Limits to green revolution in rice in Africa by Ragasa, Catherine,Chapoto, Anthony Pdf
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.
An African Green Revolution by Keijiro Otsuka,Donald F. Larson Pdf
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.
Africa’s Green Revolution by William G. Moseley,Matthew A. Schnurr,Rachel Bezner-Kerr Pdf
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.
In Pursuit of an African Green Revolution by Keijiro Otsuka,Donald F. Larson Pdf
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.
Rice Green Revolution in Sub-Saharan Africa by Keijiro Otsuka,Yukichi Mano,Kazushi Takahashi Pdf
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.
Innovations as Key to the Green Revolution in Africa by Andre Bationo,Boaz Waswa,Jeremiah M. Okeyo,Fredah Maina,Job Maguta Kihara Pdf
Africa can achieve self sufficiency in food production through adoption of innovations in the agriculture sector. Numerous soil fertility and crop production technologies have been generated through research, however, wide adoption has been low. African farmers need better technologies, more sustainable practices, and fertilizers to improve and sustain their crop productivity and to prevent further degradation of agricultural lands. The agricultural sector also needs to be supported by functional institutions and policies that will be able to respond to emerging challenges of globalization and climate change.
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.

Lost Crops of Africa by National Research Council,Policy and Global Affairs,Office of International Affairs,Board on Science and Technology for International Development Pdf
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.

Africa's Gene Revolution by Matthew A. Schnurr Pdf
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.
Opportunities And Limitations For Biotechnology Innovation in Brazil by Luiz A.B. de Castro,Carlos A.L. Neri,Carlos Bloch Junior,Manoel O.de Moraes Filho Pdf
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.

The Green Revolution in the Global South by R. Douglas Hurt Pdf
A synthesis of the agricultural history of the Green Revolution The Green Revolution was devised to increase agricultural production worldwide, particularly in the developing world. Agriculturalists employed anhydrous ammonia and other fertilizing agents, mechanical tilling, hybridized seeds, pesticides, herbicides, and a multitude of other techniques to increase yields and feed a mushrooming human population that would otherwise suffer starvation as the world’s food supply dwindled. In The Green Revolution in the Global South: Science, Politics, and Unintended Consequences, R. Douglas Hurt demonstrates that the Green Revolution did not turn out as neatly as scientists predicted. When its methods and products were imported to places like Indonesia and Nigeria, or even replicated indigenously, the result was a tumultuous impact on a society’s functioning. A range of factors—including cultural practices, ethnic and religious barriers, cost and availability of new technologies, climate, rainfall and aridity, soil quality, the scale of landholdings, political policies and opportunism, the rise of industrial farms, civil unrest, indigenous diseases, and corruption—entered into the Green Revolution calculus, producing a series of unintended consequences that varied from place to place. As the Green Revolution played out over time, these consequences rippled throughout societies, affecting environments, economies, political structures, and countless human lives. Analyzing change over time, almost decade by decade, Hurt shows that the Green Revolution was driven by the state as well as science. Rather than acknowledge the vast problems with the Green Revolution or explore other models, Hurt argues, scientists and political leaders doubled down and repeated the same missteps in the name of humanity and food security. In tracing the permutations of modern science’s impact on international agricultural systems, Hurt documents how, beyond increasing yields, the Green Revolution affected social orders, politics, and lifestyles in every place its methods were applied—usually far more than once.
