Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates the potential of and constraints to a rice Green Revolution in Sub-Saharan Africa's large-scale irrigation schemes, using data from Uganda, Mozambique, Burkina Faso, Mali, Niger, and Senegal. The authors find that adequate irrigation, chemical fertilizer, and labor inputs are the key to high productivity. Chemical fertilizer is expensive in Uganda and Mozambique and is barely used. This is aggravated when water access is limited because of the complementarities between fertilizer and irrigation. Meanwhile, in the schemes located in four countries in West Africa's Sahel region, where water access is generally good and institutional support for chemical fertilizer exists, rice farmers achieve attractive yields. Some countries' wage rate is high and thus mechanization could be one solution for this constraint. Improvement of credit access also facilitates the purchase of expensive fertilizer or the employment of hired labor.

Book Synopsis Rice Green Revolution in Sub-Saharan Africa by : Keijiro Otsuka
Download or read book Rice Green Revolution in Sub-Saharan Africa written by Keijiro Otsuka. This book was released on 2023-03-01. 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.

Book Synopsis In Pursuit of an African Green Revolution by : Keijiro Otsuka
Download or read book In Pursuit of an African Green Revolution written by Keijiro Otsuka. This book was released on 2015-11-24. 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.
