"River restoration has expanded exponentially in the last three decades, with increased investment by government agencies, private developers, and NGOs. The available literature -- both scholarly works and government guidance manuals -- has grown proportionately, but has been almost entirely about ecological, hydrological, and geomorphological aspects of restoration. Yet the primary issues faced by many restoration programs have more to do with legal, economic, and institutional barriers and public perception and acceptance, than with physical and ecological constraints (though these can be formidable as well). Diverse issues such as the installation of habitat structures and replanting along a small creek by a local group, or a major program to restore complex habitat, a more natural flow regime, and sediment supply to a river below a dam, require an understanding of the social dimensions of river restoration projects. For anyone funding, permitting, planning, designing, or building river restoration projects, a concise, up-to-date, clearly organized treatment of the critical socio-economic issues relevant to river restoration will be a very useful asset. Most people involved in restoration projects (ecologists, engineers, landscape architects, hydrologists) lack a strong background in the social sciences. Increasingly however, these professionals understand that they must consider social dimensions. This book will fill a critical gap in their libraries summarizing how social approaches can contribute to river restoration projects and policies. The aim of this book is to present and synthesize understanding from recent advances in social sciences related to river restoration. It will cover not only supposedly "intangible" social phenomena -- such as ethics, culture and justice -- but also very tangible practical aspects -- including policy, governance, project management, decision making and stakeholder interactions -- to give a complete picture of the sometimes complex interaction of issues in river restoration."--

Les bois flottants sont une source de nuisances, mais leurs bienfaits écologiques sont aujourd'hui également démontrés. La législation et l'environnement socioculturel demeurent des freins à un renouveau de leur gestion. Cette étude montre que le bois mort reste négativement valorisé dans l'imaginaire collectif. Il importe d'en prendre conscience lorsque des décisions dites rationnelles doivent être prises en matière de gestion des rivières aménagées.

International audience We present a datalogger based on Arduino cards and commercially available tools for radio frequency identification, which we term the e-RFIDuino. Designed to be robut, easy to build and install, it detects and records the mobility of objects tagged with active transponders emitting in the ultra-high frequency domain (433.5 MHz). It functions without connection to the power supply network and is adapted to harsh outdoor environments. Once installed in the field and its on-site sensing field is determined, the data collected (timestamp of detection, transponder identification number, and received signal strength indication) allow estimation of the virtual velocity of tracer passage and investigation of displacement patterns at the scale of the area of detection. Experimental tests showed the device to have very high effectiveness when used to monitor the passage of sediment tracers in a torrential river system during various flood events over several months. The total cost to construct this open source device is below 850 Euros, and it is easily customizable. In the future, it could be equipped with a system for data transmission over the mobile telephone network to reduce the field effort and time required to obtain data, and to provide real-time triggering of field acquisitions at the most appropriate times

International audience ; Riverscapes are constructs that mix natural components with political, socioeconomic, and technicalstrategies. This article shows how the riverscapes of the Rh^one in France have changed under the influenceof different power relations. We use newspapers to highlight the potential of news outlets as a data sourcewith which to apply Foucault's critical and genealogical methods and to develop a political ecology ofsocioecological fixes. Media coverage is proxied by a content analysis and textual data analysis of 1,079articles published in Le Monde from 1945 to 2013. We study variations of newspaper discourse to create fivechronological narratives: (1) the reconstruction of France and the creation of new landscapes, (2) thepromotion of national development through navigation, (3) the quest for energy independence throughdams and nuclear power plants, (4) the abandonment of major projects, and (5) the definition of pollutionand flooding as national problems at the same time as the rediscovery of landscapes as local amenities. Riverlandscapes are related to national political objectives, even though schemes for the Rh^one seem to be everless geared to national ambitions. In specific contexts, bottom-up advocacy coalitions occasionally provepowerful enough to influence socioecological trajectories: Their power seems to be on the rise as thenational project wanes. They are often opposed to new socioecological fixes. Although political drivers areinstrumental in shaping the Rh^one, economic dynamics are crucial. Energy production seems to be a goodindicator for monitoring socioecological fixes along major rivers because it involves fixed capital.
