This book was released on 2012-12-06 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: The future of the Common Fisheries Policy depends on progress in the relevant areas of research. This applies to the whole range of management decisions, where precise, reliable and complete data are essential to inform those who must decide on the pursuit of existing activities, especially in the area of maritime fisheries, and the development of promising new activities such as aquaculture. Every day the Director-General of DG XIV requires more and more information to prepare decisions which will affect the future of all those in the Community who are dependent on fishing and aquaculture. There is thus a high level of direct demand from DG XIV. Over and above this immediate and specific requirement for short- and medium-term applications, research affects the competitivity of the Community. This is one area which favours the collaboration across frontiers of all those who seek to advance knowledge. But although DG XIV is uniquely placed to appreciate the importance of research into fisheries and aquaculture, there is no question of succumbing to the temptation to directly control the scope of research or its conduct. The notion of subsidiarity can best be understood by examining the existing structures in the Member States. The Commission must act first and foremost as a catalyst, by promoting the circulation of information and the coordination of research programmes.
Download or read book Effects of Riverine Inputs on Coastal Ecosystems and Fisheries Resources written by and published by Food & Agriculture Org.. This book was released on 1995 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five chapters are presented which address a number of aspects of riverine and runoff effects on coastal marine systems. Examples are presented and documented in which the apparent effects of runnoff-related nutrient enrichment and consequent eutrophication have been important. Various other aspects, such as sedimentation, etc. are explored. The purpose is to advance the scientific, policy, and political dialogue on issues related to utilization and protection of coastal marine ecosystems. The "Marine Catchment Basin" or "MCB" appears to be the logical scale of policy and management interest wherever terrestrial runoff has substantial impacts on a marine system. The MCB expands the "marine ecosystem" concept to include not only the marine aquatic system, but also the adjacent land areas that drain into it. The MCB concept has been identified primarily with semi-enclosed seas, where effects have been particularly dramatic and where the "catchment basin" retains an easily visualized geological context. However, even along open ocean coasts, hydrodynamic processes act to retain coherent masses of water, together with their contained organisms and materials, against the coast. Thus open coastal areas may exhibit MCB features similar to those of enclosed or semi-enclosed basins

This book was released on 2004 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document contains the Report and papers presented at the Regional Workshop on Networking for Improved Access to Fisheries and Aquaculture Information in Africa, which was held in Grahamstown, South Africa, from 3 to 7 November 2003. Eighteen participants from Ghana, Guinea, Kenya, Malawi, Mauritania, Nigeria, Seychelles and South Africa attended the Workshop and presented papers. Fisheries library networking activities were reviewed as a basis for planning future collaboration to improve access to fisheries information and to promote information resources sharing. The summary of priority issues includes improved dissemination of African fisheries publications, full-text online fisheries journals, open source software, network focal points, the use of standard methodologies to enhance information exchange and technology for document delivery. The long-term goal of the network is to strengthen the information capacity at national fisheries institutions in Africa.--Publisher's description.
Download or read book Remote Sensing of the African Seas written by Vittorio Barale and published by Springer. This book was released on 2014-06-02 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The African Seas include marginal basins of two major oceans, the Atlantic and the Indian, a miniature ocean, the Mediterranean Sea, and an infant ocean, the Red Sea. Understanding the wide spectrum of environmental features and processes of such a varied collection of marine and coastal regions requires that in situ observation systems be integrated and actually guided, by the application of orbital remote sensing techniques. This volume reviews the current potential of Earth Observations to help in the exploration of the marginal seas around Africa, by virtue of both passive and active techniques, working in several spectral ranges – i.e. measuring either reflected visible and near-infrared sunlight, as well as surface emissions in the thermal infrared and microwave spectral regions, or again the surface reflection of transmitted lidar or radar impulses of visible or microwave radiation. The in-depth evaluation of the advantages offered by each technique and spectral region and in particular by the development of advanced multi-technique systems, contributes to the assessment of the abundant natural resources that the Seas of Africa have to offer, of those in dear need of being – sustainably – exploited and of others that should be protected and maintained in their still pristine conditions.

Download or read book Environment in Key Words written by Isaac Paenson and published by Elsevier. This book was released on 2016-06-28 with total page 978 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems ignore international boundaries. Toxic wastes travel by water and air, sometimes displacing the effects of an environmental disaster entirely outside of its country of origin. It is now understood that to overcome the problems that face us international co-operation is required. This important work is designed to assist in that process, by helping to break down the language barriers that stand between countries. The manual, written in parallel English, German, French and Russian texts, provides the basic tools of communication in the specialized fields of environmental sciences between speakers of these languages. Each chapter has been revised in each separate language by specialists in the field to guarantee the authenticity of the information presented. The author is unique in his approach, presenting the key-words in context, as opposed to simple glossary entries, allowing the reader to fully understand the complex relations between the word and the concepts involved. A comprehensive index written in all four languages guides the reader through the text, providing references to the words as they are used in different disciplines.

This book was released on 2013-10-22 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principles and Methods for Determining Ecological Criteria on Hydrobiocenoses is a collection of papers presented at the 1975 European Scientific Colloquium on Principles and Methods for Determining Ecological Criteria on Hydrobiocenoses, held in Luxembourg. This Colloquium aims to define a scientific basis for assessing the results of pollution on aquatic fauna and flora, as well as the biological methods to be used in assessing the extent of such pollution. This book is organized into four parts encompassing 29 chapters. After a brief overview of a series of parameters for the specific uses of different water classifications and regional evaluation of water pollution, this book goes on examining the ecological consequences of water pollution establishment of criteria and the ecological variable and their effect on aquatic fauna. These topics are followed by a discussion of the value of aquatic plants in water quality characterization, as well as the principles of the methods used. The succeeding parts highlight the concepts and practical methods used in the biological monitoring of surface waters. These parts particularly consider the benefits of using bioindicators and laboratory bioassays. The concluding discusses a comparative study of biological-ecological water assessment methods of water quality. This book will be of value to environmental scientists, engineers, and researchers.
