ZIMSEC O Level Geography Notes: Natural Resources:World Deforestation
- Deforestation is the cutting down of trees without replacing them.
- The most important role forests play in sustaining people’s lives is being threatened by the rapid disappearance of the world’s forests.
- In 2009, most of the world forests were in 10 top countries: 1) Russia, 2) Brazil, 3) Canada, 4) United States, 5) China, 6) Australia, 7) Congo, 8) Indonesia, 9) Peru and 10) India.
- World annual deforestation is estimated as 13.7 million hectares a year, equal to the area of Greece.
- The Amazon on of the world’s largest rainforest is also being destroyed.
- Some of the reasons why the world’s forests are fast disappearing, particularly in the poor communities of the developing countries are:
- Increased demand for wood fuel as population growth rates accelerate.
- Increased demand of wood-related raw materials in industries, both at home and abroad.
- Increased demand for urban expansion as more people in developing countries leave the poverty stricken rural areas for the cities.
- In developing countries urban population increased.
- Increased demand for farmland, industrial activities and large-scale agriculture as population growth increases.
