The Amazon forest, one of the world's largest biodiversity and carbon repositories, is highly vulnerable to drought . The Amazon forest was highly impacted by the unprecedented droughts and higher temperatures observed in 1998, 2005, 2010 and 2015/2016, which are attributed partly to climate change. This resulted in high tree mortality rates and basin-wide reductions in forest productivity, momentarily turning pristine forest areas from a carbon sink into a net source of carbon to the atmosphere . Other terrestrial ecosystems in CSA have been impacted by climate change, through persistent drought or extreme climatic events. The combined effect of anthropogenic land use change and climate change increases the vulnerabilities of terrestrial ecosystems to extreme climate events and fires .
