| Abstract: | Soil management practices are of particular importance, as they are the basis of 60% of planetary ecosystem services. Positive environmental externalities are associated with methods inspired by agroecology, whereas conventional methods generally have elevated indirect environmental costs. Public policies that take this reality into account are needed to make agriculture a solution rather than an obstacle to the regeneration of the planetary environment. Soil-based ecosystem services, the support for primary production, climate control through carbon sequestration, hydrological services and the biodiversity associated to their delivery, are usually associated in "bundles of ecosystem services". We propose to use communities of soil macroinvertebrates, the ones visible at the naked eye, as estimators of all other services to which they are strongly correlated. Macroinvertebrates are represented by a great diversity of biological forms, and indicator species for soil functions have been identified in several studies by scientists. The 15 orders commonly found in most soils are known to soil managers. Estimating their communities is easy and inexpensive with the widely used standard ISO/TSBF method. A numerical indicator constructed from data collected in several thousand sites sampled by this method is proposed, which can be applied everywhere. It allows to calculate for any site a value that has been shown to be a reliable proxy for the global chemical, physical and biological functions that these invertebrates stimulate in the soil, in mutualistic associations with other soil organisms. In conclusion, we discuss the feasibility of a generalized use of this indicator by farmer communities as a support for public policies that will organize the fair recognition and remuneration of positive externalities generated by some practices. |

Des externalités environnementales positives sont associées aux méthodes inspirées de l’agroécologie alors que les méthodes conventionnelles ont généralement des coûts environnementaux élevés. Des politiques publiques qui prennent en compte cette réalité sont nécessaires pour faire de l’agriculture une solution plutôt quun obstacle à la régénération de l’environnement planétaire. Les services écosystémiques liés aux sols, le soutien à la production primaire, la régulation du climat, les services hydrologiques et la biodiversité associée à leur fourniture forment des ensembles liés de services écosystémiques. Nous proposons d’utiliser les peuplements de macroinvertébrés du sol, ceux visibles à l’œil nu, comme estimateurs de tous les autres services auxquels ils sont fortement corrélés. De nombreux arguments soutiennent cette proposition : ils sont représentés par une grande diversité de formes biologiques et les 15 ordres que l’on trouve couramment sont connus des gestionnaires de sols ; l’estimation de leurs communautés par la méthode ISO/TSBF est facile et peu coûteuse. Finalement, l’indicateur numérique construit à partir de données collectées dans plusieurs milliers de sites échantillonnés par cette méthode peut être appliqué partout, permettant de calculer pour n’importe quel site un indicateur des fonctions chimiques, physiques et biologiques globales que ces invertébrés stimulent, en association avec les autres organismes du sol. Nous discutons en conclusion de la faisabilité d’une utilisation généralisée de cet indicateur par les communautés paysannes comme support aux politiques publiques qui organiseront leur juste reconnaissance et rémunération. |
