Consider the following programmes: 1. Afforestation and development of wastelands. 2. Reforestation and replantation in existing forests. 3. Encouraging the wood substitutes and supplying other types of fuel. 4. Promotion of wide use of insecticides and pesticides to restrict the loss of forest area from degradation caused by pests and insects. Select the correct answer by using the codes given below: Codes:

1. The question asks to identify programmes related to forest conservation and development. 2. Statement 1: Afforestation (planting trees on non-forest land) and development of wastelands contribute positively to increasing green cover. This is a valid programme. 3. Statement 2: Reforestation (replanting in depleted forests) and replantation in existing forests aim to restore forest health and density. This is a valid programme. 4. Statement 3: Encouraging wood substitutes and supplying other types of fuel reduces pressure on forests for timber and firewood. This is a valid conservation strategy. 5. Statement 4: Promotion of wide use of insecticides and pesticides is generally harmful to forest ecosystems and biodiversity, and not considered a sustainable forest management practice, despite the stated aim of restricting loss from pests. This is not a correct approach. 6. Therefore, programmes 1, 2, and 3 are appropriate measures.
