An autobiographical, historical account of the author’s agricultural and rural development experiences.Includes analyses of historical and socio-political contexts of different countries and institutions.The text is in a relaxed, not strictly academic, style which facilitates easy reading. Tales from an Itinerant Agronomist covers a lifelong dedication to systems thinking and learning in agriculture and rural development. It follows the author’s own experiences, based at Universities and within International Aid programmes, developing farm and rural livelihood systems for small scale farming families. Covering extended time spent at educational and research institutions over the last 60 years; including Trinidad, Tanzania, Botswana, Sudan, Syria, Nepal and Namibia, and short periods in many other countries. The book looks at cross cutting themes including; the role of animal power in small farm systems, the performance of some agricultural and rural development educational institutions: Leeds University, UWI (Trinidad), University of East Anglia (Norwich,UK), WAU (Netherlands), SLU (Sweden) and a selected analysis of some trends and themes in agricultural research. Enriched by the inputs and experiences from many different farmers, colleagues and partnerships, Tales From an Itinerant Agronomist is suitable for readers with an interest in agriculture, farming, rural development, the environment and sustainability.

This framework presents ten interrelated principles/elements to guide Sustainable Agricultural Mechanization in Africa (SAMA). Further, it presents the technical issues to be considered under SAMA and the options to be analysed at the country and sub regional levels. The ten key elements required in a framework for SAMA are as follows: The analysis in the framework calls for a specific approach, involving learning from other parts of the world where significant transformation of the agricultural mechanization sector has already occurred within a three-to-four decade time frame, and developing policies and programmes to realize Africa’s aspirations of Zero Hunger by 2025. This approach entails the identification and prioritization of relevant and interrelated elements to help countries develop strategies and practical development plans that create synergies in line with their agricultural transformation plans. Given the unique characteristics of each country and the diverse needs of Africa due to the ecological heterogeneity and the wide range of farm sizes, the framework avoids being prescriptive.

Agricultural development research aims to generate new knowledge or to retrieve and apply existing forms of knowledge in ways that can be used to improve the welfare of people who are living in poverty or are otherwise excluded, for instance by gender-based discrimination. Its effective application therefore requires ongoing dialogue with and the strong engagement of men and women from poor marginal farming communities. This book discusses opportunities afforded by effective knowledge pathways linking researchers and farmers, underpinned by participatory research and gender analysis. It sets out practices and debates in gender-sensitive participatory research and technology development, concentrating on the empirical issues of implementation, impact assessment, and institutionalisation of approaches for the wider development and research community. It includes six full-length chapters and eight brief practical notes and is enhanced by an annotated resources list of relevant publications, organisations, and websites adding to the portfolio of approaches and tools discussed by the contributors. Most of the 33 contributing authors work in the specialised agencies that form part of the Consultative Group on International Agricultural Research (CGIAR). This book was published as a special issue of Development in Practice.

The last decade has seen some significant changes in international development and in the status of non-governmental organisations operating in the field. Not only has the number of NGOs virtually doubled; many of them have seen a considerable growth in their budgets, and have grown closer to governments and official aid agencies. NGOs are acknowledged by many to be more effective agents of development than governments or commercial interests ? even as a ?magic bullet? for development problems. Despite these positive trends, the real impact of the NGO sector is not well documented. This is partly because NGO performance-assessment and accountability methods are weak, and partly because NGOs are caught up increasingly in the world of official aid, which pushes them towards certain forms of evaluation at the expense of others. This unique book takes a hard and critical look at these issues, and describes how NGOs can, and must, improve the way they measure and account for their performance if they are to be truly effective.

Right now the number of people living on $2 a day or less is more than the entire population of the world in 1950. These 2.7 billion people are not just the world’s greatest challenge—they represent an extraordinary market opportunity. By learning how to serve them ethically and effectively, businesses can earn handsome profits while helping to solve one of the world’s most intractable problems. The key is what Paul Polak and Mal Warwick call Zero-Based Design: starting from scratch to create innovative products and services tailored for the very poor, armed with a thorough understanding of what they really want and need and driven by what they call “the ruthless pursuit of affordability.”Polak has been doing this work for years, and Warwick has extensive experience in both business and philanthropy. Together, they show how their design principles and vision can enable unapologetic capitalists to supply the very poor with clean drinking water, electricity, irrigation, housing, education, healthcare, and other necessities at a fraction of the usual cost and at profit margins attractive to investors. Promising governmental and philanthropic efforts to end poverty have not reached scale because they lack the incentives of the market to attract massive resources. This book opens an extraordinary opportunity for nimble entrepreneurs, investors, and corporate executives that will result not only in vibrant, growing businesses but also a better life for the world’s poorest people.

Vertisols, one of the eleven established soil orders, are clay soils with unusual and interesting properties. They cover more than 350 million hectares of land in the world and in tropical Africa alone there are over 100 million hectares. Because of their very small particle size and high surface area, these soils have higher physical and chemical reactivity than other soils. Their interaction with agrochemicals/industrial wastes, has been, increasingly, the subject of research especially in the last two decades. Vertisols create special problems when used for engineering purposes. This book is intended to provide comprehensive and state-of-the-art information about Vertisols worldwide. Special attention is given to the use and management of soils such as fertilizer use, crop selection, soil tillage, water restriction on land including irrigation, and soil erosion. A special chapter has been added to deal with geotechnical engineering of Vertisols. Vertisols have great potential for agricultural production but many, especially in the developing world, are underutilized due to a lack of understanding regarding their behaviour and management. This book is written by leading scientists worldwide. It is expected that this monograph will be of great use to soil scientists and agronomists, graduate and senior graduate students. Improvement of their management may solve the current food deficiency in the world.

The authors offer a broad-based development strategy to raise incomes through agricultural productivity growth and expanded rural employment. They present rich new information on the rural informal sector and on agriculture-industry interactions, and they analyze the impact of macroeconomic and social policies on the rural economy. Policy instruments aimed at bringing about broad-based development are carefully assessed - from fiscal policy to development of new seeds and farm implements.
