🦗 Insect-Based Feed: A Sustainable Tool Against AMR 📍 Why insect feed matters for India & the world: ✅ Helps cut antimicrobial resistance (AMR) by reducing overuse of antibiotics in livestock. ✅ Uses fewer resources — water, land, and energy — than fish or soy-based feed. ✅ Offers better digestibility and protein content, leading to healthier livestock. ✅ Reduces greenhouse gas emissions & waste; can grow on food industry scraps. ✅ Research by ICAR, CIBA, and private firms (e.g., Bharati Recyclers, Agrigrow) confirms feasibility in India. ✅ Globally, insect feed (e.g., black soldier fly, mealworms) is approved in EU, USA, etc. 📉 Cost-effective & eco-friendly: One kg of protein from black soldier fly larvae = much lower cost & pollution than fish/soy protein.

📝 Mains Question (GS3 – Environment & S&T) Q. Discuss the role of alternative livestock feed in addressing antimicrobial resistance and ensuring sustainable agriculture in India.

🔆 India Leads on Climate Finance at Bonn Talks 📍 Key Highlights from Bonn Climate Negotiations: ✅ India led developing nations in reopening talks on Article 9.1 of the Paris Agreement — focusing on “provision” of climate finance, not just mobilization. ✅ The USD 300 billion/year from 2035 pledge by developed nations is far below the required USD 1.3 trillion/year for developing countries. ✅ India rejected the Baku COP29 consensus as “abysmally poor”, arguing it bypassed the binding obligations under Article 9.1. ✅ Article 9.1 and 9.3 are independent — the former requires direct finance; the latter only mobilization. ✅ The issue paused talks for 2 days; India gained strong support from other developing countries. ✅ A formal report will be tabled before COP30 (Belem, Brazil, end of 2025).

📌 Prelims Question: Which of the following statements about climate finance under the Paris Agreement is/are correct? 1. Article 9.1 requires developed countries to provide financial resources directly to developing nations. 2. Article 9.3 is legally binding and mandates developed countries to raise USD 300 billion per year. 3. Both articles are part of the UN Framework Convention on Climate Change. Select the correct answer: (a) 1 only (b) 1 and 2 only (c) 1 and 3 only (d) 1, 2 and 3 Answer: (a)

📝 Mains Question (GS3 – Environment): How has India shaped the global discourse on climate finance in recent years? Discuss with reference to the Bonn 2025 negotiations.
