Humanities & Social SciencesJune 2015Men, ideas and tanks
British military thought and armoured forces, 1903?39
by J. P. Harris
Men, ideas and tanks reviews the development of British military ideas on armoured forces from 1903 to 1939. Great Britain was the nation which first developed the tank, first used it in action and first gained dramatic results by employment. The British continued to be world leaders in the field of mechanised warfare until the early 1930s. J. P. Harris offers strikingly new interpretations of the early history of British armoured forces and explains why Great Britain had lost the lead by the outbreak of the Second World War. Available in paperback once more, this work will be of interest to all those concerned with British military history in the first half of the twentieth century, with the history of mechanised warfare and with the history of military thought. ;

Technology, Engineering & AgricultureDecember 2021Conservation Agriculture in Africa
Climate Smart Agricultural Development
by Saidi Mkomwa, Amir H Kassam
Tillage agriculture has led to wide-spread soil and ecosystem degradation globally, and more particularly in the developing regions. This is especially so in Africa where traditional agricultural practices have become unsustainable due to severe exploitation of natural resources with negative impacts on the environment. In addition, agriculture in Africa today faces major challenges including increased costs, climate change effects and a need for more sustainable production intensification methods. Conservation (no-tillage) agriculture has emerged as a major alternative sustainable agriculture practice in Africa and has spread to many African countries in the past decade as more development and research has enabled its extension and uptake. This landmark volume is based on the material presented at the Second Africa Congress on Conservation Agriculture which was held in Johannesburg, South Africa, 9-12 October 2018. The main theme of the Congress was: Making Climate Smart Agriculture Real in Africa with Conservation Agriculture: Supporting the Malabo Declaration and Agenda 2063. The Congress was aligned to mobilize stakeholders in all agriculture sectors to provide development support, impetus and direction to the vision and agenda for transforming African agriculture as set out by the Malabo Declaration and Agenda 2063. This book is aimed at all agricultural stakeholders in the public, private and civil sectors in Africa engaged in supporting the transformation of conventional tillage agriculture to Conservation Agriculture. This includes: researchers, academics, students, development stakeholders and policy makers as well as institutional libraries across the world.

April 2022Sustainable Agricultural Intensification
A Handbook for Practitioners in East and Southern Africa
by Mateete Bekunda, Jonathan Odhong, Irmgard Hoeschle-Zeledon
This book provides an insight into the background, lessons learned, and the methodology of facilitating the application of best-bet/best-fit agricultural technologies to smallholder farms in East and Southern Africa (ESA). All technologies highlighted within this book, except those on livestock feeding, were trialed and demonstrated in farmers' fields over an eight-year period [2012 - 2020] as part of the Feed the Future/USAID funded research-for-development Africa RISING ESA Project and supported by the CGIAR. The livestock feed technologies were compiled from Eastern Africa literature and included to offer a full set of technologies relevant for farmers in mixed farming systems. Topics covered include the introduction of resilient and nutrient-dense crops, better arrangement of crops in the field to amplify intercrop benefits, and the management of soils to improve soil fertility and minimize physical soil and nutrient loss. The publication also features technologies for postharvest loss reduction, livestock feeding, food processing, and in the later chapters, important expositions on how multiple technologies can be creatively integrated in a farming system and how key products of research can be taken to scale. In the first chapter and throughout the handbook, the importance of taking gender dynamics into account to ensure technologies produce equitable outcomes is emphasized. This book: provides evidence-based descriptions of sustainable agricultural intensification technologies that have been validated iteratively with smallholder farmers. a convenient, easy-to-read, and science-based 'how-to' guide for successful deployment of improved agricultural technologies that will ensure readers from development/scaling agencies save time and resources for research trials and instead focus on technology deployment. gives evidence of how building research and development partnerships can be a critical element for successful delivery and scaling up of agricultural technologies. The book is aimed primarily at development practitioners who seek new competences in taking new technologies to scale. However, the breadth of topics covered makes this book an essential resource for agricultural scientists as well as university and college students aspiring to apply systems thinking in future agricultural research and development work.

MedicineFebruary 2019Agriculture for Improved Nutrition
Seizing the Momentum
by Shenggen Fan, Sivan Yosef, Rajul Pandya-Lorch
Approximately 800 million people suffer from hunger, 2 billion from lack of micronutrients and more than 2 billion from excessive weight and obesity. There is renewed interest in reshaping agricultural and food systems at global, regional and national levels, so that poor and vulnerable people have access to nutritious sustenance. This book reviews research findings, results from on-the-ground programmes and interventions, and policy experiences from the past 5-10 years. It examines the direct and indirect effects of agriculture on nutrition, following the agricultural value chain to explore this complex relationship, from biodiversity and crop fortification, to programme evaluation, to the impact of agricultural policies on consumers' choices and actions. It explores the roles of various stakeholders along the chain including women and the private sector, and cross-cutting themes such as data and capacity building. Developing country experiences and the knowledge and action gaps that remain in truly integrating agriculture and nutrition aims and related practices are considered. Key features: -Considers the evidence base on the relationship between agriculture and nutrition. -Includes insights from internationally renowned researchers. -Presents data from real-world settings that is highly relevant to the challenges currently faced by developing countries. This book is ideal for policy-makers and students studying agriculture, international development and nutrition.

July 2024The Untold Stories of African Agriculture
Lessons from Ethiopia
by Tsedeke Abate
This landmark volume presents the results of a comprehensive and coherent in-depth assessment of Ethiopian agriculture and draws lessons from it to generate actionable recommendations that will inform policy decisions and priority setting for agricultural transformation across Africa. Policy makers in Africa are faced with the challenges of ensuring food and nutrition security and the economic wellbeing of their rapidly growing populations while at the same time maintaining the integrity of their natural resource base. Between 2000 and 2021, 74% of the growth in overall crop production on the continent was derived from increases in land area expansion, while increases in yield contributed only 26% of the growth. This unchecked expansion of land use puts the sustainability of the natural resource base under severe pressure. Even though some countries have made substantial increases in their farm productivity over the last two decades, the overall performance for Africa is far behind other regions. For the most part, in Africa, agriculture is not fulfilling its expected functions of food and nutrition security, increased export earnings, import substitution, and raw material supply for local industries. Attempts have been made to transform African agriculture over the years, but few countries have succeeded in achieving sustainable change. Using examples from Ethiopia this book identifies the major factors for success and the root causes of underperformance, and offers evidence-based recommendations for future decision making, policy change and the creation of growth. This book: · Draws on a unique set of case studies from Ethiopia described and told from a truly African perspective. · Emphasises to policy makers in Africa that development cannot be outsourced and there are no shortcuts; it is only through consistent effort and sustained support for their agricultural research and development that positive change can be brought about. · States that past agricultural development efforts by the international community have not properly included a strong African voice, and that therefore, all future academic research, policies and strategies dealing with the continent's agriculture and food security should be formulated by Africa's own leading thinkers and experts. · Is not a polemic; its arguments are knowledge and evidence based, building a compelling picture of how agricultural development can be sustained for the future.
