How the urban growth of the Córdoba mountains affects the lack of water

A group of researchers from the National University of Córdoba and CONICET from different branches of science have been studying the problem for several years.

Of that group is part Fernando Barri, who spoke on the subject with City U. In the first place, he explained that the water shortage in Córdoba is a consequence of “an irrational urban development without planning of any kind”.

In addition, he noted that the indiscriminate movement of people from cities towards the mountains, more precisely the middle and upper parts of the basins, has affected the water dynamics.

On that subject, he considered that “there is no state control or regulation”. For this reason, the researcher explained, a large part of the basin is waterproofed with cement and this means that the basins can capture less water.

Following that line, Barri explained the importance of the “sponge effect”, when the rains are captured by the basins of the native forests: “This is fundamental so that it is available in times of drought”.

In addition, he indicated that the other advantage that the conservation of native forests prevents large floods. “Most of that water is retained by the forest”, pointed out and exemplified with the case of the floods in Río Ceballos in 2015

In this way, he emphasized the importance of the sponge effect:

“Of the water that falls in the mountains, 70% or 80% is absorbed by that natural sponge, if I eliminate the native forest that water does not retain and run, then the volume of water that runs is much more and that makes the force of the water is much greater and carries everything in its path. That is why it is essential to conserve what little we have left of our mountain basins “

The influence of the urban movement to the mountains

In addition, Berri highlighted the phenomenon of the migration of the inhabitants of Córdoba capital to inland towns as one of the main reasons that motivate:

“If the urban development had been well planned, it would have been necessary to think that this growth in the mountain areas is sustainable, not to generate this dynamic of the monster capital city that consumes resources.”

On this subject, he stated that it should be thought with other logics that respect natural capital, ecosystem goods and services from which the people of Cordoba are supplied.

“But what is happening now happens that a great demographic growth is generated in rRegions that begin to have difficulties accessing different resources, such as water, “he concluded.
