Reimagining Urban River Bathing in Europe: A Multisectoral and Interdisciplinary Dive Into Lyon's Rivers (France)
No full textInternational audienceUrban river bathing is re‐emerging across Europe, driven by social demand and climate change impacts. The Urban Bathing Consortium, an interdisciplinary and intersectoral consortium initiated at the University of Lyon (France), is at the forefront of studying the challenges and opportunities of creating and managing healthy, safe, and accessible river bathing spaces. Through interdisciplinary collaboration among researchers and stakeholders, the consortium proposed an analytical framework, identifying seven critical dimensions for urban river bathing: the history and revival of city‐river relationships, legal and regulatory frameworks, bathing water quality, river drowning risks, river ecosystems, social perspectives, and urban planning. By examining these dimensions with state‐of‐the‐art approaches and drawing on Lyon's experiences, the study provides scientific insights and practical recommendations for future sustainable urban river bathing development. These include revitalizing historical city‐river connections, aligning local regulations with EU guidance, advancing holistic microbial water quality control, enhancing safety measures, incorporating ecological considerations, balancing competing river uses in urban planning, and addressing social needs for inclusive river governance
Défaut d'acceptabilité sociale
No full textLe « défaut d’acceptabilité sociale » est souvent évoqué pour expliquer les difficultés rencontrées lors de la mise en œuvre de projets. Cette explication, commode, masque – parfois intentionnellement – les multiples facteurs qui expliquent que de tels projets ne se réalisent pas. A travers le cas de projets énergétiques mobilisant le sous-sol français abandonnés suite à des contestations dans différentes filières, cet article montre que plus que les conflits sociaux, ce sont les défauts de portage, industriel et politique, de ces projets qui expliquent les échecs des projets – appelant donc à relativiser le « défaut d’acceptabilité sociale »

Combined effects of soil multi‐contamination by metals and metalloids and drought slow down the ecological restoration of a Mediterranean scrubland
No full textInternational audienceIn Mediterranean ecosystems, soil contamination by metals and metalloids and drought represent major abiotic stresses whose combined effects on plant communities remain poorly understood, hindering effective ecological restoration practices. Here we evaluated the responses of plant community and species to combined stresses during a 4-year ecological restoration operation in Mediterranean scrubland. We conducted monthly monitoring of plant communities across 20 restoration plots, analyzing taxonomic and phylogenetic diversity attributes alongside soil contamination levels and drought indices using mixed-effects and hurdle models. Our results highlight that both stresses combined reduced taxonomic diversity and the diversity of distant lineages within the plant community by exerting a strong environmental filtering on species. Synergistic effects revealed that species richness decreased more strongly under high drought at low contamination levels than at high contamination levels, suggesting prior selection for tolerant species. Annual species were primarily impacted by drought through stress-avoidance strategies, while perennial species were more affected by metal and metalloid contamination despite their stress-tolerance mechanisms. Our findings highlight the importance of considering combined stress effects in restoration planning and identify phylogenetic diversity as a powerful criterion for species selection. Several perennial species, particularly Coronilla juncea, showed high tolerance and restoration potential for metal and metalloid-contaminated Mediterranean ecosystems facing increasing drought under climate change

The Climate Archives of Indochina Insights for Understanding Climate Change in Vietnam and Southeast Asia
No full textThis article presents a new historical climate database called Climate data rescue of Vietnam, Cambodia, and Laos. It covers the period from 1867 to 1973. The oldest data were produced by military hospitals according to methods prescribed by the Ministry of the Navy since 1851, then from 1898 onwards by the Indochina Meteorological Service, which developed a vast network of meteorological and rainfall stations throughout the Indochinese peninsula. The data are very abundant (temperature, atmospheric pressure, precipitation, insolation, etc.). The article presents both their diversity and the diversity of their media, as well as the history of their journey between Vietnam and France since the 1950s. It describes the various research steps that led to the recovery of the data and their centralization in a single data depository to make them available to the scientific community
Géographie des activités de recherche et hiérarchies urbaines
No full textUne version en anglais du chapitre et de l'ouvrage a été publiée en 2025 chez WileyInternational audienceCe chapitre discute l’écart observé entre la hiérarchie des villes sous l’angle de leurs activités de recherche et la hiérarchie urbaine traduite par la distribution de la population. En prenant le cas des systèmes français et britanniques, il montre que la géographie de la production scientifique est fonction de la répartition des effectifs académiques et qu’à effectif donné, les villes les plus peuplées ne sont pas plus scientifiquement productives que les autres. Quelques spécificités disciplinaires sont identifiées : la médecine apparaissant concentrée dans les plus grandes villes contrairement aux sciences humaines et sociales dont le degré de concentration varie selon les systèmes nationaux de recherche
Le circulus au XXe siècle : résurgences et métamorphoses de l’idéal du recyclage agricole des excreta à l’heure de la Grande accélération (France, années 1930 – années 1980)
No full textInternational audienceFrom its initial formulation as ‘circulus’ in the mid-19th century to the urine and faecal matter recycling projects that emerged at the beginning of the 21st century to address the crossing of planetary boundaries and its local consequences, the concept of agricultural recycling of excreta has spanned the 20th century. While the 20th century saw an exacerbation of the urban-rural rift, and the gradual end of traditional recycling practices in particular, criticism of these trends and their socio-environmental effects continued to rise in step with the crises generated by industrial growth. Although it lost its name, the Circulus utopia was reformulated many times in the century of the Great Acceleration. We find echoes of it among the promoters of biodynamic agriculture in the 1930s and 1940s, among certain socialist planners in the post-World War II era and in the ecologist and anarchist movements of the 1970s. By tracing the evolution of this ideal, this article sketches its history and attempts to bridge the gap between past and present excreta recycling utopias.Entre sa formulation première sous le nom de circulus au milieu du XIXe siècle et les projets de recyclage des urines et des matières fécales qui émergent au début du XXI e siècle pour lutter, entre autres, contre le franchissement des limites planétaires et ses effets locaux, l’idéal du recyclage agricole des excreta a traversé le XXe siècle. Si ce dernier est celui de l’exacerbation de la rupture entre villes et campagnes, et notamment de la fin progressive des pratiques anciennes de recyclage, les critiques contre ces tendances et leurs effets socio-environnementaux n’ont cessé de renaître au diapason des crises générées par la croissance industrielle. Si elle a perdu son nom, l’utopie du circulus a ainsi connu de nombreuses reformulations au siècle de la Grande accélération : on la retrouve chez les promoteurs de l’agriculture biodynamique dans les années 1930 et 1940, chez certains planistes d’obédience socialistes de l’après-Seconde Guerre mondiale et dans les mouvements écologistes et libertaires des années 1970. En en suivant la trajectoire, les échos et les évolutions, cet article dresse une esquisse de généalogie, et tente de faire le pont entre les utopies passées du recyclage des excreta et les projets présents

Precariousness in High-Growth Economies: Comparing Labor in Contemporary China and in Postwar Japan and France
No full textInternational audienceThis book is the culmination of advanced historical and sociological fieldwork in China, Japan, and France. It explores the evolution of working and living conditions in industrialized societies that have reached a certain level of wealth in a few decades, seeking to offer a more nuanced view on the profound changes experienced by the population in their daily lives. While high growth is generally associated with an increase in workers' standard of living, the high growth seen in China over the last 30 years has also produced situations of precariousness among the working class. This book questions the link between rapid growth and the generalized securitization of the salaried population, which has been assumed in contemporary sociological works, focusing not only on the evolution of labor and life conditions but also on how labor-relation actors and experts perceive the precariousness experienced in the context of high growth
