• Forests are often cleared for farming activities.
• The cleared land provides suitable habitats for mosquitoes to
breed. This is because water is less able to seep into bare
ground with the removal of vegetation due to forest clearance.
This causes water to accumulate on the surface of the ground
to form pools of stagnant water, allowing mosquitoes to
• The destruction of naturally
vegetated areas causes biodiversity
loss. This includes predators of
mosquitoes, such as fish, birds,
dragonflies and bats. The loss of
these predators allows mosquito
populations to increase.
• Agriculture has also contributed to
the rise in mosquito populations.
Mosquitoes have more places to
breed due to the increase in
irrigation-based intensive agriculture
such as wet rice farming. The flooded
rice fields provide a conducive
environment for mosquitoes to breed.
• The water in deforested areas also tends to be more pH
neutral, unlike water found on the forest floor. Water with
neutral pH is suitable for mosquito larvae to survive. In Africa,
Asia and Latin America, forest clearance has increased the
incidence of malaria.
