Short summary
The paper asks why the Arkavathy River in southern India is drying. The study results indicate that anthropogenic drivers like groundwater pumping, eucalyptus plantations and channel fragmentation are much more likely to have caused the decline than changing climate. The multiple-hypothesis approach presents a systematic way of quantifying the relative contributions of different drivers, contributing to the policy debate and prioritizing new scientific research.
