Agricultural terraces are the most widespread archaeological landforms worldwide. Despite their far-reaching prevalence in many inhabited parts of world, soils (hereafter ‘terrace soils’) scarcely studied and nature is poorly defined. This study aims to depict a space–time framework for development calcareous stone-wall bench suggest modifications soil classification mapping. To do so, we exami...

Wetland and floodplain soils in the East African Rift of Kenya provide a record of changing palaeoclimate and palaeohydrology compatible with climate records for the mid-Holocene through the late Holocene Medieval Warm Period (~AD 800–1270) and Little Ice Age (~AD 1270–1850), documented previously in nearby lacustrine sites. Soils forming from volcaniclastic source materials in both Loboi Swamp...
