Topic: Conservation, environmental pollution and degradation
Q6. Discuss the role of peatlands in regulating the global carbon cycle. Analyse the factors responsible for greenhouse gas emissions from degraded peatlands. (10 M)
Difficulty Level: Medium
Reference: DTE
Why the question
Peatlands have gained renewed policy attention following the FAO Peat-Emit Report (2026), which updated emission factors and highlighted their importance in improving greenhouse gas inventories and climate mitigation.
Key Demand of the question
The question requires explaining the role of peatlands in regulating the global carbon cycle and analysing the major factors responsible for greenhouse gas emissions when peatlands are degraded.
Structure of the Answer:
Introduction
Briefly define peatlands and highlight their importance as major global carbon reservoirs.
Body
- Role in the global carbon cycle: Mention how peatlands regulate carbon storage and climate.
- Factors causing emissions from degraded peatlands: Explain the major processes responsible for increased greenhouse gas emissions.
Conclusion
Conclude with the need for peatland conservation, restoration and scientific monitoring to strengthen climate mitigation.
