Georgian Academy of Agricultural Sciences announces with deep sorrow that the outstanding scientist in the agricultural field, Honored Forester of Georgia and a prominent representative of the well-known Georgian Forestry Scientific School, laureate of the Academician T. Davitaia Prize, full member Academician of the Georgian Academy of Agricultural Sciences, Doctor of Agricultural Sciences, Professor Revaz Chagelishvili passed away at the age of 88.
Georgian agrarian scientists are well aware of the scientific, pedagogical and public activities of an outstanding forester of Georgian forests, Academician Revaz Chagelishvili.
Mr. Revaz Chagelishvili graduated with honors from the Faculty of Forestry of Georgian Agricultural Institute in 1961, majoring in Forestry Engineering. In 1962, he began working at the Forestry Institute of the Georgian Academy of Sciences. In 1968, he defended his candidate's thesis and was awarded the scientific degree of Candidate of Agricultural Sciences. In 1985, he defended his doctoral dissertation at V. Sukachev Forest and Timber Institute of the Siberian Branch of the USSR Academy of Sciences, Krasnoyarsk, and was awarded the scientific degree of Doctor of Agricultural Sciences.
Revaz Chagelishvili, a scientist, was a person with a rich work biography. He began his work at the Forestry Institute as a senior laboratory assistant, followed by the position of a research worker, senior research worker. In 1976-1991, he headed the laboratory studying the social and ecological functions of forests, was the deputy chairman of the “Ecology” section of the Forest Problem Council of the Academy of Sciences of the former USSR. For a long time, he led topics of all-Union importance on topical issues of mountain forestry. For 10 years, he conducted research with scientists from the Federal Forestry Institute in Vienna, Austria, in order to study the protective functions of mountain forests.
In 1991, Mr. Revaz was elected a professor at the Georgian Agrarian University, where he lectured on ecology and nature protection at the Department of Nature Protection and General Forestry.
In 1994, he was elected a corresponding member of the Georgian Academy of Agricultural Sciences, and in 1995 - a full member of the same academy - academician.
From May 1991 to April 2004, Academician Revaz Chagelishvili was the Deputy Minister of Environment and Natural Resources Protection of Georgia.
In 2016, he was elected a member of the Presidium of the Georgian Academy of Agricultural Sciences and Academician-Secretary of the Scientific Department of Forestry, which he headed until 2023.
Academician Revaz Chagelishvili was the author of 164 scientific works, including 3 monographs, 11 textbooks and 1 recommendation. His works mainly concerned the issues of forestry, forestry, forest hydrology, forest ecology and nature protection. The monograph “Avalanche Protective Function of Mountain Forests and Measures to Combat Snow Avalanches” was awarded the Acad. T. Davitaia Prize in 1984.
Under the leadership and direct participation of Mr. Revaz, many long-term stationary research facilities were organized in separate regions of Georgia with different soil and climatic conditions. Based on the results of the study, Revaz Chagelishvili determined the quantitative and qualitative indicators of solid and liquid runoff from watersheds with different percentages of forest cover in conditions of insufficient moisture in Eastern Georgia and excessive moisture in the West. The optimal forest cover of Georgian mountain forests for different regions was determined.
The results of the hydrological, phyto-cenological, and geomorphological study of the forest processed by R. Chagelishvili at the level of small watersheds formed the basis for his classification of watersheds in terms of their ecological functions. A set of measures was developed for individual classes, which are a contributing factor in terms of enhancing the positive impact of mountain forests on the environment.
He was the first to study the effects of various systems of felling on the soil protection and water regulation functions of mountain forests, substantiated the characteristics of the deterioration of the physical and water-conducting properties of the soil in felled groves in terms of time and the parameters of the duration of restoration of these properties in ecosystems.
Academician R. Chagelishvili developed an original method for assessing the protective functions of avalanche-prevention forest massifs. Based on the materials of a long-term complex
