, Bathinda; Gurudwara Phalahi Sahib (Acacia modesta) at Lakhisar, Bathinda; Gurudwara Garna Sahib (Capparis horrida) at Bodal, Dasuya, Hoshiarpur; Gurdwara Harian Velan Sahib at Bajraur, Hoshiarpur; Gurudwara Tahli Sahib (Shisham) at Munak Kalan, Nawanshahar; Gurudwara Nim Sahib (margossa) at Akar, Patiala; Gurudwara Reru Sahib (Mimasa leucophioea) at Rampur, Ludhiana; Gurudwara Karir Sahib (Capparis aphylla) at Littar, Ludhiana and Gurudwara Ber Sahib (Zizphu jujuba) at Sultanpur Lodhi, Kapurthala. Outside Punjab, Gurudwaras at Leh and Uttaranchal are also associated with Datun (Margossa) & Ritha (Sapindus mukorossi) trees, respectively. Adapted from: A Tryst with Trees by Jaspal, 2007 Biological Diversity 19 Area Network in the country besides additional 24 Bird protected areas (IISc, 2007). Efforts have also been made to protect certain key stone species through special projects like, Project Tiger, Project Elephant, etc. In the state of Punjab, though only 6.5% area is under forest cover, however, 11 areas have been identified under Protected Area Network. These include 7 wildlife sanctuaries, one conservation reserve, 3 birs (areas protected by erstwhile kings) and 4 rakhs (areas protected traditionally through community participation). Conservation efforts, however, must respect the rights of indigenous people who live close to such areas and often draw their sustenance from resources in such areas. Ecological restoration is another process of bringing the degraded ecosystems back to their original state. This involves recolonization of native plant and animal species and re-establishment of ecosystem processes. Several such efforts are being made throughout the country. Botanical Gardens and Zoos also play an important role in conserving endangered plant and animal species besides serving as educational and recreational areas. Many governments, non government organizations and scientists are also working with local inhabitants and private entrepreneurs to develop management strategies for biodiversity preservation. These strategies are aimed to ensure that the development projects are consistent with conservation objectives, thus minimizing environmental damage. The involvement of indigenous people and other key stakeholders in devising such strategies is a key to sustainable utilization of these resources. Creating appropriate environmental awareness and providing scientifically based information to citizen is also equally important to motivate them to protect the environment and spur them towards positive action. Promoting Sustainable Development Sustainable development has been defined as the ability to meet the needs of today’s generation without compromising the ability of future generations to meet their needs. Sustainable living does not deplete natural resources or biodiversity, rather it promotes its conservation. It succeeds only when governments, NGOs, scientists, industry and citizen 20 Biological Diversity use their knowledge of resilience and vulnerabilities of populations and ecosystems to meet economic needs, deal effectively with demands for resources and promote equitable benefit sharing. Over the years a series of national and international treaties and conventions have been initiated and laws enacted to protect biodiversity. Organizations like, the World Conservation Union (IUCN), the United Nations Development Program (UNDP), Global Environment Facility (GEF), United Nations Conference on Trade & Development (UNCTAD), World Bank, Convention on International Trade in Endangered Species of wild fauna & flora (CITES), United Nations Educational, Scientific & Cultural Organization (UNESCO), Secretariat of DIVERSITAS, etc. are involved in conserving the planet’s natural resources. The Man & Biosphere program of UNESCO was initiated in 1971 and has resulted in the study of major ecosystems and bioclimatic zones in the world and conservation of representative areas in form of Biosphere Reserves. Another important initiative is the ‘The Convention on Biological Diversity’ which has been ratified by about 180 countries of the world. Man & Biosphere (MAB) Program In 1968, UNESCO organized the ‘Biosphere Conference’ at Paris which recommended the setting up of an interdisciplinary international research program on environment, with focus on developing countries. As a result the ‘Man & Biosphere (MAB)’ Program was launched in 1971 to study the structure, functions and dynamics of various ecosystems and bioclimatic zones (like tropical, subtropical & temperate forest systems, grasslands, semiarid and arid areas, wetlands, coastal areas, islands and mountains) and humanenvironment inter-relationships (like effects of major engineering works, urban systems, pollution, interaction between environment & human population, pest management and fertilizer use, conservation of natural genetic materials, etc.). With better understanding of interactions within the ecosystems, the program switched over from a biocentric to an anthropocentric approach. It was realized through such studies that people were an integral part of the environment and their participation in natural resource management was crucial to protect all ecosystems. This also called for respecting the traditional wisdom of local communities in protecting and sustainably utilizing their natural resources. A