Download or read book Production Technology of Underutilized Vegetable Crops written by Savita and published by Springer Nature. This book was released on 2023-04-20 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume discusses the nutraceutical importance, production technologies, management and cultivation practices of underutilized vegetables, which can be described as those vegetable crops which are neither grown commercially on a large scale nor traded widely. While much of the crops addressed in the book are cultivated, traded and consumed at the local level, there are over 60 species of minor vegetables with high growth and yield potentials that are not cultivated to a large extent for greater populations. This work highlights the production technologies needed to grow these vegetables on a larger scale and under various adverse soil and climatic conditions, and their nutritional and medical benefits to assist with food security, health and poverty alleviation in rural areas. Production of underutilized vegetables is low, due to the unavailability of planting material, lack of awareness about the nutritional and medicinal importance among the farmers and inadequate information on the production techniques of these crops. In this context, there is an urgent need to take up a program on genetic resources exploration, management, utilization, and improvement of underutilized vegetable crops to ensure food and nutritional security. Readers will learn about these technologies and practices, while also learning about the unique properties and benefits of these underutilized vegetables. The book will be useful for academicians and researchers focusing on vegetable production and breeding, as well as farmers and sustainability scientists looking for underexplored sources of nutrition to benefit large rural populations.

Download or read book Deep Roots written by Edda L. Fields-Black and published by Indiana University Press. This book was released on 2008-10-20 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mangrove rice farming on West Africa's Rice Coast was the mirror image of tidewater rice plantations worked by enslaved Africans in 18th-century South Carolina and Georgia. This book reconstructs the development of rice-growing technology among the Baga and Nalu of coastal Guinea, beginning more than a millennium before the transatlantic slave trade. It reveals a picture of dynamic pre-colonial coastal societies, quite unlike the static, homogenous pre-modern Africa of previous scholarship. From its examination of inheritance, innovation, and borrowing, Deep Roots fashions a theory of cultural change that encompasses the diversity of communities, cultures, and forms of expression in Africa and the African diaspora.
Download or read book Encyclopedia of Cultivated Plants 3 volumes written by Christopher Cumo and published by Bloomsbury Publishing USA. This book was released on 2013-04-25 with total page 1223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Readers of this expansive, three-volume encyclopedia will gain scientific, sociological, and demographic insight into the complex relationship between plants and humans across history. Comprising three volumes and approximately half a million words, this work is likely the most comprehensive reference of its kind, providing detailed information not only about specific plants and food crops such as barley, corn, potato, rice, and wheat, but also interdisciplinary content that draws on the natural sciences, social sciences, and humanities. The entries underscore the fascination that humans have long held for plants, identifies the myriad reasons why much of life on earth would be impossible without plants, and points out the intertwined relationship of plants and humans—and how delicate this balance can be. While the majority of the content is dedicated to the food plants that are essential to human existence, material on ornamentals, fiber crops, pharmacological plants, and carnivorous plants is also included.
Download or read book Nuaulu Settlement and Ecology written by Roy F. Ellen and published by BRILL. This book was released on 2012-12-11 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the pattern of settlement and ecology of the Nuaulu, a group of sedentary swidden cultivators and hunters of southcentral Seram (Eastern Indonesia). It has three inter-related aims: to describe and account for nuaulu settlement; to outline and exemplify a suitable method of assessing the fine inter-action of cultural and ecological variables in small scale communities; and to explore the usefulness of a generative form of analysis in this respect. The fieldwork among the Nuaulu was undertaken between December 1969 and May 1971, and again for three months in 1973. After some basic introductory information, the analysis proceeds by first examining the residential component of the settlement patterns in terms of the processes which determine its location, form and composition. Next, the role of non-domesticated resources in local ecology and the processes of settlement generation in the domesticated component of the Nuaulu environment is investigated. In the final section the general theoretical and methodological issues raised in the introduction are examined in the light of the preceeding analysis.
Download or read book Archaeology in Environment and Technology written by David Frankel and published by Routledge. This book was released on 2013-05-02 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environments, landscapes, and ecological systems are often seen as fundamental by archaeologists, but how they relate to society is understood in very different ways. The chapters in this book take environment, culture, and technology together. All have been the focus of much attention; often one or other has been seen as the starting point for analysis, but this volume argues that it is the study of the inter-relationships between these three factors that offers a way forward. The contributions to this book pick up different strands within the tangled web of intersections between environment, technology, and society, providing a series of case studies which explore facets of this common theme in different settings and circumstances and from different perspectives. As well as addressing themes of theoretical and methodological interest, these case studies draw on primary research dealing with time periods from the late Pleistocene glacial maximum to the very recent past, and involve societies of very different types. Running through all the contributions, however, is a concern with the archaeological record and the ways in which scales of observation and availability of evidence affect the development of questions and explanations. The diversity of the chapters in this volume demonstrates the inherent weakness in any attempt to prioritise environment, technology, or society. These three factors are all embedded in any human activity, as change in one will result in change in the others: social and technical changes alter relations with the environment–and indeed the environment itself—and as environmental change drives changes in society and technology. As this book shows, it is possible to consider the relationship between the three factors from different perspectives, but any attempt to consider one or even two in isolation will mean that valuable insights will be missed.
