See card n26: "If the soil is dried by drought it's worse because the water runs off."
2Other possible causes
Deforestation can be the direct cause of droughts because trees stock a lot of water. If they are cut down, they no longer play their part as humidity regulators.
Heatwaves can cause droughts. They often go together.
1Other possible consequence
If a lack of rain occurs while plants are growing, there is less photosynthesis and therefore a reduction in capacity of the carbon sink. In Europe, in 2018, carbon sinks declined by 18%.
