Consider the following pairs: International agreement/set-up - Subject 1. Alma-Ata Declaration - Healthcare of the people 2. Hague Convention - Biological and chemical weapons 3. Talanoa Dialogue - Global climate change 4. Under2 Coalition - Child rights. Which of the pairs given above is/are correctly matched?

1. Alma-Ata Declaration — Healthcare of the people: Correct. The 1978 Alma-Ata Declaration focused on primary healthcare and the goal of ‘Health for All’.

2. Hague Convention — Biological and chemical weapons: Incorrect. The Hague Conventions mainly relate to laws of war and conduct in armed conflict, not specifically to biological and chemical weapons; those are covered by separate conventions.

3. Talanoa Dialogue — Global climate change: Correct. Talanoa Dialogue was launched under the UNFCCC process to advance discussion and ambition on climate action.

4. Under2 Coalition — Child rights: Incorrect. Under2 Coalition is a climate coalition of states and regions committed to reducing greenhouse gas emissions, not child rights.

Hence, pairs 1 and 3 only are correctly matched.
