In 1975 he defended a PhD at MSU, and in 1987 - his doctoral thesis. In 1997 he was awarded the academic title Professor in the specialty biogeochemistry. Since 1971 he works at the Pushchino Scientific Center of Biological research of the Russian Academy of Sciences. For several years he taught in different universities of the world, in particular, at Cornell University, USA, Seoul National University, Korea, Royal University of Technology Bangkok, Thailand, M. V. Lomonosov Moscow state University, Russia. Currently, he is principal researcher of the Institute of physicochemical and biological problems of soil science of RAS, also part-time chief scientific officer of LLC Gazprom VNIIGAZ. Scientific interests of Professor V. N. Bashkin include biogeochemistry, systems analysis, geo-ecological risk of transboundary transfer of polluting substances, the remediation of contaminated territories. Great attention is paid to the development of innovative biogeochemical technologies. V. N. Baskin published more than 40 books in English, Chinese and Russian domestic and foreign publishing houses, he is the author and coauthor of more than 300 scientific articles published in leading scientific journals, received 16 patents. He has supervised 5 doctoral and 20 PhD theses in different countries of the world. Prof. V. N. Bashkin is member of the editorial Board of 5 international journals. For several years he was the Deputy Chairman of the Working Group on Effects (scientific Committee) of the UN Long-Range Transboundary Air Pollution Convention.Book Description:This proposed and edited volume will be devoted to one of the most popular topics of modern ecological and environmental sciences. This book focuses on the alterations in ecological and biogeochemical cycling in impacted polar land and water ecosystems, where a significant part of natural gas and oil production is developing both in Russia and in many other countries. In the near future, these will make great progress. Founded on the field monitoring of various biogeochemical cycle parameters of polar ecosystems and relevant changes in ecological indexes and indicators, the authors suggest new biogeochemical technologies for assessing and managing environmental and geoenvironmental risks in severe climate conditions.This issue is meant for a wide range of scientists, specialists and practitioners in ecological science, biogeochemistry and energy sectors, and may be quite useful to undergraduate and postgraduate students who study the fundamental principles of ecosystem sustainability and anthropogenic impact.Target Audience:This issue is meant for a wide range of scientists, specialists and practitioners in ecological science, biogeochemistry and energy sector and may be quite useful to undergraduate and postgraduate students and masters, who study the fundamental principles of ecosystem sustainability at the anthropogenic impact.
