Book Description
A comprehensive guide that covers the banana’s full value chain – from production to consumption The banana is the world’s fourth major fruit crop. Offering a unique and in-depth overview of the fruit’s entire value chain, this important new handbook charts its progression from production through to harvest, postharvest, processing, and consumption. The most up-to-date data and best practices are drawn together to present guidelines on innovative storage, processing, and packaging technologies, while fresh approaches to quality management and the value-added utilization of banana byproducts are also explained. Additionally, the book examines the banana’s physiology, nutritional significance, and potential diseases and pests. The book also Edited by noted experts in the field of food science, this essential text: Provides a new examination of the world’s fourth major fruit crop Covers the fruit’s entire value chain Offers dedicated chapters on bioactive and phytochemical compounds found in bananas and the potential of processing byproducts Gives insight into bananas’ antioxidant content and other nutritional properties Identifies and explains present and possible effects of bioactive and phytochemical compounds Handbook of Banana Production, Postharvest Science, Processing Technology, and Nutrition offers the most far-reaching overview of the banana currently available. It will be of great benefit to food industry professionals specializing in fruit processing, packaging, and manufacturing banana-based products. The book is also an excellent resource for those studying or researching food technology, food science, food engineering, food packaging, applied nutrition, biotechnology, and more.

Book Description
Banana Xanthomonas wilt caused by Xanthomonas vascicola pv musacearum (Xvm) devastates banana in East and Central Africa causing total yield loss in diseased plants. Previous germplasm screening experiments has identified M. balbisiana, a wild banana type, as an important Xvm resistance source but with exact resistance mechanism still to be defined. This PhD study was therefore aimed to evaluate the possible mechanism. For the study, clean M. balbisiana plantlets were required that were obtained through a newly developed tissue culture process. In the absence of a suitable banana culture medium, the MS proliferation medium was, in a first step, modified by increasing concentrations of the antioxidants ascorbic acid and thiamine-HCl to 20 mg/l and 0.18 mg/l, respectively. In addition, culturing the explants in total darkness for the first 9 weeks after initiation improved plantlet proliferation. Modifications applied enabled production of up to 40 M. balbisiana plantlets per explant. In a further step, multiplication and migration of Xvm in M. balbisiana plantlets following injection was investigated and compared to susceptible banana EAHB cv Nakinyika . Treatment of the youngest open leaf with a bacterial suspension delayed symptom development in M. balbisiana and symptoms only appeared 10 weeks after inoculation. In addition, wilt incidence and severity were only 33% and 20%, respectively, with only the symptomatic leaves, inoculated and the immediate follower leaves, eventually dying. In addition, a general decline in the population of the bacterium in the plant occurred, though the bacterium initially migrated to the leaves that are immediate followers to the inoculated leaf. In a further molecular dissection of the active defense pathway, a sharp decline in transcription of several genes involved in pathogen resistance was found. After inoculation, transcription of MbNBS (an R gene), MdNPR1 (NPR1 gene) and PR3 (a typical PR gene) was below basal transcription in

Book Description
This book provides a comprehensive guide to the large number of diseases, disorders and injuries that can cause severe economic losses to banana, abacá and enset crops, and the fungi, bacteria, phytoplasmas, viruses, nematodes and abiotic factors involved. The monoculture of certain banana cultivars in large plantations make the crop particularly susceptible to catastrophic losses from disease and smallholders can also experience major problems. New approaches to breeding, crop management and handling are being developed to meet challenges posed by emerging threats. Handbook of Diseases of Banana, Abacá and Enset both describes and illustrates diseases and is printed in full colour throughout, creating a valuable diagnostic tool. It covers: - The origin and classification of banana, the safe movement of Musa germplasm and banana breeding for disease resistance. - Recent areas of growing research on the most important diseases of banana, such as black leaf streak, Fusarium wilt, Xanthomonas bacterial wilt and bunchy top. - Significant advances relating to pathogens causing less serious and widespread diseases. Authored by an international team of experts, this is an essential reference for all 'banana doctors' around the world. It serves as a useful field and laboratory guide, as well as a source of information for all those investigating diseases of banana, abacá and enset crops.

Book Description
Mobile phones are close to ubiquitous in developing countries; Internet and broadband access are becoming commonplace. Information and communication technologies (ICTs) thus represent the fastest, broadest and deepest technical change experienced in international development. They now affect every development sector – supporting the work of hundreds of millions of farmers and micro-entrepreneurs; creating millions of ICT-based jobs; assisting healthcare workers and teachers; facilitating political change; impacting climate change; but also linked with digital inequalities and harms – with the pace of change continuously accelerating. Information and Communication Technology for Development (ICT4D) provides the first dedicated textbook to examine and explain these emerging phenomena. It will help students, practitioners, researchers and other readers understand the place of ICTs within development; the ICT-enabled changes already underway; and the key issues and interventions that engage ICT4D practice and strategy. The book has a three-part structure. The first three chapters set out the foundations of ICT4D: the core relation between ICTs and development; the underlying components needed for ICT4D to work; and best practice in implementing ICT4D. Five chapters then analyse key development goals: economic growth, poverty eradication, social development, good governance and environmental sustainability. Each chapter assesses the goal-related impact associated with ICTs and key lessons from real-world cases. The final chapter looks ahead to emerging technologies and emerging models of ICT-enabled development. The book uses extensive in-text diagrams, tables and boxed examples with chapter-end discussion and assignment questions and further reading. Supported by online activities, video links, session outlines and slides, this textbook provides the basis for undergraduate, postgraduate and online learning modules on ICT4D.

Book Description
Innovation Platforms (IPs) form the core of many Agricultural Research for Development programmes, stimulating multi-stakeholder collaboration and action towards the realization of agricultural development outcomes. This book enhances the body of knowledge of IPs by focusing on mature IPs in agricultural systems research, including the crop and livestock sectors, and innovations in farmer cooperatives and agricultural extension services. Resulting from an international IP case study competition, the examples reported will help the many actors involved with agricultural IPs worldwide reflect on their actions and achievements (or failures), and find tools to share their experience. Chapters feature case studies from Central Africa, Ethiopia, India, Kenya, Nicaragua and Uganda. Authors reflect critically on the impact of IPs and showcase their progress, providing an important sourcebook and inspiration for students, researchers and professionals.
