Water has a stronger influence on vegetation variability than previously thought

Water has a stronger influence on vegetation variability than previously thought

Using state-of-the-art machine learning approaches and long-term satellite datasets of climate and vegetation, two new studies showed that at the global scale year-to-year variations in vegetation greenness are mostly regulated by water availability. This is true for 61% of the vegetated regions in the world. This is more than previously thought, because earlier studies did not consider the effects of extreme events like droughts and the long-term impacts of drivers like soil moisture. The studies were led by Ghent University.
