Hsu publishes article about China's 28,000 lost rivers
As recently as 20 years ago, there were an estimated 50,000 rivers in China, each covering a flow area of at least 60 square miles. But now, according to China's First National Census of Water, more than 28,000 of these rivers are missing. To put this number into context, China's lost rivers are almost equivalent, in terms of basin area, to the United States losing the entire Mississippi River.
Why have these rivers "vanished" from the maps and national records?
Official explanations from the Chinese government have attributed the significant reduction to statistical discrepancies, water and soil loss, and climate change.
"The disparity in numbers was caused mainly by inaccurate estimates in the past, as well as climate change and water and soil loss. Due to limited technology in the past, the previous figures were estimated using incomplete topographic maps dating back to the 1950s," said Huang He, China's Deputy Director of the Ministry of Water Resources, in an interview with the South China Morning Post.
