Current state of the forest industry
Forests cover about one third of the world's land. The forest industry is everything that grows, cuts, moves, processes and sells wood. It gives jobs to millions of people, many in villages.
Every year the world cuts about 4 billion m³ of wood. Roughly half is burned as fuel, mostly in poorer countries. The rest is industrial wood: logs for sawmills, panel factories and paper mills.
The chain has four links: forest → sawmill → factory → shop. At each link people add work, so the price of the product rises. This is called adding value. Today the industry is changing: more recycling, more care for forests, and more use of chips and waste.
Structure of timber demand
Demand means how much of a thing people want to buy. Timber demand has four main parts:
- Sawn timber for houses, doors and furniture.
- Wood panels such as plywood and particle board.
- Pulp and paper for books, packing and tissue.
- Fuel such as firewood, charcoal and pellets.
Demand changes when population grows, when people build more houses, when the price changes or when a new material (steel, plastic) can replace wood. A rising demand with fixed supply makes prices go up.
Where does the wood come from? Home supply and imports
Supply is how much wood is available. A country gets wood from its own forests (domestic supply) and from imports (wood bought from other countries). The share of need met by home forests is the self-sufficiency rate.
Some countries have large forests but few people, so they can sell wood. Others have many people and less forest, or they have forests but protect them, so they buy wood. Using only imports can make prices unstable; using only home wood needs well-managed forests.
Forest industries abroad
In big forest regions such as northern Europe, North America and parts of the tropics, large sawmills and pulp mills export wood and paper. Countries with huge populations buy lots of logs, pulp and boards. Ships carry most of the wood, so ports are important.
Trade rules matter too. Some wood must be shown to come from legal and well-managed forests (certified wood). Buyers who ask for this push the whole industry to protect forests. India, for example, has forest on roughly one fifth to one quarter of its land and buys a large part of its timber from abroad.
Try it: trace one product
Pick one wooden thing at home: a pencil, a door or a notebook. Write the chain: forest → mill → factory → shop → you. Guess where the wood came from: home or abroad? Then, in the 3D, move the import slider and say what would happen to a local sawmill if imports rise.
Key formulas and definitions
- Chain: forest → sawmill → factory → shop (value added at each step)
- Self-sufficiency rate (%) = home wood ÷ total wood used × 100
- Total supply = home supply + imports
- Demand parts: sawn timber, panels, pulp and paper, fuel
- Price rises when demand grows faster than supply
Worked examples
1. A country uses 100 million m³ of wood. 40 million m³ comes from home forests. Find the self-sufficiency rate and the imports.
Self-sufficiency = 40 ÷ 100 × 100 = 40%. Imports = 100 − 40 = 60 million m³.
2. Demand is: sawn timber 35%, panels 15%, paper 30%, fuel 20%. For 200 million m³ in total, how much goes to paper?
30% of 200 = 0.30 × 200 = 60 million m³.
3. A log is sold for ₹2,000. The sawmill sells the boards cut from it for ₹3,500, and the factory makes a table worth ₹9,000 from them. How much value did the sawmill and factory add?
Sawmill adds 3,500 − 2,000 = ₹1,500. Factory adds 9,000 − 3,500 = ₹5,500. Total added = ₹7,000.
4. A country's demand rises from 80 to 100 million m³ while home supply stays at 40 million m³. How many million m³ of imports are now needed, and by how much did imports rise?
Before: 80 − 40 = 40. Now: 100 − 40 = 60. Imports rose by 20 million m³.
5. Which part of demand do you think is largest in a poor village: sawn timber or fuel? Why?
Fuel. Many village homes cook with firewood because it is cheap and nearby.
Common mistakes
- Thinking all wood becomes furniture. A large part is burned as fuel and a large part becomes paper.
- Forgetting that value is added at every step, not only at the shop.
- Mixing up supply and demand. Supply is wood available; demand is wood wanted.
- Thinking imports are always bad or always good. Both home wood and imports have costs and benefits.
