This open access book covers a century of research on wheat genetics and evolution, starting with the discovery in 1918 of the accurate number of chromosomes in wheat. We re-evaluate classical studies that are pillars of the current knowledge considering recent genomic data in the wheat group comprising 31 species from the genera Amblyopyrum, Aegilops, Triticum, and other more distant relatives. For these species, we describe morphology, ecogeographical distribution, phylogeny as well as cytogenetic and genomic features. For crops, we also address evolution under human selection, namely pre-domestication cultivation and domestication. We re-examine the genetic and archeological evidence of where, when, and how domestication occurred. We discuss unique aspects of genome evolution and maintenance under polyploidization, in natural and synthetic allopolyploids of the wheat group. Finally, we propose some thoughts on the future prospects of wheat improvement. As such, it can be of great interest to wheat researchers and breeders as well as to plant scientists and students interested in plant genetics, evolution, domestication, and polyploidy.

Food price volatility is one of the major challenges facing the global agricultural system today. This was most vividly illustrated during the global food crisis of 2007–9 when price spikes occurred for key staple food commodities—such as wheat, rice, maize, and soybeans. Given the variety of reactions by governments of countries experiencing similar food price shocks, the 2007–9 crisis offered an excellent natural experiment for generating knowledge on responses to price volatility in particular and on the political economy of agricultural policy-making more generally. This book contains the wealth of collaborative research by a global team of experts on food price policy—the research was undertaken on a sizeable group of low- and middle-income countries that were highly affected by the 2007–9 food crisis. The central aim of the study is to uncover which political economy factors—ranging from the constellation of different interest groups to the nature of political institutions—explain variations in policy responses across countries. The research output proves valuable for at least three target audiences. First, it can inform international organizations and donors about which types of policy interventions can mitigate price volatility and whether they are feasible given a country’s political economy context. Second, it can help national policy makers better understand the trade-offs of certain policy interventions. Third, it generates much-needed further knowledge about the agricultural policy-making process in developing countries, which remains incredibly scarce despite the importance of agriculture to these countries’ economies.

This book provides a review of precision agriculture technology development, followed by a presentation of the state-of-the-art and future requirements of precision agriculture technology. It presents different styles of precision agriculture technologies suitable for large scale mechanized farming; highly automated community-based mechanized production; and fully mechanized farming practices commonly seen in emerging economic regions. The book emphasizes the introduction of core technical features of sensing, data processing and interpretation technologies, crop modeling and production control theory, intelligent machinery and field robots for precision agriculture production.

In the years between the two world wars of the twentieth century leaders in Western countries worried about a food surplus. The hardships of the Great Depression were intensified by a glut of wheat and consequent low prices on the world market. Yet at the same time nutrition scientists protested that significant proportions of populations, even in affluent countries, were unable to afford a diet ‘adequate for health’. Fresh fruits, vegetables, dairy products and meat were out of reach for the poor. This book traces the work of three men who sought to bring together the interests of farmers and the needs of the hungry: scientist and passionate campaigner for better nutrition, John Boyd Orr; Australian politician and international statesman, Stanley Melbourne Bruce; and Economic Adviser to Bruce at the Australian High Commission in London, Frank Lidgett McDougall. Bruce once said ‘McDougall brings me a new idea every morning’. One of those ideas became the genesis of their work, which helped bring about the formation of the Food and Agriculture Organization of the United Nations in 1945. All three undertook significant roles in the formative years of the organisation. The story of this contribution to the international world order is little known. The cooperation, diplomacy and persistence of these men provides inspiration for tackling the alarming prospect of food shortages in the present century.
