|'Following this study, we can start to answer big questions like, 'how does climate drive erosion?'' says Bierman. In other words, a clearer picture of what global erosion has looked like in the recent past will start to illuminate what is likely to happen in the future as human impacts and land-use decisions play out.
'We want a predictive model,' says Bierman, 'we want to be able to have somebody say, 'here's my drainage basin, here's the climate, here's the rock type, here's the slope, here's the mean annual precipitation: how quickly is this eroding?' That's what you need for land management.'
