Faster biodiversity decline in protected areas

A recent study by the Natural History Museum (NHM), London, has unveiled a troubling trend: biodiversity is vanishing more rapidly within designated protected areas than in surrounding unprotected regions. This alarming finding challenges the efficacy of current conservation strategies, suggesting that simply designating more areas as protected is insufficient to safeguard biodiversity. The study serves as a stark reminder to policymakers and conservationists that effective protection requires more than just drawing boundaries on a map.

  • Biodiversity: Earth’s Life Support System
    • The intricate web of life on Earth, encompassing genetic, species, and ecosystem diversity.
    • Of the estimated 8-20 million species, only a fraction (around 2 million) have been formally identified.
  • A Planet in Peril: Declining Biodiversity
    • Biodiversity Intactness Index (BII): A measure of the remaining natural biodiversity in a region.
    • Global Decline: The BII has fallen by 1.88% globally between 2000 and 2020, indicating a significant loss of biodiversity.
  • The Plight of Critical Biodiversity Areas (CBAs)
    • CBAs are vital ecosystems, such as wetlands, that support a rich array of species.

  • Flora’s Diversity: The Indian subcontinent supports a diverse flora, comprising over 55,048 species, with 12,095 endemic plants.
  • A Network of Protected Areas: India’s extensive network of 106 National Parks and 572 Wildlife Sanctuaries covers 1.36% and 3.86% of the total land area, respectively.
  • Gujarat’s Conservation Commitment: Gujarat leads the way in protected area coverage, with 17,098 square kilometers designated for conservation, accounting for 8.72% of its state area.
  • Small States, Big Conservation Impact: Sikkim, Chandigarh, Ladakh, and Goa, despite their smaller sizes, have made significant strides in conservation, with over 20% of their territories under protection.
  • A Growing Conservation Network: Between 2000 and 2023, India witnessed a substantial increase in the number and area of protected areas, reflecting a growing commitment to biodiversity conservation.
  • Safeguarding Life’s Support Systems: Protected areas serve as havens for diverse species by preserving their critical habitats. These natural sanctuaries ensure the survival of countless organisms and maintain the delicate balance of ecosystems.
  • Preserving Earth’s Biodiversity Hotspots: Many protected areas are designated as biodiversity hotspots, harboring a unique and irreplaceable assemblage of species. These ecological treasure troves are vital for the planet’s biodiversity.
  • Nurturing Genetic Diversity: By safeguarding a wide range of species and their genetic variations, protected areas contribute to the genetic diversity of ecosystems. This genetic diversity is essential for the adaptability and resilience of species in the face of environmental change.
  • A Refuge for Endangered Species: Protected areas provide a lifeline for endangered and threatened species, offering them a safe haven to recover and thrive. By maintaining natural habitats, these areas help to bolster dwindling populations and prevent extinction.
  • A Laboratory for Science: Protected areas offer invaluable opportunities for scientific research and monitoring. Scientists can study ecological processes, understand the intricate interactions between species, and develop effective conservation strategies.
