Biodiversity Conservation

Definition

Biodiversity conservation refers to the protection, preservation, and management of biodiversity and natural resources. It primarily employs two strategies: In-Situ Conservation and Ex-Situ Conservation, each with distinct approaches and applications.

In-Situ Conservation

In-situ conservation involves the conservation of genetic resources within natural or human-made ecosystems where they occur naturally. It is considered the most appropriate method for conserving wild species, as it allows species to continue evolving in their natural environment.

Key Facts

• Location: Within the natural habitat or ecosystem.
• Focus: Entire ecosystems and the species within them.
• Examples in India:
  • National Parks: Areas dedicated to the conservation of wildlife and their environment, where human activities like grazing and forestry are prohibited. Established under the Wildlife Protection Act, 1972. India has 106 National Parks (as of 2023).
  • Wildlife Sanctuaries: Areas where wildlife and their habitats are protected, allowing some human activities like regulated tourism. Also established under the Wildlife Protection Act, 1972. India has 567 Wildlife Sanctuaries (as of 2023).
  • Biosphere Reserves: Internationally recognized areas designated by UNESCO under its Man and the Biosphere (MAB) Programme. They aim to achieve sustainable development by reconciling biodiversity conservation with its sustainable use. India has 18 Biosphere Reserves, with 12 included in the World Network of Biosphere Reserves.
  • Sacred Groves: Patches of forest or natural vegetation protected by local communities due to religious beliefs, representing traditional in-situ conservation.
  • Project Tiger (launched 1973) and Project Elephant (launched 1992) are prime examples of in-situ conservation efforts.
• Advantages: Preserves evolutionary processes, maintains ecological interactions, cost-effective for large areas, allows for natural adaptation.

Ex-Situ Conservation

Ex-situ conservation involves the conservation of components of biological diversity outside their natural habitats. This approach is crucial for species facing immediate threats in the wild or for maintaining genetic diversity that might otherwise be lost.

Key Facts

• Location: Outside the natural habitat, in controlled environments.
• Focus: Individual species, genetic material, or specific populations.
• Examples:
  • Botanical Gardens: Collections of living plants maintained for scientific research, conservation, display, and education. India has many, like the Acharya Jagadish Chandra Bose Indian Botanic Garden in Howrah.
  • Zoological Parks (Zoos): Facilities where wild animals are housed within enclosures, cared for, displayed to the public, and often used for captive breeding programs to reintroduce endangered species into the wild. Regulated by the Central Zoo Authority (CZA), established in 1992 under the Wildlife Protection Act, 1972.
  • Gene Banks: Facilities that store genetic material of plants and animals, including seeds, sperm, eggs, and tissue samples. The National Bureau of Plant Genetic Resources (NBPGR) in New Delhi is a prominent example in India.
  • Seed Banks: Specialized gene banks that store seeds, often at low temperatures and humidity, to preserve genetic diversity for long periods. The Svalbard Global Seed Vault in Norway, opened in 2008, is the world's largest and most secure seed bank.
  • Cryopreservation: A technique involving the storage of biological material (seeds, pollen, tissue, sperm, eggs, embryos) at ultra-low temperatures (e.g., in liquid nitrogen at -196°C) to maintain viability for extended periods.
  • Tissue Culture: A method of growing cells, tissues, or organs in an artificial nutrient medium, used for rapid propagation of plants and conservation of rare species.
• Advantages: Protects species from immediate threats, allows for intensive research, facilitates captive breeding and reintroduction, preserves genetic material for future use.

Exam Angle

UPSC often asks to differentiate between these two methods, provide examples, or analyze their effectiveness in specific contexts. Understanding the legal frameworks (e.g., WPA 1972) and key institutions (e.g., CZA, NBPGR) is crucial. Questions may also link these concepts to international conventions like the Convention on Biological Diversity (CBD).

