Abstract

Streamflow – a key component of the water cycle – is experiencing drastic alteration due to human actions. While existing studies have widely assessed the global extent and degree of this change, understanding of its drivers has been limited because previous global-scale approaches have largely relied on modelled hypothetical scenarios. Here, we overcome these limitations by providing a systematic association analysis of streamflow change and its drivers. We use observed streamflow data in 5,163 catchments globally and combine them with data on precipitation, evapotranspiration, water use, and damming. Building on a robust annual trend...  more
