Abstract
Numerous rivers, lakes and other water features have suffered significant alterations as a result of human economic activity. As a result, hydrometric, hydrological, biological, ecological conditions, as well as morphometric elements of these objects were violated. In this regard, Lake Sevan and its basin might be used as a well-known example. There has never been any instance in the history of limnology where a lake’s level was artificially lowered by 18 meters over 3 to 4 decades (1930–1970), and by another 2 meters at the end of the 20th century (1990–2000). Additionally, the lake’s water volume dropped from 58 billion m3 to 32 billion m3. The Sevan problem first surfaced in the late 19th and early 20th centuries and is still a problem today. However, it has many meanings/soundings at different times. Based on this, we usually divided the entire study period into several stages. It should be noted that the ecosystem has suffered irreparable losses as a result of the use of the Lake Sevan resources, inadequate water resource management, and both positive and negative effects of these factors. We disagree with the assertions of many experts that problems can only be prevented or solved by raising the lake level. Therefore, extensive actions must be taken in the Sevan basin management area, regardless of the lake’s level.
期刊介绍:
Journal “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” is founded by the Faculty of Geography of Lomonosov Moscow State University, The Russian Geographical Society and by the Institute of Geography of RAS. It is the official journal of Russian Geographical Society, and a fully open access journal. Journal “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” publishes original, innovative, interdisciplinary and timely research letter articles and concise reviews on studies of the Earth and its environment scientific field. This goal covers a broad spectrum of scientific research areas (physical-, social-, economic-, cultural geography, environmental sciences and sustainable development) and also considers contemporary and widely used research methods, such as geoinformatics, cartography, remote sensing (including from space), geophysics, geochemistry, etc. “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” is the only original English-language journal in the field of geography and environmental sciences published in Russia. It is supposed to be an outlet from the Russian-speaking countries to Europe and an inlet from Europe to the Russian-speaking countries regarding environmental and Earth sciences, geography and sustainability. The main sections of the journal are the theory of geography and ecology, the theory of sustainable development, use of natural resources, natural resources assessment, global and regional changes of environment and climate, social-economical geography, ecological regional planning, sustainable regional development, applied aspects of geography and ecology, geoinformatics and ecological cartography, ecological problems of oil and gas sector, nature conservations, health and environment, and education for sustainable development. Articles are freely available to both subscribers and the wider public with permitted reuse.
