The Colorado River is about 2.3 thousand kilometers long, flowing through the Grand Canyon in the United States, ceased to reach the California Pacific Bay.

Researchers from Sustainable Waters have established: over 100 years, colorado water content has decreased by 20%. Scientists received such results by analyzing the average annual water use and water loss and compiling the first full water budget of the river.

The main reason for a decrease in the volume of water in Colorado is an excessive water fence for agricultural needs. For more than 16 years, the Colorado River suffered from excessive use by man, scientists report. Now from Colorado they consume an average of 23.7 billion cubic meters of water annually, the river serves as a source of water for 40 million Americans and Mexicans, and about 2 million hectares of arable land depends on it. In most cases, people take water from Colorado for irrigation - it accounts for 74% of cases of using river water. But even if people reduce water consumption, the river will not be able to return to the previous direction, the researchers say.

Another important factor is the global climate change. Earlier studies showed : an increase in temperature in the region by 1.4 ° C over the past century has reduced the annual amount of water in the river by more than 11%.

“We hope that a new study will help public dialogue and political negotiations regarding the distribution and reduction of water in the River of the Colorado River, which are currently underway. <...> Knowledge where the water [from Colorado] goes is important when developing a policy of bringing the pool to a sustainable balance of water supply and supply, ”the researchers concluded .
