With reference to peatlands, consider the following statements: The...
Option c is the correct answer.
- Peatland stores the carbon the plants absorbed from the atmosphere within peat soils, providing a net- cooling effect and helping to mitigate the climate crisis.
- Statement 1 is correct: Peatlands are a type of wetland. The term ‘peatland’ refers to the peat soil and the wetland habitats growing on the surface. In peatlands, year-round water-logged conditions slow plant decomposition to such an extent that dead plants accumulate to form peat.
- Statement 2 is incorrect: Peatland landscapes are varied: from temperate blanket mires with open, treeless vegetation such as the Flow Country of Scotland to swamp forests in Southeast Asia. The majority of the world’s peatlands occur in boreal and temperate parts of the Northern Hemisphere, especially, Europe, North America and Russia where they have formed under high precipitation-low temperature climatic regimes. In the humid tropics, regional environmental and topographic conditions enable peat to form under conditions of high precipitation and high temperature in Southeast Asia, mainland East Asia, the Caribbean, Central America, South America, Africa, parts of Australasia and a few Pacific Islands. Tropical peatlands may also form under mangrove forests.
- Statement 3 is correct: Peatlands are a type of wetland which is critical for preventing and mitigating the effects of climate change. Peatlands are the largest natural terrestrial carbon store. They store more carbon than all other vegetation types in the world combined.
- Knowledge Base: New areas are still being discovered. The world’s largest tropical peatland was identified beneath the forests of the Congo Basin in 2017. The new study found that the Cuvette Centrale peatlands in the central Congo Basin, which were unknown to exist five years ago, cover 145,500 square kilometres – an area larger than England.
- In many parts of the world, peatlands supply food, fibre and other local products that sustain economies. They also preserve important ecological and archaeological information such as pollen records and human artifacts. Damage to peatlands causes biodiversity loss. For example, the decline of the Bornean orangutan population by 60% within 60 years is largely attributed to the loss of peat swamp habitat.

Understanding Peatlands
Peatlands are unique ecosystems that play a significant role in the environment. Let's analyze the statements to determine which are correct.
1. Waterlogged Conditions
- Peatlands are indeed a type of wetland where waterlogged conditions prevent the complete decomposition of plant material.
- This accumulation of partially decayed organic matter leads to the formation of peat.
2. Geographic Distribution
- The statement that peatlands are restricted only to tropical areas is incorrect.
- Peatlands can be found in various regions around the world, including temperate and boreal zones. They are not limited to tropical areas.
3. Carbon Storage
- Peatlands are considered one of the largest terrestrial stores of carbon.
- They sequester carbon in the form of peat, making them critical for climate regulation and carbon cycling.
Conclusion
Based on the analysis:
- Statement 1 is correct.
- Statement 2 is incorrect.
- Statement 3 is correct.
Thus, the correct option is c) 1 and 3 only.
Peatlands are crucial for biodiversity and climate change mitigation, making their conservation vital.
