The economics of raw milk cheese production facing the proliferation of Listeria: how to work with and “trust” the microbes? The case of the breeders and producers of Saint Nectaire.

International audiencePAPER SHORT ABSTRACT:Examining the relational rationalities of work in breeding through inter-species human-microbe collaborations to protect against the deleterious effects of Listeria, we discuss the hygienist and commercial limits of "putting microbes to work", and thus the anthropological boundaries of work.PAPER LONG ABSTRACT:In France, the systems for producing raw milk cheeses constitute an attempt to enlist microbes in the production of taste, heritage and market values. These systems, including Protected Designations of Origin, allow breeders to protect themselves from the deleterious effects of the conventional milk market which plunge a growing number of their peers into precariousness. However, they must face the threat of proliferation of pathogens in their work, including Listeria. How do they manage this microbial ambivalence in their breeding practices? This communication shows how these actors are no longer trying to fight against, but to work with microbes, via forms of inter-species collaboration, to manage the threat-proliferation of Listeria. It is based on surveys of breeders-producers from Saint-Nectaire farmers in France as part of the TANDEM research program (INRAe HOLOFLUX Metaprogram). Firstly, we show how these actors construct “microbial balances” in their breeding practices, a microbiopolitics where their “trust” in microbes plays out in the face of Listeria “attacks”, through: exogenous recruitment – powders commercial ferments – and/or endogenous – the “environment” of the farm – of microbes deemed beneficial; more or less strict controls – disinfection, etc. - of microbial populations during milking. Secondly, we will question the broader ecological disturbances, linked to the intensification of breeding practices, which induce a degradation of this microbiopolitics: the proliferation of mole rats in the meadows

How do coastal residents perceive past and future changes in a Mediterranean lagoon ecosystem services?

International audienceCoastal ecosystems provide a wide range of ecosystem services (ES) subject to strong human pressure and are included in conservation policies that aim to increase their resilience. Implementing resilience measures requires knowledge of the public perceptions of social-ecological systems so that commitment to environmental protectionmay be enhanced. Few studies address public percepion of the evolution of social-ecological systems and integrate the diversity of ES (regulating, provisioning and cultural). This article is based on a survey of 476 inhabitants and deals with their perceptions of past (50 years) and future (+15 years) ES. It focuses on the Thau lagoon (French Mediterranean) that offers many ES and where managers prioritize traditional uses such as shellfish farming and fishing. Respondents’ answers were compared with the results of scientists’ and experts’ evaluations to assess the level of public knowledge. The results indicate consistency in the qualitative and quantitative responses of local residents concerning the long-term evolution of ES and show them to have a fairly sound knowledge. However, there are some differences in trends with substantial variation for several ES probably related to judgement or anchoring biases. Furthermore, a majority of local residents had a mixed perception of local structuring ES. This innovative approach to the perceptions of ES momentum suggests that improved conservation policies must: (i) take into account the different communication and awareness requirements of people and (ii) integrate local knowledge through dialogue
