Le PUR Lab a identifié 7 catégories de services socio-environnementaux. Pour chaque catégorie, une liste de sous-services, logiques, exhaustifs et non-redondants, a été établie: 49 au total.
En fonction du service: protocole générique applicable sur tous les projets, ou protocole spécifique adapté au contexte:
Shape and construction of the measurement device for erosion, Peru.
PUR Lab has identified 7 categories of services. For each category, PUR Lab has identified logic, exhaustive and non-redundant sub-services: 49 in total.
Soil enrichment
Erosion and landslide avoided
Better water quality
Cycle regulation
Stock increase
The methodology to quantify services is based on a review of a thousand scientific publications. Indicators to quantify the level of service are selected following the SMART criteria:
Example: “Soil fixation” indicator is the reduction in loss of arable land due to erosion, in kg/ha/year.
Valuation methods are applied to each service to get an economic value per service.
