Available in PDF, EPUB and Kindle. Book excerpt: This l:::ook comes as part of a new series on Solar Energy R+D, includlng Biomass which is carried out by the Euro:pean Community.. The commission of the European Comrmmities' Directorate General (XII) for Science, Research and Developnent is currently implementing, on a cost-sharing basis, a solar energy R+D pro;Jranune through contracts with European industry, research institutions and uni versi ties. This prcgrarrrrne includes a very strong acti vi ty on Biomass. Besides general R+D work on all aspects of Biomass growth and utilization which is reported elsewhere in this series, the Canmission is currently starting a new activity on Pilot Plants based on the use of Biomass for energy purp:Jses, and in particular on methanol prcx:luction from wood. The commission considers that the subject of methanol prcxiuction from wood offers llnp:Jrtant prospects for application wi thin the European Canmilllity and in other parts of the world, in particular some of the developing countries & The state of art in Europe In this field is still considered to be very high as a result of related work which was performed in Europe during ~vorld War II and the time before.

Book excerpt: The Group assessed the status of the small pelagic resources in Northwest Africa and make projections on the development of the status of the stocks and on future effort and catch levels. As a precautionary measure, the catch level for this species should not exceed the average over the last three years of 115 000 tonnes.

Download or read book Les ailes du Sahel written by Le Zwarts and published by BRILL. This book was released on 2014-04-14 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Living on the Edge' examines the function of the Sahel region of Africa as an important wintering area for long-distance migrant birds. It describes the challenges the birds have to cope with – climate change, of course, and rapid man-made habitat changes related to deforestation, irrigation and reclamation of wetlands. How have all these changes affected the birds, and have birds adapted to these changes? Can we explain the changing numbers of breeding birds in Europe by changes in the Sahel, or vice versa? Winner of the BB/BTO Best Bird Book Award 2010 The Jury commented: "It is a tremendous book in every department. It marks a step-change in our knowledge of the ecology of this critically important region in the European-African migration system and of the many species (familiar to us on their breeding grounds) that winter there. The authors combine the latest scientific information with vivid descriptions of landscapes and animals. Their book is richly illustrated with large numbers of drawings, maps and photographs by acclaimed experts. The wealth of coloured graphics has been particularly well thought out and encourages readers to delve into the figures and learn more about the region, rather than having the (all-too-common) opposite effect. Summing up, the jury praises not just the high quality of the texts, the information and the illustrations, but also the sheer pleasure of reading the book: "One of the key attributes of a good book is to be able to grip the reader's attention and transport him or her to another place. We feel confident that [Living on the edge] will have that effect."

This book was released on 2019-07-17 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fourth meeting of the FAO/CECAF Working Group on the Assessment of Small Pelagic Fish – Subgroup South was held in Elmina, Ghana from 12-20 September 2018. The overall objective of the Working Group is to contribute to the improved management of small pelagic resources in West Africa through the assessment of the state of the stocks and fisheries in order to ensure sustainable use of these resources for the benefit of coastal countries. The species assessed by the Working Group were: sardinella (Sardinella aurita and Sardinella maderensis), bonga (Ethmalosa fimbriata), anchovy (Engraulis encrasicolus) and horse mackerel (Trachurus trecae and Decapterus rhonchus), and other Carangidae, in the region between the northern border of Guinea-Bissau and the southern border of Angola. La quatrième réunion du Groupe de travail FAO/COPACE sur l’évaluation des petits pélagiques – Sous-groupe Sud, s’ets tenue à Elmina, Ghana, du 12 au 20 septembre 2018. L’objectif général du Groupe de travail est d’améliorer la gestion des ressources en petits pélagiques en Afrique de l’Ouest grâce à l’évaluation de l’état des stocks et des pêcheries de façon à assurer une utilisation durable de ces ressources au bénéfice des pays côtiers. Les espèces évaluées par le Groupe de travail sont les suivantes: les sardinelles (Sardinella aurita et t Sardinella maderensis), l’ethmalose (Ethmalosa fimbriata), l’anchois (Engraulis encrasicolus) et les chinchards (Trachurus trecae et Decapterus rhonchus) et autres carangidés, dans la région située entre la frontière nord de la Guinée-Bissau et la frontière sud de l’Angola.
Download or read book Atlantic Halibut Hippoglossus Hippoglossus and Pacific Halibut H Stenolepis and Their North American Fisheries written by Robert J. Trumble and published by NRC Research Press. This book was released on 1993 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlantic halibut and Pacific halibut off the Atlantic and Pacific coasts of North America share many biological characteristics. The conventional separation of the halibut into separate species is not uniformly accepted. Reproduction and early life history are nearly identical, although the extensive drift of Pacific halibut eggs and larvae and countermigration as juveniles have not been demonstrated for the Atlantic halibut. Adult halibut undergo migration from winter spawning grounds along the upper continental slope to summer feeding grounds on the continental shelf. The two halibuts show the same pattern of age and growth. They exhibit different trophic selectivity, as small Atlantic halibut consume a higher proportion of invertebrates as samll fish and large Atlantic halibut consume a higher proportion of fish, compared to Pacific halibut. Halibut management in the Atlantic and Pacific varies dramatically. Atlantic halibut in Canada were managed with other groundfish until 1988 and are not managed in the United States. Pacific halibut have been managed by an international commission under treaty between the United States and Canada since 1923. Atlantic halibut have produced from 1000 to 5000 t annually, mainly off Canada, while Pacific halibut have produced 12,000 to 45,000 t, mainly off Alaska. Biological and fishery data are collected more extensively for the Pacific halibut, for which detailed stock assessment is conducted.
