Abstract Silver played a key role in the progressive monetization of early Mediterranean civilizations. We combine Pb and Ag isotopes with volatile trace elements (Bi, Sb, and As) to assess whether, during the Roman occupation of Iberia, galena constituted a significant source of silver. We find that the Pb and Ag isotopic compositions of 47 samples of galena from eight different Iberian mining provinces, many of them exploited during Roman times, are uncorrelated. This indicates that their respective isotopic variabilities depend on different petrogenetic processes. Moreover, the range of Ag isotopic abundances is approximately six times wider than that displayed worldwide by silver coins in general and Roman silver coins in particular. Although galena from the Betics provides the best fit for Pb isotopes with Roman coins, their fit with Ag isotopic compositions is at best sporadic. We suggest that, together with Sb, Bi, and As, silver is primarily derived from fluids boiled off from differentiated mantle-derived magmas. These fluids, in turn, reacted with preexisting galena and functioned as a silver trap. Lead sulfides with ε109Ag of ~0 and unusually rich in Ag, Sb, Bi, and As were the most probable sources of ancient silver, whereas samples with ε109Ag departing significantly from ~0 reflect low-temperature isotopic fractionation processes in the upper crust.

Supplement: The supplement related to this article is available online at: https://doi.org/10.5194/nhess-21-3749-2021-supplement. Copyright © 2021 The Author(s). In order to mitigate the potentially dramatic effects of natural hazards, risk management measures are critical. However, the lack of interdisciplinary indicators and adaptable governance frameworks highlights society's vulnerability in the particular context of global environmental and climate change. This interdisciplinary research aimed at identifying reliable risk indicators and societal responses regarding natural hazards and climate change impacts to provide a governance framework for disaster risk reduction. Different societies face diverse risks and do not necessarily have the same level of local awareness of these risk. To explore the diversity of risks, two sites were selected from the Mediterranean basin, one chosen from the south coast (north Morocco) and the other from the north coast (the Italian island of Sardinia). North Morocco, a region of multi-risks, is characterised by high demographic and economic pressures; west Sardinia has remarkable biodiversity of wetlands and is characterised by high environmental and agricultural pressures, which in both cases intensify the vulnerability of the coastal areas. Testing for the local population's preparedness for future financial protection allowed for discussing the importance of risk awareness sessions or activities as an indicator of risk management. The significance of risk awareness sessions is shown in a quantitative part of the study, and its importance is also discussed with local stakeholders in north Morocco in a qualitative part of the study. It is shown that, although risk awareness sessions are recognised as important in risk management, they are not necessarily implemented. Based on these findings, further ideas on a new series of less descriptive, more dynamic and more user-friendly indicators are suggested. How can risk sessions be a dynamic indicator of a resilient society? The obtained results could serve in future governance frameworks for the mitigation of natural hazards in the Mediterranean region and more widely. Finally, the urgent need for continuous work to overcome the communication gap between the scientific community, risk administrators, civil society and the general population is emphasised.

