This book is open access under a CC BY 4.0 license. This book provides a fresh, updated and science-based perspective on the current status and prospects of the diverse array of topics related to the potato, and was written by distinguished scientists with hands-on global experience in research aspects related to potato. The potato is the third most important global food crop in terms of consumption. Being the only vegetatively propagated species among the world’s main five staple crops creates both issues and opportunities for the potato: on the one hand, this constrains the speed of its geographic expansion and its options for international commercialization and distribution when compared with commodity crops such as maize, wheat or rice. On the other, it provides an effective insulation against speculation and unforeseen spikes in commodity prices, since the potato does not represent a good traded on global markets. These two factors highlight the underappreciated and underrated role of the potato as a dependable nutrition security crop, one that can mitigate turmoil in world food supply and demand and political instability in some developing countries. Increasingly, the global role of the potato has expanded from a profitable crop in developing countries to a crop providing income and nutrition security in developing ones. This book will appeal to academics and students of crop sciences, but also policy makers and other stakeholders involved in the potato and its contribution to humankind’s food security.

The potato has the potential to raise smallholder income and improve food security in Eastern Africa. While improving the quality of seed potatoes can contribute to increasing its productivity, most farmers largely rely on the seed potatoes they save themselves. Seed potato system interventions need to address the quality of specially multiplied and farm-saved seed potatoes simultaneously. This book shows that positive selectionthe selection of healthy looking mother plants for the production of seed potatoes by aware potato farmerscan contribute to improving seed potato quality and the quality of the subsequent harvest.

Sweetpotato and potato are expanding faster than any other food crops in sub-Saharan Africa. There is growing investment in research to address bottlenecks in value chains concerning these two crops, and growing interest from the private sector in investing in them. This book addresses five major themes on sweetpotato and potato: policies for germplasm exchange, food security and trade in Africa; seed systems; breeding and disease management; post-harvest management, processing technologies and marketing systems; nutritional value and changing behaviours.

In many developing countries, smallholder farmers cultivating vegetatively propagated crops (VPCs) have limited access to quality planting material. This constraint can limit both the yield of and returns on VPC cultivation. Yet policy and regulatory initiatives designed to strengthen access to quality VPC planting materials have been relatively unsuccessful to date. Part of the problem is the unique biological and economic characteristics of vegetative propagation and its distinctness from cereal crops, which dominate narratives on seed system reforms. Drawing on qualitative analysis of policy and practice, this study examines reform options related to quality assurance regulations in four crop-country combinations: cassava in Nigeria and Vietnam, and potato in Kenya and Vietnam. The study highlights theory and evidence on existing models of regulation; alternative models that may better incentivize cost-effective multiplication and distribution; and recommendations for policy, regulation, and investment in VPC seed markets. Findings indicate that regulations designed around strict and centralized quality control systems tend to limit market size, while more localized production systems are limited by both capacity and reach. These findings suggest the need for alternatives that balance a permissive regulatory regime with decentralized production systems, grassroots capacity development, market surveillance, and systems that integrate internal (producer-level) quality assurance with external (regulatory) quality assurance.

This book provides basic knowledge on how to produce, multiply and use propagation material in seed potato production and supply systems world wide. Healthy, vigorous seed tubers are essential in potato production. Producing them used to be expensive and difficult. Multiplication rates in the field are low, seed-borne diseases are numerous and seed tubers lose quality during storage between growing seasons. Recently, novel methods of multiplication have revolutionised the seed potato industry. This has resulted in a diversity of seed production systems adjusted to the local potential and needs. This book summarises the current knowledge and assesses the efficient use of modern technology in different stages of seed production. It describes in detail what seed quality means, how (pre-)basic seed can be produced, how this can be multiplied, and how seed health is maintained. It also describes diverse examples of seed supply systems in different regions of the world. The book is aimed at agronomists, farm advisors, seed producers, breeders, and at those involved in seed policies, seed programme development and seed trade. Also recommended for (international) students in agronomy, horticulture and plant breeding.

Potato is a crop grown on all inhabited continents of the globe. It is included in the top five crops of the world, used as staple food in several countries, and the number of people daily consuming the potato may surpass one billion. Despite the high quantities of seed potato produced worldwide, there are yield gaps due to challenges such as abiotic stresses, pests, climate change and poor production practices. A region-wide critical analysis of yield declining factors can help formulate management strategies that can improve potato yields. Bridging yield gaps in potato will ultimately ensure the role of this crop in securing current and future food security. Potato Production Worldwide presents information on this global crop from its history, morphology, and taxonomy to the growth and development of the potato crop, including the latest strategies in addressing today’s biotic and abiotic challenges. This book identifies the reasons for yield gaps in various potato production regions of the world, as well as presenting the best production practices, pest management strategies and approaches to deal with climate change from the perspective of potato production. Chapters provide important insights into potato production cultures and approaches in the major potato production countries. Potato Production Worldwide will be a valuable resource for researchers, scientists and students seeking a comprehensive view of successful potato production. Provides comprehensive information on the origin, history, taxonomy, morphology, ecophysiology, growth and development of the potato Addresses production practices, including irrigation, nutrient management, harvesting and post-harvest techniques Explores the impact of Abiotic stresses (drought, chilling, salinity etc.) and their management

In most developing countries, good quality seed is hard to obtain and farmers struggle to save seed from one year to the next. This title takes a people-centred look at the companies, public agencies and family farms that are taking on this role and making a difference to food security across Africa.
