Root and tuber crops are important to agriculture, food security and income for 2.2 billion people in developing countries. These species produce large quantities of dietary energy and have stable yields under difficult environmental conditions. This second edition of Tropical Root and Tuber Crops is an authoritative treatment of four important root and tuber crops: cassava. sweet potato, yams, and aroids.

The volume analyses how to make Science, Technology and Innovation (STI) Policies relevant for inclusive growth strategies in Africa.The base for a transformative STI policy is to link the STI policies to Africa's economic transformation policies. In a first part the general issues of introducing effective STI policies are presented. In a second part country case studies highlight the new approach. Cases such as Sudan and Nigeria are analysed, as these two countries have a long history of STI development; because of different history, size and structure they need to move in different directions towards a coherent STI policy for inclusive growth.

Basic approaches to maintaining the safety and quality of horticultural produce are the same, regardless of the market to which this produce is targeted. This bulletin reviews the factors which contribute to quality and safety deterioration of horticultural produce, and describes approaches to assuring the maintenance of quality and safety throughout the post-harvest chain. Specific examples are given to illustrate the economic implications of investing in and applying proper post-harvest technologies. Criteria for the assessment of post-harvest needs, the selection of post-harvest technologies appropriate to the situation and context, and for extending appropriate levels of post-harvest information are also discussed.

Producers spend a great deal of money, natural resources (especially water and soil), labor, and time every year in order to feed the world’s population. However, almost one-third of the products produced as a result of all these efforts are lost before reaching consumers due to postharvest losses, which threaten both the food supply and agricultural sustainability. For this reason, it is extremely important to prevent postharvest losses of fruits and vegetables. In this context, this book provides general and new information about the physiology of postharvest losses and the latest technological developments in postharvest systems. Each chapter provides up-to-date information about the postharvest physiology and technology of fruits and vegetables for students, teachers, professors, scientists, farmers, food packers and sellers, and entrepreneurs engaged in the fresh food preservation industry.

This open access book describes recent innovations in food systems based on root, tuber and banana crops in developing countries. These innovations respond to many of the challenges facing these vital crops, linked to their vegetative seed and bulky and perishable produce. The innovations create value, food, jobs and new sources of income while improving the wellbeing and quality of life of their users. Women are often key players in the production, processing and marketing of roots, tubers and bananas, so successful innovation needs to consider gender. These crops and their value chains have long been neglected by research and development, hence this book contributes to filling in the gap. The book features many outcomes of the CGIAR Research Program in Roots, Tubers and Banana (RTB), which operated from 2012-21, encompassing many tropical countries, academic and industry partners, multiple crops, and major initiatives. It describes the successful innovation model developed by RTB that brings together diverse partners and organizations, to create value for the end users and to generate positive economic and social outcomes. RTB has accelerated the scaling of innovations to reach many end users cost effectively. Though most of the book's examples and insights are from Africa, they can be applied worldwide. The book will be useful for decision makers designing policies to scale up agricultural solutions, for researchers and extension specialists seeking practical ideas, and for scholars of innovation.
