Of great concern is the rate at which deforestation is occurring. Currently, 12 million hectares of forests are cleared annually - an area 1,3 times the size of KwaZulu/Natal! Almost all of this deforestation occurs in the moist forests and open woodlands of the tropics. At this rate all moist tropical forest could be lost by the year 2050, except for isolated areas in Amazonia, the Zaire basin, as well as a few protected areas within reserves and parks. Some countries such as Ivory Coast, Nigeria, Costa Rica, and Sri Lanka are likely to lose all their tropical forests by the year 2010 if no conservation steps are taken.
Deforestation in the Amazon
60-70 percent of deforestation in the Amazon results from cattle ranches while the rest mostly results from small-scale subsistence agriculture. Despite the widespread press attention, large-scale farming (i.e. soybeans) currently contributes relatively little to total deforestation in the Amazon. Most soybean cultivation takes place outside the rainforest in the neighboring cerrado grassland ecosystem and in areas that have already been cleared. Logging results in forest degradation but rarely direct deforestation. However, studies have showed a close correlation between logging and future clearing for settlement and farming.
Today deforestation in the Amazon is the result of several activities, the foremost of which include:
- Clearing for cattle pasture
- Colonization and subsequent subsistence agriculture
- Infrastructure improvements
- Commercial agriculture
- Logging
