Briefings

Lake Baikal, the world's largest freshwater lake by volume, has recovered from a century-long decline due to aridification spreading across East Asia. It holds approximately 20% of global surface freshwater and was designated a UNESCO World Heritage site in 1996 for its biodiversity importance.

Key points

• Lake Baikal holds around 20% of the world's surface freshwater volume, making it the most voluminous freshwater lake globally.
• The lake was designated a UNESCO World Heritage site in 1996 specifically because of its critical role in biodiversity.

Context

Lake Baikal is located in Siberia and is one of the most important freshwater environments on Earth. Its recovery is significant given the broader context of aridification spreading across East Asia.

Limitations

Evidence covers only the lake's volume and historical designation status. It does not provide data on current water levels, specific recovery rates, or future climate projections.