Community Conservation refers to the protection and management of natural resources and biodiversity by local communities, often with government support. It emphasizes the crucial role of people, especially indigenous and tribal communities, in sustainable resource management, recognizing their traditional knowledge and dependence on local ecosystems. This approach aligns with Elinor Ostrom's principles for sustainable management of common-pool resources, which include clearly defined boundaries, participatory rule modification, monitoring, graduated sanctions, and local institutional autonomy (40,41).

In India, Common Property Resources (CPRs) are central to community conservation. The National Sample Survey Organisation (NSSO) in its 1998 survey ('Common Property Resources in India', 54th Round) first defined CPRs as areas collectively used by villagers for fodder, fuel, water, and livelihoods, estimating they comprised approximately 15% of India’s geographical area (32). By the 2011 Census, India's common land was estimated at 6.6 crore hectares, forming biodiversity-rich ecosystems (33). These CPRs provide 34 different services, supporting the livelihoods of approximately 35 crore rural people by supplying food, fodder, fuelwood, and non-material benefits like clean air and water purification (34,35). They generate an economic dividend of USD 9.05 crore per year and contribute significantly to SDGs like poverty reduction (SDG 1) and sustainable livelihoods (SDG 8) (34,35).

However, CPRs face degradation due to encroachment and misuse, with degraded land expanding according to ISRO’s Desertification and Land Degradation Atlas 2021 (36, 38). To counter this, community-driven models, often supported by NGOs and Krishi Vigyan Kendras (KVKs), are vital. For instance, community-run seed banks in Jhabua, Madhya Pradesh, help tribal farmers re-adopt traditional and organic farming practices, reducing dependence on external seed markets (56). Tribal communities, constituting 8.9% of India's population and residing predominantly in biodiverse regions, possess valuable traditional knowledge, with the economic value of natural services from India's forests estimated at ₹128 trillion per year (52,53,54).

Exam Angle: For Prelims, focus on definitions (CPRs, JFM, Conservation/Community Reserves), key statistics (15% land, 6.6 crore hectares, USD 9.05 crore/year), specific acts (Wildlife Protection Act), and names (NSSO, ISRO, Elinor Ostrom). For Mains, analyze the importance of community participation, the challenges faced by CPRs, the role of traditional knowledge, and the socio-economic benefits of community conservation.

Coastal and marine conservation encompasses the protection, preservation, and sustainable management of coastal ecosystems, marine environments, and their diverse biodiversity. These critical habitats, including coral reefs, mangroves, and estuaries, are vital for maintaining ecological balance, providing essential ecosystem services, and supporting human livelihoods. Coral reefs, for instance, host immense biodiversity, including approximately 4,000 species of fish and 800 species of hard corals, while also acting as natural buffers against waves, floods, and storms, preventing erosion and property damage.

However, these ecosystems face significant threats from anthropogenic activities. Ocean pollution is a complex issue, comprising toxic metals, manufactured chemicals, plastics, urban and industrial wastes, petroleum, pesticides, fertilisers, pharmaceutical chemicals, sewage, and agricultural runoff. Microplastics, defined as plastic particles less than 5mm in diameter, are particularly concerning, contributing to over 80% of ocean debris and entering the marine food chain, posing risks to marine organisms and human health. Climate change-induced marine heatwaves are also devastating; the Global Biodiversity Outlook 5 (GBO-5) 2020 reported that over 60 percent of the world’s coral reefs are under threat, with the 2016 marine heatwaves causing severe bleaching of Australia's Great Barrier Reef and mangrove die-offs in the Gulf of Carpentaria. Furthermore, the proportion of fish stocks fished sustainably has decreased by 5 percent since 2010.