Fathima; Numair Ahmed Siddiqui; Manoj Mathew; David Menier; Benjamin Sautter; Rajveer Sharma; Pankaj Kumar; Sundeep Chopra; R. Jegankumar;We document evidence for the role of fluvial dynamics-stream channel avulsion and flooding, tectonics and climatic conditions on the occurrence, shifting and burial of ancient cultural sites in the Vaigai River Basin in southern India. Systematic regional mapping, geophysical investigations and archaeological excavations in the flood plains of the Vaigai River led to the unearthing of an ancient culture that thrived at least since 752 BCE (2435 +/- 34 BP). Evidence for early human activities include sites of ancient and now buried industries that were manufacturing steel, glass bead, dye, gold jewelry and earthenware, in addition to dwelling-habitation, sites of religious sacrificial ceremonies, and places of worship, and burial. These information together with the occurrences of microlithic age stone tools in the vicinity led to the proposition of continued habitation of the Vaigai River Basin until today. Radiometric dating shows oldest age of 2435 +/- 34 BP (752 BCE) obtained at 2.5 m depth in a pit excavated at Keezhadi, a location situated far from the present day channel course whereas the youngest age of 689 +/- 24 BP is obtained at Agaram, a location situated nearest to the present day channel course. The bone fragments were dated as 1115 +/- 39 BP (778 CE - 1016 CE) and 1229 +/- 30 BP (689 CE - 883 CE). The organic carbon/peat layers recovered between flood deposits at the upper reaches of the Vaigai River are dated as 830 +/- 30 BP and 1250 +/- 30 BP. The natural levee deposits show evidences of habitation-related disturbances in the internal sedimentary structure, texture and packing. In addition to occurrences of hearth etc., re-currences of overbank-channel deposits over natural levee-habitation surfaces indicate habitation-colonization over relatively highgrounds along river bank, followed by marooning/burial under overbank-channel deposit and abandon -ment of habitation site and/or shifting of habitat. The same sequence of events occurred again, showing two habitation surfaces that are buried under surface currently. Together with facies characteristics and other artifact occurrences, the ages obtained in our study indicate shifting of the Vaigai River from prior to 2435 BP and colonization of ancient population, which might have been affected by a catastrophic flood and stream avulsion at about 1250-830 BP. These resulted in the ancient habitation getting marooned, industries and other structural infrastructure destroyed, and were transported and deposited as interbeds in flood deposits. Following a reduction in the stream energy, the point bar-natural levee environmental setting paved way for the deposition of organic carbon layer at Agaram at about 690 BP. This was followed by lateral shifting of the channel from Agaram towards the present-day course.

Ainsi, en dépit des difficultés posées par les troncs subfossiles en tant qu’objets d’étude, cet article examine les possibilités de reconstitutions des dynamiques fluviales holocènes à partir de ce gisement et interroge les événements hydrologiques dont il peut être la signature. En mettant en perspective l’âge des bois subfossiles (4 individus datés par le radiocarbone) avec celui des sédiments dans lesquels ils sont inclus (7 datations OSL et 1 datation par le radiocarbone) et en nous intéressant à l’orientation des troncs et aux contextes de sédimentation, il apparait que : (1) Les âges des 4 troncs subfossiles datés sont compris entre 8330‑8040 cal BP et 3391‑3235 cal BP, attestant des processus de remaniement et de réenfouissement partiels des macro‑débris ligneux qui composent ce gisement. Le décalage temporel, parfois de plusieurs millénaires, entre l’âge des bois subfossiles et celui des encaissants sédimentaires a permis d’identifier deux hiatus érosifs mis en relation avec le méandrage actif qui caractérise ce cours d’eau durant la seconde moitié de l’Holocène. (2) Les troncs subfossiles ont été observés au sein de deux grands paléochenaux, des bancs sableux et des anciens chenaux de taille plus modeste interprétés comme des bras de chute. Ces environnements de dépôts sont cohérents avec les observations menées sur les bois morts des cours d’eau actuels (chenaux en voie de déconnexion, bancs et îles, pieds de berge). (3) L’examen de l’orientation des troncs traduit un corpus hétérogène. Si des similitudes sont observées, en particulier au sein du banc sableux central, les deux grands paléochenaux contiennent des individus orientés différemment. Ces dispositifs sont mis en relation avec la formation d’embâcles dont il ne resterait que les bois de très grand gabarit. Les facteurs de contrôle, à l’origine de la formation de ce gisement, sont potentiellement multiples. Le retrait de berge ainsi que les paramètres hydro‑climatiques qui le favorisent, sont envisagés comme des facteurs explicatifs pertinents. Cependant, la mort physiologique des végétaux ainsi que les défrichements anthropiques (à l’échelle de la ripisylve et du bassin versant) sont également à prendre en compte. La constitution d’un référentiel régional de troncs subfossiles observés au sein des dépôts fluviatiles et datés pourrait permettre d’améliorer la connaissance de ces facteurs de contrôle. This study focuses on a deposit of sixteen subfossil tree trunks identified within a section of the middle Cher valley (Centre‑Val de Loire region, France) whose sedimentary bodies are well known and dated. Thus, despite the difficulties raised by this type of object of study, this article examines the possibilities of Holocene fluvial dynamics reconstructions based on this deposit and questions the hydrological events of which it can be the signature. By comparing the age of the subfossil wood (4 radiocarbon dated trunks) with that of the sediments in which they are included (7 OSL dates and 1 radiocarbon date) and by examining at the orientation of the trunks and the sedimentation contexts, it appears that: (1) The ages of dated subfossil tree trunks range from 8330‑8040 cal BP to 3391‑3235 cal BP, attesting to the partially reworking and reburial processes of wood debris of this deposit. The time lag, sometimes of several millennia, between the age of the subfossil woods and that of the sedimentary formations allowed the identification of two erosive hiatuses related to the active meandering processes that characterized this river during the second half of the Holocene. (2) The subfossil tree trunks were observed within two large palaeochannels, sandy banks, and smaller former channels interpreted as chute channels. These contexts of deposition are consistent with observations made of large wood debris in present‑day watercourse (disconnecting channels, banks and islands, bank bases). (3) Analysis of the orientation of the trunks reveals a heterogeneous corpus. Although similarities are observed, particularly within the central sandy bank, the two large palaeochannels contain large debris that are oriented differently. These features are related to the formation of woody debris jams, of which only the very large wood remains.The controlling factors of the formation of this deposit, are potentially multiple. Bank retreat as well as hydro‑climatic parameters that favor it, are considered as relevant explanatory factors. However, the physiological death of the tree as well as the human clearings (on the scale of the riparian zone and the catchment area) are also to be taken into account. The constitution of a regional reference system of subfossil tree trunks observed within the fluvial deposits and dated could improve the knowledge of these controlling factors.

