ASPIRE : un cadre méthodologique pour l'appréciation du succès des projets d'ingénierie et de restauration écologiques : application à une opération de restauration d'une zone humide d'altitude

Abstract

The high number of dimensions of ecological engineering and restoration projects contributes to their values but also to their assessment issues. The objective of the ASPIRE (Assessment of Ecological Engineering and Restoration Projects) framework is to provide a tool delivering a global project assessment, while also providing detailed scores for each of its dimensions. ASPIRE is composed of 3 levels: variables, objectives and the project. Variables are measured on the study site. Their values are normalized to range between 0 and 1. Objectives correspond to a variable list, and their score are the weighted mean of variables normalized values. The final project score is the weighted mean of the objectives scores. Scores attributed to variables are relative to references, therefore they can be compared to each other's, and objectives and scores can also be compared to each other's. While being calculated on the same study site measurements, variables and objectives weighting allows highlighting different visions of the project (for instance, from various stakeholders). ASPIRE is illustrated by its application on a mountain wetland restoration project.Du fait de la multiplicité des dimensions des projets de restauration, peu de retours sont réalisés pour évaluer leur réussite. Ces retours sont pourtant nécessaires à l'élaboration de projets futurs plus efficaces. Le cadre méthodologique ASPIRE a pour but de permettre une appréciation globale du projet en s'appuyant notamment sur les variables (mesures prises sur le terrain), les objectifs de la réhabilitation et le projet en lui-même
