Here’s how drought stress alters soil function in the rainforest

,
Drought progressively reduces the ability of soil to consume biogenic volatile organic compounds according to a German study. The emission intensifies after soil rewetting
Due to their high carbon sequestration capacity, mangroves are estimated to be able to prevent total emissions of more than 21 billion tons of CO2 worldwide.
