How many agreements are there in Agenda-21 ?

Agenda 21 is the non-binding action plan adopted at the UN Conference on Environment and Development (Earth Summit), Rio de Janeiro, 1992. The question's wording is loose: the document is organised into four sections, which is what the examiner means by 'agreements', and those four sections contain 40 chapters.

The four sections are: I. Social and economic dimensions; II. Conservation and management of resources for development; III. Strengthening the role of major groups; IV. Means of implementation.

• Option A (4): correct, matching the four sections.
• Option B (5), C (6), D (7): none of these matches the structure of Agenda 21. Chapters run to 40, not 5 to 7, and the sections number four.

Core concept: Agenda 21 is the blueprint for sustainable development, and it fed into local-level Agenda 21 plans and later the 2030 Agenda and SDGs. For Mains, it is a good anchor for questions on the environment-development balance and the North-South debate over financing.

Trap: candidates mix up sections with chapters (40) or with the Rio Declaration's 27 principles, or with the three conventions (UNFCCC, CBD, UNCCD) that came out of Rio.
