How Did China Misplace 27000 Rivers?
Prior to conducting the water census, China estimated that it had upwards of 50,000 rivers inside of its borders. But the findings of the three-year study indicate that that number is actually 22,909. That's a loss of more than 27,000 rivers with a combined total water volume that would be about the equivalent of the Mississippi River. That is a significant amount of water to have completely vanished.
So what exactly happened to all of those rivers? China blames their disappearance on two factors – outdated mapping techniques and global climate change. In an interview with the South China Morning Post, China's Deputy Director of the Ministry of Water Resources, Huang He, indicated that the original estimate was probably too high due to inaccurate topographic maps that trace their origin back to the 1950s. He also acknowledged that climate change has led to the loss of both water and soil throughout China.
Considering how quickly China's population continues to grow and its towns and cities are modernizing, there is great fear that the nearly 23,000 rivers that do exist there will not be adequate to meet the demands placed on them in the 21st century and beyond. To make matters worse, many of those rivers are already greatly polluted, which will likely lead to a host of other health problems in the future.
China won't be the only nation dealing with water shortages in the future if climatologists are to be believed. Climate change is drying up rivers all over the world, not to mention shifting weather patterns and causing droughts. The difference is that most other countries don't have a population anywhere close to the size of China's and most aren't inflicting as much damage on their waterways as the Asian country.
Predicting what the future holds is a difficult proposition. But lets hope that when China takes its Second National Census of Water it doesn't lose more than half of its waterways once again.
