This book was released on 2016-09-29 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines closely the constraints in productivity improvements and evaluates available rice technologies looking at the heterogeneity of irrigated and rainfed ecologies in 10 regions in Ghana. Employing yield response models, profitability analysis, and adoption models, results show various practices contribute to yield improvements in irrigated and rainfed systems including chemical fertilizer use, use of certified seed of improved varieties, transplanting, bunding, leveling, use of a sawah system, seed priming, and row planting. Evidence also shows that extension services on rice production are limited and that intensifying extension services can contribute to increases in rice yield.
Download or read book Africa s Green Revolution written by William G. Moseley and published by Routledge. This book was released on 2017-10-02 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume examines the dominant neoliberal agenda for agricultural development and hunger alleviation in Africa. The text reviews the history of African agricultural and food security policy in the post-colonial period, across a range of geographical contexts, in order to contextualise the productionist approach embedded in the much heralded New Green Revolution for Africa. This strategy, supported by a range of international agencies, promotes the use of hybrid seeds, fertilisers, and pesticides to boost crop production. This approach is underpinned by a new and unprecedented level of public–private partnerships as donors actively work to promote the private sector and build links between African farmers, input suppliers, agro-dealers, agro-processors, and retailers. On the consumer end, increased supermarket penetration into poorer neighbourhoods is proffered as a solution to urban food insecurity. The chapters in this volume complicate understandings of this new approach and raise serious questions about its effectiveness as a strategy for increasing food production and alleviating poverty across the continent. This book is based on a special issue of African Geographical Review.
Download or read book In Pursuit of an African Green Revolution written by Keijiro Otsuka and published by Springer. This book was released on 2015-11-24 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores recent experiences in the effort to bring about a Green Revolution in Sub-Saharan Africa (SSA). The chapters focus on rice and maize, which are promising and strategic smallholder crops. Significantly, we find that an African Rice Revolution has already begun in many irrigated areas, using Asian-type modern varieties, chemical fertilizer, and improved management practices. Further, we find that the same technological package significantly increases the productivity and profitability of rice farming in rainfed areas as well. We also find evidence that that management training, when done well, can boost productivity on smallholder farms. This suggests that African governments can accelerate the pace of Africa’s Rice Revolution by strengthening extension capacity. The story for maize is wholly different, where most farmers use local varieties, apply little chemical fertilizer, and obtain very low yields. However, in the highly populated highlands of Kenya, a number of farmers have adopted high-yielding hybrid maize varieties and chemical fertilizer, as was the case in the Asian Green Revolution, apply manure produced by stall-fed cows, as was the case during the British Agricultural Revolution, and keep improved cows or cross-breeds from European cows and local stock, as was the case of the Indian White Revolution. We conclude that while rice in Africa has benefited from an Asian Green Revolution strategy that emphasizes modern seeds, inputs, and focused knowledge transfers, the success of Africa’s Maize Revolution will require a different system approach based on hybrid maize, chemical and organic fertilizers, and stall-fed cross-bred cows.
Download or read book Lost Crops of Africa written by National Research Council and published by National Academies Press. This book was released on 1996-02-14 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Rice Green Revolution in Sub Saharan Africa written by Keijiro Otsuka and published by Springer Nature. This book was released on 2023-03-01 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book seeks effective strategy to realize a rice Green Revolution in sub-Saharan Africa based on more than ten years of research team’s inquiries into determinants and consequences of new technology adoption in rice farming in seven countries in this region. Rigorous statistical analyses are carried out by using valuable household data of rice farmers. The book is actually sequel to the two earlier books on the same subject published by Springer and edited by K. Otsuka and D.F. Larson, An African Green Revolution published in 2013 and In Pursuit of an African Green Revolution in 2016. The main message of the first book was that rice is the most promising cereal crop in SSA because of the high transferability of Asian rice technology, whereas that of the second book was that rice cultivation training programs are effective in significantly increasing rice yield in SSA. This third book has wider coverage in terms of topics, study periods, and study sites. It continues to show the significant impacts of rice cultivation training on productivity and newly demonstrates the high sustainability of the productivity impact of the training and the existence of spillover effects from trainees to other farmers by using panel data. We newly assess the important role of mechanization in intensification of rice farming, high returns to large-scale irrigation schemes, and the critical role of rice millers in improving the quality of milled rice. Based on these studies, this book provides clear pathways toward full-fledged Green Revolution in rice farming in sub-Saharan Africa.
