Overview
The CMS is hosting its 15th COP in Campo Grande, Brazil from 23–29 March 2026. The theme, “Connecting Nature to sustain life,” underscores the need for trans‑boundary cooperation in safeguarding migratory fauna.
Key Developments (COP15 Highlights)
- CMS now has 133 Parties, reflecting broad global commitment.
- The interim report released ahead of COP15 warns that 49 % of listed migratory species are declining and 24 % face extinction.
- India’s role: after hosting COP13 in 2020, India holds the CMS Presidency (2023‑2025) and continues to push for stricter protection of its migratory fauna.
- New scientific data on habitat loss, climate change and disease (e.g., H5N1) were highlighted as major threats.
Important Facts about CMS Appendices
- CMS maintains two appendices. A species may appear in both Appendix I and Appendix II.
- Appendix I currently contains 188 species (28 terrestrial mammals, 23 aquatic mammals, 103 birds, 8 reptiles, 26 fish). Parties must ensure strict protection, habitat restoration and mitigation of migration barriers.
- Appendix II covers species needing coordinated agreements but not necessarily the highest threat level.
- Indian species in Appendix I include Great Indian Bustard, Asian Elephant, Bengal Florican, Siberian Crane, Hawksbill, Olive‑Ridley and Leatherback Sea Turtles.
Recent IUCN Red‑List Shifts
The interim report notes that 26 species moved to a higher extinction risk category, 18 of which are migratory shorebirds. Notable upgrades:
- Swan Goose: VU → EN
- White‑winged Duck (EN → CR)
- Blue Swallow (VU → EN)
- Great Bustard (VU → EN)
- Narrow Sawfish (EN → CR)
Threats highlighted include over‑exploitation, habitat degradation, infrastructure development and the spread of H5N1 across multiple continents.
Exam Relevance
Understanding CMS is essential for GS III (Environment) and GS II (International Relations). Aspirants should be able to:
- Explain the legal nature of CMS and its linkage to the UN‑environment system.
- Distinguish between Appendix I and Appendix II criteria and the implications for national policy.
- Identify Indian migratory species under CMS protection and relate them to domestic wildlife laws (e.g., Wildlife Protection Act, 1972).
- Analyse the impact of emerging threats such as disease (H5N1) and climate‑induced habitat loss on migratory corridors.
Way Forward
To curb the alarming decline, the following steps are recommended:
- Strengthen trans‑boundary habitat corridors through joint India‑neighbor agreements.
- Integrate CMS priorities into national biodiversity action plans and the NBAP.
- Enhance surveillance for zoonotic diseases (e.g., H5N1) along migratory routes.
- Mobilise funding for community‑based conservation of key species such as the Great Indian Bustard and Olive‑Ridley turtles.
Effective implementation will require coordinated action among central and state governments, research institutions, NGOs and the international community.
