Book Synopsis The Status and Distribution of Freshwater Biodiversity in Central Africa by : E. G. E. Brooks
Download or read book The Status and Distribution of Freshwater Biodiversity in Central Africa written by E. G. E. Brooks and published by IUCN. This book was released on 2011 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main reasons cited for inadequate representation of biodiversity in the development processes is a lack of readily available information on inland water taxa. In response to this need for basic for information on species, the IUCN Species Programme conducted a regional assessment of the status and distribution of 2,261 taxa of freshwater fishes, molluscs, odonates, crabs and selected families of aquatic plants from throughout central Africa. This study is based on the collation and analysis of existing information, and the knowledge of regional experts.
Book Synopsis Biodiversity Erosion by : Christian Lévêque
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.

Available in PDF, EPUB and Kindle. Book excerpt: Ce manuel pratique aide à comprendre les grands principes régissant la morphologie des cours d’eau et leur dynamique pour mieux concevoir des aménagements qui sauront résister aux crues sans déséquilibrer pour autant les écosystèmes. Le chapitre 1 donne les définitions, principes de base et résultats d’hydraulique à surface libre. Les chapitres 2 à 4 approfondissent le diagnostic des rivières en tenant compte du transport solide et de la constante interaction entre l’écoulement, le fond, les berges et le champ d’inondation. Les chapitres 5 à 9 exposent les différents aménagements et entretiens pour utiliser l’eau ou se protéger des crues. Cette 2e édition, entièrement réactualisée et augmentée de nombreux schémas et photos, aborde de nouveaux points : les calculs hydrauliques des déversoirs latéraux, des estimations de débit solide adaptées aux fortes pentes, la morphologie des torrents et les conséquences morphologiques des barrages, la restauration morphologique des rivières, les processus d’érosion par surverse, la conception des zones d’expansion de crues, des procédés de protection de berge ou de traitement des digues, la nouvelle norme sur les enrochements, etc... Diagnostic, aménagement et gestion des rivières s’adresse aux professionnels en charge de la gestion et de l’aménagement des cours d’eau ou de la police de l’eau : cabinets d’ingénierie, collectivités territoriales, établissements publics, sociétés d’aménagement régional et services déconcentrés et centraux de l’État. Il sera une aide précieuse pour les étudiants en écoles d’ingénieur ou en université et intéressera les chercheurs en mécanique des fluides, géomorphologie ou écologie fluviale.

Download or read book Research Anthology on Ecosystem Conservation and Preserving Biodiversity written by Management Association, Information Resources and published by IGI Global. This book was released on 2022-04-08 with total page 1915 pages. Available in PDF, EPUB and Kindle. Book excerpt: In today’s rapidly evolving world, it has never been more critical to consider key environmental issues such as climate change, pollution, and endangered species. Society faces an unknown future where the fate of the environment is continuously in flux based on current preservation initiatives that governments develop. In order to ensure the world is protected moving forward, further study on the importance of securing environments, ecosystems, and species is necessary to successfully implement change. The Research Anthology on Ecosystem Conservation and Preserving Biodiversity considers the best practices and strategies for protecting our current ecosystems as well as the potential ramifications of failing to implement policies. Society is at a crossroads where if we continue to ignore the danger and warning signs brought about by environmental issues, we will be unable to maintain a healthy environment. Covering essential topics such as extinction, climate change, and pollution, this major reference work is ideal for scientists, industry professionals, researchers, academicians, policymakers, scholars, practitioners, instructors, and students.
Book Synopsis Dams and Water Transfers – An Overview / Barrages et Transferts d’Eau - Aperçu by : Cigb Icold
Download or read book Dams and Water Transfers – An Overview / Barrages et Transferts d’Eau - Aperçu written by Cigb Icold and published by CRC Press. This book was released on 2021-08-09 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present Bulletin presents a complete response from the ‘Technical Committee of ICOLD on Dams and Water Transfer (CDWT)’ to the Terms of Reference. It starts with related global information, brings out related efforts made in countries with completely differing climate, economy, population distribution etc. about present status within and between river basins & countries – both surplus and or deficit, while recognizing the crucial role played by dams in water transfer to needy regions. It then enumerates guidelines followed in considering various options, while identifying geographical issues, limited by political territories & legal issues like water treaties. Essentially then, it dwells on possible need, potential and problems in water transfers that must be handled to overcome B/C issues faced by needy countries. In order to assist concerned professionals, the Bulletin finally elaborates on objections raised by different stake-holders in the subject and provides answers generated globally. The on-going debate world-over about WRD versus environmental impacts is then dealt with to help Member-countries overcome various issues. Le présent Bulletin présente une réponse complète du « Comité Technique sur les barrages et les transferts d’eau ». Il commence par des informations mondiales, fait ressortir les efforts déployés dans des pays au climat, à l'économie, à la répartition de la population, etc. complètement différents sur l'état actuel au sein et entre les bassins fluviaux et les pays - à la fois excédentaire et / ou déficitaire, tout en reconnaissant le rôle crucial joué par les barrages dans le transfert d'eau vers les régions nécessiteuses. Il énumère ensuite les lignes directrices suivies pour considérer diverses options, tout en identifiant les problèmes géographiques, limités par les territoires politiques et les questions juridiques comme les traités sur l'eau. Essentiellement, il s'attarde donc sur les besoins, le potentiel et les problèmes possibles des transferts d'eau qui doivent être traités pour surmonter les problèmes auxquels sont confrontés les pays dans le besoin. Afin d'aider les professionnels concernés, le Bulletin élabore enfin les objections soulevées par les différents acteurs du sujet et apporte des réponses générées globalement. Le débat en cours dans le monde entier par rapport aux impacts environnementaux est ensuite traité pour aider les pays membres à surmonter divers problèmes.