This article addresses this shift by examining how everyday practices of technology and space come together in the constitution of coworking spaces (CWS) as pronounced example of where NWW take place. Conceptually, the article links research on technology as sociomaterial practice with literature on the production of space. Empirically, it draws from a qualitative study of 25 CWS and offers a theorization of the co-constitutive processes with relevant insights for both technology and organization studies. First, the article adds to research on the relational and dialectic nature of technology by documenting its implication in the constitution of CWS as site, contestation, and atmosphere. Second, it contributes to existing knowledge on space by shifting the focus from physical sites to spatial atmospheres and vibes that are produced through technology use and the co-presence of bodies. It problematizes engagement with NWW by highlighting how the flexibility to work anytime, anywhere is tied to new responsibilities including spacing work (the creation of productive and social spaces of work) and spatial selfmanagement, which requires workers to aptly navigate different sites and vibes in their quest to achieve personal productivity and affective sociality.

Air quality is a social, economical, and health issue for fast-developing countries such as China. Due to the overuse of nonrenewable energy, industrialization, and the population put pressure on air quality, which seriously threatens public health and economic growth. This study focuses on air quality and also aims to investigate the short-and long-run correlation between foreign direct investment, energy consumption, domestic credit, and financial development. The Autoregressive distributed lag model and the Granger non-causality test were carried out over the period from 1985 to 2018. The main findings of this study show a positive and significant long-run impact of energy consumption on air quality. In addition, domestic credit and financial development similarly show a significant positive short-run association with air quality. Moreover, the unidirectional causality correlation running from foreign direct investment and domestic credit to air quality was concluded by the Granger non-causality test. Considering the empirical analysis, this study suggests that domestic financial institutions should offer credit to industries at a low-interest rate in order to help them to switch from non-renewable to renewable energy consumption towards the promotion of sustainable and healthy air quality.

The aim of the study is to provide an overview of the accident, highlighting the causes and the consequences of this compound disaster. Furthermore, the study analyses the emergency response and clean-up activities in order to identify lessons learned, and propose recommendations for future flood triggered oil spills. The work presented is based on the integration of information available in newspaper articles, government documents and reports, and data and interviews collected during two field trips in the affected area. The permanence of oil and the strong oil odour in adjacent crops as well as on irrigation canals and citizens’ houses was revealed during the first field trip, about one month after the accident. The analysis of the documentation on metal working oil revealed that it might have long-lasting impact in terms of environmental pollution. The presence of oil impacted also the implemented emergency response actions, since vertical evacuation, practiced by many residents during the disaster, actually put many of them in more danger as they ended up trapped in oil-covered floodwaters with strong vapours that were reported to cause nausea and skin irritation. Remarkably, it was also found that a previous oil spill had already occurred at the same site following a severe flooding event, highlighting the need to improve preparedness and develop more effective strategies for accident prevention. Disaster preparedness that specifically considers both the natural hazard and the potential for related technological scenarios should be enhanced, in particular regarding chemical accidents triggered by floods. Japan, as well as other parts of the World, is experiencing stronger rainfall events due to a changing climate leading to unprecedented flooding. Therefore, industry, government and citizens should consider the possibility of an increase of weather-related compound disasters in planning and implementation of climate change adaptation strategies.