India has implemented several legal frameworks for conservation. Corals are protected under Schedule I of the Wild Life Protection Act, 1972. The Environment Protection Act, 1986 (EPA), and the Coastal Regulation Zone (CRZ) Notification of 1991, issued under the EPA, regulate activities in coastal areas. Marine Protected Areas (MPAs) are also designated for conservation. Globally, the 1982 United Nations Convention on the Law of the Sea (UNCLOS) mandates states to control ocean pollution, while MARPOL (International Convention for the Prevention of Pollution from Ships), established in 1973 and 1978 and enforced internationally in 1983, specifically targets vessel pollution, especially oil.

Conservation efforts include the International Blue Carbon Initiative, focused on mitigating climate change through coastal and marine ecosystem restoration, and the 'Magical mangroves: join the movement' campaign. The Blue Nature Alliance is a global partnership advancing Ocean Conservation Areas. India's MISHTI (Mangrove Initiative for Shoreline Habitats & Tangible Incomes), launched in 2023, aims to restore mangroves, generate employment (estimated 22.8 million person-days), and create carbon sinks (estimated 4.5 million tonnes). The O-STORMS project (Ocean Services, Technology, Observations, Resources, Modelling, and Science) enhances ocean understanding and data-driven management. These initiatives are crucial for achieving SDG 14: "Conserve and sustainably use the oceans, seas, and marine resources for sustainable development."

For Prelims, specific acts (WPA 1972, EPA 1986, CRZ 1991), international conventions (UNCLOS, MARPOL dates), and initiatives (MISHTI, Blue Carbon, O-STORMS) are potential MCQ traps. Mains questions might focus on the causes and consequences of marine degradation, the effectiveness of conservation measures, or policy recommendations for sustainable ocean management.

Definition

International Biodiversity Agreements are multilateral environmental agreements (MEAs) designed to address the global crisis of biodiversity loss. These frameworks provide legal and policy instruments for countries to cooperate on conservation, sustainable use, and equitable sharing of benefits derived from biological resources. The most prominent among these is the Convention on Biological Diversity (CBD).

Key Facts

• Convention on Biological Diversity (CBD):
  • Adopted at the Earth Summit in Rio de Janeiro in 1992, it entered into force on 29 December 1993.
  • It is a legally binding international treaty with nearly universal participation (196 Parties).
  • Three main objectives:
    1. The conservation of biological diversity.
    2. The sustainable use of its components.
    3. The fair and equitable sharing of the benefits arising out of the utilization of genetic resources.
  • The Conference of the Parties (COP) is the governing body of the CBD, meeting periodically to review progress and make decisions.
  • The CBD Secretariat is located in Montreal, Canada.
• Cartagena Protocol on Biosafety:
  • Adopted in January 2000 and entered into force in September 2003.
  • Focuses on the safe handling, transport, and use of Living Modified Organisms (LMOs) resulting from modern biotechnology that may have adverse effects on biodiversity, also taking into account risks to human health.
  • It establishes an Advance Informed Agreement (AIA) procedure for LMOs intended for intentional introduction into the environment.
• Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization (ABS):
  • Adopted in October 2010 in Nagoya, Japan, and entered into force on 12 October 2014.
  • Provides a transparent legal framework for the effective implementation of the third objective of the CBD: the fair and equitable sharing of benefits arising from the utilization of genetic resources.
  • It addresses access to genetic resources and the sharing of benefits, including those associated with traditional knowledge.
• Aichi Biodiversity Targets:
  • Part of the CBD's Strategic Plan for Biodiversity 2011-2020, adopted at COP 10 in 2010.
  • Comprised 20 ambitious, yet achievable, targets organized under five strategic goals, aiming to halt biodiversity loss.
  • Despite efforts, most Aichi Targets were not fully met by the 2020 deadline.
• Kunming-Montreal Global Biodiversity Framework (GBF):
  • Adopted at COP15 in Montreal in December 2022.
  • A landmark agreement to guide global action on biodiversity through 2030 and beyond.
  • It includes a vision for 2050 of “living in harmony with nature” and a mission for 2030 to halt and reverse biodiversity loss.

