IUCN World Heritage Outlook 4 report flags threats to Western Ghats and South Asian sites

The IUCN World Heritage Outlook 4 report has categorized the Western Ghats, Manas National Park, and Sundarbans as sites of 'significant concern.' The report identifies four primary threats to these regions: climate change, unsustainable tourism, invasive alien species, and infrastructure development like roads and dams. While natural World Heritage sites cover less than 1% of the Earth's surface, they harbor 20% of mapped species richness. The report calls for urgent management interventions and highlights the role of the Kunming-Montreal Global Biodiversity Framework in addressing these conservation challenges.

Key Points

  • The Western Ghats are threatened by habitat fragmentation due to hydropower projects and road construction.
  • Climate change is forcing species in the Western Ghats to redistribute to higher altitudes.
  • Invasive species like eucalyptus and acacia are colonizing natural forests in the Nilgiris.
  • The report notes a decrease in the percentage of Asian sites with a 'positive conservation outlook' since 2014.
