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.

Download or read book Human Health and Forests written by Carol J. Pierce Colfer and published by Earthscan. This book was released on 2012-05-04 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hundreds of millions of people live and work in forests across the world. One vital aspect of their lives, yet largely unexamined, is the challenge of protecting and enhancing the unique relationship between the health of forests and the health of people. This book, written for a broad audience, is the first comprehensive introduction to the issues surrounding the health of people living in and around forests, particularly in Asia, South America and Africa.Part I is a set of synthesis chapters, addressing policy, public health, environmental conservation and ecological perspectives on health and forests (including women and child health, medicinal plants and viral diseases such as Ebola, SARS and Nipah Encephalitis). Part II takes a multi-lens approach to lead the reader to a more concrete and holistic understanding. It features case studies from around the world that cover important issues such as the links between HIV/AIDS and the forest sector, and between diet and health. Part III looks at the specific challenges to health care delivery in forested areas, including remoteness and the integration of traditional medicine with modern health care. The generous use of boxes with specific examples adds layers of depth to the analyses. The book concludes with a synthesis designed for use by practitioners and policymakers to work with forest dwellers to improve their health and their ecosystems.This book is a vital addition to the knowledge base of all professionals, academics and students working on forests, natural resources management, health and development worldwide.Published with CIFOR and People and Plants International
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 Human Ecology written by Daniel G. Bates and published by Springer Science & Business Media. This book was released on 2010-03-29 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book arose from the need to develop accessible research-based case study material which addresses contemporary issues and problems in the rapidly evolving field of human ecology. Academic, political, and, indeed, public interest in the environmental sciences is on the rise. This is no doubt spurred by media coverage of climate change and global warming and attendant natural disasters such as unusual drought and flood conditions, toxic dust storms, pollution of air and water, and the like. But there is also a growing intellectual awareness of the social causes of anthropogenic environmental impacts, political vectors in determining conser- tion outcomes, and the role of local representations of ecological knowledge in resource management and sustainable yield production. This is reflected in the rapid increase of ecology courses being taught at leading universities in the fa- growing developing countries much as was the case a decade or two ago in Europe and North America. The research presented here is all taken from recent issues of Human Ecology: An Interdisciplinary Journal. Since the journal itself is a leading forum for cont- porary research, the articles we have selected represent a cross-section of work which brings the perspectives of human ecology to bear on current problems being faced around the world. The chapters are organized in such a way to facilitate the use of this volume either to teach a course or to introduce an informed reader to the field.

Download or read book Underutilised Crop Genomes written by Mark A. Chapman and published by Springer Nature. This book was released on 2022-11-03 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the uses for underutilized crops, presenting the state-of-the-art in terms of genome sequencing for over 30 crops, previously understudied and under-researched. In a changing climate and with significant pressure on the land, it is the ideal time to be discussing novel crops, with significant biotic and abiotic tolerances and/or rich nutrient profiles for consumers. Previously, the only species with sequenced genomes were high-profile internationally recognized crops, but in the current era genomes are being sequenced for dozens of crops, including those previously classified as underutilized, now being investigated. This book covers food crops, from fruits to tubers, and from grasses to legumes, as well as crops with non-food applications. Some of these crops have draft genomes, and others have polished genomes with extensive resequencing panels. Each chapter tells the story of an individual crop or crop group, written by experts, focusing on the genome data available, revealing more about crop domestication and genetic variation, and the current and future prospects given that this data is now becoming available. It also highlights how even small sequencing projects can provide draft genome sequences suitable for gene discovery, comparative genomics, and identification of molecular markers for understanding these crops further.

Download or read book Hunter Gatherers of the Congo Basin written by Barry S. Hewlett and published by Routledge. This book was released on 2017-07-12 with total page 699 pages. Available in PDF, EPUB and Kindle. Book excerpt: The forest foragers of the Congo Basin, known collectively as "Pygmies," are the largest and most diverse group of active hunter-gatherers remaining in the world. At least fifteen different ethno-linguistic groups exist in the Congo Basin with a total population of 250,000 to 350,000 individuals. Extensive knowledge about these groups has accumulated in the last forty years, but readers have been forced to piece together what is known from many sources. French, Japanese, American, and British researchers have conducted the majority of the research; each national research group has its own academic traditions, history, and publications. Here, leading academic authorities from diverse national traditions summarize recent research on forest hunter-gatherers. The volume explores the diversity and uniformity of Congo Basin hunter-gatherer life by providing detailed but accessible overviews of recent research. It represents the first book in over twenty-five years to provide a comprehensive and holistic overview of African forest hunter-gatherers. Chapters discuss the cultural variation in characteristic features of Congo Basin hunter-gatherer life, such as their yodeled polyphonic music, pronounced egalitarianism, multiple-child caregiving, and complex relations with neighboring farming groups. Other contributors address theoretical issues, such as why Pygmies are short, how tropical forest hunter-gatherers live without the carbohydrates they receive from neighboring farmers, and how hunter-gatherer children learn to share so extensively.
