Book Description
In this age of increased fundamental and applied research on biodiversity, no single volume was as yet devoted to the various temporal and spatial aspects of aquatic biodiversity. The present book is published in honour of Professor Henri Dumont (Ghent, Belgium) at the occasion of his retirement as Editor-in-Chief of Hydrobiologia. The volume presents a selection of contributions on aquatic biodiversity, written by colleagues from the editorial board, fellow editors of aquatic journals and former students and collaborators. Contributions deal with a wide spectrum of topics related to aquatic biodiversity and cover fields such as actual- and palaeolimnology, taxonomy, and fundamental and applied limnology. Even reconnaissance chapters on management and cultural impact of water bodies are included. The book combines state-of-the-art contributions in aquatic sciences.
Conservation of Endangered Freshwater Fish in Europe
Author: Arthur KirchhoferPublisher: Birkhäuser
ISBN: 3034890141
Category : Science
Languages : en
Pages : 340
Book Description
Two events have recently improved the prospects of protecting fish and their environment in Switzerland: the acceptance of a new Federal Water Protection Law in the plebiscite of May 17th 1992, and the new Federal Legislation on Fisheries, in force since January 1st 1994. With this legal framework, the possibilities for protection of nature and landscape have now considerably improved in Switzerland. The most important aims of the Federal Law on Water Protection are to safeguard the natural habitats of the native flora and fauna and water as the habitat of aquatic organisms. This includes not only the preservation or restoration of water quality in lakes and rivers, but also, in rivers used for hydroelectricity, irrigation or as industrial or other water supplies, the maintenance of sufficient water to fulfill the minimal requirements for fish. However, good quality water in sufficient quan tities alone is not enough to guarantee the survival of fish. Intact fish habitats comprise various phYsical structures including plenty of hiding places, hunting grounds, reproduction and nursery areas within suitable distances from each other. This third aspect of conservation and restoration of aquatic habitats is a central point in the new Federal Law on Fisheries. Whereas the former versions of this law were more concerned with fishery regulations, the recent legislation defines new areas of responsibility for the federal and the cantonal governments.

The River Basin in History and Law
Author: Ludwik A. TeclaffPublisher: Springer Science & Business Media
ISBN: 9401510253
Category : Law
Languages : en
Pages : 249
Book Description
Fresh water is one of man's most vital needs. The distribution of water within river basins has a direct bearing on the organization of water resources development to meet this ever-expanding need. River basins, despite their very great diversity in other respects, have one physical characteristic in common: each is a more or less self-contained unit within whose bounds all the surface and part or all of the ground waters form an interconnected, interdependent system. This inter dependence has such far-reaching implications - for pollution and flood control, apportionment of supply, relations between upstream and downstream riparians, to mention only a few examples - that the river basin has become almost universally accepted (within the past 20 or 30 years at least) as the unit of optimal water resources de velopment. Professor Teclaff's work (which was originally submitted to the New York University School of Law as a doctoral dissertation) is the first fully developed response to the important resolution passed by the International Law Association at its New York meeting in I958 recognizing the legal nature of the international river basin. His study quite properly, therefore, poses the question whether the adoption of the river basin unit is a temporary phenomenon, reflecting the current stage of technology and of administrative, economic, and legal thought on water resources development, or whether the de terminative influence of the river basin's physical unity which has always operated in the past will continue to operate in the future.
