Global warming is concurrently associated with a rise in occurrences of drought episodes in numerous regions worldwide, with central Chile a sad example. This region is the only Mediterranean bioregion of South America, which is considered a biodiversity hotspot due to high endemism levels and high anthropic pressure. These ecosystems since 2010 have been impacted by a period of below-average rainfall, a so-called Mega Drought (MD), so their contribution to the regional carbon sink is at risk.
