Subject: Biodiversity Conservation

  • India’s next conservation challenge lies beyond protected areas

    Why in the News

    An argument is being made that India’s conservation model, centered on isolated protected areas, is no longer sufficient. As development corridors fragment habitats, the next challenge is protecting connectivity through ecological corridors and area-based measures outside formal parks, in line with global biodiversity commitments.

    What is Protected-Area-Only Conservation Model?

    1. The Protected-Area-Only (PA-only) model is a traditional conservation strategy focused on creating and managing geographically defined zones such as national parks and nature reserves where human activity is strictly limited or prohibited to preserve biodiversity.
    2. Key elements include strict legal boundaries, top-down enforcement, and the exclusion of everyday resource extraction.

    Core Characteristics

    1. Spatial segregation: Separates nature preservation zones from human-dominated landscapes like farms or cities.
    2. Strict regulation: Limits or bans resource use, hunting, grazing, and permanent human settlement inside borders.
    3. Top-down control: Relies heavily on government oversight, rangers, and legal penalties to prevent habitat damage

    What are Other Effective Area-based Conservation Measures (OECMs)?

    1. Meaning: Other Effective Area-based Conservation Measures (OECMs) are areas outside formal protected areas that still deliver long-term biodiversity conservation.
    2. Difference from protected areas: They are not designated national parks or sanctuaries, but community lands, corridors or managed areas that sustain species.
    3. Global basis: OECMs are recognised under the Convention on Biological Diversity (CBD) as a route to expand effective conservation area.

    Why is the protected-area-only model insufficient?

    1. Habitat fragmentation: Infrastructure such as the Delhi-Dehradun Economic Corridor cuts through and isolates wildlife habitats.
    2. Island effect: Isolated parks trap populations, reducing genetic exchange and long-term viability.
    3. Corridor need: Landscapes such as Pench-Seoni show that connectivity between reserves is as vital as the reserves themselves.

    What must the new approach include?

    1. Ecological corridors: Legally recognised corridors linking protected areas would let species move and populations mix.
    2. National Conservation Estate: A wider conservation estate would bring corridors and OECMs into a coherent framework.
    3. CBD alignment: Meeting India’s biodiversity-area commitments under the CBD requires counting effective conservation beyond parks.

    Conclusion

    Conservation confined to isolated protected areas cannot survive large-scale habitat fragmentation. The central need is connectivity, through ecological corridors, OECMs and a National Conservation Estate. Aligning this with CBD commitments is how India can protect biodiversity beyond park boundaries.

    Landscape-Based Conservation

    Definition:
    Landscape-based conservation is an integrated approach that conserves biodiversity, ecosystems, and ecological connectivity across entire landscapes, including Protected Areas, forests, farmlands, rivers, wildlife corridors, and human settlements, while balancing conservation with sustainable livelihoods.

    Key Features

    1. Conserves entire ecosystems, not just isolated Protected Areas.
    2. Maintains ecological connectivity through wildlife corridors.
    3. Integrates local communities into conservation.
    4. Promotes sustainable land-use in agriculture, forestry, and infrastructure.
    5. Improves climate resilience by enabling species movement and adaptation.

    Why is it needed?

    1. Wildlife frequently moves outside Protected Areas.
    2. Prevents habitat fragmentation.
    3. Addresses climate change by allowing range shifts.
    4. Balances conservation with development and livelihoods.

    Examples

    1. Western Ghats Landscape: Eco-Sensitive Areas and corridor-based conservation.
    2. Nilgiri Biosphere Reserve: Connects Mudumalai, Bandipur, Nagarhole, Wayanad, and Sathyamangalam.
    3. Kaziranga-Karbi Anglong Landscape: Critical elephant and rhino corridor.
    4. Terai Arc Landscape (India-Nepal): Cross-border conservation for tigers, elephants, and rhinos.

    Global Recognition

    1. Kunming-Montreal Global Biodiversity Framework (2022): Encourages conservation through Protected Areas + Other Effective Area-Based Conservation Measures (OECMs).
    2. IUCN: Promotes connectivity conservation and integrated landscape management.
