SERENA EJPSOIL IT TUS SOC Loss SOC

The internal EJP SOIL project SERENA contributed to the evaluation of soil multifunctionality aiming at providing assessment tools for land planning and soil policies at different scales. By co-working with relevant stakeholders, the project provided co-developed indicators and associated cookbooks to assess and map them, to report both on soil degradation, soil-based ecosystem services and their bundles, under actual conditions and for climate and land-use changes, at the regional, national, and European scales.

The map is the result of applying the SOC loss cookbook developed in SERENA/EJP-Soil. It is based on Tuscany Region SOCdatabase (Gardin et al., 2021). Not freely available (Lamma Consortium). More information and requests to: info@lamma.toscana.it.

Three versions of the map were produced.

In versions v1 and v2, the dataset corresponds to a map of SOC concentrations for the Tuscany Region produced using a geostatistical approach. Ordinary kriging (Chilès & Delfiner, 2012) coupled with local geostatistics (LGS) was used to map SOC concentration (%) in the topsoil (0-30 cm) at a regional scale in the Tuscany Region (Italy). The map has a 50 m spatial resolution.

In version v3, a different approach to applying SOC loss cookbook was used. Particularly, Random Forest regression algorithm with numerous spatial covariates was applied for mapping SOC content (%) in the topsoil (0-30 cm) at regional scale in Tuscany Region (Italy).  The map has a 100 m spatial resolution.
