What to know about Q&A: Grasslands in more diverse landscapes can suffer less from drought

Researchers from the University of Bonn studied the impact of landscape diversity on the drought resilience of grasslands in Germany. The study suggests that more diverse agricultural landscapes, characterized by smaller farms and varied land use, are better able to store water and maintain plant biomass during extreme drought events compared to monotonous landscapes.

What happened

Q&A: Grasslands in more diverse landscapes can suffer less from drought Gaby Clark Scientific Editor Andrew Zinin Chief Editor During the heat wave of 2018, meadows and pastures also suffered from drought.

Why it matters

Are grasslands in diverse landscapes more resilient to yield losses than those in monotonous regions?

Common ground

Researchers at the University of Bonn, led by Marco Ferro and Dr.
