Download or read book Biodiversity and Domestication of Yams in West Africa written by Roland Dumont and published by Editions Quae. This book was released on 2006-07-17 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of yam domestication practices among smallholders has provided an insight into how farmers exploit wild plant genetic resources so as to adapt them to agriculture. This book describes the domestication operations leading to Dioscorea rotundata yams in Africa. The biodiversity of these yams and of their wild relatives is investigated, and the authors put forward hypotheses to explain the phenotypic changes resulting from smallholder practices. These hypotheses could be possible lines of research for breeders.

Book excerpt: Yam in West Africa examines a crop that has been sidelined and ignored for too long while being central to the existence of so many and consumed worldwide. Though the crop can attract high prices, too often its producers live in penury. Nweke investigates problems of labor, technology, and agronomy in the West African yam industry in hopes of bettering the future of the yam and those who produce and eat it.

Available in PDF, EPUB and Kindle. Book excerpt: This report is the second in a series of three evaluating underexploited African plant resources that could help broaden and secure Africa's food supply. The volume describes the characteristics of 18 little-known indigenous African vegetables (including tubers and legumes) that have potential as food- and cash-crops but are typically overlooked by scientists and policymakers and in the world at large. The book assesses the potential of each vegetable to help overcome malnutrition, boost food security, foster rural development, and create sustainable landcare in Africa. Each species is described in a separate chapter, based on information gathered from and verified by a pool of experts throughout the world. Volume I describes African grains and Volume III African fruits.

Download or read book Les ignames sauvages d Afrique de l Ouest written by Perla Hamon and published by Balogh Scientific Books. This book was released on 1995 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perla Hamon, docteur ès-sciences naturelles, maître de conférence à l'université Montpellier-II, a consacré dix années de recherches sur les ignames de l'Afrique de l'Ouest. Roland Dumont, ingénieur agronome au Cirad, a travaillé pendant plus de vingt ans sur l'igname au Bénin, au Burkina Faso et en Côte d'ivoire. Jeanne Zoundjihekpon, docteur ès-sciences naturelles, a consacré huit années de recherches sur l'igname à l'Université nationale d'Abidjan. Bakary Tio-Touré, docteur ès-sciences naturelles, professeur de génétique à l'Université nationale Côte d'ivoire, a été responsable du programme " Igname " à la Faculté des sciences et techniques d'Abidjan de 1974 à 1992. Il est ambassadeur de Côte d'ivoire auprès de l'Unesco depuis 1992. Serge Hamon, docteur ès-sciences naturelles, directeur de recherche à l'Orstom, responsable du laboratoire LRGAPT, a favorisé une étroite collaboration Orstom-Fast dans le cadre du programme " Igname " aussi bien à Abidjan qu'à Montpellier. En Afrique, le rôle des plantes dites mineures (non importantes dans l'économie mondiale) est fondamental car, en permettant une diversification des cultures, elles contribuent à assurer l'autosuffisance alimentaire. L'igname est une de ces plantes, traditionnellement exploitée en Afrique de l'Ouest pour ses multiples vertus. Le genre Dioscorea comporte, de par le monde, plusieurs centaines d'espèces d'ignames sauvages dont l'identification n'est pas toujours aisée en raison de descriptions incomplètes et des nombreuses synonymies. Or, à des degrés divers, les espèces sauvages ont joué et jouent un rôle fondamental dans l'évolution des formes cultivées. Leur identification est donc une nécessité en vue de, leur préservation et de leur utilisation judicieuse. Ce manuel propose une reconnaissance des espèces in situ et, compte tenu de la grande diversité des ignames, amorce une réflexion sur la conservation et l'évaluation de leurs ressources génétiques. The so-called minor plants (that is to say those of no importance to the world economy) play a fundamental role in Africa. They contribute to self-sufficiency in food supplies by providing scope for crop diversification. Yam is one of these plants and is grown traditionally in West Africa for its many virtues. The genus Dioscorea contains several hundred species of wild yams whose identification is not always easy because of incomplete descriptions and numerous synonyms. However, wild species have been and still are of prime importance for the development of cultivated varieties. They should therefore be identified for the purpose of conservation and judicious use. This handbook proposes identification of yams in situ and, in the light of their great diversity, discusses the conservation and appraisal of their genetic resources.
Download or read book Encyclopedia of Global Archaeology written by and published by Springer. This book was released on 2013-12-04 with total page 8015 pages. Available in PDF, EPUB and Kindle. Book excerpt: Archaeology – the study of human cultures through the analysis and interpretation of artefacts and material remains – continues to captivate and engage people on a local and global level. Internationally celebrated heritage sites such as the pyramids—both Egyptian and Mayan—Lascaux caves, and the statues of Easter Island provide insights into our ancestors and their actions and motivation. But there is much more to archaeology than famous sites. Ask any archaeologist about their job and they will touch on archaeological theory, chemistry, geology, history, classical studies, museum studies, ethical practice, and survey methods, along with the analysis and interpretation of artefacts and sites. Archaeology is a much broader subject than its public image and branches into many other fields in the social and physical sciences. This multi-volume work provides a comprehensive and systematic coverage of archaeology that is unprecedented, not only in terms of the use of multi-media, but also in terms of content. It encompasses the breadth of the subject along with key aspects that are tapped from other disciplines. It includes all time periods and regions of the world and all stages of human development. Mostly importantly, this encyclopedia includes the knowledge of leading scholars from around the world. The entries in this encyclopedia range from succinct summaries of specific sites and the scientific aspects of archaeological enquiry to detailed discussions of archaeological concepts, theories and methods, and from investigations into the social, ethical and political dimensions of archaeological practice to biographies of leading archaeologists from throughout the world. The different forms of archaeology are explored, along with the techniques used for each and the challenges, concerns and issues that face archaeologists today. The Encyclopedia of Global Archaeology has two outstanding innovations. The first is that scholars were able to submit entries in their own language. Over 300,000 words have been translated from French, Spanish, Portuguese, German, Italian, Japanese, Turkish and Russian. Many of these entries are by scholars who are publishing in English for the first time. This compendium is both a print reference and an online reference work. The encyclopedia’s second major innovation is that it harnesses the capabilities of an online environment, enhancing both the presentation and dissemination of information. Most particularly, the continuous updating allowed by an online environment should ensure that the Encyclopedia of Global Archaeology is a definitive reference work for archaeology and archaeologists.