Download or read book An African Green Revolution written by Keijiro Otsuka and published by Springer Science & Business Media. This book was released on 2012-12-22 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores the usefulness of the Asian model of agricultural development for Africa, where, even before the recent world food crisis, half the population lived on less than on dollar a day, and a staggering one in three people and one third of all children were undernourished. Africa has abundant natural resources; agriculture provides most of its jobs, a third of national income and a larger portion of total export earnings. However the levels of land and labor productivity rank among the worst in the world. The book explains Africa’s productivity gap and proposes ways to close it, by examining recent experience in Africa and by drawing on lessons from Asia.
Download or read book An evolving paradigm of agricultural mechanization development How much can Africa learn from Asia written by Diao, Xinshen, ed. and published by Intl Food Policy Res Inst. This book was released on 2020-12-07 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural mechanization in Africa south of the Sahara — especially for small farms and businesses — requires a new paradigm to meet the needs of the continent’s evolving farming systems. Can Asia, with its recent success in adopting mechanization, offer a model for Africa? An Evolving Paradigm of Agricultural Mechanization Development analyzes the experiences of eight Asian and five African countries. The authors explore crucial government roles in boosting and supporting mechanization, from import policies to promotion policies to public good policies. Potential approaches presented to facilitating mechanization in Africa include prioritizing market-led hiring services, eliminating distortions, and developing appropriate technologies for the African context. The role of agricultural mechanization within overall agricultural and rural transformation strategies in Africa is also discussed. The book’s recommendations and insights should be useful to national policymakers and the development community, who can adapt this knowledge to local contexts and use it as a foundation for further research.

Available in PDF, EPUB and Kindle. Book excerpt: In The Nigerian Rice Economy the authors assess three options for reducing this dependency - tariffs and other trade policies; increasing domestic rice production; and improving post-harvest rice processing and marketing - and identify improved production and post-harvest activities as the most promising. These options however, will require substantially increased public investments in a variety of areas, including research and development, basic infrastructure (for example, irrigation, feeder roads, and electricity), and rice milling technologies.
Download or read book Securing the Harvest written by Joseph DeVries and published by CABI. This book was released on 2001 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improved food security, led by increased productivity among Africa's many small-scale farmers, has been the aim of significant national and international effort in recent decades. It has proved to be one of the most critical challenges facing humankind. This book grew out of a two-year exploration conducted by the food security theme of The Rockefeller Foundation focusing on the potential for crop genetic improvement to contribute to food security among rural populations in Africa. It provides a critical assessment of the ways in which recent breakthroughs in biotechnology, participatory plant breeding, and seed systems can be broadly employed in developing and delivering more productive crop varieties in Africa's diverse agricultural environments. It also presents an analysis of current plant breeding and biotechnology strategies for the key crops in Africa including: maize, sorghum, cowpea, rice, and cassava. The book will appeal to plant breeders, biotechnologists, and seed distributors as well as policy-makers in the area of agricultural development.
Download or read book The Rice Crisis written by David Dawe and published by Routledge. This book was released on 2012-07-26 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent escalation of world food prices – particularly for cereals - prompted mass public indignation and demonstrations in many countries, from the price of tortilla flour in Mexico to that of rice in the Philippines and pasta in Italy. The crisis has important implications for future government trade and food security policies, as countries re-evaluate their reliance on potentially more volatile world markets to augment domestic supplies of staple foods. This book examines how government policies caused and responded to soaring world prices in the particular case of rice, which is the world's most important source of calories for the poor. Comparable case studies of policy reactions in different countries, principally across Asia, but also including the USA, provide the understanding necessary to evaluate the impact of trade policy on the food security of poor farmers and consumers. They also provide important insights into the concerns of developing countries that are relevant for future international trade negotiations in key agricultural commodities. As a result, more appropriate policies can be put in place to ensure more stable food supplies in the future. Published with the Food and Agriculture (FAO) Organization of the United Nations