Download or read book Archaeology and Language II written by Roger Blench and published by Routledge. This book was released on 2003-09-02 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using language to date the origin and spread of food production, Archaeology and Language II represents groundbreaking work in synthesizing two disciplines that are now seen as interlinked: linguistics and archaeology. This volume is the second part of a three-part survey of innovative results emerging from their combination. Archaeology and historical linguistics have largely pursued separate tracks until recently, although their goals can be very similar. While there is a new awareness that these disciplines can be used to complement one another, both rigorous methodological awareness and detailed case-studies are still lacking in the literature. This three-part survey is the first study to address this. Archaeology and Language II examines in some detail how archaeological data can be interpreted through linguistic hypotheses. This collection demonstrates the possibility that, where archaeological sequences are reasonably well-known, they might be tied into evidence of language diversification and thus produce absolute chronologies. Where there is evidence for migrations and expansions these can be explored through both disciplines to produce a richer interpretation of prehistory. An important part of this is the origin and spread of food production which can be modelled through the spread of both plants and words for them. Archaeology and Language II will be of interest to researchers in linguistics, archaeologists and anthropologists.

Download or read book Food Crop Production by Smallholder Farmers in Southern Africa written by Ambayeba Muimba-Kankolongo and published by Academic Press. This book was released on 2018-02-07 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food Crop Production by Smallholder Farmers in Southern Africa: Challenges and Opportunities for Improvement evaluates traditional cultivation practices used by smallholder farmers, providing a synthesis of the latest information on increasing crop yield through adoption of research innovations. The book catalogs smallholder cultivation practices and recommends innovative strategies for improving the agriculture sector including: management practices that reduce net carbon emissions; technologies that improve soil structures and conserve the natural resources base; means of empowering female resources along value chains; and government commitment to adopt policies that enhance agriculture productivity by encouraging farmers to use environmentally sound cultivation technologies. Traditional farming techniques often produce negative impacts on the environment and ecosystem resulting in outbreaks of diseases and pests. In addition to the region's recurrent droughts, these outbreaks of numerous diseases and pests, weeds and other invasive plants put thousands at risk of poverty and hunger, as well as malnutrition. This book presents enhanced agricultural production technologies for ensuring adequate food production, safety and nutritional quality for the population of Southern Africa and forms the basis for an increased SADC regional effort in food production through which financial and trade institutions can improve stakeholder capacities, encourage micro-enterprise development and enhance employment and regional trade. - Provides a critical synthesis of data and information for increasing crop yield through adoption of research innovations - Evaluates traditional and scientific interventions that address food security issues of the poor farmers in the region - Presents agro-ecologies of countries in the region and how they relate to various cultivation practices - Catalogs smallholder cultivation practices and recommends innovative strategies for improving the agriculture sector
Download or read book Maize and Grace written by James C. McCann and published by Harvard University Press. This book was released on 2007-09-15 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sometime around 1500 AD, an African farmer planted a maize seed imported from the New World. That act set in motion the remarkable saga of one of the world’s most influential crops—one that would transform the future of Africa and of the Atlantic world. Africa’s experience with maize is distinctive but also instructive from a global perspective: experts predict that by 2020 maize will become the world’s most cultivated crop. James C. McCann moves easily from the village level to the continental scale, from the medieval to the modern, as he explains the science of maize production and explores how the crop has imprinted itself on Africa’s agrarian and urban landscapes. Today, maize accounts for more than half the calories people consume in many African countries. During the twentieth century, a tidal wave of maize engulfed the continent, and supplanted Africa’s own historical grain crops—sorghum, millet, and rice. In the metamorphosis of maize from an exotic visitor into a quintessentially African crop, in its transformation from vegetable to grain, and from curiosity to staple, lies a revealing story of cultural adaptation. As it unfolds, we see how this sixteenth-century stranger has become indispensable to Africa’s fields, storehouses, and diets, and has embedded itself in Africa’s political, economic, and social relations. The recent spread of maize has been alarmingly fast, with implications largely overlooked by the media and policymakers. McCann’s compelling history offers insight into the profound influence of a single crop on African culture, health, technological innovation, and the future of the world’s food supply.
Download or read book The Archaeology of Africa written by Bassey Andah and published by Routledge. This book was released on 2014-05-22 with total page 896 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa has a vibrant past. It emerges from this book as the proud possessor of a vast and highly complicated interweaving of peoples and cultures, practising an enormous diversity of economic and social strategies in an 2xtraordinary range of environmental situations. At long last the archaeology of Africa has revealed enough of Africa's unwritten past to confound preconceptions about this continent and to upset the picture inferred from historic written records. Without an understanding of its past complexities, it is impossible to grasp Africa's present, let alone its future.
