A colleague at the Institute of Crop Breeding many years ago, S. V. Zonn, recalls the fame abroad of N.I. Vavilov in contrast to the oblivion to which for a time he was consigned in the Soviet Union. Vavilov opposed the harmful adventuristic projects announced by the evil paranoid “scientist” Lysenko. Among the many contributions of Vavilov, those to research for the development of deserts, largely forgotten, are here recalled. Vavilov organized the Office of Deserts, which established the Aral', Repetek, and Kara-Kalinsk experiment stations, which made major contributions to desert studies and which attracted able productive scientists. In practical work he organized work to provide fresh vegetables and fruits and green amenities to workers at the Balkhash copper combine and the urgently needed vegetables and vitamins to workers at the Bekdash salt works of the Kara-Bogaz-Gol of the Caspian Sea. He advocated scientific principles and applications free from the opportunism and adventurism which at one time flourished in Soviet biological sciences but which should not be repeated. “Recalling all that has happened to N.I. Vavilov, we preserve in our hearts his bright and uncompromising manner, which was devoted to science and society” (translated by Jay K. Mitchell, PlanEcon, Inc., Washington DC 20005).  相似文献

Academician N. I. Vavilov (1887-1943) served as president of the Geographical Society of the USSR from 1931 to 1940. A distinguished plant breeder, geneticist, explorer for wild ancestors of cultivated plants, and geographer, he traveled widely and reported regularly to the Society on his explorations and discoveries. Together with Yu. N. Shokal'skiy, then the honorary president, he brought many new initiatives to the activities of the Society. They arranged for the transfer of the Society from the People's Comissariat of Education of the RSFSR to the Academy of Sciences of the USSR. The First All-Union Congress of Geographers of the USSR was held in 1933, participation in international congresses was arranged, international co-operation was sponsored, membership was increased sharply, sections and commissions were established or revived, a series of public lectures was organized, a lecture hall was opened, and the scientific archives were enriched. Vavilov was especially interested in the work of the Section on History of Geographical Knowledge and participated actively in special issues of Izvestiya of the Society and in commemorative meetings at the Society devoted to individual geographers who had made particularly significant contributions to geographical knowledge (translated by Chauncy D. Harris, University of Chicago, Chicago, Illinois 60637-1583).  相似文献

Much has been published recently about Academician N.I. Vavilov, a seminal scientist with broad horizons. This article is limited to his geographical contributions and interests. His early study of agriculture in Afghanistan revealed his keen powers of field observation and his deep geographic orientation. This work won him the Przheval'skiy Gold Medal of the Geographical Society. He organized a network of experimental stations across the broad and diverse expanses of the Soviet Union to test the geographical limits of crops. He carried out numerous studies of mountain agriculture in many parts of the globe, noting that the isolation and the patchwork of critical environmental conditions in mountains favored the divergence of species, forms, and types of the wild ancestors of cultivated plants. This led to his trail-blazing identification and field investigation of hearths (centers) of origin of cultivated plants, of their diffusion, of areas of ancient agriculture, and to formulation of principles of geographical variability. This work has been continued in recent years by others. Vavilov had close connections with geography, with several geographers, and with the Geographical Society of the USSR (translated by Andrew R. Bond).  相似文献

Special attention is devoted to Vavilov's use of detailed maps for (a) recording initial results of field work in the study of local agriculture and ranges of domesticated plants in travels across several continents; and (b) presenting information about a large number of processes and phenomena in a concise way, affording the basis for their critical analysis and comparison. He was involved in programs to map Soviet and world agriculture (translated by Jay K. Mitchell, PlanEcon, Inc., Washington, DC 20005).  相似文献

As a professional and academic geographer in a Canadian university for the last fourteen years, I have become increasingly aware that there is a growing dichotomy between pure and applied research in physical geography. This breach has been discussed by numerous prominent figures in the field. Yet it is disquieting that many published statements amount to defences of the one or attacks on the other of these two aspects of the discipline. For example, Chorley has written: 'Utilitarian approaches to geomorphology will either result in large-scale work of which the intellectually-sterile taxonomic mapping is the most depressing precursor, or in a piecemeal concentration on small-scale realist systems. The construction of [realist] models in geomorphology may not be a secure base for geomorphological theory.' To Hails, by contrast, 'There seems little doubt that geomorphologists will be asked to resolve problems created by technological innovation and engineering design in the future … [Thus] the contribution of geomorphologists might be increased if the subject was taught in such a way that students were acquainted with the necessary techniques for scientific applied studies and the needs of the market place.'  相似文献
