Available in PDF, EPUB and Kindle. Book excerpt: Les actes de ces journées font état de réflexions, tant en France qu'à l'étranger, sur la restauration de marais, d'estuaires, de baies et de lagunes, incluant l'incidence sur les espèces et ressources. L'ouvrage regroupe une sélection des communications présentées devant un public de scientifiques, enseignants, aménageurs professionnels de la mer et conservateurs du littoral. Y sont présentés quelques grands chantiers (lagunes de Venise et de Tunis, baie du Mont-Saint-Michel, estuaire de Seine...), ainsi que des réalisations de tailles et de natures diverses. Des aspects particuliers de la biorestauration sont abordés au travers du traitement biologique des vases, ou celui des pollutions par hydrocarbures. Les aspects technico-économiques s'appuient sur des exemples accidentels ou naturels. Les aménageurs et les sociétés d'ingénierie écologique pourront trouver, dans ces documents, critères et méthodes d'évaluation scientifique pour quantifier les coûts de restauration d'écosystèmes en fonction de l'importance des " dégâts ".
Book Synopsis Seagrasses: Biology, Ecology and Conservation by : Anthony W. D. Larkum
Download or read book Seagrasses: Biology, Ecology and Conservation written by Anthony W. D. Larkum and published by Springer Science & Business Media. This book was released on 2007-05-16 with total page 691 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seagrasses are unique plants; the only group of flowering plants to recolonise the sea. They occur on every continental margin, except Antarctica, and form ecosystems which have important roles in fisheries, fish nursery grounds, prawn fisheries, habitat diversity and sediment stabilisation. Over the last two decades there has been an explosion of research and information on all aspects of seagrass biology. However the compilation of all this work into one book has not been attempted previously. In this book experts in 26 areas of seagrass biology present their work in chapters which are state-of–the-art and designed to be useful to students and researchers alike. The book not only focuses on what has been discovered but what exciting areas are left to discover. The book is divided into sections on taxonomy, anatomy, reproduction, ecology, physiology, fisheries, management, conservation and landscape ecology. It is destined to become the chosen text on seagrasses for any marine biology course.

Book Synopsis The Land-Sea Interactions by : André Monaco
Download or read book The Land-Sea Interactions written by André Monaco and published by John Wiley & Sons. This book was released on 2014-12-03 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a systemic view of the diversity of pressures and impacts produced by climate change and human actions. Erosion of biodiversity by changing ocean chemistry, the intensification of global change raises the problem of the adaptation of living resources. Land uses induce ecological imbalances leading to asphyxiation true coastal ecosystems. More than a billion tons of solid waste must be assimilated by the marine environment and food webs. Radioactive discharges emitted into the atmosphere or into the aquatic environment, raise the question of their future. Sea and Ocean series offers a transversal approach of the ocean system that leads to governance, sustainable resource management and adaptation of societies.
Book Synopsis The Ecology of Invasions by Animals and Plants by : Charles S. Elton
Download or read book The Ecology of Invasions by Animals and Plants written by Charles S. Elton and published by Springer Nature. This book was released on 2020-03-10 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elton sought to articulate more explicitly his vision of an entire field of invasion science. The 1958 book, aimed at an educated lay audience, was almost wholly descriptive, dominated by striking examples of the nature and scope of particular invasions beginning with the seven examples detailed in Chapter 1. From the materials in the proof copy and other sources, we can imagine a new edition would also have targeted biologists and been somewhat more technical and prescriptive. In autobiographical notes he penned near the end of his life, Elton wrote regarding EIAP, “This whole subject has deep significance for the study of plant and animal communities and their balance (or unbalance),”19 and indeed many of the reprints and notes refer to interactions among species and community-wide effects.

Book Synopsis Integrated Coastal Zone Management of Coral Reefs by : Kent Gustavson
Download or read book Integrated Coastal Zone Management of Coral Reefs written by Kent Gustavson and published by World Bank Publications. This book was released on 2000 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The applied research indicates that, to improve awareness, park education programs should be targeted specifically to the user groups primarily through outreach programs. Further, the Park's management programs should be highlighted, particularly the beneficial, tangible products and services (benefits) the Park provides to each user group... The closer the tie between reef conditions and business earnings, the greater the users' support for reef conservation." Coral reefs are sometimes referred to as "canaries of the sea" because of their early warning ability to show near-shore oceanic stress. Because of their biological diversity, they are also called "rainforests of the sea." Coral reefs are vital to the well being of millions of people. Coral reef managers and government officials trying to save their valuable national resources have turned to research on coral reefs for help. The research presented in this publication merits a great deal of notice because the output is useful for decision support and training tools in integrated coastal zone management (ICZM). The work on cost-effectiveness analysis has developed integrated economic and ecological models, relying extensively on fuzzy logic procedures to model impacts and effects of interventions within the reef environment. By contrast, the marine system valuation work provides economic valuations of coral reefs, demonstrating the use of different modeling methods and treating key policy issues within this context. This publication will interest coastal zone experts and managers worldwide

