Why in the news?
- As per recent study deforestation-induced warming caused an extra 28,000 deaths per year in the tropics between 2001 and 2020.
Deforestation in the Tropics
- Deforestation: The large-scale clearing or degradation of forests, often converted into non-forest uses such as agriculture, pasture, or urban land.
- Distribution of Tropical Forests: Found mainly in Amazon (South America), Congo Basin (Africa), and Southeast Asia (Indonesia, Malaysia, etc.).
- Facts: They cover about 7% of Earth’s land area but house >50% of terrestrial biodiversity. Currently losing ~10 million hectares per year (FAO, 2020s).
- Causes:
- Agricultural Expansion
- Shifting cultivation, subsistence farming.
- Commercial crops: oil palm, soy, sugarcane, rubber.
- Cattle ranching (notably in Amazon).
- Logging
- Legal and illegal timber extraction (mahogany, teak, rosewood).
- Fuelwood and charcoal demand in Africa and South Asia.
- Infrastructure Development
- Dams, highways, urban expansion, mining activities.
- Plantations & Monocultures
- Replacement of diverse forests with monoculture plantations.
- Forest Fires
- Natural and human-induced fires (Amazon, Indonesia’s peatlands).
- Weak Governance
- Corruption, land tenure insecurity, poor enforcement of conservation laws.
- Agricultural Expansion
- Consequences of Tropical Deforestation
- Environmental Impacts
- Loss of biodiversity & extinction of endemic species.
- Increased greenhouse gas emissions → ~10–15% of global CO₂ emissions come from deforestation.
- Soil erosion, nutrient loss, desertification.
- Altered rainfall patterns, disruption of monsoons and local hydrological cycles.
- Economic & Social Impacts
- Short-term economic gains (logging, plantations) vs. long-term ecosystem collapse.
- Loss of livelihoods of indigenous and forest-dependent communities.
- Food and water insecurity.
- Global Climate Impact
- Reduces carbon sequestration capacity of tropical forests (Amazon = “lungs of the planet”).
- Intensifies global warming and climate change.
- Environmental Impacts
- Global & Regional Efforts to Curb Deforestation
- UN-REDD+ (Reducing Emissions from Deforestation and Forest Degradation) → Incentives for forest conservation.
- Convention on Biological Diversity (CBD) & Paris Agreement (2015) → Focus on forests as carbon sinks.
- Forest Stewardship Council (FSC) → Certification for sustainable timber.
- Amazon Cooperation Treaty Organization (ACTO).
- Situation in India
- India is not part of major tropical deforestation hotspots, but faces forest degradation in North-East, Central India, and Western Ghats.
- Causes: shifting cultivation (jhum), infrastructure projects, mining, monoculture plantations.
- Initiatives: Compensatory Afforestation Fund (CAMPA), National Afforestation Programme, Green India Mission, and recognition of tribal rights under Forest Rights Act (2006).
- Way Forward
- Sustainable agriculture (agroforestry, crop diversification).
- Strengthening indigenous rights and community forest management.
- Strict regulation of logging, mining, and land conversion.
- Financial incentives through REDD+, carbon markets, and payment for ecosystem services.
