This document discusses the use of data and assessment tools in soil erosion control. It describes how the Global Soil Erosion model (GloSEM) uses data on past erosion to create maps showing areas of accelerated soil loss. It also discusses the Global Soil Organic Carbon Map (GSOCmap) which was developed using top-down and bottom-up approaches to knowledge and data on soil organic carbon. The document promotes taking a multilevel approach that integrates different processes like water, wind, and tillage erosion into models to create comprehensive soil assessment maps.
