Book excerpt: 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.

This book was released on 2021-06-17 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Of the global population of more than 7 billion people, some 800 million do not have enough to eat today. By 2050, the population is expected to exceed 9 billion. It has been estimated that some 15% of food production is lost to plant diseases; in developing countries losses may be much higher. Historically, plant diseases have had catastrophic impact on food production. For example: potato blight caused the Irish famine in 1845; brown spot of rice caused the Great Bengal Famine of 1943; southern corn leaf blight caused a devastating epidemic on the US corn crop in 1970. Food security is threatened by an ongoing sequence of plant diseases, some persistent for decades or centuries, others more opportunistic. Wheat blast and banana xanthomonas wilt are two contrasting examples of many that currently threaten food production. Other emerging diseases will follow. The proposed title aims to provide a synthesis of expert knowledge to address this central challenge to food security for the 21st century.

Book excerpt: Food Crop Production by Smallholder Farmers in Southern Africa: Challenges and Opportunities for Improvement evaluates traditional cultivation practices used by smallholder farmers, providing a synthesis of the latest information on increasing crop yield through adoption of research innovations. The book catalogs smallholder cultivation practices and recommends innovative strategies for improving the agriculture sector including: management practices that reduce net carbon emissions; technologies that improve soil structures and conserve the natural resources base; means of empowering female resources along value chains; and government commitment to adopt policies that enhance agriculture productivity by encouraging farmers to use environmentally sound cultivation technologies. Traditional farming techniques often produce negative impacts on the environment and ecosystem resulting in outbreaks of diseases and pests. In addition to the region’s recurrent droughts, these outbreaks of numerous diseases and pests, weeds and other invasive plants put thousands at risk of poverty and hunger, as well as malnutrition. This book presents enhanced agricultural production technologies for ensuring adequate food production, safety and nutritional quality for the population of Southern Africa and forms the basis for an increased SADC regional effort in food production through which financial and trade institutions can improve stakeholder capacities, encourage micro-enterprise development and enhance employment and regional trade. Provides a critical synthesis of data and information for increasing crop yield through adoption of research innovations Evaluates traditional and scientific interventions that address food security issues of the poor farmers in the region Presents agro-ecologies of countries in the region and how they relate to various cultivation practices Catalogs smallholder cultivation practices and recommends innovative strategies for improving the agriculture sector

Available in PDF, EPUB and Kindle. Book excerpt: 'The benefit of teaching life skills is that I also changed. If I can make a difference in the life of just one child, I will be happy' When we think about Africa, we often recall pictures of a wild countryside, rivers, forests, deserts, buzzing markets and media stories of poverty, devastation and hunger - a prime continent where branches of human justice are still thin and often absent. Those of us who have made Africa our destination are witness to a different experience as we meet people who charter a life of resilience and construct a social world of their own. Extended family ties stretch far and deep and so do family feuds, political turmoil and the many manifestations of poverty - painting a human canvas on which development programs (including sport-for-development) need to blend in strokes for reciprocal change. The GIZ/YDF program is possibly one of the most significant programs in terms of philosophy, methodology and scope that sheds light on development work as it is embraced, transformed and assimilated into real-life experiences. It is at this embedded level of social uptake that the selected 15 stories in the text and the detailed 45 stories on the CD articulate real-life experiences as told by program participants, peer- educators and YDF partners who took up the responsibility and challenge to change lives for the better. Multiple voices give an expression to the meaning and dynamics of sports-related interventions as they affect individuals within a myriad of social relationships and contexts. The uniqueness of this publication is that it not only captures all these voices to constitute stories from nine African countries, but validates a ripple of impact where context is a prism for seeing and knowing. How do real people see and benefit from a sport-for-development program? How does the North meet the South in partnership and trust? After reading these stories, you will not merely see young boys or girls kicking a ball and appreciate the novel aesthetics, but you will smell the dust and know it is a family and community at play. You will realize that aspirations and expectations are born from a need for entitlement in a field where the pitch is only the beginning of a journey. May this brief encounter do justice to all who shared their lives with such honesty and hope.

Book excerpt: The series Tasks for Vegetation Science is devoted to a variety of research aspects in vegetation science, pure as wellas applied. Of the applied problems one of the most pressing is to achieve better knowledge and improvement of the pasture vegetation in tropical and subtropical regions. As series editor I was impressed by the sheer volume of useful scientific information concerning pasture plants from East Africa collected during many years by Dr. Boonman and compiled in one manuscript. Dr. Boonman first came to East Africa in 1963 on an overland journey along the river Nile which took him from Alexandria in Egypt to Lake Victoria in Uganda and Kenya and back again. After a brief spell as a cotton agronomist in the Sudan Gezira he joined the grassland research team at Kitale, Kenya in 1966. Improvement ofseed yield oftropical grasses was his principal interest which finally led him into the fieldof breeding grasses. Well-known varieties from his work include Boma & Elmba Rhodesgrass as wellas Clone 13Elephantgrass. In 1979he was recalled to The Netherlands to head a cooperative seedcompany involved in the breeding of grasses and cereals. The author has focused this study on one region, Eastern Africa.Global application of theories runs into conflicts too easily with local types of farming, if not with bare economics. Very few books can be found that describe existing practices and seek local answers by digging deep in the stacks of old, local reports.
