India's Enhanced Nationally Determined Contribution (NDC) targets net-zero emissions by 2070

November 2021

India's commitment to achieve net-zero emissions by 2070, announced at COP26, directly relates to understanding carbon cycling and energy flow in ecosystems. The target requires massive enhancement of carbon sequestration through forest restoration, afforestation, and sustainable land management. This connects to concepts of primary productivity, carbon storage in biomass and soils, and the role of ecosystems in climate regulation. The NDC emphasizes nature-based solutions, which rely on optimizing natural energy flow and nutrient cycling processes. Understanding these ecosystem processes is crucial for evaluating the feasibility and effectiveness of India's climate commitments.

UPSC Angle: Questions may test understanding of how ecosystem processes contribute to carbon sequestration, the role of forests in achieving net-zero targets, and the connection between biodiversity conservation and climate mitigation. Expect questions linking ecosystem services to climate policy.

Microplastics found in Indian agricultural soils affecting soil microbiome and nutrient cycling

March 2024

Recent research revealing widespread microplastic contamination in Indian agricultural soils has significant implications for nutrient cycling and soil ecosystem functioning. Microplastics affect soil structure, water retention, and microbial communities that are essential for nutrient cycling processes. They interfere with decomposition processes, alter soil chemistry, and can disrupt the nitrogen cycle by affecting nitrogen-fixing bacteria. This emerging environmental issue demonstrates how human activities can fundamentally alter ecosystem processes, connecting traditional ecology concepts with contemporary environmental challenges.

UPSC Angle: Emerging questions may focus on the intersection of pollution and ecosystem functioning, testing understanding of how contaminants affect natural processes. This could appear in questions about soil health, agricultural sustainability, or emerging environmental challenges.