Mechanism

The CBD operates through national implementation by its Parties, who are required to develop national biodiversity strategies and action plans (NBSAPs). These plans translate the CBD's objectives into concrete national actions. Parties report on their implementation progress to the COP. The protocols (Cartagena and Nagoya) provide specific rules and procedures for their respective areas, requiring signatory nations to establish legal and administrative frameworks to regulate LMOs and ABS, respectively. The GBF sets new global targets and goals, urging countries to update their NBSAPs to align with these ambitious new commitments.

Exam Angle

For UPSC, understanding the three core objectives of the CBD is critical. Differentiating between the Cartagena Protocol's focus on biosafety (LMOs) and the Nagoya Protocol's focus on Access and Benefit Sharing (ABS) is crucial. The shift from the Aichi Targets to the Kunming-Montreal Global Biodiversity Framework (GBF), including its 2030 mission and 2050 vision, along with key targets like the '30x30' target, is a high-priority area for both Prelims and Mains.

Species Recovery Programmes are national initiatives in India designed to protect and revive populations of critically endangered, endangered, and vulnerable species, along with their crucial habitats. These programs often involve a multi-pronged approach encompassing habitat restoration, anti-poaching measures, scientific monitoring, community participation, and policy interventions.

Key Facts:

• Project Tiger (1973): Launched on April 1, 1973, it is one of the most successful conservation initiatives globally. Administered by the National Tiger Conservation Authority (NTCA) under the Ministry of Environment, Forest and Climate Change (MoEFCC), it aims to ensure a viable population of Bengal tigers in their natural habitats. India currently hosts over 70% of the world's wild tiger population, with 54 Tiger Reserves covering 75,796 sq km (as of 2023).
• Project Elephant (1992): Launched in 1992 as a Centrally Sponsored Scheme, it aims to protect elephants, their habitat, and migration corridors. It also addresses human-elephant conflict and promotes the welfare of captive elephants. The Monitoring the Illegal Killing of Elephants (MIKE) program, associated with CITES, is implemented in India through Project Elephant.
• Project Snow Leopard (2009): Launched in 2009, this project focuses on conserving snow leopards and their high-altitude ecosystems in five Himalayan states/UTs: Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Sikkim, and Arunachal Pradesh.
• Project Cheetah (2022): India's ambitious reintroduction program, launched in September 2022, brought cheetahs from Namibia and South Africa to Kuno National Park, Madhya Pradesh, aiming to restore the species that went extinct in India in 1952.
• Indian Rhino Vision 2020 (IRV 2020): Launched in 2005, this program aimed to achieve a wild population of at least 3,000 greater one-horned rhinos spread over seven protected areas in Assam by 2020. It involved translocations to expand their range.
• Vulture Conservation: India launched a Vulture Conservation Action Plan (VCAP) in 2006, updated in 2020, primarily to address the drastic decline in vulture populations due to the veterinary drug diclofenac. It focuses on banning harmful drugs, establishing Vulture Safe Zones, and captive breeding.
• Recovery Programme for Critically Endangered Species: Initiated in 2012 under the Centrally Sponsored Scheme 'Integrated Development of Wildlife Habitats', this umbrella program supports the recovery of 22 critically endangered species, including the Great Indian Bustard, Manipur Brow-antlered Deer, Dugong, and various marine turtles and crocodiles.

How It Works/Mechanism: These programmes typically operate as Centrally Sponsored Schemes, with funding shared between the central and state governments. They involve establishing protected areas (National Parks, Wildlife Sanctuaries, Tiger Reserves, Elephant Reserves), implementing anti-poaching strategies, habitat improvement (e.g., grassland development, waterhole creation), scientific research and monitoring (e.g., camera trapping, radio-tagging), community engagement for reducing human-wildlife conflict, and sometimes captive breeding and reintroduction/translocation efforts.

