When the World Biodiversity Day is observed?

The correct answer is B) 22 May. World Biodiversity Day, formally the International Day for Biological Diversity, marks the adoption of the text of the Convention on Biological Diversity (CBD) on 22 May 1992 in Nairobi. The UN General Assembly later fixed 22 May as the annual observance.

• A) 22 March is World Water Day, not biodiversity. This is the date most aspirants confuse, because the day and month look similar to 22 May.
• C) 23 June is not a biodiversity observance. Do not link it to environment days either.
• D) 16 April does not correspond to any biodiversity observance.

The core concept is the CBD, which came out of the Rio Earth Summit and has three objectives: conservation, sustainable use, and fair sharing of genetic resources. The Nagoya Protocol on access and benefit sharing and the 2022 Kunming-Montreal Global Biodiversity Framework extend this. For Mains GS-3, this links to biodiversity loss, conservation policy, and the Biological Diversity Act, 2002 in India.

Trap: Mixing up observance dates. Remember 5 June is World Environment Day and 22 March is World Water Day, so 22 May is the one to pin to biodiversity.
