This paper describes how modern service providers have emerged in the African agricultural sector, a subject that has been vastly understudied. The paper looks at providers of modern rice mills, power tillers, combine harvesters, and production services at a highly productive rice irrigation scheme in Ghana. These service providers earn net profits that are greater than the profits they would likely achieve from simply expanding rice production without investing in respective machines, suggesting that higher returns primarily induce the emergence of these modern providers. Surpluses and experiences from their years of rice production are likely to have provided the primary finance and knowledge required for entry. The service providers emerged by exploiting both the economies of scale and the economies of scope, keeping rice production as the primary source of income, instead of specializing only in service provisions. Key policy implications are also discussed.

In this study, we contribute to such efforts to enhance the use of tractors in Africa by describing the key characteristics of markets for tractors in Nigeria. Nigeria is among a set of countries in Africa that has both low agricultural productivity and low agricultural mechanization growth (Malabo Montpellier Panel 2018). Current understanding of the tractor market in Nigeria mainly highlights only specific aspects of mechanization issues or only delves into the application of specific emergent mechanization technologies. Consequently, many stakeholders do not have sufficient understanding of how tractor markets in Nigeria are organized both in vertical and in geographic terms.

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.

This paper provides a helpful framing to understand both why and how policy attention and investments should be channeled through agriculture and agrifood systems as key vehicles for achieving the Sustainable Development Goals (SDGs). It illustrates the ways in which agriculture, particularly within the context of food value chains, is uniquely positioned to holistically address the social, economic, and environmental dimensions of sustainable development because of its existing reach and future potential. In this paper’s examination of the multiplicity of entry points the sector offers for fostering inclusive and sustainable economic growth, reversing harmful environmental trends, and enhancing the resilience of the poorest and most vulnerable populations, it traces some of the most potent pathways for agricultural policies and interventions to accelerate development outcomes across all country contexts.

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.

A growing number of governments, donor agencies, and development organizations are committed to supporting nutrition-sensitive agriculture (NSA) to achieve their development goals. Although consensus exists on pathways through which agriculture may influence nutrition-related outcomes, empirical evidence on agriculture’s contribution to nutrition and how it can be enhanced is still weak. This paper reviews recent empirical evidence (since 2014), including findings from impact evaluations of a variety of NSA programs using experimental designs as well as observational studies that document linkages between agriculture, women’s empowerment, and nutrition. It summarizes existing knowledge regarding not only impacts but also pathways, mechanisms, and contextual factors that affect where and how agriculture may improve nutrition outcomes. The paper concludes with reflections on implications for agricultural programs, policies, and investments, and highlights future research priorities.

This paper examines the fertilizer subsidy program in Nepal from two different angles, both important for policy makers in the country. First, it analyzes who is benefiting from the program, and second, it examines how farmers rank the importance of public spending on fertilizer subsidies compared with other potential public investments. Whereas the former question is important for judging whether the program is meeting its objectives, the latter is essential to understanding the scope for reform, in particular the extent to which we could expect citizens to resist reforms to the subsidy program. We draw on these analyses as well as on examples from other countries to make policy recommendations to improve program implementation.

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

Independent, scientifically based, integrated, policy-relevant analysis of current and emerging energy issues for specialists and policymakers in academia, industry, government.