Due to its position, connecting northern Europe and the Mediterranean basin, this corridor and the surrounding plateaus are of particular interest in the study of human cultural evolution, including the emergence of Middle Palaeolithic technology around 300,000 years ago and its variability over time, as well as the subsistence and mobility strategies of Neanderthals. In the last 20 years, several research projects undertaken in this region allowed to revise key Middle Palaeolithic sequences. This work aims at synthesising previous and new chronological data obtained by using uranium-series of speleothems and bones, infrared stimulated luminescence of feldspar and electron spin resonance of tooth enamel and quartz. We review previous ages obtained in the area and present 43 new ages that are discussed together to propose a reliable spatiotemporal framework for Neanderthal occupations. We focus on major sites in the region: Payre, Ranc-Pointu 2, Baume Flandin, Abri du Maras, Grotte des Barasses II, Abri des Pêcheurs, Grotte du Figuier and Grotte de Saint-Marcel. They all provided significant information related to the biological and behavioural evolution of Neanderthal populations on the right bank of the Rhône valley. We present here the updated chronology for the Middle Palaeolithic of this area, ranging from ca. 300,000 to 40,000 years ago.

The diachronic analysis of aerial and satellite imagery, uncrewed aerial vehicle (UAV) andin situsurveys obtained between 1956 and 2019 are employed to analyse landform surface kinematics for the Tapado site located in the Dry Andes of Chile. A feature tracking procedure was used between series of orthorectified and co-registered images to calculate surface velocities on several ice-debris landforms, including rock glaciers and debris-covered glaciers. For the active rock glaciers, the results exhibit typical viscous flow, though local destabilisation process seems to occur, increased velocities since 2000 (>1 m/yr) and terminus advance. Nevertheless, the debris-covered glaciers displays heterogeneous spatial patterns of surface velocities, together with collapse (downwasting) associated with the development of thermokarst depressions and supraglacial ponds. Our findings show that surface kinematics and multitemporal observations derived from different sensors are valuable tools for differentiating between glacial and periglacial features. The pluri-decadal time series since 1956 constitute a unique dataset for documenting the surface kinematics of creeping mountain permafrost in the Southern Hemisphere. The approach developed in this work offers a way forward to reconstruct the recent behaviour of glacial and periglacial features in the Andes, where archival aerial photographs are available but have not previously been processed rigorously to obtain an accurate assessment of landform kinematics.

In order to allow the detection of features of interest, visualization filters have to be applied to the raw Digital Elevation Model (DEM), to enhance small relief variations. Several filters have been proposed for this purpose, such as Sky View Factor, Slope, negative and positive Openness, or Local Relief Model (LRM). The efficiency of each of these methods is strongly dependent on the input parameters chosen in regard of the topography of the investigated area. The LRM has proved to be one of the most efficient, but it has to be parameterized in order to be adapted to the natural slopes characterizing the investigated area. Generally, this setting has a single value, chosen as the best compromise between optimal values for each relief configuration. As LiDAR is mainly used in wide areas, a large distribution of natural slopes is often encountered. The aim of this paper is to propose a Self AdaptIve LOcal Relief Enhancer (SAILORE) based on the Local Relief Model approach. The filtering effect is adapted to the local slope, allowing the detection at the same time of low-frequency relief variation on flat areas, as well as the identification of high-frequency relief variation in the presence of steep slopes. First, the interest of this self-adaptive approach is presented, and the principle of the method, compared to the classical LRM method, is described. This new tool is then applied to a LiDAR dataset characterized by various terrain configurations in order to test its performance and compare it with the classical LRM. The results of this test show that SAILORE significantly increases the detection capability while simplifying it.

