Environment & Ecology Current Affairs Previous Year Questions (PYQs)

Detailed Explanation:

Correct Answer: ✅ Option 1 — The European Union

The European Union enacted the Nature Restoration Law (NRL) to restore degraded ecosystems, enhance biodiversity, and strengthen climate resilience. It is one of the world's most ambitious legally binding nature restoration frameworks.

✅ Option A is Correct: The European Union adopted the Nature Restoration Law (2024) with legally binding restoration targets for ecosystems across member states.

❌ Option B is Incorrect: The World Bank provides financing and technical assistance but does not enact such laws.

❌ Option C is Incorrect: The Organisation for Economic Co-operation and Development offers policy recommendations but does not pass binding environmental legislation.

❌ Option D is Incorrect: The Food and Agriculture Organization supports food security and agriculture but does not enact regional laws like the NRL.

Short Notes: Nature Restoration Law (NRL)

• The Nature Restoration Law was adopted by the European Union in 2024.

• It aims to restore degraded terrestrial, freshwater, coastal, and marine ecosystems.

• The law supports the EU's Biodiversity Strategy 2030.

• It contains legally binding restoration targets for member states.

• Restoration of wetlands, forests, grasslands, rivers, and pollinator habitats is a key focus.

• Healthy ecosystems help in carbon sequestration and climate adaptation.

• The NRL is considered a major step in tackling biodiversity loss and climate change simultaneously.

Correct Answer: ✅ Option 1 — The Asian Development Bank (ADB)

The Asian Development Bank launched the Nature Solutions Finance Hub for Asia and the Pacific to mobilize investments for nature-based solutions (NbS). The initiative aims to address climate change, biodiversity loss, and ecosystem degradation by supporting projects that use natural systems for environmental resilience.

✅ Option 1 is Correct: ADB launched the Nature Solutions Finance Hub for Asia and the Pacific.

❌ Option 2 is Incorrect: The Asian Infrastructure Investment Bank did not launch this initiative.

❌ Option 3 is Incorrect: The New Development Bank is not associated with this hub.

❌ Option 4 is Incorrect: The International Bank for Reconstruction and Development did not launch the Nature Solutions Finance Hub.

Short Notes: Nature-Based Solutions (NbS)

• Nature-based Solutions use natural ecosystems to address environmental challenges.

• Examples include mangrove restoration, afforestation, wetland conservation, and watershed management.

• NbS help in climate mitigation, climate adaptation, and biodiversity conservation.

• The ADB Nature Solutions Finance Hub focuses on Asia-Pacific countries.

• It aims to mobilize public and private finance for environmental projects.

• Healthy ecosystems provide services such as carbon sequestration, flood control, and water purification.

• NbS are increasingly recognized as cost-effective climate solutions.

Detailed Explanation:

Answer: Option 1 — Database created by coalition of research organisations

The Climate Action Tracker (CAT) is an independent scientific analysis created and maintained by a coalition of research organisations, specifically Climate Analytics and NewClimate Institute. It is not a UN body, IPCC wing, or UNFCCC committee, but rather an independent initiative that tracks government climate action and measures it against the Paris Agreement goals of limiting global warming to well below 2°C and pursuing efforts to limit it to 1.5°C. The CAT has been providing independent analysis to policymakers since 2009, quantifying and evaluating climate change mitigation targets, policies, and actions across countries.

📝 Short Notes: Climate Action Tracker

• Nature: Independent scientific analysis platform tracking government climate commitments and actions
• Established: 2009, providing analysis for over a decade
• Managed by: Coalition of two research organisations - Climate Analytics and NewClimate Institute
• Primary Function: Tracks national emission reduction pledges and measures them against Paris Agreement targets (well below 2°C, pursuing 1.5°C)
• Methodology: Uses MAGICC climate model to quantify likely temperature increases based on country actions
• Scope: Evaluates mitigation targets, policies, and actions; aggregates country-level data to global projections; develops sectoral analysis for climate pathways
• Independence: Not affiliated with UN, IPCC, UNFCCC, UNEP, or World Bank - operates as autonomous research initiative