natural consequence to this realization was introduction of the concept of Biosphere Reserves. These Biosphere Reserves are now a world wide network and form the backbone of MAB activities. The Biosphere Reserve Conference held in Seville, Spain in 1995 dwelt Biological Diversity 21 on Strategies and statutory framework for Biosphere Reserves. It emphasized on their role in conservation of biodiversity, its research & monitoring and in providing improved quality of life for local communities living in and around such areas. The Biosphere Reserve program, therefore, calls for establishing core zones, buffer zones and transition zones in each ecosystem with appropriate linkages, empowerment and participation of traditional societies for their management and protection by adopting sustainable livelihood practices. There are current 507 sites designated by UNESCO under the World Network of Biosphere Reserves in 108 countries. India has four UNESCO designated Biosphere Reserves and 10 similarly managed National Biosphere Reserves. The transition zones from the Shivalik ranges to mid Himalayan ranges in north western Himalayan region, extending from Punjab to parts of Himachal Pradesh and Jammu & Kashmir (especially the area of the Dhars) is still unrepresented.

Biosphere Reserves of India 22 Biological Diversity Convention on Biological Diversity (CBD) Much of the world’s biological wealth in concentrated in developing countries in the tropical areas. On the other hand, developed countries which possess financial & technical capabilities to add value to these resources and derive considerable economic benefits out of these endeavours, lie in colder latitudes. Not surprisingly, tropical countries like India, Malaysia & Brazil and those in Africa, are keen to ensure that they too get a fair share in the profits based on the use of their rich biological resources and traditional knowledge associated with their utilization. The Convention on Biological Diversity, for the first time, recognizes that all countries have a sovereign right on their natural resources. Thus, now if a new product is developed based on a resource obtained from a developing country, this can be done only through prior informed consent on the basis of an agreement which will include benefit sharing with the country of origin. The Convention on Biological Diversity further aims to: Conserve biological diversity Promote sustainable biological resources use of Promote fair & equitable sharing of benefits arising from use of genetic resources It encourages governments from various countries to conserve their ecosystems and natural habitats, identify and monitor biodiversity, promote technical & scientific cooperation, create public awareness and provide incentives to developing countries for conserving their natural resources. Further, the Convention has another important provision. The usual Intellectual Property Rights regime (as recognized by the World Trade Organization) guarantees economic benefits only to patent holders and not to holders of any publicly held knowledge which may have served as the foundation for the patented invention. The Story of SarpgandhA Sarpgandha (Rauvolfia serpentina) is a medicinal plant found in India which is traditionally used for treatment of snake bite, hypertension, schizophrenia and stomach disorders. A few decades ago in the pre CBD era a German Pharmaceutical Company realized that the plant was the source of an alkaloid, reserpine, which was useful in treatment of blood pressure, and patented the product. This development led to rapid, unchecked exploitation of wild populations of the plant. Subsequently, India banned the export of this plant, prompting the production of a synthetic substitute by the Pharmaceutical Industry. In the whole process India gained very little, other than some low value for raw plant material for a few years before it was exhausted due to over-exploitation. Under the CBD provisions, the Sarpgandha story will not be repeated. However, we will not reap the full benefits of the provisions of the Convention on Biological Diversity, unless initiatives to record traditional knowledge, promote indigenous research and develop capabilities for good management of information are taken up. One such initiative in this direction is the development of Traditional Knowledge Digital Library (TKDL). Another initiative is the preparation of People’s Biodiversity Registers (PBRs). Biological Diversity 23 However, the Convention on Biological Diversity provides for respecting traditional knowledge of local communities and sharing with them the benefits flowing out of commercial utilization of such knowledge. An important voluntary application of this provision has occurred in case of the tonic ‘Jeevani’, developed by scientists of Tropical Botanical Garden & Research Institute, Kerala where scientists learnt from two members of Kani tribal group that consuming the leaves of Trichopus zeylanicus, a commonly found herb in the forest, helped prevent fatigue. The institute developed the tonic with the help of a pharmaceutical company and shared the royalty with the local population. In contrast, a controversy arose due to granting of a patent by US Patent Office to a lotion made from turmeric for its wound healing properties. Since patents can be granted only for