Abstract Silver played a key role in the progressive monetization of early Mediterranean civilizations. We combine Pb and Ag isotopes with volatile trace elements (Bi, Sb, and As) to assess whether, during the Roman occupation of Iberia, galena constituted a significant source of silver. We find that the Pb and Ag isotopic compositions of 47 samples of galena from eight different Iberian mining provinces, many of them exploited during Roman times, are uncorrelated. This indicates that their respective isotopic variabilities depend on different petrogenetic processes. Moreover, the range of Ag isotopic abundances is approximately six times wider than that displayed worldwide by silver coins in general and Roman silver coins in particular. Although galena from the Betics provides the best fit for Pb isotopes with Roman coins, their fit with Ag isotopic compositions is at best sporadic. We suggest that, together with Sb, Bi, and As, silver is primarily derived from fluids boiled off from differentiated mantle-derived magmas. These fluids, in turn, reacted with preexisting galena and functioned as a silver trap. Lead sulfides with ε109Ag of ~0 and unusually rich in Ag, Sb, Bi, and As were the most probable sources of ancient silver, whereas samples with ε109Ag departing significantly from ~0 reflect low-temperature isotopic fractionation processes in the upper crust.

Supplement: The supplement related to this article is available online at: https://doi.org/10.5194/nhess-21-3749-2021-supplement. Copyright © 2021 The Author(s). In order to mitigate the potentially dramatic effects of natural hazards, risk management measures are critical. However, the lack of interdisciplinary indicators and adaptable governance frameworks highlights society's vulnerability in the particular context of global environmental and climate change. This interdisciplinary research aimed at identifying reliable risk indicators and societal responses regarding natural hazards and climate change impacts to provide a governance framework for disaster risk reduction. Different societies face diverse risks and do not necessarily have the same level of local awareness of these risk. To explore the diversity of risks, two sites were selected from the Mediterranean basin, one chosen from the south coast (north Morocco) and the other from the north coast (the Italian island of Sardinia). North Morocco, a region of multi-risks, is characterised by high demographic and economic pressures; west Sardinia has remarkable biodiversity of wetlands and is characterised by high environmental and agricultural pressures, which in both cases intensify the vulnerability of the coastal areas. Testing for the local population's preparedness for future financial protection allowed for discussing the importance of risk awareness sessions or activities as an indicator of risk management. The significance of risk awareness sessions is shown in a quantitative part of the study, and its importance is also discussed with local stakeholders in north Morocco in a qualitative part of the study. It is shown that, although risk awareness sessions are recognised as important in risk management, they are not necessarily implemented. Based on these findings, further ideas on a new series of less descriptive, more dynamic and more user-friendly indicators are suggested. How can risk sessions be a dynamic indicator of a resilient society? The obtained results could serve in future governance frameworks for the mitigation of natural hazards in the Mediterranean region and more widely. Finally, the urgent need for continuous work to overcome the communication gap between the scientific community, risk administrators, civil society and the general population is emphasised.

Fathima; Numair Ahmed Siddiqui; Manoj Mathew; David Menier; Benjamin Sautter; Rajveer Sharma; Pankaj Kumar; Sundeep Chopra; R. Jegankumar;We document evidence for the role of fluvial dynamics-stream channel avulsion and flooding, tectonics and climatic conditions on the occurrence, shifting and burial of ancient cultural sites in the Vaigai River Basin in southern India. Systematic regional mapping, geophysical investigations and archaeological excavations in the flood plains of the Vaigai River led to the unearthing of an ancient culture that thrived at least since 752 BCE (2435 +/- 34 BP). Evidence for early human activities include sites of ancient and now buried industries that were manufacturing steel, glass bead, dye, gold jewelry and earthenware, in addition to dwelling-habitation, sites of religious sacrificial ceremonies, and places of worship, and burial. These information together with the occurrences of microlithic age stone tools in the vicinity led to the proposition of continued habitation of the Vaigai River Basin until today. Radiometric dating shows oldest age of 2435 +/- 34 BP (752 BCE) obtained at 2.5 m depth in a pit excavated at Keezhadi, a location situated far from the present day channel course whereas the youngest age of 689 +/- 24 BP is obtained at Agaram, a location situated nearest to the present day channel course. The bone fragments were dated as 1115 +/- 39 BP (778 CE - 1016 CE) and 1229 +/- 30 BP (689 CE - 883 CE). The organic carbon/peat layers recovered between flood deposits at the upper reaches of the Vaigai River are dated as 830 +/- 30 BP and 1250 +/- 30 BP. The natural levee deposits show evidences of habitation-related disturbances in the internal sedimentary structure, texture and packing. In addition to occurrences of hearth etc., re-currences of overbank-channel deposits over natural levee-habitation surfaces indicate habitation-colonization over relatively highgrounds along river bank, followed by marooning/burial under overbank-channel deposit and abandon -ment of habitation site and/or shifting of habitat. The same sequence of events occurred again, showing two habitation surfaces that are buried under surface currently. Together with facies characteristics and other artifact occurrences, the ages obtained in our study indicate shifting of the Vaigai River from prior to 2435 BP and colonization of ancient population, which might have been affected by a catastrophic flood and stream avulsion at about 1250-830 BP. These resulted in the ancient habitation getting marooned, industries and other structural infrastructure destroyed, and were transported and deposited as interbeds in flood deposits. Following a reduction in the stream energy, the point bar-natural levee environmental setting paved way for the deposition of organic carbon layer at Agaram at about 690 BP. This was followed by lateral shifting of the channel from Agaram towards the present-day course.

