Soil maps, classification systems, and process modelling are fundamental tools for better land use planning and management. Soil mapping is important because it synthesizes complex spatial information in an understandable manner. Therefore, the production of accurate maps is a key issue because it enables farmers, consultants and government personnel to understand the variation in either soil type or individual soil properties. Soil classification systems communicate information on sustainable soil management potential and limitations. Moreover, classification systems continuously evolve in line with new scientific insights. Discussing user experiences are a key element in improving classification systems. A special focus is given to the third edition (2014) of the international soil classification system World Reference Base for Soil Resources (WRB). Furthermore, it is important to understand the causes of land and soil degradation (e.g. urban sprawl, intensive agriculture, pollution, deforestation, etc.), including the consequential environmental, social, and economic problems. In these cases, process modelling can be employed to facilitate the task of territorial planning and contribute to a sustainable landscape use. As a result, the soil can be managed accordingly and be used sustainably at the field, farm and across a given territory. This session aims to bring together studies on the use of soil classification, soil mapping and process modelling for sustainable land use management.
