Book Description
In the mid 1970s two events led me to get to know the Yorkshire Dales better than I had previously. Since 1964 I had been to the Malham Tarn Field Centre with groups of students, first from the University of Edinburgh and then from the University of York, and my family very much enjoyed the summer days we spent amid this magnificent hill scenery. In 1976, the British Ecological Society and the National Trust jointly worked on a survey of the biological interest of the National Trust properties of the Kent, East Anglian and Yorkshire Regions. Malham Tarn itself, and the surrounding farms, formed one of the twenty properties of the Yorkshire Region. I spent the bank holiday, that commemorated the Queen's Silver Jubilee, at Malham, looking fairly closely at the National Trust's landholding there. Miss Sarah Priest, who also looked at the National Trust properties, and I produced a report in late 1977, attempting both to describe and to evaluate the nature resources of the National Trust in Yorkshire. In the following year, 1978, the Nature Conservancy Council wanted to survey the whole of the upland area that was known as the Malhaml Arncliffe SSSI (Site of Special Scientific Interest). A contract to look at such an exciting area, considering where boundaries should go, and looking to see if there were important areas of habitat that should be brought within the SSSI, was a superb practical antidote to an office in the University.

Book Description
How to Build a Digital Library reviews knowledge and tools to construct and maintain a digital library, regardless of the size or purpose. A resource for individuals, agencies, and institutions wishing to put this powerful tool to work in their burgeoning information treasuries. The Second Edition reflects developments in the field as well as in the Greenstone Digital Library open source software. In Part I, the authors have added an entire new chapter on user groups, user support, collaborative browsing, user contributions, and so on. There is also new material on content-based queries, map-based queries, cross-media queries. There is an increased emphasis placed on multimedia by adding a "digitizing" section to each major media type. A new chapter has also been added on "internationalization," which will address Unicode standards, multi-language interfaces and collections, and issues with non-European languages (Chinese, Hindi, etc.). Part II, the software tools section, has been completely rewritten to reflect the new developments in Greenstone Digital Library Software, an internationally popular open source software tool with a comprehensive graphical facility for creating and maintaining digital libraries. - Outlines the history of libraries on both traditional and digital - Written for both technical and non-technical audiences and covers the entire spectrum of media, including text, images, audio, video, and related XML standards - Web-enhanced with software documentation, color illustrations, full-text index, source code, and more

Book Description
Scenes of starvation have drawn the world's attention to Africa's agricultural and environmental crisis. Some observers question whether this continent can ever hope to feed its growing population. Yet there is an overlooked food resource in sub-Saharan Africa that has vast potential: native food plants. When experts were asked to nominate African food plants for inclusion in a new book, a list of 30 species grew quickly to hundreds. All in all, Africa has more than 2,000 native grains and fruitsâ€""lost" species due for rediscovery and exploitation. This volume focuses on native cereals, including: African rice, reserved until recently as a luxury food for religious rituals. Finger millet, neglected internationally although it is a staple for millions. Fonio (acha), probably the oldest African cereal and sometimes called "hungry rice." Pearl millet, a widely used grain that still holds great untapped potential. Sorghum, with prospects for making the twenty-first century the "century of sorghum." Tef, in many ways ideal but only now enjoying budding commercial production. Other cultivated and wild grains. This readable and engaging book dispels myths, often based on Western bias, about the nutritional value, flavor, and yield of these African grains. Designed as a tool for economic development, the volume is organized with increasing levels of detail to meet the needs of both lay and professional readers. The authors present the available information on where and how each grain is grown, harvested, and processed, and they list its benefits and limitations as a food source. The authors describe "next steps" for increasing the use of each grain, outline research needs, and address issues in building commercial production. Sidebars cover such interesting points as the potential use of gene mapping and other "high-tech" agricultural techniques on these grains. This fact-filled volume will be of great interest to agricultural experts, entrepreneurs, researchers, and individuals concerned about restoring food production, environmental health, and economic opportunity in sub-Saharan Africa.

Book Description
In developing countries, traditional fermentation serves many purposes. It can improve the taste of an otherwise bland food, enhance the digestibility of a food that is difficult to assimilate, preserve food from degradation by noxious organisms, and increase nutritional value through the synthesis of essential amino acids and vitamins. Although "fermented food" has a vaguely distasteful ring, bread, wine, cheese, and yogurt are all familiar fermented foods. Less familiar are gari, ogi, idli, ugba, and other relatively unstudied but important foods in some African and Asian countries. This book reports on current research to improve the safety and nutrition of these foods through an elucidation of the microorganisms and mechanisms involved in their production. Also included are recommendations for needed research.
