Overview
A recent modelling study published in Environmental Research: Climate projects that India’s forest cover could store almost twice the amount of carbon it does today by the end of the century if the present trajectory of greenhouse gas emissions continues. The study, involving scientists from several Indian institutes, offers a granular forecast of how forest carbon stocks will evolve under climate change.
Key Developments
- The model predicts a potential increase of up to 90% in carbon sequestration capacity of Indian forests by 2100.
- These projections differ markedly from the official numbers compiled by the Forest Survey of India (FSI), which currently estimate a lower growth rate.
- The study underscores that the magnitude of carbon storage is highly sensitive to future emission pathways, highlighting the importance of India’s climate commitments.
Important Facts
• The research uses climate‑scenario simulations aligned with the IPCC’s Representative Concentration Pathways (RCPs).
• Under a high‑emission scenario, forest carbon could rise from roughly 2.5 Gt C today to about 4.8 Gt C by 2100.
• A moderate‑emission pathway still yields a substantial gain, indicating that even without drastic mitigation, forests will act as a carbon sink.
UPSC Relevance
Understanding the dynamics of forest carbon is crucial for multiple UPSC syllabi: GS3: Environment questions on climate mitigation; GS2: Polity topics on forest governance; and GS1: History for tracing the trajectory of forest management. The divergence between scientific models and official estimates also raises issues of data reliability and policy formulation.
Way Forward
• Strengthen coordination between research institutions and the FSI to integrate modelled projections into official forest inventories.
• Align national climate strategies (e.g., NDCs) with forest‑based mitigation pathways, ensuring that emission reduction targets consider the enhanced sequestration potential.
• Promote afforestation and restoration programmes that prioritize high‑carbon‑density species, thereby maximizing the carbon sink function of forests.
• Enhance monitoring mechanisms using remote sensing and ground‑based measurements to track actual carbon uptake against modelled expectations.
By bridging scientific forecasts with policy frameworks, India can leverage its forest wealth to meet climate goals while safeguarding ecological services.
