Abstract: our empirical knowledge of the world’s spatial and temporal distribution of soils comes from sparse spatial observations. This makes it challenging to predict future changes in soils based on such observations. We therefore take recourse to natural experiments such as chronosequences, where spatial variation coincides with variation in one soil forming factor, and to mechanistic modelling. Given that soils develop slowly, mechanistic modelling must happen in computer models, with the corresponding difficulties. In my colloquium, I will give examples of both approaches. I will discuss some findings from chronosequences in proglacial settings, mainly in the European Alps, and I will present my soil-landscape model LORICA, and I will argue that merging the ‘natural experiment’ and ‘computer model’ approach is the most productive way forward to more complete understanding of soil-landscape co-evolution.
