Book Synopsis Écosystèmes aquatiques by : Christian Lévêque
Download or read book Écosystèmes aquatiques written by Christian Lévêque and published by . This book was released on 1996 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'eau stockée dans les lacs, les rivières et les zones humides ne représente qu'une part infime des eaux de la planète. Pourtant ces milieux sont indispensables à la vie de très nombreuses espèces végétales et animales, y compris l'Homme. Les systèmes aquatiques continentaux sont bien structurés. Les communautés végétales et animales s'organisent le long des gradients physico-chimiques : gradient longitudinal pour les fleuves, profondeur pour les lacs. Le régime hydrologique est le véritable moteur du fonctionnement écologique de ces hydrosystèmes qui sont en forte interaction avec les milieux environnants. Ces hydrosystèmes font l'objet, partout dans le monde, de nombreux usages qui sont en forte interaction avec les milieux environnants. Pourtant ceux-ci constituent un véritable patrimoine écologique qu'il faut préserver. La notion de gestion intégrée prend en compte la complexité des interactions entre les systèmes écologiques et les systèmes sociaux. Une perspective de développement durable est nécessairement un compromis entre la protection des milieux et les enjeux économiques et sociaux dont ils font l'objet.

Book Synopsis Les Eaux continentales by : Ghislain de Marsily
Download or read book Les Eaux continentales written by Ghislain de Marsily and published by EDP Sciences. This book was released on 2012-12-03 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce rapport apporte un éclairage sur les difficultés que nos sociétés sont susceptibles de rencontrer dans le domaine de l'eau, à court, moyen et long terme, en France et dans le reste du monde. Les difficultés envisagées concernent les insécurités ou crises liées au manque d'eau, aux excès d'eau et à la détérioration de la qualité de l'eau et des écosystèmes aquatiques. L'analyse de ces difficultés potentielles, dont tout le monde pressent que les conséquences pourraient être dramatiques, l'analyse de leur probabilité d'occurrence et de leur échelonnement dans le temps ont pour objet de tenter, par l'action, de les prévenir, ou, si elles survenaient, d'en amoindrir les effets. Deux causes principales de ces difficultés sont mises en avant : - l'effet des changements démographiques, qui vont vraisemblablement faire croître la population de 6 à 9 milliards d'êtres humains d'ici 2050 et faire passer le taux d'urbanisation de 50 % à 80 %. La question de l'eau - production alimentaire, adduction d'eau potable et assainissement - y est centrale ; - l'effet des changements climatiques liés aux émissions de gaz à effets de serre, qui auront une incidence progressive sur les situations moyennes, mais agiront aussi sur les événements extrêmes (crues, sécheresse) dont les fréquences sont susceptibles de varier notablement. Le rapport aborde les problèmes de ressources en eau, de production alimentaire, d'écosystèmes, de qualité de l'eau et de risques d'inondation. Ces questions sont examinées selon six grands thèmes : bilan besoins-ressources à l'échelle mondiale et alimentation ; gestion des eaux à l'échelle régionale des bassins versants ; l'eau à l'échelle locale des grandes mégalopoles ; écosystèmes aquatiques ; eau et santé ; eau et climat. Le rapport formule enfin des recommandations, tant sur les actions publiques préventives à mener, à caractère réglementaire ou économique, que sur les actions de recherche ou acquisitions de connaissances nouvelles à programmer.

Book Synopsis Evolution of Marine Coastal Ecosystems under the Pressure of Global Changes by : Hubert-Jean Ceccaldi
Download or read book Evolution of Marine Coastal Ecosystems under the Pressure of Global Changes written by Hubert-Jean Ceccaldi and published by Springer Nature. This book was released on 2020-06-15 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal and estuarine environments at the interface of terrestrial and marine areas are among the most productive in the world. However, since the beginning of the industrial era, these ecosystems have been subjected to strong anthropogenic pressures intensified from the second half of the 20th century, when there was a marked acceleration in the warming (climate change) of the continents, particularly at high latitudes. Coastal ecosystems are highly vulnerable to alteration of their physical, chemical and biological characteristics (marine intrusion, acidification of marine environments, changes in ecosystems, evolution and artificialization of the coastline, etc.).In contact with heavily populated areas, these environments are often the receptacle of a lot of chemical and biological pollution sources that significantly diminish their resilience. In this context of accelerated evolution and degradation of these areas important for food security of many populations around the world, it is necessary to better identify the factors of pressure and understand, at different scales of observation, their effects and impacts on the biodiversity and on the socio-eco-systems, in order to determine the degree of vulnerability of these coastal ecosystems and the risks they face. A transdisciplinary and integrated approach is required to prevent risks. Within this framework, operational coastal oceanography occupies an important place but also the implementation of a true socio-eco-system approach in order to set up an environmentally friendly development.
Book Synopsis L'Albanie dans l'Europe préhistorique by : Gilles Touchais
Download or read book L'Albanie dans l'Europe préhistorique written by Gilles Touchais and published by Ecole Francaise d'Athenes. This book was released on 2002 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inaugurant une nouvelle serie destinee a accueillir les travaux menes par l'Ecole francaise d'Athenes en collaboration avec l'Institut archeologique de l'Academie des sciences d'Albanie, ce volume reunit les communications prononcees lors d'un colloque consacre a la prehistoire de l'Albanie replacee dans son cadre europeen. Cette rencontre, qui a rassemble une quinzaine de chercheurs de diverses nationalites, avait en effet pour principal objectif de consacrer le desenclavement de l'archeologie albanaise au terme d'un demi-siecle de quasi-autarcie. Ce desenclavement etant concu du double point de vue geographique et methodologique, l'accent a ete mis sur deux aspects: d'une part, l'etude des rapports culturels entre l'Albanie et les regions voisines aux epoques prehistoriques; d'autre part, le profit scientifique tire de son ouverture actuelle a la collaboration internationale et aux problematiques de l'archeologie moderne. Plusieurs auteurs de ce recueil s'efforcent ainsi de demeler le faisceau de relations unissant l'Albanie aux cultures de l'Egee, des Balkans, de l'Europe centrale, voire de l'Italie, entre le Neolithique et le debut de l'Age du Fer. D'autres apportent un eclairage nouveau sur la prehistoire albanaise, tantot a travers les donnees inedites de fouilles recentes - notamment celles que la Mission franco-albanaise du bassin de Korce mene sur le site de Sovjan depuis une dizaine d'annees avec le concours de l'EFA -, tantot en renouvelant l'approche methodologique de documents deja connus. Ce volume offre donc a la fois une mise au point sur la prehistoire de l'Albanie dans ses rapports avec les aires culturelles proches ou moins proches et un apercu des perspectives ouvertes par le formidable essor que connaissent les recherches archeologiques dans ce pays depuis une decennie.
