The weather in the Amazon is more often dry nowadays and when it is, the world's biggest rainforest produces vast quantities of CO2. This may be the forest's death warrant, with serious consequences for climate. Wageningen researchers see both signs of stress and a surprising degree of resilience.
A lot of water combined with heat and sunlight provide ideal conditions for luxuriant plant growth. This becomes apparent when rain suddenly becomes scarce, as it did in 2005, 2010 and 2015. The vegetation grew at a slower pace and there were more forest fires.
The forest remains a tropical rainforest
Drought causes problems for trees and other plants which are used to a humid environment. The crowns of trees thin out and some trees die off completely. The response of forests to more frequent droughts is surprising: the forest may change in the composition of species present but it remains tropical rainforest, with more or less the same amount of biomass and of sequestrated CO2.
Research chair group Meteorology and Air Quality
Ingrid van der Laan-Luijkx, a postdoc at the Meteorology and Air Quality chair group, can see such effects from Wageningen by studying the air quality above the Amazon. Van der Laan's lab is working with Brazilian researchers who take regular air samples from a small plane at different altitudes above the Amazon.
