About the IUCN World Heritage Outlook
• The World Heritage Outlook is a global assessment published every 3–4 years by the IUCN to evaluate the conservation status of natural World Heritage sites.
• It assesses 63 natural sites across Asia under four categories — Good, Good with Some Concerns, Significant Concern, and Critical.
• The 2025 report noted that the share of sites with “significant concern” has risen from 26% (2020) to 30% (2025), highlighting worsening pressures from climate change, tourism, and invasive species.
Indian Sites under Significant Concern:
Site Name | Location | Key Issues |
Western Ghats | Spanning Maharashtra, Goa, Karnataka, Kerala, Tamil Nadu | Loss of evergreen forest (−5%), urbanisation, tourism, infrastructure projects |
Manas National Park | Assam (India–Bhutan transboundary park) | Habitat degradation, poaching, flood damage, invasive species |
Sundarbans National Park | West Bengal (India–Bangladesh transboundary park) | Climate change, sea-level rise, erosion, and tourism pressure |
Key Observations from IUCN Outlook 2025:
• India’s status: Out of 7 Indian natural World Heritage sites, 1 site (Khangchendzonga NP, Sikkim) is rated “Good”, 4 sites (Kaziranga, Nanda Devi, Valley of Flowers, Keoladeo, Great Himalayan NP) are “Good with Some Concerns”, 3 sites (Western Ghats, Manas, Sundarbans) are under “Significant Concern.”
• 1 site (Khangchendzonga NP, Sikkim) is rated “Good”,
• 4 sites (Kaziranga, Nanda Devi, Valley of Flowers, Keoladeo, Great Himalayan NP) are “Good with Some Concerns”,
• 3 sites (Western Ghats, Manas, Sundarbans) are under “Significant Concern.”
• Top threats: Climate change replaced hunting as the most widespread threat to Asian sites, followed by tourism and invasive alien species.
• Infrastructure risk: Roads and railways have newly entered the top five threats, causing habitat fragmentation and wildlife mortality.
