Maintaining food security in the face of human population increase and climate change is one of the critical challenges facing us in the 21st Century. Utilisation of the full range of agrobiodiversity will be a necessary tool in addressing this challenge. In this book a team of international contributors review all aspects of utilization and conservation of crop wild relative (CWR) and landrace (LR) diversity as a basis for crop improvement and future food security. This book will appeal to a wide array of specialists and postgraduate students, such as those working in the fields of agrobiodiversity conservation and use, conservation, ecology, botany, genetics, plant breeding and agriculture.

Potato (Solanum tuberosum L.) is grown in over 100 countries throughout the world. As a staple food, potato is the fourth most important crop after rice, wheat, and maize, and has historically contributed to food and nutrition security in the world. Global interest in potato increased recently as world food prices soared, threatening the global food security and stability. Unlike major cereals, potato is not a globally traded commodity, and prices are usually determined by local production costs. Thus, potato is increasingly regarded as a vital food-security crop and as a substitute for costly cereal imports. With such importance, the 29 chapters in the edited book address the issues of sustainable potato production. This book begins with an introduction on sustainable potato production and global food security, and then presents eight case studies selected globally and covering different issues relevant to sustainable potato production in both developed and developing countries.

Hunger, malnutrition, poor health, and deficient food systems are widespread in Sub-Saharan Africa. While much is known about African food systems and about African health and nutrition, our understanding of the interaction between food systems and health and nutrition is deficient. Moreover, the potential health gains from changes in the food system are frequently overlooked in policy design and implementation.The authors of The African Food System and its Interactions with Human Health and Nutrition examine how public policy and research aimed at the food system and its interaction with human health and nutrition can improve the well-being of Africans and help achieve the United Nations Millennium Development Goals (MDGs). Several of the MDGs focus on health-related challenges: hunger alleviation; maternal, infant, and child mortality; the control of HIV/AIDS, tuberculosis, and malaria; and the provision of safe water and improved sanitation. These challenges are intensified by problems of low agricultural and food system productivity, gender inequity, lack of basic infrastructure, and environmental degradation, all of which have direct and indirect detrimental effects on health, nutrition, and the food system.Reflecting the complexity and multidisciplinary nature of these problems and their solutions, this book features contributions by world-renowned experts in economics, agriculture, health, nutrition, food science, and demography.

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.