This book was released on 2022-10-28 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dams are planned, constructed, and operated to meet human needs - generation of energy, irrigated agricultural production, flood control, public and industrial supply, supply of drinking water, and various other purposes. Dams impound water in reservoirs during times of high flood that can be used for human requirements during times with inadequate natural flows. Positive impacts of dams are improved flood control, improved welfare resulting from new access to irrigation and drinking water. Without dams there would be insufficient food to feed the world’s people and energy would be generated by burning fossil fuels that produce greenhouse gases. Despite this progress there remain significant concerns about the environmental impacts of dams. These environmental impacts are complex and far reaching, remote of the dam, and may occur in time with the dam construction or later and may lead to a loss of biodiversity and of productivity of natural resources. This bulletin compiles improvements in knowledge and state of the art technology to avoid or mitigate environmental impacts of dams on the natural ecosystem as well as to the people that depend upon them for their livelihood and also addresses the mitigation of environmental impacts on dams and reservoirs. Les barrages sont planifiés, construits et exploités de manière à répondre aux besoins humains. Les barrages retiennent l'eau dans les réservoirs pendant les périodes de forte crue, une eau qui peut être utilisée pour les besoins de l'homme pendant les périodes d’insuffisance des débits naturels. Les impacts positifs de barrages sont le contrôle des crues et l'amélioration du bien-être résultant du nouvel accès à l'irrigation et à l'eau potable. Sans barrages, la production alimentaire serait insuffisante pour nourrir la population du globe et l'énergie serait générée en brûlant des combustibles fossiles qui produisent des gaz à effet de serre. Malgré ces progrès, d'importantes préoccupations subsistent quant aux retombées des barrages sur l’environnement. Les impacts environnementaux sont complexes et d’une grande portée. Ils peuvent se produire au moment de la construction du barrage ou plus tard et peuvent entraîner une perte de la biodiversité et de la productivité des ressources naturelles. Le présent bulletin compile l'amélioration des connaissances et des technologies les plus récentes pour éviter ou atténuer les impacts environnementaux des barrages sur l'écosystème naturel ainsi que pour les personnes qui en dépendent pour leur subsistance. Il aborde également l'atténuation des impacts environnementaux sur les barrages et les réservoirs.

Book Synopsis Valuation of marine and estuarine coastal ecosystem services in the Canary Current large marine ecosystem region / Évaluation des services écosystémiques marins côtiers et estuariens dans la région du grand écosystème marin du courant des Canaries by : Food and Agriculture Organization of the United Nations
Download or read book Valuation of marine and estuarine coastal ecosystem services in the Canary Current large marine ecosystem region / Évaluation des services écosystémiques marins côtiers et estuariens dans la région du grand écosystème marin du courant des Canaries written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-10-04 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecosystem valuation is a process that assigns a monetary value to the benefits that are provided by an ecosystem and its ecosystem services. This study carries out the economic valuation of marine and estuarine coastal ecosystem services in the Canary Current Marine Ecosystem (CCLME). The CCLME stretches along the coast of Western Africa, from Morocco to Guinea, and is characterized by high biological productivity due to the upwelling of deep, cold oceanic waters along this coast. This also supports a high abundance of fish resources (both pelagic and demersal) and overall high biodiversity. This study reviews and assesses ecosystem services provided by the marine areas, coastal mangroves and seagrass meadows. These coastal areas not only provide habitats for some commercial fish species, but also feeding grounds, nurseries, or refuges. Therefore, mangroves and seagrasses can play an important role in maintaining fish stocks. L’évaluation des écosystèmes est un processus qui attribue une valeur monétaire aux avantages offerts par un écosystème et ses services écosystémiques. Cette étude cherche à réaliser une évaluation économique des services des écosystèmes côtiers marins et estuariens dans l’écosystème marin du courant des Canaries (CCLME). Le CCLME s’étend le long des côtes de l’Afrique de l’Ouest, du Maroc à la Guinée, et se caractérise par une productivité biologique élevée due à la remontée d’eaux océaniques froides et profondes (upwelling) le long de cette côte. Cela favorise également une grande abondance de ressources halieutiques (pélagiques et démersales) et une biodiversité globale élevée. Cette étude examine et évalue les services écosystémiques fournis par les zones marines, les mangroves côtières et les herbiers marins. Ces zones côtières fournissent non seulement des habitats pour certaines espèces de poissons commerciales, mais constituent également des aires d’alimentation, de nourriceries ou des refuges. Par conséquent, les mangroves et les herbiers marins peuvent jouer un rôle important dans le maintien des stocks de poissons.