Book Synopsis Coastal Wetlands: Alteration and Remediation by : Charles W. Finkl
Download or read book Coastal Wetlands: Alteration and Remediation written by Charles W. Finkl and published by Springer. This book was released on 2017-07-18 with total page 879 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book delves into human-induced and natural impacts on coastal wetlands, intended or otherwise, through a series of vignettes that elucidate the environmental insults and efforts at amelioration and remediation. The alteration, and subsequent restoration, of wetland habitats remain key issues among coastal scientists. These topics are introduced through case studies and pilot programs that are designed to better understand the best practices of trying to save what is left of these fragile ecosystems. Local approaches, as well as national and international efforts to restore the functionality of marsh systems are summarily approached and evaluated by their efficacy in producing resilient reclamations in terms of climate-smart habitat conservation. The outlook of this work is global in extent and local by intent. Included here in summarized form are professional opinions of experts in the field that investigate the crux of the matter, which proves to be human pressure on coastal wetland environments. Even though conservation and preservation of these delicate environmental systems may be coming at a later date, many multi-pronged approaches show promise through advances in education, litigation, and engineering to achieve sustainable coastal systems. The examples in this book are not only of interest to those working exclusively with coastal wetlands, but also to those working to protect the surrounding coastal areas of all types.

Book Synopsis The Baseline Concept in Biodiversity Conservation by : Laurent Godet
Download or read book The Baseline Concept in Biodiversity Conservation written by Laurent Godet and published by John Wiley & Sons. This book was released on 2022-09-20 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Anthropocene era has been marked by such significant human pressure that it has led to the sixth mass extinction. The Baseline Concept in Biodiversity Conservation interprets human domination of the Earth as the process of gradual landscape change, the execution of which is neither linear nor homogeneous. This book is structured around three key questions: Where and when did everything go wrong? How do we define baseline states for biodiversity conservation strategies? How are reference states mobilized in a concrete way through case studies? Today, biodiversity conservation faces a dilemma that this book sheds light on: return to states less modified by humans than today but in a world that has changed significantly; or, let the nature of tomorrow express itself where it still can but without a road map.
Book Synopsis Freshwater key biodiversity areas in the Mediterranean basin hotspot by : V. Barrios
Download or read book Freshwater key biodiversity areas in the Mediterranean basin hotspot written by V. Barrios and published by IUCN. This book was released on 2014-01-01 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the Mediterranean basin biodiversity hotspot is well known for its globally important biodiversity, its freshwater biodiversity has not been as widely recognized for its importance. Through this project, freshwater key biodiversity areas (KBAs) have now been identified, mapped and validated throughout much of the Mediterranean hotspot. It is now important to raise awareness of their status as validated freshwater KBAs and to develop plans for appropriate conservation actions at these sites, as this biodiversity is highly threatened largely due to the conflicting demands upon a diminishing supply of fresh water which is further exacerbated by the increased severity of drought across the region.
