Lake Baikal, the oldest and deepest lake in the world located in southern Siberia, has become a major travel destination, a site of scientific research, and increasingly a major concern regarding its decline. The Baikal region is home to 12% of the world’s fresh water and it is estimated that 17% of all species found in the lake are unique; however, recent reports have indicated that Lake Baikal is shrinking and if the decline continues, this greatly impacts the environment and the people living in the area and in the entire region.<\/p>\n

Bringing to focus this environmental concern, a research conducted by the Hydrology and Ecosystem Research Institute at Baikal observed that the water surface is declining by an average of 4-6 cm every year. This has been largely attributed to the changing climate, resulting in higher temperatures and drier summers. The researchers mention that for over 20 years—since 1996—snow cover has been declining, thus impacting the lake’s water levels. This has been mainly because of the lack of precipitation in winter, leading to the snow melting faster than what it used to in the past.<\/p>\n

The lake’s size has been decreasing significantly over the past few decades. Data collected since 1989 shows that the Baikal’s water volume has been decreasing by 0.14 km3<\/sup>. Consequently, this has led to the lake’s edge retreating by 1.27 km and the volume has dropped by 0.93 km3<\/sup>.<\/p>\n

Dr. Shilova, an associate professor at the University of Wisconsin-Madison’s Center for Limnology and lead author of the research article about the declining Lake Baikal, states that the water volume in Lake Baikal is decreasing rapidly, threatening both its biodiversity and the people who depend on it for tourism, industry, and fishing. She further mentions that the warming temperatures and changing climate are leading to a decline in the lake’s water level, which is worrying, especially when it comes to the sustainability of the lake.<\/p>\n
