Threats to rainforest ecosystemsAs we have seen previously, rainforests are subjected to a range of natural disturbances, mainly due to cyclones and storm damage, but also drought, fire and volcanic eruptions are other natural processes that effect rainforest ecology. Human activities are increasingly having a major impact on tropical rainforest via deforestation and degradation (Figure 7, Figure 8). There are about 109 ha of tropical forests in the world and about 1% per annum is converted and degraded each year to other land uses, namely;

  • slash-and-burn farming
  • logging operations
  • commercial farming
  • cattle grazing
  • firewood collection
  • mining
  • infrastructure development, especially roads