Exam Angle: Prelims: Focus on launch years, objectives, key implementing agencies (e.g., NTCA for Project Tiger), specific species covered under different projects, associated international programs (e.g., MIKE, CITES), and major locations (e.g., Kuno for Cheetah, Kaziranga for Rhino). Be aware of numerical data like the number of tiger reserves or rhino population figures. MCQ traps might involve mixing up launch years or objectives of different projects. Mains: Analyze the effectiveness of these programs, challenges faced (human-wildlife conflict, habitat fragmentation, climate change, funding), the role of community participation, and the balance between conservation and development. Essay hooks could include topics like 'India's conservation journey: successes, failures, and the way forward' or 'The role of flagship species in broader ecosystem conservation'.

These are protected areas established on private or community-owned land. They were introduced by the 2002 amendment to the Wildlife Protection Act. The goal is to involve local people in conservation. The Chief Wildlife Warden manages them. While hunting is banned, locals keep their traditional rights to forest produce and farming. Example: Keshopur-Chamb Community Reserve in Punjab.

These are protected areas established on private or community-owned land. They were introduced through the 2002 amendment to the Wildlife Protection Act. The management is done by a Community Reserve Management Committee. Once notified, hunting is banned, but traditional agricultural practices and collection of non-timber forest produce are allowed. The Chief Wildlife Warden of the State acts as the governing authority. An example is the Keshopur-Chamb Community Reserve in Punjab.

Conservation Reserves are government-owned lands that connect protected areas like National Parks and Sanctuaries. They act as 'buffer zones' or corridors for animal movement. They were also introduced by the 2002 amendment. The local community is involved in the management through a committee. This helps reduce conflict between humans and wildlife near forest edges. An example is the Beas River Conservation Reserve in Punjab.

Community Reserves are protected areas that act as buffer zones between established national parks and wildlife sanctuaries. They are usually created on community-owned or private land. The government notifies these areas to protect biodiversity while respecting local traditions. Once notified, hunting is banned. However, the law allows locals to collect non-timber forest products and practice traditional farming. This ensures that conservation does not destroy the livelihoods of the people living there. Example: The Gogabeel Community Reserve in Bihar.

A Community Reserve is an area notified by the government on private or community-owned land. It is created when local people agree to protect the wildlife and their habitats. Once notified, the Chief Wildlife Warden becomes the governing authority. Inside these reserves, hunting is strictly prohibited. However, the local people are allowed to continue their traditional practices. They can collect non-timber forest produce like fruits or honey. They can also continue traditional farming. This balance helps protect nature without hurting the local economy.

A Community Reserve is a category of protected area introduced in 2002. It acts as a buffer zone between established National Parks and human settlements. These areas are usually private or community-owned land. Once the government notifies it, the Chief Wildlife Warden becomes the governing authority. While hunting is strictly banned here, people are often allowed to continue traditional practices and collect non-timber forest produce. This balances conservation with the needs of local communities.

The Miyawaki method is a unique technique to create 'mini-forests' in very small urban spaces. It involves planting many different types of native trees close together. This high density creates a self-sustaining ecosystem very quickly. These forests grow 10 times faster and are 30 times denser than traditional plantations. They are excellent for reducing noise pollution and absorbing carbon in crowded cities. Example: Many Indian cities like Mumbai and Chennai are now using this to increase green cover.

The Miyawaki method is a Japanese technique for growing forests quickly. It involves planting many different types of native trees very close together. This makes the plants compete for sunlight and grow much faster than usual. This method is used to create 'mini forests' in urban areas or cities. These small forests help lower the temperature and reduce air pollution. They become self-sustaining after just two or three years of care. It is a popular way to increase green cover in crowded Indian cities.

The main difference is the level of restriction. In a National Park, no human activity is allowed at all. You cannot own land or graze animals there. In a Wildlife Sanctuary, some human rights are allowed. For example, local people may be allowed to graze their cattle or collect firewood if it does not harm the animals. A Sanctuary can be upgraded to a National Park, but a National Park is usually not downgraded to a Sanctuary. Both are declared by the State Government through a notification.

