The assessment and evaluation of ecosystem services is a valuable tool to support and justify sustainble soil management.
Researchers of IRNAS, CSIC have contributed to the development of a methodology to quantify changes in ecosystem services induced by soil management measures, as part of the European RECARE consortium.
A comparative analysis of the results for 26 measures applied to remediate degraded soils, in 16 case studies across Europe, has been carried out. In particular, IRNAS´s researchers have evaluated the results of amendments (biosolid compost) and tree planting (wild olive) in contaminated and remediated soils of the Guadiamar Green Corridor.
The new methodology was applied to evaluate the impacts of each 26 measures on different ecosystem services. The most relevant 15 ecosystem services were selected, grouped in provisioning, regulation and cultural services. In general, the applied soil remediation measures produced positive changes in ecosystem services. Within the regulation services, “mediation of flows” (protection from erosion) and “mediation of waste, toxics and other nuisances” (stabilization of contaminants) showed the most important positive impacts.
The methodology also detected synergies and trade-offs among ecosystem services. This holistic approach may be the base for a valuation of the benefits from each ecosystem service and the integrated management of the evaluated land.
The results have been published in the December issue of the open access journal Sustainability:
