A recent study reveals that climate change and increased greenhouse gas emissions are likely to cause significant forest losses in Himalayan Cedar, known as deodar. The study conducted by Indian researchers examined 17 sites across different climates in the Himalayas. While deodar is prized for its timber, medicinal uses, and cultural significance, the study projects up to a 38% decline in growth due to climate crisis in low- and mid-latitude regions. The analysis predicts a moderate growth increase for deodar in high-latitude sites. Factors including precipitation changes and insect attacks contribute to this threat.
Facts/Terms for UPSC Prelims
- Himalayan Cedar (Deodar): Also called Cedrus deodara, it’s a coniferous tree species known for its timber quality, medicinal properties, and cultural importance in the Hindu Kush Himalayas.
- Greenhouse Gas Emissions: Refers to the release of gases like carbon dioxide into the atmosphere, trapping heat and causing global warming.
- Climate Scenarios (RCP 4.5 and 8.5): RCP 4.5 represents a moderate emissions scenario, while RCP 8.5 represents a high emissions scenario, both impacting future climate predictions.
- Anthropogenic Activities: Human-caused actions, such as deforestation, that contributes to environmental changes.
- Tree Ring Studies: Analyzing the growth rings in trees to understand past climate conditions and growth patterns over time.