Ainsi, en dépit des difficultés posées par les troncs subfossiles en tant qu’objets d’étude, cet article examine les possibilités de reconstitutions des dynamiques fluviales holocènes à partir de ce gisement et interroge les événements hydrologiques dont il peut être la signature. En mettant en perspective l’âge des bois subfossiles (4 individus datés par le radiocarbone) avec celui des sédiments dans lesquels ils sont inclus (7 datations OSL et 1 datation par le radiocarbone) et en nous intéressant à l’orientation des troncs et aux contextes de sédimentation, il apparait que : (1) Les âges des 4 troncs subfossiles datés sont compris entre 8330‑8040 cal BP et 3391‑3235 cal BP, attestant des processus de remaniement et de réenfouissement partiels des macro‑débris ligneux qui composent ce gisement. Le décalage temporel, parfois de plusieurs millénaires, entre l’âge des bois subfossiles et celui des encaissants sédimentaires a permis d’identifier deux hiatus érosifs mis en relation avec le méandrage actif qui caractérise ce cours d’eau durant la seconde moitié de l’Holocène. (2) Les troncs subfossiles ont été observés au sein de deux grands paléochenaux, des bancs sableux et des anciens chenaux de taille plus modeste interprétés comme des bras de chute. Ces environnements de dépôts sont cohérents avec les observations menées sur les bois morts des cours d’eau actuels (chenaux en voie de déconnexion, bancs et îles, pieds de berge). (3) L’examen de l’orientation des troncs traduit un corpus hétérogène. Si des similitudes sont observées, en particulier au sein du banc sableux central, les deux grands paléochenaux contiennent des individus orientés différemment. Ces dispositifs sont mis en relation avec la formation d’embâcles dont il ne resterait que les bois de très grand gabarit. Les facteurs de contrôle, à l’origine de la formation de ce gisement, sont potentiellement multiples. Le retrait de berge ainsi que les paramètres hydro‑climatiques qui le favorisent, sont envisagés comme des facteurs explicatifs pertinents. Cependant, la mort physiologique des végétaux ainsi que les défrichements anthropiques (à l’échelle de la ripisylve et du bassin versant) sont également à prendre en compte. La constitution d’un référentiel régional de troncs subfossiles observés au sein des dépôts fluviatiles et datés pourrait permettre d’améliorer la connaissance de ces facteurs de contrôle. This study focuses on a deposit of sixteen subfossil tree trunks identified within a section of the middle Cher valley (Centre‑Val de Loire region, France) whose sedimentary bodies are well known and dated. Thus, despite the difficulties raised by this type of object of study, this article examines the possibilities of Holocene fluvial dynamics reconstructions based on this deposit and questions the hydrological events of which it can be the signature. By comparing the age of the subfossil wood (4 radiocarbon dated trunks) with that of the sediments in which they are included (7 OSL dates and 1 radiocarbon date) and by examining at the orientation of the trunks and the sedimentation contexts, it appears that: (1) The ages of dated subfossil tree trunks range from 8330‑8040 cal BP to 3391‑3235 cal BP, attesting to the partially reworking and reburial processes of wood debris of this deposit. The time lag, sometimes of several millennia, between the age of the subfossil woods and that of the sedimentary formations allowed the identification of two erosive hiatuses related to the active meandering processes that characterized this river during the second half of the Holocene. (2) The subfossil tree trunks were observed within two large palaeochannels, sandy banks, and smaller former channels interpreted as chute channels. These contexts of deposition are consistent with observations made of large wood debris in present‑day watercourse (disconnecting channels, banks and islands, bank bases). (3) Analysis of the orientation of the trunks reveals a heterogeneous corpus. Although similarities are observed, particularly within the central sandy bank, the two large palaeochannels contain large debris that are oriented differently. These features are related to the formation of woody debris jams, of which only the very large wood remains.The controlling factors of the formation of this deposit, are potentially multiple. Bank retreat as well as hydro‑climatic parameters that favor it, are considered as relevant explanatory factors. However, the physiological death of the tree as well as the human clearings (on the scale of the riparian zone and the catchment area) are also to be taken into account. The constitution of a regional reference system of subfossil tree trunks observed within the fluvial deposits and dated could improve the knowledge of these controlling factors.

