9.4 Managing Forests – Cheat Sheet
Why Sustainable Forest Management is Needed
| Reason | Explanation | Example |
|---|---|---|
| Carbon Sink & Store | Young forests absorb CO₂ (sink); mature forests hold carbon (store) → regulate climate | Amazon rainforest stores billions of tonnes of carbon |
| Role in Water Cycle | Forests intercept rainfall, promote infiltration, maintain groundwater & reduce flooding | Himalayan forests regulate river Ganges flow |
| Prevention of Soil Erosion | Roots bind soil, reduce runoff & landslides | Deforestation in Nepal increases erosion |
| Biodiversity & Genetic Resource | Forests provide habitats and genetic material for future crops & medicines | Tropical forests house 50% of world’s species |
| Food & Medicine | Forest plants provide fruits, nuts, herbs, pharmaceuticals | Quinine (anti-malarial) from cinchona tree |
| Industrial Raw Materials | Timber, paper, latex, oils, resins | Teak, mahogany logging |
| Ecotourism | Generates income & promotes conservation | Costa Rica’s rainforest tourism |
Quick Pointers
- Forests = climate regulators, biodiversity hubs, resource providers.
- Unsustainable use → loss of carbon storage, soil fertility, and species.
- Sustainable management = balance: conservation + controlled use + economic benefits.
