His knowledge, tenacity and eloquence still resound in the corridors of the Saint Petersburg institute that bears his name, and his spirit continues to inspire the hundreds of researchers pursuing his work. Nikolai Vavilov anticipated the disappearance of plant diversity and within the space of a few decades through study and travel all over the world he found the means of saving it. For political and ideological reasons, Vavilov was condemned to death and left to starve in the dungeon of a Soviet prison. Gradually, on both sides of the iron curtain, his memory began to fade. One hundred years after Vavilov's first expedition, the photographer Mario Del Curto retraced his footsteps. For four years he met with those who, despite overwhelming obstacles, perpetuate Vavilov's seed prospecting, selection and conservation work in order to save the planet's staple food crops. This book is the unprecedented story of his journey to the heart of the Vavilov Institute and its twelve research stations. International specialists bring light the huge scope of the work undertaken by Vavilov and his successors.

In The Murder of Nikolai Vavilov, acclaimed journalist and author Peter Pringle recreates the extraordinary life and tragic end of one of the great scientists of the twentieth century. In a drama of love, revolution, and war that rivals Pasternak's Dr. Zhivago, Pringle tells the story of a young Russian scientist, Nikolai Vavilov, who had a dream of ending hunger and famine in the world. Vavilov's plan would use the emerging science of genetics to breed super plants that could grow anywhere, in any climate, in sandy deserts and freezing tundra, in drought and flood. He would launch botanical expeditions to find these vanishing genes, overlooked by early farmers ignorant of Mendel's laws of heredity. He called it a "mission for all humanity." To the leaders of the young Soviet state, Vavilov's dream fitted perfectly into their larger scheme for a socialist utopia. Lenin supported the adventurous Vavilov, a handsome and seductive young professor, as he became an Indiana Jones, hunting lost botanical treasures on five continents. In a former tsarist palace in what is now St. Petersburg, Vavilov built the world's first seed bank, a quarter of a million specimens, a magnificent living museum of plant diversity that was the envy of scientists everywhere and remains so today. But when Lenin died in 1924 and Stalin took over, Vavilov's dream turned into a nightmare. This son of science was from a bourgeois background, the class of society most despised and distrusted by the Bolsheviks. The new cadres of comrade scientists taunted and insulted him, and Stalin's dreaded secret police built up false charges of sabotage and espionage. Stalin's collectivization of farmland caused chaos in Soviet food production, and millions died in widespread famine. Vavilov's master plan for improving Soviet crops was designed to work over decades, not a few years, and he could not meet Stalin's impossible demands for immediate results. In Stalin's Terror of the 1930s, Russian geneticists were systematically repressed in favor of the peasant horticulturalist Trofim Lysenko, with his fraudulent claims and speculative theories. Vavilov was the most famous victim of this purge, which set back Russian biology by a generation and caused the country untold harm. He was sentenced to death, but unlike Galileo, he refused to recant his beliefs and, in the most cruel twist, this humanitarian pioneer scientist was starved to death in the gulag. Pringle uses newly opened Soviet archives, including Vavilov's secret police file, official correspondence, vivid expedition reports, previously unpublished family letters and diaries, and the reminiscences of eyewitnesses to bring us this intensely human story of a brilliant life cut short by anti-science demagogues, ideology, censorship, and political expedience.

The future of our food depends on tiny seeds in orchards and fields the world over. In 1943, one of the first to recognize this fact, the great botanist Nikolay Vavilov, lay dying of starvation in a Soviet prison. But in the years before Stalin jailed him as a scapegoat for the country’s famines, Vavilov had traveled over five continents, collecting hundreds of thousands of seeds in an effort to outline the ancient centers of agricultural diversity and guard against widespread hunger. Now, another remarkable scientist—and vivid storyteller—has retraced his footsteps. In Where Our Food Comes From, Gary Paul Nabhan weaves together Vavilov’s extraordinary story with his own expeditions to Earth’s richest agricultural landscapes and the cultures that tend them. Retracing Vavilov’s path from Mexico and the Colombian Amazon to the glaciers of the Pamirs in Tajikistan, he draws a vibrant portrait of changes that have occurred since Vavilov’s time and why they matter. In his travels, Nabhan shows how climate change, free trade policies, genetic engineering, and loss of traditional knowledge are threatening our food supply. Through discussions with local farmers, visits to local outdoor markets, and comparison of his own observations in eleven countries to those recorded in Vavilov’s journals and photos, Nabhan reveals just how much diversity has already been lost. But he also shows what resilient farmers and scientists in many regions are doing to save the remaining living riches of our world. It is a cruel irony that Vavilov, a man who spent his life working to foster nutrition, ultimately died from lack of it. In telling his story, Where Our Food Comes From brings to life the intricate relationships among culture, politics, the land, and the future of the world’s food.

Darwin's Harvest addresses concerns that we are losing the diversity of crop plants that provide food for most of the world. With contributions from evolutionary biologists, geneticists, agronomists, molecular biologists, and anthropologists, this collection discusses how economic development, loss of heirloom varieties and wild ancestors, and modern agricultural techniques have endangered the genetic diversity needed to keep agricultural crops vital and capable of adaptation. Drawing on the most up-to-date data, the contributors review the utilization of molecular techniques to understand crop evolution. They explore current research on various crop plants of both temperate and tropical origin, including maize, sunflower, avocado, sugarcane, and wheat. The chapters in Darwin's Harvest also provide solid background for understanding many recent discoveries concerning the origins of crops and the influence of human migration and farming practices on the genetics of our modern foods.

The theory of the Vavilov-Cherenkov radiation observed by Cherenkov in 1934 was created by Tamm, Frank and Ginsburg who associated the observed blue light with the uniform charge motion of a charge at a velocity greater than the velocity of light in the medium. On the other hand, Vavilov, Cherenkov's teacher, attributed the observed blue light to the deceleration of electrons. This has given rise to the appearance of papers in which the radiation of a charge uniformly moving in a finite space interval was related to the Bremsstrahlung arising at the end points of the motion interval. This monograph is intended for students of the third year and higher, for postgraduates, for professional scientists (both experimentalists and theoreticians) dealing with Vavilov-Cherenkov and synchrotron radiation. An acquaintance with the three volumes of the Landau and Lifshitz course (Quantum Mechanics, Classical Field Theory and Macroscopic Electrodynamics) is sufficient for understanding the text.

One of the world centers of crop evolution and origin, Ethiopia has long been recognized as an important area of diversity for several major and various minor crops. Based on an international conference held in Addis Ababa, this book describes how plant genetic diversity in Ethiopia is of vital importance in breeding new varieties of crops with desirable characteristics, such as increased resistance to pests and diseases and greater adaptation to heat and drought. The three main sections in the book consider the Ethiopian center of diversity, germ plasm or genetic material collection and conservation in Ethiopia, and the evaluation and utilization of Ethiopian genetic resources. A broad range of food and feed crops and plants of medicinal and industrial importance are discussed, both at a national and international level. A brief account of conservation strategies and gene bank problems unique to Ethiopia is also given. The importance of Ethiopia's plant genetic resources to world agriculture has been demonstrated on more than one occasion. Plant breeders, geneticists, and botanists throughout the world will, therefore, find this unique book a valuable source of information and an essential reference work.
