In this study, we examine whether the adoption of late blight resistant cultivars has an effect on yields and fungicide use. We will focus on the Amarilis variety which is considered more resistant to late blight than other varieties adopted by the farmers in the sample. Using data from three main potato producer states in the Peruvian Andes, significant positive effects on yields and negative effects on fungicide use are found. Specifically, the damage abatement approach provides evidence that Amarilis adoption enhances output maximization mainly through the control of late blight. At the discount rate of 10%, the probable net present value (NPV) of the net benefits accruing to farmers through the adoption of Amarilis amounts to almost 9 million dollars.

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.

The present guide is designed to assist professionals and technicians in charge of evaluation trials designed to screen selected potato genotypes for resistance to this disease. The evaluation of breeding families, which is carried out under greenhouse or field conditions, can use the same methodology. The guide can help to organize trials, improve data collection and analysis and introduces new criteria for resistance measurement based on epidemiological principles.

Experts discuss the challenges faced in agrobiodiversity and conservation, integrating disciplines that range from plant and biological sciences to economics and political science. Wide-ranging environmental phenomena—including climate change, extreme weather events, and soil and water availability—combine with such socioeconomic factors as food policies, dietary preferences, and market forces to affect agriculture and food production systems on local, national, and global scales. The increasing simplification of food systems, the continuing decline of plant species, and the ongoing spread of pests and disease threaten biodiversity in agriculture as well as the sustainability of food resources. Complicating the situation further, the multiple systems involved—cultural, economic, environmental, institutional, and technological—are driven by human decision making, which is inevitably informed by diverse knowledge systems. The interactions and linkages that emerge necessitate an integrated assessment if we are to make progress toward sustainable agriculture and food systems. This volume in the Strüngmann Forum Reports series offers insights into the challenges faced in agrobiodiversity and sustainability and proposes an integrative framework to guide future research, scholarship, policy, and practice. The contributors offer perspectives from a range of disciplines, including plant and biological sciences, food systems and nutrition, ecology, economics, plant and animal breeding, anthropology, political science, geography, law, and sociology. Topics covered include evolutionary ecology, food and human health, the governance of agrobiodiversity, and the interactions between agrobiodiversity and climate and demographic change.

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.

In the tradition of Silent Spring, Raoul Robinson's Return to Resistance calls for a revolution. Traditional plant breeding techniques have led us to depend more and more on chemical pesticides to protect ourcrops. Return to Resistance shows gardeners, farmers, and plant breeders how to use a long-neglected technique to create hardy new plant varieties that are naturally resistant to pests and disease. Horizontal resistance breeding has been largely ignored in this century due to the popularity and apparent successes of the Mendelian geneticists. However the colossal, unrecognized failure of m.

During the International Year of the Potato, celebrated in 2008, FAO and the International Potato Center helped forge partnerships worldwide to address critical aspects of sustainable potato production. This technical guide collates that experience to review technical, socio-economic, policy and institutional factors that currently constrain increased potato production and productivity in tropical and sub-tropical countries. it presents Good Agriculture Practices relevant to potato production, and indicators and recommendations for action in key areas. It outlines a new policy and research agenda for the potato subsector that aims at making a real contribution to the eradication of hunger and poverty.
