Available in PDF, EPUB and Kindle. Book excerpt: Ce livre est une critique raisonnée des choix que des services de l'État ont fait au début des années 2000 pour mettre en oeuvre la Directive cadre européenne sur l'eau, dont l'idée générale est de supprimer les obstacles dans les cours d'eau pour faciliter le transit sédimentaires et permettre la migration des poissons. Selon les auteurs, cette politique n'est pas fondée sur une connaissance suffisante des rivières. Après une présentation du dispositif législatif et réglementaire, l'ouvrage plaide pour une politique prenant davantage en compte la complexité et les dynamiques dans le cadre du changement climatique en cours. Pour une "gestion apaisée", ils prônent également un véritable dialogue avec les habitants et les usagers pour réellement réfléchir collectivement aux meilleurs choix, la continuité écologique n'étant qu'un des aspects de la gestion des rivières.

Available in PDF, EPUB and Kindle. Book excerpt: « Ce livre, écrit à plusieurs plumes, est une critique raisonnée des choix que des services de l'État ont fait au début des années 2000 pour mettre en oeuvre la Directive cadre européenne sur l'eau. La "continuité sédimentaire et écologique", réalisée par la suppression des seuils en rivière, a directement affecté le patrimoine des moulins, y compris les outils de production énergétique. Cette politique n'est pas fondée sur une connaissance suffisante des rivières, tant en ce qui concerne le transport des sédiments que la mobilité des espèces piscicoles. Elle conduit à des interventions inutiles et parfois contre-productives. Après une présentation du dispositif législatif et réglementaire, celle des concepts naturalistes modernes souligne que la référence à retenir pour la restauration des rivières doit prendre en compte le fonctionnement des systèmes et de nouvelles formes de biodiversité. L'ouvrage plaide pour une politique prenant davantage en compte la complexité et les dynamiques dans le cadre du changement climatique en cours. Enfin, dans un pays qui a connu une longue histoire, les héritages économiques et culturels à l'échelle des bassins versants sont une partie importante du paysage des rivières et ne peuvent être niés. Le patrimoine hydraulique est essentiel aux particuliers qui en ont fait l'objectif d'une vie, comme aux collectivités qui en font un élément très important de leur identité culturelle et économique. Il ne sera pas possible d'avoir une "gestion apaisée" sans adopter un véritable dialogue avec les habitants et les usagers pour réellement réfléchir collectivement aux meilleurs choix, la continuité écologique n'étant qu'un des aspects de la gestion des rivières. Un livre important sur l'eau, l'écologie, les territoires. »--
Download or read book Biodiversity Erosion written by Christian Lévêque and published by John Wiley & Sons. This book was released on 2022-08-19 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The erosion of biodiversity is currently highly publicized. Militant movements accuse humans of destroying nature and being responsible for a sixth mass extinction. However, this anxiety-provoking message is sometimes based on misconceptions, false or partisan ideas, and media relays that favor and amplify alarmist information. If the situation of certain populations is worrying, it is not a general phenomenon because others are expanding. Rather than holding a globalizing discourse, it is necessary to recontextualize and relativize the debate to better define the necessary actions. Biodiversity Erosion analyzes numerous scientific publications, as well as alarming discussions, emphasizing the multiple biases present in the way information is presented. This book questions the relevance of the notion of species and the desire to compile an inventory of all living things. It argues for a less Manichean approach to our relationship with nature.

Download or read book River Contracts and Integrated Water Management in Europe written by Maria Laura Scaduto and published by Springer. This book was released on 2016-08-08 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to stimulate new thinking on the roles of river contracts in the protection and management of hydrographic resources and ecosystems and in the sustainable development of dependent territories and communities. Up-to-date information is provided on a range of topics relating to river contracts, including their relevance to implementation of the EU Water Framework Directive on integrated river basin management. The importance of river contracts for innovation in territorial planning and governance is explored with the aid of comparative analysis between France and Italy that encompasses water management policies, legislative frameworks, contents and procedures, and stakeholder rules and participation. This analysis is supported by enlightening case studies in urbanized and rural contexts within the two countries. The book will be of high interest for all who wish to understand the potential of river contracts to create innovative forums for dialogue and knowledge sharing between public/private stakeholders and local communities and to prompt a new form of governance of river ecosystems and territories that is compliant with the subsidiarity principle.