products and processes which are novel (new) and the wound healing properties of turmeric are in public knowledge in India since millennia, this patent was got revoked by the Indian government through the Council for Scientific & Industrial Research. The Biological Diversity Act Taking cognizance of the provisions of the Convention of Biological Diversity, and to deal with extensive pressure on our biological resources, India has enacted the Biological Diversity Act, 2002. The Act provides for conservation of biodiversity, besides facilitating access to biological resources in a sustainable manner. The Act is implemented through the National Biodiversity Authority at the Central Government level, the State Biodiversity Boards at the state government level and the Biodiversity Management Committees at the village/ town level. The National Biodiversity Authority is responsible for regulating access to biological diversity by foreigners and NRIs and ensures that the commercial benefit and intellectual property of the country is equitably shared amongst all stakeholders, especially local communities. The Act also provides for establishment of State Biodiversity Boards to facilitate implementation. Other major initiatives at the national level include, National Conservation Strategies & National and State Biodiversity Strategies & Action Plans, National Environment Policy and several other environmental laws. State Biodiversity Boards The State Biodiversity Boards are envisioned as statutory bodies under the Biological Diversity Act to facilitate conservation of biodiversity at the state level and to regulate commercial utilization of biological resources by industrial and commercial entities so that 24 Biological Diversity local communities get an adequate share of economic benefit arising from the use of these resources. Commercial bodies harvesting natural resources from an area for economic benefit would be required to take clearance from the State Biodiversity Board and deposit a collection fee. The State Biodiversity Boards are required to set up Biodiversity Management Committees at village & town level to ensure public participation in biodiversity conservation and sustainable utilization through decentralized planning. The Biodiversity Management Committees would keep a record of the natural resources and their utilization in areas within their jurisdiction. They would comprise representatives of the local body, school teachers, cultivators, medical practitioners and all other stakeholders whose livelihood depends upon local biological resources, and would play an important role in implementation of the Biological Diversity Act at the field level. The Biodiversity Management Committees are also entrusted to prepare Peoples’ Biodiversity Registers. Information about the local flora & fauna (both, wild & domesticated), its use and associated traditional knowledge will be recorded in these registers. This will ensure that the natural resources of our country are protected with the active participation of people. The making of a village PBR (Peoples’ Biodiversity Register) Peoples’ Biodiversity Registers is a documentary record of the available bioresources in an area found both, in the farms and in the wild, and the traditional knowledge associated with these resources like, how plants & animals or their parts are used for food, medicine, livelihoods or other uses by people, method of their cultivation/rearing and sustainable harvesting and their role in local customs, rituals & beliefs. On April 9, 1997, in the small village of Puttuvam in Kerala, an old farmer handed over a register to a young child containing all such information pertaining to the village. The child in turn, handed it over to the village Sarpanch (head) for safe custody in the interest of the community and future generations. This register had been prepared by the educated people in the village who organized exhibitions of all plants & domesticated animals in/around their village & surveyed fields and nearby ponds & forest areas and made records of how various resources were used locally. They sought information from the village elders, craftsmen, fishermen and folk artists on traditional crops, land races & the uses of many plants and animals and even honoured the farmers & women who had protected traditional varieties by cultivating them. They sought expert help wherever required but did all the recording themselves to ensure that nothing was left out. As a result, besides many cultivars of crops especially rice, they recorded 366 species of plants, 32 spp. of mangroves, 93 spp. of birds, 14 wild mammals and 30 kinds of fish, molluscs, etc. from a small area. They recorded all prevalent common names, as well as, scientific names where possible. Rare plants and animals were also recorded. Care was, however, taken to record specific information in a way that it could not be misused. A declaration of ownership was then made to prevent outsiders from filing patents from their bioresources. This register is expected to prevent biopiracy and help locals to ensure benefit sharing if any of it is commercially utilized. Every village can make such registers and protect its biodiversity from biopiracy. This is suggested under the Biological Diversity Act also. All we need are informed enthusiastic volunteers.
