This EU addresses questions surrounding ecosystem management from a social science perspective, particularly that of "science studies." It aims to contribute to the development of a general culture related to the relationship between ecological sciences and societies, and to equip participants with the tools to analyze social issues and underlying socio-scientific controversies. The first part of the course provides the conceptual and methodological framework necessary to present a reflective tool for analyzing the roles of actors and arguments (epistemological, axiological) involved in socio-scientific controversies, and illustrates this tool with current examples. Subsequently, thematic presentations by researchers in ecology illustrate a variety of issues surrounding ecological sciences and serve as a basis for students to apply and acquire the reflective analysis tool. Students are thus assessed on their ability to use this analytical framework to take an individual and reasoned position in controversies related to ecological sciences.

The educational objective of this teaching unit is to reposition the major soil types on a global scale, explain their formation, and identify the mineral phases or main abiotic factors likely to regulate biological activity in soils. Based on this analysis, the various soil organisms (microorganisms, micro-, meso- and macrofauna) will be presented, along with their relationships, in order to reposition the cycle of organic matter and mineral elements in the soil at different temporal and spatial scales. The concepts of recycling, biogeochemical cycles and community assembly rules will also be addressed. This course unit is organized around lectures and conferences, as well as tutorials and fieldwork.
