Perez C. Not rule out tensions between Mexico and the United States by water shortages.
Newspaper La Jornada: 26/02/2012. Mexico City.
If climate trends continue and worsen the drought does not rule out further tensions between Mexico and the United States by the scarcity of water in the border said Roberto Salmon Castelo, head of the International Commission of Boundary and Water, warning that while there are no debts between the two countries with bilateral agreements related to “the payment of water”, it is necessary to find alternatives to comply with the commitments under the 1944 treaty and the convention of 1906, which determine the use and enjoyment of the waters of international rivers and in this case are common border.
“We are making mathematical projections so that, in case that arrives to reduce the water , see how would distribute. There are seven U.S. states and Mexico that we benefit from the Colorado River Basin and the Bravo River. The important thing is how haggling impact the event of a reduction in states that use the basin. The issue is how the distribution would be if the water is reduced. We agreed it will depend on the amount of water to be reduced by the impact of climate change. It was not easy, I think it’s at the point where most discussed but we have no hard data, admitted “Philip Arreguin , technical deputy general of the National Water Conagua.
Under these agreements, Mexico and U.S. agree to a certain quota every five years. Which corresponds to the period between 2010 and 2015, requires Mexico to pay U.S. 342.7 million cubic meters a year of the Rio Bravo to complete 2mil 558.6 million cubic meters. While the United States, in turn, delivers water to Mexico in two ways: the Colorado River 1 850 million cubic meters and 64 million cubic meters of other tributaries.
“Strictly speaking we do not owe a drop of water to the United States,” said Salmon Castelo, which is not to say that if the drought continues we begin to have problems for a year or year and a half. Not be rule out that possibility but hopefully not become so. We’ve been in worse situations like the one we suffered in 2010 when we went for a much more complicated situation and Hurricane Alex arrived, we filled the dams and we close the previous cycle and then start again. “
– However, the governor of Chihuahua said recently that there is no water to pay the United States and would not be fair to do so without addressing the needs in Mexico before? -We talked with the governor and explained. We are evaluating different actions we want to do with Conagua and the government of the State of Chihuahua.
Felipe Arreguin turn expects the drought to end in June and reverse this situation. “We still have a good margin and after those five years (2010-2015) in the event of extreme drought, we can still negotiate another five years. Yes, we must make efficient use of water, and much care manage, but we’ll see how we deliver water according to the interests, first in Mexico. ” Reported that for two or three years, both countries have discussed how they would face any impact of climate change on precipitation, mainly in the Colorado Basin. “We’ve gone so far as a blueprint to set up a binational desalination plant near Ensenada, and it is located the site where it could carry the water. Surely if the conditions continue, we will work on Bravo River. “It is looking, for example,that U. S. borrow us dams to store water that we not use and give us part of the conduct of its channels, which are more efficient to transport water to Mexico in the irrigation. We are also seeing how we rescued volumes of water in the two countries
