Kazakhstan and China – June 10th, 2013

Lakes in arid regions of Central Asia, such as Lake Balkhash, in Kazakhstan (upper left), northwest of China’s Taklamakan Desert (below), act as essential components of regional water cycles, providing sparse but valuable water resource for the fragile ecological environments and human lives.

Lakes in Central Asia are sensitive to climate change and human activities, and great changes have been found since 1960s. Mapping and monitoring these inland lakes can improve our understanding of mechanism of lake dynamics and climatic impacts. Satellite altimetry provides an efficient tool of continuously measuring lake levels in these poorly surveyed remote areas.

Scientists have shown that alpine lakes are increasing greatly in lake levels during 2003-2009 due to climate change, while open lakes with dams and plain endorheic lakes decrease dramatically in water levels due to human activities, which reveals the overexploitation of water resource in Central Asia (click here for more information).
