Consider the following international agreements:
1. The International Treaty on Plant Genetic Resources for Food and Agriculture
2. The United Nations Convention to Combat Desertification
3. The World Heritage Convention
Which of the above has/have a bearing on the biodiversity?
- A. 1 and 2 only
- B. 3 only
- C. 1 and 3 only
- D. 1, 2, and 3
Explanation
Correct answer
D. 1, 2, and 3
The International Treaty on Plant Genetic Resources for Food and Agriculture focuses on ensuring the conservation and sustainable use of plant genetic resources for food and agriculture. This directly impacts biodiversity as it aims to protect the variety of plant species crucial for food security and ecosystem health. The United Nations Convention to Combat Desertification addresses land degradation in arid, semi-arid, and dry sub-humid areas. Desertification can significantly reduce biodiversity by destroying habitats and reducing plant and animal life. By working to combat desertification, this convention indirectly protects biodiversity. The World Heritage Convention focuses on preserving cultural and natural heritage sites. Conservation natural heritage sites may contribute to biodiversity conservation.
Thus 'D' is the correct answer.

Consider the following statements:
Statement I:
At the 28th United Nations Climate Change Conference (COP28), India refrained from signing the “Declaration on Climate and Health”.
Statement II:
The COP28 Declaration on Climate and Health is a binding declaration; and if signed, it becomes mandatory to decarbonize health sector.
Statement III:
If India’s health sector is decarbonized, the resilience of its health-care system may be compromised.
Which one of the following is correct in respect of the above statements?
- A. Both Statement II and Statement III are correct and both of them explain Statement I
- B. Both Statement II and Statement III are correct but only one of them explains Statement I
- C. Only one of the Statements II and III is correct and that explains Statement I
- D. Neither Statement II nor Statement III is correct
Explanation
Correct answer
C. Only one of the Statements II and III is correct and that explains Statement I
At COP28, India chose not to sign the “Declaration on Climate and Health,” and this decision can be understood by analyzing the nature of the declaration and India’s concerns. ✅ Statement I: Correct. India did not sign the COP28 Declaration on Climate and Health, unlike over 120 other countries. ❌ Statement II: Incorrect. The declaration is not legally binding; it is a voluntary political commitment. Signing it does not legally mandate countries to decarbonize their health sectors immediately. ✅Statement III: Correct. India’s concern is that rapid decarbonization of its health sector could compromise the resilience and accessibility of healthcare services, given current developmental challenges and resource constraints. Therefore, only Statement III correctly explains Statement I, while Statement II is factually wrong about the binding nature of the declaration.

Reducing Emissions from Deforestation and Forest Degradation (REDD) attempts to create financial value for the carbon stored in forests, offering incentives for developing countries to reduce emissions from forested lands and invest in low-carbon paths to sustainable development. REDD goes beyond deforestation and forest degradation, and includes the role of conservation, sustainable management of forests and enhancement of forest carbon stocks. REDD has the potential to simultaneously contribute to climate change mitigation and poverty alleviation, whilst also conserving biodiversity and sustaining vital ecosystem services. Protection of biodiversity: Forests are incredibly diverse ecosystems, and protecting them through REDD initiatives helps safeguard countless species of plants and animals. Resilience of forest ecosystems: By reducing deforestation and degradation, REDD helps maintain healthy forests that can better withstand natural disturbances like droughts, floods, and pests. Poverty reduction: Many forest communities rely on forests for their livelihoods. REDD programs can provide financial incentives for sustainable forest management, creating income opportunities and alleviating poverty. Therefore, the correct answer is 1, 2 and 3.
