• Climate Change Mitigation and Adaptation: Biodiversity plays a vital role in India's climate change strategies.
  • Forests, which cover about 21.67% of India's geographical area, act as carbon sinks, sequestering about 7% of India's total GHG emissions.

What are the Efforts Related to Biodiversity Conservation in India?

• About: India is tremendously rich in species and ecosystem diversity. Over 1,03,258 species of fauna and 55,048 species of flora have been documented in the 10 biogeographic zones of the country.
  • Considering floral diversity, out of the 55,048 known plant species in India, 12,095 are endemic.
• Constitutional and Legal Provisions:
  • Article 48A directs the state to protect and improve the environment and safeguard forests and wildlife, while Article 51A(g) makes it a fundamental duty of citizens to protect and improve the natural environment, including forests, lakes, rivers, and wildlife.
  • The Environment (Protection) Act, 1986 empowers the central government to manage pollution, hazardous substances, and industrial activities, set emission standards, and coordinate with state authorities, indirectly promoting biodiversity conservation.
  • The Biological Diversity Act, 2002 was enacted for conservation of biological resources, managing its sustainable use and enabling fair and equitable sharing benefits arising out of the use and knowledge of biological resources with the local communities.
  • In the landmark case of Animal Welfare Board of India vs A. Nagaraja & Ors (2014), the Supreme Court recognized that every species has an inherent right to live and shall be protected by law, emphasizing the constitutional mandate under Article 21 of the Constitution.
  • In the Mk Ranjit Singh vs. Union of India case, the Supreme Court affirmed the right to a healthy environment and protection from climate change, balancing species conservation with climate action.
• Major Committees Related to Biodiversity Conservation:
  • Madhav Gadgil Committee Recommendations:
    • 64% of the area under Ecologically Sensitive Area (ESA).
    • No new large dams or polluting industries in sensitive zones.
    • Existing industries to switch to zero pollution by 2016.
    • Establishment of Western Ghats Ecology Authority with statutory powers.
  • Kasturirangan Committee Recommendations:
    • 37% of Western Ghats as ESA.
    • Ban on mining, quarrying, and new thermal power projects.
    • Restrictions on hydropower projects and construction.

What are the Key Threats to Biodiversity in India?

• Habitat Loss- The Vanishing Wilderness: India's rapid urbanization and agricultural expansion are causing severe habitat loss.
  • Between 2001 and 2020, India lost 1.93 million hectares of tree cover, equivalent to a 5.2% decrease since 2000.
  • The fragmentation of forests, such as in the Western Ghats, threatens endemic species like the lion-tailed macaque.
  • Recent projects like the Mumbai-Ahmedabad bullet train, cutting through Thane Creek Flamingo Sanctuary, exemplify how development often comes at the cost of critical habitats.
• Invasive Species-The Silent Invaders: Non-native species are wreaking havoc on India's ecosystems.
  • India’s biodiverse ecosystems are threatened by a variety of alien plants like Lantana camara, Parthenium hysterophorous, Prosopis juliflora, etc, introduced during British colonization.
    • Lantana alone has pervasively invaded 44% of India’s forests.
  • In the Andaman Islands, the invasive giant African snail threatens local biodiversity.
  • The recent spread of Fall Armyworm has affected maize crops across various Indian states since 2018, highlighting the economic impact of invasive species.
• Climate Change- The Looming Threat: Climate change is altering habitats and migration patterns across India.
  • Mangrove forests like Sundarbans are facing the “triple threat” of sea-level rise, lack of mud and squeezed habitats.
  • In the Himalayas, warming temperatures are pushing species to higher altitudes, threatening high-altitude specialists like the snow leopard.
  • India's coral reefs, covering about 5,790 sq km, face multiple threats due to climate change.
    • The average live coral cover in Gulf of Mannar, one of the major coral reef areas in India, dropped from 37% in 2005 to 27.3% in 2021.
• Human-Wildlife Conflict- The Uneasy Coexistence: As human settlements expand, conflicts with wildlife intensify.
  • India reports over 500 people and 100 elephant deaths due to human-elephants in a year.
  • The recent case of a tiger being relocated after human conflict in the Ranthambore reserve highlights the ongoing challenge.
• Genetic Erosion-The Shrinking Gene Pool: India's rich agrobiodiversity is under threat from modern agricultural practices.
  • Many farmers have shifted to modern hybrid varieties, leading to the loss of traditional crop varieties.
  • The rice varieties in India have declined from 110,000 in the 1970s to about 6,000 today.
  • This erosion not only impacts food security but also reduces resilience to pests and climate change.
• Pollution: Pollution in various forms is severely impacting biodiversity. The Yamuna river, supporting over 50 fish species, is now biologically dead for a 22 km stretch in Delhi due to industrial effluents.
  • Microplastic pollution affects many fish species in the River Ganga.
  • Light pollution in coastal areas disorients nesting sea turtles.
• Policy Implementation-The Execution Challenge: While India has robust environmental laws, their implementation often falls short.
  • The recent controversy over environmental clearance for the Etalin Hydroelectric Project in Arunachal Pradesh (rejected in its present form) highlights the gaps in policy implementation.
• Urban Biodiversity Loss-The Concrete Jungle Effect: Rapid urbanization is decimating urban ecosystems.
  • India has lost nearly one-third of its natural wetlands to urbanization, agricultural expansion and pollution over the last four decades.
  • The decline of house sparrows in cities (over 80% in some areas) exemplifies the impact on common species.

What Strategies Can Be Implemented to Improve Biodiversity Conservation in India?

• Ecosystem-based Management: India should shift from species-centric to ecosystem-based conservation.
  • This involves identifying and protecting entire ecological networks, not just isolated protected areas.
  • For example, the 2018 initiative of declaring 438.904 square kilometers of the area around the Mudumalai Tiger Reserve (MTR) in the Nilgiris as an eco-sensitive zone (ESZ) is a step in this direction.
  • More better implementation would involve:
    • Integrating mapping into land-use planning at state and district levels
    • Providing incentives to local communities for maintaining these corridors
• Community-led Conservation: Involving local communities in conservation efforts has shown remarkable success.
  • The Van Panchayats in Uttarakhand demonstrate the potential of community-led conservation.
    • A former Chambal dacoit has become a 'Cheetah Mitra,' now raising awareness about cheetahs in Kuno, Sheopur.
  • Pamela and Anil Malhotra, a couple from Kerala, have created an inspiring example of private conservation efforts in India.
    • In 1991, they purchased 55 acres of abandoned land in Kodagu district, Karnataka, which had been degraded due to human activities.
    • Over three decades, they transformed this barren land into a lush, 300-acre private wildlife sanctuary named SAI (Save Animals Initiative) Sanctuary.
  • To scale this approach:
    • Strengthen and expand Joint Forest Management Committees
    • Provide legal recognition and support to Community Conserved Areas
    • Develop capacity-building programs for local communities in conservation techniques
