• It was later popularized internationally by the Brundtland Commission Report (*Our Common Future*, 1987) and codified at the Rio Earth Summit in 1992.
• Key Details
• The 1980 IUCN Strategy was the first international policy document to explicitly marry conservation with developmental aspirations.
• Exam Traps
• Many aspirants mistakenly select Rio Earth Summit (1992) or Brundtland Commission, unaware that the terminology originated in the 1980 World Conservation Strategy.
• Other Options
• Rio Earth Summit (Option 2) operationalized Agenda 21 in 1992.
