Mapping for Mapping’s Sake? Ecosystems Services Maps and the Modes of (Ir)relevance of Ecological Knowledge for Nature Conservation

In the face of enduring environmental decline, ecologists are continuously exploring new ways to improve the relevance of their research and address nature conservation issues. Hoping for more relevant solutions than former species-centered conservation, some ecologists have mapped ecosystems and the services they deliver to human societies. Maps offer crucial, but understudied, relevance-making tools. By proposing a relational conceptualisation of relevance, I demonstrate that maps can make issues simultaneously relevant and irrelevant for conservation. In two mapping projects conducted at the European Union level by the Working Group Mapping and Assessment of Ecosystems and their Services and at the French regional scale by the Laboratoire d’Écologie Alpine, I investigate how the (ir)relevance of ecosystem services maps is enacted through different modes. I successively show that: ecologists employed maps to re-orient their research toward social issues, but were constrained by the available quantified data (mode A); they used maps to implement a biopolitical approach and decide which ecosystems to protect, yet grappled with the imprecision of maps (mode B); and they engaged stakeholders in map development, but had to make excessive adjustments to align with their demands (mode C). I conclude by arguing that ecosystem services maps exemplify an automation of relevance, where relevance is more conditioned by technical feasibility than by the conceptualisation of solutions to conservation issues. Ultimately, the article contributes to the relevance scholarship by advancing the concept of irrelevance, operationalising the study of modes of relevance, and demonstrating that relevance is an inherently relational process.
