Why it happens: Most visible driver. How to avoid it: Logging is ONE of MANY drivers. Cattle (largest!), soya, palm oil, mining, infrastructure all play roles. Mention multiple. Source: 0460 Examiner Reports 2022-2024

Threats to Tropical Rainforests Part 1 Study Notes — Cambridge IGCSE Geography 0460 (2024-2026 syllabus)

Deforestation causes: cattle, soya, logging, mining, palm oil, infrastructure. Local impacts (soil, indigenous people) and global impacts (climate, biodiversity). Amazon case study.

What you’ll learn

Mapped to the Cambridge IGCSE 0460 syllabus (2024-2026).

3.6.1 — Identify causes of deforestation.
3.6.2 — Identify local and global impacts.
3.6.3 — Use a named example (Amazon).

Causes of deforestation

Multiple drivers — cattle is largest.

Cattle ranching. ~70% of Amazon deforestation. Beef exports drive demand.

Soya farming. Forest cleared for soybean cultivation; soya goes to animal feed globally.

Logging. Hardwoods (mahogany, teak) for furniture and construction. Both legal and illegal.

Mining. Gold, iron ore, bauxite. Also wildcat mining (artisanal, often illegal, mercury-contaminated).

Palm oil. Especially in Southeast Asia (Indonesia, Malaysia). Major driver of forest loss there.

Infrastructure. Roads, dams open up previously inaccessible forest to settlement.

Subsistence farming. Slash-and-burn for crops; less significant globally but cumulative.

Cambridge tip. Mention MULTIPLE drivers — not just logging.

Cattle = #1 in Amazon.
Soya, logging, mining, palm oil.
Infrastructure opens new areas.

Local and global impacts

Soil, indigenous, climate, biodiversity.

Local impacts.

Soil erosion. Trees protect topsoil; once cleared, tropical rains wash it away in months.
Indigenous displacement. Communities lose homes and cultural sites; conflicts with farmers/loggers.
Local climate change. Reduced evapotranspiration → drier microclimate.

Global impacts.

Climate change. Rainforests store ~25% of land carbon. Cutting and burning releases CO₂ — ~10% of global emissions.
Biodiversity loss. ~50% of all species in rainforests. Once lost, never recovers.
Disrupted weather patterns. Atlantic moisture pump weakened — could affect rainfall in Brazil, North America.

Cambridge tip. Balance local AND global. Mark scheme rewards both perspectives.

Local: soil, indigenous, microclimate.
Global: climate, biodiversity, weather.
Connected — habitat loss + carbon release.

Amazon case study

Largest rainforest; approaching tipping point.

Amazon — world's largest rainforest. 5.5 million km² across 9 countries (Brazil ~60%).

Scale. Lost ~20% of original forest. ~10,000 km² cleared annually.

Main driver. Cattle (~70% of cleared land).

Tipping point. Scientists warn that ~20-25% deforestation could TIP the Amazon from RAINFOREST to SAVANNA. Currently at ~20% — close to threshold. Once tipped, may not recover.

Why this matters. Amazon stores ~120 billion tonnes of CO₂. Tipping point = mass release + global biodiversity crash.

Cambridge tip. Memorise these figures.

5.5M km², 9 countries, Brazil ~60%.
~20% already deforested.
Tipping point ~25%.
Cattle = main driver.

Step-by-step worked examples — Threats to Tropical Rainforests and Sustainable Management Part 1

Step-by-step solutions to past-paper-style questions on threats to tropical rainforests and sustainable management part 1 , written exactly the way a tutor would explain them at the board.

1Causes of deforestation (8 marks)
Extended• Adapted from 0460/12 Oct/Nov 2024• deforestation
Question
Identify FOUR causes of tropical rainforest deforestation. (8 marks)
Step-by-step solution
1. Step 1
  Cattle ranching (2 marks). Largest single driver of Amazon deforestation. Forest cleared for cattle pasture; beef exports to global markets. ~70% of Brazilian Amazon clearance is for cattle.
2. Step 2
  Soya farming (2 marks). Forest cleared for soybean cultivation. Soya goes to animal feed (cattle, chicken, pigs globally). Brazil is world's #1 soya producer.
3. Step 3
  Logging (2 marks). Hardwoods (mahogany, teak) extracted for furniture, construction. Both legal and illegal. Even SELECTIVE logging damages forest structure via access roads.
4. Step 4
  Mining (2 marks). Forest cleared for mining (gold, iron ore, bauxite). In Amazon basin, also includes wildcat / artisanal mining contaminated with mercury.
Answer
Cattle ranching, soya farming, logging, mining. Other valid: palm oil, infrastructure (roads/dams), subsistence farming, urbanisation.
2Local and global impacts of deforestation (8 marks)
Extended• impacts
Question
Describe TWO local and TWO global impacts of rainforest deforestation. (8 marks)
Step-by-step solution
1. Step 1
  Local — soil erosion (2 marks). Trees protect soil from heavy tropical rain. Once cleared, topsoil washes away in months. Land becomes infertile; agriculture fails.
2. Step 2
  Local — indigenous people displacement (2 marks). Indigenous communities lose homes, livelihoods, cultural sites. Conflict with farmers/loggers. Examples: Amazonian tribes, Penan in Borneo.
3. Step 3
  Global — climate change (2 marks). Rainforests store ~25% of land carbon. Cutting and burning releases CO₂. Deforestation accounts for ~10% of global emissions.
4. Step 4
  Global — biodiversity loss (2 marks). Rainforests host ~50% of all species. Deforestation drives mass extinction. Once lost, biodiversity may never recover.
Answer
Local: soil erosion, indigenous displacement. Global: climate change (CO₂ release), biodiversity loss. Connected — habitat loss = species loss + carbon release.
3Named example — Amazon rainforest (6 marks)
Extended• case-study
Question
Using the Amazon rainforest as an example, state THREE specific facts about its deforestation. (6 marks)
Step-by-step solution
1. Step 1
  Scale (2 marks). Amazon covers ~5.5 million km² across 9 countries (mainly Brazil ~60%). Has lost ~20% of original forest. ~10,000 km² cleared annually in recent years.
2. Step 2
  Main driver — cattle (2 marks). ~70% of cleared Amazon land is now cattle pasture. Brazil is largest beef exporter globally.
3. Step 3
  Tipping point concern (2 marks). Scientists fear 20-25% deforestation could TIP the Amazon from RAINFOREST to SAVANNA. Currently at ~20% — close to threshold. Once tipped, may not recover.
Answer
Amazon: 5.5M km², 20%+ deforested, cattle is main driver, approaching tipping point.
Examiner tip
Top-band answers cite specific figures. Mark scheme strongly rewards data over generalities.

Key Definitions and Keywords — Threats to Tropical Rainforests and Sustainable Management Part 1

Definitions to memorise and the exact keywords mark schemes credit for threats to tropical rainforests and sustainable management part 1 answers — sharpened from recent examiner reports for the 2026 0460 sitting.

Deforestation
Examiner keyword
Clearance of forest for non-forest use (agriculture, mining, urbanisation, infrastructure).
Slash and burn
Examiner keyword
Cutting and burning trees to clear land. Releases CO₂ and destroys soil organic matter.
Soil erosion
Examiner keyword
Loss of topsoil by water or wind. Accelerated by deforestation; tropical soils are particularly vulnerable.
Tipping point
Examiner keyword
Threshold beyond which an ecosystem cannot recover. Amazon may approach this at ~25% deforestation.
Amazon rainforest (case study)
World's largest rainforest (~5.5 million km²). Major driver of deforestation: cattle ranching. Approaching tipping point.