Download or read book Yams written by Anthony Keith Thompson and published by CABI. This book was released on 2021-09-20 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dioscorea species, commonly known as yams, are tuberous plants that constitute a major staple food in many parts of Africa, South East Asia, Latin America and the South Pacific. Yams are cultivated in about 50 mainly tropical countries, and the world annual production of edible tubers is around 73 million tonnes. This book evaluates the current state of knowledge about yams, and how this knowledge affects practices in production, cultivation and postharvest technology. Dioscorea is a diverse genus in terms of its geographical origin, domestication, morphology, chemistry and breeding. Therefore, besides concentrating on the dozen or so species that are used as major food crops, the book examines species that have limited commercial or domestic value at present, but have the potential in future to contribute to the production and utilization of this crop.

Download or read book World Vegetables written by Vincent E. Rubatzky and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 860 pages. Available in PDF, EPUB and Kindle. Book excerpt: Completely revised and up-to-date, this wide-ranging, comprehensive treatise examines the many different aspects of vegetables from an international perspective. The diversity and depth of coverage of vegetables is largely due to the extensive background and experiences of the authors, Vincent Rubatzky and Mas Yamaguchi, as well as considerable input from colleagues and expert reviewers. This logically-organized text, filled with numerous illustrations, photographs, and tables, begins with an easy-to-read introduction to such topics as: the current role of vegetables as a world food crop, the origin and classification of vegetables, vegetables in human nutrition, and plant toxicants and folklore concerning vegetables. Background material on the basic principles for growing crops and production under adverse conditions are also featured in this section. Much of the material covered in the book focuses on the major and minor vegetables, their origin, taxonomy, botany, physiology, production and post harvest handling, and composition and use. In addition, current world production statistics are provided for many vegetable crops as well as listings of important diseases, insects, and other pests for many family groups. New features of this edition include: *Three new chapters covering mushrooms, aquatic vegetables, and herbs and spices *several appendix tables listing vegetables according to family, genus, species, nutritive value, and recommended storage conditions for many vegetables The introductory chapter offers an excellent background of the role of vegetables for the beginning and advanced students, both in the U.S. and worldwide. The chapters following provide extension professionals, professors, agricultural agencies, commercial growers, and processing and seed industry personnel with a better understanding of individual vegetable species.
