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.

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.

Brazil has emerged as a significant financial and industrial power in recent times. Brazil is poised to become a significant player in the field of biotechnology, internationally, by taking advantage of circumstances not available in other countries, particularly its native biodiversity. This will, in turn, have an effect on commercial and entrepreneurial opportunities in the region. Topics covered in this text include adjustments that must be made in the regulatory framework to assure the success of business investment. This investment is crucial for training R&D scientists and developing new technologies. The book also covers a debate on transgenic plants which had political ramifications in the region and slowed the adoption rate of genetically modified organisms by almost a decade. The opportunities for commercialization of recombinant DNA technologies in the country are also presented. Opportunities and Limitations For Biotechnology Innovation In Brazil presents a concise overview of the biotechnology industry in Brazil and will be of great interest to a wide range of readers including researchers, biotechnology graduates, as well as both local and international investors.

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.

This critical text is a timely ethnography of how global powers, local resistance, and capital flows are shaping contemporary African foodways. Ghana was one of the first countries targeted by a group of US donors and agribusiness corporations that funded an ambitious plan to develop genetically modified (GM) crops for African farmers. The collective believed that GM crops would help farmers increase their yields and help spark a “new” Green Revolution on the continent. Soon after the project began in Ghana, a nationwide food sovereignty movement emerged in opposition to GM crops. Today, in spite of impressive efforts and investments by proponents, only two GM crops remain in the pipeline. Why, after years of preparation, millions of dollars of funding, and multiple policy reforms, did these megaprojects effectively come to a halt? One of the first ethnographies to take on the question of GM crops in the African context, We Are Not Starving: The Struggle for Food Sovereignty in Ghana blends archival analysis, interviews, and participant observation with Ghanaian scientists, farmers, activists, and officials. Ultimately the text aims to illuminate why GM crops have animated the country and to highlight how their introduction has opened an opportunity to air grievances about the systematic de-valuing and exploitation of African land, labor, and knowledge that have been centuries in the making.

Research paper on obstacles to rural women's access to agricultural credit and technology in developing countries - covers constraints such as the dual economy, sexual division of labour, insufficient knowhow and ineffective demand by women, programme planning focus of governments, bilateral aid and international organizations, choice of technology not adapted to women's needs, their participation in credit systems, etc., and includes technology and credit policy recommendations.

Many people believe that organic agriculture is a solution for various problems related to food production. Organic agriculture is supposed to produce healthier products, does not pollute the environment, improves the fertility of soils, saves fossil fuels and enables high biodiversity. This book has been written to provide scientifically based information on organic agriculture such as crop yields, food safety, nutrient use efficiency, leaching, long-term sustainability, greenhouse gas emissions and energy aspects. A number of scientists working with questions related to organic agriculture were invited to present the most recent research and to address critical issues. An unbiased selection of literature, facts rather than standpoints, and scientifically-based examinations instead of wishful thinking will help the reader be aware of difficulties involved with organic agriculture. Organic agriculture, which originates from philosophies of nature, has often outlined key goals to reach long-term sustainability but practical solutions are lacking. The central tasks of agriculture - to produce sufficient food of high quality without harmful effects on the environment - seem to be difficult to achieve through exclusively applying organic principles ruling out many valuable possibilities and solutions.

As development donors invest hundreds of millions of dollars into improved crops designed to alleviate poverty and hunger, Africa has emerged as the final frontier in the global debate over agricultural biotechnology. The first data-driven assessment of the ecological, social, and political factors that shape our understanding of genetic modification, Africa's Gene Revolution surveys twenty years of efforts to use genomics-based breeding to enhance yields and livelihoods for African farmers. Matthew Schnurr considers the full range of biotechnologies currently in commercial use and those in development – including hybrids, marker-assisted breeding, tissue culture, and genetic engineering. Drawing on interviews with biotechnology experts alongside research conducted with more than two hundred farmers across eastern, western, and southern Africa, Schnurr reveals a profound incongruity between the optimistic rhetoric that accompanies genetic modification technology and the realities of the smallholder farmers who are its intended beneficiaries. Through the lens of political ecology, this book demonstrates that the current emphasis on improved seeds discounts the geographic, social, ecological, and economic contexts in which the producers of these crops operate. Bringing the voices of farmers to the foreground of this polarizing debate, Africa's Gene Revolution contends that meaningful change will come from a reconfiguration not only of the plant's genome, but of the entire agricultural system.

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.

The history of food is one of the fastest growing areas of historical investigation, incorporating methods and theories from cultural, social, and women’s history while forging a unique perspective on the past. The Routledge History of Food takes a global approach to this topic, focusing on the period from 1500 to the present day. Arranged chronologically, this title contains 17 originally commissioned chapters by experts in food history or related topics. Each chapter focuses on a particular theme, idea or issue in the history of food. The case studies discussed in these essays illuminate the more general trends of the period, providing the reader with insight into the large-scale and dramatic changes in food history through an understanding of how these developments sprang from a specific geographic and historical context. Examining the history of economic, technological, and cultural interactions between cultures and charting the corresponding developments in food history, The Routledge History of Food challenges readers' assumptions about what and how people have eaten, bringing fresh perspectives to well-known historical developments. It is the perfect guide for all students of social and cultural history.