This article addresses this shift by examining how everyday practices of technology and space come together in the constitution of coworking spaces (CWS) as pronounced example of where NWW take place. Conceptually, the article links research on technology as sociomaterial practice with literature on the production of space. Empirically, it draws from a qualitative study of 25 CWS and offers a theorization of the co-constitutive processes with relevant insights for both technology and organization studies. First, the article adds to research on the relational and dialectic nature of technology by documenting its implication in the constitution of CWS as site, contestation, and atmosphere. Second, it contributes to existing knowledge on space by shifting the focus from physical sites to spatial atmospheres and vibes that are produced through technology use and the co-presence of bodies. It problematizes engagement with NWW by highlighting how the flexibility to work anytime, anywhere is tied to new responsibilities including spacing work (the creation of productive and social spaces of work) and spatial selfmanagement, which requires workers to aptly navigate different sites and vibes in their quest to achieve personal productivity and affective sociality.

Air quality is a social, economical, and health issue for fast-developing countries such as China. Due to the overuse of nonrenewable energy, industrialization, and the population put pressure on air quality, which seriously threatens public health and economic growth. This study focuses on air quality and also aims to investigate the short-and long-run correlation between foreign direct investment, energy consumption, domestic credit, and financial development. The Autoregressive distributed lag model and the Granger non-causality test were carried out over the period from 1985 to 2018. The main findings of this study show a positive and significant long-run impact of energy consumption on air quality. In addition, domestic credit and financial development similarly show a significant positive short-run association with air quality. Moreover, the unidirectional causality correlation running from foreign direct investment and domestic credit to air quality was concluded by the Granger non-causality test. Considering the empirical analysis, this study suggests that domestic financial institutions should offer credit to industries at a low-interest rate in order to help them to switch from non-renewable to renewable energy consumption towards the promotion of sustainable and healthy air quality.

The aim of the study is to provide an overview of the accident, highlighting the causes and the consequences of this compound disaster. Furthermore, the study analyses the emergency response and clean-up activities in order to identify lessons learned, and propose recommendations for future flood triggered oil spills. The work presented is based on the integration of information available in newspaper articles, government documents and reports, and data and interviews collected during two field trips in the affected area. The permanence of oil and the strong oil odour in adjacent crops as well as on irrigation canals and citizens’ houses was revealed during the first field trip, about one month after the accident. The analysis of the documentation on metal working oil revealed that it might have long-lasting impact in terms of environmental pollution. The presence of oil impacted also the implemented emergency response actions, since vertical evacuation, practiced by many residents during the disaster, actually put many of them in more danger as they ended up trapped in oil-covered floodwaters with strong vapours that were reported to cause nausea and skin irritation. Remarkably, it was also found that a previous oil spill had already occurred at the same site following a severe flooding event, highlighting the need to improve preparedness and develop more effective strategies for accident prevention. Disaster preparedness that specifically considers both the natural hazard and the potential for related technological scenarios should be enhanced, in particular regarding chemical accidents triggered by floods. Japan, as well as other parts of the World, is experiencing stronger rainfall events due to a changing climate leading to unprecedented flooding. Therefore, industry, government and citizens should consider the possibility of an increase of weather-related compound disasters in planning and implementation of climate change adaptation strategies.

