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.

Book Description
Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

Book Description
Past progress and future challenges R.J. Wheater Royal Zoological Society of Scotland, Edinburgh, UK. In the past two decades much has been achieved in the sphere of breeding endangered species, and we should be pleased that our co operative efforts have already borne so much fruit. However, on balance and despite the best efforts of conservationists, the position of wildlife in the wild places where they are best conserved has become worse, often dramatically worse. Before returning to the United Kingdom in 1972, I was in Uganda for 16 years, most of which time was spent as Chief Warden of Murchison Falls National Park. Our main problem was that an over-population of large mammals was having a devastating impact on the habitat. Devas tation was being wrought on woodland areas by the arrival of large numbers of elephants into the sanctuary of the Park, following changes in land use in the areas outside the Park. These changes were in response to the requirements of an ever-expanding human population.

Book Description
World Bank Discussion Paper No. 337. Draws on household survey data from 87 rural villages in Bangladesh to examine the contribution that government family planning programs, as well as other health care interventions, have made toward the recent reduction in fertility by increasing contraceptive use and reducing infant mortality. The paper suggests that the programs have been effective and finds that targeted credit program placement, such as the Grameen Bank and the Bangladesh Rural Advancement Committee (BRAC), contributed to the effort as well.

Book Description
The Pan-European Biological and Landscape Diversity Strategy, which was endorsed by ministers from 54 countries in the UN-ECE region on 25 October 1995, provides for the establishment by 2005 of the Pan-European Ecological Network. These Guidelines provide a reference document for all those involved in establishing and managing the network. The document aims to provide a coherent framework for guiding an array of co-operative, decentralised measures which aim to ensure the conservation and sustainable use of the ecosystems, habitats, species and landscapes of European importance.

Book Description
For most British natural historians, there is one vertebrate order that could well be said to be “out of sight, out of mind.” This is our freshwater fishes, familiar principally only to anglers, those concerned with managing rivers and other waterbodies, and a few research scientists. The results of this project, which ran from 1998-2002, are published here in the form of comprehensive 10km square dot-distribution maps for the 54 species inhabiting England, Scotland, Wales, the Channel Islands and the Isle of Man. These indicate the vulnerability of several of our native British species. Following a wide-ranging introductory chapter, and further chapters on distribution and the history of the project, Chapter 4 comprises the individual species accounts under the headings: Description; Biology and behaviour; Habitat; Distribution in Britain; World distribution; Status; Hybrids and related species; and a final section of the relationship of each species with Man. In addition to a map, each species is illustrated by fine lithographs taken from Francis Day's famous 19th century work, skilfully supplemented by Michael J. Roberts for those species unknown to Day. Chapter 5 covers conservation and management of freshwater fishes and is followed by four Appendices relating to (1) Publications; (2 & 3) Legislation; and (4) Selected websites relating to environmental protection, biodiversity information and fish conservation. The book concludes with a Glossary; a comprehensive Bibliography; and an Index. In his Foreword, Sir John Burnett, Chairman of the National Biodiversity Network Trust, commends this books as “a unique reliable source of clear and comprehensive information that is pleasing both to the mind and to the eyes” and expresses the hope that “it will lead to ... the more effective conservation of this ‘alien race’ in our midst.” A joint project of the Environment Agency, the Centre for Ecology and Hydrology and the Joint Nature Conservation Committee; written by a team of 38 authors and compiled and edited by Cynthia Davies (CEH), Jonathan Shelley (EA), Paul Harding (Biological Records Centre, CEH), Ian McLean (JNCC), Ross Gardiner (Fisheries Research Services) and Graeme Peirson (EA).