This method protects species in their original, natural environment. It is the most effective way to maintain biological diversity. It allows species to continue evolving in the wild. Key examples include National Parks (total protection) and Wildlife Sanctuaries (limited human activity). It also includes Sacred Groves, which are forest patches protected by local communities due to religious beliefs.

This is a Japanese technique for building dense, native forests in short periods. It is used to create mini-forests in urban areas. The method involves planting two to four types of indigenous trees within every square metre. These plants grow very fast because they compete for sunlight. It helps in increasing biodiversity and lowering temperatures in cities. UPSC asked about this method in the 2022 Prelims exam.

This is the main law for protecting plants and animal species in India. It provides the legal framework for establishing National Parks and Sanctuaries. The Act has different schedules that give different levels of protection to animals. For example, animals in Schedule I receive the highest protection and the harshest penalties for hunting. This Act also prohibits the hunting of any wild animal specified in the schedules. It is the foundation for all conservation efforts in the country.

These are protected areas introduced by the Wildlife Protection (Amendment) Act of 2002. They are usually created on land owned by communities or individuals. The goal is to protect biodiversity while respecting local traditions. Once notified, the land use cannot be easily changed. However, traditional rights are often protected. An example is the Khonoma Nature Conservation and Tragopan Sanctuary in Nagaland, where the local community protects the forest and its wildlife.

REDD+ stands for Reducing Emissions from Deforestation and Forest Degradation. The '+' sign includes the role of conservation and sustainable management. This program creates a financial value for the carbon stored in forests. It offers incentives for developing countries to reduce emissions from forested lands. For example, a village might receive funds for protecting a forest instead of cutting it down for timber. This helps fight global climate change by keeping carbon locked in trees.

The Miyawaki method is a technique to create mini-forests in urban areas. It was developed by a Japanese botanist named Akira Miyawaki. In this method, many native tree species are planted very close to each other. This high density makes the plants grow faster as they compete for sunlight. Within two to three years, the area becomes a dense, multi-layered forest. It helps in reducing urban heat, improving air quality, and supporting local biodiversity in crowded cities.

In-situ conservation means 'on-site' protection. It involves protecting a species in its natural home, like a Tiger in a National Park. Ex-situ conservation means 'off-site' protection. It involves moving an endangered species to a new, controlled location. This is done when the natural habitat is too dangerous or destroyed. Examples of Ex-situ include Gene Banks or Zoos where animals are bred to increase their population safely before being released back into the wild.

Developed by Japanese botanist Akira Miyawaki, this method creates dense, native forests. Trees are planted very close to each other (about 3 per square meter). This forces them to grow upwards for sunlight, making them grow 10 times faster than usual. These forests become 30 times denser and are great for urban areas with limited space.

The Man and the Biosphere (MAB) is an international program. It provides a scientific basis for improving the relationship between people and nature. It recognizes certain reserves globally for their ecological value. Example: The Sunderbans is recognized by MAB because of its unique mangrove biodiversity and global importance.

NTFP refers to all biological materials derived from forests except for timber (wood). This includes products like wild edible plants, medicinal herbs, honey, wax, and resins. These products are crucial for the livelihood of tribal and forest-dwelling communities. In many protected areas, collecting NTFP is a legally recognized right. For example, many villagers depend on collecting 'Tendu' leaves to make local products, which provides them with a steady income without destroying trees.

Biosphere Reserves use a three-tier structure. The Core Zone is the innermost part with no human entry. The Buffer Zone allows controlled activities like environmental education. The Transition Zone is the outer part where sustainable farming happens. Example: In Nilgiri, the core includes Silent Valley, while local tribes live in the transition area.

This is the core philosophy of Biosphere Reserves. It means using natural resources today without destroying them for future generations. It involves local communities in conservation efforts. Example: Encouraging local tribes to collect honey or herbs without cutting down trees helps them earn money while keeping the forest safe.