Download or read book Large scale dam removal and ecosystem restoration written by Rebecca McCaffery and published by Frontiers Media SA. This book was released on 2024-09-20 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rivers are vital ecosystems that support aquatic and terrestrial biodiversity and several ecosystem services, including food, water, culture, and recreation. After centuries of building dams on rivers across the world, dam removal projects are now on the rise due to obsolescence, reservoir sedimentation, insufficient return on investment, or river restoration and conservation priorities. Most dam removal projects have focused on smaller structures (< 10 m in structural height), but larger structures have also started to be removed in increasing numbers as practitioners, river managers, conservationists, and the public have gained more experience with the practice. Recent estimates suggest that only a small fraction of dam removals have been scientifically studied, and include mostly small dams and short time scales. Documenting the long-term ecological outcomes of large dam removal (i.e. >10 m tall) represents a new frontier in dam removal research: projects are more recent and provide an opportunity to understand the complex ecological changes that occur with these transformative restoration projects. Here, we aim to collate a diverse array of papers on long-term dam removal research projects involving larger dams (>10 m) to synthesize the issues, outcomes, tools, and experimental designs used to study large dam removal projects from physical, biological, and ecological perspectives. With this collection, we aim to showcase diverse global projects on ecosystem responses to large dam removal; collect perspectives from different disciplines, fields, and geographies; and synthesize the current state of knowledge in this area. We expect that this Research Topic will be informative to ongoing, long-term ecological restoration and monitoring projects related to dam removal as well as to upcoming large dam removal projects. We welcome contributions from all disciplines addressing the physical, ecological, and ecosystem responses to large-scale dam removal. Contributions could include original research in a specific discipline or area, case studies, or synthesis papers that address one or more of these topics in a transdisciplinary approach. Contributors could address any of the following major topics as related to outcomes of large dam removal, alone or in combination: Freshwater, estuarine, and marine aquatic biota; River and reservoir geomorphology; Terrestrial and riparian vegetation; Wildlife; Sedimentation; and Modelling. We would like contributors to highlight key results in their area of study, cross-disciplinary insights, and lessons learned that could inform ongoing monitoring and research efforts in current projects as well as upcoming large dam removals.

Download or read book Biologie des poissons d eau douce europ ens 2e d written by BRUSLÉ Jacques and published by Lavoisier. This book was released on 2013-07-01 with total page 802 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biologie des poissons d’eau douce européens, par son champ d’étude vaste et ambitieux, est un ouvrage de référence en ichtyologie dulçaquicole. Couvrant l’ensemble des aspects écologiques, écobiologiques, écophysiologiques et éthologiques, il dresse une présentation détaillée de 88 espèces auto- ou allochtones : morphologie, anatomie, distribution géographique, habitats, modes de vie et activités physiologiques. 453 autres espèces sont également répertoriées. Cette 2e édition a été largement revue et augmentée, compte tenu de l’importance des données scientifiques récentes. Outre des compléments utiles portant sur les habitats et les modes de vie, cet ouvrage s’enrichit des nombreux apports génétiques qui ont parfois « révolutionné » les concepts anciens relatifs aux origines paléo-historiques et paléo-géographiques des espèces. Des extensions ou des réductions de répartitions géographiques ont été consécutives à des transferts d’origine anthropique, à des dégradations physiques et chimiques et à la récente influence du Global Warming, sans oublier les changements de statut dans le domaine de la systématique. Au fil d’un livre d’une grande rigueur scientifique, abondamment illustré (dont 64 aquarelles originales et plus de 70 cartes géographiques pertinentes) et complété par un glossaire et une importante bibliographie, le lecteur abordera la connaissance des poissons européens d’une façon à la fois originale et attrayante. Cet ouvrage s’adresse à un large public : étudiants de 2e et 3e cycles en biologie, zoologie, écologie, hydrobiologie, environnement, ingénieurs et techniciens chargés de l’aménagement, de la gestion, de la qualité et de la protection des milieux aquatiques (services vétérinaires, de l’Environnement, de l’Agriculture, de l’Équipement…) auxquels il apportera les bases fondamentales nécessaires à leur action, et plus largement tous les passionnés d’ichtyofaune.

Download or read book The Seine River Basin written by Nicolas Flipo and published by Springer Nature. This book was released on 2021-01-30 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book reviews the water-agro-food and socio-eco-system of the Seine River basin (76,000 km2), and offers a historical perspective on the river’s long-term contamination. The Seine basin is inhabited by circa 17 million people and is impacted by intensive agricultural practices and industrial activities. These pressures have gradually affected its hydrological, chemical and ecological functioning, leading to a maximum chemical degradation between the 1960s and the 1990s. Over the last three decades, while major water-quality improvements have been observed, new issues (e.g. endocrine disruptors, microplastics) have also emerged. The state of the Seine River network, from the headwaters to estuary, is increasingly controlled by the balance between pressures and social responses. This socio-ecosystem provides a unique example of the functioning of a territory under heavy anthropogenic pressure during the Anthropocene era. The achievements made were possible due to the long-term PIREN Seine research program, established in 1989 and today part of the French socio-ecological research network “Zones Ateliers”, itself part of the international Long-term Socio-economic and Ecological Research Network (LTSER). Written by experts in the field, the book provides an introduction to the water budget and the territorial metabolism of the Seine basin, and studies the trajectories and impact of various pollutants in the Seine River. It offers insights into the ecological functioning, the integration of agricultural practices, the analysis of aquatic organic matter, and the evolution of fish assemblages in the Seine basin, and also presents research perspectives and approaches to improve the water quality of the Seine River. Given its scope, it will appeal to environmental managers, scientists and policymakers interested in the long-term contamination of the Seine River.