Price; Monique Pierre; Arnaud Dapoigny; Christophe Falguères; Olivier Tombret; Pierre Voinchet; Jean-Jacques Bahain; Marie-Hélène Moncel;International audience; The middle Rhône valley, located at the southeastern margins of the Massif Central in France, produced a large number of Middle Palaeolithic sites, most of which dated to the Middle and Late Pleistocene. Due to its position, connecting northern Europe and the Mediterranean basin, this corridor and the surrounding plateaus are of particular interest in the study of human cultural evolution, including the emergence of Middle Palaeolithic technology around 300,000 years ago and its variability over time, as well as the subsistence and mobility strategies of Neanderthals. In the last 20 years, several research projects undertaken in this region allowed to revise key Middle Palaeolithic sequences. This work aims at synthesising previous and new chronological data obtained by using uranium-series of speleothems and bones, infrared stimulated luminescence of feldspar and electron spin resonance of tooth enamel and quartz. We review previous ages obtained in the area and present 43 new ages that are discussed together to propose a reliable spatiotemporal framework for Neanderthal occupations. We focus on major sites in the region: Payre, Ranc-Pointu 2, Baume Flandin, Abri du Maras, Grotte des Barasses II, Abri des Pêcheurs, Grotte du Figuier and Grotte de Saint-Marcel. They all provided significant information related to the biological and behavioural evolution of Neanderthal populations on the right bank of the Rhône valley. We present here the updated chronology for the Middle Palaeolithic of this area, ranging from ca. 300,000 to 40,000 years ago.

The diachronic analysis of aerial and satellite imagery, uncrewed aerial vehicle (UAV) andin situsurveys obtained between 1956 and 2019 are employed to analyse landform surface kinematics for the Tapado site located in the Dry Andes of Chile. A feature tracking procedure was used between series of orthorectified and co-registered images to calculate surface velocities on several ice-debris landforms, including rock glaciers and debris-covered glaciers. For the active rock glaciers, the results exhibit typical viscous flow, though local destabilisation process seems to occur, increased velocities since 2000 (>1 m/yr) and terminus advance. Nevertheless, the debris-covered glaciers displays heterogeneous spatial patterns of surface velocities, together with collapse (downwasting) associated with the development of thermokarst depressions and supraglacial ponds. Our findings show that surface kinematics and multitemporal observations derived from different sensors are valuable tools for differentiating between glacial and periglacial features. The pluri-decadal time series since 1956 constitute a unique dataset for documenting the surface kinematics of creeping mountain permafrost in the Southern Hemisphere. The approach developed in this work offers a way forward to reconstruct the recent behaviour of glacial and periglacial features in the Andes, where archival aerial photographs are available but have not previously been processed rigorously to obtain an accurate assessment of landform kinematics.

In order to allow the detection of features of interest, visualization filters have to be applied to the raw Digital Elevation Model (DEM), to enhance small relief variations. Several filters have been proposed for this purpose, such as Sky View Factor, Slope, negative and positive Openness, or Local Relief Model (LRM). The efficiency of each of these methods is strongly dependent on the input parameters chosen in regard of the topography of the investigated area. The LRM has proved to be one of the most efficient, but it has to be parameterized in order to be adapted to the natural slopes characterizing the investigated area. Generally, this setting has a single value, chosen as the best compromise between optimal values for each relief configuration. As LiDAR is mainly used in wide areas, a large distribution of natural slopes is often encountered. The aim of this paper is to propose a Self AdaptIve LOcal Relief Enhancer (SAILORE) based on the Local Relief Model approach. The filtering effect is adapted to the local slope, allowing the detection at the same time of low-frequency relief variation on flat areas, as well as the identification of high-frequency relief variation in the presence of steep slopes. First, the interest of this self-adaptive approach is presented, and the principle of the method, compared to the classical LRM method, is described. This new tool is then applied to a LiDAR dataset characterized by various terrain configurations in order to test its performance and compare it with the classical LRM. The results of this test show that SAILORE significantly increases the detection capability while simplifying it.
