PUR LAB METHODOLOGY

UNE APPROCHE HOLISTIQUE

METHODO1

CLASSIFICATION DES SERVICES SOCIO-ENVIRONNEMENTAUX

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.METHODO2

PROTOCOLES DE MESURE TERRAIN

Number4 DÉFINITION DES PROTOCOLES DE MESURE

En fonction du service: protocole générique applicable sur tous les projets, ou protocole spécifique adapté au contexte:

  • Développement de méthodes expérimentales
  • Stratification de la zone afin de réaliser des mesures sur des profils différents

Number5 Application DES PROTOCOLES TESTÉS

  • Mise en oeuvre du protocole
  • Application du protocole dans le temps: collecte régulière des données sur le service mesuré

SERVICES QUANTIFICATION AND VALUATION

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:

  • Specific: accurately refer to a single service.
  • Measurable: specify thresholds that are measurable at a reasonable cost.
  • Achievable: should not require excessive technical, financial or resource inputs.
  • Relevant: focussed on achieving management objectives.
  • Tangible: defined clearly and free from subjective elements.

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.
