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...

The "Grain for Green Project" is a country-wide ecological program to converse marginal cropland to forest, which has been implemented in China since 2002. To quantify influence of this significant vegetation change, Guansihe Hydrological (GSH) Model, a validated physically-based distributed hydrological model, was applied to simulate runoff responses to land use change in the Guansihe watershe...

Dirty work: We often dismiss soil as the dirt below our feet, yet it is a vital resource for food production as well as a highly complex and insuffi ciently understood ecosystem. The image shows farmers in Kyuso, Kenya terracing part of their land in order to minimise erosion losses. (Photo: ©FAO/Thomas Hug.)
